Title: Improvements in control means for flying shears
Inventor: MCTAGGART JOHN
IPC: B23D36/00
Filed: 1962-09-11
Abstract: 1,034,819. Automatic control of rotary shears. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Aug. 30, 1963 [Sept.11, 1962], No. 34697/62. Heading G3R. In a control system for a motor driving the blades of a flying shear, the voltage applied to terminal 39 indicates the length of strip to be cut off, the voltage applied to terminal 41 indicating the periphery of the circle swept by the shear-blades. A signal applied through terminal 49 holds integrating de - vices 33, 37, at zero until a desired starting-point relative to the strip is reached. Tachometer generators 15, 17, provide signals representing the shearspeed and strip-speed respectively,the output of device 37 representing the distance travelled by the strip, and that of the device 33 indicating the distance travelled by the shear blades. A summing device 43 receives inputs from the terminal 39 and the device 37. In summing device 45, the algebraical sum of the inputs to device 43 is added to the input from terminal 41 and the output from device 33. The output from device 45 thus represents the sum of the shear circle periphery and the time integral of the strip speed, less the sum of the desired length and the time integral of the shear speed, the integrals being taken from a datum point given by the making of the previous cut. The output of device 45 is fed to regulator 21 for controlling the speed of motor 13 which drives the blades, thereby enabling the blades to cut off the desired length of material. Potentiometers 14, 36, may be adjusted to vary the ratio between the shear-speed and strip-speed at the moment of contact. In another arrangement, the shears are driven by motor 113 coupled to pulse tachometer 115, a pulse tachmometer 117 being driven by the strip through gear 120. Pulses from the tachometers are fed to counter 129 connected to decoder 133 associated with regulator 137. Terminals 149, 151, serve for the application to the counter of setting signals representing respectively the predetermined length of strip and the periphery of the circle swept by the shear blades.

Title: Improvements in and relating to regulating systems for dynamo-electric machines
IPC: H02P9/10
Filed: 1928-11-26
Abstract: 301,333. British Thomson-Houston Co., Ltd., (Assignees of Park, R. H.). Nov. 26, 1927, [Convention date]. Exciting.-The stability of transmission systems under transient conditions such as sudden loads and short-circuits is increased by so modifying the regulators and exciters of synchronous dynamo-electric machines that, on the occurrence of abnormal changes in the voltage or other characteristic of a machine, the voltage applied to the field of the machine is increased under the control of electromagnetic means to a value several times higher than that required by Ohm's Law to circulate the continuous-rated full-load field-current. The exciting voltage is thus increased at such a rapid rate and to such a value that the machine is maintained in synchronism. In an example where the usual exciter voltage is 250 volts, the armature 6 of the exciter corresponds to a 750-volt machine and the circuit of the field 7 of the exciter is supplied from a separate source 8 and has a low time-constant. A regulator with vibrating contacts 16, 37 shunting a resistance 9 in the circuit of the field 7 is controlled by a solenoid 30 and by polyphase torque motors 18, 33 to provide normal regulation as described in Specification 296,402, [Class 38 (iv), Electric supply and transmission systems &c.]. On abnormal regulator movements resulting from abnormal voltage changes due to short-circuits, contacts 36, 37 are closed and, if a switch 48<1> is closed, energize directly or through a relay a switch 42 short-circuiting a resistance 10 in the circuit of the field 7, a rapid rise in the exciter voltage resulting. A relay separate from the regulator may be used instead of the contacts 36, 37. Excessive current in the circuit of the field 4 is prevented by a switch 51 normally short-circuiting a third resistance 11 and operated to place the resistance 11 in circuit by a solenoid 53 connected in shunt to a resistance 56 in the circuit of the field 4. A fourth resistance 12 is always in series with the field 7. Specification 281,243, [Class 38 (iv), Electric supply and transmission systems &c.], also is referred to. Reference has been directed by the Comptroller to Specification 254,737.

Filed: 1927-12-28
Abstract: 283,134. Telefonaktiebolaget L. M. Ericsson, (Assignees of Laurent, T.). Jan. 4, 1927, [Convention date]. Telephonic repeaters.- Alternating or oscillatory currents from a source S are rectified by being superimposed upon a steady voltage from a D.C. source such as a battery B applied to a condenser C through a discharge device such as a neon tube G having an independent discharge, the steady voltage being below that required to maintain the discharge. The method may be applied to echo-suppression in a telephonic repeater, the rectified oscillations being used for controlling the operation of the relay, e.g. in the case of a thermionic relay E, by imparting additional negative potential to the grid, the circuit of which includes a biassing battery and the condenser C. A resistance leak I is connected across the condenser either directly or through a discharge device to enable the grid voltage to return to its original value when the oscillations cease. A resistance R is placed in series with the discharge device to decrease the rate of charging of the condenser. A discharge device G1, Fig. 3, which discharges continuously at the voltage of the battery B1 may be connected across the latter so that a steady voltage corresponding to the drop across the device G1 is available for application to the rectifier circuit. To limit the voltage of the condenser to a value below that of the D.C. source, the condenser may be shunted by a discharge device in series with a battery.
