Title: Improvements in a hair curler or waver
IPC: A45D2/14
Filed: 1924-02-14
Abstract: 218,595. West, A. A. Feb. 14, 1924. Hair-curling appliances. - A hair-curler comprises a hollow body 9, Fig. 4, and a clamping member 1, preferably of sheet metal, slidable therein and formed at one end with a hook 3 and provided at the other with a transverse pin 5. The body 9 is formed with a restricted opening at the end 12 by bending over parts of the blank from which it is formed, so that while the member 1 can slide within the body it is prevented from being completely withdrawn by, the pin 5. The hair is wound on the body with the member 1 in the position shown in Fig. 2, the member 1 is then withdrawn and turned into the position shown in Fig. 4, the hook 3 being engaged under a projection 15 on the end of the body 9. The clamping member may be formed of wire doubled upon itself.

Abstract: 986,392. Tow treating apparatus. EASTMAN KODAK CO. May 4, 1961 [May 5, 1960], No. 3948/64. Divided out of 986,391. Heading D1L. Apparatus for treating tow comprises an applicator device to apply fluid addendum to a moving tow and having a plurality of pivotally mounted hollow tubular members each having an exit orifice for the supply of addendum on to the tow, and means for imparting a reciprocating movement to the tubular members from a position in engagement with the tow to another position out of engagement with the tow. As shown tow treating apparatus comprises two metering gear pumps 56, 56<SP>1</SP> connected to tank 55, and, by flexible hoses, 50, 50<SP>1</SP> to slit tube applicators 51, 51<SP>1</SP> rigidly fastened to an arm 62 pivoted at 63. Arm 62 is connected to an air cylinder 64 (or a solenoid) so that it can be pivoted from an operative position (full lines) to an inoperative position (chain-dot lines). Applicators 51, 51<SP>1</SP> are so mounted that one slit faces generally downwards and the other generally upwards. Tow 71 passes under applicator 51 and over applicator 51<SP>1</SP> so that both sides receive an application of addendum. The slit openings of the applicators may be covered with thin felt and/or a fine mesh screen. The air cylinder 64 is co-ordinated with start-stop means of the two feed to move the applicators out of engagement with the tow when the feed is stopped and into engagement again when the feed is re-started. The apparatus is used in the formation of cigarette filters as described in Specification 986,391. Specifications 765,963, 986,393, 986,394 and 986,395 also are referred to.

Title: Improvements in or relating to adhesives
Inventor: OPIE WILFRID JOHN
IPC: C09J121/02
Filed: 1960-02-05
Abstract: An adhesive comprises an aqueous dispersion of a synthetic resin or a natural or a synthetic rubber and ungelatinized starch, the latter being present in such an amount that on heating a wet film of the adhesive above the gelatinization temperature of the starch, sufficient water is absorbed by the starch to accelerate formation of an adhesive bond and/or the drying of the adhesive. Specified synthetic resins are polymers and copolymers of styrene, vinyl acetate, vinyl propionate, vinyl chloride, acrylates and mthacrylates; and specified synthetic rubbers are butadiene/styrene copolymers, butadiene/acrylonitrile copolymers and neoprene.  The starches exemplified are potato, tapioca and maize starches; modified and partially gelatinized starches also may be used.  Optional additives are agents that lower the gelatinization temperature of the starch, e.g. urea, caustic soda, sodium acetate and zinc chloride; preservatives such as phenol and sodium phenate; and dibutyl phthalate or dibutoxy ethyl phthalate.  The adhesives may be used in bonding materials, e.g. paper to aluminium foil.

Title: Improvements in or relating to the preparation of pentaerythritol chlorideacylates
IPC: C07C31/24
Filed: 1955-02-11
Abstract: Pentaerythritol chloride acylates are prepared by reacting hydrogen chloride with a molten pentaerythritol tetraacylate or a solution of pentaerythritol in a carboxylic acid, in the presence of a Friedel-Crafts catalyst at a temperature of 120 DEG  C. to 350 DEG C.  Pentaerythritol mono-, di- and tri-chloride acetates, propionates, butyrates, valerates and caproates may be prepared from the corresponding pentaerythritol tetraacylates or from solutions of pentaerythritol in the corresponding carboxylic acids.  The catalyst may be zinc, aluminium, iron, mercuric or stannic, salts, such as chlorides, sulphates, carbonates formates, acetates or propionates. In examples, pentaerythritol trichloride monoacetate, pentaerythritol dichloride diacetate, and pentaerythritol dichloride dicaproate, are prepared by reacting hydrogen chloride with pentaerythritol in acetic acid, with pentaerythritol tetraacetate, and with pentaerythritol tetracaproate, with zinc acetate, zinc chloride and aluminium chloride as catalysts.

Abstract: 1,147,591. Feeding sheets. J. S. GUTHRIE. 21 June, 1966 [1 Feb., 1966], No. 4382/66. Heading B6B. [Also in Division G1] A plug-in source-detector unit detects presence or absence, or register of test objects, such as sheets to be printed, by reflection of light from the object. The unit comprises a two-part aluminium shell holding a bulb 6, and a photodiode 18 inclined relatively to one another. The bulb has a lens portion 10 to focus light on the test object, or alternatively a concave mirror. The bulb and detector are respectively connected to two sets of pin contacts 26, supplying power to the bulb and connecting the detector output to an amplifier, respectively. Units can be plugged into sockets at required locations in the region of the lay stops in a printing press, so as to detect the register of a sheet. Thus, three units are used to investigate the front edge of a sheet to detect whether it is twisted, has over run its register position, or is not present. The crosssection of the beam from the bulb is oval and is aligned with the edge of the sheet. A supply pulse is given to the sources and if the sheet is correctly registered a relay is triggered to actuate the printing cylinders, rollers &c. A single unit can detect the presence or absence of sheets at any stage in a particular part of the printing line.

Title: Improvements in aircraft fuel systems
IPC: F02M37/20
Filed: 1954-02-18
Abstract: 774,389. Supplying liquid fuel. SELFPRIMING PUMP & ENGINEERING CO., Ltd., MEREDEW, G. C. and MAGGS, M. R. May 18, 1955 [Feb. 18, 1954], No. 4866/54. Class 7 (3). [Also in Groups XXVI and XXIX] In aircraft fuel systems comprising two boost pumps with inlets open to the top and bottom of a fuel tank respectively, the inlet to the upper pump is closed under normal flight conditions and opened under conditions of negative g or inverted flight. As shown, a double-ended centrifugal pump mounted in a tank (not shown) comprises impellers 11, 12 carried by a vertical shaft 14 driven directly by an electric motor or turbine arranged between the impellers or through bevel gears 18, 19 from a motor &c. 20. The height of the pump unit may be varied by exchanging a shaft coupling 16 and a section 17 of the pump casing. Normally, the lower pump only is operative, fuel tapped off from the delivery by a pipe 42 flowing through a valve casing 47 to a bellows 41, or an equivalent piston or diaphragm, whereby a slotted plate 37 is turned anti-clockwise to operate butterfly valves 32 so as to close apertures 31 in a casing 30 surrounding the inlet to the upper pump which is thereby starved of fuel. A weightoperated valve 46 is then in the position shown in Fig. 4, openings 48 and 49 being in communication. Under conditions of negative g or inverted flight, the valve moves to the other end of the casing, the opening 48 is closed, and the opening 49 communicates with an opening 50 leading to the tank, whereby the supply to the bellows is cut off and the valves 32 are opened, so that the upper pump comes into operation. The valve has an axial passage 52 to avoid trapping fuel in the ends of the casing. Pressure in the upper pump when the inlet is closed is relieved by a bleed 54, Fig. 3. The outlets from the pumps are connected to the arms 26, 27 respectively of a Y-shaped conduit, the leg 28 of which is connected to the engine. A flap valve 29 is spring-biased to the position in which it closes the arm 27 and so serves as a non- return valve. The arm 26 has a suction by-pass and refuelling change-over valve as described in Specification 766,447 [Group XVII]. When the lower pump is operating normally the valve 29 is closed, but if the pressure decreases or fails it will allow the upper pump to function. The valve 46 may be movable at will to the other end of the casing when extra fuel is required under normal flight conditions, both pumps being then operative. Specification 688,349 also is referred to.
