Abstract: 975,545. Refuse-consuming furnaces. METALLBAU SEMLER G.m.b.H. Oct. 26,1962 [June 8, 1962], No. 40570/62. Heading F4B. Apparatus for burning solids, e.g. garbage, comprises a rotary frusto-conical drum 16, Fig. 2, formed with perforated walls and disposed in a furnace 6 with the axis of rotation 17 inclined upwardly towards the open bore of the drum so that the lowermost surface line 16<SP>1</SP> is either horizontal or downwardly inclined away from the axis, a charge shoot 37 feeding the drum through said open base, and an air supply pipe 19 feeding a tuyere 19<SP>1</SP> shaped to the contour of the drum and encouraging the establishment of a combustion zone slightly offset from line 16<SP>1</SP> and into which rotation of the drum continuously tumbles the burning solids. Combustion gases leave the furnace by a flue 12 formed with a constriction 12<SP>1</SP> and a tangential air inlet 40 to encourage deposition of solid particles &c. are then divided into two streams. One stream is diverted by a fan 14 and pipe 13 to a feed hopper 4, where it mixes with air entering at 5 to preheat incoming material, a fan 9 then drawing off the mixed gases, diluting them with further air supplied through pipe 10 and supplying the resultant mixed gases to the pipe 19. The other stream is drawn by fan 46 through washing towers 41 and 44 and fed to chimney 47, drawing in air and discharging the mixture through a restricted outlet 50. Ignition is by a burner disposed near the tuyere 19<SP>1</SP> and small ash falls through the perforations 18 in the drum into ash-pan 25 which may be withdrawn through closable opening 38. Large particles are periodically discharged into said ash-pan by tilting the drum about axis 21 and opening hinged flap 24. The drum is rotated at 20-40 r.p.m. by a motor-driven gear having pins engaging a pin ring 26 held by rollers 32, 34 mounted on a frame 30. The perforations 18 have a diameter of 10-20 mm., being arranged at a spacing of 5-10 mm., and the cone angle for the drum is 90-120 degrees.

In Fig. 2 the device is shown mounted on a table 16. Film 17 of e.g. polyethylene is led from a reel 18 so that it passes under and over a folding bar 19 so as to form upper and lower plies 17a, 17b. When it is desired to package matter or an article the latter is placed between the upper and lower plies and in advance of the heating bar 1 (the leading edge of the two plies having been sealed in the previous operation) and the heating bar 1 is lowered to seal and sever the plies around the article 24. In other embodiments the sealing and severing device is of J or U formation. Specification 973,109 also is referred to.

Abstract: 1,155,443. Photo-electric flow measurement. BECKMAN INSTRUMENTS Inc. Sept. 12, 1967 [Oct.27, 1966], No.41670/67. Heading G1A. [Also in Division G3] In a system for maintaining a constant flow of gas through a conduit, the pressure differential across a capillary inserted in the conduit is measured by a liquid manometer having a reflecting light-sensitive pick-off controlling a pump conveying gas through the conduit. In Fig. 1, a flow of gas, e.g. for analysis, is produced by a pump 26 through a capillary 20. Variations in the rate of flow are detected by changes of the level of oil 28 in a manometer 10. Such changes vary the amount of light transmitted from a lamp-36 and reflected from the inclined end of a light conducting rod 32 through a slit 40 on to a photo-cell 42. Photo-cell controls through line 46 the A. C. energization of a coil arranged in a resonant circuit (not shown) to vary the output of pump 26 and thereby maintain the flow of gas constant. The rate of flow is indicated by the level of oil against markings 46 on transparent leg 14. Use of a manometer having concentric legs is referred to.

Abstract: 1,123,590. Read-only stores. INTERNATIONAL STANDARD ELECTRIC CORP. 23 Sept., 1966, No. 42492/66. Heading G4A. [Also in Division G1] A method for producing a satisfactory matrix of integrated circuit components such as diodes. transistors, capacitors or resistors for use in e.g. a read only store consists in making a first matrix at least as large as that required, testing the individual components and producing a record showing those which are faulty, which record is stored, e.g. photographically. A stored record of the required matrix pattern is compared with a pattern selected from the record of the first matrix, and if a sound component occurs at every required intersection, a signal indieating a satisfactory matrix is provided. If such a signal is not produced a comparison is made with other selected patterns until a satisfactory pattern (if any) is found. Suitable conductors are applied and connected to the output terminals, and components not required are burned out. The first matrix may either be larger than the required matrix, particular rows and columns being selected for the comparison with the required pattern or it may be the same size, rows and/or columns being interchanged to produce the various patterns for trial in the comparison step. In this latter method a second matrix is required for connecting the first matrix to the output terminals.

The coating may contain one or more waxes, petroleum jelly, polymeric materials, and animal, mineral, or vegetable oils. The support may be made of plastics film, e.g. a polyester film or paper. In the latter event, a barrier coating, e.g. of ethyl cellulose or a copolymer of vinyl chloride and vinyl aceteate may be applied prior to coating with the lencauramine derivative-containing composition. In use, the coated surface of the carbon paper is placed in contact with a surface of a master copy sheet and the other surface of the master copy sheet is typed on such that a substantially colourless reverse image is produced on the first-mentioned surface of the master copy sheet. This surface is then brought into contact successively with a plurality of sheets of copy paper moistened with a copying fluid in the presence of an acidic substance so as to produce a visible reproduction of, the typing on each of the copy sheets. The copying fluid may be methylated spirits optionally together with benzyl alcohol. The acidic substance may be present in the copying fluid or on the copy paper. In the former case, it may be an inorganic or organic acid, and in the latter case it may be an acid mineral or an acid-treated coating.

In a steam generator, particularly for nuclear reactors, condensate is re-evaporated by passing superheated steam through it. In Fig. 2 the main superheated steam pipe 7 passing axially through the tank 6 has branch pipes 10 extending across the generated steam outlet 19 through the steam space and into the preheated condensate, the steam being emitted from the annular member 12. These branch pipes 10 may be grouped into conduit tubes 11 as shown. Shields 13 and 14 direct the feedwater from inlet 15 around the periphery of the tank 6 and through the annular space between them into the vicinity of the member 12. The generated steam is deflected by the frusto-conical extension of shield 14 to pass through outlet 17 over the branch pipes before leaving the tank. The tank may be spherical, or cylindrical with hemispherical caps. The branch pipes may be spirally or similarly arranged and are connected to the main pipe through control means such as valves. The flow of feedwater into the tank is controlled, and a pipe 18 connects the condensate into a servo-cycle, e.g. to cool the condensate after shutting down.
