Title: Improvements in rotary electrical switches
IPC: H01H9/22
Filed: 1944-03-21
Abstract: 582,193. Rotary switches. CARLISLE ELECTRICAL MANUFACTURING CO., Ltd., COLLINGS, S. H., and TAYLOR, W. March 21, 1944, No. 5217. [Class 38 (v)] [Also in Group XXXVI] A rotary electric switch comprises two parts which may be uncoupled by rotation of a locking member mounted coaxially with the operating handle. The fixed part of the switch, Fig. 4, comprises a base 19 carrying four fixed contacts of the type described in Specification'582,194 and four pillars 18 on which is a plate 20 with a substantially square hole through which passes part of the removable portion of the switch, Fig. 3, of which a face block 40 lies on the plate 20. A handle 12 is mounted on a boss 26 on which is a pin which engages a loop of wire on a spindle 27 carrying four movable contacts 25 connected in pairs by fuses 24. A locking ring 11 surrounds the boss 26 and carries plates 36 on studs 37 passing through arcuate slots 41 in the face block 40 and may be rotated to pass the plates 36 under or free from plates 22 fixed across two diagonally opposite corners of the square hole in the plate 20, Fig. 4. When the switch is rotated into the 'on' position a lug 13 on the boss 26 engages a shoulder 14 in a groove 42 in the locking ring 11 which is moved to the locked position so that the parts cannot be separated or put together if already separate. Lost motion allows the parts to remain locked when the switch is in the 'off' position. The switch has a snap action due to the co-operation of the cam 32 with the spring urged pin 33.

Patent GB-1187562-A (GB)
Title: Improvements in Electric Heating Devices
Inventor: EISLER PAUL
IPC: H05B3/34
Filed: 1966-08-08
Abstract: 1,187,562. Electric heating devices. P. EISLER. 8 Aug., 1967 [8 Aug., 1966], No. 5416/66. Heading H5H. In an electric heating device comprising a flat section heating element arranged in zig-zag formation with the major surfaces of each limb 12 in a substantially common plane, the heating element consists of a conductive element loosely carried in an insulating sheath and is secured by means which exert longitudinal tension solely on the sheaths of the limbs. As shown, the apices 13 of the zigzag element are passed over glass or ceramic bobbins 14 which are rotatably mounted on rods 15, 16, at least one e.g. 16, being biased away from the other by springs 18 to tension the sheaths of the heating elements. The weight of the rods 15, 16 is taken by brackets 17, 18 secured to a metal framework. The smooth surfaces and rotatable mounting of bobbins 14 ensures substantially constant tension on the sheath. Each bobbin may support one or more apices of the zigzag element and may be longitudinally adjustable. The heating element may comprise a crimped metal e.g. steel or aluminium foil enclosed in a single layer or two layer sheath, carbon or graphite coated tapes or carbon layers between metal foils. The sheaths can be made of plastics material or fabrics e.g. fibre glass fabric, quartz fabric, nylon, " Terylene " (Registered Trade Mark) or cotton fabric. Alternatively the heating element comprises a plurality of transversely crimped, parallel strips which are mounted in individual pockets in the sheath or sheaths. To assist in maintaining the zigzag element in a plane tapes 22 which are maintained under tension by springs secured to the framework may be interwoven with the heating element. A loosely woven fabric, with the sheathed conductors as weft and tapes 22 as warp may be stored in a roll and used in making the heating device. The heating device may be used in drying, baking or curing ovens or tunnels, and a web may pass successively through pairs of superposed heating devices. A reflecting dividing wall may be provided between successive superposed pairs. Where a water permeable insulating sheath is used for the heating elements water vapour may be driven off by connecting the device to a lowvoltage supply prior to applying full load. If the device is used to operate in an inflammable atmosphere it is enclosed in a perforated box filled with air or inert gas at a slightly higher pressure than the inflammable atmosphere.

Title: Improvements relating to the setting of rivets
IPC: B21J15/36
Filed: 1941-04-28
Abstract: 542,308. Riveting. BAXTERS (BOLTS, SCREWS & RIVETS), Ltd., and DENT, W. C. April 28, 1941, No. 5459. [Class 83 (iv)] Sets and snaps.-In riveting by means of solid rivets 7 these have each a small conical or rounded recess 14, Fig. 7, in the end face of the shank which is engaged by a corresponding projection 15 in the head forming recess 4 or in a work locating pin 1, Fig. 3, so as to centre the rivet shank in the recess before upsetting. The rivet may be moved by a holder 8 until the shank engages the pin 1 which has located the work 5. The tool 6 then forces the rivet through the work and out of the holder, the pin 1 moving down against the action of a spring 3, until its end is in the same plane as the bottom of the recess 4. Continued movement of the tool 6 presses down the rivet work and work-support 10, against the action of a spring 12, Fig. 6, thus upsetting the end of the shank. The action is similar if the pin 1 is omitted but in this case the shank is not guided while passing through the work but is centred when it engages the tool 2.

Title: Improvements in or relating to transformer arrangements
IPC: G05F3/06
Filed: 1952-03-03
Abstract: 708,980. Transformers; automatic regulation. SOLA ELECTRIC CO. March 3, 1952 [March 16, 1951], No. 5488/52. Classes 38(2) and 38(4) A transformer arrangement having a primary winding 36 and a secondary winding 38 loosely coupled on a magneto core 10, a condenser 11 in circuit with the secondary winding 38 of such a capacity that when the transformer is excited with a voltage of predetermined magnitude and frequency a condition of series resonance exists, and a load circuit connectible to a predetermined portion of the secondary winding, is characterized by a third winding 39 disposed on the core 10 in additive polarity to the secondary winding 38 and in such a position as to link with some of the secondary leakage flux but substantially free of linkage with the primary leakage flux, the secondary winding 38, the third winding 39 and the condenser 11 being serially connected. The loose coupling between windings 36, 38 is occasioned by the air-gapped shunts 22, 23 and the air gap 35 tends to isolate the winding 39 from the primary flux which will be substantially confined to the low reluctance shunts 24, 25. The resonant circuit 11, 38, 39 will keep the output voltage substantially constant, the winding 39 being instrumental in neutralizing any harmonics which appear in this voltage. Any slight variations from constancy in the output voltage may be eliminated by the provision of a bucking winding 37 tightly coupled with the primary winding 36 and connected in the output circuit 47, 48. Alternatively, the winding 37 may be dimensioned to give a rising or falling output voltage. Specification 529,420 is referred to.

Filed: 1958-02-21
Abstract: 839,599. Voltage measurement. FIELDEN ELECTRONICS Ltd. Feb. 16, 1959 [Feb. 21, 1958], No. 5673/58. Class 37. [Also in Group XL (c)] A direct-current amplifier comprises a pair of valves with their anodes connected together and to H.T. + and their cathodes connected to H.T. - via matched resistors 8, 9; the grids are also connected to H.T. - via further matched resistors 13, 14 respectively. The cathodes are interconnected by the coil 15 of a moving-coil instrument movement which carries the moving plate 16 of a variable condenser 16, 17. Variation of the capacity due to differences in current through the valves causes a variation in the output current of an electronic oscillator 18, which current flows through resistor 19 to produce a potential drop which, applied to the grid of the first valve in series opposition with the input at terminals 20, 21 tends to maintain the difference between the currents in the two valves zero. The output current of the oscillator, which is proportional to the input voltage, is indicated by a meter 22. The moving-coil instrument movement 15 and variable condenser 16, 17 may be replaced by alternative variable-reactance devices.

Title: Improved lock
IPC: E05B55/00
Filed: 1946-02-25
Abstract: 608,523. Latches. AKTIESELSKABET WITTENBORG'S AUTOMATFABRIKER. Feb. 25, 1946, No. 5878. Convention date, Feb. 24, 1945. [Class 44] In a latch of the kind comprising a latch bolt secured to a tail plate having a slot in which engages a pin on a disc or plate biassed by a spring and turned by means of a knob or key, and in which the pin can retain the bolt in withdrawn position, the slot is so formed and positioned that when the bolt is pressed slightly inwards from the shot position and then released, the pin slips into a branch of the slot in which it will retain the bolt in shot position. The bolt 1 is secured to a plate 4, urged forwardly by a spring 5 and sliding in guides 6. An arm 9 attached to the spindle of the knob or handle carries a pin 8 which works in a slot in the plate 4, the arm being biassed to rotate by a spring 10. The slot comprises portions 13, 14 generally parallel to the direction of travel of the bolt plate, and a part 15 transverse thereto. In normal use, withdrawal of the latch bolt by turning the knob is effected by the pin engaging 'the 'end of the slot 13. If the bolt is pressed right in, into the position shown in Fig. 4, the arm 9 will be rotated by the spring 10, and the pin will move into the part 14 of the slot, this part being curved to correspond to the circular part of the pin, and will retain the bolt in the inner position until the knob is turned to release it. If however, the bolt is pressed in a short distance until the pin is opposite the entry to the transverse part 15 of the slot, and then allowed to move outwardly, the pin 8 will enter the part 15, causing the bolt to be retained in that position. To make the lock reversible, the slots in the plate 4 are made symmetrical about the centre-line, so that the plate and bolt head may be inverted.
