Title: Machine for printing films for coloured motion pictures
IPC: G03B27/08
Filed: 1920-07-10
Abstract: 148,463. International Moving Picture & Film Co., (Assignees of Hunt, J. R.). June 16, 1919, [Convention date]. Kinematograph apparatus.-Relates to apparatus for printing positives from a colour negative having a recurring series of red and green pictures, and comprises means for guiding the films so that accurate register is obtained. Two printing gates are provided and the positive is printed in such a manner that the first few red pictures are printed in one gate with intervening blanks, and subsequently successive red and green pictures are printed at the two gates. The negative 31, Fig. 2, and positive 30 are fed together from the spools 27, 26 by the feed sprocket 32 and then pass over separate loose sprockets 132, 232 and through separate guides having means for keeping the films in register laterally, to the printing aperture 36, through which they are drawn together by clawfeed mechanism 70, and then pass through further guides which also provide for lateral registration. A second set of sprockets and guides and another feed mechanism are provided tor passing the film through the lower gate 137, all the mechanism being driven from a common shaft 22 itself driven by a motor at the bottom of the case 20. Each loose sprocket 132, 232 is secured on a shaft 233, Fig. 9, rotating in the side of the frame 234 and controlled by a spring-pressed friction washer 235. One flange 239<a> of the sprocket is fixed and the other flange 239 is movable and presses on the edge of the film under the action of the spring 240. The separate guides for the films 31, 30 are constituted by a base-plate 100, Fig. 6, an intermediate wedgeshaped plate 106, and a front plate 109 pressed by a flat spring 110, Fig. 3. The base-plate 100 has a fixed side flange 101 and a spring-pressed movable flange 102 engaging the outer edge of the negative film 31. The intermediate plate 106 serves as a base-plate for the positive film 30, and the pressed plate 109 has a movable spring-pressed side plate 111 engaging the edge of the film 30, and pressing the other edge against the fixed flange 101. After being fed through the upper printing aperture 36 by the feed mechanism 70 the films pass together through guides constituted by the fixed flange 101, Fig. 5, and two movable plates 115, 116, pressed by springs 119, 120 against the edges of the two films, and the edges of the films are pressed on to the base 100 by the shoes of the spring-pressed plate 121.

Filed: 1943-12-09
Abstract: 574,890. Motor-cycles ; driving-gearing. HARRISON, C. H. Dec. 9, 1943, No. 20602. [Classes 79 (ii), 79 (iii) and 79 (v)] A self-contained power unit for a pedal cycle or the like comprises a carrier member or plate 1 supporting an engine 2, a friction roller 9 driven by the engine and adapted to be moved into and out of driving engagement with the road wheel 7 by movement of the carrier member about its supporting links 3, 4, is characterised in that means provided for positively locking the power unit in both the driving and non-driving positions comprise a rigid strut 13 connected at 14, 16 to the carrier and an operating lever 21 and sliding and locking mechanism 19, 20 to permit relative movement between the strut and lever when the latter is operated and to lock them together when in the adjusted position of the unit. In the construction shown, the carrier member 1 is connected to the cycle frame by links 3, 4, the link 3 being adjustably fixed at 21B to a lever 21 on which slides a handle 17. The strut 13 is clamped at 14 to the engine and is pivoted at 16 to .the handle 17, so that as the handle and lever 21 are moved up or down to engage and disengage the driving gear, the handle is slid on the lever by the strut 13 and the power unit can thus be locked in any desired position by securing the handle and lever together. This is effected by means of a rotatable block 19 having teeth 20 carried by the handle 17 and adapted to engage the rack teeth and thus lock the handle to the lever. The block 19 is rotated to engage and disengage the teeth 20 by pressure on a button 18. When the friction roller is disengaged from the cycle wheel, the engine is prevented from racing by means of a compression-release valve 23 operated by a link 22 connected with lost-motion 25 to the link 3. A centrifugal governor may be provided on the engine to limit the speed of the cycle. Specification 476,369 is referred to.

Abstract: 902,051. Cooling brakes. ALBION MOTORS Ltd., and KEMP, J. A. May 19, 1961 [June 11, 1960], No. 20620/60. Class 103 (1). [Also in Group XXXI] A motor vehicle wheel braking mechanism includes a fan rotor coupled to the wheel by a gear train of ratio greater than unity, ducting being provided between the fan and the braking mechanism. As shown in Fig. 1, a wheel 9 having tyres 10 is coupled to a brake drum 8 mounted for rotation on a sleeve 5 supported by bearings 6 on the axle casing 7. The drive from the half-shaft 1 is transmitted through a sun-Wheel 2, planets 3 and a planet-carrier 4 to the hub 5, the planets 5 also engaging a toothed ring 3A which is also engaged by a toothed ring 3B connected to the casing 7. The fan rotor 11 is connected at 12 to the half-shaft 1 and a duct 13 is provided to direct air to or from the brake drum 8 according to the set of the blades. In Fig. 2, a fixed stub-shaft 14 carries a wheel 19 by means of a hub and bearings 20. A sun pinion is mounted on the shaft 14 and meshes with planets 17 carried by a carrier 18 attached to the wheel. The pinions 17 also mesh with a toothed annulus 17A fixed to the shaft 14. The sun 16 is rigid with a fan rotor 22, the blades 23 of which are located in a shroud 24 and direct air in or out, according to their setting, of a duct 25 and past a brake disc 21 rigid with the wheel hub. Because the planet carrier 18 rotates with the wheel, the pinion 16 and rotor 22 rotate at a greater speed.

Title: Improved apparatus for testing the accuracy of toothed gears
IPC: G01B5/20
Filed: 1933-07-24
Abstract: 417,151. Gauging toothed gears. TRY, W. H., Old Bridge Cottage, Staines, Middlesex. July 24, 1933, No. 20827. [Class 106 (ii).] Comprises a rotatable support for carrying the gear to be tested and an annulus fixed concentrically on the support and having rolling contact with an element carrying a detector pivotally mounted and adapted to make contact with a gear tooth and to actuate directly indicating mechanism, the contact element being slidably carried on a fixed support. A gear supporting spindle 2 is freely supported on roller and thrust bearings in a base 1. A slide 6 mounted on the base 1 so as to be moved by a screw 9 supports a contact element 7. The latter is slidably mounted on roller bearings in the part 6 and is forced into engagement with an annulus 15 fixed on the spindle 2 by means of a spring 12 acting on the spindle 9. Above the annulus the gear to be tested is mounted on the spindle 2. Carried on a base secured to the contact element 7 is the indicating mechanism 22 and detector 23. The latter may be adjusted towards or away from the spindle 2 by means of a knurled nut 26 held between lugs on the base and moving a screw 25 fast with the indicating mechanism 22 which is mounted in guides. A mark 28 on a projection 27 registers against a scale 19. The detector 23 with its feeler point 23<a> is pivoted about a vertical axis and its shank engages between the plungers 32 of two dial indicators 30. To improve sensitivity the detector shank also passes between two spring plungers 34 having collars 35 which limit their movement towards the shank. When the latter moves from a central position, one of the plungers is moved against its spring. This assists in returning the shank and the other plunger prevents over movement. A micrometer adjustment 21 is provided for the scale 19 which permits the distance rolled by the contact element 7 on the annulus 15 to be read off. The annulus is not necessarily circular, but may be of any predetermined shape and the contact element may be provided with a curved edge instead of a straight one. When testing opposite faces of teeth the scale must be readjusted to zero.
