Title: A buoyancy control system
IPC: B63G8/22
Filed: 1966-10-12
Abstract: 1,110,630. Buoyancy control system. BLUE MERIDIAN CO. Inc. 12 Oct., 1966 [22 Oct., 1965], No. 45691/66. Headings B7A and B7M. The volume of the air space within the free-flooding buoyancy chamber 10 of a buoyancy control system is controlled by the adjustable water level sensing means 22 which is electrically connected to an air supply means by cable 30 and causes air to be introduced into the chamber 10 through air lines 14a, 14b and inlet ports 10a, 10b when the water of the air-water interface of the air space within the chamber contacts the water level sensing means 22. Opening 15a of a vertically adjustable pipe 15 provides fluid communication between the interior of the chamber 10 and the surrounding water and as bar 20 fixed to pipe 15 adjustably supports the water level sensing means 22 which is fixed to platform 24, vertical movement of pipe 15 by handle 16 decreases buoyancy by allowing air to escape when the air-water interface of the air space within the chamber is at or below opening 16a and increases buoyancy by causing air to be introduced when the interface is at or above the water level sensing means. Fig. 3 (not shown) illustrates the buoyancy control system attached to an anti-shark cage. It may also be part of a mine or warhead or be attached to a submarine observation platform or prospecting device.

Abstract: 1481548 Automatic voltage control COMPAGNIE INTERNATIONALE POUR L'INFORMATIQUE 23 Oct 1974 [23 Oct 1973 20 Aug 1974] 45968/74 Heading G3R [Also in Division H2] A regulated D.C. voltage supply circuit includes a bridge of high frequency switched transistors, with one diagonal connected to a D.C. source and the other diagonal feeding an output transformer. Switching control circuits receive signals from a clock pulse generator such that adjacent transistors are switched in phase opposition through transformers. One transistor in each opposed pair is switched on for a time dependent on a comparison of an output voltage error signal and a sawtooth signal. As shown in Fig. 1, a battery B is connected across a transistor bridge Q1-4 supplying an output line 50 over a transformer T5. The output voltage is compared with a reference voltage V2 in a potentiometer 51 and operational amplifier AE feeding an error output signal to a comparator ACA which also receives a sawtooth signal (9) derived from a clockpulse generator TG over an integrating circuit Int. The output of the comparator ACA is fed to two NAND gates El, E2 which receive other inputs derived from the clockpulses and serve to control the switching of transistors Q1, Q2. Two other NAND gates E3, E4 control transistors Q3, Q4 solely in accordance with the clockpulses. The NAND gates and transistors are connected by way of inverters I1-4 and control transistors 91-94 in series with the primary windings of switching transformers T1-4, the secondary windings of which are connected across the transistors Q1-4. The switching is such that transistors Q3, Q4 are turned on alternately with only a short guard interval between them, and transisotrs Q1, Q2 are turned on respectively during the conductive periods of transistors Q3, Q4 for periods dependent on the signal from comparator ACA. The value of the voltage error signal is limited by a circuit responsive to the current in transformer T5 as measured by a transformer T6. In modifications, resistors are connected in series with the transistors Q1-Q4, Fig. 3 (not shown), and parallel transistor groups may be used, Fig. 4 (not shown), to minimize unbalance in the bridge.

Abstract: 1,236,379. Grinding; shaping metal; indexing. RALEIGH INDUSTRIES Ltd. 21 Jan., 1969 [21 Oct., 1967], No. 47977/67. Headings B3B, B3D and B3L. A method of generating a channel of semicircular cross-section in a workpiece, such as a die, comprises reciprocating the workpiece relative to a cutting or grinding tool, and simultaneously moving the workpiece in an arc. The method may be carried out in a shaping or grinding machine having a tool 15 or wheel 16, Fig. 1, the workpiece 17 being indexed through positions A,A, B,B . . . G,G as it is reciprocated so that the tool or wheel forms a semicircular channel 18 in the workpiece. The opposite ends of the workpiece may move in arcs of different radii so that the channel is tapered. In apparatus for carrying out the method, the workpiece 17, Fig. 2, is secured by clamps 34 to a support 26 mounted at its ends on spherical bearings 38 on crank-pins 31. The latter are carried by slides 30 adjustable by screw 32 along guideways in members 29 secured to coaxial trunnions 28 mounted in brackets 27 on a base 25. Gauge blocks 37 may be used to determine the positions of the crank-pins and thus the radii of curvature at the ends of the semicircular channel formed in the workpiece. The trunnions 28 are connected by gearing 51, 52 to a shaft 50 connected by worm gearing 48 to an indexing mechanism for incrementally rotating the trunnions 28 and hence moving the workpiece in an arcuate path during reciprocation of a carriage supporting the base 25 relative to the cutting tool or grinding wheel. The support 26 and workpiece 17 are prevented from rotating about the axis of the crank-pins during their arcuate movement by slide blocks 42 which engage hardened faces 43 in the support 26 and are mounted on pillars 40 carried by slides 41 movable along transverse guideways in the base 25. The indexing mechanism comprises a shaft 47, Fig. 8, which in addition to the worm 48 is keyed to an indexing gear 46 and rotatably carries a sleeve 55. Indexing gear 46 is engaged by a reversible pawl 63 connected to the sleeve 55 which carries rotatably mounted pulleys 56, 57 selectively engageable to the sleeve by a slidable clutch member 58. Each pulley has a cable 64, 65 wound round its periphery and extending out of the housing of the mechanism, and further spring loaded cables 68, 69, Fig. 6, act on pulleys 66, 67 to return the pulleys 56, 57. The mechanism 45, Fig. 9, is mounted on the reciprocating table of the machine and a rail 75 moves with the table and carries a slide rail 77. The cables 64, 65 are secured to a carrier 78 on the rail 77 and towards the end of the movement of the table, the carrier engages a stop 80 to hold the rail 77 while the table of the machine continues to the end of its stroke, the further movement causing the cable 64 or 65 to index the workpiece through part of its arcuate path in one direction or the other. Retraction of the clutch 58 reverses the direction of indexing.

Title: Priority polling systems

Filed: 1966-11-02
Abstract: 1,143,507. Input/output control. INTERNATIONAL BUSINESS MACHINES CORP. 2 Nov., 1966 [29 Dec., 1965], No. 49047/66. Heading G4A. In a priority polling system for selecting one of a number of stations, each station in a demand state responds to a polling signal to emit a return address signal comprising an ordered plurality of parameters unique to that station, a polling signal being initially issued to each station, parameters of greatest significance in each order in turn of any return address signals being selected, each selection preventing issue of a polling signal to those stations not corresponding to the selected parameters, so that after all orders have been considered one station is finally selected. A data-processing system comprises four address circuits, each feeding a respective set of n lines, the 4n lines serving to address (i.e. select) input/output units. Each input/output unit receives one line from each set, concurrent energization of all these four lines selecting the unit. A ring counter at the data-processing system, when activated, controls the. following sequence of operations. Firstly, all 4n lines are energized simultaneously, so selecting all the input/output units. Those input/output units which require service return their addresses simultaneously to the data-processing system on four further sets of n lines, each unit being permanently connected to one line from each set for this purpose. Each of these further sets of lines goes to a respective one of the four address circuits. The ring counter enables each address circuit in turn to set triggers corresponding to those of the n lines of the respective said further set of lines which are energized, and then remove the energization of all the n lines of the respective first set of lines previously established and replace it by the energization of that one of the lines corresponding to the lowest-numbered (highest-priority) set trigger in the address circuit. Thus after all the address circuits have been thus enabled, the highestpriority input/output unit which requested service initially remains selected alone. The ring counter then supplies a signal to all the input/output units in common to cause service to commence at the selected input/output unit, then resets the triggers. The eight sets of n lines may be used for other purposes (than addressing) during the servicing.
