Abstract: 643,731. Tape dispensers. BETTER PACKAGES, Inc. Aug. 7, 1947, No. 21706. Convention date, May 9, 1942. [Class 18] The length of adhesive tape delivered from a dispenser is selectively controlled by electrical means. The tape is led from its supply roll 28, resting on a braking plate 33 and roller 34, round a guide roller 31 and between two guide plates 35 on to a table 50. It then passes beneath a forked tape weight 53, between the fork of which is mounted a roller 60 supported between links 71 connected to a solenoid 77 and biassed by springs 80. A slot 51 is provided in the table 50 to permit a roller 61, driven from an electric motor 27, to co-operate with the roller 60, when the solenoid 77 is energized, to engage the tape and deliver it past a severing device 94 and over moistening brushes 111. The cutter blade of the severing device is mounted between links 90 attached to a solenoid 98 which is actuated to enable the tape to be severed. When it is desired to actuate the dispenser, the electric motor is connected to a source of power so that the roller 61 is driven continuously. A bank of selector switches is provided in the top of the dispenser each of which controls mechanism to enable a predetermined length of tape to be dispensed. By actuation of a switch a starter relay is operated and the solenoid 77 is energized to pull the roller 60 on to the tape and press it against the driven roller 61 and effect delivery of the tape. Depending on the switch operated, a number of resistances are included in a circuit and these determine the period for which it is required to charge a condenser to the breakdown point of a cathode tube at which point a stop relay is operated and breaks the circuit including the solenoid 77, and feeding of the tape ceases. At the same time a circuit including the solenoid 98 is energized and effects severance of the tape. A bar holding the switch in its operative position is simultaneously withdrawn and the switch returns to its inoperative position.

Title: Improvements in or relating to cathode-ray devices for television and the like
IPC: H04N5/257
Filed: 1933-08-04
Abstract: 423,247. Television. WEST, A. G. D., and BAIRD TELEVISION, Ltd., 58, Victoria Street, London. Aug. 4, 1933, No. 22016. [Classes 39 (i) and 40 (iii)] The deleterious effect of saturation of a luminescent screen 2 in a cathode-ray tube 1 is overcome by increasing the normal area of incidence of electronic flux on the screen and reducing optically the effective size of the resulting luminescent area. A streak is formed on the screen at right angles to the direction of scanning by the use of a rectilinear cathode or by rapidly traversing the light spot at right angles to the direction of scanning. This traversal may be simple harmonic, but the scanning traversal is produced by a saw-tooth wave. The streak is concentrated to a scanning spot 7 by a lens 3 which concentrates the light more transversely to the scanning direction than in the scanning direction.

In an aircraft having a thin wing 1 each land wheel 4 is mounted on its undercarriage leg 5 in a manner which enables it to be housed within the fuselage 2 in an inclined position adjacent a power plant 3. The leg 5 is mounted on the wing 1 by a pivot 6 and it is retracted sideways by a jack 33 connected to the fuselage at 34 and to the leg at 37. The lower end of the leg carries a fitting 8 pivoted thereto on an axis II and having an extension pivot 12 on an axis III for a fitting 9 which has stops 11 co-operating with the member 8 to limit its rotation about axis III. The fitting 9 carries a wheel axle 10 on axis IV and an oppositely directed extension 16 on axis V forming a mounting for a shaft having levers 18 and 22 at its opposite ends. Lever 22 is connected to a spring loaded locking pin 21 which co-operates with a recess 24 in fitting 8 to prevent relative rotation of fitting 9 and lever 18 is connected at 20 to a universal joint on the lower end of a telescopic tie rod 39, said rod having a universal connection 38 at its upper end for attachment to the wing on an axis IX located outboard of the pivot 6. The fitting 9 carries also a lug 30 for the attachment of the lower end of a shock absorber 28. During initial retraction of the leg the tie-rod 39 extends to its limit and subsequent retracting movement first causes levers 18 and 22 to rock about axis V thereby freeing the pin 21 from recess 24 and secondly causes fitting 9 to rock about pivot 12 up to the limit set by stops 11 when the wheel axle 10 lies on axis IVa with the leg and wheel in its fully retracted position. A further embodiment, Figs. 10 and 11 (not shown) concerns a similar arrangement with the shock absorber housed co-axially withiri the main leg.
