Filled containers

In dmmming and the filling of tank cars and tmcks, where the vessel is initially empty, the amount of material being transferred that could be released by displacement depends on how much evaporates during the filling. Rarely does a material evaporate so quickly that the entire volume of displaced gas is saturated. More likely the initial release at the start of filling contains only a small amount and the concentration increases toward saturation... 

In critical applications, cap bolts with grease-filled containers. In some instances, epoxy materials have been used to fill such caps (with limited success). 

It is convenient to calculate a TNT equivalent of a physical explosion to use the military results of Figures 9.1-4 and 5. Baker et al. (1983) give a recipe for the rupture of a gas filled container assuming expansion occurs isothermally and the perfect gas laws apply (equation 9.1-25), where W is... 

This is added to reduce or prevent skin formulation in partially filled containers. 

When a proportional counter is. used in conjunction with a pulse-height selector, the occurrence of an escape peak may vitiate the results. Assume that the counter filling contains argon, whose K edge is at 3.87 A, and suppose that the pulse-height selector is set to select an x-ray line 3f shorter wavelength the intensity of which is to be measured. This line will excite the K lines of argon. To the extent that these lines are... 

For comparing the relative loss of a flavor component from a container, we have found the sniff test (6) very useful, especially when gas concentration measuring techniques were not available. Typical results of this type of test are shown in Table II. Each filled container was held in a glass jar for approximately 48 hours. The results are stated in qualitative, subjective terms such as slight, strong, or undetectable. The...

Application verification (AV) monitors are devices that are placed within test plots to measure actual spray deposition that occurred during application. The main function of AV monitors is to show whether or not the intended amount of test material was actually deposited on the soil surface. Application monitors consisting of soil-filled containers, paper disks, polyurethane foam plugs, and glass Petri dishes have all been used successfully for this purpose. Prior to using a monitor in the field, it is important to determine that the test substance can indeed be successfully extracted from the monitor and that the compound will be stable on the monitor under field conditions... 

Quite often empty containers are stored in such a way that they are subject to the weather and to contamination that may result. A quick wipe with a dirty rag is all that is often used to clean them before filling Containers really do need to be stored in a clean, warm environment in their original packaging to avoid this type of problem. 

Various methods have been devised to prevent oxidation during storage. The most obvious is to store the LSD in nitrogen filled containers, but the excellent protection thus afforded is of course lost when the bottle or ampule is opened. Another method is to use an antioxidant Brown and Smith recommend ascorbic acid. A more sophisticated method, recommended on the highest authority, is to... 

Use could be made of aerodynamic effects such as Bernouille or Magnus effects to generate quite high forces. Water could also be used as a source of variable mass, filling containers which can change the balance of various hinged parts of a sculpture. 

However, there remain numerous end-use applications which require significant improvements in the properties PET has to offer. These include higher tensile strength and modulus for tyre reinforcement yams and monofilament applications, higher temperature resistance for hot-fill containers and films, and greater gaseous barrier for longer shelf-life requirements (e.g. fruit juice and beer markets). 

The entire cycle takes only a few seconds, and therefore the open container is only minimally exposed to the surroimding clean room/air shower environment. The mold then opens and the filled containers surroimded by excess polymer are released. Excess plastic is removed (typically on line by means of a mold-specific cropping tool). 

In order to avoid a surge of helium when the spray valve is opened (as this would contaminate the entire environment) it is advisable to install a choke valve to adjust the helium quantity, directly before or after the spray pistol (see Fig. 5.15). The correct quantity can be determined easiest by submerging the outlet opening in a container of v/ater and setting the valve on the basis of the rising bubbles. riable-area flowmeters are indeed available for the required small flow quantities but are actually too expensive. In addition, it is easy to use the water-filled container at any time to determine whether helium is still flowing.

Prior to initiating loaded chamber heat penetration studies, a container mapping study should be conducted. The intent of this study is to determine the coolest point within a liquid-filled container.

If multiple sizes of the same container/closure configuration are aseptically filled, selective sizes may be used for media fills. Containers with the widest diameter openings and slowest line speed should be included in the media-filling regimen and may be representative of worst-case conditions. However, the small containers may be representative of these conditions because of lack of container stability in the line operations. 

Growth promotion ability of the medium in final filled containers must be demonstrated using ten randomly selected containers for each challenge organism (more than 100 microorganisms per test container). 

After completion of the incubation period, the media-filled containers shall be visually inspected for the presence of microbial growth. 

Growth promotion shall be performed per standard test method (provide number), where USP growth promotion test organisms and representative panel of microorganisms normally found environmentally or in the product bioburden shall be used in growth testing the medium-filled containers.

The density of explosive fillings contained in munitions should be as close as possible to the theoretical maximum density (TMD) of formulations, which is calculated from the crystal densities of ingredients of an explosive formulation, taking into account their relative proportions. The density of a formulation directly affects its performance as is shown by an empirical relationship (Equation 3.1) ... 

Because of its extreme chemical reactivity, calcium metal must be carefully packaged for shipment and storage. The metal is packaged in sealed argon-filled containers. Calcium is classed as a flammable solid and is nonmailable. Sealed quantities of calcium should be stored in a dry, well-ventilated area so as to remove any hydrogen formed by reaction with moisture. 

The growth of malo-lactic bacteria in wines is favored by moderate temperatures, low acidity, very low levels of S02, and the presence of small amounts of sugar undergoing fermentation by yeast. It is frequently possible to inoculate a wine with a pure culture of a desirable strain of bacteria and obtain the malo-lactic fermentation under controlled conditions. The pure-culture multiplication of the selected strain of bacteria is difficult, however. It is also difficult to control the time of the malo-lactic fermentation—sometimes it occurs when not wanted, and at other times will not go when very much desired. For the home winemaker it is probably most satisfactory to accept the malo-lactic fermentation if it occurs immediately following the alcoholic fermentation. The wines should then be siphoned away from deposits, stored in completely filled containers at cool temperatures, and have added to them about 50 ppm S02. If the malo-lactic fermentation does not take place spontaneously and the wine is reasonably tart, the above described regime of preservation will likely prevent its occurrence. When the malo-lactic transformation takes place in wines in bottles, the results are nearly always bad. The wine becomes slightly carbonated, and the spoiled sauerkraut flavors are emphasized.

PB film is usually made by the blown film process, but also can be cast oil drill lolls. Film applications include food and meat packaging, compression wraps, and hot-fill containers. The material can be formulated to provide a wide range of seal strengths for peelable or easy-opening packaging.
