Title: Improvements in and relating to the production of high impulses of energy of short duration
IPC: H02K39/00
Filed: 1939-06-10
Abstract: 530,450. Supply-systems for high-frequency apparatus; indication alternators. VERTRIEBSGES. DES LEIPZIGER LEICHTMETALLWERK. June 10, 1939, Nos. 17091 and 17092. Convention dates, June 18, 1938, and Dec. 21, 1938. Addition to 432,041. [Classes 35,and 38 (iv)] In apparatus for producing pulses of current for welding or like purposes by the intermittent excitation of a generator fitted with a flywheel as described in the parent Specification, the excitation of the generator is controlled by a grid-controlled discharge-vessel. A suitable form of generator for the purpose comprises a slotted stator 1 with an axially-arranged exciting winding 12 and a slot winding 11 connected to the welding transformer 10 and an unwound toothed rotor. In the arrangment shown in Fig. 1 the winding 1 fed through mercury-vapour rectifier fitted with an auxiliary ionizing-anode 26 and starting electrode 31. The rectifier is provided with two anodes 19, 20 controlled by grids 34, 35. The grids are normally given a blocking- potential by the battery 41. To start the exciting current a switch 42 is closed raising the potential of the grid 34, and allowing the discharge to pass. When a condenser 44 in the grid circuit is charged the grid 34 resumes its former potential, but without blocking the discharge. To stop the exciting current a switch 42a is closed, giving the grid 35 a positive potential until a condenser 44a is charged. The current through the anode 20 lowers the potential of the other anode through a condenser 62 until it is insufficient to maintain a discharge against the grid 23. A resistance 12a in the circuit of a discharge through the anode 20 prevents the discharges through this anode from continuing when the grid 35 has resumed its normal potential. If alternating or three-phase current is employed the quenching anode and condenser are unnecessary and the time of the discharge is controlled by the capacity of the condenser 44 which may be variable. Fig. 4 shows an arrangement for three-phase current wherein the excitation discharge is controlled by a saw-tooth oscillation. This is provided by a transformer 56 energized from one phase of the current supply 23 and connected, along with the battery 58 to the grid 52 of a tube 51, the transformer being arranged to give a peaked voltage, which will only charge the grid in opposition to the battery 58, to a sufficient extent to allow current to pass at the peak of the voltage. The tube 51 then discharges through a variable condenser 53 and transformer 50 to charge the grid 48 of a tube 47, so as to charge a condenser 43a and stop the tube 42a by charging its grid 44a 44a through a condenser 61. At the same time the grids 34, 35, 36 of the main discharge tube are charged to allow the discharge to pass. When the condenser 43a is charged the grid 44a is de-energized and the condenser 43a discharges through the tube 42a and makes the grids 34, 35, 36 negative to stop the discharge.

Abstract: 518,214. Valve amplifying circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and KEALL, O. E. June 14, 1938, No. 17726. [Class 40 (v)] In a multi-stage amplifier in which negative feedback is used to reduce harmonic distortion due to non-rectilinear elements a phase correcting network is associated with the amplifier and a phase-shifting reactance with the feedback to ensure that the total phase shift is 180‹ Fig. 1 shows a three-stage amplifier in which a phase correcting network PR1, PC1 is associated with the grid circuit of the first stage V1. This network corrects at low frequencies and distortion at high frequencies may be corrected by network LA1, RA1, or by inserting inductance in series with the load resistance AR1 or in series with the connection to the grid of the succeeding stage. A condenser may be provided in series with the inductance LA1 and the network may include resistance and capacity in parallel. The feedback, as shown, is taken from a resistance-reactance potentiometer FBR, FBC which may include a series inductance Fig. 2 (not shown). Fig. 3 shows an amplifier having only a single network restricting its performance in which phase correction in the feedback is controlled by using the vector sum of the proportion of the voltage across the load AR1 and across the load AR2 of phase reversing valve V2. The voltage across resistance AR2 is equivalent to that obtained from a resistancenegative capacity network while its value may be controlled by using a multi-electrode variable-Á valve. Inductance may be added to or replace capacity PRC1 to effect correction at high frequencies, and where a plurality of adjustments is provided they may be gang controlled.

Patent GB-599606-A (GB)
Title: Improvements in or relating to the continuous production of hydrogen cyanide
IPC: C01C3/02
Filed: 1943-10-28
Abstract: <PICT:0599606/III/1> Hydrogen cyanide is prepared by continuously slurrying calcium cyanide with water, adding a mineral acid such as sulphuric acid to the slurry to generate hydrogen cyanide under conditions such that the interval between slurrying and acidifying is not more than four minutes at room temperature, subjecting the hydrogen cyanide to a condensing operation, and scrubbing residual hydrogen cyanide from the uncondensed vent gases with the calcium cyanide slurry.  Aqueous calcium cyanide slurry prepared in a tank 1 passes through a screen 3, filter 4 and spray heads 6 into a scrubber 7 and from thence to a vessel 9 to which sulphuric acid is added. The evolved hydrogen cyanide is freed from water by a reflux condenser 10, is condensed in a condenser 11 and is collected in a storage tank 12, the residual uncondensed hydrogen cyanide passing into the system 13.  The partially spent solution from vessel 9 is treated with steam in a steamer 15, further hydrogen cyanide being evolved, being freed from water by reflex condenser 17, being condensed in 18 and passed to storage in tank 12, the residual uncondensed hydrogen cyanide passing into system 13.  The crude hydrogen cyanide from tank 14 may be purified by distillation in a still 19, the residual gases from the still passing to the system 13. The residual gases in the system 13 are forced into the scrubber 7 by a blower 14.  If desired, the nearly spent slurry from the steamer 15 may flow into a scavenger 23 provided with beaters, a blower 25 forcing the residual hydrogen cyanide so produced through a water-condenser 26 into the scrubber 7.
