Patent GB-1161930-A (GB)
Title: Indicating Circuit
Inventor: TAYLOR ROBERT WILLIAM
IPC: G06F12/123
Filed: 1967-07-11
Abstract: 1,161,930. Data storage. INTERNATIONAL BUSINESS MACHINES CORP. 11 July, 1967, No. 31745/67. Heading G4C. The least recently accessed of a plurality of storage registers is indicated by a multi-input " indicator " respective to the register, accessing of a given register deactivating all inputs to the corresponding " indicator " and activating inputs of the " indicators" associated with other registers, simultaneous activation of all the inputs of a given indicator causing it to emit a " least recently accessed " signal for the respective register. In one embodiment, a 4 x 4 matrix of bietable latches lacking the leading diagonal is provided in the case of 4 registers. Access to the nth register resets all the latches in the nth row and sets all the latches in the nth column, so that the set state of the jth row, kth column latch indicates that the kth register has been accessed since the last access to the jth register. The set outputs of all the latches in a given row (say the nth) go to an AND gate which thus produces an output when the nth register is the least recently assessed. A second embodiment uses only half the matrix of latches by using the reset outputs of those retained as AND gate inputs in place of the set outputs of the corresponding latches deleted. In an application, an input address tag is associatively compared with tags stored one in each first register of four pairs of registers, a match causing the contents of the second register of the pair giving the match to be accessed and used to address a memory which may be of lower speed than the registers. The accessing operates the system of either of the two preceding paragraphs, which selects the least recently accessed register-pair to be loaded from the memory with a tag and address in the event that an input tag does not match any of the tags stored in the first registers of the register-pairs. A " register may store any number of words. Reference has been directed by the Comptroller to Specification 979,633.

Abstract: 1,169,553. Hydraulic brakes. GIRLING Ltd. 14 June, 1967 [14 July, 1966], No. 31768/66. Headings F2E and F2F. Each front brake shoe of a vehicle hydraulic braking system is operable through a main and an auxiliary hydraulic pressure line coupled respectively to main and auxiliary piston faces in separate working spaces within one slave cylinder, so that in the event of failure of the main hydraulic line some braking effort is still available. As shown in Fig. 1, a tandem master cylinder 1 is operable by an air actuator 6 which receives air under pressure from a reservoir 8 when a foot control valve 10 is actuated. Each front brake slave cylinder 18 has a stepped bore and a separate piston 24, 26 respectively in each bore. The working space behind piston 26 is fed by a main line 20 and that behind piston 24 by a line 12A. Under normal operation the effective braking pressure is developed across the full area of piston 26 while piston 24 is subjected to equal pressures at both ends so it does no work. Should main line 20 fail, pressure will still be applied to the working face of piston 24 which will operate to actuate the front brake, although with a reduced braking effect. The small piston area is preferably 50% that of the large one so that the driver will sense that there has been a failure. Alternatively the pistons may have equal areas and an electrical warning device (e.g. pressure switch) provided to indicate failure of line 20. The rear brake slave cylinders 16 are connected to a branch line 12B through a load conscious reducer valve 14. In a modified slave cylinder arrangement, Fig. 3 (not shown) the large piston is in the form of a ring through which the small piston extends in slidable sealed relation. In normal braking, effort is derived from both pistons and if either line 20 or line 12 fails there will be reduced braking effort. In a further modification. Fig. 2 (not shown), the pistons 24, 26 are formed from one piece of material.

Energization of a coil C attracts an armature A<SP>1</SP> on the upper end of a vertical shaft A towards a magnet core C<SP>2</SP> against the action of a return spring A<SP>5</SP> connected at one end to an arm A<SP>4</SP> on the shaft, whereby a number of pinlike bridging contacts D carried by spring arms A<SP>3</SP> on the shaft make or break contact with respective pairs of fixed contact pins D<SP>1</SP>, D<SP>2</SP>. The shaft A is held in its operated position on de-energization of the coil C by a projection G4 on a latch G, pivoted at G<SP>1</SP>, which moves from its normal position, Fig. 8, to its latching position, Fig. 9, under the action of a spring G3 upon movement of the arm A<SP>4</SP> to its operated position. Movement of the latch G to its latching position releases a plunger F<SP>1</SP> which drops a limited distance and locks the latch, thus preventing undesired tripping of the switch due to shock. As shown, this dropping of the plunger also de-energizes the coil C by striking a lever E<SP>3</SP> pivoted at E4 and biased by a spring E<SP>5</SP>, the lever carrying a bridging contact E co-operating with fixed contacts E<SP>1</SP> connected in the coil circuit. The switch may be electrically tripped, in which instance the plunger Fl and latch G are magnetic and the plunger is surrounded by a tripping coil F having a yoke F<SP>2</SP>, F3, energization of the coil F causing the plunger to be raised, whereupon the latch is attracted to the yoke and the arm A<SP>4</SP> is returned by the spring A<SP>6</SP>. In another construction, the yoke F<SP>2</SP>, F<SP>3</SP> is omitted and the upper end of the plunger engages the latch to trip the switch. Further, the coil F may also be omitted (Figs. 5-7, 10, 11, not shown) and the plunger raised manually by means of a handle to trip the switch.

Abstract: 1,221,769. Implement draw gear. MASCHINENFABRIK FAHR A.G. 26 June, 1969 [19 Aug., 1968], No. 32401/69. Heading A1P. The draw bar 1, pivotally connected to a combine harvester at pivot 3 and to a tractor hitch bar, is movable between two positions, a transport position (Fig. 1, solid lines) and an operating position (broken lines), in each of which position the draw bar is held by a spring-loaded catch and the catches being interconnected such that movement of one to an operating position is accompanied by movement of the other to an inoperative position. The draw bar is slidable on rail 23 beneath a plate 25 which forms part of the frame 2 of the combine harvester, its lateral movement being limited by abutments 4 and 5, the positions of which are adjustable in the direction of travel by means of screws 20 which engage slots in the frame 2. A two armed lever 6 is pivotable about a horizontal pin 7 and can rotate to positions in which one or other of the arms 6<SP>1</SP> extends into the path of the draw bar. In lever 6 a centrally mounted lug 9 has attached through the hole 10 the lower cranked end of a rod 11. A lever 12 pivotable about a pin 13 aligned with pin 7 guides rod 11 which engages a hole 14 in the cranked end of the lever. Pivoting movement of the lever 12 is limited by abutments 15 and 16 provided on the frame 2. A compression spring 17 located on rod 11 presses against an abutment on the rod and against the lever 12, the consequent pressure on lug 9 causing one or other of the arms 6<SP>1</SP> of lever 6 to pivot downwards to a position where it acts as a draw bar stop depending upon whether lever 12 is set against abutment 15 or 16. The draw bar can thus be locked in one of two positions. The lever 12 is positioned such that a pull on it by an attached rope or chain extending through an eye 19 on the draw bar to the tractor causes the lever 6 to move from one position to the other, thereby releasing the draw bar which can then be swung by suitable steering of the tractor into the alternate position. Free play of the draw bar in its locked positions is limited by adjustment of the abutments 4 and 5, and of the heights of rail 23 by means of eccentric screws 24.

Abstract: 1299855 Tobacco smoke filters MOLINS MACHINE CO Ltd 3 Dec 1969 [4 Dec 1968 27 June 1969] 57703/68 and 32625/69 Heading A2C A filter for cigarettes &c comprises a number of separate layers of granular, powdered or like material held between coaxial tubes of porous material, the arrangement being such that smoke passes radially through the tubes and granular material. In one embodiment, a filter plug 2, Fig. 1, attached to a cigarette 1 consists of porous paper which is folded, wound or otherwise arranged into a number of substantially concentric layers 3 separating the layers of granular material and is terminated at its ends by sealing elements 5, 6. The mouthpiece end of the plug is fitted with a conventional stub 7 e.g. of paper or cellulose acetate fibres. The element 5 is apertured at 11 to communicate with an axial channel 9 and the element 6 has channels 12 communicating with an annular channel 10 so that smoke is constrained to pass radially, as shown by the arrows, through the porous walls 3 and layers of granules. The channels 9, 10 may contain spacing elements, such as axially extending ribs, or porous material, and the porous paper 3 may be corrugated, knurled, or otherwise roughened to assist in holding the granules against displacement. The elements 5, 6 may be interchanged so that smoke flow is radially inwardly, and two filler plugs, sharing a common element 6 or 5, may be arranged end to end. A construction suitable for production as a continuous rod is shown in part-section in Fig. 4 in which concentric tubes 103 of porous paper, spaced apart by sets of concentric rings 105 of thick paper, are enclosed by a paper tube 102 and outer wrapper 101. Alternate sets of rings 105 have a band of paper 106 between the outermost tube 103 and the tube 102, and the other alternate sets have a central, non- porous stub 108 and are spaced from the tube 102 by dimples 107 in the latter. The rod is severed at the regions A-A. The Specification describes a machine for making such continuous rod, using a single web of porous paper on to which strips to form the rings 105, and the stubs 108, are secured at intervals by adhesive. Then, after application of the granular material to the web the latter is slit longitudinally into strips of graduated widths which are stacked one above the other and formed into the concentric tubes. A web of paper to which the spacers 106 are applied and in which the dimples 107 are formed is subsequently applied to form the tube 102, followed by the application of the outer wrapper 101.

Filed: 1968-01-08
Abstract: 1,211,131. Coiling wire. INDUCTIVE APPLIANCES (1963) Ltd. 17 Dec., 1968 [8 Jan., 1968; 9 July, 1968], Nos. 1089/68 and 32651/68. Heading B3E. [Also in Division H1] A method of making electrical inductors comprises drawing steel strips or wires from spools by driving rollers 5 and 6 and bringing them into contact with one another to form a core 7. A first paper lapping 8 is applied to the core 7 by rotating a reel 9 of paper tape around the axis. One of two coils of insulated copper wire are then wound over the paper lapping in the opposite sense by means of a winding head 11. At the winding head 11 the end of the wire carried by a spool 68- is led outwardly, with a component of motion parallel with the axis, over pulley 57, inwardly with a further component parallel with the axis, over pulley 58 and then around pulley 59 to pulley 60 forming a loop. The end of the wire is then attached to the core. A disc 56 and the spool 68 are rotated in an anti-clockwise direction by a drive pulley 55; the drive to the spool 68 being so arranged that the spool is driven at a speed equal to or slightly in excess of the speed necessary to supply wire to the pulleys 57-60 when the spool is full. As wire is drawn off the spool, the latter has to rotate faster and this is permitted by a free wheel device 85 which then over-runs. The pulley 60 rotates the loop around the core in an anti-clockwise direction as the core ismoved axially thus winding on the wire. The second coil is wound over the coil 10 in the opposite sense by means of a winding head 13 which is identical to the winding head 11. After receiving the two coils of wire the core 12 has a second paper lapping applied to it at 15 after which it is cut into required lengths by a travelling circular saw 20.

Abstract: 347,576. Variable-speed gearing. DEMOCRATIS, A. J., 38, St. Augustine's Road, Camden Square, London. Oct. 28, 1929, Nos. 32746/29 and 17915/30. [Class 80 (ii).] A gear device automatically variable e with load comprises planetary masses carried by a driven shaft, the alternating rearward impulses of the masses being converted into forward impulses by the reaction of a detent. The detent may be reversible to reverse the driven shaft. Mass W, Fig. 1, revolves in direction of arrow B about axle C which planetates about centre 0. A crank CK is offset from the mass Wand is connected by a link KN to a lever NO pivoted at 0 and carrying a pawl P engaging a fixed detent R. As mass W moves from position I to position IV, there is a resultant centrifugal force giving bodily impulse to axle C in the forward direction indicated by arrow A. Lever end N has come to point N<1>, and cannot move back. Therefore as mass W moves beyond position IV, axle C must move further in the direction of arrow A. A realization is shown in Figs. 9, 10, 11 and 12. Secured to driven shaft 28 is the carrier 25 of the axles 37 of the eccentric masses 40, which are driven through gearing 35, 36 from driving-shaft 22. Balanced cranks 49 corresponding to the crank CK of Fig. 1 are connected by links 50 to a lever 51, Fig. 11, which is secured to a sleeve 29 surrounding shaft 28 and carries an eccentric 53, Fig. 9, which takes the detent action. This detent, which is shown in Fig. 12, is reversible. It comprises parts 56, 60, 62, 64, 69, 70, and is operative to cause shaft 28 to be driven in one direction or the other according as cam 80 or cam 81, Fig. 9, is engaged by lever 74, Fig. 12. The complete gear is thus controlled by sliding a sleeve 79, Fig. 9, operated by a control lever 85. Solid high-speed driving is brought in automatically by centrifugal weights 47, Fig. 10, which tighten clutch bands 43 upon drums 41 associated with the masses 40. Other forms of detent are described which yield so as to generate further forward impulsive forces transmitted to the driven shaft. These yielding detents are fully described in the Specification referred to.
