Filed: 1942-11-19
Abstract: 571,244. Converting. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 19, 1942, No. 16365. Convention date, Nov. 27, 1941. [Class 38 (ii)] [Also in Group XXXVII] A motor 10 is supplied through grid-controlled valves 12, 13 and is accelerated in accordance with the charging of a condenser 26 through a resistor 28 to a speed preset by an adjustable potentiometer 22. Depression of start button 32 momentarily discharges capacitor 26 and, provided field relay 35 is lifted, energizes contactor 14 which locks up. When button is released, the capacitor commences to recharge and slowly changes the D.C. bias which is added to a dephased A.C. control obtained from circuit elements 19, 20, 21 and applied to the grids of the valves. The phase of the ignition of the valves is thus advanced in accordance with the difference between the voltage across the motor and across the capacitor, and the motor accelerates until the voltage there-across corresponds to the voltage at the tapping of the potentiometer 22. Depression of stop button 33 discharges the capacitor to stop the valves conducting and de-energizes the contactor 14 to place a braking resistance 36 across the motor.

Title: Electrodialysis device and method of operation
IPC: B01D61/50
Filed: 1960-05-10
Abstract: <PICT:0954021/C3/1> A method of fluid demineralization comprises increasing the linear rate of flow of the dilute stream 102 with decreasing concentration of the dilute stream in the direction of flow.  The method is applicable to the multicell apparatus described in Specification 954,022 in which the electric current density decreases in the direction of decreasing concentration of the stream 102.  All the apparatus involved are of the multicell type formed by stacks of membranes and gaskets.  Five embodiments are described. The liquid connections are for series-parallel flow through a number of substacks in the first two embodiments.  In the first embodiment, the intermembrane gaskets 451, 452 are progressively reduced in thickness in successive substacks A, B, C, thus providing smaller cell volumes in the substacks.  In the second embodiment, Fig. 1 (not shown), the number of cells in the substacks is decreased towards the outlet end of the apparatus. In the three remaining embodiments, the liquid velocity increases throughout each cell, each liquid flowing in parallel through the apparatus.  Thus, in the third embodiment, Fig. 3 (not shown), the apparatus is triangular in cross-section, the liquids being passed from the base to the apex of the triangle, whereby again the available volume decreases.  In the fourth embodiment, Fig. 4 (not shown), the apparatus is hexagonal in cross-section, the liquids being each delivered to the periphery of the cells and flowing radially inwardly to the appropriate conduit. In the fifth embodiment, Fig. 5 (not shown), each gasket is rectangular in section, but wedge shaped in side view, to provide the required decreasing volume in the direction of flow.  In all the embodiments, the cells through which the concentrate stream 103 passes are shaped the same as the dilution cells, but this is not necessary.  Two examples, employing an apparatus described above as embodiment two, are described, mentioning pressures, liquid velocities, pH values, a current of 0.55 amps and voltages of 15 and 18 respectively.  Specifications 682,703, 772,861, U.S.A. Specifications 1,972,433, 2,708,658, and Australian Specification 164,040 also are referred to.

Title: Improvements in and relating to dipping machines
Inventor: MITCHELL FREDERICK CHARLES
IPC: H01C17/06
Filed: 1954-05-10
Abstract: <PICT:0813826/III/1> <PICT:0813826/III/2> A dipping machine comprises a verticallymounted hydraulic ram, the piston of which supports a tank of coating material, means for forcing liquid into the cylinder thereof, and means for permitting the liquid to leak out of the ram at a predetermined rate, comprising an elongated duct, the dimensions of which determine the said rate for a given weight on the ram piston.  As shown in Fig. 1, a metal foil 31, to be dipped, and a plate 33 are suspended from a frame 27, on which is also mounted an hydraulic ram 28, the platform 29 of which supports a tank 30 containing coating material.  The ram is operated by a pump immersed in a storage tank 36, which supplies liquid therefrom through a stopcock 37 and non-return valve 38 to the cylinder of the ram, thereby raising the tank until the foil 31 is immersed.  The pump is then switched off and the liquid in the cylinder leaks back into the storage tank through a duct formed by a tube 39, a further non-return valve 40 and stopcock 41.  A silicone fluid is used as the hydraulic liquid to eliminate variations due to temperature and humidity changes and the platform 29 may be loaded to reduce variations in the withdrawal rate of the ram due to removal of coating-liquid from the tank 30.  An adjustable alternative device to the tube 39 comprises, as shown in Fig. 2, a cylinder 42 and a piston 43 which is a close fit therein, and is supported for axial and rotary movement by a rod 44 threaded into a socket 45 at the top of the cylinder.  A groove 46, having the same pitch as the thread on the rod 44, is cut on the outside of the piston 43, and registers with a port 47 which is connected to the ram cylinder.  The lower end of the groove 46 communicates with the space below the piston and thence with the valve 10 of Fig. 1.  The rod 44 has an operating handle 49 and its position is indicated by a pointer 53 which is coupled through bevel gears 52 to a lever 51 urged against a collar 50 on the rod 44.  The Provisional Specification also describes the process of producing printed circuits forming the subject of Specification 813,821.

Patent GB-728219-A (GB)
Title: Printed circuits
Inventor: EISLER PAUL
IPC: H05K3/38
Filed: 1951-07-16
Abstract: During the moulding of a plastic, e.g. phenolformaldehyde resin, article, there is embedded in its surface a metallic pattern constituting an electrical circuit that has been formed by etching away non-printed portions of the foil layer of a paper- or cloth-backed metal foil.  The metal foil and its support are originally united by a two-component adhesive layer (see Group VIII). One of the adhesive components may be a mould-release agent such as a silicone compound or a wax in order to facilitate stripping of the paper or cloth after moulding.  The ink resist may be removed from the metal pattern with a solvent before insertion into the mould, and the exposed metal may be etched, sandblasted, or plated to facilitate adhesion to the moulded article.  Alternatively, the ink used for the resist may contain a metal-to-plastic adhesive, or such an adhesive may be dusted as a powder over the print while the ink is wet.  The adhesives sold under the Registered Trade Marks "Araldite" and "Redux" are specified.  Methods are described for applying mould-release agents such as polyvinyl alcohol, sodium alginate, sodium silicate, or gum arabic so as to cover the paper or cloth but not the metal pattern so that the metal is firmly embedded while the paper or cloth is readily removed.
Patent GB-480644-A (GB)
Title: Improved process for obtaining coal extracts
IPC: C10G1/06
Filed: 1937-06-17
Abstract: In the process of extracting coal with solvents as described in the parent Specification wherein the solvents become partially dehydrogenated, the extraction is effected in the presence of compressed hydrogen to maintain the hydrogen content of the solvent. Hydrogenating catalysts consisting of compounds of elements of the 6th group of the Periodic system, such as molybdenum, may be present. For example, using a mixture of phenols (20 per cent) and tetrahydronaphthalene (80 per cent) as solvent, about 30 per cent of the tetrahydronaphthalene is dehydrogenated.  This is prevented by carrying out the process in the presence of hydrogen or hydrogen-containing gases under a pressure of 200 atmospheres.  Only small amounts of hydrogen are consumed, e.g. about 1 to 3 per cent relative to coal, and no volatile oils are formed.  Specification 462,478 is referred to.
