IPC: H04Q9/14
Filed: 1957-09-27
Abstract: 884,295. Electric selective signalling systems. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Sept. 15, 1958 [Sept. 27, 1957], No. 30361/57. Drawings to Specification. Class 40 (1).  In a communication system for transmitting data from a plurality of field stations to a central station each field station has associated with it a particular number and is so arranged that when electric signals representative of this number are transmitted by the central station to all the field stations they are recognized by the associated field station which then transmits its data. As described 30 field pumping stations are divided into two groups of 15 each-the field stations in each group being numbered from 1 to 15-and are selected cyclically in similarly numbered pairs, one from each group, by the central station under the control of a counter. The selection is effected by associating a particular frequency with each group and transmitting, on both frequencies, a series-mode pulse train corresponding to the number registered in the counter. A clock pulse train is also transmitted from the central station on a third frequency. The two selected field stations upon recognition of their identity number, each transmit data and independent clock pulse signals back to the central station on four more frequencies. At the central station received data is staticized and parity checked. If no error is detected the counter is advanced and the next pair of field stations is selected. If a parity error is detected the counter is not advanced and the same pair of field stations is re-selected. After three consecutive re-selections an error indication is produced at the central station and the counter is advanced to select the next pair of field stations. Communication could be via a radio link. Specification 827,008 is referred to in the Provisional Specification.

Title: Improvements in or relating to the conforming of an end portion of a shoe upper
IPC: A43D21/12
Filed: 1937-11-09
Abstract: 505,562. Lasting-machines. BRITISH UNITED SHOE MACHINERY CO., Ltd., RICKS, F., and PRATT, J. W. Nov. 9, 1937, No. 30699. [Class 17 (i)] A machine of the kind described in Specification 461,326 is provided with means movable relatively to the wipers, engaging the upper nearer its edge than the wipers and adapted, by co-operation with a device engaging the inside of the upper, to grip the upper at opposite sides of the toe portion and control it during inward wiping thereof. The coverplate 5 of the wiper box is provided with a slide-way on each side for a bar 11 to the inner end of which is pivoted an arm 15 carrying a pivot 17 for a clamping member 19 of about one inch in height and width. Each slide has spaced bores 27, the inner one being used for men's shoes, to receive a pin on a block sliding in a slot at the end of a lever 29, the two levers being linked to an equalizing lever 37 actuated by a lever 43 for advancing the clamping members to the edge of the wipers or retracting them therefrom. The lever 43 is actuated by the treadle described in the prior Specification, through a lost motion device provided by an intermediate lever 49 having adjustable stops 55 co-operating with an extension 53 of the lever 43. The lever 43 has a toothed segment 109 co-operating with a pawl 107 for holding the clamps in advanced position. On the pivot of the pawl is a member 105 restrained by a link 119 passing through a friction clamp 117 carried by the lever 49, a pivoted stop 131 preventing this from anticlockwise movement when desired. The hand tool co-operating with the clamps has a loop 145 of unyielding wire. In operation, this loop is pressed forwardly into the upper where this projects upwardly around the toe, and the treadle is depressed to commence the upwipe, as described in the prior Specification. Depression of the treadle causes the lever 43 to swing anticlockwise, the clamps 19 advancing to operative position slightly forward of the toe cap line to grip the upper against the loop 145. A friction grip between the treadle and the lever 43 then slips. Meanwhile, the link 119 has swung the pawl 107 into contact with the segment 109, the pawl preventing yield of the clamping members unless the pressure on the treadle is relieved. The upper is clamped while over-wiping, as described in the prior Specification, is performed, the upper being drawn from between the clamping members as shown in Fig. 8. A bracing wire is then positioned, and the work is released, the pawl 107 being retracted as the lever 43 commences to move clockwise in consequence of the relieving of pressure on the treadle. The Provisional Specification refers, also, to Specification 477,429.
Patent GB-652846-A (GB)
Title: Improvements in or relating to telephonic pulse-code-modulation systems
IPC: H03M1/00
Filed: 1948-11-26
Abstract: 652,846. Cathode-ray tubes. PHILIPS ELECTRICAL Ltd., and BAILEY, C. E. G. Nov. 26, 1948, No. 30707. [Class 39 (i)] [Also in Group XL (c)] The decoder in a pulse code modulation communication system is a cathode-ray tube, a deflecting field in which is built up by adding increments of voltage controlled by the elements of a received code combination. In the embodiment described, a threeunit binary code, of " on " or " off " pulses, is used and the tube has three strip target electrodes S1, S2, S3, Fig. 1, to the right of which are seven targets OP. During the receipt of each code combination the cathode-ray beam is scanned from left to right and impinges on one of the plates OP depending on the code combination to send a reconstituted sample signal amplitude to the output lead OT. As the beam sweeps across electrodes S1, S2, S3, three pulses are generated in the lead BV, synchronously with the code group pulse positions and their amplitudes are arranged to be in the ratios 1, 0.5, 0.25 by the attenuator A1, which may be inside the tube. These three pulses, after reversal in valve V2, Fig. 2, are fed to a control grid of valve V3 which is gated on by received code pulses applied, through terminals IT, to another control grid. The weighted negative output pulses from valve V3 are integrated by condenser C6, which is charged through condenser C5 and diode D4. The vertical deflecting plate of the cathoderay tube is connected to condenser C6 over lead YP, so that, following the receipt of the code group, the beam impinges on one of the electrodes OP determined by the code combination. The amplitude of the resulting output pulse is dependent upon the point of the attenuator A2 to which the electrode is connected. The attenuator A2 may be located inside the tube.

Title: Improvements in cooking apparatus
IPC: F24C3/00
Filed: 1929-10-10
Abstract: 336,421. Lambert, F. T. Oct. 10, 1929. Resistance ovens. - An oil jacketed cooker is characterized by the provision of two separatethermostatic control devices, one acting to regulate the heating of the oil to any desired temperature and the other acting either to regulate the flow of oil to the jacket or to regulate the heating of the oil, this thermostatic control being operated by the temperature of the cooking vessel. As shown, the oven a containing shelves c or a removable grating or wire basket, is surrounded by a jacket b enclosed in lagging d. The electric heater j is contained in an external beating chamber h communicating through upper and lower conduits i. i<1> with the jacket. Water for steaming the food may be held in the bottom of the oven, the pipe g regulating the depth of the water and withdrawing grease which may fall thereon. The heater chamber h is connected by pipes l, l<1> to a tube m containing the sensitive element of the thermostat which is regulable by a pointer o working over a dial o<1>. The element is connected by a lever n' to a mercury switch p balanced on a pivot p<1>. The thermostat thus cuts off the current when the temperature rises sufficiently. Alternatively, a variable resistance switch may be used to regulate the strength of the heating current. The variable resistance switch may introduce or cut out resistances in series with the heating element, or it may control the series-parallel connections of multiple heating coils, by means of suitable contacts upon a blade moved by the sensitive elements. A second sensitive element q is placed in a water receptacle r which is warmed after a predetermined time to an extent which operates the thermostat to depress the lever n<1> by the rod q<2> so as to cut off the current. The return of the rod is prevented by a pawl engaging with a stop. The second thermostat may, alternatively, regulate the flow of oil into the jacket which may have an expansion chamber to allow for dilution of the oil when heated. The heater mav be of such capacity as to act as a thermal storage device, in which case the main thermostat prevents overheating.

A bevel wheel 41 fixed to the shaft 40 of the drum 44 meshes continuously with two pinions 53, 54 loosely mounted on a driving shaft 23 either of which pinions may be clutches with the shaft by a sliding clutch sleeve 57 feathered on the shaft and adapted to be moved by a lever 61 pivoted to the cover of the gear-box 31. At its free end the lever is provided with a slot 69 through which takes a pin 70 with a head 71 having an extending arm 72 pivoted to the lever at 73 and carrying a spring 74 which forces the pin to either end of the slot and holds it there. This pin is adapted to be engaged by a striker 75 fixed to the bevel wheel and having an arcuate slot 76 which, during the first revolution of the wheel in either direction shifts the pin from one end of the slot 69 to the other, so that during the second revolution one of the catches 77, 78 will engage the pin, rock the lever and reverse the drum. The lever carries another pin 64 projecting through an arcute slot in the cover of the gear-box, which is shifted by hand from its central position to either side to start the machine. To stop the machine and lock the. lever 61 in its neutral position, a screw 68 in the cover is retracted, leaving a central hole 67 into which a spring-pressed plunger 66 on the lever enters as the lever swings, so as to retain it in its neutral position and prevent the machine being re-started until the screw 68 has been screwed in.

Filed: 1937-11-11
Abstract: 501,082. Looms with automatic weft replenishment. GLEDHILL, W. Nov. 11, 1937, No. 30932. [Class 142 (iii)] In looms wherein during replenishment a full shuttle pushes the empty shuttle upwardly out of the working box a, a spring controlled latch g normally engages a pin h on a spring-controlled arm c carrying a "yielding strip b, which is thus normally positively locked in position to form a rigid top for the box. When replenishment is to occur, a vertical shaft k is rotated, a cam j thereon rocks the latch clear of the arm c, and thus allows the rising empty shuttle to move the strip to the position shown in dotted lines, after which the strip moves downwardly and may help to eject the empty shuttle frontwardly. Two arms c and latches connected by a rod or bar acted upon by the cam j or an arm carried by the shaft k, may be used. A modification is described wherein one or two downwardly extending latches are connected by an arm to the vertical shaft. The usual shuttle binder may be operated from the vertical shaft. The empty shuttle may be removed rearwardly over the box top. According to the Provisional Specification, the yielding strip has horizontal pins movable in vertical guide slots in the box back, depending levers or catches connected by a horizontal slotted bar engaged by an arm on a vertical shaft normally engaging over the pins. The vertical shaft is rotated to disengage the catches &c. and has a slotted connection with the binder lever whereby this is withdrawn simultaneously with unlocking of the box top, whilst moving in and out of the binder during normal working of the loom is permitted.
