Title: Improvements in and relating to cinematograph projectors
Inventor: TOLE DONALD KENNETH
IPC: G03B9/10
Filed: 1951-05-10
Abstract: 703,179. Kinematograph apparatus. SPECTO, Ltd. Aug. 8, 1952 [May 10, 1951], No. 11035/51. Class 97(1) In a projector a motor driven shutter shaft is surrounded by a concentric tubular shaft from which the intermittent feed mechanism is driven, a clutch being provided for releasably coupling the two shafts. As shown, the shaft 10 for the shutter 11 is driven by a motor through gearing 12 and a belt 13. The concentric tubular shaft 14 carries a constant diameter cam 16 embraced by a follower 17 which drives the feed claw. A worm 19 formed on the shaft drives the sprockets 20, 21. The clutch between the two shafts comprises lever 22 (Fig. 2) pivoted at 23 on a flange 14a on the shaft 14 and normally urged by a spring 25 to engage a tongue 22a in a notch in a collar 24 fast on the shaft 10. A stop 26 can be pivoted about an axis 38 into the path of the lever 22 to pivot it and to retract the tongue 22a from the notch and then to engage the projection 22b to arrest the shaft 14 positively. The lever 22 is biased by a spring 40 to a position where it engages the lever 22 but can be removed by manual operation of a lever, 30, anticlockwise against the action of a spring 49, to actuate a forked lever 34, pivoted at 35, carrying a pin 37 which bears on the extension 39 of the lever 22. The lever is moved until a projection 39a is engaged by a pivoted latch 42. The latch can be released, by the action of the pin 36, on the lever 34, when the lever 30 is rotated clockwise for example by the loss of a film loop so that the film bears on the roller 28 at the end of the lever 30. A heat filter (not shown) is carried by a sleeve 46 frictionally engaged with the shaft 14 and is lifted by the friction force out of the projection light beam only when that shaft is rotating. According to the 'Provisional Specification a roller similar to 28 may be provided in the film loop above the gate. Also, the clutch for engaging the hollow shaft to the shutter shaft may be as described in Specification 652,616. Specification 678,661 also is referred to.

Abstract: 832,335. Lens adjustment devices for stereo projectors. KODAK Ltd. April 8, 1958 [April 9, 1957], No. 11035/58. Class 97(2) A stereo projector, with lens adjustment means, has one lens rigidly attached and the other attached by two movable members to a support so that by movement of said members relative to each other and to the support the second lens may be moved relative to the first in any direction in a plane orthogonal to the axes of the lenses. In the stereo projector shown a lens 15 is rigidly attached to the wall 12 and lens 17 is attached to the wall by twomovable plates 21 and 22 held in place by 'springs 23 and with ball bearings interposed between the two plates and between plate 22 and the wall. Lens 17 can be adjusted relative to lens 15 by rotating a rod 45 about a universal pivot 47 thereby moving plate 21 vertically relative to plate 22 and the wall 12 and both plates horizontally relative to the wall, as required. Plate 22 is prevented from moving vertically with respect to wall 12 by means of a rectangular hole 49. The wall 12 is part of a support 11 and to focus the lens 17 this support may be rotated, by means of a rod 65 about an axis indicated by 72, the focus of lens 15 being unchanged if the axis of rotation passes through one of the nodal points of lens 15. To focus both lenses simultaneously support 11 can be moved horizontally in the direction of the axes of the lenses by rotating the rod 65 about its own axis. Specification 832,336 is referred to.

Title: Improvements in and relating to conveyors
IPC: B65G17/10
Filed: 1945-05-03
Abstract: 628,319. Rope-driven conveyers: NAYLOR BROS., Ltd., and VALLANCE, B. May 3, 1945, Nos. 11208 and 32085. [Classes 78 (i) and 78 (ii)] A conveyer plant in which an endless belt conveyer is driven from and may derive support at both edges from two lengths of rope running in the same direction adjacent opposite margins of the same run of the belt and forming part of the same continuous driving rope, by means of transverse U-shaped supports which are secured to the belt at spaced intervals and which have box heads mounted on opposite ends thereof, each boxhead including gripper jaws which are adapted to engage and grip the rope and which are directed inwardly from the boxheads towards the conveyer so as to support the margins of the belt and thus to impart a troughlike cross-section to the belt. Figs. 4 and 10. Conveyer belt 30 passing around idler pulleys 67, 76 is driven by wire rope 51 which passes over driven pulleys 68, 69 and over skew pulleys 24, 25 so that each conveyer run is driven from two. lengths of the same rope. Belt 30 is secured at intervals to hanger 31, Fig. 14, which is fixed to a boss 50 on boxhead 32 carrying wheels 36. On the boxhead 32 are jaws for clutching the rope which jaws have members 40 slidable in slides 39 of the boxhead and pivotal members 43 pivoted at 47 to links 48 which are pivoted at 49 to projections on boss 50 of the boxhead. When wheels 36 having traversed the upper run of the conveyer meet rails 80 the jaws disengage themselves from the rope owing to relative movement between member 40 and jaw 43 caused by transfer of weight from rope 51 to rails 30 and the wheels are then carried by the belt round belt pulley 67, and run on to rails 83. Rails 83 bend upwards at 87, Fig. 5, as the twin lower lengths of rope temporarily diverge over pulleys 89 to allow boxhead to rise above rope and engage it at 85 with its other pair of jaws. Depression plates 115 assist the engagement of the rope with the jaws. The disengagement and re-engagement of the jaws with the belt operates similarly at the non-driving end of the belt. The tensioning of the rope may be adjusted by the device indicated at 75, Fig. 10, in which the frame comprising the pulleys 24, 25 is adjusted on rails 121. Similarly the belt tension may be adjusted by device 70 through pulley 67, Fig. 4, or by device 77 through pulley 76, Fig. 10. Each pair of rails for supporting wheel and boxhead is adjustable in length at 112, 113, Fig. 4, and 110, 111, Fig. 10.

Abstract: 1,086,987. Counting-apparatus. SIEMENSSCHUCKERTWERKE A.G. March 17, 1965 [March 17, 1964], No. 11409/65. Heading G4D. Metering impulses at magnet 6 oscillate an escapement to permit a synchronous motor 1 to drive a total register 9 through a clutch 3. Each impulse also drives a storage device 11 comprising a series of idle-motion discs. The device 11 acts on one sun-wheel 14 of a differential gear 15. Initial movement of the associated planet wheel and cardan shaft 30 frees a stop member 32 from an arm 33 which then makes one revolution, driven by the motor 1 through a further clutch 20. This drives the other sun-wheel 16 to restore the step member 32. Each revolution of arm 33 adds one to a maximum-demand meter 23. At the end of a metering period the total on 23 is printed and meter 23 zeroized. During the printing operation a device 24 engages arm 25 to prevent rotation of arm 33. Incoming pulses are then stored in the idle-motion discs of device 11 and in spring 31. When printing is complete the stored impulses are entered by the appropriate number of rotations of arm 33 into meter 23.
