Cutting sleeve

Unlike injection blow molds, which are mounted onto a die set, extrusion blow molds are fitted with hardened-steel guide pins and bushings to ensure that the two mold halves are perfectly matched. Dies, mandrels, blow-pin cutting sleeves, and neck-ring striker plates are made from tool steel hardened to 56-58 HRC. 

An intensive radial load is created when operating near the shut-off head and the shaft deflects at about 60° from the cut-water. This concept is explained in Chapter 9 Shaft Deflection . The pump will be noisy, will vibrate and maintenance on seals, bearings and shaft sleeves is expected.

Rubber Sleeve Core Barrels. Rubber sleeve core barrels are special application tools designed to recover undisturbed core in soft, unconsolidated formations. As the core is cut, it is encased in the rubber sleeve that contains and supports it. Using face discharge ports in the bit, the contamination of the core by circulating fluid is reduced. The rubber sleeve core barrel has proven to be a very effective tool, in spite of the fact that the rubber sleeve becomes weak with a tendency to split as the temperature increases about 175°F. 

Cuttings consisting of one or two leaves are usually rooted in plastic sleeves filled with an appropriate rooting medium. The sleeves are cared for in a nursery with the same precautions exercised as for seedlings. Callus development occurs in a few weeks, rooting begins in 6 to 8 weeks, and shoot growth is substantial in 4 to 5 months.21... 

But we still need to know the actual local ambient in the immediate vicinity of the capacitor. Nearby components may also be heating the capacitor. Therefore a common and perhaps conservative industry practice is to cut the outer sleeving of the capacitor and to insert a thermocouple under the sleeve in contact with the metal case. That way small air draughts don t affect the results. We then take this measured case temperature as the effective ambient for the cap, unless of course we know better. Suppose the case temperature is measured to be 70°C in this way, then the conservative estimate of capacitor life is... 

When a scheduled repair to a facility is made by cutting out the damaged portion of the pipe as a cylinder and replacing it with another section of pipe, the replacement section of pipe shall be subjected to a pressure test. The replacement section of pipe shall be tested to the pressure required for a new facility installed in the same location. The tests may be made on the pipe prior to installation, provided nondestructive tests meeting the requirements of the applicable Part of this Code are made on all field girth butt welds after installation. If the replacement is made under controlled fire conditions (hydrogen in the facility), full encirclement welded split sleeves may be used to join the pipe sections instead of butt welds. 

Doing chemistry means making a lot of measurements. The point of spending a pile of money on cutting-edge instruments is to make really good, really precise measurements. After you ve got yourself some measurements, you roll up your sleeves, hike up your pants, and do some math. 

B. 2-Methylbenzyldimethylamine. Caution This preparation should he conducted in a good hood to avoid exposure to ammonia.) To 800 ml. of liquid ammonia contained in a 2-1. three-necked flask fitted with a rubber slip-sleeve-sealed wire stirrer and an aircooled reflux condenser, sodium is added in small pieces until the blue color persists (Note 6). At this point 0.5 g. of granulated ferric nitrate is added, and then 27.8 g. (1.2 gram atom) of sodium (cut into approximately 0.5-g. pieces), is introduced at such a rate that stirring is not hindered. After all the sodium is added (about 15 minutes), the mixture is stirred until the blue color disappears and the grayish-black suspension of sodium amide remains (15-20 minutes). Stirring is discontinued, and the mixture is swirled to wash down the mirror of sodium which forms on the upper walls of the flask (Note 7). 

Natural single-crystal diamond and carbonado can now be replaced in many industrial uses by sintered diamond tool blanks. Such tool blanks are available in disks and cores. The disks, or sectors of disks, consist of a thin (0.5—1.5 mm) layer of sintered diamond up to about 50 mm diameter on a cemented tungsten carbide-base block about 3—6 mm thick. Using diamond abrasive, such blanks can be formed into cutting tools of various shapes. Typical tool blanks are shown in Figure 9. The wire dies have diamond cores up to 10 mm in diameter and 10 mm in length, which are encased in a cemented tungsten carbide sleeve up to 25 mm in diameter. 

Rubber policemen are simply rubber sleeves (obtained from Mac-Farlane Robson Ltd Appendix 3), which fit over the ends of glass rods and provide a Soft surface with which cells may be scraped from their substratum. Alternatives for use with dishes are wedges of silicone rubber cut from bungs and stuck on hypodermic needles (Fig. 4.1). These also have the advantage that they can be readily sterilised by autoclaving. A collapsible type of windscreen wiper (Fig. 4.1) is readily constructed for scraping cells from the inside of roller bottles. Scrapers can be obtained from Costar (Appendix 3).
