Title: Improvements in ingot strippers
IPC: B66C17/14
Filed: 1930-04-23
Abstract: 357,529. Extracting castings. GEORGE, E. J., Route B, Gary, Indiana, and HOWLAND, C. T., 1934, East 31st Street, Baltimore, both in U.S.A. April 23, 1930, No. 12566. [Class 83 (i).] An ingot stripper comprises a stripping mechanism 12 operated by a motor 86 and moved vertically by a motor 73. The motor 73 is first operated to lower the mechanism 12 by means of gearing 74, 68, pinions 61 and racks 59, guided by rails 52 in a casing 10. A counter-balance 9 is simultaneously moved up by other pinions 79 and racks 80. The motor 86 is then operated and acts through gearing 90, 92, 96 to rotate a square shaft 48 which can move axially through the gear 96. The lower end of the shaft 48 engages a square socket 46, Fig. 6, secured to screw member 42 having oppositelythreaded portions engaging respectively a threaded sleeve 16 fixed in the stripper head 13 and a cam 23 sliding in grooves 21 therein. The downward movement of the cam 23 lowers the arms 28 to engage the grips 32 on the mould and further movement causes the push rod 36 mounted thereon to eject the ingot from the mould which has meanwhile been raised from the truck 97. The device is then operated to carry the mould to another truck and lower and release it by reversing the motors 73, 86. If the motor 86 is not stopped when the cam 23 reaches its normal upper position a rod 50 engages the end of the shaft 48 and pushes it out of the square socket, shearing a soft and replaceable metal pin 49 connecting the parts which are covered by a vertically movable dust-cap 52. Lubricant 57 in the bottom of the head 13 is engaged by the cam 23 and is thus carried to the moving parts. Reference has been directed by the Comptroller to Specification 9137/08, [Class 83, Metals, Cutting &c.].

Filed: 1963-03-29
Abstract: 971, 515. Electronic counters. STANDARD TELEPHONES & CABLES Ltd. March 29, 1963 [March 30, 1962], No. 12584/63. Heading G4A. [Also in Division H3] An electronic ring counter comprises a succession of stages each of which includes a twoterminal trigger device in series with a rectifier, the pulses to be-counted being applied to one side of the trigger device, and an output, isolated from any transients in the input, being obtained from the other side of the trigger device. As shown a typical stage comprises a resistor 57, a rectifier 58, a PNPN diode 59 and a further resistor 60. A capacitor couples one side of the rectifier to the opposite side of the rectifier of the next stage so that input pulses from a multivibrator 100 amplified by a transistor 81 advance the counter stage by stage. Operation of a reset key ensures that stage A operates to the first pulse. Subsequent stages produce outputs on leads such as 82 to control links of a telephone system such as described in Specification 971,514 As shown at b in Fig. 7, the outputs are free from transients such as 85 occurring in the input. The outputs may be amplied by a transistor 90, Fig. 2a Fault detecting. The system comprises three like counters 101-103. The outputs of the last stage I in counters 101, 102 are applied to inverter circuits and NOR gates (Fig. 3, not shown) whereby lack of synchronism brings up a first monostable multivibrator. If the fault persists for a predeter. mined time a second monostable multivibrator operates to bring up an alarm circuit and transfer control of the time frame to the stand-by counter 103.

Title: Improvements relating to the electric control and indication of point operating mechanisms for railways and the like
IPC: B61L5/06
Filed: 1934-04-27
Abstract: 431,289. Controlling and indicating the operation of railway &c. points. MACGREGOR, R. M., SHIPP, D. G., and WESTINGHOUSE BRAKE & SAXBY SIGNAL CO., Ltd., 82, York Road, King's Cross, London. April 27, 1934, No. 12760. [Classes 104 (i) and 105] In the electric control and indication of point operating mechanism for railways, &c., of the kind in which the point machine &c., 11 is operated by direct current supplied from the point of control C through a pair of line wires 1, 2 which may also be used for indicating the setting of the points by means of an alternating current transmitted from the points to the point of control, the machine 11 is under the sole control of a polarized single arm control relay 13, 21 located at the points and normally de-energized so long as the position of the points corresponds to that of the point lever &c., 4, any want of agreement causing the relay to be energized so as to supply current to the machine 11. If the lever 4 is moved from normal setting N to reverse R, current will flow from 30 through 7, 2, 14, 13, 15, arm 16 of circuit controller V, segment 17, rectifier 19, line 1, and contact 8 to 31, causing arm 21 to contact 23 and complete a circuit from 30 through 7, 2, 11, rectifier 24, field winding 12, arm 27 of switch UN, 29, 23, 21, 1, 8 to 31. The motor 11 moves the points to reverse, the movement of the points breaking the motor circuit by moving the arm 27, and de-energizing 13 by moving 16, so that 21 returns to neutral position. The field winding 12 is shunted by a circuit including two rectifiers 24, 25 connected to one terminal of the armature 11, and forming a discharge path for the reactive current when the supply to the motor is broken. The setting of the points is indicated at the point of control C by an alternating current circuit comprising a line 3 connected at the point of control through one winding 36 of an indicating relay K to one or other of the lines 1, 2 through the lever contacts 9 or 10 according to the position of the lever 4. At the points there is an indicator controller Y comprising cams 37, 38 operated by the points and adapted to operate movable contact arms 39... 42 which co-operate with fixed contacts 43 ... 46 connected by 47. The arms also co-operate with fixed contacts 48, 49 connected to one terminal of a source 50 of alternating current, and with fixed contacts 51, 52 connected to the other terminal of 50. When the points are at normal, the parts of the controller Y are as shown, so that a circuit is formed from one terminal of 50 through 48, 39, condenser 53, line 1, 9, 36, 3, 40, 51 to the other terminal. When points are reversed, the line 3 is connected to the other terminal of 50, the circuit of 36 being completed through 2 and 54, so that indication of K is reversed.

Filed: 1958-04-22
Abstract: 880,563. Stepping registers. NATIONAL RESEARCH DEVELOPMENT CORPORATION. April 16, 1959 [April 22, 1958], No. 12801/58. Class 106 (1). [Also in Group XL (c)] A two-state circuit comprises two reciprocally coupled transistors TA, TB, Fig. 1, with a feedback loop, comprising a delay line DL and the collector emitter path of a further transistor TF, connected between the collector electrode and the base of one of the transistors TB. The application of a negativegoing trigger pulse to the base of transistor TF causes the collector and base electrodes of transistor TB to be effectively interconnected ; assuming transistor TB is cut off an input trigger pulse causes its base to be sent negative thus causing transistor TB to conduct and the circuit to change its state. A subsequent trigger pulse causes the transistor TB to be cut off once more since while the transistor is conducting its collector electrode is very close to earth potential. The delay line introduces a delay greater than the length of the input pulse whereby potential changes occurring at the collector electrode of transistor TB when a change of state occurs cannot be fed back to the base of the transistor since the transistor TF is rendered non-conducting before the change has time to reach it through the delay line DL. Fig. 3 shows a plurality of the two-state circuits connected in succession to form a shift register with each stage provided with a further transistor TSA, TSB to which the shift pulse is applied. On the application of a shift pulse, potential at the collector of transistor TBB is applied through delay line DLB to the base of the transistor TAA whereby the circuit comprising transistors TAA and TBA take up the state formally held by transistors TAB and TBB.

IPC: H04B3/44
Filed: 1958-04-23
Abstract: 872,000. Automatic current-control systems. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. April 14, 1959 [April 23, 1958], No. 12909/58. Class 38 (4). In a system in which two current-controlled sources supply power to each end of a telecommunication cable, each current regulator is biased to progressively raise its output current when its output voltage falls below half the value normally required to supply the entire cable. The two sources then share the load at the mid-point where the two characteristics intersect, but either source can take over the entire supply without switching. As the two sources are identical only one is described. A saturable reactor CH controls the A.C. input to a rectifier N1 supplying the cable. The reactor CH is controlled by a self-saturating magnetic amplifier MA to maintain the cable current constant, this current being measured by a device REF which may be either a barretter bridge, Fig. 6 (not shown), or a Zener diode bridge with a transistor amplifier, Fig. 7 (not shown), or a magnetic discriminator. The current control winding mcw on the amplifier MA is opposed by a bias winding acw energized by the output of a transistor TR in accordance with the voltage applied to the cable. A Zener diode Z is connected between base and emitter of the transistor so that as the output voltage rises from zero the current in bias winding acw increases, and the output current supplied to the cable falls from a value about 1% above normal down to normal. This is arranged to occur when the output voltage has risen to half its normal value when the Zener diode Z conducts and holds the current in bias winding acw constant despite any further increase in output voltage. Specification 803,641 is referred to.
