Title: Improvements in, and apparatus for, testing plastic compositions
Inventor: RASCHIG KLAUS
IPC: G01N33/26
Filed: 1959-08-06
Abstract: 924,152. Testing the flow of plastic materials. F. RASCHIG G.m.b.H. Aug. 6, 1959, No. 26876/59. Class 106 (2). Heat-hardenable plastic compositions are tested for the purpose of estimating their workability by means of known Flow-Test Apparatus, including a press punch, flow channel and piston and extension arm, together with a programme transmitter and regulator whereby the course of extension of the test rod with respect to time is enforced according to a predetermined chronological programme, the variations in pressure necessary for following the prescribed course being recorded as a pressure/time diagram which serves for estimating workability. The material under test is placed in the charging space 10 of a heated press mould 11 and is forced into the flow channel 12 by a punch 9 operated by oil in a cylinder 7. Movement of the material into the channel 12 drives a piston 13 carrying a recording arm 14. The arm 14 is connected by a steel band 19, carrying a pulley 21, to a roller 22 rotated in accordance with the rate of movement required. If the pressure in the cylinder 7 is too great for the required speed, the pulley 21 rises, opening an overflow valve 29, and so reducing the pressure supplied to the cylinder 7 by the oil pump 1. The pressure in the cylinder 7 is recorded on a recording drum 17 through the medium of a pressure recorder 33. A distance/time diagram may also be recorded by pen 16 and used for controlling the regulation programme.

Title: A method of and apparatus for the indication and measurement of displacements of a point with respect to a system of co-ordinate axes
IPC: G01B7/287
Filed: 1954-09-16
Abstract: 772,190. Measuring rotary unbalance electrically. BUISSON, P. Sept. 16, 1954 [Sept. 22, 1953], No. 26903/54. Class 40 (1). Apparatus for determining the movement of a body O (Fig. 1) in space comprises three differential condensers 1, 2, 3, &e., each consisting of two fixed plates 2, 3, 2<SP>1</SP>, 3<SP>1</SP>, 2<SP>11</SP>, 3<SP>11</SP> and a central movable plate 1, 1<SP>1</SP>, 111 attached to the body O, each condenser unit having its axis located in one of three mutually perpendicular planes OX, OY, OZ, the fixed plates being supplied with an A.C. voltage, whereby the ratio of the P.D.'s between the movable plate and each of the associated fixed plates identifies the movement of the body O in each of the three planes. For determining the vibration of a rotating shaft 6 (Fig. 6), two pairs of fixed, curved plates 2<SP>1</SP>, 3<SP>1</SP>, 2<SP>11</SP>, 3<SP>11</SP> are located on perpendicular diameters of a cylinder 7 keyed to the shaft, and fixed washers 2, 3 opposite the end faces of the cylinder, to form the three mutually perpendicular differential condensers in association with the surface of the cylinder 7. The fixed plates 2<SP>1</SP>, 3<SP>1</SP> and the earthed cylinder 7 form two arms of an A.C. bridge incorporated in unit 14<SP>1</SP> together with an amplifier and rectifier to provide a D.C. voltage signal indicative of the vibration of the shaft 6 along the OY axis. Similarly, the fixed plates 2<SP>11</SP>, 3<SP>11</SP> produce a signal indicative of vibration along the OZ axis, and these signals may be fed to the plates 15<SP>1</SP>, 16<SP>1</SP> and 15<SP>11</SP>, 16<SP>11</SP> of a C.R.O. A cam, not shown, may be mounted on the shaft 6 to close a contact once per revolution to produce a bright spot on the C.R.O. trace to identify the phase position of the vibrations. To enable the axial movements to be indicated at the same time, the signal derived from plates 2<SP>1</SP>, 3<SP>1</SP> multiplied by cos α is added to the signal derived from plates 2, 3 by axial movement multiplied by sin a, before being applied to the horizontal plates 15<SP>1</SP>, 16<SP>1</SP> of the C.R.O. The multiplication is obtained by two ganged, sine-cosine potentiometers, whereby the angle α can be manually adjusted. The unbalance can be measured by duplicating the condenser units, the second set being associated with an eccentric cylinder driven at the same speed, the further condenser plates being rotatable and axially displaceable. The unbalance of the auxiliary plates can be made exactly identical with that of the shaft, and can, therefore, be located and eliminated. In another embodiment, the moving body is not a shaft but a cube 4 (Fig. 2), whose movements in three mutually perpendicular directions may be similarly determined.

Abstract: 1,195,515. Semi-conductor devices. STANDARD TELEPHONES & CABLES Ltd. 7 June, 1968, No. 27164/68. Heading H1K. The cathode region of a thyristor has a shallow centred portion 13 surrounded by a deeper portion 12, so that the gate region 2 has a central portion 5 of greater thickness than a surrounding portion 6. The Si device shown has boron or gallium-diffused gate and anode regions 2, 4 respectively and a phosphorusdiffused cathode region 1. A P+ type anode contact region is also diffused from a layer of gallium printed on to the lower surface 11 of the wafer. The outer portion 12 of the cathode region 1 is formed in two stages; viz. deposition of phosphorus from its vapour followed by a drive-in stage to produce the deep annular portion 12; while the central portion 13 is formed by a single deposition stage which results in relatively shallow diffusion. Oxide masking defines the limits of these diffusion processes. Gold is diffused into the base region 3 from a layer plated on the lower surface 11 of the wafer. Layers of nickel are plated on to the surfaces of regions 4, 1, 2 to form bases for the subsequently applied electrodes 7, 8, 9 respec tively. Individual thyristors are then divided from the wafer in which they have been formed simultaneously, and their edges are tapered by air-abrasion.

Patent GB-380954-A (GB)
Title: A process of preparing pure components or groups of components from a mixture of liquids
IPC: C10G21/28
Filed: 1931-10-03
Abstract: <PICT:0380954/III/1> A process for separating pure components or groups of components from liquids such as crude petroleum, consists in treating the oil with a selective solvent in counter current, and applying a temperature gradient to the whole or a part of the washing path. The process may be applied to the extraction of phenols with alcohol from oils containing them, or to the purification of crude petroleum or insulating oil with liquid sulphur dioxide or isopropyl alcohol.  A liquid containing components A+B is injected through an inlet o into a tower provided with heating jackets 4, 5 and cooling jackets 1, 2, 3.  The liquid rises and meets a descending stream of drops of a solvent X, the flow of which is so regulated that the solution flowing out at the top of column contains only the more soluble component A.  The solution extending below the inlet comprising X, B and decreasing amounts of A, is submitted to the temperature gradient, and at the bottom of the tower, a part of the less soluble component B separates from solution.  This fraction of B commences to flow upwards to a zone of higher temperature where it re-dissolves, throwing out component A from solution.  The solution drawn off at the base thus contains only the component B.  According to an example in which lubricating oil is treated under pressure with alcohol, a portion of the extract drawn from the top of the column (alcohol being the lighter liquid) is re-introduced in the column. Mixtures of liquids may be first separated into groups of components, and then each group separated into individual members by a selective solvent.  The formation of emulsions may be prevented by adding oleic acid or magnesium stearate or sulphonate.  Specification 355,294 is referred to.
