Patent GB-826555-A (GB)
Title: Improvements in or relating to a control circuit employing semi-conductor devices
Inventor: JR JOHN CLARK SIMS
IPC: H03K3/33
Filed: 1957-01-25
Abstract: 826,555. Circuits employing bi-stable magnetic elements. SPERRY RAND CORPORATION. Jan. 25, 1957, No. 2840/57. Class 40 (9). [Also in Group XL (c)] In a circuit comprising a saturable core T2 biased by current in a winding 50 to a saturated state, a further winding 46 is connected to a series of semi-conductors 40, 41 and 42, current due to charge carrier storage set up by input signals at terminals 52, 53 or 54 being supplied through the semi-conductors to drive the core into an unsaturated region. A square clock pulse waveform A is applied over terminal 47 and isolating diodes 43, 44 and 45 to the diodes 40, 41 and 42. During the negative-going waveform diode 43 is reversely biased and no current flows in winding 46, and in the succeeding positive-going wave a small current passes through the back resistance of diode 40 to cause a small current in the winding but since this is insufficient to drive the core from its saturated state, no output appears across the winding 48. If, during the next negative-going clock pulse an input pulse is applied to the junction of diodes 40, 43 forward current flows in diode 40, driving the core further into the saturated region. When the input pulse ceases and the clock pulse reverses, considerable current flows in the reverse sense of diode 40 driving the core from one saturated condition to the other, Fig. 3 (not shown), to produce an output pulse on winding 48. This output pulse is terminated by the next negative-going clock pulse which allows the bias source to restore the core to its original condition. The input signal may be applied over a transformer, Fig. 1 (not shown), and blocking pulses applied to the secondary to prevent reaction on the input due to clock pulses. The circuit may be regarded as an OR gate since when any one of the diodes 40, 41 and 42 is rendered conducting an output appears on winding 48. A winding 55 is biased from a battery 56 so that the output is at battery potential except in the case when an output appears across winding 55. In this manner the circuit may be regarded as an AND gate since only in the absence of any input does the output correspond to the battery 56. The circuit may be arranged so that more than one rectifier 40 must be energized before an output occurs. Specification 826,556, [Group XL (c)], is referred to.

Title: Improvements in and relating to the manufacture and production of tubular bodies from viscose
IPC: A22C13/00
Filed: 1933-01-30
Abstract: Tubular bodies, particularly sausage casings, prepared from viscose are allowed to rest for several hours between the washing and desulphurizing treatments, the tendency for the evolution of gas inside the tube being thereby reduced.  A rest period of from six to twelve hours is proposed, and preferably the tube is allowed to remain in water during this period.

Title: Improvements in or relating to vehicle direction indicators
IPC: B60Q1/36
Filed: 1947-01-30
Abstract: 635,071. Road-traffic signals on vehicles. O'SHEI, W. E. Jan. 30, 1947, No. 2857. [Class 118 (ii)] In an electricallyoperated vehicle ' direction-indicator in which a switch is mechanically operated when the signal arm is displayed to reduce the current consumption, the switchactuating member has magnetic means to ensure positive operation to the position in which full current is supplied (if, for example, a biassing spring becomes weakened). In the construction shown, comprising a signal-operating solenoid with two windings 5, 6, the switch comprises a contact member 10 urged by a leaf-spring 13 towards the earthed bracket 3. Contact member 10 carries a magnetic pin 11 enclosed in an insulating sleeve 12 adapted to project into the core tube 4. When the common solenoid terminal is connected into circuit the pin 11 is mag- 'netically actuated to ensure closure of the switch and both windings are energized. On full actuation of the core 7 the switch is opened to disconnect coil 6. Instead of using the operating solenoid or magnet the switch may be controlled by a permanent magnet or a permanently-energized electromagnet. Specifications 435,803 and 635,067 are referred to.

Title: Improvements in and relating to a fin arrangement for projectiles
IPC: F42B10/20
Filed: 1959-01-29
Abstract: 846,069. Self-propelled missiles and tail units therefor. HOTCHKISS-BRANDT. Jan. 29, 1959 [Feb. 13, 1958], No. 3167/59. Classes 9(1) and 9(2). A tail unit for a missile as described in Specification 768,295 comprises an annular body 1 screwed on to the nozzle e and provided with pairs of bosses 4, 5 between which are pivoted fins 3 held in the folded position by cranked arms 28 mounted on a tube 25 containing a launching charge as in Specification 768,295. The tube 25 is screwed to a plug 22 held in the body 1 by shear pins 23. When the charge 26 is fired the gases enter passages in the plug 22 and through passage 27 may fire a device f as in Specification 768,295. The gases also cause the pins 23 to shear, so that the plug 22 and tube 25 are left behind in the launcher and arms 28 leave the fins 3. The propellent gases also enter cavities 8 between the fins and the body 1 and the outward thrust of the gases forces the fins to the extended position. As the fins rotate a heel portion 14, Fig. 6, stresses a locking spring 17 and when a bearing surface 12 comes to rest against a lug projecting radially from the body 1, the spring becomes wedged against a curved surface 15. The medial plane of each fin is inclined at a small angle to the axis of the projectile, so that in flight each fin has a positive incidence to the relative wind and thus produces a rotation of the projectile. Also the pivotal axis of each fin is inclined at a small angle to the projectile axis, so that when in the closed position each fin has a slight positive incidence to the launching gases on the outer surface. Thus a component of the gas thrust opposes the thrust of the gas in the cavities 8 and slows down the deployment of the fins. When the projectiles are to be used with lowpowered propellants, the locking spring is reduced in size and carries a weight to support the deployed fin.

Abstract: 469,898. Thermionic valve circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and FALLOON, S. W. H. W. Feb. 3, 1936, No. 3273. [Class 40 (v)] A pulse generator comprises a valve 1 backcoupled over a transformer 5, whose secondary is connected, at one end, to the grid over a resistance 9, and at the other end to a condenser-resistance combination 11, 13. The condenser 11 is charged by grid current until the bias so produced renders the valve non- conducting, the charge then leaking off over resistance 13 to allow the valve to conduct again. Variation of resistance 9 controls the length of the conductive periods. The transformer windings may be damped by resistances 7, 12. The pulses may be used to key a transmitter, e.g. a direction finding pulse transmitter. The anode of valve 1 is directly connected to the cathode of valve 15, the grid of which is biassed from the source 6. When valve 1 is conducting, the potential difference between grid and cathode of valve 15 is such as to allow valve 15 to conduct. The current through resistance 14 similarly allows valve 20 to conduct, so that valves 19 and 20 then short-circuit the resistance 23 thus allowing valve 27 to oscillate. When valve 1 is blocked, valves 15, 20 are also nonconducting and valve 27 is prevented from oscillating by the bias developed across resistances 30, 23.
