Title: Differential pressure plastics sheet forming machine
IPC: B29C51/38
Filed: 1968-03-19
Abstract: 1,205,694. Sheet forming. BROWN MACHINE CO. OF MICHIGAN Inc. 19 March, 1968 [20 March, 1967], No. 13256/68. Heading B5A. A plunger-assisted vacuum/blow forming apparatus of the type disclosed in Specification 1,029,895 includes undercut female moulds each of which comprises radially expansible segments 54a-54d slidably carried within a recess 52 in an upper mould assembly by means of upper and lower wedge rings 53 and 54. The upper end of each segment is carried by the collar 64 of an actuating shaft 59 and is each provided with a pin 62 slidable within the slots in the arms of a spider 60 mounted upon shaft 59. The shaft 59 is actuated through a lost motion coupling by toggles (see Figs. 6 and 7, not shown) themselves actuated by the main closure mechanism and is biased upwardly, so that the segments normally assume the closed mould defining position, by a spring 78. In operation, the upper mould assembly and the segments are lowered in synchrony on to the sheet P after which the drawing operation is performed. The upper assembly is then withdrawn, the lost motion coupling in the segment actuating mechanism allowing the assembly to move up relative to the segments which thus slide free of rings 53 and 54 to a radially expansible position and project proud of the lower face of the upper assembly. Further movement of the assembly causes the segment actuating mechanism to draw the segments upwardly with the assembly thus causing them to ride over and be spread apart by the enlarged portion Z of the formed article. In this way the article is released from the mould, the segments subsequently being drawn back into the recess to their closed position in readiness for another cycle.
Patent GB-132804-A (GB)
IPC: B44C3/04
Abstract: 132,804. Wenschow, K. Feb. 14, 1918, [Convention date]. Embossing and forming.-A process of making relief maps, pictures, designs, &c. consists in placing a pattern in a frame, rendering it elastic by impregnation or otherwise, covering its back with a plastic mass while it is in an inverted position, allowing it to sag under the weight of the mass, and then embossing it with hand-tools or a matrix. The pattern a, of paper, silk, linen, &c., is clamped in a frame b, c in an inverted position, and a plastic mass d resting on the pattern causes it to sag. The relief is then produced on the pattern from below by hand-tools or by a matrix f. A cover frame c having a perforated hinged part e<1> may be placed on the frame b, c, and the whole is then inverted and the pattern is produced from above. Instead of the cover frame e, a matrix may be used to co-operate with the matrix f. After a pattern has been transformed into a relief, the plastic mass may be allowed to harden to form a matrix for the production of other matrices, between which patterns may be forced to form reliefs without the use of a plastic mass.

Title: Improvements in meters for measuring ph
IPC: G01N27/416
Filed: 1945-05-29
Abstract: 619,491. Measuring pH values. MARCONI INSTRUMENTS, Ltd., and BROCKELSBY, C. F. May 29, 1945, No. 13487. [Class 37] In a pH meter of the kind in which an E.M.F. , developed across a pair of electrodes is balanced against a potentiometer voltage, temperature compensation is given by feeding the potentiometer through a pair of resistors, one at each end, and shunting it by a further resistor, either the pair of resistors, or the further resistor or all three being adjusted automatically or by hand in accordance with the temperature of the liquid under test. The ratio of the values of the resistors of the pair determines the point on the potentiometer at which there is no change of potential in spite of the above adjustments and this point is selected to match the pH value at which the E.M.F. developed by the electrodes in use is independent of temperature changes. As shown, the potentiometer is supplied by the heater battery of a thermionic meter E, and the voltage across it is adjusted with the aid of a Weston cell tapped across a known fraction of a shunting resistor RS. Either the resistors R1, R2 through which the potentiometer is fed have -negative temperature coefficients of resistance or the resistor T has a positive temperature coefficient. Specification 468,208 is referred to.

Abstract: 514,523. Thermionic valves ; generating circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. May 9, 1938, Nos. 13739, 13740 and 13741. Convention dates, May 8, 1937, Dec. 29, 1937, and Jan 6, 1938. [Classes 39 (i) and 40 (v)] To convert direct current into pulsating current it is passed through a gas-filled discharge tube and the discharge interrupted periodically by an electromagnet. Fig. 5 shows an arrangement in which the cathode 11 of the tube 10 is heated from the source 19 on the closing of the switch S. When the tube becomes conductive current passes through it and inload 20 and heats the cathode 22 of a second tube 21. When the latter becomes conductive it allows current to pass through the coils of an electromagnet 16 which extinguishes the discharge in the tube 10. When the cathode 22 has become cool the cycle recommences. In a modification the discharge in the tube 21 is controlled by a grid, the potential of which gradually falls, owing to the heating of coresistance with a positive coefficient to the point at which it allows discharge to pass. In a further modification the potential of the grid is controlled by an oscillating circuit. In another form the electromagnet is in series with a condenser, and interrupts the current until the condenser is charged. Fig. 1 shows a valve switch for the purpose. The cathode 11 is of the indirectly-heated type and consists of two cylinders connected by radial fins 12. It is surrounded by a heat shield 14. The anode 18 is arranged opposite the end of the cathode. The valve may be filled with caesuim vapour and operate at a potential of 16 volts. U.S.A.
