Title: Improvements in or relating to die casting or moulding machines
IPC: B22D17/10
Filed: 1932-07-28
Abstract: 395,168. Casting synthetic resin &c. DU DONJON, N. J., 49, Boulevard Diderot, Paris. July 28, 1932, No. 21306. [Class 87 (ii).] A machine for casting or moulding synthetic resin, cellulose acetate, &c., having a mould 4 with a movable part 4a and an injection plunger 16 for forcing a charge of material into the mould is characterised in that the part 4a in its opening movement engages an abutment 16a thus forcing back the plunger 16 and returning the pressure fluid used in the injection back stroke from the cylinder 13 to a reservoir 20 through a non- return valve 19. Before striking the abutment 16a the part 4a moves along the plunger 16 to eject material between said plunger and the wall of the cylinder 22 into which the charge is inserted. The mould part 4a is moved by a fluid operated piston 6 and the plunger 16 is retained in its upper position by a friction brake 17 but can be moved down by positively opening the valve 19. When applied to a horizontal machine the charge is poured through a hole 26, Fig. 7, in a tube 27 constantly engaged by the plunger 16. The tube may be in one with the half mould 4a or may be pressed against 4 by a spring 28 so that the plunger 16 first compresses the charge which then acts on the bevelled end 30 of the tube to force it back and admit the charge to the mould.

Filed: 1947-08-06
Abstract: 633,392. Switch cases; snap-action switches. DENNIS, H. P., and DENNIS, J. P. Aug. 6, 1947, No. 21326. [Class 38 (v)] A switch of the kind described in Specification 628,074 has its mechanism interlocked with the switch-box cover B which is pivoted at T to the switch casing A and carries a catch M. A. latch lever H pivoted at S has a cranked end J bearing the word " On," and when the switch is closed, so that the toggle links C, D move to occupy the position shown to the right of the casing A, a spindle F, carried by the links, moves over a cam surface L on the lever which is lifted behind the catch M whereby opening of the cover is prevented and the word " On " is displayed through a window N. This move. ment of the spindle also moves a plate Q to the right so that its upper edge passes beneath a lip V on the lever H to maintain it raised. Movement of the links C, D and the spindle F to the left position shown, opens the switch, and the lever H drops on to a cam O on the cover. This action brings the end J clear of the catch M which displays the word " Off " through the window, and the cover can be opened. When the cover is opened, the cam 0 disengages the lever H so that it drops further and a notch K in the lever engages the spindle F to prevent closure of the switch. On re-closing the cover, the cam 0 raises the lever H to disengage the notch K from the spindle.

Title: Method of and apparatus for determinging the thickness of a layer of dielectric material during deposition
IPC: G01B7/06
Filed: 1972-05-08
Abstract: 1386306 Measuring thickness electrically PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 8 May 1972 [11 May 1971]  21358/72 Heading G1N The thickness of a thin layer of dielectric material 21 during deposition by means of cathode sputtering is determined by using an insulating plate 10 carrying conducting regions 11, 12 of which 11 is exposed to the cathode sputtering and 12 is shielded therefrom by 22. The insulating plate 10 is arranged on the metal carrier plate 15 of the cathode sputtering apparatus which carries the substrates on which the dielectric material is to be deposited. Outside of the discharge space wires 16, 17 are connected to a first voltmeter 19 and wire 16 is connected via a second voltmeter 20 to carrier plate 15 at earth reference potential. It is shown that the voltmeter readings are related to the thickness X of the dielectric layer 21 by the formula E/X = K I Vs - Vol / I VFV S | where E is the dielectric constant of the dielectric material, Vs is the potential of region 11 covered by layer 21, VF is the floating potential of region 12 determined by the discharge space of the apparatus, Vo is the carrier 15 reference potential and K is a constant dependent on various other capacitors present, Figs. 3, 4 (not shown). The detector is first calibrated by depositing a layer 21, measuring the voltages and determining the thickness X, by a known method. Further readings are taken when the layer being monitored is deposited and the unknown thickness X2 derived from the calibrated readings by dividing the two equations to give the equation X 2 =X, | Vs, -Vo|. | VF - VS 2 |/ |Vs2 - Vo|. / I V F  - V s1 .| In an alternative arrangement Figs. 5-8 (not shown) the regions 11 and 12 are on opposite sides of plate 10 so that 12 is shielded from the sputtering by the insulating plate 10.

Title: Method and means for producing moulded articles of concrete and the like materials
IPC: B28B7/46
Filed: 1957-07-05
Abstract: 851,222. Moulding concrete. INDUSTRIAL DEVELOPMENT CO., ESTABLISHMENT. July 5, 1957 [July 10, 1956], No. 21431/57. Class 87(2). The concrete, which is held under mechanical compression throughout the moulding operation, is subjected to fluid diffusion until excess water is expelled and is then treated with steam under pressure, being heated to 120-180‹, the action of the steam being maintained until the concrete has become hard. In the mould shown in Fig. 2 for the production of concrete piping, a cylindrical shell 10 has a hollow core 13 which carries a series of outwardly extending rings 16. These rings support #-shaped channel member 17 to which are secured metal sheets 18 joining one another when the mould is inoperative along lines 19. An expansible filtering or diffusing layer 20 may surround these metal sheets. Inside the shell 10 is fitted a grid 21 over the inner surface of which are fitted a number of spaced carrier sheets 22 carrying in turn on their inner surfaces a series of longitudinal strips 23. The strips form an airpermeable and expansible system of staves opening along narrow slots at the joining lines 24. Between the cylindrical systems 18 and 23 is formed the moulding chamber A for the concrete. Compressed air admitted to the core 13 at a pressure of 3-10 kg/sq. cm. acts on the channel members 17 so as to produce a mechanical pressure on the moulded mass and to open the slots at the joints 19. Compressed air is then guided through ports to the inside of the channel members 17 and thence through the slots 19 to the concrete in which it diffuses driving the excess water outwardly into the permeable area on the inside wall of shell 10. During the second or digesting stage, steam is applied under a constant or pulsating pressure of 3-10 kg/sq. cm. in the same way as the compressed air and on condensing is removed by the compressed air since the latter is held at the same pressure as the steam during the time required for the exhausting of the condensate. After, or simultaneously with, the steam treatment, reacting fluids such as vaporised sulphur, silicon tetrafluoride, and solutions of silicone elastomers and resins may be diffused through the concrete to modify its final properties.
