Abstract: 1,149,519. Photo-flash apparatus. WEST ELECTRIC CO. Ltd. Nov.23, 1966 [Nov.24, 1965 (6)], No.52503/66. Heading G2A. A photo-flash apparatus has means for mounting both a single flash-lamp and a flash-cube. As shown, a single flash-lamp 4 may be mounted in a socket 7 in a rotatable 2 wherein it is held by spring-biased electrical contacts 8, 9 against the force of an ejector 12. In use the lamp and member 2 are rotated anti-clockwise through 90 degrees against the force of a spring 15 to a position wherein the member 2 is held Fig. 6 by the engagement of a recess 16 thereof with an arm 20a of a pivoted member 20 and the lamp is held adjacent a reflector 3 and is connected in a firing circuit having a battery (45), a capacitor (C) and a test lamp (T), Fig. 10 (not shown) by engagement of arms 8a, 9a of contacts 8, 9 with contacts 17, 18. The flash-lamp may be tested before firing by further anti-clockwise rotation whereby a projection 36 on member 2 closes contacts 43, 44 of a switch (S2) causing test lamp (T) to light if the flash-lamp is good. After the flash-lamp has been fired by closing a switch (S1 in the firing circuit, it may be ejected by depressing a knob 29 which engages an arm 20b of member 20 releasing the member 2 and flash-bulb which are rotated to their original positions by spring 15; further depression of knob 29 causes arm 20b to pivot the contact 9 to release the flash-lamp which is ejected by member 12. A flash-cube 5 having radial projections 24 and contacts 40 may be mounted in radial slots 25, 22' in an abutting rotatable members 6, 26 mounted on member 2. In use the flash-cube is rotated clockwise with member 26 against the force of spring 15 so that radial lugs 27a, 27d, 27c on member 26 successively kick a hook shaped end 19a of a pivoted member 19 which is integral with member 20 until further rotation is prevented by a projection on lug 27d abutting a stop 39. The flash cube is then released, whereby it is rotated counter-clockwise by spring 15 until it is stopped by lug 27c engaging hook 19a, in which position Fig. 8 the flash-cube is connected into the firing circuit via a pair of contacts 41, 42 in parallel with contacts 17, 18. On depressing switch (51) one bulb of the flash-cube is fired together with the flash-bulb 4, if any, operatively mounted in socket 7. After firing, knob 29 is depressed to pivot member 19 whereby lug 27c is released from hook 19c and the flash cube and member 26 are rotated by spring 15 until lug 27a engages an arm 19b of lever 19. On releasing knob 29, member 19 pivots back to release lug 27a so that the flash cube again rotates until lug 27d is engaged by hook 19a, whereby the next bulb in the flash cube is ready for firing. This sequence of firing and rotation is continued until all the bulbs in the flash-cube have been fired and further rotation of the cube is prevented by lug 27d abutting stop 39. Reference has been directed by the Comptroller to Specification 1, 034, 909.

Title: Weight sensing cell
IPC: G01G3/16
Filed: 1971-11-15
Abstract: 1369035 Gain control FRANKLIN ELECTRIC CO Inc 15 Nov 1971 [16 Nov 1970] 52907/71 Heading H4R [Also in Division G1] In an apparatus for sensing a weight or force W arranged to stress a vibrating member 36 the change in vibration frequency caused by application of the force is sensed photoelectrically to produce a signal representative of the force.  In a weighing machine a weight placed on a pan (20) is converted into the force W by a bracket/flexure-linkage arrangement (32, 28, 29), Fig. 2 (not shown). The loading cylinder 38 is connected to two pre-tensioned metal strings 36, 37. As shown the vibration frequency of the upper string provides the output 57 to a computer which is calibrated in frequency v. weight. The upper string vibration frequency is also compared with a standard frequency in a mixer 54 and the difference frequency is supplied to a comparator 56, which also receives the lower string vibration frequency. If the frequency difference between the two comparator inputs is above a pre-set level a feedback signal is fed to a servo 39 to alter the pre-tension in the two strings to maintain the frequency v. weight relationship a linear one. In each photosensing arrangement a light source (182) incorporating a lens (184) illuminates a slit (193) adjacent which the string 36, is vibrating (Fig. 8, not shown). The modulated light beam is received by a photodiode (189). Each string is induced to vibrate at its natural frequency by a core (168) in a coil (167). Passage of A.C. current through the coil sets up a magnetic field in the core and the string, causing the latter to vibrate at its natural frequency. Control circuit.-The circuit of Fig. 12 is used to limit the amplitude of the string vibrations. The output of the photo-cell 189 is amplified at 203 and passes through a photoresistor 207 before being applied to the coil 167. Fluctuations in potential across the coil appear on line 208 and are rectified 211-216 to provide a D.C. signal for a lamp 217. This lamp is close to the photoresistor 207 and provides a feedback loop therewith for regulating the current through the coil 167.

Title: Data processing systems incorporating microprogrammed auto matic control means
IPC: G06F9/46
Filed: 1973-11-16
Abstract: 1446740 Data processing system INSTITUT FRANCAISE DU PETROLE 16 Nov 1973 [27 Nov 1972] 53429/73 Heading G4A A microprogrammed data processing system including a number of peripheral devices is arranged to execute tasks relating to two types of operation, viz. data transfers to and from the peripherals and ordinary computation, and includes a scheduler arranged to establish and maintain for each type of operation a list of tasks awaiting execution and to cause the highest priority waiting task to be executed. General.-A computing unit 15 executes tasks under the control of a microprogram control unit 1 which includes read only microprogram memories, a general microprogram unit 16 controlling scheduling and other processes common to both types of operation, and two units 161, 162 controlling processes specific to respective ones of the two types of operation. The computing unit 15 is associated with a read/ write memory, an ALU, and various registers including status registers 5. Scheduling.-A unit 18 establishes and maintains, for each type of operation, an ordered list of tasks which are ready for execution. Unit 18 controls status registers 20, and 21, the latter indicating for each type of operation whether a task is awaiting execution, and the former indicating whether a change in the state of register 21 was as a result of a task associated with the higher priority one of the two types of operation becoming available for execution. Whenever register 20 is triggered by unit 18 control is transferred to unit 16 which tests register 21, and transfers control to unit 17 which interrupts the task currently being executed, saves status and other data to enable the interrupted task to be resumed, in response to the state of register 21, transfers data associated with the task at the head of the appropriate list in unit 18 to registers in the processing unit 15 to enable the task to be executed, and sets flip-flop 19 whose two states correspond to the two types of operation to indicate which type of operation is currently active. Control is then transferred to unit 16 to cause the task to be executed. When the task has been executed unit 17 saves data associated with the new task and transfers the previously saved data associated with the interrupted task to the processing unit to resume that task. A modification is illustrated in Fig. 3 (not shown), involving four types of operation, there being four microprogram units corresponding to units 161 and 162 for the four types and registers 21 and flip-flop 19 having additional states.

Abstract: 1,213,471. Agitating by ultrasonic vibration. JOSEPH LUCAS (INDUSTRIES) Ltd. 26 Jan., 1968 [17 Feb., 1967; 18 July, 1967; 5 Sept., 1967; 27 Nov., 1967], Nos. 7698/67, 32996/67, 40536/67 and 53780/67. Heading B1C. [Also in Divisions H1 and H4] A battery plate for a lead-acid battery is manufactured by supplying a non-flowable lead-acid battery paste to one face of the plate grid and then subjecting the paste to vibrational energy, causing it to flow into the interstices of the grid. In a particular embodiment the grids, each up to 1/4 inch thick, are pasted in pairs each pair being joined together at their bases and lying flat with their lugs pointing outwards. The grid pairs 21 are initially transported through the apparatus on conveyor 22, the grids travelling on rails and being drawn along by chain driven fingers which engage their lugs. The paste is mixed in hopper 23 and extruded from nozzle 39, the continuous strip of paste being cut into sections by rotating wire cutter 41. Ultrasonic oscillator 25 is driven by transducer 54 through velocity transformer 52. Block and pad 57 and 58 are of rubber and bush 59 is of PTFE. The oscillator is cooled by water flowing in at 62 and out at 64. The oscillator dips into the paste on the grid and oscillates at a frequency up to 24 kc/s. and an amplitude of 0.0001-0.01 inches. Its lower surface is inclined at 30-45‹ to the grids. To paste a pair of grids 4 oscillators are used side by side with P.T.F.E. shims in between. Flexible grids are supported by steel bar 24 whilst under the oscillator. The bar is supported on a mounting block (Fig. 3, not shown) which may be heated to 120-200‹ C. by steam passed through it. The support has channels in it to allow some of the paste to pass through the grid to the underside. The gap between the oscillators and support may be closed at the ends by guide plates (82, Fig. 3) which prevent spillage sideways. The upper surface of the pasted plates is smoothed by doctor blade 72 and the plates then pass through sensor 73 which actuates invertor 74. The invented grids are again subjected to oscillation at 28 and smoothed at 75 before entering drying oven 29. Inventor 76 also brushes surplus paste from the edges of the grid pans before they are separated at 85. In a modification (a) a second paste hopper may be present between invertor 74 and the oscillator 28 to paste the second side of the plate (b) the conveyors may be of sprocket type engaging perforations made in special battery grids and (c) the two oscillators corresponding to each plate may be inclined to give thicker pasting in the middle of the plate.
