Title: Improvements in absorption refrigerating apparatus
IPC: F25B33/00
Filed: 1957-01-18
Abstract: 826,511. Refrigerating. ELECTROLUX Ltd. Jan. 18, 1957 [Jan. 19, 1956; Jan. 5, 1957], No. 1931/57. Class 29 In a continuous cycle absorption refrigerating system substantially all the refrigerant vapours necessary for the operation of the system are generated in the liquid circulating pump and are then analyzed in a column of rich absorption solution the height of which controls the quantity of which controls lated by the pump and the composition of the vapours flowing to the condenser. The pump 10 is supplied with rich absorption solution from a standpipe 15 fed through pipes 16, 18 from the absorber 21, and is heated by an electrical cartridge 13 insulated from the remainder of the apparatus. Liquid raised by the pump is discharged to pipe 22 from where it flows to the liquid heat exchanger 17. Vapour flows through pipe 27 which discharges into the standpipe 15 at a depth H below the level of rich solution. The column H has the effect of applying a counterpressure to the pump 10 thus varying the amount of liquid raised and also provides a source to which the heat of the vapours is applied thus generating further refrigerant vapour in condensing the absorbent vapour. Preferably heat is applied to the pump and H so chosen that the ratio weight of liquid lifted by pump to weight of refrigerant vapour generated is 9:1 whereas the ratio weight of liquid lifted to weight of refrigerant passing to condenser is 4¢:1. In addition the solution entering the pump contains about 30% refrigerant whereas the solution flowing to the absorber contains less than 20% refrigerant. A small amount of heat from the electric cartridge may be allowed to flow directly to the standpipe 15.

Abstract: 969,832. Laminates and laminating. ALLIED CHEMICAL CORPORATION. Jan. 16, 1963 [Jan. 31, 1962 (2)], No. 1990/63. Heading B5N. [Also in Division E1] An acoustical ceiling or wall tile, e.g. a rigid mat of wood fibre, sugar cane fibre, rock wool, or glass wool with a resinous binder, has a thermoplastic layer, e.g. rigid P.V.C., other vinyls, polythene or polypropylene, bonded round the edges so that it covers but is not bonded to the face of the tile. The tile is bonded when in a " bone dry " condition, i.e. drier than may be expected in normal conditions, so that the thermoplastic layer will not sag when the tile is subjected to varying humidities. Tongues 31 and grooves 33 (Fig. 19) each along two adjacent edges of the tile render them self-interlocking. In the apparatus, adhesive is applied to the edges of the tile as it passes along two perpendicular conveyer belts (Fig. 1, not shown) and then the tiles are passed through an oven (Fig. 2, not shown) so that they are in a " bone dry " condition. Fifteen tiles are then loaded into a caul plate, Fig. 8, which is moved into position on a vacuum bed 19, Fig. 7, beneath a thermoplastic film clamped in a frame 171, 172. Fifteen shields 226 are then lowered on to the film and the strips between them heated. The vacuum bed 191 is raised until the tiles T are in contact with the film, when air is evacuated through the pipe 202 to suck the film into engagement with the tiles, the softened thermoplastic being sucked against, and bonded to, the edges of each tile. The caul plate is then removed and the film between adjacent tiles severed by hot copper wires. The edges of the tile are trimmed while they pass along two perpendicular conveyers (Fig. 12, not shown), and paraffin wax or other waterproof material may be applied to the base of the tile.

Filaments of an acetone-soluble acrylonitrilevinylidene chloride copolymer are made by forming filaments from an acetone solution of the copolymer by wet or dry spinning; stretching the freshly extruded filaments so obtained from 75 to 300% at a temperature in the range of 15‹ to 40‹ C., steaming the thus stretched fibres under conditions such that either no stretching of the filaments takes place or the filaments are stretched no more than 25% and, as soon as possible after the steaming operation, stretching the filaments from 500 to 2000% at a temperature not less than 95‹ C. The steaming operation is preferably effected while they are passing over a thread storage device such as a thread advancing reel or a pair of rollers enclosed in a chamber to which steam is admitted and which is maintained at 70‹ to 100‹ C. The residence time of the fibres within the chamber is preferably 15 to 35 seconds. The steaming of the filaments is preferably effected under such conditions that the denier of the filaments remains unchanged during the steaming. However, a small degree of stretch can be applied during the steaming but should not exceed 25% Throughout the Specification the degree of stretching is expressed as the percentage of the increased length on the length immediately before stretching of the filaments. The process is an improvement on that described by the Applicants in Specification 898,734.
