Patent GB-602267-A (GB)
Title: Electronic trigger circuit
IPC: H03K3/10
Filed: 1945-07-25
Abstract: 602,267. Valve generating circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. July 25, 1945, No. 19114. Convention date, June 30, 1943. [Class 40 (vi)] An electronic trigger circuit comprising two valves has one stable and one unstable state of operation and means for applying pulses to the cathode of one of the valves. Fig. 2 shows a multivibrator circuit, valve V1 being non- conducting and valve V2 conducting, in the stable state. A resistance RK1, which may be of high value, is shunted by a rectifier such as diode DI, and connected between the cathode of valve V1 and earth. Valve V1 may be rendered conducting by the application of a negative pulse to the cathode of valve V1 through condenser C, sufficient to overcome the negative grid bias, and normal multivibrator action follows whereby valve V2 is cut-off. The unstable state with valve V1 conducting and valve V2 non-conducting, continues until after a period determined by the time constant of the condenser CH2 and resistor RD2. When valve V1 starts to conduct, a positive voltage is developed across resistor RK1 and diode D1 then starts to conduct, which has the effect of considerably reducing the time constant of the circuit elements associated with condenser C. Thus the duration of the unstable condition of the circuit depends only on the circuit elements CH2, RD2, and may be made independent of the duration or shape of the input pulse, provided only that the duration of the input pulse is shorter than that of the desired output pulse. By this means, rectangular pulses of short duration, of the order of five microseconds, may be produced. The valves V1 and V2 may be in one envelope. The invention may also be used to provide a high impedance tripping or synchronising input circuit by arranging for the resistance shunting diode D1 to be of high value.

Abstract: 934,730. Sawing. JOSHUA BIGWOOD & SON Ltd. July 4, 1962 [May 30, 1961], No. 19397/61. Class 145. A sawing machine for cutting endwise moving stock comprises a saw frame 33 pivotably mounted on a carriage 14 reciprocatable on an elongated bed frame 10, the saw frame being swung in synchronism with the movement of the carriage by a cam 36 and follower 35, one of which is mounted on the saw frame and the other on the carriage. The cam is in the form of a track 36 in one face of a disc 37 mounted on a shaft 38 carrying a gear 40 engaging a pinion 41 in turn meshing with a rack 44 secured to the bed frame 12. The track 36 is engaged by the follower 35 mounted on one end of the frame 33 which is pivotably mounted on a shaft 28 and carries at its other end a circular saw 30 driven by a belt 29 from a motor 27 on the carriage 14. The carriage has rollers 22 for receiving the stock, which may be of U or I cross-section issuing from a cold roll, and a clamp 23 operated by a pneumatic device 26. A latch, which is pneumaticallyoperated, normally retains the carriage adjacent the cold roll and can be released to permit a pneumatic piston-and-cylinder device 18, 19 to reciprocate the carriage. In operation, the stock leaving the cold roll passes through the clamp 23 and on to the rollers 22 until its leading end interrupts a light beam to cause a photo-cell to actuate relays which in turn operate the devices operating the clamp and latch so that the stock and carriage move at the same speed under the control of the pneumatic device 18, 19. During the movement of the carriage, the cam 36 is rotated by the rack-andpinion mechanism 41, 44 to advance the saw at a constant speed into the stock. The saw is retracted from the stock before the carriage reaches the end of its movement which is determined by limit switches directing air to the other end of the device 18, 19 to return the carriage, the cam free-wheeling so that the saw remains retracted until the end of the return stroke and the latch is re-engaged with the carriage ready for the next operation. A tachogenerator may be driven by the saw spindle or motor spindle and have its output connected to a relay such that, in the event of overload of the saw causing a variation in the output of the tachogenerator, the relay is operated to stop the motor driving the rolls of the cold roll advancing the stock and may operate a brake to halt the stock instantly.
