Title: Improvements in or relating to electric thermal switches
IPC: H01H37/60
Filed: 1956-03-02
Abstract: 790,961. Thermal switches. COLLIER, R. March 2, 1956, No. 6631/56. Class 38 (5). A thermal switch for controlling the supply of heat to a cooker hot plate comprises a bimetal 16 heated by a coil 17 and carrying a contact 15 which co-operates with a contact 19 on a springy member 18 which is pulled against its bias by a tension wire 20 connected to a terminal 21. The bi-metal 16 pivots about a plate 10 and is connected to a temperaturecompensating bi-metal 11 which follows the surface of a cam 14 so that the position of the contact 15 may be varied. On turning a knob 8 to close the contacts current flows through the wire 20 which expands and so increases the contact pressure. The bi-metal bends to open the contacts whereupon the wire 20 cools and contracts to give a positive opening action. A second switch 21a (Fig. 2) is controlled by a deep notch 24a in the edge of cam 14 and shortcircuits the thermal switch in the " Full " position. Minor notches 24 locate the cam in various positions. Reference has been directed by the Comptroller to Specification 705,918.

IPC: G05G9/08
Filed: 1925-03-11
Abstract: 250,376. Taylor, E. L. March 11, 1925. Controlling variable-speed gearing.-A control lever a is adapted by its lateral or selective movement in a gate p to disengage the main clutch c, to facilitate change. Thus when the lever a is displaced to the left, it strikes directly a swing- ing frame d, the displacement of which through lever h disengages the clutch c. When the lever a is moved laterally the other way, it strikes the upper edge of a medially pivoted plate lever e, which rocks so as to displace the frame d to the left as before. At the end of the gearchanging movement of the lever a, up or down of Fig. 2, the spring of the clutch c reasserts itself to engage the clutch and thrust the lever a back laterally, so that the lever a becomes locked in one of a number of notches s in the middle web of the gate.

Patent GB-958576-A (GB)
Title: Improvements relating to communication systems
Inventor: FLEETWOOD CLIFFORD HENRY JAMES
IPC: H04M9/00
Filed: 1960-02-26
Abstract: 958,576. Direct call systems. HER MAJESTY'S POSTMASTER GENERAL, and ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Feb. 24, 1961 [Feb. 26, 1960], No. 6867/60. Heading H4K. In a communication system in which a master station supplies direct current to extensions to power bi-directional amplifiers at the extensions and controls the direction of amplification at the extensions in accordance with the polarity of the direct current it supplies, at least one further extension is included in the system the bi-directional amplifier of which is powered by a local source while its direction of amplification is governed from the master station by putting earth or battery to the line. The master station can call the further extension, shown to the right of Fig. 1, but cannot control the direction of the amplifier at the extension until permitted to do so by operation of a control switch with contacts K1<SP>1</SP> and K2<SP>1</SP> at the extension. To call the extension the master station energizes relay SW over rectifier Rf which causes earth to be applied symmetrically to the wires L1, L2, to the extension where relay SC operates to connect power to the extension amplifier from the local source over terminals S. The extension-calling relay AC at the master station is connected in the circuit which energizes SC at the extension but if the resistance of the winding of SC is high AC does not operate. Relay AC may be allowed to operate, however, since the value of the resistor R1 it bridges across SW is so high as not to effect the operation of SW. The master station can now talk to the extension but has no control over the direction of the extension amplifier until the extension party operates his control switch to throw contacts K1<SP>1</SP> and K2<SP>1</SP>. Contacts K2<SP>1</SP> connect power to the amplifier without depending on relay SC. Contacts K1<SP>1</SP> connect relay AS in series with AC so that AS operates in response to release of SW as the master station reverses polarity on its line L1a, L1b. Since relay AS acts to reverse the connections of the extension amplifier, polarity reversal at the master station has a talk/receive function. To call the master station from the extension the contacts K1<SP>1</SP> and K2<SP>1</SP> are operated by means of the control switch at the extension to energize the extension amplifier and to energize relay AS at the extension and AC at the master station. Introduction of resistor R1 into the master station loop acts to signal a call and, as pointed out above, the value of R1 is such as not to affect operation of SW. The double wound relay AC may be replaced by a single wound one connected to the centre tap of the directly connected windings Sx1 and Sx2. A two-way amplifier with a D.C. through path may be incorporated in the line L1, L2. The system is otherwise the same as that described in Specification 871,583 except that not all extension amplifiers are powered from the master station.
Patent GB-288791-A (GB)
Title: Improvements in or relating to devices for use on aircraft for dropping bombs or other objects
IPC: B64D1/04
Filed: 1927-03-11
Abstract: 288,791. Ordidge, F. H. March 11, 1927. Dropping bombs.-A number of "firing" levers 11, each adapted to release a succession of bombs, are arranged side by side in conjunction with a " selector " lever 38 and a "check lever 31 for selecting and operating one or more of the "firing" levers. All these levers are pivoted on a spindle 15. Each "firing" lever is connected to its bomb-dropping gear (not shown) by a cable 16, and is norma.lly urged back against a stop 17 common to all the "firing" levers. The "selector" lever 38 has a pair of arms 22, 23 connected by a bridgepiece 24, within which are slidablv mounted plungers 25, one for each " firing " lever. Each plunger has a knob 42 guided in a slot 43, a spring ball catch 44 for holding it in each extreme position, and a notched end 47 for engaging or disengaging behind its lever 11. The "check" lever 31 is carried ,by brackets 29, 30, on the " selector " lever, and is urged radially outwards by a spring 32. A stud 34 on the " selector" lever rides in a curved zig-zag slot 35 in a sector 36 secured to the frame 19 of the apparatus. The stud 34 normally, lies in a locking notch 37 off the slot 35. To put the apparatus in action, the "check" lever is depressed by pressure on its knob 31<a> to disengage the stud 34 from the locking notch 37. The " selector " lever can now be moved forward, and, according to the setting of the plungers 25, will carry with it the selected "firing" lever or levers. Each zig-zag of the slot 35 represents a bomb-dropping stage of the "firing" levers. At the end of a complete stroke of the "selector" lever, the " firing " lever or levers it has operated becomes locked by spring pawls 18, while the stud 34 of the " check " lever passes out of the sector 36 and springs up beyond it. The " selector " lever can now be swung back until the stud 34 is behind the sector 36. The " check " lever should then be again depressed to bring the stud 34 in line with the slot 35, and the " selector " lever moved slightly forward until the stud 34 snaps into the locking notch 37, as in the initial positon. When it is desired to return a " firing " lever back to its original position, the corresponding pawl 18 is depressed, and the released lever springs back to the stop 17. In a modification, a separate " check " lever and notched sector is provided for each " firing " lever. In another modification, the " check " lever is pivoted separately from the " selector " lever to operate a lever for firing sighting or practice bombs, and a screw device is provided to couple the " check " lever to the " selector " lever for operating the main " firing " levers.

Title: Improvements in or relating to baling machine
IPC: B65B27/12
Filed: 1945-03-20
Abstract: 594,422. Baling-machines. ALLISCHALMERS MANUFACTURING CO. March 20, 1945, No. 6948. Convention date, Feb. 28, 1944. [Class 6 (iii)] A baling-machine comprises apparatus which rolls material delivered thereto into a bale of predetermined diameter and then discharges the formed bale, a conveyer for the material, a twine - feeding device to wrap the bale while still in the apparatus, mechanism operative to move the apparatus to the discharge position and then to return it to its initial position, and additional mechanism for controlling and driving said conveyer and twine feeding device, characterised in that said additional mechanism includes a co-acting element and parts operative sequentially to stop the conveyer on the bale reaching the predetermined size and to restart it when apparatus has returned to its initial position. The general features of construction including the bale forming means, bale tying means, twine cutting means and bale ejecting means are substantially as described in Specification 594,421. Conveyer drive mechanism.-The driving connection between the normally rotating shaft 36 and the conveyer comprises a clutch element having a disc 38 of ratchet-like surface 39, an axially extending hub 41 freely rotating on shaft 36 with an external gear 42 meshing with a pair of idler gears 48, each carried on an arm 47, keyed to shaft 36, said idler gears meshing continuously with an internal coaxial gear 52 carrying the sprocket 53. Operation.-The roll portion of a lower drive assembly driven by the shaft 36, and shaft 36 continuously rotate in a clockwise direction, and so the arms 47 and idler gears move bodily in a clockwise direction about the shaft 36. When pawl 55 is engaged with the surface 39, the gear 42 integral with the hub 41 is held stationary, and the bodily movement of the idler gears 48 about the stationary gear 42 results in a clockwise rotation of the idler gears which in turn drive the chain sprocket 53 in the same direction thereby driving the conveyer. When the pawl 55 is disengaged from the surface 39, the clutch element is free to rotate clockwise, but owing to the drag of the conveyer mechanism the sprocket 53 and gear 52 are held stationary, and continued rotation of the shaft 36 merely results in a clockwise rotation of the clutch element. When the bale reaches a predetermined size the latch plate 61 is actuated to move the pawl to a disengaging position, thereby stopping the conveyer.

Title: Improvements in and relating to sewing machines
IPC: D05B29/06
Filed: 1955-03-11
Abstract: 780.893. Sewing machines. DURKOPPWERKE AKT.-GES. March 11, 1955 [March 15, 1954], No. 7151/55. Class 112 A method of sewing together a pair of fabric elements, one of which needs to be gathered or puckered to reduce its length to that of the other as in the sewing of sleeves to the armholes of garments, comprises passing the elements between opposed feeding devices whilst being stitched together, one of said devices having its rate of feed varied, under control of the operator, with respect to the other device without interrupting the sewing process, in order to effect the required degree of gathering or puckering, and the extent of variation between the rates of feed being registered on an indicating device within view of the operator. As shown, the stitching is performed by a needle 21a carried by a vertically reciprocating needle bar 21, and the work passes between a constant-speed feed-dog 1 and a variable-speed feeding- foot 2. The latter is carried by a feed-bar 17 slidably mounted in a frame 15 pivoted at 16 to the machine frame. Reciprocating movement is imparted to bar 17 by conventional means (not shown). Oscillating movement is imparted to frame 15 by means of a sliding connection 14 between frame 15 and a crank 13 carried by a shaft 12, the latter being oscillated via an adjustable eccentric 3 mounted on the driving shaft 4. The eccentric is adapted to be adjusted by movement of a lever 9 connected by a linkage 25, 26, 27 to a treadle or knee press, said movement being limited by studs 21<SP>1</SP>, 22. Lever 9 is also connected by a linkage 28, 29, 32 to a pivoted pointer .33 which moves over a scale 37 to indicate the magnitude of the variation between the top and bottom feeds. A pedestal-like structure 43 carries a curved work support 44. An arm 39 pivoted to a fixed bracket 38 is adapted to be inserted between the layers of material being sewn together in order to prevent pucKering of the lower layer, when sewing with different rates of feed.
