Abstract: 949,510. Transistor oscillating circuits. FIELDEN ELECTRONICS Ltd. Feb. 15, 1962 [Feb. 20, 1961], No. 6101/61. Heading H3T. In a transistor oscillator a tuned circuit 2 in the collector circuit is back-coupled to the emitter by means of two series-connected seconary windings 6, one of which gives positive and the other negative feedback. The relative amounts of feedback are varied by means of an axially movable magnetic core 5 having a critical position, at which the arrangement goes into oscillation. Oscillations are detected by a transistor detector/amplifier 11 coupled to the circuit 2 by means of winding 7 and which produces a D.C. output at its collector which depends upon whether oscillations occur and which is proportional to the movement of the core over the oscillation range.
Patent GB-434488-A (GB)
Title: Process of producing hydrogen peroxide
IPC: C25B1/30
Filed: 1934-02-24
Abstract: A continuous process of producing hydrogen peroxide consists in electrolyzing, by passing through an inter - electrode space without diaphragm, a flowing solution of a bisulphate whose specific gravity is raised beyond 1,2 by addition of sulphuric acid, so that no salt will be precipitated and the bisulphate only incompletely converted to persulphate, distilling the electrolyzed solution without addition of steam by feeding in a thin layer over a heating surface from which hydrogen peroxide will be distilled and instantly be free to pass from the heated layer for condensation, the persulphate being again converted to bisulphate forming a solution having the same content of bisulphate and sulphuric acid as the original solution, the condensed distillate being withdrawn and the residual solution after addition of the consumed water being recycled.  Suitable electrolyzing apparatus is described in Specification 430,748. The electrolyzed solution may be allowed to flow down over the external surface of internally heated piping within the distilling apparatus.  The outer walls of outer jackets of the apparatus may be heated or cooled.  The cell is fed with fresh solution at the same rate as the electrolyzed solution is discharged.  The efficiency is increased by reducing the space between anode and cathode, for instance by suspension therein of bodies of glass or other indifferent material.  The discharged peroxide and bisulphate solution may be led to collecting vessels through valves which change over automatically to switch the feed from a full to an empty vessel.  British Specification 390,549 and U.S.A. Specification 1,851,961 are referred to.

Title: Improvements in screw-thread chasing mechanism for lathes and like machine tools
IPC: B23Q1/68
Filed: 1939-02-28
Abstract: 525,751. Lathes. LUCAS, Ltd., J., and ADCOCK, H. Feb. 28, 1939, No. 6524. [Class 83 (iii)] A screwthread cutting mechanism for a lathe comprises a chasing-cutter f mounted in a tool holder e which is movable transversely of the work c and carries a nut segment h engaging a lead screw i, the tool holder being mounted on a longitudinal slide a which carries means for moving the tool holder to and from the work. The nut segment is preferably secured to a post g on the tool holder by a spring plunger j so that the nut may be disengaged if abnormal resistance is encountered. An opening n in the tool holder carries an inclined abutment shoulder o and an end member x carries another inclined shoulder w these shoulders co-acting with a vertically movable member m mounted in the slide. A spring q bearing at one end on an abutment s fixed to the slide normally urges the tool holder away from the work, the parts then being in the position shown in Fig. 4 with the nut disengaged. The lead screw which is driven from a shaft z through a clutch, not shown, is mounted in bearings y carried by a cross slide 3 on which the slide a is mounted. In operation, during rotation of the master screw, a cam 4 on the screw, depresses the member m whereby the surfaces o, p coact to move the tool holder up to the work against the spring pressure and to engage the nut segment. The depth of cut is determined by the cross slide 3. At the end of the ensuing longitudinal movement a wedge piece 6 on the slide a encounters an adjustable stop 5 and is moved against a spring 8 to shift the member m upwardly thus withdrawing the tool and the nut segment, Fig. 4. The slide a is then returned by a spring 14 or by a weight and the operation is repeated when the member m is once more depressed by the cam 4. Further depth feed may be imparted by the cross-slide 3 and when the required thread is completed the lead screw is stopped by disengaging the clutch in the drive of the shaft z.
