Title: Improvements in electro-magnetic contactor switches
IPC: H01H9/44
Filed: 1938-04-02
Abstract: 513,324. Electromagnetic switches. HEATON, F. April 2, 1938, No. 10119. [Class 38 (v)] An electro-magnetically operated contactor switch has a fixed contact M and a spring supported abutment m<1> which may be in electrical contact with M and is intended to buffer the moving finger F and prevent it bouncing when striking contact M. The buffer N prevents the finger F bouncing when the switch is opened. The finger F is pivotally mounted in bracket B<1> and the current passes through this pivot, good electric contact at the joint being obtained by the pressure of spring h' bearing intermediately of the length of finger F. The contact M and finger F are provided with adjustable tips that are serrated for engagement with M and F. The break of the circuit occurs in a field produced by an electromagnet having cheeks p, core P and series coil Q augmented by a permanent magnet P'. Two metal arc coolers R, R' are in the path of the arc and are so shaped that the length of the arc increases as the magnetic field blows the arc over the coolers. The coolers R, R' are in electrical contact with buffers m<1> and N. The chain lines show the position to which the coolers R, R' and associated equipment may be swung by rotating about the centre of core P for inspection of contacts. A stirrup is provided on the operating electromagnet to limit the off position travel of the switch. To assist inspection of contacts this stirrup may be released. The finger F is operated by the arm G by way of a pin H which may carry a nut h for adjusting the tension of the spring h'.

Title: Improvements in or relating to means for effecting simultaneous reproduction of motion and sound
IPC: G03B31/00
Filed: 1926-04-20
Abstract: 264,046. Brown, S. April 20, 1926. Differential speed indicators.-Relates to indicating-devices by means of which synchronous working of a kinematograph and a sound-reproducing machine may be effected, and particularly to apparatus of the kind described in Specification 27717/08, [Class 40, Electric telegraphs &c.]. The indicator, Fig. 2, comprises, a hand I<1> moved step-by-step by an electrical escapement, to which current impulses are transmitted by means of a make-and-break contact device D, E, operated by the spindle B of the sound-reproducing machine R, Fig. 1. The hand moves over an indicating member I which is rctated by gearing driven by the kinematograph projector C, the gearing comprising a worm M on a spindle L, which is connected by sprockets and a chain F to the mechanism of the projector. According to this invention, the worm M is splined on the spindle L, along which it may be moved to some extent in either direction by means of a fork U carrying a rack V engaging with a pinion X, the pinion being mounted on a spindle Y bearing a knob and an indicating pointer (not shown). The purpose of such movements is to correct for accidental variations in phase between the two machines, due, for example, to the reproducing needle being jarred from its proper position on the track. A scale over which the pointer on the spindle Y moves is calibrated to indicate phase differences, e.g. in terms of revolutions of the record. To correct for a known difference in phase, the pointer on the spindle Y is turned in either direction through the proper angle, thus altering temporarily the relative positions of the hand I<1> and its dial. The speed of the kinematograph is then changed until the necessary correction, indicated by the return of the hand I<1> to zero, has been brought about.

Title: Improvement in reaping and binding machines
IPC: A01D37/00
Filed: 1922-04-12
Abstract: 200,225. Davies, J. A. April 12, 1922. Reaping-machines.-To permit the machine to, operate while moving in either direction, a knifebar A<1> is fitted at' each end of the machine. A horizontal belt conveyer B extending between the knife-bars carries the cut crop to a binder C. A reel J is mounted on an arm M pivoted at N and adapted to be swung to the one side or the other of the machine in accordance with the operation of the cutters. The drive for the reel is from a power shaft E also connected to the travelling wheels; the rotation of the reel is thus reversed when the machine moves backwards. The knives are driven from eccentrics on a shaft H driven from the power shaft, one-direction clutches being fitted in the eccentric sheaves so that the appropriate knife only is driven for each direction of motion. For transport the reel is removed and the operating mechanisms for the knives and the conveyer are detached at the point U; the conveyer frame is then swung up about this point and secured to the tractor frame by straps. Reference has been directed by the Comptroller to Specification 19729/04.

Title: Improvements in and relating to photosensitive elements and processes of preparing photographic images
IPC: G03C1/73
Filed: 1956-04-05
Abstract: 792,438. Photographic elements and processes. DU PONT DE NEMOURS & CO.,  E. I. April 5, 1956 [April 20, 1955], No. 10498/56. Class 98(2). A photographic light-sensitive element contains a solvent-soluble phthalocyanine intermediate complex which on reduction gives an insoluble phthalocyanine pigment, and oxalic acid or alkali metal or ammonium oxalate or an a-hydroxycarboxylic acid or salt of the formula wherein Q is H, an alkali metal or ammonium, and R<SP>1</SP> and R<SP>11</SP> an hydrogen or alkyl, aryl, carboxyalkyl, hydroxyalkyl, carboxyhydroxyalkyi, polyhydroxyalkyl or carboxypolyhydroxyalkyl groups. The complex may be one of those described in specification 745,359 [Group IV(c)] or it may have the formula MPc (OR) n  X n  (where MPc stands for a metal or metalfree phthalocyanine molecule, X is Cl or Br, R is .an alkyl group and n is 1 to 4 and in which the metal may be Cu, Co, Ni, Cr, Fe, Mg or Na) or it may have the formula MPc(O.COR) 2  (where COR is an acyl group of a carboxylic acid having 2 to 7 carbon atoms). Such complexes are described in U.S.A. Specifications 2,662,895, 2,662,896 and 2,662,897. In certain of the examples a leuco calcium phthalocyanine is used, prepared as described in U.S.A. Specification 2,681,348. Hydroxycarboxylic acids specified are glycollic, glyceric, lactic, a-hydroxyisobutyric, tartaric, citric, mandelic, benzilic, atrolactic, gluconic, saccharic, mannonic, mucic and talomucic acids. A support such as paper or cloth may be impregnated with solutions of the complex and acid or its salts. Suitable solvents for the complex are methanol, ethanol, acetone, toluene, xylenes, chloroform, benzene, dioxane or ethylene glycol monomethyl, monoethyl or monobutyl ether. Alternatively a support may be first coated with a colloid (e.g. gelatin, polyvinyl alcohol or polyvinyl acetal) and then impregnated with the sensitizing solution or it may be coated with a mixture of an aqueous dispersion of the colloid and the solution of complex and acid (or salt). Exposure renders the acids or their salts reducing and the complex is thus reduced to insoluble phthalocyanine pigment in the exposed portions. After exposure, the unreacted complex is removed with a solvent or by treating with an aqueous solution of an acid, and a final treatment with aqueous ammonia may be given .

Title: Method and apparatus for combining video images with proper occlusion
IPC: G06T19/00
Filed: 1975-03-14
Abstract: 1495344 Television systems SINGER CO 14 March 1975 [24 May 1974] 10635/75 Heading H4F An arrangement for producing a two-dimensional display of an assumed three-dimensional scene when viewed from a selected view-point involves the use of sources of video signals representing respective objects in the scene, the signals being fed to the display in such a manner that portions of an object which are overlapped, as seen from the view-point, by another object are not displayed. As disclosed one object is viewed by a television camera, signals representing other objects being generated by digital image generators. A data processor determines a priority list for the objects, i.e. determines the order in which the objects are reached as seen from the view-point, the object nearest the view-point having the highest priority (Figs. 5-7, not shown). The display is on a cathode-ray tube. Each raster scan line in an object-representing video signal may provide count values indicative of the points where the line intersects the object. By reference to these count values and to the priority list during a display raster scan line, switching is effected to pass the relevant portions of the video signals to the display. Instead of using count values a priority circuit (Fig. 8, not shown) may be employed, priority-ordered bistables being set when a scan line meets an object and reset when it leaves the object, and the output of the highest-ordered set bi-stable causing the corresponding video signal to be displayed. Count values are used in the arrangement shown in Fig. 10. Video signals are provided by camera 140 and digital generators 146. The camera video signals are clipped and differentiated to give object-edge intersection pulses 168 which gate the count from a counter driven by line-synchronized clock pulses to the generators 142. Under control of the priority list from processor 134 the relevant digital image signals or the appropriately delayed video signals from camera 140 are fed via switch 148 to the display 138. The arrangement may form part of a flight simulator.
