Abstract: 1,160,745. Shearing. UNITED ENG. & FOUNDRY CO. 8 Nov., 1966 [8 Nov., 1965], No. 47328/65. Heading B3W. A sheet shear comprises a housing, a first knife carried by the housing, a movable knife head to which is secured a second knife, means for supporting the knife head in a position for the knives to co-operate, a first eccentric rotatably carried by the housing and connectable to the knife head for moving the second knife towards and away from the sheet to be cut, a second eccentric discrete from the first eccentric for displacing the second knife out of the cutting position in a direction away from the sheared edge of the sheet and means controlling the movement of the second eccentric in time relationship to the movement of the first eccentric. A mainshaft 13 which has two eccentrics formed thereon is mounted in bearings in the shear frame 11 and worm-driven by a motor 20. The eccentrics are connected by links 22, (23) to a beam 24 which carries a cutter blade 26. A co-operating cutter blade 27 is mounted on the shear frame. The beam 24 is extended rearwards (to the left as seen in Fig. 1) and is connected to a second pair of eccentrics carried on a shaft. Adjacent each eccentric a bell crank 32 is secured to the shaft, one arm of each bell crank being pivotally attached to a respective block 34. Pivotally connected to each of the eccentric links 22 (23) is a strut 36, each strut having a slot 35 to receive one of the blocks 34 and also being connected to an accumulator 38, 39, comprising a piston and cylinder assembly. The piston rods of the accumulators are each connected to one of the blocks 34. The other arms 40 of the bell cranks are engaged by screws 42 (43), the screws being rotatable through screws 48, 49 driven by a motor (50), Fig. 2 (not shown). Operation.-The initial position of the bell cranks 32, is determined by the setting of the screws 42, (43) and the corresponding positions of the eccentrics controls the cutting clearance between the blades 26 and 27. During that part of the revolution of the mainshaft eccentrics which causes downward movement of the cutter 26 the links 36 slide on the blocks 34 so that no rotation occurs of the second pair of eccentrics. During the upward movement of the cutter the links 36 rotate the second pair of eccentrics so that the cutter 26 is withdrawn from the freshly cut edge of the sheet.

Abstract: 1364147 Dielectric storage arrangements KIEVSKY ORDENA LENINA POLITEKHNICHESKY INSTITUT 17 Oct 1972 47842/72 Heading H3B A dielectric store comprises a strip 1, Figs. 1 to 3, of a ferroelectric material such as a lead zirconate-titanate ceramic having piezoelectric properties which are utilized for both reading and writing, the strip being provided on one surface with write electrodes 2 interconnected into parallel rows by jumpers 3, and on the opposite surface having underlying pairs of discharge electrodes 10, 12 interconnected by jumpers 11, 13 into columns of parallel twowire discharge lines, the write electrodes being separated by excitation electrodes 4, 5, 7, 8 interconnected by jumpers 6 and the columns of discharge electrode pairs being separated by screening electrodes 14, 15. In a modification, Fig. 4, each adjacent pair of discharge electrodes are linked by a tellurium semiconductor strip 17 through which current is passed by a power supply 22. Writing is effected by a potential applied from a write signal source to a selected pair of discharge electrodes 10, 12 and to a selected row of write electrodes 2, the imparted piezoelectric stress in the ferroelectric causing an electric charge variation in a sense determined by the applied potential. Reading is carried out by applying a potential between the excitation electrodes 4, 5, 7, 8 and the screening electrodes 14, 15, the resulting piezoelectric stress causing a potential difference to arise between adjacent discharge electrodes 10, 12 which is detected by an output amplifier 21. The capacitive component in the output circuit is removed by provision of the semi-conductor strips 17, a change in the current from source 22 through the strips 17 being produced by a change in concentration of free charge carriers when a read out stress changes the adjacent surface charge of the ferroelectric. In a modification of Fig. 4, control electrodes 24, Fig. 6, are positioned over and insulated from the semiconductor strips 17. Readout through any selected semi-conductor can then be inhibited by exciting the adjacent semi-conductor from a decoder 27 so as to cause carrier depletion.

Filed: 1971-10-22
Abstract: 1415298 Transister circuits; frequency detectors SMITHS INDUSTRIES Ltd 20 Oct 1972 [22 Oct 1971] 49165/71 Headings H3T and H3A [Also in Divisions G1 G4 and H1] A monostable circuit, Fig. 4, comprises: a first control means 56, 60 which allows a capaccitor 26 to charge when it is in a first state (transistor 60 cut of a transister 56 conducting) and which permits the capacitor to discharge when it is in a second state (transistor 60 conducting) ; a second control means 59 which hold the first control means in its first state when the second control means is in a first state (transistor 59 cut off); means 52 for applying an input to both control means to switch them to their first states; and a threshold means 69, 70 responsive to the voltage across the capacitor to change the second control means to a second state (transistor 59 conducting; the first control means changing to its second state only after cessation of the input signal and the change of the second control means to its second state. Application of the leading edge of a negative input pulse at 52 will cut off transistor 59 to initiate an output pulse at its collector and will cut off transistor 60 to allow capacitor 26 to charge. When the voltage across the capacitor reaches a threshold set by threshold circuit 69, transistors 70, 73, 74 switch on to turn on transistor 59 again and terminate the output pulse, this takes place whether or not the input pulse has terminated. At the end of the input pulse transistor 60 turns on again to discharge capactor 26. The monostable circuit is used in a speedometer, Fig. 1 (not shown), the constant width output pulses from it being integrated by a meter which displays the speed, the input to it being a pulse train having a frequency proportional to speed. The arrangement also includes an odometer to which pulses from the monostable are fed via a divider, Fig. 6. Each divide-by-two stage of the divider comprises three bi-stable circuits A, B, C each of which comprises a pair of crosscoupled opposite conductivity transistors, or a a single equivalent PNPN device. Assuming initially that all three bi-stables are non- conducting, the leading edge of a first input pulse will switch bi-stable A to its conducting state and its trailing edge will switch bi-stable B to its conducting state. The leading edge of the next pulse will then switch on bi-stable C to initiate an output pulse and will switch off bi-stable A and B. The trailing edge of the pulse will then switch off bi-stable C to terminate the output pulse.

Abstract: 1,152,055. Brake master cylinders. FORD MOTOR CO. Ltd. 4 Nov., 1966 [20 Dec., 1965], No. 49445/66. Heading F2F. A brake master cylinder, having separate chambers 50, 86 for supplying independently front and rear braking circuits 102, 108, comprises a single piston 26, having an annular area acting on the fluid in chamber 50 and the remaining area acting on the fluid in chamber 86, and a balancing piston 65 arranged in a blind bore 60 in the piston, the inner end of which communicates with the chamber 50 via passages 62 so that pressures in the two chambers act on opposite sides of the balancing piston, there being a trapped spring 74 so arranged that it normally centralizes the balancing piston in the position shown but, should a failure occur in the circuit 108, is arranged to be compressed and allow the balancing piston to move to the end of the blind bore where a conical end face of the balancing piston engages a conical face of the blind bore, the conical face being designed to produce a wedging action to retain the balancing position at the end of the blind bore during subsequent strokes of the piston 26, whereby pedal travel is restored to normal. Should failure occur in the circuit 102, a stem 68 of the piston 65, around which the spring 74 is coiled, is projected by movement of the balancing piston beyond the end of the master piston 26 and so contacts end cap 24 before the end of the master piston stroke. As a result, the loss of fluid in the circuit 108 during movement of the piston 65 is made up towards the end of the stroke of the master piston, since the piston 65 is pushed back into the bore 60, whereby pedal travel is not substantially increased. In order that spring 74 may act to resist movement of piston 65 both ways from its central position, the spring is trapped between a washer 72 held on the stem 68 and a cup member 78 which has an out-turned flange 82 engageable with a shoulder between an enlarged diameter portion 80 and the remainder of the blind bore 60. The cylinder housing 10 is formed with separate reservoirs 12, 14 sealed by a flexible diaphragm 16 and cover-plate 18, and communicating by way of usual ports 52, 54, associated with a trapped seal 44, with the chamber 50 and by way of a tilting valve assembly 88 with the chamber 86, respectively. A seal 58 isolates the chambers from one another.
