Title: Improvements in self-closing valves for controlling the flow of fluids
IPC: F16K17/00
Filed: 1941-12-06
Abstract: 549,279. Self-closing valves. HOPKINSONS, Ltd., and DALE, W. B. Dec. 6, 1941, No. 15767. [Class 135] A self-closing valve automatically closing on failure or cessation of supply and re-opened by a manual operation particularly adapted for controlling the supply of compressed air to mine machinery comprises a main valve member a opening in the direction of flow and actuated by a leaky piston f controlled by a spring loaded auxiliary valve h actuated by a diaphragm j. To open the main valve a quadrant o is actuated by a detachable handle p to hold the valve h closed so that pressure leaking past the piston balances the pressures on the piston so allowing the inlet pressure acting on the valve member to move it to the open position. Outlet pressure passing through the passage m to the chamber k acts on the diaphragm to hold the valve h closed. Should the outlet pressure fall abnormally the spring j<SP>1</SP> opens the valve h and connects the chamber above the piston to atmosphere through a passage i so allowing pressure below the piston to close the main valve. To test the device the quadrant is operated to close a valve n in the passage m and open a slide valve r to connect the chamber k to atmosphere. The handle p has a socket adapted to engage a squared end on the spindle of the valve q when a projection on the socket is passed through a recess in a guard member.

Patent GB-1217522-A (GB)
Title: Semiconductor oscillator
IPC: H01L47/00
Filed: 1968-04-04
Abstract: 1,217,522. Semi-conductor oscillators. INTERNATIONAL BUSINESS MACHINES CORP. 4 April, 1968 [14 Aug., 1967], No. 16232/68. Heading H3T. [Also in Division H1] An oscillator uses a body of a semiconductor material which at least in certain crystallographic directions has the drift velocity applied field relationship shown. In the embodiment the body is of germanium doped with antimony or bismuth and is provided with two non- injecting contacts such that the field is applied in a (100) direction. The contacts are of soldered or alloy type and include diffused or alloyed terminal regions of the same conductivity type as the centre of the body. To obtain oscillations the voltage applied to the two contacts must exceed a threshold voltage v 1 ; above this threshold oscillations categorized as Type I occur until a voltage v 2  is reached when they cease. Type II oscillations occur in a higher voltage range v 3  upwards, the upper limit of this range being made less than the voltage which produces avalanche breakdown of the body. For many devices v 2  = V 3 . Within the lower part of the range v 1 -v 2  the frequency increases slightly with voltage; at a certain point it jumps by a factor of about 2 and then again, in the upper part of the range, increases slightly with voltage. With some of the devices the v 1 -v 2  range is split into three parts: high v; low v; high v. The Type IT oscillations, which occur at roughly a tenth of the frequency of the Type I oscillations, are believed to arise from a minority carrier mechanism involving periodic local avalanching (resulting from impact ionization) but not total breakdown. Type II operation is favoured by using lower temperatures. At very low temperatures and at voltage above v 1  a crystal length-dependent Type III oscillation may occur which involves a domain propagation mode which, like the other modes, is not, however, thought to involve an inter-valley transfer mechanism. The preferred geometry for Type I operation is described by Fig. 11A (not shown) and that for Type II operation by Fig. 11B (not shown). The shape of Fig. 11C (not shown) allows Type I oscillation to take place at a lower v 1  than for an otherwise similar uniform body but leads to a lower amplitude of oscillation and polarity dependant operation. The oscillators may have resistive or reactive loads; the latter may be tuned and though shown in Fig. 1A as comprising discrete components may instead be a cavity or waveguide completely or partially containing the semiconductor device to which it is electromagnetically coupled. Tests show that the oscillations are pressure-dependant, through this fact is not made use of in operation of the embodiments.
