Abstract: 1,010,532. Control of two A.C. motors. TELEMECANIQUE ELECTRIQUE and ETABLISSEMENTS F. POTAIN & CIE. April 9, 1964 [April 25, 1963], No. 14715/64. Heading H2J. A hoist is driven by two induction motors MA, MB, which have wound rotors and are mechanically coupled, and means are provided for supplying one of the motors with alternating current whilst the other motor acts as a brake by supplying its stator with rectified current derived from its rotor. A rectifier D 1 -D 3 , D<SP>1</SP>1-D<SP>1</SP>3, is interposed between the rotor and stator of one or other of the motors, a second rectifier RD supplying supplementary braking-current from the mains. The motors may have different operating speeds, the slower motor MA acting as a driving unit and the motor MB acting as a brake when hoisting a load. During the lowering operation, the motors exchange their modes of operation. Either motor may drive the load alone, or the two motors may be combined to drive a heavy load. A load-responsive switch prevents highspeed operation with a heavy load. This switch also compels both motors to act as driving units when a still heavier load is being lifted.

Abstract: 792,976. Laminated sheet materials. RASMUSSEN, O. B. May 23, 1955 [June 4, 1954], No. 14740/55. Class 140. Tear-resistant sheet materials are formed by adhering together thin, uniaxially cold-stretched foils of nylon, crystalline terephthalates, polyethylene, or crystalline polyvinylidene esters with the directions of stretch in the different layers crossing. The layers are caused to adhere either by rendering them self-adhesive, e.g. by treatment with a swelling agent which is removed as by evaporating when the layers are pressed together, or by a soft elastic adhesive layer comprising polyisobutylene with tackifiers such as polyvinyl ethers. The layers may contain plasticizers. Wide stretch-oriented layers may be formed by joining together narrow bands, e.g. 1 to 10 cms. width, in edge-to-edge or overlapping parallel disposition. The bands may be formed by helically slitting longitudinally-stretched extruded tubes of the foil materials.

Title: Improvements in or relating to apparatus for measuring, recording or controlling e.m.f.
IPC: G01R1/28
Filed: 1945-06-12
Abstract: 5 9 3, 9 2 0. Thermionic voltmeters. MORTON, C. June 12, 1945, No. 14889. [Class 37] In a system for comparing an unknown E.M.F. such as that from an electrochemical cell, with the E.M.F. of a standard cell. The additional amount of overall negative feedback which has to be applied to an amplifier having a standard cell connected to its input to keep the output current constant when the unknown E.M.F. is added to that of the standard cell gives a measure of the E.M.F. As shown, the amplifier A is adjusted until meter G is undeflected when keys K and K1 are depressed, i.e. until the E.M.F. across resistor R in the output circuit equals that from Weston cell E. The E.M.F. to be measured is then connected across T5 and T6 and calibrated potentiometer R1 adjusted so that on depressing K the meter is again undeflected, when the setting of R1 is proportional to the unknown E.M.F. The bias introducing network R2, R3 is provided for balancing out so-called asymmetry potentials, which occur across the electrodes of the cell containing the solution whose pH or rH value is to be measured. The potentiometer RI is connected in a resistor network with a thermistor r2, which has a high negative temperature coefficient, and is immersed in the solution under test, in such a manner as to offset the increase in potential for a given pH value with temperature. A jack plug arrangement may be provided for cutting out this latter arrangement (or in Fig. 3, not shown) R1 and R then being connected across T3 and T4 when the arrangement may be used for measuring EH values alternatively to Fig. 2 or, may be connected to R1 and r2 shunted across either of them. To avoid shorting E an optical link may be provided in the amplifier, or alternatively the lead from b to T2 may be cut out and a second standard cell connected between T1 and K1. A.C. may be measured by first rectifying it. pH values are measured by placing a solution of known pH value in a cell connected to T5, T6 and having a suitable reference electrode, such as a calomel or silver-silver chloride electrode and an indicator electrode, bias network R2, R3 is then adjusted to eliminate that portion of the cell E.M.F. which is independent of the pH value of the electrolyte so that a potential directly proportional to the pH value of the electrolyte is applied T5, T6. For measuring rH values, a similar procedure is adopted, using a glass electrode in conjunction with a platinum or unplatinised gold electrode, the calibration solution being prepared by shaking an acid solution, e.g. potassium acid phthalate solution with solid ovinhydrone. For measuring EH values a reference electrode is substituted for the glass electrode and the cell is calibrated with a decinormal solution of hydrochloric acid saturated with ovinhydrone.
