Box enclosure

The main concept of the box design is to maximize the area of constant pressure, which is exerted by the polyethylene bag, in order to provide a reasonable zero-slope flow rate. Consequently, a rectangular box enclosure was used, because the forces would be transferred perpendicularly to most of the surface of the drug bag. This also explains why two bags were used instead of one. 

An electronic box that consumes 200 W of power is cooled by a fan blowing air into the box enclosure. The dimensions of die electronic box aie 15 cm X 50 cm X 50 cm, and all surface.s of the box are exposed to the ambient except the base surface. Temperature measurements indicate that the box is at an average temperature of 32 0 when the ambient temperature and the temperature of the surrounding walls are 25 C. If the emissivity of the outer surface of the box is 0.75, determine the fraction of the heat lost from the outer surfaces of the electronic box. 

Enclosure A box, cupboard, or room in which a toxic process is carried out in safety. 

Glove box A sealed enclosure used for handling toxic products by means of long impervious gloves sealed to form part of the enclosure. 

To retard corrosion and to facilitate future maintenance (e.g., allow the non-destructive removal of threaded Junction box covers), all threaded connections should be lubricated with an antiseize compound which will not dry out in the environment. If lubricant is applied to the threaded (or flanged) portion of covers of explosion-proof enclosures, the lubricant must have been tested and approved as suitable for flame path use. It is cautioned that some lubricants contain silicone, which will poison most catalytic gas detector sensors and should not be used near gas detectors. 

In metal-enclosed assemblies, the equipment is contained within a grounded metal enclosure. In metal-clad types, separate compartments are provided for the circuit interrupter, the components connected to one side of the interrupter (e.g. the cable box) and those connected to the other side of the interrupter (e.g. the busbar chamber and the control equipment). 

Adult females and weaned juveniles of both sexes held in outdoor flight enclosures roost boxes treated with 69,300 mg PCP/kg and wood shavings contained 65,000 mg/kg FW All dead within 24 h (90% survival in controls after 32 days). Carcasses of dead bats had 13.1 mg PCP/kg FW. Total PCP burden, in pg, ranged from 17-152 in whole body and 29-181 in fur. Maximum tissue concentrations, in pg/kg FW, were 99 in fat, 65 in liver, 25 in kidney, and 30 in remainder (Shore et al. 1991)... 

In the enclosure rule, all paths from A back to A that use only associations defined within the box (or that do not use any links marked cross ) are guaranteed to get back to the same instance of A that is, all links lie within the tree of objects that is rooted at self A. By contrast, although a.b.x.d is certainly a member of type A, it need not be = a. 

Valves on distribution mains, whether for operating or emergency purposes, shall be located in a manner that will provide ready access and facilitate their operation during an emergency. Where a valve is installed in a buried box or enclosure, only ready access to the operating stem or mechanism is implied. The box or enclosure shall be installed in a manner to avoid transmitting external loads to the main. 

There are perhaps hundreds of miscellaneous unsaturated polyester resin construction applications. These would include window frames, doors, cabinet enclosures, electrical boxes, etc. In addition, recent developments bode well for unsaturated polyesters in construction markets. Concrete rebar, bridge construction and general infrastructure repair are examples of growing construction applications. 

Semicontinuous polymerization experiments were carried out in a stainless steel enclosure (dry box) under a dry nitrogen atmosphere in three neck flasks (11) equipped with overhead stirrer and an inlet for the continuous introduction of precooled inifer/isobutylene/ solvent feeds to stirred, dilute BCI3/solvent charges. Experiments with binifer were performed at -80°C by the use of CH3Cl/n-hexane solvent mixtures (80/20 v/v), with trinifer at -40°C using CH3CI...

A tenfold increase of the intensity may be obtained at the cost of a somewhat reduced thermal stability by omitting the draft shield and mounting the shutter and lamp assembly directly on top of the sample holder enclosure block. Since the heat production of the fluorescent lamp is very small the whole irradiation equipment could be mounted within the standard glove-box. 

If a spare rotor or element is purchased, it shall be prepared for unheated indoor storage of 3 years. Storage preparation shall include treatment with a rust preventive and enclosure in a vapour barrier envelope with slow release vapour phase inhibitor. The rotor or element shall be boxed for the type of shipment specified. A rotor shall have a resilient material (but not lead, TFE or PTFE), at least 3 mm (0,12 in) thick, between the rotor and its support cradle support shall not be at the rotor s Journals. An element shall have its rotor secured to prevent movement within the stator.
