In the embodiment described three wheels are provided, a second transfer device 23 being, located between the second and third wheels, the three wheels being driven at the same speed by a common electric motor (12) via sprockets (11) and drive chain (13) (Fig. 2, not shown). The transfer device comprise L- shaped arms (34), (Fig. 4, not shown) normally urged away from openings 35 by springs but operable under the action of a solenoid (40) to protrude through the openings and effect transfer of the objects from one wheel to another. The solenoid is excitable by means of a capacitor discharge circuit so that the transfer devices can only be positioned for a limited period of time. If the transfer devices are not appropriately positioned the objects enter lose holes 24, 25 that direct the objects via a return chute (27) to the opening 19. The chute (27) is normally blocked by a solenoid operated member either directly controlled by a coin release mechanism or by the fruit machine. If the objects are successfully manipulated to an opening 26 they operate the arm 33 of a microswitch to actuate pay out mechanism.

Title: Engine starters
IPC: F02N15/02
Filed: 1947-03-28
Abstract: 637,447. Turning-gear. BENDIX AVIATION CORPORATION. March 28, 1947, No. 8470. Convention date, May 15, 1946. [Class 7 (v)] In an engine starter mechanism comprising a motor and a starter clutch member 52 connected to the motor through a screw-and-nut device 46, 38 arranged to move the member 52 axially for engagement with a member 54 of the engine to be started and then impart a rotary motion thereto, the member 52 having an axial bore accommodating a mesh rod 62 which extends into the device 46, 38 the rod 62 comprises a shank portion 60 disposed within the axial bore and an inner portion 64 which is of larger diameter than the axial bore and constitutes a seat axially abutting against member 52 whilst an annular seal 72, fitted around the shank, is squeezed between the seat and the member 52 by clamping means 74, which may consist of a nut, securing the rod 62 to the member 52. When a shaft 36 is rotated by. the motor through speed-reducing means, a sun-gear 34 turns planet gear 30, carried upon a barrel 26, that in turn meshes with a fixed orbital gear 32 on the starter casing, so that by reaction the barrel 26 is rotated ; the latter, by means of multi-plate clutch 40, turns the nut 38. The screw shaft 46 is splined to the member 52, which latter is engaged by a combined oil seal and friction device 56, so that rotation of the barrel 26 causes the shaft 46 to move to the left and bring about engagement of the members 52 and 54. Upon further leftward movement of the shaft 46 being prevented by abutment of shoulder 78 and 80 on the shaft 46 and nut 38 respectively, the starter commences to crank the engine, which upon starting causes the member 54 to override the member 52. When the starter motor is de-energised the member 52 is cammed back to the position shown. Axial movement of the shaft 46 is transmitted to the jaw member 52 by means of the rod 62, the rightward shaft movement being limited by abutment with a flange 76 on a bearing sleeve 48 for the shaft 36. A spring 82 around the bearing sleeve 48 is contained between the rod 62 and a ring 84 in a groove on the shaft 46, the spring serving to both hold the member 52 and rod 62 in the position shown and to allow the former to yield axially when it initially engages the members 54. In order that the nut 74 may be removed or assembled to the rod 62 without a special tool for holding the member 52, the portion 64 of the mesh rod 62 is provided with flats which co-operate with similar flats in the shaft 46 when the latter is in its extreme right- or left-hand position. In a modification, the mesh rod is made hollow and of greater length than the previous mesh rod and encloses a spring, which replaces the bearing sleeve spring and has a flange that in conjunction with a nut, prevents complete separation of the jaw member and the screw shaft. The seal may be in a groove in either the jaw member or the mesh rod.

Title: Method and apparatus for the production of films having a plurality of components
IPC: H01B1/00
Filed: 1955-03-25
Abstract: 770,077. Coating by vapour deposition. STANDARD TELEPHONES & CABLES, Ltd. March 25. 1955 [April 3, 1954], No. 8857/55. Class 82(2). In a method of producing, by condensation in a vacuum on a receiving surface, a film having g a plurality of components, predetermined quantities of the components are introduced simultaneously to evaporators individual to the components and are evaporated spontaneously on introduction thereto, the vapours thus generated mix -together to form a gaseous mixture the composition of which is dependent on the said pre-determined quantities, and the gaseous mixture is subsequently condensed on the receiving surface to form a uniform film, the composition of which is also dependent on the said pre-determined quantities. By repetition of this process, a layer can be built up on the receiving surface as a succession of films. As shown a storage plate 1, having a ring of regularly-spaced perforations 2 for each component, is rotatable about a vertical axis and is carried above and just clear of a fixed retaining plate 3 which has an aperture, from which a channel 4 leads to an evaporator 5, for each ring of perforations 2, these apertures being so spaced that when, in one ring, a perforation 2 is directly over the aperture of the ring, then, in all the other rings, a corresponding perforation is also directly over the apprpriate aperture. Charges 6 of the components are placed in the perforations 2 and the storage plate 1 rotated until a perforation containing a charge is over the aperture for the ring whereupon the charge 6 falls into channel 4 and thus to evaporator 5. In three other modifications of the apparatus (a) a storage drum is provided which has rings of radially bored recesses for each component and rotates about its longitudinal axis within a cylindrical retaining sleeve which has an aperture for each ring of recesses, (b) a storage drum is provided which has a helix of recesses for each component, the drum being both rotated within the retaining sleeve and advanced along the axis of rotation, and (c) a flat storage plate is provided which has a row of perforations for each component and slides along a flat retaining plate which has an aperture for each row of perforations. The charge of a component may consist of one or more pieces of wire, a tablet, if the component is a powder, and,. if the component is a liquid, it may be contained in flasks which break on delivery to an evaporator. The evaporation of metals and chemical compounds is referred to as well as components which react in the vapour phase, and the method is stated to be suitable in the manufacture of films of Se compounds, e.g. cadmium selenide, for non-ageing Se rectifiers, in the reduction of the surface reflection of optical. glasses, and in the production of resistors and condensers.

Abstract: 657,062. Colour and stereoscopic kinematography. POOLE, R. B. March 31, 1948, Nos. 9049 and 33575. [Class 97 (i)] [Also in Group XL (b)] A projection viewing screen for colour, or stereoscopic colour, television or kinematographic image projection systems comprises a substantially continuous plane surface formed by the adjacent positioning of one face of each of a plurality of elongated triangular members, the different faces of each of which carry a plurality of colour elements, means being provided for causing intermittent and simultaneous rotation of each of the triangular mem. bers about an axis such that the different faces of each of the members successively and simultaneously occupy the adjacent positions which form said plane surface. In the described embodiment the members TR (Fig. 1) which are of equilateral triangular section and the different faces of which are provided with a repeating series of red, green and blue (R.G.B.) colour reflecting strips, the order of which is different for each face, are supported in a frame member for rotation about axes 1 parallel to the long dimension of each member and are so positioned that a substantially continuous plane multi-colour surface comprising one face of each member may be formed. In order to change the colour sequence of this surface each member TR is rotated, about axis 1, through an angle of 120 degrees by means of a worm thread spindle 3 (Fig. 3) which engages pinion gears 2 secured to member TR and which is driven, via a gearing system 19, 20, by means of a ratchet mechanism comprising a ratchet-gear RG and a co-operating pawl AL, the diameter of the ratchet gear and the ratio of the gears 19, 20 being such that the members TR are rotated through the desired angle of 120 degrees for each operation of the pawl. When the screen is employed with kinematographic colour image projection apparatus the rotation of the members TR is synchronized with the operation of the projection apparatus by means of a switch controlled by the latter apparatus and connected in the power supply circuit 129 to the solenoid IMa which is thereby momentarily energized during the film "pull-through" interval, this energization producing a single " kick " of the pawl. The remaining electrical elements shown in Fig. 2 are not employed when the screen is used with kinematographic image projection apparatus. It is stated that images of stereoscopic character giving the impression of depth may be produced by employing in the projection apparatus a film produced by means of a kinematographic film camera in combination with the optical system described in Specifications 629,594, [Group XL (a)], and 592,375, and by causing the screen colour sequence to be changed between the projection of successive images which form stereoscopic pairs. Constructional details of a frame mounting for the members TR are described with reference to Figs. 4 to 9 (not shown). Specification 657,060, [Group XL (a)], also is referred to.
