Title: Improvements in or relating to mechanical systems for transmitting control movements
IPC: B60K23/00
Filed: 1958-11-13
Abstract: 883,730. Bearings. LEDUC, R. Nov. 13, 1958 [Dec. 14, 1957], No. 36527/58. Class 12 (1). To eliminate static friction between a control rod 1 and a plain bearing 7 in which it is adapted to slide, the rod 1 is subjected to an oscillatory rotary motion by means of an electromagnet, having windings 14, 15 supplied with alternating current, and an armature 9 secured to a torsionally resilient bar 10 forming an extension of the rod 1. A control lever 12 imparts longitudinal movement to the rod 1. In a modification, the armature 9 is mounted on rod 1 and the magnet on torsion bar 10. In a further modification, the oscillatory motion is imparted by an electric motor 2, Fig. 3, having its driving shaft mounted at right-angles to the axis of the shaft 10 and carrying eccentrically loaded wheels 5, 6. Alternatively, the motor 2 may be secured to the rod 1. In another modification, a control rod 1, Fig. 4, is adapted to be displaced rotationally with respect to a bearing 7, and oscillatory motion is imparted by means of an electric motor 2 and eccentric wheels 3, 4 within the limits of lost-motion provided between the rod 1 and a control lever 12.

Title: Conveyor belts
IPC: B21L9/00
Filed: 1958-11-13
Abstract: 879,518. Endless conveyers. LANHAM, W. E. Nov. 13, 1958, No. 36601/58. Class 78 (1). [Also in Groups XXII and XXV] An endless conveying element comprises a series of transverse rods R each of which is provided with a pair of grooves G at each end, and pairs of links connecting these rods together at each end, each link being formed with a longitudinally extending slot S which comprises a wide central portion 52 to allow a rod to be passed axially through it and rounded ends S 1 of a radius smaller than that of the rods R but greater than that of the grooves G. The conveying element is assembled by first arranging links L on the rods R as shown, Figs. 2 and 3, and then passing the assembly through a pair of rotating anvils 17, 18 which compress the side portions of the links to reduce the width of the central portions of the slots sufficiently to lock the links within the grooves G. The side portions of the links on one side of the conveying element may be compressed more than those on the other side of the conveying element, e.g. when the conveying element is to traverse an arcuate path. The anvil 18 comprises a pair of discs arranged on a shaft 11 on each side of the conveying element, each disc having a series of anvils 20. The anvil 14 comprises a pair of plain discs 17 arranged on a shaft 10 at each side of the conveying element and a sprocket wheel 16 arranged between the discs of each pair which engages the rods R to draw the conveying element through the anvils.
Patent GB-344485-A (GB)
Title: Improvements in and apparatus for the manufacture and production of films and foils
IPC: B29C55/14
Filed: 1929-11-29
Abstract: Foils or films are formed from substances such as polymerization products of hydrocarbons of the butadiene series or of vinyl compounds, synthetic resins prepared by condensation of aromatic dicarboxylic acids with polyhydric alcohols, gelatine, rubber, and the like, by causing the liquefied substance to flow on to two diverging conveyer belts running at the same speed, in the neighbourhood of the vertex of the angle formed by the two said belts.  The film which is continuously produced in the gradually increasing area between the conveyer belts may subsequently be caused to pass over two belts which are parallel or nearly parallel to each other.  In Figs. 1 and 2, the film-forming substance flows from the hopper V on to the pulley a which <PICT:0344485/IV/1> <PICT:0344485/IV/2> <PICT:0344485/IV/3> <PICT:0344485/IV/4> carries the two belts d.  The formed film may be transferred to parallel belts e and again transferred if desired to another pair of diverging belts f, the purpose of the latter being to avoid the formation of irregularities in the film.  The film on the parallel belts may be subjected to drying, hardening or vulcanizing.  A pair of circular knives g are used to remove the film from the belts, the film being finally wound on a roller h.  By way of example, a solution of polymerized butadiene in cyclohexane may be fed from the hopper V, and the film formed, while on the bands e, is treated with sulphur chloride.  In Figs. 11 and 12 an apparatus is shown in which only one pair of belts is used to form and to carry the film during drying &c. The film-forming substance is caused to flow from a slot-shaped aperture p to the centre of the belts d, which are then caused to diverge by passing over two pairs of rollers l1 and l3, the two rollers of each pair being spaced slightly apart as shown in Fig. 12; the belts are parallel during the final run to the pulleys n.  Other suitable forms of apparatus are shown in which only one pair of conveyer belts is used.  In Figs. 7 and 8 (not shown) the conveyer belts are first caused to run parallel and close together, after which they diverge and then transfer the film which is produced on to another pair of parallel belts from which it is removed by passing on to a third pair running at a slightly higher rate, thereby subjecting the film to tension.

Title: Charge-coupled device
IPC: H01L29/768
Filed: 1974-08-22
Abstract: 1484275 Charge coupled devices PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 22 Aug 1974 [23 Aug 1973] 36951/74 Heading H1K In a radiation-sensitive charge coupled device, e.g. an image sensor, in which majority charge carrier packages are transferred along within the bulk of a semi-conductor layer 2 (Figs. 1, 2) of one conductivity type by the manipulation of potentials on a system of electrodes 12-18 coupled to the layer 2 capacitively via oxide layer 4 or via Schottky barriers, the layer 2 being such that it may be entirely depleted by the application of an electric field without breakdown occurring, excess majority carriers generated in the layer 2, e.g. due to overexposure to illumination, are drained away by the provision of a drain zone 19 of the same conductivity type as the layer 2 and separated therefrom by means which can form a potential barrier between the layer 2 and zone 19, which barrier is at least locally lower than that between successive potential walls in the layer 2. In this way overfilling of the potential walls, resulting in overflow of majority carriers and cross-talk between adjacent walls, is prevented by draining off the excess charges to the zone 19. In Figs. 1 and 2 the means separating the N type layer 2 and zone 19 consist of a P type isolation zone 7 extending right through the thickness of an N type epitaxial layer 22 in which the layer 2 is formed to an underlying P type substrate 21. The drain zone 19 is surrounded by the isolation zone 7 except at gaps 20 in the latter, in which gaps the relatively low potential barrier between the layer 2 and zone 19 is provided by depletion regions associated with the surrounding PN junctions. As shown an imaging array includes a plurality of parallel charge transfer layers 2, mutually isolated at their sides remote from respective drain zones 19 by further P type isolation zones 6 which, as shown in Fig. 2, need not extend fully through the epitaxial layer 22, an underlying region 23 thereof being pinchedoff by the adjacent depletion regions. The isolation zones 6, 7 also serve to drain minority charge carriers from the charge transfer layer 2. In this embodiment alternate electrodes of the system 12-18 are preferably of Al and polycrystalline Si. A modification of the configuration of the drain zone and the isolation zone 7 is illustrated in Fig. 8 (not shown). Fig. 10 shows a different arrangement in which the relatively low potential barrier between the N type majority charge transfer layer 42 and the N type excess majority carrier drain zone 59 (including N<SP>+</SP> zone 72) is provided in a channel region 60 by a field induced by a capacitive electrode 47. The operation of the Fig. 10 device is otherwise broadly the same as the first-described embodiment. Reference has been directed by the Comptroller to Specification 1,376,639.
