Title: Water-cooled cylinder for internal combustion engines
IPC: F02F1/16
Filed: 1968-04-17
Abstract: 1,219,532. Cooling I.C. engine cylinders. MASCHINENFABRIK AUGSBURG-NURNBERG A.G. March 20, 1969 [April 17, 1968], No. 14813/69. Heading F1B.

Title: Improvements in or relating to means for applying metal foil to paper or other insulating material in strip form
IPC: B32B37/22
Filed: 1945-06-12
Abstract: 593,174. Compound sheet materials. SPORING, P. A., JOHNSON, C. P., and TELEGRAPH CONDENSER CO., Ltd. June 12, 1945, No. 14836. [Class 140] To a continuously - fed, adhesively-coated paper strip 5 are applied successive lengths of metal foil, wound from a roll 19, the rotation of the roll being arrested when a predetermined length of metal foil has been wound off, whereby the foil is severed, such stoppage being maintained over a sufficient period of time to produce the required gap between successive lengths of foil. The periodic stoppage of the roll with the consequent severing of the foil is effected by gripping roll 19, between two plates 21 controlled by periodically exciting a solenoid which is activated when the forward edge of the foil attached to the paper comes under metal roll 30, thereby completing an electrical circuit. The length of foil is determined by adjusting the distance of roller 30, from roller 19. After the circuit is broken by the severing of the foil, the current through the solenoid is maintained for a variable period of time by the discharge of a variable number of capacitators connected in parallel with the solenoid and thus the length of the gap between successive lengths of foil is determined. Further alteration in the length of the gap can be achieved by altering the rate of travel of the paper strip 5. The composite strip is wound on to a powerdriven roller 8, driven at a greater peripheral speed than that at which the paper strip is applied to the metal foil by the roller 7 and controlled by a slipping clutch, whereby the paper is maintained taut. The apparatus can be adjusted to accommodate various widths of paper strip and metal foil.

Title: Improvements in or relating to circuit arrangements for separating electric signal pulses
IPC: H04N5/21
Filed: 1938-05-19
Abstract: 515,210. Television; code telegraphy. WHITE E. L. C. May 19, 1938, No. 14917. Addition to 491,728. [Classes 40 (iii) and 40 (v)] Pulses of differing duration, including short pulses due to spark interference, are applied to three or more transmission channels, (e.g. a single delay network with tappings) connected to a single signal-responsive device, the delays in the several channels differing by amounts such that the device is operated only when at least three channels deliver output signals simultaneously. In a television system, long (e.g. frame) and short (e.g. line or interference) pulses are applied to a delay network 3, Fig. 1, from which tappings 6 ... 10 are taken to an amplitude filter 4, in order to isolate the long pulses. The resistance 10 is such as to give a greater amplitude output than resistances 6 ... 9. The delay in the network is of the same order as the duration of the long pulse. The preferred amplitude filter comprises two valves, Fig. 4, connected as a regenerative amplifier as des-. cribed in Specification 373,309; the combination passes current at the level 19, Fig. 5, and ceases to pass current at the level 20, so that, e.g., a long pulse of 4 micro-seconds is passed without any shortening, although it is delayed by 1 micro-second. Specification 455,375 also is referred to.

Title: Improvements in and relating to the automatic steering of vehicles
IPC: B62D1/26
Filed: 1956-05-14
Abstract: 832,742. Steering vehicles. COMPAGNIE GENERALE DES ETABLISSEMENTS MICHELIN. May 14, 1956 [May 12. 1955; Jan. 28, 1956; April 26, 1956], No. 14923/56. Class 79(5) In a road vehicle having a feeler adapted to be brought into a position to follow a reference track and connected to the steerable wheels to guide the vehicle, means are provided which during automatic guiding of the vehicle indicate.when the vehicle is off-course, the means comprising a member movable with the reference track and supported by a member fixed to the vehicle, the members closing an electric circuit when the vehicle is off-course. As shown, the road vehicle can be automatically steered by rollers 10 engaging a gutter 1a in the road surface, the rollers being carried by a frame 2 universally jointed at 19, 20 to a longitudinal lever 3 universally jointed at 27, 29 to a transverse frame member 26, and the pin 27 pivotally carrying a bell crank lever 4 connected by a rod 5 to the steering wheel mechanism (not shown) and having an arm 31 adapted to engage a slot 32 in the lever 3. The rollers 10 can be lifted clear of the gutter 1a by means of a driveroperated rod 33, such lifting disconnecting the slot 32 from the arm 31. Mounted in bearings 25 on the vehicle frame are trunnions 37 of a square section or ribbed circular shaft 11. Slidable axiallv on the shaft 11 is a member 3a carrying a part 17a adapted to engage the gutter 1a. In operation, if the vehicle deviates sufficiently from the path set by the gutter 1a, the member 3a is slid on the shaft to such an extent that one of members 12 of the member 3a contacts fixed stops 13 on the shaft 11, whereby the electric circuit is completed either to operate a warning device (not shown) or apply the vehicle brakes. When the rod 33 is pulled to transfer the steering from automatic to manual, the part 17a is lifted clear of the gutter by rotation of the shaft 11 by a spring 43 which is connected to a member 40 keyed to the shaft 11. The lower end 41 of the member 40 is so shaped that in its automatic steering position it bears against the end 42 of the lever 3. Movement of the lever 3 by action on the rod 33 to pass from automatic to manual steering causes the end 42 to pass down to the end 41 whereby the spring 43 turning the shaft 11 causes the end 41 to ride over the top of the lever 3 to hold the rollers 10 disengaged from the gutter 1a. Movement of a lever 45 on the member 40 by the driver causes the rollers 10 and member 3a to resume their automatic steering positions shown. Rotation of the shaft 11 in a clockwise direction is limited by an arm 38 thereon engaging a stop 39 fixed to the vehicle frame. In modifications (a) the part 17a, Figs. 6 and 8 (not shown), is formed to engage a rail upstanding from the road surface and (b) the member 3a, Figs. 7 and 8 (not shown), is pivoted intermediate its ends to the shaft 11 about a longitudinal axis of the vehicle, the upper end of the member 3a being adapted to contact two fixed stops to complete the electric circuit.

Abstract: 741,333. Sound reproducing circuits. FERRANTI, Ltd. May 27, 1954 [May 29, 1953], No. 14944/53. Class 40 (4). A circuit for eliminating noise having a pulsed waveform from the output of a gramophone pick-up 10, comprises a gate 15 adapted to be closed by the output from a pulse generator 19 triggered by the rectified output of a filter 17 which passes only the ultra-audio frequencies which would be present in a noise of this type. The main signal path may include a delay line 14 so that the noise pulse may occur at the midpoint of the blocking pulse. The trailing edge of the blocking pulse from the generator 20 may trigger a further pulse generator 20 whose output prevents the further operation of the generator 19 for a prescribed period thereby preventing too-frequent blocking of the signal. A bypath 34 to the delay line 14 may be provided, the gate 15 being arranged to feed the undelayed signal to the reproducer 13 during the interval when the delayed signal is blocked, thereby maintaining continuity of signal. The gating circuit may comprise two gates operated in push-pull to avoid unwanted noise due to the application of the gating voltages.

Abstract: 1,107,191. Rotary presses; cylinder tripping. J. V. BAILEY, G. C. FORTIN, and W. S. FORSTER. 7 April, 1965 [10 April, 1964], No. 14972/64. Heading B6C. In a multi-colour rotary offset press for simultaneous printing on both sides of a web W each printing " couple " comprises an offset cylinder 1 (or 2) and two co-operating plate cylinders 3 and 5 (or 4 and 6). The cylinders 2, 4 and 6 are moved relative to the web as a unit by a pneumatic cylinder and lever assembly 16, 18 which acts through rods 21, 22, 23 upon eccentric bearings in which the cylinders are mounted. In the other " couple " only the plate cylinders 3 and 5 are moved as a unitby an assembly 15, 17 acting through rods 25 and 26-as the offset cylinder 1 is fixed. In order to allow adjustments in the positions of the movable cylinders of the press each of the rods 21, 22, 23, 25 and 26 is connected to the associated pneumatic and lever assembly through a two-part interengaging screw adjusting device. As shown in Fig. 3 three such devices, 52, 52A, 53, 53A and 54, 54A, are placed side-by-side in the tripping apparatus associated with the cylinder unit 2, 4, 6, manual rotation by a spanner of the device 52, 52A associated with the offset cylinder 2 effecting, via gearing 30, automatic rotation through predetermined degrees of the devices 53, 53A and 54, 54A which are connected to the eccentric bearings of respective plate cylinders 4 and 6. The threads 52, 53 and 54 of the devices are alike but of different pitches so that a given angular movement of the square on device 52, 52A, although it causes the other devices to turn through the same angle, will advance or retract them longitudinally by different amounts so that the desired setting of the different cylinders may be achieved. The devices 53, 53A and 54, 54A may be adjusted independently of the device 52, 52A so that the positions of the cylinders 4 and 6 may be altered relative to that of the cylinder 2. The cylinder units 2, 4, 6 and 5, 3 are locked in operative position through the actuation of pneumatic cylinder devices which move lever stops 32 into positions whereby the levers 18 and 17 are held against abutments 36 located in the upper part of the press. In the printing " couple " 1, 3, 5 the adjusting devices are similar to the devices 53, 53A and 54, 54A. Worm and worm-wheel means are described with reference to Fig. 4 (not shown) by which a fine adjustment for the peripheral setting of each plate cylinder may be accomplished. Means (not shown) are also provided for moving the plate cylinders axially for registration purposes. Each colour cylinder 5 and 6 is sectionally inked in different colours supplied from its associated divided fountain 10.

Abstract: 733,680. Sliding clasp fasteners. MANES, G. MASTRACCHI-. May 29, 1953 [May 29, 1952]. No. 14988/53. Class 44. A sliding clasp fastener comprises two sectional strips 1, 2, Fig. 1, of resilient material, the strips 1 having a continuous leaded section and the strips 2 or continuous pincer-like section having arms to embrace the leaded section both strips having undercut engaging surfaces 4 to permit of mutual gripping engagement when the fastener is closed, wherein the gripping portion 10 of each pincer arm is provided with an incision 3 extending longitudinally of the strip 2. When a tensile load is applied to the fastener, pressure between the faces 4 acts in the direction shown by the arrow 7. A component 9 of the force causes the portion 10 to pivot about an imaginary point 6 which is determined by the incision 3. The web 11 of the section 1 is therefore clamped between the pivotting portions 10. Instead of the incisions 3 extending in the directions shown in Fig. 1 they may extend in directions towards the largest cross-sections of the portions 10 and may be perpendicular to the surfaces 4. In the embodiment of Fig. 4 the outer end faces of the portions 10 engage undercut lateral shoulders 12 on the web 11.
