Filed: 1949-07-20
Abstract: 662,821. Refrigerating. ELECTROLUX, Ltd. July 20, 1949 [July 22, 1948], No. 19086/49. Class 29 The pressure-equalizing vessel 27 of a continuous cycle inert gas system having an air-cooled absorber coil 22 is formed as an elongated upright member surrounding and, through a hole 28, communicating with a conduit 26 through which flow the cold mixed gases from the gas-heat exchanger 25 to the absorber vessel 16 which is formed integral with the vessel 27 being separated therefrom by a partition 37 apertured to receive the end of the conduit 26. The vessel 27 also acts as a reservoir for liquid refrigerant which is pumped to the evaporator system by a pump 31 as described in Specification 664,208. The condenser 18 and absorber coil 22 are formed as air-cooled coils of flattened helical form connected by common fins and the pressure vessel-absorber-vessel unit 27, 16 is located within the coils. The vessel 27 surrounding the conduit 26 prevents moisture condensation on the latter. The conduit 26 may be completely surrounded by the vessel 27 and the outer jacket of the exchanger 25 which would be contiguous in this case. Alternatively the elbow of conduit 26 could be separately insulated. The auxiliary condenser 32 can be dispensed with and the liquid feed pipe can be formed as a liquid seal U-tube passing through the vessel 27.

Filed: 1945-07-26
Abstract: 611,719. Condensers. BRITISH N.S.F. CO., Ltd., SMITH, K. G., and NEWMAN, L. G. July 26, 1945, No. 19159. [Class 37] In order to prevent fissures 17, 24 from extending through a plastic seal 20 or casing 12 to an electric condenser, the wire leads 11, 19 and other metal parts emerging from the seal or casing are provided with surfaces so shaped and positioned that pressure of the plastic material against the surfaces is increased by shrinkage of the material. In one example (Fig. 2) a cup-shaped member 15 is soldered to each wire lead near the condenser 10, and only small fissures 17 can occur in the casing 12 of wax, paint or other plastic material. The rims of the cups may be slightly inturned as shown, and the sealing is improved by coating the inside and outside of the cups with a non- porous resilient material, e.g. neoprene. In another example (Fig. 3), the edge of an opening in a metal container 18 is spun over to form an endless channel 21 whose cavity faces away from the axis of the case, and a mass 20 of insulating material seals the opening. A wire lead 19 extending through the seal has a cupshaped member 22 attached to it, shown with its cavity facing inwards. The cup-shaped members may alternatively be formed, integrally with the wires, e.g. by turning. Specification 567,426 is referred to.

Patent GB-432390-A (GB)
Title: Improvements relating to hydraulic controls, particularly those requiring positive locking
IPC: F15B13/01
Filed: 1934-07-05
Abstract: 432,390. Hydraulic transmission of power. EXACTOR CONTROL CO., Ltd., and PARKIN, W. H., Dorland House, Lower Regent Street, London. July 5, 1934, No. 19830. [Class 69 (ii)] A two-pipeline hydraulic control system has a valve or valves in each pipeline, at least one valve being capable of being opened by pressure generated within the receiving unit, and at least one being capable of being opened by pressure in the opposite pipeline through the medium of a byepass. In the arrangement shown in Fig. 1, pressure from the pipe 1 may pass to the upper end of the cylinder 3 by opening a valve 8, or both valves 8, 10. Liquid from the other end of the cylinder passes to the pipe 2 by opening a valve 17 against a strong spring 18. When there is no pressure in the pipe 1, the piston 4 cannot move down under external force, unless the force suffices to overcome the spring. When the pipe 2 is the pressure pipe, a valve 16 carrying the valve 17 is opened against a light spring 16<a>, and liquid passes to the lower end of the cylinder; simultaneously, pressure acts through a byepass 14 on a piston 11 to open the valve 10 against a spring 13, so that liquid from the upper end of the cylinder can pass to the pipe 1. The piston is thus positively locked against upward movement when there is no pressure in the pipe 2. The valves operate to take care of expansions and contractions due to temperature changes, and the receiving cylinder 3 has resilient stops 4<a>. In another form, the pipe 1 is connected to a casing having a non-return valve 23, Fig. 2, and a ported plunger 26 acted on by a light spring 27 and by pressure in a chamber 28 connected to the byepass 14. In a further form, the valve 16, 17 is replaced by the valve unit shown in Fig. 2, or the valve unit 8, 10 ; the byepasses being then connected to points between the valves and the receiving cylinder.
