Title: Control apparatus for a closed transport system
IPC: B61L3/22
Filed: 1972-07-26
Abstract: 1411637 Vehicle control H JUNGHEINRICH GmbH & CO KG 26 July 1972 [29 July 1971] 34957/72 Heading B7N [Also in Divisions H4 and G4] In a transport system, e.g. a railway or leader cable system, each route junction, which allows choice of two directions of travel, is provided with a transmitter which transmits a signal indicating the direction a vehicle must take at the junction to proceed towards any destination in the system. This signal when received on a vehicle approaching the junction is compared with its stored destination to control movement of the vehicle over the junction. The system can comprise a number, e.g. 4 track networks each, e.g. network 3 including a number of destination zones 1-12 and a number of two way track junctions, divisions or points W1-W12. Each transmitter transmits a first word each bit of which indicates the position, O (left) or L (right) the junction or division must be in to route a vehicle towards a particular network, in addition the first word indicates the network in which the junction is positioned by marking the bit associated with the network, e.g. network 3. The first word is followed by a second each bit of which indicates the division or junction position to route a vehicle towards a particular zone in the network containing the division or junction. Where the junction gives immediate access to a zone, e.g. junction W8 to zone 10, the associated bit is marked. A third word can be transmitted defining a stop position in the destination zone in terms of the number of track markers (not shown) which have to be counted between zone entry and the stop position. The O and L bits are transmitted as short or long pulses and are marked by an immediately following long pulse. In the leader cable arrangement shown including cable sections 101, 102 leading to division or junction 104, transmitter 128 energizes floor antenna 127 in advance of the junction with the three word signal and the signal can be picked up by antenna 174 on an approaching vehicle and applied to a seriesparallel converter 131 and distributer 140. The converter output is applied to comparator 133 where it is compared with the vehicle network and zone destination stored in memory 130. The distributer 140 controls the programming of the vehicle apparatus whereby initially the comparison of the first word with the network destination stored provides an output via memory 135, decoder 173 and output transmitter 145 to control via coil 111 and floor reed switch 110  the leader cable section to be energized at the junction 104 and when the required network is reached then the second word is compared with the stored zone destination to control the junction switch via logic unit 136, memory 148 and decoder 173. When the destination zone is reached the third word is used to control the stopping of the vehicle in the zone.

The minor filament and the shield are laterally offset a slight distance from the vertical axial plane of the reflector. The lamp shown is of the sealed beam type but separate lens and reflector members and a separate incandescent lamp within the reflector may be used. The filaments 7, 8 are supported on cranked lead-in wires 9, 10 and 11, 12 extending through the envelope and secured to three symmetrically arranged metal thimbles 14, 15 fusion sealed into the envelope. The wires 10, 12 are both led to one of the side thimbles. A leg or support 26 for the shield 20 is fastened to the lead in wire 12. The lens 3 is divided into horizontal sections A to F having vertical side-byside flutes on the inside thereof. Certain portions of each section are formed with either upwardly, downwardly, left or right bending prisms according to a prescription given in the Specification. The form of shield 20 shown in Figs. 2 and 3 has a semi-cylndrical top wall 21 and plane bottom wall 23 inclined at upwardly and forwardly about 35 degrees to the horizontal. The rear edges of these walls are in a vertical plane slightly in front of the minor filament (say 1.3 mm.). The rear edge 25 of the bottom wall is level with or slightly below the lower side of the minor filament 7. The front portions of the walls 21, 23 meet in a corner portion 24. In a modification the shield is in the shape of a quarter of a sphere and its plane bottom wall is horizontal. In a further modification, the shield has approximately the same form as shown in Figs. 2 and 3, but its upper wall is formed with a laterally off-set upstanding fold through which passes a straight lead or support such as 26 inclined downwardly and forwardly at a shallow angle. The fold is crimped to this support in its adjusted position. The filaments instead of being linear coils as shown may be arcuate or V-shaped.

Title: A method for printing faked films and photographic projection printing machine for the performance of said method
IPC: G03B27/475
Filed: 1946-11-26
Abstract: 651,964. Photographic projection printing apparatus; producing composite photographs. COUTANT, A. C., and MATHOT, J. Nov. 26, 1946, No. 35071. Convention date, Dec. 13, 1945. [Classes 98 (i) and 98 (ii)] A method of printing faked films composed of records or views previously recorded on two or more separate original films comprises printing a first original film on a blank by the steps of successively projecting the images on the first original film through a mask bearing negative silhouettes which are identical in shape, size, and outline with the images on the first original film, obtaining during intervals of the projections of these views images thereof upon a translucent screen, arranging a second original film adjacent and parallel to this screen, feeding successive frames of the first original, blank, and second original films simultaneously, observing through the second original film the image of the first original film on the translucent screen, and adjusting the films and the mask to effect registration between the image of the first original film and the second original film. Thereafter the two original films may be interchanged and the mask replaced by a mask bearing negative silhouettes of the images on the second original film. The masks may be in the form of a film which is fed forward in synchronism with the original and blank films, and the projected image of the original film may be directed by a reflective moving shutter alternatively on to the blank film or the translucent screen which may be observed through a magnifying system. As shown, to produce a composite picture of a cinema audience viewing a film from a film 5 of what the audinece is shown and a film 4 of the audience looking at the screen, the film 5 is placed in a projection chamber 8, a mask comprising an opaque film bearing transparent silhouettes identical in shape, size and outline with the images on the film or a similar metal stencil-plate is placed at 20 and, if desired, at 25, and the image projected by the lens 21 is formed after reflection from the shutter 11 on a translucent screen 22 behind a gate 17, the screen being backed by the film 4. The image formed on the screen 22 and the film 4 are projected by lens 23 and mirror 24 on to a viewing screen 14 so that the operator is enabled to effect registration of the two images before he opens the shutter 11 to print the image of film 5 on the blank film 6 in the gate 16. If it is desired to have several viewing systems, to transfer the viewing point elsewhere, or to check the registration of the film being projected with several other component-film registration control screens, additional reflecting shutters may be located in the path of the exposing beam to the film 6 and successively displaced to permit viewing of the projected image on the several screens such as 14.

Abstract: 895,284. Automatic voltage control systems; rectifying. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. Nov. 5, 1959 [Nov. 5, 1958], No. 35538/58. Classes 38 (2) and 38 (4). In a direct voltage control system, a load 29 is supplied from a transformer 35 via germanium diodes 37, 39 and transistors 31, 33 connected as shown. The base currents to the transistors are derived from a centre-tapped secondary of a transformer 13 energized by the output of an auto-self-excited parallel transductor 1. Control windings 17, 19 of the transductor are energized from a direct current source 21 and opposing feed-back windings 23, 25 are energized from across the load. The resultant flux, due to the control and feed-back windings, causes a variation of the period in each halfcycle for which base current flows, tending to maintain the load voltage constant. Positive biases applied to the bases of the transistors during the periods of low base current from a transformer 45. A resistor 15 absorbs the small magnetizing current through the transductor during the periods of low base current. Rectifiers 7, 9 are silicon diodes. The feed-back is set by a rheostat 27.

Abstract: 1481742 Producing multicolour effects on textile materials HOECHST AG 16 Aug 1974 [16 Aug 1973] 36247/74 Heading D1B Irregular tone-in-tone effects, shadow effects, or multicolour effects are produced on a textile material consisting of or containing polyester fibres, by applying to warps of the textile material a water-insoluble alkali-sensitive disperse dyestuff, drying the warps, then weaving them with a weft which is undyed or dyed in a different manner, binding the piece goods obtained together to form a rape, loosely tying them and applying to the material in rape form an aqueous solution of an alkaline agent of pH 10.5-14 which is free from oxidising and reducing agents, so as to prevent substantially the subsequent fixation of the disperse dyestuff in the areas to which the alkaline agent is applied, and finally thermosoling the material after untying the rape, to fix the dyestuff. Materials used are polyester and polyester/cotton. The alkali-resistant dyestuff is preferably applied by padding with the sizing liquor applied to the warp. The alkaline agent, particularly an alkali metal hydroxide, carbonate, or triphosphate, is preferably applied by spraying. Fixing is preferably by dry heat at 180-230C. In a modification of the above process, the alkali-sensitive dyestuff is applied to the fibres after weaving, the piece goods are dried, and then subjected to alkali treatment in rape form. Other dyestuffs used to obtain multicolour effects are reactive dyes and alkali-resistant disperse dyes.
