Filed: 1927-07-27
Abstract: 291,983. Richards, W. A. R., and Bentley, F. E. July 27, 1927. Turning-gear.-In a device for disconnecting a starting-handle j if the engine turns backwards at starting, a clutch member b is movable axially in the hub w of the starting-handle, by means of a push-rod k, into engagement with a clutch member a mounted on a starting shaft f, which carries a clutch y for engagement with a clutch z on the engine shaft. A sleeve t surrounding the member a is secured to the hub w by an enclosing screw-threaded sleeve r, and pins h on the sleeve t bear against springs q in slots in the face of a ratchet wheel n, which is loosely mounted on the shaft f and engaged by a pawl p in a fixed bracket o. The wheel n is retained in place by a flange m. A semi-circular catch member d is pivoted on a pin e on the clutch member b, and the pin e is adapted to be engaged by a spring-controlled catch c pivoted on the clutch member a. In use, the member b is pushed into engagement with the member a by means of the rod k and is held by the catch c. At the same time, a stop pin in the hub w bears against the end of the catch d and brings it into engagement with a clutch face on the member a. The handle and shaft. f are then pushed axially against a spring x to bring the clutches y, z into engagement, and are turned to start the engine. If the engine turns backwards, the wheel n is held by the pawl p, the shock is taken up by the springs q, and a pin u on the wheel n engages the catch c and releases it from the pin e, whereupon the clutch member b is disengaged from the member a by a spring g.

Title: An improved method of and apparatus for the manufacture of single layer wired glass
IPC: C03B13/12
Filed: 1934-07-07
Abstract: 420,583. Glass manufacture. SCHLESISCHE SPIEGELGLAS-MANUFACTUR C. TIELSCH GES., Altwasser, Waldenburg, Silesia, Germany. July 7, 1934, No. 19950. Convention date, July 11, 1933. [Class 56] Relates to the method of making wire glass continuously in which a band of wire, 14, is passed into a mass of molten glass 1 that flows from a spout into the pass 7 between a pair of forming rollers 4, 5 and is formed into a continuous sheet 8. According to the invention, the wire 14 passes around a guide roller 3 which dips into the molten glass, is provided in its surface with longitudinal or helical grooves, and is so rotated that its peripheral speed is less than that of the shaping rollers 4, 5 or is in the opposite direction. The effect of this difference of speed, and of the grooved surface of the roller, is to cause the glass to penetrate the open spaces between the wires and to be ironed over the wires. The roller 5 can be turned about the axis of the roller 4, and the roller 3 can be adjusted to or from the rollers 4, 5. The pass 2 between the rollers 3 and 4 is wider than the pass 7 so that a reserve supply of glass, 6, forms at the entrance to the pass 7.

Filed: 1936-07-18
Abstract: 475,288. Knitting-machines. WILDT & CO., Ltd., and LEEDHAM, L. H. July 18, 1936, No. 19974. [Class 74 (ii)] Patterning jacks 5 having sliding and pivoting movement in the needle &c. tricks are provided with butts 7 which, when the jacks are selected by pattern cams 20, act upon companion needles or sliders 3. The invention is applicable to independent needle type machines of the circular and flat kinds, and to rib and plain machines having rotary or stationary needle cylinders. As applied to a superposed cylinder rib machine, e.g. as described in Specifications 15008/00, [Class 74], and 24290/12, [Class 74 (ii)], the needleactuating sliders 3 of the bottom cylinder, are operated by the butts 7. All of the jacks 5 are raised by the raising cam 31, but only the selected jacks engage the sliders 3 for actuation of the corresponding needles. For nullifying the patterning effect, the raising cam 31 may be automatically moved from its operative position, or alternatively a cam may be provided for pushing outwards again all the selected needles. This cam acts upon the tail butts 17 of the jacks 5, and where it is desired to knit patterned insteps, butts 17<1>, 17<11> of two lengths are provided, and the outward-movement cam is adjustable automatically so that it either misses both butts 17<1>, 1711, engages only one set of butts 17<1>, or engages both sets.

Filed: 1925-08-10
Abstract: 261,076. Standard Telephones & Cables, Ltd., (formerly Western Electric Co., Ltd.), (Deakin, G., and Polinkowsky, L.). Aug. 10, 1925. Semi-automatic exchange systems.-In a system in which the designation of a wanted line is transferred from a register-controller over a trunk to a call-indicator position at a manual exchange, means are provided by which, in the event of an incomplete number being set up, the manual operator may establish a talking connection to the calling party. The calling line is connected to a link circuit LC, to which a register-controller is connected by means of a finder switch. At the manual exchange the trunk is connected over a finder switch to a register-set, where the registers are set by revertive impulses sent back to the register-controller. If the subscriber has not dialled a complete number, the sequence switch 80 of the link circuit remains in the 9th position, and the registercontroller fails to release. The operator at the call-indicator position presses a key RLK, thereby releasing a relay Prr previously locked up, so that the sequence switch of the register-set is driven to its home position. Switching relay Fur de-energizes. The operator then presses a key RK, which reverses the line current and operates a polarized relay Pol in the registercontroller, and the sequence switch 214 is driven to its home position. Relay 95 therefore falls back and connects up relay 74, which advances the sequence switch 80 to the 14th or talking position. The operator may now converse with the subscriber by plugging into jack LT. A relay Sr serves to disconnect the polarized relay Pol when the fundamental circuit is closed. Specifications 256,544 and 261,456 are referred to.

Abstract: 1,079,355. Fluid-pressure servomotor systems. M. TAKEDA. May 14, 1965 [May 15, 1964 No.20580/65. Heading G3P. Hydraulic control apparatus comprises a spool valve 37 having lands 52, 53 controlling the supply of actuating fluid from a line 27 to a servomotor 22, and lands 54, 56 controlling bleed passages 34, 36 from the chambers 38, 39 at the ends of the spool. The chambers communicate with fluid receiving ports 44, 47 formed in the spool intermediate its ends via longitudinal passages 41, 42 in the spool. The ports receive fluid from a nozzle 13 pivotable in response to variations in a controlled condition. If the nozzle is moved to the right, the additional flow through passage 41 moves the spool to the right to an equilibrium position determined by its co-operation with the bleed passages. When the error is corrected, the nozzle is caused to move to a central position relative to the ports by the reverse, reflex jets acting on its conical head 49. This movement causes a pressure differential on the spool which causes the latter to return to central, neutral, position, the nozzle being forced to accompany this return of the spool by the said reflex jets. A pressure relief valve may be provided in supply line 27. The ports 47, 44 need not cross over, in which case rightward movement of the nozzle would produce leftward movement of the spool. The ports 17, 18 may be shaped so as to provide an initial, narrow, sharp-angled aperture, thereby giving a low piston speed when deviations of the spool are small. The apparatus may be used to control edge alignment in weaving, knitting and printing processes, thickness, width, ratio of mixing of various ingredients, temperature or level.

Abstract: 983,957. Making semi-conductor devices; soldering. SYLVANIA ELECTRIC PRODUCTS Inc. June 7, 1961 [June 10, 1960], No. 20584/61. Headings B3A and B3R. [Also in Division H1] The mounting of a semi-conductor device in the embodiment described starts with a steelrimmed header having three gold-plated Dumet leads of equal length projecting above its upper surfaces. The header 20 is placed in the jig shown in Fig. 3 and the descending punch 34 shears off part of two of the leads 23, 24 and flattens the third lead 25 which rests on an anvil at the base of a slot in the jig. As shown in Fig. 4, the two shortened leads are next given right-angled bends. The process is initiated by dies 40 and 41 operating with die 42 and completed by the latter die and die 43. A 90 degrees bend is next produced in the flattened lead 25, as shown in Fig. 5, by die 50 cooperating with dies 52 and 53 successively. The header is inverted and dipped into tin/lead eutectic solder to coat the three leads and the upper surface 26 of the steel header, and it is then placed in the jig assembly shown in Fig. 7. The semi-conductor device to be mounted consists of a germanic slice soldered across the hole in an annular nickel washer which serves as the base electrode, pellets of lead/aresenic alloy and of lead/antimony alloy being alloyed to opposite sides of the germanic slice to respectively form emitter and collector electrodes. This device is placed on the flat bed 63 of the jig with its alloyed pellets opposite the butt ends 23a, 24a of the two leads and with the nickel base washer frictionally gripped between the flattened end 25a of the third lead and the surface 26 of the header. Operation of the crimping die 66 notches lead 23a near its end, thus extending it into firm contact with the adjacent alloyed pellet and ensuring that both pellets are in contact with their adjacent leads. As particularly described the mounted device is now dipped for 12 seconds in a flux consisting of 1 part by weight ammonium chloride and 3 parts zinc chloride held at a temperature of 300 C. The leads are thus soldered to the base washer and alloy pellets. It is stated that alternatively the mounted device would be passed through a furnace in a reducing atmosphere to carry out the soldering operation. After cooling, the device is etched, cleaned, and baked, and a cap is sealed to the base by any usual technique.
