Title: Improvements in adhesion testing machines
IPC: G01N19/04
Filed: 1957-03-01
Abstract: 813,561. Adhesion testing machines. SOUTHWICK, C. A. March 1, 1957, No. 6826/57. Class 106 (2). A machine for determining the characteristic of adhesion between a more or less porous material such as paper or cloth and coating material thereon comprises a clamp 44 holding a specimen on a support 26 over an orifice 20 of a closed chamber 18 to which air is supplied at regulated predetermined pressure for application to the specimen and a gauge 56 indicating the pressure in the chamber 18. The specimen is placed, with its coating uppermost, over the yieldable ring 26, which may be of rubber, and a lever 52 is operated to open a valve 50, so that air at, say, 50 p.s.i., determined by the setting of a pressure regulator 58 and indicated by a gauge 64, is admitted to the chamber 18 and to a cylinder 21. A piston in the cylinder 21 operates the clamp 44 to hold the specimen and air enters the chamber 18 through a nozzle with a small port taking 20 to 25 seconds for the pressure, as indicated by the gauge 56 to build up to its maximum. Air acts on the coating through the base material and any separation of the coating therefrom may be seen through an opening in the clamp. Valve 50 is closed to allow the pressure to exhaust from the chamber 18 and cylinder 21 to atmosphere so that the specimen is released for examination.

Title: Internal combustion engine installation with suction gas producer
IPC: F02B37/16
Filed: 1940-04-17
Abstract: 540,496. Supercharging. SCINTILLA, Ltd. April 17, 1940, No. 6926. Convention date, April 22, 1939. [Class 7 (ii)] [Also in Groups XXXV and XXVI] A blower 13, furnishing the suction draught to a suction gas producer 1, mixing the gas with air from a filter 17 and supplying the mixture under pressure to the suction conduit 24 of an internal combustion engine is driven by an exhaust gas turbine 31 and its speed is maintained substantially constant under varying engine output by a dynamo-electric machine 33 in permanent driving connection with the shaft 14 and geared down if necessary. A battery 36 provides power to the machine 33 at starting. When the turbine 31 takes up the drive a tachometer generator 42 energizes an electromagnet 41 sufficiently to short circuit a resistance 39 in series with the shunt field 37 of the machine 33. Continuous vibration of contacts 40 ensues whereby the machine 33 is caused to change its function progressively from a motor to a generator as the turbine 31 receives increasing power. A switch 44 is actuated when the battery voltage rises to that of a fully charged battery by a coil 46 assisted by the charging current in a coil 47. A series field 38 assisting the shunt field 37 when motoring reduces the excitation of the machine 33 when generating. A resistance 43 may be adjusted to determine the speed of the blower. The rotor of the blower has alternate ducts for air and combustible gas. In a modification a resistance in the field circuit of the machine 33 is varied by a speed-responsive governor.

Abstract: 1,200,433. Serf-regenerating plutonium concentration cells. UNITED STATES ATOMIC ENERGY COMMISSION. 10 Feb., 1969 [27 March, 1968], No. 7147/69. Heading H1B. A self-regnerating cell comprises two halfcells connected by a means for providing ion transport therebetween, each half-cell containing an electrode and a solution containing plutonium ions in nitric or hydrochloric acid wherein the acid concentration in the anolyte is up to 0À2 mole/l. and the acid concentration in the catholyte is about 1 mole/I. The equilibrium concentration of tetravalent plutonium ions is greater in the more acid catholyte than in the anolyte whilst the equilibrium concentration of trivalent plutonium ions is greater in the less acid anolyte than in the catholyte. On discharge the concentration of the two kinds of plutonium ions in the two electrolyte compartments becomes more equal. However, when the cell is standing on open circuit once more the solutions return towards their equilibrium concentrations and the cell is regenerated. The means for providing ion migration may be a salt-bridge, a liquid-liquid junction between the anolyte and catholyte or a barrier between the two containers.
