Title: Improvements relating to electrical pulse generators
Inventor: SCOLES GRAHAM JOHN
IPC: H03K3/55
Filed: 1963-07-25
Abstract: 1,089,903. Pulse generating circuits. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. July 14, 1964 [July 25, 1963], No. 29556/63. Heading H3P. In a pulse generator of the type in which a pulse forming network is charged, then discharged through a load to generate a pulse, the amplitude of the output pulse is regulated by a circuit controlled by a potential divider connected to an intermediate point in the charging circuit remote from the pulse forming network. As shown in Fig. 4, the pulse forming network PFN is charged via an inductor L1 and diode D1 then discharged under control of a thyratron V2 so as to generate a pulse in a load R1. When the voltage at the tapping point of resistors R2, R3 reaches a predetermined value, a trigger circuit G1 is actuated, firing a thyratron V1, so as to divert energy from the charging inductor L1 into a capacitor C1 and thus stabilize the output pulse amplitude. The energy in C1 is returned to the supply via diode D2 at the end of each pulse. A resistor R5 is provided in the charging circuit to improve the stabilization characteristic. Resistor R5 may alternatively be connected on the cathode side of diode D1. Alternatively, as shown in Fig. 11, a current transformer T may be included in the charging circuit to improve the stabilization characteristic. In Fig. 12 (not shown) transformer T is replaced by an auto transformer. The invention may be applied to the pulse generators dis-closed in Specifications 964,509, 1,053,656, 1,089,902 and 1,089,901.

Abstract: 808,749. Fluid pressure brakes. GOODYEAR TIRE & RUBBER CO. Sept. 28, 1956 [June 9, 1956], No. 29644/56. Class 103 (1). A fluid pressure operated brake, which as shown comprises a disc 29 gripped between pads 26 and 28 in a caliper support 25, is applied by pressure generated by a pump 3 and governed by a pedal-operated control valve 4, the increasing fluid pressure passed by valve 4 acting progressively upon a piston 14 in a cylinder 13 against a spring 15 until it closes contacts 16, 17. A solenoid 23 is thereupon energized so as to shut off passage of fluid through a valve 12. Simultaneously with the above operation, fluid is bled away from the actuating cylinder 8 back to the reservoir 2 through an adjustable valve 10. It is claimed that more efficient braking is carried out by such progressive and limited application of pressure. In a further embodiment, the bleeder valve is controlled electrically automatically in dependence on the temperature and heating of the brake disc as determined by a suitable thermostat.

Title: Improved method and apparatus for the purification of liquids by evaporation
IPC: B01D1/14
Filed: 1954-10-18
Abstract: <PICT:0769459/III/1> In the distillation of liquids, particularly water, the liquid is evaporated in two stages, unevaporated liquid-residues being discharged from the second stage; the vapour generated in the first stage is substantially free of entrained solids and is withdrawn from the evaporator as product, and the vapour formed in the second stage is mixed with the feed-liquid flowing to the first stage whereby the vapour condenses in the feed and preheats it.  The evaporator shown comprises a drum 12 divided into two chambers 14 and 15 by a wall 13 provided with an opening 21. A U-shaped tube bundle 22, heated by steam, is arranged in the lower part of the drum, and extends from chamber 14 into chamber 15. The top of chamber 14 is connected by conduit 33 to a preheater 17 containing a number of horizontal baffles 18.  Feedwater enters this preheater through inlet 19 and flows down over the baffles where it mixes intimately with upwardly-flowing steam from chamber 14.  The steam is totally condensed in the feedwater.  The preheated feedwater flows through conduit 16 into chamber 15. The stem generated in chamber 15 passes through separator 28, and leaves the evaporator through outlet 29.  An opening 35 in the bottom of chamber 14 provides for continuous blowdown.  A float-operated valve (not shown) is operated in response to the water-level in the preheater or the drum to adjust the flow of water through inlet 19 or blowdown 35 so as to maintain a prescribed water-level at all times in chambers 14 and 15 and the preheater.  Another embodiment is described wherein the preheater is arranged inside the drum of the evaporator.
