Title: Hesitation latch mechanism and electric switch incorporating such mechanism
Inventor: ROBBINS CLYDE FRENCH
IPC: H01H3/04
Filed: 1969-11-14
Abstract: 1,243,104. Releasable fastenings. CUTLERHAMMER Inc. 14 Nov., 1969.[14 Nov., 1968], No. 55875/69. Heading E2A. [Also in Division H1] A three position lever switch with "central off" has pawl catches L, R Fig. 4 which permit a switch operating part LT to move to operate the switch to one position but drop or rise to interfere with the return movement of the part LT at its off position and prevent immediate changeover by inserting a projection as LC between the part LT and a fixed stop LA of the casing. The catches L or R are released only after hand pressure has been removed from the actuator. As appears from Fig. 4 movement to the right of operating part LT, cams catch L upwards at its right hand end to move it clear of pivot LX to an upper pivot point LW whereby an overcentre compression spring LS moves the latch L and projection LC downwards. On reverse (right to left) movement of the operating member LT continued movement beyond the central position is prevented by stop LA and latch LC. The latch L is however moved sufficiently to be engaged with its lower pivot LX whereby release of hand pressure on the member LT allows spring LS to raise the latch L and free the member LT for continued movement to the left. The second lower latch R is symmetrical to latch L and interrupts the continued left to right movement.

Abstract: 1,236,808. Fuelling reactors; radiation absorbing materials. NUCLEAR POWER GROUP Ltd. 19 Nov., 1969 [29 Nov., 1968], No. 56819/68. Headings G6C and G6R. For refuelling purposes the lower part of a charge machine 1 is positioned on the floor 2 of a reactor or other facility to permit transfer of the fuel between openings 3, 4. Since the opposing surfaces of the machine and floor may not be entirely even, radiation may stream through the gaps and to prevent this occurring radiation attenuating members 5, which are compressible, are interposed between the machine and floor. Each member 5 comprises a layer 5a of compressible material, e.g. rubber, and a layer 5b of radiation shielding material, e.g. lead or steel. The thickness of the layer 5b is greater than that of the layer 5a when compressed and the members 5 of successive rows are inverted relatively to one another, as shown, to maintain the shielding effect across the whole width of the space between the machine 1 and the floor 2. In a modification (Fig. 3, not shown), the members 5 comprise successive rows of rings disposed concentrically with the openings 3, 4.

Abstract: 1306030 Automatic phase control system ROBERT BOSCH FERNSEHANLAGEN GmbH 14 Dec 1971 [19 Dec 1970] 57966/71 Heading H3A An arrangement for synchronizing a television camera 1 comprises a control equipment 4 including a phase comparator 5 to which the output of a controllable oscillator 2 in the camera or a signal derived from it is applied along with a reference signal at 13 to obtain a direct control voltage which is applied to control the frequency of oscillator 2 as well as to vary the amplitude of a sawtooth signal derived from the oscillator 2, e.g. via an integrator 16, and applied to a monostable multivibrator 17 so as to compensate for the effect of time fluctuations of oscillator 2 in the multivibrator output 17. In operation a time jitter is caused in the oscillator 2 output by cross-talk between a line carrying the picture signals from camera tube 10 to control equipment 4 and the line 12 carrying the direct control voltage. As the triggering of multivibrator 17 is dependent on the amplitude of the sawtooth at any instant, the control voltage alters the sawtooth amplitude in such a way that the multivibrator 17 is triggered at the correct instant for controlling a deflection generator 8. Fig. 2 (not shown) indicates an integrating circuit for producing the sawtooth wave.

Abstract: 1,211,765. Filter. IMPROVED MACHINERY Inc. 9 Dec., 1968 [29 Dec., 1967], No. 58330/68. Heading B1D. A filter, for thickening wood pulp suspension, comprises a cylindrical perforate drum 11, located in a housing having an inlet 7 and an outlet 8 upstream of the drum and a filtrate outlet 9 downstream, the drum being cleaned by relatively rotating means which induces reverse flow and is followed by means which limits subsequent filtrate flow, to prevent immediate re-clogging of newly cleaned drum surface. In Fig. 2, drum 11 rotates, together with radial partitions 30 which divide its downstream surface, an arcuate baffle wall 24, pivoted at 26 and adjusted at 27, creates reverse flow adjacent outlet 8 by virtue of the drum and baffle wall 24 converging in the direction of drum rotation. A similar baffle wall 34, adjacent inlet 7, diverges from the drum to limit filtrate flow adjacent the inlet. The annular space 42, 10 outside the drum increases in width from inlet 7 to outlet 8 and is so dimensioned that incoming liquid in portion 42 assumes the same peripheral speed as the drum. This construction could be reversed, with outward flow of filtrate through the drum, and partitions 30 and baffle walls 24, 34 located outside the drum. In Figs. 3, 4 (not shown) the drum is fixed, filters by inward flow, and encloses a pair of rotary baffles (83), each of which has a leading portion converging towards the drum, to induce reverse flow cleanings, and a trailing portion diverging from the drum, to limit subsequent filtrate flow. Liquid flow round the outside of the screen may be in the same direction as or opposed to the baffle rotation, openings (85, 86) each serving as inlet or thickened suspension outlet. The baffle 23 in Fig. 2 could be replaced by a nozzle directing reverse flow liquid on to the screen, or both baffles 23, 33 could be replaced by a roller rotating about an axis parallel to that of the drum and having axial slots engaging partitions 30.

Title: Variable mark/space generator
IPC: H03K5/13
Filed: 1978-12-22
Abstract: A system for producing a variable mark/space output signal which has particular application in the driving of a motor for propelling an invalid carriage employs a decoding comparator 5 and a counter 6. The comparator compares a digitally coded input signal 1, 2, 3, 4 with the state of the counter 6 which counts clock pulses 7 continuously. The overflow pulse from the counter sets a bistable 8 while the comparator 5 resets it after the number of clock pulses specified by the input signal. Digital-to-analogue conversion is thus avoided, together with the problems of wear inherent in conventional analogue control systems. The control system which is described derives an output signal of variable mark/space ratio directly from digital signals coded in accordance with a Gray code with a minimum of logic circuitry, and provides the ability to multiplex. <IMAGE>
