Title: Improvements in or relating to method and apparatus for casting metal
IPC: B22D13/06
Filed: 1946-09-10
Abstract: 622,240. Centrifugal casting-machines; casting processes. HARVEY, W. G. Sept. 10, 1946, No. 27142. Convention date, May 13. [Class 83 (i)] In a method of casting, in which molten metal is poured into a suspended mould which is then rotated bodily about a vertical axis until the mould is pulled by centrifugal force into a horizontal position which is maintained while the metal sets, the mould comprises a casting cavity, a pressure cavity of at least equal capacity communicating therewith, refractory material insulating both cavities from the atmosphere and a relatively small gate connecting the pressure cavity with the atmosphere at the top of the mould. A mould 2 of refractory material is formed with a casting cavity 3 and a pouring ring 4 communicating by a gate 5 with a space 6 from which additional metal is fed into the cavity 3 to make up for shrinking during cooling. Two such moulds, inserted in baskets 7 are pivotally suspended from the opposite ends of a rotatable arm 11. Molten metal is poured into the mould by gravity while the arm 11 is at rest and the arm is then rotated until the moulds swing up into a horizontal position under centrifugal force so that the metal in the cavity 3 is maintained under pressure while it cools.

Title: An improved method and installation for recovering water from atmospheric air
IPC: E03B3/28
Filed: 1934-09-22
Abstract: 432,394. Water supply. ALTENKIRCH, E., 56, Bahnhofstrasse, Neuenhagen, near Berlin. Sept. 22, 1934, No. 27307. Convention date, Sept. 28, 1933. [Class 68 (i)] Water is recovered from atmospheric air by exposing hygroscopic substances at night to the atmosphere to absorb moisture, and then in the daytime to the sun's rays while a current of air flows over the substances, the air then being cooled to deposit its moisture. The air preferably flows through absorbing and cooling zones successively in a closed circuit. The hygroscopic substances may be wood preferably cut across the grain, or leaves &c. In Figs. 1, 3 and 4, a glass-roofed room 3, which may also form a greenhouse, is connected by air outlet and inlet passages 7, 8, with a condenser 2 in the shade of a wall &c. 1. Through windows 5, thin pieces of wood 4, connected in lazytongs fashion and supported on rollers 15, may be run out on elevated rails 13 to absorb moisture during the night. At sunrise, this absorbing means is returned to the room 3 which is closed. During the day, the sun heats the air in the room which absorbs the moisture and flows in a closed circuit through passages 7, 8 and the condenser, the deposited moisture flowing to a tank 10 through a pipe 9 with an S-bend forming a liquid seal. The yield may be increased by placing finely divided wood in an upper part of the condenser in the path of the circulating air and so placed as to catch the sun only in the early part of the day. The wood &c., may be arranged on carriages for movement through the door 6 ; the windows 5 may then be double and permanently closed, or the walls may be heat insulated. A store of night air may be used for cooling and means may be provided whereby heat may be exchanged between the warm air passing to the condenser and the cool air leaving it. In a portable plant, Fig. 6, evaporating and condensing chambers 23, 24, are connected by end passages 25, 26, and are separated by a heat insulating layer 28 and an air gap 29 open at the sides of the apparatus. The evaporating chamber comprises a hinged cover, open at night and closed in the day, and a base each formed of wooden boards 30, 32, and waterproof layers 31, 33, ofasphalte paper, rubber, aluminium, &c. The walls of the passages 25, 26 also have waterproof layers 35 of aluminium &c., and the walls of the condensing chamber 24 are of similar material. The side walls are preferably protected from the sun by boards &c. The plant is placed on a slope facing the sun.

Abstract: 1,049,527. Pipe connections. GIRLING Ltd. July 8, 1963 [July 18, 1962; Aug. 9, 1962], Nos. 27557/62 and 30497/62. Heading F2G. Means for making a connection between a pipe 15 and the inlet manifold 10 of an internal combustion engine comprise a tubular coupling member 11 adapted to be inserted through a hole 13 in the manifold, a head or collar 12 carried by the coupling member at or adjacent its inner end and which abuts against the inner surface of the manifold and means engaging with the outer surface of the manifold for retaining the coupling in position. As shown in Fig. 1 the means engaging the outer surface of the manifold is an adaptor 14 which is screwed on to a spigot 17 of the coupling 11, and a resilient sealing washer 18 backed by a metal plate 19. When the adaptor is screwed home on the spigot it draws the head 12 into the wall of the manifold, which it deforms around the hole after compressing the resilient sealing washer 18. Instead of having an adaptor on to which the end of the pipe 15 fits, the coupling itself may be constructed so that it extends into the end of the pipe and the tightening may be done by a nut screwing on an external thread on the coupling. In a modification, Fig. 3 (not shown), the head or collar 26 carried by the coupling member 25 at or adjacent its inner end abuts against the outer surface of the manifold 10. The hole 28 in the manifold is entered by a short spigot 27 on the coupling member. The head 26 is tightened against the manifold, a resilient sealing washer 34 being interposed, by a clip. As shown in Fig. 3 the coupling member is fixed to one part of the clip by the engagement thereof in a groove 30 in the coupling member; alternatively, the connection may be by brazing.

Title: An improved process and apparatus for the degumming and washing of fibres
IPC: D01C1/02
Filed: 1919-11-07
Abstract: 161,219. Pritchard, R. L. Nov. 7, 1919. Washing, processes for; circulating or passing fluids through materials.-For degumming and washing fibres, uni-directional currents of suitable liquids are circulated between the fibres while they float in the liquid, the force of the current being such that the fibres are not pressed or carried towards and against each other. As shown, the fibres are placed in box-like receptacles c<1>, with perforated bottoms, placed one upon another in a cage c<2> within an open-ended false vat b resting on an open support a<1> within a vat a. The solvent liquid is pumped by a pump e from the chamber c<3> at the top of vat b into the space c between the vats a, b, the resulting difference of pressure causing the liquid to pass up through the fibres. After the fibres have been sufficiently bathed, the cage c<2> is transferred by a crane f to a false vat d<1> slidable within a vat d containing pure water. The vat d<1> is intermittently moved downwards slowly and the water that has passed through the fibres is pumped out of the vat, the fibres thus being freed from the residuum of the solvent liquid.

Title: Cathodic protection from corrosion of metal bodies in contact with electrolyte solutions
Inventor: BORDALEN KNUT
IPC: C23F13/02
Filed: 1965-06-29
Abstract: <FORM:1117525/C6-C7/1> In cathodically protecting against corrosion a metal body in contact with an electrolyte solution, at least one anode is immersed in the electrolyte, an external voltage is impressed on the or each anode and the anode current of the or each anode is regulated during the protection by varying the effective cross-sectional area of the electrolyte in proximity with the anode and through which the anode current must flow.  The variation in electrolyte cross-section for anode current may be achieved by (a) using an anode of two or more parts connected in parallel, the mutual spacing and/or orientation of which may be changed, (b) using a one piece anode which is deformable e.g. an anode in the form of bellows, helical wire or curved sheet, (c) using movable screens, e.g. automatically controlled by the potential difference between the cathode surface and a reference electrode or (d) using pneumatically or hydraulically inflatable screens e.g. in the form of a series of rubber tubes or a double walled rubber bellows.  Protection is by means of an external voltage source and the anodes may be inert or soluble, e.g. of Zn, Fe or Al.  Fig. 1 shows an anode 1 surrounded by perforated sleeves 2, 3 of electrically insulating material.  Sleeve 3 is displaced vertically by a bi-metal spring 7 when heated by a coil 8 fed by part of the anode current. Control element 9, e.g. a transistor is connected to a reference electrode and is arranged such that the current through heating coil 8 increases rapidly when the potential sensed by the reference electrode passes a value which gives protection to the cathode surface.  Increased anode current, and heating of the coil 8 cause closing of the screening system openings.  Fig. 2 (not shown) illustrates a system where the openings are closed when there is no current. Sleeves, instead of being linearly displaceable, may be rotatably displaceable.  Figs. 3 and 4 (not shown) illustrate screening by inflatable rubber tubes.
