Abstract: 1,107,974. Grinding. B. E. DOWNS, and K. G. NEWEY. 22 Dec., 1966 [23 Dec., 1965], No. 54761/65. Heading B3D. A feed control device 25, Fig. 1, for infeed control of a centreless grinding machine having a rotatable grinding wheel 11, a control wheel mounted on a slide 14 to rotate on an axis parallel with or inclined at a small angle to that of the grinding wheel, the control wheel and grinding wheel being aligned in substantially co-planar relationship and the control wheel being movable with the slide towards and away from the grinding wheel, the control device comprising fluid pressure operated control means adapted for mounting on a centreless grinding machine and operable to control the feeding of the control wheel towards and away from the grinding wheel. The slide 14 carries the control wheel and a work rest 21 and is movable along a guideway 15 on the machine bed 10 by rotation of a hand wheel 19 connected to a lead-screw 17 which is rotatable in a bracket 18 on the bed and engages a nut 20 on the slide. Rotation of the screw is used to initially adjust the slide and thereafter the screw is looked in position by a lever 24, the infeed of the control wheel then being effected by rotation of the nut which is secured by a clamp 33, Fig. 3, to a lever 32 of the control device. The lever is formed with a slot 31 engaged by a roller 30 on a block 29 slidable in a guide structure 28, the block being connected to the rod 41 of a pneumatic cylinder and, through a lost-motion connection 47, 48 to the rod 45 of an hydraulic damper 44. During automatic operation, the supply to cylinder 40 is controlled by valves V1, V2 actuated by pins 49, 50 secured to the block. A third valve V3 is actuated when an edge 56 of the block engages a trigger 53 to operate the cylinder of a device associated with the work rest 21 for ejecting a finished workpiece. A pneumatic circuit is described which permits single or continuous grinding cycles to be effected. During infeed, the control wheel is advanced rapidly until the damper is operated to oontrol the rate of grinding. At the end of the infeed, grinding continues under the control of a regulator for a predetermined time before the wheel is retracted. In an alternative embodiment, the nut 20 has a pinion engaged by a rack on the piston-rod 41.

Title: Parallel self shifting information in a plasma display/memory panel
IPC: G09G3/28
Filed: 1974-12-30
Abstract: 1489619 Matrix displays UNIVERSITY OF ILLINOIS FOUNDATION 30 Dec 1974 [30 May 1974] 56071/74 Heading G5C A method of shifting data across a gas discharge display/memory panel having rows of display and transfer cells connected to sources V Y , V SH1 , V SH2 , includes applying erase signals to each row of cells when the data has been shifted to the next row. Signals V X , V Y , V SH1 , V SH2  are applied to the electrodes so that initially V X -V Y  is a sustain signal and V X - V SH1 , V X -V SH2  are erase signals. At the beginning of a shift cycle, data is shifted to the first rows of transfer cells by a phase change in V SH1  which alters V X -V SH1  to a sustain signal on the first rows. The phase of voltage V Y  is changed to alter V X -V Y  to an erase signal. Data is moved successively to the second row of transfer cells and to the display cells by applying a sustain signal to the respective row and an erase signal to the row from which the signal has been transferred. Alternate rows in the X array are grounded to prevent undesired data shifting. In another embodiment data can be shifted in both X and Y directions.

Patent GB-580012-A (GB)
Abstract: 580,012. Lighting burners. BRITISH THOMSON-HOUSTON CO., Ltd. (General Electric Co.). Feb. 25, 1944, No. 3574. [Class 75 (iii)] [Also in Group XXVII] A low-tension ignition system for igniting burners or for other purposes comprises a rotating magnet type magneto 10 associated with a circuit-breaker 16 and has a condenser 17 in parallel with an output circuit which includes a series saturable reactor 18, an alternating highoutput current being applied to the output circuit responsive to the periodic discharge of the condenser through the reactor on substantial magnetic saturation of the reactor. The reactor is connected to the arm 19 of a distributor, the contact terminals 20 of which are connected to the primaries of transformers, whose secondary windings 23 are connected across the terminals of spark plugs 25. Thus when the magneto voltage is applied across the condenser 17 and the output circuit in parallel therewith the reactor offers high impedance in its unsaturated condition and a relatively high charge passes into the condenser. The reactor becomes substantially saturated and its impedance is reduced so that the condenser discharges through the reactor and through one of the primaries 21 thereby inducing the sparking voltage across the corresponding spark gap.

Title: Method of and apparatus for indicating the lower and higher
IPC: B60T8/172
Filed: 1971-12-15
Abstract: 1364637 Aritiskid braking systems AISIN SEIKI KK 15 Dec 1971 [15 Dec 1971 (2)] 58291/71 Heading F2F [Also in Divisions G4 and H3] Electric signals representing the speed of two rotary members are examined and a signal representing the lower speed is directed to an output lead 45 (Fig. 1) from a bi-stable 39. In the embodiment of Fig. 1, two sensors 11, 12, which may for example be magnetic or photo-electric, feed signals, the frequency of which represent the speed of the two rotary members, via amplifiers 13, 14, NAND gates 17, 19; 18, 20 and differentiators 23, 24, 25; 26, 27, 28 to monostables, the outputs 204, 205 from which are directed to the bi-stable 39 which is triggered by the trailing edge of the output pulse from the monostable associated with sensor 11 and reset by the trailing edge of the pulse from the other monostable. This results in signals on lead 45 at the frequency of the slower moving of the rotary members. The monostable outputs are also fed to a NAND gate 37, the output from which after inversion by NAND gate 42 is fed together with the bistable output to a NAND gate 43. The output of this gate is fed together with the output of the monostable associated with the sensor 11 to a further NAND gate 38 to derive signals on lead 44 at the frequency of the faster moving of the rotary members. In a modification of this embodiment (Fig. 11, not shown) the outputs of the two monostables are each connected to one gate (40, 41) in the bi-stable, the output of the second gate (41) providing a signal at the frequency of the slower rotary member. In an application of the invention to an antiskid device the higher frequency pulses are counted in a first counter 101, 102, 105, 107 of capacity 15 and the lower frequency pulses are counted in a second counter 109, 110, 111, 112 of capacity 15, the arrangement being such that the second counter is reset at a count of 1 in the first counter. The state of the second counter is examined when the first counter cycles through zero and if the second counter has counted more than 12 pulses whilst the first counter has ranged from a count of 2 to its full count the output of a NAND gate 114 is at "0" so that the sampling signal from the first counter to bi-stable 108 results in a "0" signal at its Q output. If however the second counter has counted less than 12 pulses the "1" output from NAND gate 144 sets bi-stable 108 to its "1" state to render conductive transistors 116, 120 and so energize solenoid 122 which controls a valve reducing the hydraulic brake pressure. If the bi-stable is not reset within a predetermined time interval, monostable comprising gates 122, 125, 117, capacitor 124 and resistor 126 resets the bi-stable automatically.

Abstract: 1366939 Knitting-machines BROTHER KOGYO KK 29 Dec 1971 [29 Dec 1970] 60299/71 Heading D1C A hand knitting-machine has a patterning mechanism camprising a pattern, i.e. a punched card which can be scanned line-by-line by readers carried in a support movable across the pattern. The punched card 5, Figs. 2, 3, is located by pins 101 on the perforated upper surface 6 of a support 4 in the needle bed 1. A perforated cover 102 is placed over it. The pattern is read by reading members 54 movable along elongated plates 55 by a frame 13. The members 54 control a bank of needle selecting members 9 which can be pushed against the needles 2. The frame can be looked at each line of the pattern by an inclined projection 27, Fig. 4, of a spring urged member 18 engaging openings 8 in the support. A second member 17 carries a projection 25 engaging the teeth 24 of a movable feed plate 23. The plate 23 is urged by a spring 34 against a cam 37 turned at each reciprocation of the carriage by contact with lever 35. The frame is thus reset at the next opening 8. The plates 55, which support the members 54, have slots cut in them and through which the lower arms 69 of cranks 67 pass. At the operators instigation, the plates are raised to present the members 54 to the card. Those plates associated with members 54 reading perforations in the cards are able to move longitudinally, so pivoting the cranks. They in turn pivot cranks 80, see Figs. 9, 10, engaged in slots 83 in the selecting members 9. The members are raised by the pins 78-cam slots 79. Projections 76 are provided at spaced intervals along the member 9. Thus, depending on the location of the perforations in the pattern card, selected members are raised to select certain needles from groups across the bed. The holder 72 carrying the members is moved towards the needles advancing selected ones of them, by a manually operated linkage. The frame 13 is advanced at each reciprocation of the carriage, but is released when it contacts a manually set stop 48, usually placed at the end of the pattern. The frame returns to its starting position under the action of a spring 16.
