Title: Apparatus for measuring and testing by supersonic vibrations
IPC: G01N29/04
Filed: 1947-10-08
Abstract: 628,170. Testing materials by supersonic vibrations. GENERAL MOTORS CORPORATION. Oct. 8, 1947, No. 27016. Convention date, April 21, 1944. [Class 118 (ii)] [Also in Group XL (c)] Apparatus for gauging members or testing materials by supersonic vibrations comprises a tunable oscillator, an electro-mechanical transducer adapted to be vibrated thereby and to be applied to the work-piece to vibrate the same and an indicator for the oscillator output current by means of which resonance in the work-piece can be indicated as the oscillator frequency is varied. The transducer, preferably a piezo-electric crystal 58, is mounted in an insulating disc 140 which is urged against a flange of an outer earthed casing 128 by a conducting spring 144 connected to a cable 54, held within a screen 126 by insulating beads 148. The screen 126 is located within the casing 128, which has three feet 130 for engagement with the work-piece 154, by a tubular insulator 150, retaining screws 152 earthing the casing. The crystal is energized by an oscillator (see Group XL (c)) manually tunable over a range of frequencies by a knob 124 and the output of which is indicated by a milliammeter 70. When the frequency is such that standing waves are set up in the test-piece, as indicated by an increase in the output current, the thickness of the test-piece may be read from a suitably calibrated dial 156 secured to the tuning knob 124. Moreover, when standing waves are set up between the crystal and any flaw or imperfect bond in the test-piece, the position of such flaw is indicated. When comparing similar test-pieces, the oscillator may be tuned to a point just off resonance for one test-piece so that slight variations in the thickness of successive test-pieces would result in large variations of the indicated oscillator output. An oil film is preferably introduced between the crystal and test-piece and the crystal is chosen so that its natural frequency does not fall within the range of frequencies used.

Abstract: 742,153. Powder metallurgy. VOGT, H. Oct. 2, 1953 [Oct. 7, 1952], No. 27035/53. Classes 83 (2) and 83 (4). [Also in Group V] Making battery plates.-Highly porous sintered metal bodies are made by allowing metal powder to settle in moulds or on webs passing through a settling chamber and then sintering. The settling-sintering process may be repeated. As shown, a strip of porous sintered metal powder is made by upwardly blowing fine metal powder by blower 4 and allowing it to settle on a travelling metallic foil or strip 6 to form a layer 7. The strip 6 is fed through the chamber 5 at a rate depending on the layer thickness required, and then through an electrically-heated sintering furnace 8 and between rollers 17, 18 to be wound on roll 9. Carbonyl iron, nickel, powdered oxide or reduced metal powder may be successively powdered on to a base or into a mould, e.g. using a succession of moulds on a heat resistant conveyer belt, and layers of different porosity may be sintered together by sintering in steps using furnaces in series. The method provides for making electrode foils, particularly for alkaline accumulators.

Patent GB-341394-A (GB)
Title: Improvements in the recovery of oil, fats and waxes from adsorptive materials
IPC: C10G1/00
Filed: 1929-09-06
Abstract: Oils, fats and waxes are separated from adsorptive silicates used in refining by treatment at a temperature between 70 DEG  C. and slightly below the decomposition point of the oils &c. with one or more solid substances, which are wetted more readily by the oils &c. than are the silicates, in the presence of water or other liquids in which the oils &c. are practically or wholly insoluble, the weight of liquid used being at least half that of the adsorption, or in the presence of inert gases or vapours such as nitrogen, carbon dioxide, steam, or vapours of formamide.  These substances may be added to the adsorptive mixture after its separation from the main body of the oil &c. being refined, or to the silicate before the refining, or at any other stage in the refining.  Amongst  the silicates used are bleaching earths, e.g. fuller's earth, and the added substances include active carbon, bran, soy bean flour, sulphur, metallic sulphides, e.g. zinc blende, or metallic oxides, or minerals containing a considerable percentage of said metal compounds, and reference is made in the Specification to methods by which the degree of capability of being wetted by the oils &c. of these materials may be determined.  When active charcoal is used, the quantity does not exceed 15 per cent of the weight of the silicate, and the other substances are usually used in amounts not exceeding 20 per cent of that weight, 10, 5 or less per cent of substances being in most cases sufficient.  The liquids used in the treatment include, besides water, aqueous solutions of ammonia or other alkaline or neutral substances, or formamide, glacial acetic acid, glycerine or other organic or inorganic liquids.  Emulsifying agents such as soaps, alkalies, sulphonic acids or sulphuric esters of organic substances of high molecular weight, and saponin may be used when liquid is employed in the treatment, generally in small amount such as 0,1-10 per cent by weight of the liquid.  In treating an oleiferous fuller's earth with active carbon in the presence of water and emulsifying agents with heating, the oil together with the carbon separates as the upper layer, while the fuller's earth freed from oil sinks to the bottom, its settlement being assisted, if desired, by the addition of neutral electrolytes such as common salt or magnesium sulphate. The oil and carbon may be separated by filtration.  Examples are given of the separation of peanut oil, olive oil, sulphur olive oil and soy bean oil from fuller's earth, and of peanut oil and soy bean oil from bleaching earth.

Title: Improvement in packing machine for powder materials
IPC: B65B1/22
Filed: 1951-11-26
Abstract: 704,203. Cartridge-filling apparatus. CANADIAN INDUSTRIES, Ltd. Nov. 26, 1951 [March 22, 1951], No. 27628/51. Classes 9(1) and 9(2) Apparatus for filling explosive into shells comprises a platform 1 supported by a metal plate removably attached to a piston 4. The empty cartridge shell 5 is placed in a holder 8 removably attached to a base pad 6 separated from the platform 1 by a layer 7 of resilient rubber. The diameter of the holder 8 may vary according to the size of shell'to be filled. The piston 4 which is guided in a sleeve 10 is attached to a connecting rod 11 driven by a crankshaft 13 housed in a crankcase 38 and rotating in bearings 14. A counterbalance flywheel 16 is connected to an extension of the crankshaft. A casing 34 encloses the driving mechanism. Rubber bellows 17 are provided to keep the explosive out of contact with the driving mechanism. Adjustable rods 19 extending through the platform 1 support a rubbercovered ring 20 in contact with a hoppersupporting bracket 23 pivoted on a hinge 24. When shells are being placed on the platform, the bracket 23 is held out of contact with the ring 20 by a holder 28 pivoted on a hinge 29 fixed to the ceiling. The mouth of the hopper 25 faces to one side and is surrounded by resilient rubber padding 31, while a rubber sleeve 32 encircles the neck of the hopper within the supporting bracket 23. Further rubber padding is placed on the underside of bracket 23, where it rests on ring 20. An electric motor connected to the crankshaft by a belt and pulley drives the shaft with a speed between 285 and 315 r.p.m. to give the piston a reciprocating motion and a stroke of 1 ¢ inches. The level to which the shell is filled is controlled by the depth to which the hopper neck enters the shell, this level being adjusted for shells of varying lengths and diameters by adjusting the rods 19. The shell moves upwards on the platform with a higher velocity than it acquires due to gravity on its downward path, with the result that its descent is arrested by the platform with a jolt which assists in tamping the powder in the shell. If the hopper 25 is replaced by a four-necked hopper, four cartridges may be filled simultaneously. A circular tension spring may be placed at the bracket hinge to prevent bouncing of the bracket. Alternatively part of the bracket may be suspended from the ceiling vertically above the hopper. The powder may be fed to the hopper by a conveyer belt system, and a battery of shakers may be provided each having a separate drive but a common feed system.
