Title: Means for interconnecting the refrigerant compressors in a plural compressor refrigeration installation
IPC: F25B31/00
Filed: 1962-05-09
Abstract: 963,837. Refrigeration. WORTHINGTON CORPORATION. May 9, 1962 [June 16, 1961], No. 17819/62. Heading F4H. [Also in Divisions F1 and F2] Apparatus for adapting a refrigeration compressor for use in a plural compressor installation comprises an adaptor means connected to the compressor and carrying an ejector, and conduits interconnecting the adaptor means of each compressor in the installation so as to maintain an equal level of lubricant in each of the compressors. In a two compressor system as shown, Fig. 1, a motor 6 having a drive-shaft 7 may be mounted inside or outside each compressor 1, the casing 2 of each compressor being divided into a crankcase compartment 4 and a suction compartment 5 by an internal wall 3 having a port 50, and a vent housing a check valve 52, therethrough. Vapour is drawn through the port 50 from the crankcase to the suction compartment by impeller means 51 on the shaft 7, or by the pressure differential between the compartments, and lubricant is forced through the check valve 52 into the crankcase 4. Refrigerant vapour from the low pressure side of the refrigeration system enters the suction compartment 5 through a conduit 40, and compressed vapour from the compressor cylinder, not shown, passes through a passage 8 and discharge compartment 10 to a duct 41 leading to the high pressure side of the system. A pump 12, Fig. 3, at the end of the shaft 7, draws lubricant from the sump 60 of the crankcase 4 through a strainer 15 and pipe 14, and pumps it to a distribution outlet 16 having a pressure relief valve 17. An adaptor plate 61 bolted to the casing 2 has a sight glass 64, a port 63 at the desired level, and an ejector 66 mounted outside the crankcase below the lubricant level and having a discharge outlet 67 within the crankcase. The driving jet for the ejector is derived from a pipe 69 tapping lubricant from the pump outlet 16. The suction inlet of each ejector is connected by a pipe 42, 43 to the port 63 of the adaptor plate on the other compressor. Check valves 44 and 45 ensure that lubricant passes through pipes 42 and 43 only by the action of the ejectors. Specification 916,068 and U.S.A. Specifications 2,076,332, 2,869,775, 2,926,840 and 3,033,009 are referred to.

Abstract: 331,671. Taylor, W. T. June 14, 1929. Systems depending. on static transformers. -A method of obtaining a. three-phase system with a neutral point consists in arranging the windings in the form of an " A." The phase windings are arranged in V connection and a third winding connected across the two legs at points onethird of the length of each leg from the open ends, the third winding being equal to two-thirds of the length of each leg. The middle point of the third winding is the neutral point. Existing systems may be connected to this system as, for instance, in a delta connected system one winding of the delta is removed, leaving a V connection, which is then arranged as above. Increase in line voltage is obtained by increasing the length of the V phases before adding the third winding. Specification 25330/02 is referred to.

Filed: 1942-12-25
Abstract: 582,494. Transmission line switching systems. BOWEN, E. G., TAYLOR, D., and BUDDEN, K. G. Dec. 25, 1942, No. 18362. [Class 40 (iv)] [Also in Group XL] In a radio location system using pulsemodulated waves the transmitting and receiving aerials may be in two or more sections spaced apart in a vertical plane and so connected that either or both can be switched into operation at will to displace the main lobe of the polar diagram in a vertical plane. In the receiver this may be utilised to determine the elevation by comparing the signal amplitude in the two positions of the switch. The leads L1, L2, Fig. 1 (Comp.), to the two parts of the transmitting aerial may be connected alternately or simultaneously to the circuit Tx by a network comprising quarter-wave-length lines arranged as shown in Fig. 1, certain of the lines being adapted to be short-circuited at will by relays S1 ... S4, the energization of which is controlled by a three-way switch to determine the direction of the main lobe of transmission. If relay S1, S3 are energized, power is fed along the path ABDE to circuit L1, while when relays S1, S4 are energized power is fed over path ABDF to circuit L2. If relays S2, S3, S4 are energized, but not S1, power is fed equally to the circuits L1, L2. The feeders 44, 45, Fig. 3, from the two parts of the receiving aerial may be connected alternately to the circuit 46 by energizing diodes V1, V2 in turn, thus varying the shunt impedance of elements 52, 53 connected across the feeders 44, 45 at a distance of a quarter wave from the receiver feeder 46.

Abstract: Doors, windows and the like and their frames are moulded from veneer like strips or sheets of a fibrous material which form when assembled the approximate shape of the article and are of varying lengths or width so that strips of adjacent parts interlock, the strips being saturated with a liquid plastic of the synthetic resin type and, after partial drying, united under heat and pressure in a closed mould.  Preferably after applying heat and pressure the excess steam generated is allowed to escape before further application to bind the mass into solid form.  In forming frames the strips are so laid as to form interlocking tongue and groove joints at the corners.  Hinges and other fittings may be inserted into the mould and moulded into the article.

[Also in Group XVI] A machine for rewinding strips of metal comprises one or more winding spindles driven by an infinitely variable speed gear, the setting of which is varied by a motor controlled by a potentiometer adjusted in accordance with the change in diameter of the roll of material being wound or unwound. A roller 8 carried by a pivoted arm 7 senses increases in diameter of a roller 5a being wound; actuation of the arm 7 operates a potentiometer 6. A second potentiometer 9 is adjusted in accordance with the setting of a variable-speed gear 4 which drives the spindle 5 carrying the roll 5a. An electric motor 10 adjusts the output revolutions of the variable-speed gear 4. A control apparatus, not shown, energizes and de-energizes the motor 10 when a circuit containing the potentiometers 6 and 9 is unbalanced, due to an increase in roll diameter, and then rebalanced when the resistance of the potentiometer 9 is adjusted to equal that of the potentiometer 6 by variation in setting of the variable-speed gear 4. Thus, substantially constant tension is maintained in the material being wound by varying the speed of spindle 5 in accordance with the roll diameter. The tension may be varied manually to produce a hard or soft roll by a further potentiometer 11 connected to the control apparatus. In a modification, the roll being wound is carried by a swinging arm and engages a fixed roller; movement of the arm, due to increases in diameter, causes adjustment of a potentiometer acting in the same manner as the potentiometer 6.

In a diaphragm valve, a follower 27 bears on the diaphragm 15 and is operable alternatively to thrust the diaphragm against its seat surrounding the inlet passage 9 or allow it to lift therefrom, and an annular disc spring having a 3-point contact with the diaphragm and with the valve body around the seat maintains the diaphragm in engagement with the follower. The spring consists of two concentric rings 42, 43 joined by three radial webs, the rings being oppositely undulated. A flanged projection 28 on the follower is loosely held in a bore in the lower end of a screwed actuating spindle 22, a thrust ball 30 being interposed between the projection and the end of the bore. A resilient washer 36 which is compressed between a flange 37 on the stem 22 and the underside of a screwed cap 11 when the valve is in its open position prevents leakage of fluid along the stem. The diaphragm is supported in its upper position by the follower 27 and by a chamfered surface 21 on the lower edge of cap 11. Excessive pressure in the inlet passage 9 will rupture a copper disc 73 and the fluid will escape to atmosphere through radial ports 65 in a screwed cap 60 holding the disc in position. To prevent corrosion of the copper disc by the fluid, the disc is backed by a disc of tin. A lead ring is interposed between the tin disc and the seating 70 therefor.
