Title: Apparatus for applying cement, plaster or other plastic composition to walls, ceilings or other surfaces
IPC: E04F21/10
Filed: 1945-04-02
Abstract: 588,643. Apparatus for spattering cement &c. MACNAB & CO., Ltd., and TOMKIN, J. W. G. April 2, 1945, No. 5201. [Class 20 (ii)] Apparatus for applying cement or other plastic composition to walls or other surfaces in a multiplicity of small blobs comprises a casing 1, a number of spring blades 8 mounted in. the casing, and a rotor 10 carrying tappets 11. The spring blades are formed by dividing a steel plate into a series of tongues like the teeth of a comb, the back edge of which is clamped between rubber or like inserts 9 in the bar 7 (Fig. 1 showing a blade in cross-section). The rotor 10 is driven by chain and sprocket from the shaft 12 mounted in rubber or like bearing bushes 13. The bushes 13 are clamped outside the casing in recesses 14. The shaft 12 is manually rotated by a crank handle. The cement or other material is introduced at 4 and settles at the bottom of the casing, so that the tappets 11 dip into it and carry it to the blades 8 which pick it up from them. Each tappet, as it engages a blade, flexes it and then suddenly releases it so that it springs forward and strikes the buffer stop 18, so projecting a blob of material through the opening 3. The stop 18 consists of a tubular rubber sheath mounted on a rod stretching across the comb. 21 is a buffer stop, of similar construction, to support the blades against the flexing action. The turned back ends of the tappets 11 assist in creating a suction effect which helps to keep heavier aggregates in suspension. It is advantageous to make the blades and tappets (or alternatively the supporting bar 7 and the rotor 10) interchangeable with others, since by suitable selection of these parts, and by regulating the consistency of the material, considerable control may be exercised over the size of the blobs projected. Although the apparatus is primarily intended for manual operation, it may be operated by flexible cable drive or by a small electric motor.

Abstract: 585,564. Propelling aircraft. BLACKBURN AIRCRAFT, Ltd., and THARRATT, A. March 2, 1945, No. 5319. [Class 4] An aircraft is provided on each side of the fuselage and rearwardly of its centre of gravity with a hinged panel 2 on the inner surface of which one or more cylinders 3 for the reception of propulsive rockets 10 are mounted, the outer surface matching the contour of the fuselage, and the arrangement being such that when the panels are swung open the rockets are positioned appropriately for firing with their axes directed to pass through or near the centre of gravity of the aircraft. The panels are operated simultaneously by hydraulically-operated mechanism, the free end of each being moved by a jack 6 connected to toggle links 7, 8. Each rocket is maintained in position in its retaining tube against a compression spring 13 by a spring catch 11, and a second catch 14 becomes operative when the spring 13 is further compressed by the thrust of the rocket. The arrangement is such that while both catches may move freely into engagement, they are withdrawn simultaneously by the plunger of a hydraulic jack 18 for the ejection of spent rocket casings. In order to prevent .closing of the panels before ejection of the spent rockets, an interlocking valve is provided in the circuit to the jack 6, the valve being actuated to prevent flow of fluid to retract the jack upon the insertion of a rocket in its tube. When in the open position the panels function to a limited extent as air brakes, and when additional drag is required the panels may be opened to function in this manner.

A shaft 26, Figs. 1 and 2, arranged centrally beneath the winding-drums 5, 6, and adapted to be rocked when desired by electric, pneumatic, or hydraulic means, carries a pair of arms 28 supporting a reel-ejecting roller 31, and a pair of arms 44 carrying rollers 45 co-operating with flat and cam surfaces 65, 43 respectively on arms 42 carried by a shaft 33 on which are mounted reel-receiving and discharging arms 32. Fig. 1 shows the position of the roller 31 and arms 32 during the winding operation. When a reel is to be discharged, the shaft 26 is turned to bring the roller 31 into engagement with the reel and move it over the drum 6. At the same time the arms 44 are lowered to raise the arms 32 into the position shown in full lines in Fig. 2 to receive the reel which rolls by gravity into contact with the arcuate ends 36 of the arms 32. Upon reversal of the shaft 26, the arms 32 are gradually lowered to discharge the reel on to the floor 25 or other receiving surface. The arms 32 may be formed with a recess 39, Fig. 1, to receive a spare winding-shaft 40. In a modification, the reel-receiving arms have straight upper surfaces to conduct the reel on to a raised receiving surface. Specification 270,254 is referred to.

Title: Electrophotographic formation of powder images
IPC: G03G9/00
Filed: 1961-03-31
Abstract: 990,538. Electrophotography. RANKXEROX Ltd. (Haloid-Xerox Inc.) March 31, 1961, No. 5663/61. Heading G2H. [Also in Division H1] A powder image is formed by applying to a conductive support, as by any of the known methods of powder image development or by use of a doctor blade of electrophoretic deposition from a liquid dispersion, a photoconductive insulating powder, uniformly charging the powder layer, exposing the charged layer to a pattern of activating radiation effecting selective discharge, removing powder selectively from the layer to form a powder image as by mechanical and/or gravitational action or by an electrostatic field, and fixing the powder image to the support, as by heat or solvent vapour. Preferably the powder particles include thermoplastic material and are less than 50 microns and the support is moved continuously or intermittently through the various treatments. Typically the powder is applied from a hopper 16 having an agitator 17 and a sieve floor 18 on to a conductive sheet 23 of paper of at least 30% humidity or a metal foil on a driven horizontal belt conveyer 20,and after charging and exposure to a light pattern, the sheet and conveyer are vibrated by a rotating triangular bar 4 to dislodge the discharged loose powder as the sheet is stripped from the belt by fingers 30, followed heating in an oven to effect fixing. A negative image may be formed by using a black paper support and a resin-coated white ZnO powder. A 3-colour cathode ray tube screen may be produced by carrying out the process successively three times using different phosphor containing powders and using an exposing light pattern of spectral composition appropriate to their spectral sensitivity, usually U.V.,and of a desired form determined by a multiple aperture grid,the tube being inverted and shaken to remove the undesired powder; or two or more powders are applied simultaneously in a chosen pattern of lines or dots or all three powders are mixed before application to the inner face of the screen, and exposure to appropriate light patterns is effected successively or simultaneously.

Abstract: 419,015. Perforated rubber sheets. INTERNATIONAL LATEX PROCESSES, Ltd., 10, Lefebvre Street, St. Peter's Port, Guernsey. Feb. 22, 1934, No. 5825. Convention date, March 24, 1933. [Class 70.] Rubber sheet or goods having minute perforations is made by spreading a latex composition on an impermeable backing having a pitted surface, in such a manner that air is retained in the pits during the spreading, and heating to coagulate the latex and cause the entrapped air to expand and perforate the rubber sheet. A textile fabric 11 coated with latex 12 in such a way as not to mask the weave forms a suitable backing, which may have from 1000 to 10,000 cavities 13 per sq. in. A fairly viscous latex mix 23, vulcanized or not, is spread on this and the whole is passed through a heater, when the latex coagulates, and the air in expanding makes perforations 22 which may be of 0À01-0À1 mm. in diameter. Several coats may be applied, with cooling between each or progressively rising temperature. The perforations then appear, under high magnification to be a series of interconnected spheroidal cavities. The sheets may be vulcanized without destroying the perforations. Unvulcanized sheets so made from latex creamed two or more times to remove serum are employed for bandages which are self adherent, but which do not stick to skin or hair. For garments, the sheets may be coated on one or both sides with textile material.
