Title: Reversible refrigerating system
IPC: F25B13/00
Filed: 1960-05-16
Abstract: 952,873. Refrigerating. YORK SHIPLEY Ltd. (York Division, Borg Warner Corporation). May 16, 1960, No. 17228/60. Heading F4H. In a reversible compression refrigerating system having indoor and outdoor heatexchangers 15 and 14, a single automatically controlled valve 17 brings about either series or parallel working of the compressors 10, 12. Series working is instituted by a low outdoor temperature acting on thermostatic bulb 22 to reduce the pressure in bellows 18 and move valve 17 into the position shown. Valve 16 conducts the high pressure gaseous refrigerant to heatexchanger 15 acting as a condenser, but it can be independently adjusted to interchange the evaporator/condenser functions of the heat exchangers 14 and 15. The liquid refrigerant passes through capillary 29 and is evaporated at reduced pressure in heat-exchanger 14 before it is returned to the compressors 10 and 12. In the bellows expanded position of valve 17 (Fig. 1, not shown), part of the low pressure gaseous refrigerant by-passes compressor 10 by going directly from pipe 33 to pipe 30 and the output from compressor 10 by-passes compressor 12 and enters pipe 32. Specification 800,246 is referred to.

Title: Improvements in vacuum apparatus for raising liquids
IPC: A01J7/00
Filed: 1937-06-22
Abstract: 497,658. Vacuum apparatus for raising liquids. TURNER, C. W. M. June 22,1937, No. 17317. [Class 102 (ii)] Apparatus for raising liquids, primarily intended for raising water by means of the vacuum of a milking machine, comprises a float chamber 4 at an intermediate level, and an upper reservoir 1. The latter is higher at one end, which is connected to a source of vacuum bv a pipe 2. The lower end is connected by a pipe 3 to the float chamber. The vacuum in the chamber 4 draws water from the well through a pipe 6 until the rising of a float 7 closes the pipe 3 by means of a cup 16. At the same time the float opens a vent valve 13 having an adjustable stem. The vacuum in the reservoir 1 then draws the water from the float chamber through a pipe 5, until the valves 16, 13 are reversed by the fall of the float 7, due to water retained in a cup 9 on the stem 8 of the float. In a modification, the reservoir 1 is replaced bv a second float chamber, which discharges into a reservoir.

Title: Improved method of diminishing the risk of back-ignition in series-connected electric rectifiers
IPC: H02M7/10
Filed: 1922-06-26
Abstract: 182,462. Akt.-Ges. Brown, Boveri, et Cie. July 2, 1921, [Convention date]. Vapour apparatus, arrangements of. - In mercury-vapour rectifiers connected in series through transformer windings, the risk of backignition is diminished by magnetically interlinking the series-connected anode circuits. In the arrangement shown in Fig. 2, the rectifiers G1 G2, are supplied from the secondary windings S1, S2 of a three-phase transformer the direct-current net Ng being connected to the neutral point O1 of the winding S, and to the cathode of the rectifier G2. The anode currents of the same phase in each rectifier are interlinked inductively in pairs by the windings a - - f, as shown. In normal working, when corresponding currents are flowing simultaneously through both rectifiers, the currents in these windings act as choking-coils in respect of backignition or short-circuit currents occurring in one only of the rectifiers. In another arrangement, Fig. 3, each rectifier is supplied from a pair of secondary windings displaced in phase and having separate neutral points as shown. The various anode currents are linked together bv the windings a - - d of which a is inductively interlinked with c, and b with d. In another arrangement, Fig. 4, the secondary windings S<1>, S<2> allotted to the rectifiers G1, G2 are similar and symmetrical polyphase systems and are shifted in phase as shown, adjacent phases in each rectifier, such as the phases 1, 1', being linked together by windings a, b, &c. This interlocking causes an overlapping of the anode currents in addition to the choking effect on backignition currents. The windings S1 S2 may be on two transformers, the primary windings of which are connected in series. The inter-linking in this arrangement may be made on six single-phase tranformers, or on a polyphase transformer with one limb unwound.
