Title: Improvements in motor-compressor groups
IPC: F04B39/06
Filed: 1937-07-17
Abstract: 491,997. Air compressors. GARELLI, A. July 17, 1937, No. 19845. Convention date, July 18, 1936. [Class 8 (i)] An internal - corn bustion engine 10, the compressor which it drives and a coil 3 conveying the compressed air to a reser. voir are enclosed in a common hood or casing through which cooling air is circulated by a fan 16 carried by the engine flywheel. Between the engine and the compressor a fuel tank 12 is located. The reservoir is shaped so that lubricating oil carried into it collects near the air outlet and is thus discharged at each delivery, preventing explosions. The Specification as open to inspection under Sect. 91 comprises the cooling of the coil 3 by immersion in liquid ; also a compressor delivering air to a reservoir by a coil enclosed in a jacket, through which a fan forces air, surrounding the reservoir. This subjectmatter does not appear in the Specification as accepted.

Filed: 1920-07-09
Abstract: 147,823. British Thomson - Houston Co., (Assignees of Langmuir, 1.). Dec. 29, 1913, [Convention date]. Thermionic detectors. - Relates to heterodyne reception by thermionic valves, the local source of oscillations being independent of the valve. In one method, the received oscillations are communicated to the grid 5, while oscillations of a slightly different frequency are imparted by a generator 12 to the plate 8. Beats between the two sets of oscillations are detected by means such as a telephone 9. In a modification, the telephone 9 is replaced by a resistance connected in the grid circuit of a thermionic amplifier. In another method, the aerial transformer has two primary coils, one in series with the aerial and the other in series with the local oscillation-generator through a regulating resistance, so that currents of the beat frequency are induced in the secondary coil. They are detected by means of a thermionic valve and a telephone.

Transparent laminates suitable for windshields, windows, canopies or for aircraft comprise a central flat or curved sheet 2, Fig. 2, of transparent plastics material, one, or two, surfacing sheets 3, 4, of thin glass of smaller area than sheet 2 and accurately shaped to correspond therewith, frames 7, 8 of transparent thermoset resin, and layers 5, 6, which may be of the same resin, which bond the parts 3, 4, 7, 8 to the sheet 2, and are formed by casting the resin in contact with the surfaces to be bonded. Edge layers 9, 10, resin-impregnated and bonded to sheet 2 and used for mounting the windows 2, may be formed of nylon, Orlon (Trade Mark) Glass fibre or other fabric. The frames 7, 8, and cast layers 5, 6, may be of transparent, flexible polyester, epoxy, polycarbonate, polyurethane or silicone resins containing plasticizing additives (many examples are given). The sheet 2 is preferably of stretch-oriented polymethyl methacrylate but may be of copolymers of this material with acrylonitrite, alkyl diglycol carbonate, styrene &c., or of polycarbonates, epoxy resins or P.V.C. In forming the laminated product a backing plate 11, Fig. 7, having a surface accurately shaped to that of the sheet 2, is covered by a polyester sheet 13 having channels and surface embossments permitting suction applied through tubes 17 to hold the facing sheet 3 and frame member 7 firmly in position in relation to sheet 2, similarly held by a second backing plate 28 and embossed cover sheet. Casting resin is introduced, via a pipe 27, through a sealing and spacing ring 24 to fill the space between sheet 2 and the parts 3, 7; the resin is then cured in an oven and the mould parts rearranged to surfacce the opposite face of the sheet 2. Electric heating coatings, e.g. of vapour-deposited gold covered with quartz, may be provided on the inner surfaces of the sheets 3, 4 or 7, 8.

Abstract: 390,985. Electro-therapeutical brushes. JONES, E., 32, Havelock Street, Mornington, Wellington, New Zealand. July 14, 1932, No. 19964. Convention date, Aug. 17, 1931. [Class 81 (ii).] In a tooth or body brush of the type in which the bristles are in contact with one pole of a source of electric supply, and the other pole is in contact with the user, the bristles are made of the usual non-conducting material so that the current flow only takes place when the bristles are wet and in use. As shown in Figs. 2 and 4, the handle 2 of conducting material encloses a battery 3 and is connected to one pole thereof through plug 4. The other pole 12 is connected to wires 9 which pass through the stem 8 of the head screwed into an insulating plug 6, and lie between the folds of the bristles. An indicator lamp 17, Fig. 7, may be disposed in a socket 18 which is connected to terminal 12 by wire 21 and is spring urged so as normally to hold the central plug 17a of the lamp from contacting with the other pole of the battery. Short circuiting is prevented by an insulating washer 20b provided with a central aperture. The lamp circuit is closed by pressing the lamp forward. In a further modification, Fig. 8, the handle 2 is of non-conducting material, and the head of the brush when not in use is protected by a metal cover 13, which for operation fits into the other end of the handle, and contacts with the battery through the bar 22. Contact may also be effected through a band surrounding the plug 4. In another construction, the bristles are connected to an external source of current, the operator grasping a separate conducting handle. If desired, a transformer or other device may be included in the circuit.

Abstract: 262,491. Scott, A. C. Aug. 12, 1925. Explosives.-Relates to explosive cartridges containing a charge of potassium chlorate or per. chlorate or ammonium nitrate compressed into cartridge form and then impregnated with a nitro-body such as mononitrobenzene, trinitrobenzene, mononitrotoluene, dinitrotoluene, trinitrotoluene, trinitroxylene, and picric acid.

The spreading agent may be mixed with the nitrocompound or may be brought into contact with the charge after this has been impregnated with the nitrocompound. Only an amount of spreading agent sufficient to produce the spreading action need be added, for example 1 to 4 per cent, but this amount may be exceeded. A desensitizing oil, such as castor oil, linseed oil, liquid paraffin, wool fat or lanoline, may be added; also a cooling agent such as nitrates, oxalates, and chlorides of sodium, potassium, and ammonium, but no ammonium salt should be used with a chlorate.
