Title: Improvements in or relating to pneumatic tyres
IPC: B60C9/20
Filed: 1957-03-18
Abstract: 855,729. Pneumatic tyres. PNEUMATIQUES & CAOUTCHOUC MANUFACTURE KLEBER-COLOMBES. March 18, 1957 [March 17, 1956], No. 8824/57. Class 144 (2). A pneumatic tyre comprises a carcase of an even number of symmetrically cross-laid plies 6, 7 of bias-cut parallel cord fabric, and a crown reinforcement of an even number of cross-laid parallel cord plies 3, 4 having the same cord angles as the carcase plies, the crown ply cords being substantially inextensible and being substantially in side by side contact within their plies. Such a tyre is made by building into the flat-band tyre blank crown plies having spaced cords 9, Fig. 6, calendered between rubber coatings 10, 11 which strike through between the cords, the plies having an initial cord angle (with respect to the circumferential direction) greater than that desired in the finished tyre. On shaping of the fland band, the cords in the crown plies are crowded together, Fig. 7, and possibly imbricated, whilst retaining a rubber film therebetween, and the cord angle is decreased. The crown ply cords may be of metal, glass, or natural or synthetic textile material.

Convention date, March 29, 1930. [Class 106 (i).] A counter for measuring the duration of telephone calls is zeroized, started, and stopped by manipulation of a knob 5 depression of which rocks a spring-controlled yoke 31 carrying rollers 34 for zeroizing the counting drums 18, 19 by engaging heart cams 37 thereon. The ascent of the yoke also effects (a) the disengagement of the actuating pawls 20, 21 and (b) the release by lugs 44 of an inner yoke 39 carrying the spring detents 40, 41 and a spring contact 42. The counter is actuated at every ten seconds by electric impulses from a master clock, these impulses passing by way of contact springs 9, 10, Fig. 7, (closed by rotation of the knob 5) to a magnet 14 the armature 16 of which carries the actuating pawls. Overthrow of the pawls is prevented by a stop yoke 58 and transfer is of the deep notch type the higher pawl being normally held out of driving engagement by a recessed disc carried by the lower wheel. Signals and alarms. A lamp lights for ten seconds before and after each three-minute period. For this purpose the drum 19 is provided with a contact 43, to engage the spring contact 42 and thus effect electric connection from the positive pole through springs 11, 12 (also closed by the knob 5) to the lamp 46. To prevent this circuit from being closed when the counter is at zero the minute drum 18 carries a lug 57 to open the contacts 42, 43 at such time. A buzzer may also be sounded at ten seconds before and at the end of the three-minute periods by means of a contact 52 adapted to be engaged by the armature 16 at each rocking thereof.

Abstract: 1458252 Cold-cathode tubes; vacuum switches GENERAL ELECTRIC CO 28 Feb 1974 [2 April 1973] 9061/74 Headings H1D and H1N A vacuum arc discharge device comprises two circular arrays of parallel cylindrical coaxially aligned primary arc electrodes 16 and 18 supported in a sealed envelope by end plates 15 and 17, and an intermediate circular array of parallel electrodes 19 supported by an intermediate plate 13 which divides the envelope 11 into two regions A and B, and means 22, 23 for causing an arc breakdown between adjacent electrodes in each region A and B, the intermediate electrodes 19 being interdigitated with the primary electrodes 16 and 18 so that in operation adjacent electrodes are of opposite polarity and the magnetic force acting on current paths is minimized, thus minimizing the formation of destructive anode spots. The presence of two inter-electrode gaps in series in each conduction path between the terminals 43 and 44 of the device increases the hold-off capacity. Shield members 26 protect the insulating side walls 12 of the device from the deposition of metallic particles from the electrodes. In the device shown the arc initiating means comprise butt-type mating contacts 22, 23 mounted on a rod 36 and rods 33 sealed through bellows 34 protected by shields 35. In an alternative device (Fig. 3, not shown) the regions A and B are in communication through an aperture in the central plate 13 and the arc initiating means comprise a trigger electrode in one or both of the regions for injecting plasma into the inter-electrode gaps. In a further alternative device (Fig. 5, not shown) a trigger electrode is mounted in a bore communicating with the aperture in the central plate to inject plasma into both regions A and B.

Filed: 1926-04-08
Abstract: 259,481. Aktiebolaget Stern & Stern. Nov. 13, 1925, [Convention date]. Variable - speed gearing for electric condensers. A spindle 2 carrying the moving plates is connected to a tuning spindle 5 by means of eccentric mechanism. The eccentric is a spring wire 6<1> disposed in a groove 16 in, and soldered at the top to, the spindle 5. Journaled at its lower end is a wheel 7 urged by the wire 6<1> to engage the walls of a casing 3, 4 on the spindle 2. The casing is formed with conical walls with which the wheel engages, and by varying the distance between the conical parts, by screwing one relatively to the other, the gear ratio can be varied, the wheel 7 moving radially to allow of this. Secured to the wheel is an arm 8<1> extending through a hole 17 in the casing and slotted at 12<1> to engage a pin 13<1> on the frame. When the spindle 5 is rotated the wheel drives the casing round at a speed depending on the distance apart of the walls of the casing. Owing to the arm 8<1>, the wheel makes a small oscillatory rotating movement about its centre so that the drive varies cyclically in ratio. This pulsation can be compensated for by moving the hole in the wheel 7 to an eccentric position in that wheel.
