Title: Apparatus for performing fabricating operations on sheet material and punch and die members for incorporation in such apparatus
IPC: B26F1/02
Filed: 1972-12-27
Abstract: 1441097 Punch and die mountings E S JOSEPH 27 Dec 1972 [30 Dec 1971] 59722/72 Heading B3W In a pair of co-operating punch and die members, each member has screw threaded means for removably mounting it in a sheet metal working apparatus which mounting means are centrally disposed wholly within the periphery of the member when viewed axially. The punch and die pairs are particularly for use in a press for punching knockouts in sheet metal panels to be formed into, e.g. electrical junction boxes, their mountings enabling them to be placed close together. As shown in Fig. 1 each punch and die has a threaded recess to receive a bolt 66 by means of which it is securable to a template 61 or 62 respectively mounted on mechanicallyactuated platens 57, 58. A central spigot 67 on each punch and die engages a recess in the associated template. Punches 11-13 and dies 16-18 each have an anti-rotation locking pin 69. The spacing between pins 69 and bolts 66 is constant to allow interchange of tools. Punch and die pair 12, 17, for punching a central knockout surrounded by two concentric annular knockouts, comprises punch portions 21, 22 co-operating with apertures in the die 17 in which resilient stripper bodies 34, 36 are located. Relative rotation between punch portions 21 and 22 is prevented by a pin 29. Tabs 39 interconnecting the knockouts are formed by means of notches 40 in the punch portions 21, 22 and die portion 31. To form a central knockout with one concentric annular knockout the die portion 31 and punch portion 22 are omitted.

Abstract: 1387119 Antiskid braking systems AISIN SEIKI KK 23 Dec 1971 [30 Dec 1970 (5)] 60200/71 Addition to 1364476 Heading F2F A digital antiskid brake control system for an hydraulic brake circuit of a vehicle comprises means for sensing wheel rotational speed and producing a pulse signal representing the speed of a wheel or the sum of speeds of more than one wheel, means for counting the pulses in successive time periods and subtracting from the number of pulses in a time period the number of pulses in a subsequent time period, other than that immediately following, to obtain the difference, means for comparing the difference with a predetermined value and means for relieving braking pressure in response to the result of the comparison. Sine-wave signals from wheel sensors are converted into square wave pulses which are fed to the inputs of an exclusive OR gate E1 providing an output fed to a differentiating circuit and to a NAND element M5, the output of which is differentiated and fed with the other differentiated output to a NAND element M6 forming with NAND element M7, capacitor C3 and a resistor R9 a monostable multivibrator, there also being included a clock pulse generating circuit and counters B1, B2 and decoders G1, G2 shown in block II, a computation circuit having flip-flops F1-F37 and NAND elements M15-M21, a pulse difference setting circuit, a pulse difference computation correcting circuit and a pressure reduction signal time controlling circuit shown in block VI and a circuit VII for driving a fluid. pressure reducing valve which controls braking pressure. A predetermined number is subtracted from the difference in pulses to obtain a final number and braking pressure is relieved when that number is positive. The predetermined number is varied in response to actuation of a pressureresponsive switch, the number being higher for braking pressures above a set value than for pressures below.

IPC: H04L27/12
Filed: 1968-12-19
Abstract: 1,248,239. Transistor oscillator circuits; frequency shift modulators. INTERNATIONAL STANDARD ELECTRIC CORP. 19 Dec., 1968 [27 Dec., 1967], No. 60323/68. Headings H3T and H4P. A frequency shift modulator includes an oscillator comprising transistors Q1, Q2 and two long-tail pairs Q3, Q4 and Q5, Q6. Binary data, whose voltage levels lie on either side of voltage E2, switches on one or other pair alternately, dependent on the bit level so that a. current i2 from transformer windings L2 or L3 is added to the collector current of Q1. The current from L2 is 180 degrees with that from L3, and is 90 degrees with the current il circulating in the oscillator feed-back loop. Consequently the oscillator generates alternately shift frequencies which are above and below the frequency of the oscillator when freerunning.

Abstract: 770,700. Laying submarine cables. JOHNSON & PHILLIPS, Ltd., and ASHBY, R. J. Dec. 1, 1955 [Dec. 1, 1954], No. 34784/54. Class 78 (5). A cradle structure 5 for use in submarine cable-laying systems in which the cable 1 passes from the ship 3 over sheave 4 into the sea, the cable being formed with repeaters 2 at intervals, is adapted to receive the repeater and pass therewith round said sheave. As shown, repeater 2 moves forward from the left upon small trolleys 8, 9 until it lands upon cradle 5 supported by trolley 6. The repeater continues to move forward till it engages abutment 12 on the cradle, whereupon rear extension 10 of the cradle is manually pivoted upwards to lock the repeater in the cradle. Additionally, the forward extension of the cradle is manually pivoted upwards and secured by a rope extending between lugs 39, 40 so as to overlap sheave 4. Then the cradle together with the trolley moves forward, the trolley being caught and retained by the sheave guards (not shown) and the repeater together with cradle passing over the sheave. The cradle drops into the sea, to allow the cable with repeater to fall freely behind the ship, the said rope breaking under the stress of the cable so that the cable is guided smoothly by said forward extension into the sea to avoid a sharp bend.

Patent GB-801239-A (GB)
Abstract: 801,239. Rotor balancing. GENERAL MOTORS CORPORATION. June 11, 1956 [July 25, 1955], No. 17938/56. Class 40 (1). In a system for measuring the unbalance of a rotor an electrical signal U obtained from the vibrations thereof is harmonically resolved into two components A and B proportional to U sin # and U cos # respectively (# being an arbitrary angle) and these further resolved into signals related to A cos 0, A sin #, B cos 0 and B sin 0 (where 0 refers to the angular position of unbalance) which are combined to give (A cos # + B sin #) and (A sin 0 - B cos #); the angle # is then adjusted so that the second of these quantities is zero, whereupon 0 = # and the sum (A cos # + B sin #) corresponds to the magnitude of unbalance. Signals from vibration of the rotor shaft 11 (Fig. 1) are split up in the resolver 40 which has a manual adjustment (148) of the angle #. The quadrature outputs are passed to transformers 52 and 52<SP>1</SP> with centretapped secondaries, from which the sum and difference outputs are applied to amplitude- and angle-indicators 92 and 96 respectively. The polarities of the outputs are changed twice per revolution of the rotor shaft 11 by means of relay coils 66, 66<SP>1</SP>, 68 and 68<SP>1</SP> operated by cams 106 and 108 driven from shaft 11. Coils 66 and 68<SP>1</SP> are controlled by cam 106 and coils 66<SP>1</SP> and 68 by cam 108 spaced 90 degrees from 106 on the shaft 102. By operating the control 148 until the indication of 96 is zero the reading of 148 gives a measure of the position of unbalance # and the reading of 92 indicates the magnitude of unbalance. If the rotor to be balanced is axially elongated two pick-ups are used with two separate sets of apparatus or with the same one connected to the two in succession. In the case of a belt-driven machine (Fig. 11) the reference point from which the angle # is measured is a white spot from which light is reflected to a photo-cell 179. The pulse from the latter triggers a sawtooth generator whose output is shaped by the usual circuitry to give two square waves in appropriate time-relationship for operation of the relay coils at XX and YY. In an extension of the system (Fig. 10) the amplitude signal is applied via line 190 to a servo amplifier where it is compared with a D.C. standard 196. The resulting error signal actuates a servomotor 200 which controls an attenuator 32 to reduce the amplifier input; the setting of the attenuator then gives a measure of the amplitude of the rotor unbalance. A further servo system 204, 206, 208, 211 may actuate a device 212 such as a driller or welder to remove the unbalance from the rotor. The shaft is rotated via a similar servomotor 222 (driven by the phase signal) so that the device 212 operates on the rotor in the correct position determined by the angle #.
