Title: Improvements in or connected with motion picture screens
IPC: G03B21/56
Filed: 1927-11-16
Abstract: 281,280. De Forest Phonofilms, Ltd., (Assignees of Forest, L. de). Nov. 27, 1926, [Convention date]. Projection screens are constructed with passages therethrough so that they have an apparently continuous picture display surface but sounds may be transmitted through them; loud speakers may be arranged behind the screens for use in talking motion picture exhibitions. As shown in Fig. 1, the screen consists of a frame 5 carrying spaced bands 2, 3, in two planes, arranged to present the appearance of a continuous surface, as viewed from the front, and to leave spaces for the passage of sound d from loud speakers 4. The bands may be horizontal or vertical and may be strengthened and supported by wires stretched across the frame; they may consist of aluminium foil, and may be painted or enamelled, or pitted or stippled. The screen may alternatively consist of overlapping strips arranged like the slats of a Venetian blind, of a sheet having circular or other openings backed by spaced discs or shallow cups, or of shallow cups in staggered relation in two planes, the discs and cups being supported by wires. Fig. 8 shows a screen consisting of two layers of wire netting 20 of very fine mesh, the wires of one layer being staggered in relation to the others. The screen may be applied to the mouth of a logarithmic horn. The Specification, as open to inspection under Sect. 91 (3) (a) comprises also a screen consisting of a sheet of aluminium foil having a thickness of the order of 0.0003 inches. As shown in Fig. 11 (Cancelled), aluminium foil may be cemented to the front of a wire mesh 61, the foil being corrugated or treated to form squares or cells 60 in relief, and the sides of the squares being of the order of 1/16 inch and the depth <1>/32 inch. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to hot gas engines
IPC: F02G1/044
Filed: 1946-10-16
Abstract: 697,081. Hot gas engines. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Oct. 16, 1946 [Jan. 23, 1943], No. 30838/46. Class 7 (i). A multi-cycle closed cycle hot gas engine comprises at least two hot chambers with associated heaters and a corresponding number of cold chambers with associated coolers wherein the operative piston faces are all located in pairs such that one piston face of each pair is movable in the hot chamber of one cycle while the other face is movable in the cold chamber of a different cycle the two faces of each pair being maintained at a constant distance apart by a rigid connection between them and wherein for each cycle there are provided two piston faces of which one is movable in a hot chamber while the other is movable in a cold chamber these two movements being separated in phase to an extent suitable for obtaining power output from the engine. The word piston is defined. It does not include a displacer as disclosed in U.S.A. Specification 1,879,563 referred to. In Fig. 1 pistons 22-25 work in hot chambers and pistons 11, 12, 13, 10 work in the cold chambers 14-17. As shown the connection between each hot chamber and its corresponding cold chamber is through a heater 35 regenerator 36 and cooler 37. In order to neutralize at least partially the forces produced by the gas pressure in the working spaces one of each pair of cylinders must be closed at its lower end. Thus the undersides of the pistons 22, 23, 24 and 25 may compress during their downstroke. Fig. 2 shows a modification in which the upper part of a piston 108 acts in a hot chamber 90A which operates in conjunction with a cold chamber 92 and associated piston 95. A space 90B beneath the piston 108 comprises a cold chamber which is associated with a hot chamber in which works a piston 94 attached to the piston 95. The engine may be constructed in the shape of a V. Specifications 1872/14, 126,940, [both in Class 7 (i)], and 697,158 also are referred to.

Title: Improvements in and relating to transmitter devices for facsimile printing telegraph installations
IPC: H04L21/02
Filed: 1936-11-12
Abstract: 465,573. Fascimile printing telegraphy. SIEMENS & HALSKE AKT.-GES. Nov. 12, 1936, No. 30921. Convention date, Nov. 12, 1935. Addition to 459,275. [Class 40 (iii)] The characters are decomposed in vertical and horizontal rows of basic elemental points, like a chequer board, and impulses are transmitted corresponding to such analysis. Line distributers 20, 30, 40, 50, 60 produce trains of impulses corresponding to a scanning of the vertical rows of elemental points and are connected in desired sequence to a transmitting-line by a character distributer 70. Key contacts 11 .. 15, 37, 47, 57, 67, which correspond to the elemental points occurring in the scanning-lines of the particular character, are connected to contacts 21 .. 25, 33, 43, 53, 61 .. 65 allocated to those elemental points in the respective line distributers. All the key contacts for the character are connected to one transmitting-line, when the key 7 is depressed, and the other transmitting- line is connected through the character distributer to the rotary brushes 26, 36, 46, 56, 66 of the line distributers in turn. Impulses, corresponding to groups of elemental points which recur in a character, are transmitted by the same line distributer, Fig. 3 (not shown). For groups of elemental points which occur in different 'characters, some line distributers, upon the actuation of a single associated key contact, transmit impulses corresponding to. the entire group. All, the distributers are set in motion by the pressing of a key. Alternatively, the line distributers rotate continuously and only the character distributer is set in motion by pressing the key. A positive coupling ensures that the distributers are coupled in the correct phase.

Title: Device for effecting an antiseptic brushing operation
IPC: A46B11/08
Filed: 1947-11-25
Abstract: 655,430. Antiseptic brushes. FRITZLER, E. Nov. 25, 1947, No. 31192. Convention date, April 29. [Class 19] A device for. carrying out an antiseptic brushing operation consists of a brush, the body of which is adapted to form a reservoir for an antiseptic liquid which may be brought to a suitable temperature through an electric resistor arranged within the brush; the liquid is conveyed to its point of use through a conduit into which it penetrates under the action of a needle valve adapted to uncover the fluid inlet in the tube under the control of a lever arranged in the body of the brush. A thermostat device may also be incorporated in the supply circuit for the resistor. The liquid may have scenting, cleansing or similar characteristics in addition to antiseptic properties. Instead of using a liquid heated by an electric resistor a capsule containing a product adapted to generate a strong compression (e.g. a gas under pressure), may be used, the capsule being opened by the action of a device similar to the one used for operating the needle valve; or a product capable of producing the requisite pressure may be introduced into the liquid in tablet form. The device may also be used in connection with brooms, mops and the like. In the Figures, 1 is the body of the brush which forms a reservoir; 2 represents the bristles; 3 is an electric resistor terminating in a plug connection 4; 5 is a tube for delivering the liquid contained in 1 to the base of the brush; the communication between the tube 6 and the tank is controlled by a needle valve 7 secured to a link 8 provided with a return spring means 9 and operated in turn through a rod 10 actuated by a lever 11; the link 8 is movable around a pivot 12 and is articulated to the rod 10 by means including another pivot 13; 14 is the plug closure for the tank-filling aperture; and 15 is a thermostat device; 17 represents the handle of the brush.

Title: Improvements in the production of grain oriented electrical steels
IPC: C21D8/12
Filed: 1962-08-17
Abstract: In the production of grain-oriented electrical steel, e.g containing about 3% of silicon, hot-rolled strip is cold-rolled to an intermediate thickness, which may be twice the desired final thickness, heated to a preconditioning temperature in the range 700-900  DEG C. and then exposed to a decarburizing medium in the range 600-750  DEG C., e.g. for ten to twenty-five hours at 680  DEG C. The strip is then freed from surface oxide, cold-rolled again to final size, and then heat treated in stages to effect primary and secondary recrystallization and removal of sulphur and nitrogen. The decarburizing medium is preferably solid, such as Fe2O3, but a moist gaseous agent may be used.  Final heat treatment may consist of annealing at 700  DEG C. to effect primary recrystallization, at 950 DEG C. to effect secondary recrystallization, and finally in the range 1150-1200  DEG C. in dry hydrogen.
