Abstract: 1,027,629. Cine film cassettes TECHNICOLOR CORPORATION OF AMERICA. Oct. 17, 1963 [Oct. 19, 1962], No. 39625/62. Heading G2E. [Also in Divisions B6 and G5] In a cassette for an endless 8 mm.film or other recording strip, in which the film is coiled in spiral form 32 with a loop passing from the inner to the outer convolution, the film 18 is coiled on a cylindrical core 16 which is rotated at a peripheral speed not less than the linear speed of the film drawn from the inner convolution. The cassette, which may be of plastics material such as Perspex (Registered Trade Mark) comprises a cylindrical casing 10 with an extension 11 at one side and has a spindle 12 on which is journalled the core 16 overlying a disc 15. A disc 19 retains the film coil on core 16 and has a central aperture of greater diameter than that of core 16 through which the film passes. The inner edge 21 of this aperture is partly received by a groove 20 in the core 16 and is partly guided by flanges 22, 23 of rollers 24, 25 on cover 28 of the case 10. Film from the inner convolution of coil 32 passes under roller 24, over roller 25 and then round the friction surface, which may be rubber, of a drum 30, before passing round the drum 34 rotating on spindle 35 and driven by contact with driven rollers through slots 36 in cover 28. The drum 30, which has a diameter slightly less than that of core 16, is driven by the motion of the film, and rotates core 16 through the driving connection of a spiral spring 33 secured to the core by a peg 29 and to the axis of the drum. From the drum 34, the film passes through gate 44 and returns to the outer convolution of coil 32. The rotation of core 16 avoids the build-up of tension in the coils of the film spiral. A sound pick-up 37 is provided.

Title: Lever control assembly
IPC: B60K26/02
Filed: 1974-09-18
Abstract: 1489426 Linkwork; Bowden mechanisms; change-speed control TELEFLEX Inc 18 Sept 1974 [18 Sept 1973] 40685/74 Headings F2K and F2D A control lever 26 transmits motion to means such as a Bowden cable through a member 24 which is rotatably supported in a housing 22 by bearings at its opposite sides and has a compartment between the bearings accommodating one end of the control lever, the member 24 being so formed that the lever may be coupled to it rigidly or in a manner to allow lateral pivotal movements of the lever. In the latter case the lever is spring biased, e.g. by a spring 52, and operates in a stepped slot in a plate 28. The apparatus may be employed for throttle and/or transmission control in small marine craft or in earth moving vehicles. As shown, both the member 24 and the housing are formed by identical halves 32 and 74 bolted together, and the bearings are constituted by stub shafts 62 on the halves 32 received in bores 64 in the housing halves, but the stub shafts may alternatively be formed on the housing halves to be received in cavities in the halves 32. A circuitous path for excluding foreign matter from the bearings is provided by interfitting annular formations 66, 68. When the lever is to have lateral pivotal motion relatively to the member 24 it is connected thereto by a single pin 46, Fig. 4, received in two pockets 48 in the member 24, but when a rigid connection is required a second pin received in pockets 481 is used. As an alternative to the spring 52 a spring-loaded plunger (not shown) mounted in the member 24 may engage a tapered and rounded end of the lever, this arrangement enabling the lever to be biased to either side of its central position. Each housing half is formed externally with a series of threaded holes 86 and channels 92, 93 ... 99 whereby a conduit support means 78 comprising a pair of parallel legs and a clamping bracket 84 may be secured in a variety of positions. The motiontransmitting core, movable within the conduit, is connected to the member 24 by means 42 received in any opposed pair of a series of holes 40 in flanges 36 of the member 24. Holes 102 in the housing halves provide for the fixing of brackets 106 which rigidify the structure and may carry one or more switches for actuation by the flanges 36. Movement of the lever may be controlled by friction or locking means, e.g. by a pin (not shown) projecting from the member 24 and spring-biased to ride over ridges on a fixed plate. The pin may be mounted so as to engage the ridged plate only when the lever is pivoted laterally.

A line-at-a-time printer wherein a line of characters is formed by selectively printing a number of lines of marks, means are provided for urging all the printing elements 1 towards an impression surface and further means for holding back selected elements. As shown, the elements 1 are pivoted on common shaft 2, and energization of a magnet 5 tends to move them all to printing position. The upper end of each element has a part 8 inserted with small clearance in the gap between two foils 9 of insulating material. Conductive foils 10 are situated between the foils 9 and other insulating foils 11. The pair of foils 10 is electrically connected to a metal block 12 with a terminal 13, the terminals of the various blocks being staggered as shown. In operation, a switching wheel connected to the paper-feed shaft causes energization alternately of the magnet 5 and a resetting magnet 6. The foils 10 of elements 1 which are not required to print, are energized, and the electrostatic force set up holds those elements back when the magnet 5 is energized. Instead of foils 10, there could be metal coatings on the foils 9. Also, the electrostatic device may comprise stampings suitably coated with insulating lacquer. In a modified construction, Fig. 4 (not shown), the part 8 performs a lateral movement instead of an endwise movement.
