Title: Improvements in or relating to the measurement of short intervals of time
IPC: G01S7/22
Filed: 1945-09-13
Abstract: 604,463. Cathode-ray oscillographs. WHITFIELD, H. R. Sept. 13, 1945, No. 23686. [Class 37] [Also in Group XL (c)] A short time interval between two pulses is measured by using the first pulse to initiate an oscillation to produce a cathode-ray trace upon which the second pulse is produced as a peak, the first pulse also generating a further oscillation interlaced with the first oscillation and producing a trace intersecting the first trace, the point of intersection being adjustable so as to coincide with the peak, the adjusting means giving an indication of the time interval. The first pulse is applied at 2, Fig. 1, to render valve V2 non-conducting and valve V1 conducting to charge condenser C2. The charging potential of C2 is applied over condenser C1 to the grid of cathode follower valve V5 connected to the cathode-ray tube 5 to form the trace 11, Fig. 3, upon which the received pulses appear as peaks 12, 13 by application to terminal 20. A change-over of valves V1, V2, produced by their interconnection causes the discharge of condenser C2 and the termination of the saw-tooth wave, and the fly-back pulse is applied over condenser C3 to reverse multivibrator V3, V4 and make V3 conducting to alter the potential of the cathode of V1 and again reverse multivibrator V1, V2 to produce a second saw-tooth oscillation whose flyback re-sets multivibrator V3, V4 to make V3 non- conducting and maintain V1 non-conducting and V2 conducting until another pulse is applied at 2. Thus, each pulse applied at 2 produces two saw-tooth waves 22, 23, Fig. 2. These waves are applied over valve V7 to valve V9 whose suppressor grid is supplied with a pulse 7, Fig. 2, from multivibrator V3, V4. A potentiometer 6 determines the point on the slop of pulse 23 at which V9 conducts to produce a pulse 24, Fig. 2, which is combined with pulse 7 in valve V10 to produce pulse 25, Fig. 2, which is applied to the cathode-ray tube 5 to form a trace 15, 17, 16. The portion 17 can be moved along trace 11 by potentiometer 6 to coincide with a peak 12 or 13, the setting of the potentiometer indicating the time interval. Specification 582,170 is referred to.

Title: Improvements in coin inlet mechanism for use on prepayment meters for operation by coins of different values
IPC: G07F1/00
Filed: 1938-08-11
Abstract: 501,256. Prepayment mechanism for meters. LANDIS & GYR AKT.-GES. Aug. 11, 1938, No. 23719. Convention date, Sept. 10, 1937. Addition to 480,552. [Class 27] In the construction shown in Fig. 1 of the parent Specification, a circular guide bar 135 is provided on the cover plate of the drum closing to co-operate with the feeler 41 of the slide 29 bearing the operating members 33, 34, 35. If, due to the coin being worn at the periphery and not being circular, the projection 31 on the slide 29 has not entered a notch 23 in the coin-operated slide 20, the feeler 41, when it has left the high portion of the cam 16, will be in the position d on the outside of the bar 135. The bar will thus prevent the members 33, 34, 35 from being jolted into engagement with the wheel 36 of the quantity mechanism after the drum has beem partly rotated, and so prevent an incorrect quantity of commodity from being delivered for such a coin-

IPC: G09F11/02
Filed: 1969-05-13
Abstract: 1,248,488. Signal display device. SALFORD ELECTRICAL INSTRUMENTS Ltd. 12 March, 1970 [13 May, 1969], No. 24355/69. Headings G4H, G4Q and G5C. A signal display device mounted in a vehicle for warning drivers of adverse road conditions comprises a clockwork motor (not shown) which drives a warning drum 1 and four escapement mechanisms such as 3, 5 having rods 3, 6, 7, 8 and operated by radiated signals. The motor also drives, via a differential gearing a brightly striped drum 9 and a bell-striker 11 to draw attention to the drum 1. In the inoperative position, the rod 3 engages the pin 4 and the drum is prevented from turning. The rods 6, 7, 8 are normally in a position remote from the drum but can be actuated to obstruct the path of pin 4. In operation to display the legend " Repairs ", " Snow " or " Fog ", the appropriate rod 6, 7 or 8 is actuated and then rod 3 is actuated allowing drum 1 to rotate and the required legend to be seen through a window in the housing (not shown) of the device. To display " Accident " only rod 3 is actuated allowing the drum 1 to rotate through 180 degrees and be arrested by the returned rod 3 engaging pin 13. Actuation is performed by the output of a radio receiver which is located in the vehicle and which is tuned to four frequencies of amplitude-modulated radio waves radiated by inductive loops placed in or on the road. The first loop operates at one of three frequencies to select a rod 6, 7 or 8 while the second operates rod 3 to set the drum into motion. In emergency only one loop is used; this merely operates rod 3. The device is suitable for use in conjunction with the road toll charging system described in U.K. Specification 1,176,467.

Title: Apparatus for controlling winding operations in a spinning machine
IPC: D01H1/36
Filed: 1964-06-11
Abstract: 1,010,048. Winding and traversing mechanism for spinning machines. ZINSER TEXTILMASCHINEN G.m.b.H. June 11, 1964 [June 24,1963], No. 24357/64. Heading D1D. A yarn winder for a spinning machine includes two first electromagnetic couplings 50, 52 that are alternately energized to cause opposite traversing motions, a cam 80 that is rotatable to cause switch 104 to effect said alternate energization of the electromagnetic couplings 50, 52, a second electromagnetic coupling 76 that connects cam 80 to a drive shaft 78, and means for energizing and de-energizing the second coupling 76 at the end of each traverse stroke. As illustrated, the reciprocating means travels between limit switches 96, 98 that are normally biased to their open position. When the reciprocating means strikes and closes switch 98 the electromagnetic coupling 76 is energized via a change over switch 102 to couple the cam 80 to the drive shaft 78. When the high part of the cam reaches the cam follower, change over switches 102, 104 are operated, the change over of the switch 102 de-energizing the coupling 76 to stop the cam 80 and the change over of the switch 104 de-energizing coupling 50 and energizing coupling 52 to reverse the direction of the reciprocating means. The reciprocating means then moves towards the limit switch 96 and, on striking and closing it, energizes the coupling 76 via the switch 102 in its new setting to once again couple the cam 80 to the driving shaft 78. When the lower part of the cam 80 reaches the cam follower the change over switches 102, 104 are returned to the setting shown to stop the motion of the cam, de-energize the coupling 52, energize the coupling 50, and so reverse the direction of the reciprocating means. In the particular embodiment, Fig. 1 (not shown) a carriage 70 reciprocates the package 48 relatively to a flyer 26. Rotation of the cam 80, on energization of the electromagnetic coupling 76, rotates gearing 86, 92 causing the spacing between the limit switches 96, 98 to be adjusted and so adjust the length of traverse. The input drive to the electromagnetic clutches 50, 52 is via a shaft 40 driven via cone pulleys 18, 38 coupled by a belt 36, the belt 36 being displaced along the cone pulleys 18, 38 each time the cam shaft 78 is rotated. In this manner the rate of rotation of the electromagnetic clutches 50, 52 is varied. The flyer 26 is rotated at a constant speed by a drive 30, 32, 34a, 34, 28; and the reciprocating package 48 is driven via the cone pulleys 18, 38, shaft 40, gears 42, differential 44, shaft 45, universal joint, shaft 47 and worm gear 47a meshing with a worm gear by which the package 48 is driven.
