Filed: 1943-11-06
Abstract: 569,235. Aluminothermic and like processes ; alloys. LUX, E. Nov. 6, 1943, No. 18454. [Class 82 (i)] In an aluminothermic or like process for the production of alloys, the alloying metal or metals is or are added to the reacting mixture during the reaction, the addition being made gradually at moments when the equilibrium of the reaction is disturbed by local accumulation of heat or a temperature reached at which any of the components of the mixture begins to boil. Such moments are recognised by the colour of the emitted fumes with or without the assistance of spectroscopical apparatus. Compounds of the metals to be added may form part of the aluminothermic reaction mixture. Reference is made to the manufacture of alloys consisting of (1) 70 per cent copper, 30 per cent manganese; (2) 60 per cent copper, 30 per cent manganese, 10 per cent silicon. In the latter case, the silicon is added with copper filings gradually during the progress of the reaction.

Patent GB-809115-A (GB)
Title: Improvements in or relating to electric circuits employing transistors
Inventor: WOLFENDALE ERIC
IPC: H03K5/01
Filed: 1955-06-27
Abstract: 809,115. Transistor circuits. MULLARD RADIO VALVE CO. Ltd. June 27, 1956 [June 27, 1955], No. 18498/55. Class 40 (6). In a circuit-employing a junction transistor having a " punch-through " breakdown voltage Vp lying between the avalanche effect voltage Vx with zero base current and the avalanche effect voltage Bb at zero emitter current or the Zener voltage Vz (whichever is the lower), Fig. 1 (not shown), a load Rc. Fig. 4, is arranged in series with the emitter-collector path, a zero or reverse bias being applied to the baseemitter circuit. This effect may occur when the base layer is sufficiently thin, as is the case for certain high-frequency transistors, and if the curve of collector current against collector voltage is extended, Fig. 3, a negative resistance region Vw results. The voltage Vp is stated to be substantially temperature independant and is determined by base layer thickness and resistivity of the material. The capacitor C may be the self-capacitance of the transistor or an external capacitor and relaxation oscillations result. The minimum collector potential may be lowered by the effect due to storage of carriers in the base region. The circuit may be made bi-stable by employing a sufficiently low load line which intersects the vertical line Vp and a level between zero and Vx. Alternatively, by increasing the value of capacitor C sufficiently, the circuit may take up a quasistable condition with the collector potential near zero. Pulses applied at P, Fig. 7, may be regenerated with a faster rate of rise by applying them to the collector of the transistor which is operated at a potential somewhat less than that of the negative resistance region. When a negative-going pulse carries the collector potential beyond the breakdown voltage, the circuit conducts to generate an output pulse, the negative-going leading edge being due to the input pulse and the large positive pulse resulting from the triggering of the circuit. In a modification, Fig. 8, positive pulses are applied to the emitter circuit to raise the emittercollector potential above the critical value Vp, the diode D being rendered temporarily non- conducting during the period of the pulse. The base and eniitter may be connected together with a diode in the common lead. A pulse generator circuit, Fig. 9, may be triggered into operation by a positive pulse applied to the emitter causing a positive-going pulse to occur at the collector which is fed down the delay line and reflected from the far end due to the shortcircuit S as a negative-going pulse which retriggers the transistor at its collector. In a modification, the short circuit S is replaced by a terminating resistor and a connection is taken to the emitter. The circuit may include an inhibit gate so that pulse generation may be terminated, and the diode D included in the common base - emitter lead. Specification 809,116 is referred to.

[Also in Group XXIX] A hydraulic power or motion transmitting system comprises means for pumping hydraulic fluid in excess of that required to fill and actuate the system, the excess fluid passing through means designed to indicate visually that the system is operating correctly. The pumping means consists of a plunger 10 reciprocated in a cylinder 11 by a lever S2 oscillated by a cam S1 on a shaft S, such as the shaft of a ship's engine or propeller, to draw fluid in a tank 15 through a pipe 13a and inlet valve 13 and pump it through a line 16 to a piston 20 disposed in a cylinder 24 and having a rod 20a connected to a counter C to record the number of revolutions of the shafts. The fluid displaced by the plunger is in excess of that required to displace the piston and the excess fluid passes through an adjustable overspill valve 14 to a pipe 18 leading to a visual indicator 19 and the tank. The system is initially filled by slackening a plug 23 and manually or otherwise operating the plunger 10, a priming valve 12, which may be spring- loaded, being held in a closed position by finger pressure on a stem 12a during each suction stroke of the plunger until the system is filled whereupon the plug is retightened and the valve 12 secured in an open position by a gland 12b.

Title: Improvements in the manufacture of therapeutic substances
IPC: C07D277/52
Filed: 1943-11-11
Abstract: A stable compound of therapeutic value is prepared by the admixture of sulphathiazole and an amino acridine.  The reaction is preferably effected in solution.  The compound which is formed is an equi-molecular mixture of the two ingredients.  If equimolecular proportions are not used, the ingredient in excess does not interact and may be separated.  In examples: (1) 2 : 8-diamino-acridine and sulphathiazole are separately dissolved in boiling water and the solutions mixed.  An equimolecular compound separates on cooling. (2) Equimolecular proportions of the sodium salt of sulphathiazole and 5 - amino acridine hydrochloride are separately dissolved in hot water and the solutions mixed.  The equimolecular compound separates at once.  A modification of the process comprises the interaction of salts of the reactive ingredients which generate the aminoacridine and sulphathiazole respectively upon admixture.

Abstract: 1423632 Lasers PIERRES HOLDING SA 18 April 1973 [20 April 1972] 18858/73 Heading H1C To prevent radiation reflected from a workpiece from interfering with the operation of a pulsed laser in a machining system using a laser beam, the radiation incident on the workpiece is linearly polarised so that radiation reflected back towards the laser is suppressed by an analyser in the laser beam path. As shown a laser 1 comprises a ruby rod 4, resonator mirrors 2, 3 and a Brewster-angled glass plate 5 which imparts linear polarisation, the rod being pumped by pulsed energy, e.g. from a gas discharge lamp (not shown). The output radiation is passed through a polarisation analyer 7, a quarter wave plate 8 and a focusing lens 9 to a metal or jewel workpiece 10, the linear polarisation 18 being passed by the analyer and converted into circular polarisation 20 by the quarter wave plate. Upon reflection the direction of circular polarisation 22 is reversed, and the quarter wave plate converts the circular polarisation to linear polarisation 23 then suppressed by the analyer which may be a Glan-Thompson or a Wollaston prism. In a modification the Brewster-angled plate 5 is omitted and the ruby laser is internally arranged to generate a linearly polarised output.
