Title: Improved electric switch
IPC: H01H13/02
Filed: 1970-06-23
Abstract: 1278860 Indicators for switches SWFSPEZIALFABRIK FUR AUTOZUBEHOR GUSTAV RAU GmbH 23 June 1970 [27 June 1969] 30308/70 Heading H1N A push-button switch wherein a continuously lit lamp 12 illuminates the push-button 19 has a rib 15 of transparent material extending from the region of the lamp 12 to an exteriorly visible surface 18, and a movable shutter 25 actuated by the button 19 controls the emission of light therethrough. As shown, the rib 15 lies between two push-buttons and the shutter 25 is loaded by a compression spring (27, Fig. 1, not shown) urging it to the right (Fig. 2). A portion (21, Fig. 1, not shown) of the push-button 19 normally holds shutter 25 in the light-obturating position shown, but depression of the button allows spring (27) to move the shutter and light from lamp 12 passes via a colour filter 26 to the outlet 18. Aluminium coating 17 or black paint prevents radiation of light in undesired directions. Lamp 12 is carried in a holder 11 retained in the switch housing by notched portions 13 and 14. A common shutter 25 may be controlled by a plurality of push-buttons.

IPC: F04C14/02
Filed: 1949-11-26
Abstract: 665,808. Rotary pumps. COOK, C. A. (Soc. Nationale d'Etude et de Construction de Moteurs d'Aviation). Nov. 26, 1949, No. 30370/49. Class 110(ii) A fluid supply system comprises two pumps, each with constant output, and bypassing arrangements to return part of the fluid to source 1 when a pre-determined pressure is reached in the system. Fig. 1 shows two gear pumps 2a, 2c supplying a system 9 in common. When a pre-determined pressure is reached in 9, a valve 10 is forced to close and a piston 16 is lifted by delivery pressure acting through a pipe 17 to allow the delivery from the pump 2c to pass, by way of ports 19, 20, to the suction of the pump 2a. Upon further increases in pressure in the system, bypass valves 12b, 12a open in succession, to return the delivery of pump 2a to source 1. The two pumps may be axially displaced on two shafts in a common casing. In a modified arrangement, Fig. 5 (not shown), the by-passes 12a, 12b are replaced by a single by-pass having a valve which progressively opens under increasing pressures. A third arrangement, Fig. 9, provides for successive short-circuiting of the two pumps. As the piston 21 is forced upwards it opens byepasses 12<SP>1</SP>, 17<SP>1</SP> under successive, increasing pressures. The system may be used for the distribution of lubricant.

Title: Refrigeration systems including a purge recovery arrangement
IPC: F25B43/04
Filed: 1958-09-25
Abstract: 899,074. Refrigerating. CARRIER CORPORATION. Sept. 25, 1958 [Feb. 3, 1958], No. 30708/58. Class 29 A mixture of refrigerant vapour and foreign gases is led through pipe 18 and restriction 19 from condenser 12 to a chamber 20 in which the refrigerant vapour is condensed on an auxiliary evaporator 23 fed with refrigerant from the condenser 12 through pipe 40 and valve 41, the resulting condensate flowing to the main evaporator 15 and the foreign gases being blown off through valve 28. The operating coil of valve 28 is in series with two switches 55, 56 actuated in response to the pressure differences between the condenser and chamber 20 and the condenser and evaporator 15 respectively. When the system is idle, switches 55, 56 are made and open respectively, valve 28 being therefor closed. When the system is started, the gases and any moisture flow through pipe 18 to chamber 20 where the moisture and refrigerant condense. Reduction in the pressure of evaporator 15 closes switch 56 and therefor valve 28 opens to vent the foreign gases. This causes a reduction of pressure in chamber 20 so that switch 55 is broken and valve 28 is closed until the chamber next fills with gas. Water from the chamber 20 can be drained off through pipe 30 and refrigerant is fed to evaporator 15 through pipe 35 under the control of float valve 24. The system shown is of the compression type having a two stage compressor 10 the high pressure stage of which is connected to liquid refrigerant cooler 14. The invention may also be applied to absorption systems.

Abstract: 752,186. Magnetic couplings. ROTAMETER MANUFACTURING CO., Ltd. Nov. 2, 1954 [Dec. 5, 1953], No. 31712/54. Class 35. [Also in Group XIX] The vertical movement of a float used in a liquid-flow or level-indicating apparatus is indicated by a pointer which is coupled to the float by a magnetic coupling device comprising spaced permanent or electromagnets on a rectilinearly movable driving member and an angularly movable driven magnet member. The driving member which is moved by the float (not shown) consists of a permanent magnet bar 3 carrying four radially disposed permanent magnets 1, 1<SP>1</SP>, 1<SP>11</SP>, 1<SP>111</SP>, the polarities of these magnets being as shown in Fig. 1 and a spaced and inverted similar member shown in dotted lines. The driven member carries a pointer 4 and consists of a support 6 on which are mounted two parallel permanent magnets 8, 8<SP>1</SP> and two opposed permanent magnets 9, 91, the polarity of the outer ends being such so as to produce an arc-shaped flux in a plane parallel to the direction of movement of the driving member so that as the latter moves upwards the interaction of the fluxes of the two members of the coupling causes the driven member to rotate clockwise about a pivot 7. Modifications of the driving member magnet system include two opposed magnet bars with large disc-shaped pole pieces at the opposite ends as in Fig. 2 (not shown) or two truncated-cone shaped permanent magnets as in Fig. 3 (not shown).
