Abstract: 542,237. Pumps; valves. KJELLBERG. C. F. G. March 7, 1940, No. 4288. [Classes 7 (ii) and 7 (vi)] In an engine, particularly of the two-stroke type, the exhaust ports d, d<SP>1</SP> are closed by the piston on the compression stroke, and an additional charge is then supplied to the working cylinder by a pump h controlled by a rotary slide valve 3 providing the end wall 2 of the pump chamber, the wall 2 being axially displaceable so as to vary the clearance of the pump and also to act as a relief valve. Scavenging-air is supplied from the crankcase through passages c, c<SP>1</SP>, and the additional charge of mixture from the pump 1 through ports 7, 7<SP>1</SP> controlled by the valve 3, which also controls the pump inlet 6, the end wall 2 being secured to the valve 3 and adjustable axially by means of a nut 14. If ignition should occur before the engine piston g has covered the port 7<SP>1</SP>, the wall 2 and valve 3 of the pump will be forced outwardly against the action of a spring so as to increase the pump clearance and reduce the risk of damage thereto. This is further reduced, if the wall 2 is moved far enough, by the escape of excessive pressure. The pump 1 may supply a pair of cylinders.

Title: Improvements in or relating to indicators of the state of charge of an electric accumulator
IPC: G01R31/36
Filed: 1939-02-10
Abstract: 524,906. Current and voltage measurements. STANDARD - TELEPHONES & CABLES, Ltd., WARD, H. J., and DUNN, R. H. Feb. 10, 1939, No. 4433. [Class 37] [Also in Group XXXV] The state of charge of an accumulator is indicated or regulated by subtracting a constant voltage from the voltage of the accumulator and applying the remainder to a relay, which gives an alarm or effects a regulation when the voltage across it has fallen by a predetermined amount. One side of a relay R is connected to the negative terminal of the accumulator B and the other side to the moving contact of a key K. One fixed contact of this key is connected through a lamp CCL back to the negative terminal. The other fixed contact of the key K is connected over a resistance RV to the positive terminal of the battery. The lamp CCL is of the type in which the current is constant for a certain range of voltage, e.g., 0.1 ampere for voltages between 3 and 8. The key K is first operated and then restored to normal. Operation connects the relay R in series with the resistance RV across the terminals of the accumulator and causes operation of the relay to open the current of an alarm device such as a lamp AL at the contact r2. and close a circuit through the relay at the contact r1. Release of the key K then places the lamp CCL in shunt with the relay R, which is of high resistance compared with the lamp CCL. The current through the lamp CCL is constant and consequently the current through the resistance RV is approximately constant. The voltage drop across the resistance RV is therefore approximately constant and the remainder of the voltage is applied across the relay R. Any variation in voltage appears as a magnified percentage of the voltage across the relay. On a predetermined fall of voltage the relay R releases and closes the circuit of the alarm lamp AL at its contact r2. In a modification the relay R is of the voltmeter movement type having a neutral position corresponding to the normal voltage of the battery and high and low contact making positions in which the circuits are completed of relays which control the charging voltage by controlling the position of a tapping on the secondary winding of a transformer T which supplies the charging current through a rectifier DCR. In a further modification a polarized relay has two equal windings oppositely wound on the same core. The constant current lamp CCL is connected in series with one winding and an adjustable resistance in' series with the other winding. This resistance is so adjusted that at normal battery voltage the currents'in the two relay windings are equal and the armature is in - neutral position. Rise or fall of the battery voltage causes the relay to make contacts controlling the relays that control the charging voltage.

Abstract: 607,995. Moulding hollow articles from thermoplastic sheet material. BORKLAND, G. W. Feb. 13, 1946, No. 4526. [Class 87 (ii)] The heat-softened sheet s, Fig. 1, is clamped at its periphery between rings 17, 18, and a forming punch 21 having protuberances 22a, 22b, 22c and recesses 23a, 23b is lowered on to the sheet until the sheet bridges a pair of the protuberances to form a chamber between the sheet and the punch. Suction is then applied to the chamber through passages 31, 32 extending through the punch, to suck the sheet on to the punch. Descent of the punch continues to form the article, which is then allowed to harden and finally sheared off against the edge 33 by a further descent of the punch. In a modification, Fig. 5, the sheet is fed from a reel 40 through a heater 41 to a punch 21 carrying a clamping ring 57. The punch is lowered and suction applied to cup the material. The punch is then raised, suction being maintained so that the cupped sheet is lifted with the punch and the clamping ring being raised against the pressure of springs 55. The punch is then moved laterally to the dotted-line position and then lowered to shear off the cupped portion between edges 61 and 62, 63. The article may be stripped from the punch by stripping rings or plungers or by air pressure applied through passages 31. 32.
