Title: Improvements in or relating to metal extrusion presses for the production of rod-like or tubular shaped bodies
IPC: B21C35/04
Filed: 1930-05-26
Abstract: 342,984. Squirting. KRUPP GRUSONWERK AKT.-GES., F., Buckau, Magdeburg, Germany. May 26, 1930, No. 16211. Convention date, July 1, 1929. [Class 83 (iv).] In extrusion presses the residue is stripped from the press after the operation by moving the receiver away from the matrix and clear of the residue which thereupon assumes a larger diameter and then retracting the press ram with the residue so that the latter is stripped off when the forward edge of the ram enters the bore of the receiver. A vertical extrusion press, mounted above a pit for the reception of the work, comprises a press cylinder in one with the framings 1, 3, a receiver 6 axially displaceable by pistons 7, and a ram 10, which may have a mandrel 11 adjustable by centring screws, operated by a piston 5 which is returned by an auxiliary plunger 4. After the operation the receiver is raised and the residue then stripped off by raising the ram. A cutting device 13 is then moved into position while the residue is held in a raised position by friction with the matrix 8, or by an auxiliary fork.

Abstract: 1,025,461. Automatic gramophones. H. C. HANSEN. April 25, 1962 [May 5, 1961], No. 16389/61. Heading G5R. The motor switch 80 may be opened either by clockwise rotation of a hand control 56, mounted concentrically with a speed-change control 59 or by end-of-record means 50 of well-known type. The control 56 may be turned anti-clockwise in two stages; the first starts the motor but does not engage the changer mechanism so that a single record may be placed on the turntable and the pick-up engaged manually therewith; however, at the end of play, the mechanism returns the pick-up arm and switches the motor off. Further rotation of the control 56 against resilient means also engages the mechanism to gauge a record to be played automatically, lower it to the turntable and lower the pick-up appropriately, a movement of the control 56 during play serving as a reject means in known manner; this further movement is communicated by a link 60 to the lever 50 such that the end-of-record means operates only the changer means, which in known manner, in the absence of any stored records on the centre-post at 18, opens the switch 80. The speed-change means 59, for one or more of the available speeds, may swing a lever 111 about a pivot 113 such that an abutment 115 intercepts the path of the lever 50 to prevent the control 56 from rotating sufficiently to engage the changer mechanism, so that the changer, whose speed of operation depends on the turntable speed, is prevented from operating at undesirable speeds. The remaining mechanism is as described in Specifications 759,379, 801,176, 852,061, 859,371 and 859,372, which are referred to.

Abstract: 564,194. Electric measuring systems. ZIEBOLZ, H., and GLASS, P. Nov. 20, 1942, No. 16483. Convention date, Dec. 6, 1941. [Class 40 (i)] [Also in Group XL] Electronic translating apparatus comprises a cathode-ray tube producing an electronic beam, electrons from which are caused to generate secondary energy by impact on electrons on a target, an input control circuit including a deflector for variably deflecting the beam over the surface of the electron receiving target, an output circuit including means controlled by the secondary energy generated over a definite area of said electron receiving target for establishing variable energy flow in said output circuit, and a second deflector acting on said beam and energized from the output circuit in a direction tending to deflect the beam in direction opposite to the direction of deflection by the input control circuits. Fig. 1 shows an arrangement in which the electron beam 25 of a cathode-ray tube falls on a fluorescent screen so as normally to influence equally two photoelectric cells 50, 51. Voltage from a signal source 33 acts on plates 43, 44 to deflect a beam 25 and produce a corresponding potential difference across the output circuit. Voltages from an output potentiometer 35 are fed to deflecting plates 36, 37 in a sense to oppose the deflection of the beam, and an equilibrium position is established, in which a meter 31 gives a measure of the displacement and hence of the applied signals. In a modification, Fig. 2 (not shown), the fluorescent screen and lightsensitive cells are replaced by a secondary emitting anode and the collecting anodes which feed the output circuit. In Fig. 3, the electron beam co-operates with collecting anodes containing temperature-sensitive resistances 60, 61 forming arm of a Wheatstone bridge, the out of balance voltage of which is fed to plates 36, 37 opposing deflection of the beam. In the equilibrium position the current in the load 31 is a measure of the signal applied from source 33. Specification 563,561 is referred to.

Abstract: 594,811. Subaqueous blowpipe burners. KIRKHAM, W. T. P. July 3, 1945, Nos. 16901 and 19433. [Class 75 (i)] In a subaqueous flame cutter, control mechanism is provided so that the supply of air or oxygen to the shield is automatically cutoff when cutting oxygen is supplied to the flame. A spring-pressed double-headed valve may be operated by a lever 23 which in its initial position allows oxygen to flow from a pipe 10 and bore 11 through a tube 5 to a mixing chamber, and also through a bore 18 and a tube 8 to the space 9 between the shield and the nozzle. When the lever 23 is depressed, the head 20 moves out of the bore 15 to the position shown and oxygen flows to a bore 17 and cutting oxygen pipe 7 as well as to the mixing chamber through the tube 5, but the head 21 prevents oxygen from flowing to the shield. Valve members adapted to seat upon conical seats, a rotary valve device, or two mechanically coupled valves may be used instead of the valve shown. According to the first Provisional Specification the valve may have mitre heads which abut alternately against the ends of the bore 15, or the valve may be a simple slide valve. According to the second Provisional Specification a valve housing may be provided with a feed in bore for oxygen and two valve-controlled transverse bores for a cutting oxygen line and for the mixing and shield lines. These transverse bores may be closed at one end by screw plugs and be spring urged towards gland nuts at the other end in which slide the valve stems abutting against a handle. The valve of the shield and mixing line may be longitudinally bored so that in the depressed position the valve connects the mixing and shield line with a branch passage from the cutting oxygen bore, whilst in the released position, both valves move upwards to connect the cutting line and the mixing line to the feed in bore, but to isolate the shield line. The shield line may be located above the mixing line, or a depending ported part may be provided on the valve, in which case the shield line may be below the mixing line. The two valves in the transverse bores may be side by side or in line.
