Abstract: 1276554 Variable speed gearing R R SMYTH W B SMYTH and J A LAHIVE Jnr 15 Aug 1969 40887/69 Heading F2D  A variable speed transmission comprises an intermediate shaft 17 connectable (e.g. via a clutch 20) to a source of power 21 and to an output shaft 18 via a selected pair of meshing gears G2 and G11, G3 and G12, G4 and G13, a comparator (e.g. a differential amplifier 72, for sensing the relative speeds of the shafts 17 and 18 via transducers 55, 56, converters 70, 71, biasing one speed according to the desired ratio by a switch 90) providing signals B, C to a control device 59 (e.g. flip-flop circuits 79, 81 and solenoids 85, 83) to control a brake 47 and a drive means (e.g. an electric motor 50 or a friction clutch between the gear G4 and the shaft 18) to bring the relative speed to within a predetermined range, the control device 59 being operative only when the shaft 17 is disconnected from the source 21. The control device 59 may either light a lamp visible by the driver of a vehicle comprising the transmission, or form part of an automatic transmission, Fig. 4. In this, when the factored speed of the shaft 18 falls outside a chosen range, a signal is supplied from pulser 101 or 102 to a coil 115 or 116 to step up or down the switches 90, 110 and the gear ratio, and also a signal via the flipflop circuit 105 disengages the clutch 20 closing a switch 52, and de-energizes a flip-flop circuit 120, relays 125 ... 128 hence via an inverter 150 and AND gates 107, 109 enabling the signals BC to control the solenoids 83, 85. The clutch 20 is kept disengaged during a gear shift by signals B or C being supplied via an OR gate 104 to the circuit 105. At the end of a gear-shift the signals BC are negligible, OR gate 104 is deenergized, an inverter 118 re-energizes the circuit 120, the selected relay 125...128 and its switch S125...S128, removing the signal supplied from the inverter 150, enabling an AND gate 151 to supply a signal to circuit 105 to re-engage the clutch 20 opening the switch 52.

Title: Improvements in or relating to weighing machines
Inventor: ASHWORTH ERNEST FRANKLIN
IPC: G01G23/16
Filed: 1958-12-29
Abstract: 901,840. Weighing apparatus. ASHWORTH Ltd., E. & A. March 18, 1960 [Dec. 29, 1958], No. 41838/58. Class 143. In a weighing machine of the type in which weight is indicated by the movement of a pointer over a scale and in which the scale is itself movable for zeroizing purposes, means are provided to produce a manually-initiated but automatically controlled operation of the zeroizing process. The invention is applied to the filling containers whose tare weight must be discounted and the control means is electrical. As shown, the spindle of the pointer 11 carries a circular disc 13 in whose periphery is a slot 14 which moves with the pointer, the disc normally serving to cut off the light between a lamp 16 and a photo-cell 15. When the pointer has responded to the weight of the container an operator switches on the motor 26 which, by drive cord 23, rotates the annular member 21 on which the lamp and cell are mounted until the slot 14 allows the cell to be illuminated. When this occurs the cell triggers a thyratron to operate a relay which switches off the motor. Material subsequently fed to the container causes the pointer to advance over a graduated scale which is carried by the member 21 and whose zero coincides with the cell 15. The feed may be by a conveyer or from a valveclosed supply source and may be automatically cut off by further photo-cells 17, 19, one of which is operated by the slot 14 to slow the feed rate and the other to finally cut off the feed. When the weighed load is removed from the scale the motor 26 may be used to return the member 21 to its original position controlled either manually or by the return movement of the pointer. Alternatively, the member 21 may be held in the position to which the motor originally advances it by detent means engageable in holes as shown in the member, the return movement being achieved under the action of a spring 27 on release of the detent. The Specification also discloses a relay circuit (not shown) by which the automatic taring, feeding and resetting operations are controlled and which includes provision for preventing the commencement of feed should the tare weight exceed a predetermined maximum and which also lights signal lamps indicating each stage of the sequence of operations.
