Patent GB-499206-A (GB)
Title: Improvements in and relating to systems of voltage amplification
IPC: H03F3/40
Filed: 1937-07-15
Abstract: 499,206. Current meters. BRITISH THOMSON-HOUSTON CO., Ltd. July 15, 1937, No. 19643. Convention date, July 15, 1936. [Class 37] [Also in Groups XL and XXXV] Small D.C. variations are amplified to enable them to be measured or to effect a control by applying them to the signal or screen grid of a pentode valve, the other of these two grids being given a pulsating voltage and the resulting A.C. in the plate circuit being amplified in the usual way. As shown, a thermocouple 1 is connected to the inner grid of the pentode 4, the screen grid being connected to the cathode through a valve 5, the grid of which is fed from the A.C. mains in series with a resistance 7. The A.C. developed in the output circuit is amplified at 9 and rectified at 11 and produces a D.C. voltage across the resistance 7 and so modifies the phase of the pentode output, which is amplified at 8 and fed to the grid circuit of the discharge tube 3, relatively to that of the supply, which feeds the anode circuit of the discharge tube. By this means the current is variable continuously from zero to its maximum. The output from the tube 8 may be rectified and led to a measuring instrument, Fig. 3 (not shown).

Title: Improvements in and relating to devices for treating and cleaning fabric materials
IPC: D06F43/00
Filed: 1947-07-23
Abstract: 638,641. Cleaning fabrics. CISSELL, W. M. June 23, 1947, No. 19817. Convention date, June 28, 1940. [Class 138 (i)] [Also in Group XXIX]  A device for controlling the moisture content of steam for use in treating fabrics includes a chamber for mixing steam and water supplied to it through separate passageways each controlled by a valve, the opening of the valves being effected by a common operating member, which ensures that the steam valve must open before the water valve to admit steam or both steam and water to the chamber. Steam from the chamber is applied to the fabrics by a spotting gun. As shown, steam is supplied to a container 7 by a pipe 4. The lower portion 7a of the container 7 forms a condensing chamber 18 having an overflow pipe 17. A valve 11 controls the supply of dry steam from 'the container 7 through a pre-set needle valve 15 to a mixing chamber 20 which can also be supplied with atomized water from the container via a conduit 21, valve 12 and a pre-set needle valve 16. Valves 11 and 12 are normally closed and are operable by depression of a pedal (not shown), the initial depression 'of which opens valve 11, while complete depression opens valve 12 as well. The moisture content of the steam in the mixing chamber is determined by the pre-setting of the needle valves 15 and 16. The mixing chamber 20 is connected by a hose (not shown) to the spotting gun.

Title: Improvements in or relating to refrigerating apparatus
IPC: F25B39/02
Filed: 1948-07-26
Abstract: 642,857. Refrigerating. AERO PIPE & GLASS CO., Ltd., and JULIUS, W. O. July 26, 1948, Nos. 19918 and 20135. '[Class 29] An evaporator element for a refrigerating system comprises a metal plate 1 to which is soldered the flat side of an evaporating pipe 2 of D-shaped cross-section provided at its ends with round transverse supply and discharge pipes 5 and 6, of lesser cross-sectional area than the D- shaped pipe. The pipe 5 communicates with the pipe 2 through an aperture 7 of substantially the same area as that of the pipe 2, as does the pipe 6 if the flow from the evaporator is downwards from the pipe 2. If, however, the flow from the evaporator is upwards the pipe 6 is fed by a small aperture 9 so that liquid from the bottom of the pipe 2 is swept by the vapour stream into the pipe 6. Fig. 6 shows how two such elements may be arranged on plates 10 and 12 the unit so formed being disposed across a cabinet to give an air circulation, the plate 12 supporting ice trays. An ice-making unit may comprise four such elements supporting two banks of ice-trays. Fig. 8 shows a casing 61, for insertion in a cabinet, the side walls of which are cooled by elements 75-77 and which contains further elements 65, 66, 67 for supporting ice-trays 73. In this last embodiment air flows downwards within the casing, clearance being left between the elements 65-67 and the casing walls.

Patent GB-832896-A (GB)
Title: Tool for inserting a pin connector into a socket
IPC: H05K13/04
Filed: 1958-06-25
Abstract: 832,896. Assembling force fits. BURNDY CORPORATION. June 25,1958 [July 9, 1957], No. 20373/58. Class 83 (4). A driving tool for inserting one member into another member to provide a tight connection comprises a shaft, means for securing thereto the member to be inserted, means for latching said shaft in position within the tool, means for creating an impact force upon said shaft when said shaft is inwardly moved further within the tool. The tool 10 for inserting a pin connector into a socket comprises a hollow cap 12 enclosing an impact spring 14 which urges a washer 16 against a seat 17 in the housing 18. A plunger 26 slidable in the housing is provided with a flat spring 28 which urges a ring 32 into a peripheral tapered slot 34 in the housing. The ring is contained in a transverse slot 42 in the plunger in which is longitudinally positioned the spring-loaded connector engaging shaft 44 which is supported in a sleeve housing 58. The shaft terminates in an anvil 76. A hollow and rotatable spring-loaded sleeve 66 surrounds the shaft 44 and abuts a flange 60 on the shaft and is provided with a connector opening 68. The shaft has a similar opening 70 for receiving the taper pin connector 72 with its wire conductor 74 crimped thereto. The taper pin is inserted in the tool by superimposing the openings 68 and 70 and the pin is locked in position by rotating the sleeve 66. In operation the connector pin is placed in the openings 68 and 70 and the sleeve 66 rotated through 90 degrees so that a cam screw 90 aligns with a slot 84 in the sleeve. This permits about <SP>1</SP>/ 16 -inch longitudinal movement of the shaft which forces the ring 32 into the slot 34 and latches the shaft in position. The tool with the extending connector pin are aligned with the socket and the cap 12 is depressed. This causes the ring 32 to engage plunger 26 while riding along the slot 34 and when the ring is cammed into its centred position on the neck 52 of the shaft the plunger is released so that it returns to its original position and the end of the shaft 44 engages the end wall 50 of the plunger bore which drives the anvil 76 against a shoulder 78 on the connector to effect the force fit. In a modification the shaft terminates in a pair of spring-action connector engaging jaws 66a which are compressed by the jaw housing 58a to lock the connector until the impacting cycle is completed. The jaws are threadedly mounted on the shaft to facilitate change in size and replacement.

Abstract: 617,059. Transmitting mechanical power; electromagnetic clutches. ENGLISH ELECTRIC CO., Ltd., and AYRES, W. E. M. Oct. 21, 1944, Nos. 20420 and 25610. [Classes 35 and 38 (iv)] A slip coupling included in a motor vehicle drive has an automatic switch responsive to the reversal of slip to interrupt or reduce the excitation of the coupling when such reverse occurs to permit free wheeling. In the form shown, 4, 5 are the windings of a coupling driving a road vehicle from an internal-combustion engine which also drives the generator 32 for exciting these coils through a rheostat 31 linked to the throttle lever 36. When contact 30a of selector switch 30 is engaged, switch contacts 23, 24 which open when the driven member overruns the driving member of the clutch control the coil circuit, but these contacts are inoperative when the selector switch is turned. Contacts 30d enable the coils to be energized from battery 34 when it is desired to turn the engine from the road wheels. The coupling may comprise a toothed magnetic disc on one shaft between a pair of wound field magnets on the other shaft, as described in Specification 617,060.
