Title: Means for preventing or removing ice formations on the wings of airplanes
IPC: B64D15/02
Filed: 1941-12-02
Abstract: 557,905. De-icing aircraft. CLAY, W. C. Dec. 2, 1941, No. 15530. [Class 4] A de-icing device for aeroplane wings comprises a steam or other vapour generator 9 from which a closed conduit 17 extends along the interior of the leading edge of the wing, and an air heater 11 through which air is forced and caused to circulate around a partition 20 to keep the rest of the wing above freezing point. Both the steam generator and the air heater are heated by the engine exhaust gases which pass through a pipe 10, Fig. 3, in the generator 9 and through a series of tubes 13 in the air-heater before passing to the rear edge of the plane through a pipe 16. As shown, air is admitted to the heater 11 through a scoop 19 fitted with a valve 26 and finally escapes at the rear edge of the wing through a hole 25. Alternatively the heated air may be circulated in a closed circuit by an electric fan at the entrance to the heater. The higher heat content of the steam is utilized where the ice is most likely to form, and the condensed steam flows back to the generator.

Abstract: 1,107,841. High vacuum pumps. UNION CARBIDE CORPORATION. April 14, 1965 [April 24, 1964], No.15961/65. Heading FIN. A sorption type vacuum pump comprises a casing 114, 116, 118 partially filled with adsorbent material 124 for adsorbing gas in a vacuum chamber (not shown) connected to the casing by a conduit 134, the adsorbent being cooled by refrigerant fluid circulated through, or filling, tubes 120 extending through the casing and having external fins 122 in contact with the adsorbent. In the embodiment shown vessel 138 surrounds the casing and receives the refrigerant fluid filling the tubes 120. The adsorbent material 124 is retained around the tubes 120 and between the fins 122 by concentric inner and outer permeable retainers 126<a>, 126b such that gas to be pumped passes through the conduit 134, spaces 130, 132, 133 and retainers 126<a>, 126b into the adsorbent material. To re-activate the adsorbent material, warm purge gas e. g. nitrogen is passed through a tube 232 and a manifold 233 into tubes 234 from which it escapes into the adsorbent through holes disposed between the fins 122. After re-activating the adsorbent the purge gas is removed from the casing through the conduit 134. The adsorbent material may be zeolite A or X, silica gel or activated charcoal.

A heat-exchange plate for use as a heating panel or as a refrigerant evaporator has a core formed by a plurality of parallel tubes 10, of square or rectangular cross-section, adjacent tubes being joined together throughout their length and interconnected so as to form a fluid passage from a fluid inlet of the core to a fluid outlet therefrom, the core being enclosed by a gas-tight outer casing formed of plates 30, 31 conforming closely to the shape of the core and having means 33 permitting the pressure within the casing to be reduced to less than atmospheric, whereby the plates 30 are pressed by the ambient air pressure into close contact with the tubes. The core inlet and outlet connections extend to the outside of the casing as shown. The tubes may be connected in series by bevelling their ends and welding caps 22 into the triangularshaped opening thus formed (Figs. 2, 3, 4, not shown), or in parallel by fitting channel-shaped headers 32 to the pipes (Figs. 5, 6, not shown). A liquid may be introduced between the tubes and the casing. The liquid forms, a heattransmitting -film which assists the heat transfer effect of the plate.

Title: Method and apparatus for forming a conical shoulder and a fully curled neck on an end of a preformed cup
IPC: B21D28/32
Filed: 1972-04-07
Abstract: 1379129 Making cans; stamping AMERICAN CAN CO 7 April 1972 [12 April 1971] 16281/72 Headings B3A B3Q A method of forming a conical shoulder and a fully curled neck on an end of a preformed cup A comprises forming an end panel (D), Fig. 1 (not shown), into a conical shoulder B, Fig. 15, and a top flat central panel (H), Fig. 2 (not shown), integral with the shoulder, drawing the top central panel into a cylindrical throat (I), Fig. 3 (not shown), having a first height and a top flat centre panel (J) integral therewith, removing a centrally-located circular portion K, Fig. 12, of the centre panel to leave an annular rim (L), Fig. 4 (not shown), integral with the throat, drawing the throat and rim into an open-ended cylindrical throat I<SP>1</SP> having a height greater than the first height, and forming a fully curled neck C on the conical shoulder B. The preformed cup is fed, e.g. by a rotary, multi-pocketed turret (not shown), and positioned between die assemblies 14, 16 at station 10, Fig. 7 (not shown). Reforming die 18, throat drawing die 20 and piercing punch 24 are slidable relative to each other. Also, cut-edge die 30 is slidable relative to reforming die 28. Thus, sequential operation may be performed whereby die assemblies 14, 16 are moved, e.g. by hydraulic pressure, towards each other, Figs. 8-11 (not shown). Alternatively, one assembly may remain stationary. The application of pressure to assembly 16 when contacting assembly 14 causes drawing die 20 to move relative to reforming die 18 to form the throat I. Further pressure causes movement of piercing punch 24 which, in co-operation with cutting edge 38 removes the centrally-located circular portion K. Then the cut-edge die 30 is displaced away from die 20 which forms an openended throat I<SP>1</SP>; simultaneously the portion K is ejected from bore 34. The cup A is then removed from the retracted die assemblies and transferred to station 12, Fig. 13 (not shown), to be clamped between mandrel 40 and curling assembly 42. A locating pin 60 is inserted into recess (58), Figs. 13, 14 (not shown), to align the mandrel and assembly, and top (M) of the throat I<SP>1</SP> is moved into contact with curling groove surface 56. Continuous forward movement of mandrel 40 causes contact between throat I<SP>1</SP> and groove surface (56) and thence a curled neck C. The cup is then stripped from the second station. In the two-stage operation, die 18 moves towards die 28, and mandrel 40 moves towards assembly 42. However, alternatively die 28 may be moved towards die 18, and assembly 42 towards mandrel 40.

A method for use in the production of a copy of an original text to be copied comprises the steps of placing a transfer sheet having on one side thereof a transferable layer containing an ink or dye, and having directly or indirectly on the first said layer a further layer, of latently adhesive material of such nature as to become effectively adhesive when heated to a temperature above normal room temperature but below its melting temperature and below the melting temperature of the first said layer, with its layered side in contact with a further sheet, on which the copy is to be made, subjecting both layers to a differential infra-red irradiation by direct illumination through, or reflex illumination from, the original text, allowing or causing the sheets and layers to cool to below the adhesion temperature of said adhesive material and separating both sheets, portions of the further layer and the corresponding formerly underlying portions of the first said layer, which portions correspond to the original text, being removed from the transfer sheet on said separation, as a result of the adhesion of the said portions of the further layer to the further sheet. The latently adhesive layer may comprise a thermoplastic synthetic resin. The latently adhesive layer may be, for example, an isobutylene polymer, butyl rubber, abietyl alcohol or an ester of abietic acid. The transferable layer may comprise a triphenylmethane dye embedded in fat and wax. Three examples are also given of compositions for transfer layers comprising crystal violet, Victoria blue and lamp black with milori blue respectively in various wax and fat compositions. All but the last example are of use in the production of printing master sheets. If an intermediate layer is present between the transferable and latently adhesive layers it should be substantially non infra-red absorbing and may comprise for example equal amounts by weight of hard paraffin and bentonite. The original text may either be on a separate sheet or printed on the back of the sheet on which the copy is to be made.

The leading end of the shank 24 is of reduced cross-section to facilitate insertion in the aperture 36. As the maximumwidth portion of the shank 24 is pushed through the aperture 36 (Fig. 2) the leading end of the shank is deformed forwardly. Abutments 40, 42 on the inner faces of shank elements 26, 28 engage abutments 44, 46 on the web 38 to limit transverse compression of the shank.
