IPC: B65C9/12
Filed: 1921-02-24
Abstract: 159,505. Leumann, R. March 2, 1920, [Convention date]. Sheet-separators. - A machine for feeding printed or embossed sheets of tin or aluminium foil to wrapping-machines is constructed with means for separating and removing sheets of tissue paper or the like which are placed between each of the wrapping sheets. The pile of metal sheets a and paper separating sheets b are arranged in a hopper formed of adjustable sides 26 and a fixed side 24, on a table 1. The paper sheets b are separated by the action of a flat surface 3, Fig. 4, at the end of a spring-pressed lever 3, and a friction surface 13 at the end of a lever 12 fitted with an adjustable counterweight 14, and carried by an oscillating lever 8 actuated by a cam disc 6. After the members 3, 13 engage a sheet b, the lever 12 is moved by the lever 8 to cause the member 13 to approach the member 3, and the sheet is buckled as shown in Fig. 4, and by the aid of guide-plates 5 is impaled on needles 3<1> carried by the lever 3. The lever 12 is then raised from the pile by the action of a set-screw 23 on an arm 12<1> of the lever, and the lever 3 is simultaneously moved by a roller 17 on a slide 16, and it is moved in a contra-clockwise direction and the pins 3<1> are brought between slots in a stripper plate 19 which is finally moved in contra-clockwise direction by a roller 27 on the slide 16 to strip the sheet from the pins 3' and to deposit it in a receptacle. The metal sheet is then fed by a suction separator 28 and a reciprocating gripper actuated in known manner.

Abstract: 628,408. Thermionic distributers. PATELHOLD PATENTVERWERTUNGS- & ELEKTRO-HOLDING AKT.-GES. March 7, 1947, No. 6483. Convention date, March 8, 1946. [Class 40 (iii)] [Also in Group XL (c)] A cathode-ray type distributer generates an amplitude - modulated, multichannel interleaved pulse train which is passed to a transmission line through a circuit having a limited pass-band. At the end of the line, the original pulses are extracted from the complete waveform by a second cathode-ray gating device.

Abstract: 1495235 Rollers INTERNATIONAL BUSINESS MACHINES CORP 19 Feb 1976 [11 April 1975] 06493/76 Heading F2U A fuser roller 10, which in use in a xerographic apparatus is heated, forming part of a contact heat-fusing arrangement for fixing toner image material to a substrate 24, is made by applying a thin film of a silicone gum material to the surface of a rigid cylindrical member 12 and heating it in an inert atmosphere for a predetermined time at a temperature at which crosslinking occurs, thereby providing a deformable layer 16 of a silicone rubber material which serves to prevent offset transfer of toner image material from the substrate to the heat fuser roller. The member 12 may be composed of copper, nickel plated and treated with a primer for promoting adhesion of the deformable layer, or alternatively it may be composed of an aluminium alloy, treated with a chromate conversion process. The silicone gum may be a dimethyl siloxane polymer resin, which may contain a silica filler. A solution of the silicone gum in an organic solvent may be applied in multiple spray passes. After drying to dispel solvent, the roll is cured in an inert atmosphere, e.g. of dry flowing nitrogen. A curve, Fig. 2 (not shown) relating curing period and curing temperature is provided, e.g. a period of 3 hours at 600 F., for one embodiment of roll described. In use, infra-red heaters 14 may be disposed within the roll, and an opposing backup roll 18 is also provided with a surface layer 22 of a high temperature elastomer.

Title: Improvements in or relating to aviation motor fuels
IPC: C10L1/14
Filed: 1944-04-11
Abstract: An aviation motor fuel composition adapted for use in supercharged engines comprises an essentially isoparaffinic aviation base fuel containing a large proportion of alkylate gasoline, this base fuel having added thereto 2-6mls./gallon of tetraethyl lead and 2-10 per cent by volume of xylidine.  Any of the xylidines or a mixture thereof may be employed.  Base fuels which are especially desirable are those containing relatively large amounts of 2,2-dimethylbutane or 2,2,4-trimethylpentane. Alkylate gasolines from the thermal alkylation or the aluminium chloride catalysed alkylation of isobutane with ethylene or from the hydrogen fluoride catalysed alkylation of isobutane with isobutylene are suitable.  The fuel composition may contain other common fuel constituents such as gum inhibitors and agents for scavenging metallic engine deposits.  If desired, the xylidine may be omitted from the fuel composition and only injected into the fuel composition or into the engine at times of increased power demand.  In the examples, the fuel compositions consists of (a) straight run gasoline, alkylation gasoline obtained by the sulphuric acid catalysed alkylation of isobutane with butylene, mixed xylidines and tetraethyl lead and (b) straight run gasoline, isopentane, benzene, the alkylation gasoline of (a), mixed xylidines and tetraethyl lead.  For comparison purposes, fuel compositions consisting of (i) iso-octane and tetraethyl lead; (ii) composition (a) with the omission of xylidine, and (iii) composition (b) with xylidine replaced by N,N-dimethylaminobenzene or N-propylaminobenzene are described.  The Specification as open to inspection under Sect. 91 refers to a motor fuel comprising a base fuel having anti-knock characteristics together with a xylidine.  The base fuel may be straight run gasoline, thermally or catalytically cracked gasoline, polymer gasoline particularly the hydrogenated dimer from the cold acid catalysed polymerisation of isobutylene, alkylation gasoline, thermally or catalytically reformed or hydroformed gasoline and various blends of such products.  The base fuel may contain tetraethyl lead or other anti-knock agent. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in the Purification of Calcium Citrate and the Manufacture of Citric Acid.
IPC: C07C51/42
Filed: 1919-03-20
Abstract: Calcium citrate is purified by treatment with sulphur dioxide in the presence of water, the resulting solution of calcium p  bisulphite and citric acid being then boiled, after removing organic matter by filtration, to drive off the sulphur dioxide and re-form the calcium citrate.  The precipitated calcium citrate is filtered off, washed, and again subjected to the preceding treatment until sufficiently pure, when it may be decomposed with sulphuric acid to produce citric acid.  The sulphur dioxide driven off is available for the treatment of further calcium citrate. When the raw material consists of lime juice or lemon-juice, it is directly treated with calcium bisulphite, the subsequent treatment being as before.

Title: Improvements in spars or struts and longerons for use more particularly in aeroplaneconstruction, and in blades or aeroplane propellers
IPC: B64C11/24
Filed: 1923-12-10
Abstract: 220,673. Coupland, E., and Trevitt, F. J. Dec. 10, 1923. Posts and columns; screw propellers.- A longeron, strut, propeller blade, &c. is produced from a metal tube by an operation which performs an alteration of the dimension of the perimeter of the tube by spinning combined with a subsequent operation for altering the crosssectional shape of the tube. The invention is described with reference to the construction of a metal propeller blade. A tube is first reduced to the form shown in Fig. 2 by turning, rolling, or spinning, if desired the gauge of the tube being made to vary at any particular cross-section. Alternatively the parts subjected to the greatest stresses may be strengthened by placing inside the tube one or more additional thicknesses of metal. The tube is then bulged to the form shown in Fig. 3 by internal spinning. This alteration of the perimeter may also be produced by spinning down a shorter tube of the shape shown in Fig. 4, the tube being extended to the correct length by the process. The bulged tube is then given the desired cross-sectional shape by pressing it between external dies of the shape shown in Figs. 9 and 10, or by means of internal dies b, b<1>, b<2>, Fig. 11, the die b being pressed in after the insertion of the dies b<1>, b<2>. The blade is finished in suitable exterior dies, if desired, before the dies b, b<1>, b<2> are removed. The tip of the blade is closed by welding or riveting and the other end spun or staved open for securing to a boss. A two-bladed propeller may be produced from a single tube in a similar manner. Fig. 8 shows a method of securing a collar c on a blade &c.. the tube d being expanded into a groove e in the collar. Alternatively the tube d may be slightly expanded on either side of the collar.
