Title: Improvements in or relating to loudspeaking telephone instruments
IPC: H04M1/62
Filed: 1959-04-30
Abstract: 909,164. Telephone sets. TELEFONAKTIEBOLAGET L.M. ERICSSON. April 30, 1959 [May 2, 1958], No. 14788/59. Class 40 (4). A loud-speaking telephone instrument includes a casing 1 housing an amplifier (not shown), a cone-type loud-speaker 2 and a microphone 3. Sound waves from the loudspeaker are emitted in a horizontal direction to avoid feedback to the microphone. The open end of the cone of the loud-speaker is directed to the bottom wall 1<SP>1</SP> of the casing 1. The microphone 3 is directed upwards. Apertures 11 and 12 are provided respectively for the loud-speaker 2 and microphone 3. The cone abuts a resonant chamber 3<SP>1</SP> divided by walls 31 and sound waves are emitted only through apertures 11. Silk or other damping material may be arranged on the inside of the casing. A disc 6 supports a dial 4 and control buttons 5 and sound insulates the microphone from the loud-speaker.

Title: Package tie
IPC: D04D9/00

Abstract: 922,422. Bonded cord fabrics. AMERICAN VISCOSE CORPORATION. April 28, 1960 [Dec. 22, 1959], No. 15010/60. Class 74 (2). A flat weftless fabric tape used, by overlapping and securing its ends, for strapping boxes, articles, &c., is formed of a plurality of high tenacity-tyre-cord type yarns adhered together in side-by-side arrangement. " Tyrecord type yarn," as herein used, means a yarn comprising two or more strands, each of which contains a multiplicity of continuous filaments, the individual strands being each twisted in the direction opposite to the twist of the complete yarn. The yarn may be of regenerated cellulose or viscose rayon, nylon, polyethylene, polypropylene, or an acrylic polymer. An adhesive may be used consisting of an aqueous solution of polyvinyl alcohol or an emulsion containing polyvinyl acetate, with or without polyvinyl alcohol, a filler, e.g. clay, and a plasticizer, e.g. dibutyl phthalate. Where the yarns are thermoplastic they may be autogenously bonded by means of heat. As shown, Fig. 6, the yarn 13 comprises two strands 14 and 15, each formed of a large multiplicity of continuous textile filaments twisted together, the strands being twisted or plied together, in the opposite direction to that of the filaments. In forming the tape a number of yarns are brought together in side-by-side relationship, led through an aqueous bath containing an adhesive, and dried under tension. In use, the ends of the tape 11, Fig. 2, are overlapped within a metal sleeve consisting of a piece of sheet metal bent into the form of a flat tube and laterally corrugated, the tape is drawn taut about the package &c. and the sleeve is then crimped entirely across the width thereof as at 18 and 19 so that each of the yarns forming the tape is correspondingly crimped. The sleeve is also deformed inwardly against the side edges of the tape at 20 to grip the tape more securely, and may be given additional small indentations on the line of the crimpings 18, 19 these indentations gripping individual yarns and being staggered in the two lines.

Title: Method and device for the production of a beam of particles
IPC: H05H6/00
Filed: 1972-04-04
Abstract: 1366199 Producing particle beams COMMISSARIAT A L'ENERGIE ATOMIQUE 4 April 1972 [9 April 1971] 15400/72 Heading G6P A beam of uncharged particles, or multiplycharged heavy ions, is produced from an incident beam of charged particles when the incident beam passes through a flowing curtain of powder material. The incident beam may comprise nuclei of hydrogen, deuterium or tritium and the powder may be chromium oxide or titanium oxide.  In the embodiment shown the powder is fed from a reservoir 10 to a supply tank 24 equipped with a stirrer, such as the rotary device 26 illustrated. From tank 24 the powder falls under gravity through a duct 34 so as to define a curtain across the path of the incident beam 36 in a charge-transfer cell 35. Depending on the charge-transfer involved between the particles of the incident beam and the powder, the emergent beam 50 will either be substantially neutral or carry a greater charge than the incident beam. Any electrons present in the latter tend to be deflected at the curtain. Coils 49 provide a magnetic field in the cell 35 which is evacuated, as is the rest of the system. Powder collected in a chamber 42 may be returned to reservoir 10 for re-use. In modifccations (not shown) the stirrer may operate on linear principles, may be electromagnetically motivated, or may comprise an acoustic generator; gravity flow of the powder may be accompaniedbyfluid-orpiston-produced impulses; the powder grains may be charged to assist flow, or accelerated by an imposed electric field; the radiation pressure of a laser beam can be used to accelerate the powder.

Title: Improvements in electric converters
IPC: H01L35/00
Filed: 1925-06-13
Abstract: 235,601. Salles, P. M. R. June 14, 1924, [Convention date]. Thermo-electric batteries.-A thermo-electric battery is so constructed that one set of junctions has a higher resistance than the other set. Alternating current is passed through the battery whereby the high resistance junctions become heated and produce a continuous current in the external circuit. The apparatus is for use particularly in wireless installations, electrolysis &c. The high resistance at the hot junctions may be produced by reducing the area of one of the elements. Fig. 1 shows the arrangement of the apparatus. The positive and negative elements are arranged in two groups A, B joined in parallel, alternating current being led in at the mid points C, D of each group and continuous current being obtained from the ends X, Y of the groups. Fig. 2 shows the construction of the couples. The elements E, F of copper sulphide and copper-nickel alloy are suspended on an insulating tube II and separated from one another by an insulating washer I. A conducting washer J connects the element F to the sulphide element of the next couple. The element F is of reduced area at G, where it makes contact with the element E. The couples are clamped together by a screwed rod passing through the tube H and carrying nuts at its ends.

Abstract: 144,720. Breisig, F. March 11, 1919, [Convention date]. Vacuum apparatus, arrangements of. - The power supplied from a source of continuous current over a long-distance conductor L is converted into alternating-current power by means of cathode tubes, whose grid electrodes are excited by alternating voltages of the frequency it is desired to use. In the arrangement shown in Fig. 1, for producing single-phase alternating current, the conductor L is connected to the anodes of a pair of tubes R1, R2 through the primary windings P1, P2 of transformers, the secondary windings S1, S2 being connected to the alternating-current load A. The cathodes of the tubes are earthed at E or connected to a return conductor, and the grids are connected to an alternating-current machine W of the desired frequency. Direct-current potentiometers may be inserted in the connexions to the grids in order to bring the average grid voltage to a predetermined value. The alternating currents produced in the tubes are so directed that their total at the branching points with the direct current conductors is always zero. A number of tubes may be arranged in series in each branch of the line LE, the grid circuits being excited from the alternator W through transformers. For polyphase working a separate tube is provided for each phase, and the grids are excited by a polyphase machine D, as shown in Fig. 3. The alternating-current generator used for exciting the grids may also be used for heating the cathode filaments. Reference has been directed by the Comptroller to Specification 102,484.
