Title: Hydraulic press
Inventor: WALKER ARTHUR RAYMOND
IPC: B30B15/16
Filed: 1964-02-27
Abstract: 1,094,132. Extrusion presses. LOEWY ENGINEERING CO. Ltd. Feb. 23, 1965 [Feb. 27, 1964], No. 8115/64. Heading B3P. [Also in Division B5] An hydraulic press, suitable for backwardly extruding workpieces, includes platens 2 and 4 which are connected by a framework 6 and between which move independent crossheads 32 and 38. To the crosshead 32 are attached piston rods 28 and the main ram 18 of a removable tool 20. The piston rods move in fixed cylinders 22 and in cylinders 30 on the crosshead 38, bores 27 in the piston rods hydraulically interconnecting the cylinders. A workpiece B is mounted within dies 14 and 8 on the platen 2 and is adjustable horizontally and vertically by fluid pressure cylinder assemblies 56 and 58. In operation, fluid is introduced by a valve 66 to both the upper sides of pistons 24 to depress simultaneously the pistons, due to their differential area, the crossheads 32 and 38, and the tool 20. When a ring 40 co-operates with the fixed surface 43 of the die 8, the crosshead 38 halts and the crosshead 32 and tool increase in speed downwardly due to the bores 27 connecting the cylinders 22 and 30. A micro switch then opens valve 70 to introduce pressure fluid above ram 18, to commence extrusion. The space above the ram was previously filled with low pressure fluid from a reservoir 60. On completion of the operation the cylinders 16 and 22 are vented by valves 72 and 68, the residual pressure fluid in the cylinders 22 below the pistons 24 causing the crosshead 32 to rise to its original position. A stripper ring 42 prevents the extruded workpieee from sticking to the tool. The crosshead 38 is returned to its original position, and the workpiece is removed to allow the operation to be repeated.

Title: Improvements in and relating to Aseptic Packaging of a Sterile Liquid
IPC: B65D5/06
Filed: 1968-02-20
Abstract: 1,183,149. Packaging sterile liquids; filling bottles; cartons. TETRA PAK A.B. 20 Feb., 1968 [6 March, 1967], No. 8272/68. Headings B8C, B8P and B8T. A flexible container is sterilized by an agent which enters the container through a pipe engaging the container opening of the container then being filled with sterile liquid through the same pipe and the opposite sides of the container's neck are sealed together, prior to disengagement of the pipe. Two coaxial pipes may be used, the inner of which feeds in the sterilizing medium and then the contents and the outer makes sealing contact with the container mouth. In the embodiments shown, telescoping coaxial pipes 3, 4 are used, the inner of which descends to the base of the container and rises as the container fills. The outer pipe 4 of one arrangement, engages the mouth 13 of a container 1 e.g. a plastics bottle, a gaseous or liquid sterilizing agent entering the bottle through the . lowered inner pipe 3, Fig. 1b, and leaving through the outer tube 4. For gaseous agents, the bottle may be upside down. Sterilized liquid is then introduced and when filling is complete, pipe 3 retracts and sealing blocks 6, 7 seal the neck. After severing, the waste part 10 is removed as the pipes rise together and is ejected by air blasts down the pipe 4. Any trapped liquid may be blown out through connections between the pipes (not shown) back through the pipe 4. The package may have a cut 16 above the seal, Fig. 2 (not shown), to facilitate opening. In an alternative arrangement, carbons 17, Fig. 4, are filled by the same method through pipes 24 and 26, the cartons being formed from a blank, Fig. 5, the upper portion 19 of which corresponds to the waste portions 10, Fig. le. Folding in of the closure is facilitated by score lines 30. A modification is to connect the container to a pressure source, to maintain sterility without the necessity of a leakproof seal between the outer pipe and container.

Inventor: PHILIP WILLIAM LITTLEJOHN
IPC: B23G1/02
Filed: 1917-06-12
Abstract: 115,927. Philip, W. L. June 12, 1917. Lathes.-In a lathe particularly for turning and screwing the base-adapters of large shells, the adapter, with its rear end and the groove at the rear end of the screw already turned, is held in a chuck, the periphery of the rear end being slightly tapered towards the front to facilitate this. The saddle is traversed in one direction by a high-pressure fuid under the control of valves, and in the other by a constantly-acting fluid of lower pressure, and carries an horizontal tool-turret c leaving three or more stations. A radial grooved bearing n supports the turret, under the working tool. The turret carries at one rotation focls d having micrometer adjustment by means of hand-wheels l, for rough-turning and finishing the body of the adapter, at a second station a finishing- tool e for the front end, and at a third station a slidenut f carrying a screwing- tool g. This nut is traversed by a screwed pad- or part-nut h engaging a leadscrew i on the lathe spindle, the saddle being held up to a stop by fluid pressure during the screwing operation. The headstock carries a fluid-pressure cylinder k the ram of which carries one or two tools, one for rough-facing the front end, and the other for turning the reduced band at the front end of the screw of the adapter. These tools are brought up to the work by fluid pressure and returned by a spring m.

Title: Improvements in or relating to aerial gliding marine torpedoes
IPC: F42C1/04
Filed: 1941-04-21
Abstract: 579,844. Marine torpedoes. BURNEY, SIR C. D. April 21, 1941, No. 8463/40. [Class 9 (ii)] Relates to aerial gliding marine torpedoes having a detonating system which operates by inertia on impact. According to the invention, the detonator 3 is initially locked in a retracted position outside the priming charge 13 by means controlled by a rotary vane or like device 26 which necessitates travel of the torpedo through the air for a predetermined distance to release the detonator for rearward movement into the priming charge. Firing then takes place on impact by the inertia. action of a striker 17 on the detonator against the action of restraining means such as a spring 15 which is overcome by impact against a solid target, but not by the torpedo striking the water. In the form shown in Fig. 1, the screwed vane 26 releases a sliding rod 2 carrying the detonator 3 which is moved rearwards into the priming charge 13 when the rod or whiskers 6 are impacted. The firing pin 17, which is carried by the priming charge, moves forward against the action of the spring 15 to fire the detonator by the. sliding movement of the charge on impact. Fig. 4 shows a vanearmed detonator 14 used in addition to the usual firing device x. During passage through the air, the vane 32 rotates the screw 29 to move the detonator into the priming charge which is then fired on impact by inertia as before.

Abstract: 1467173 Treating semi-conductor devices WESTINGHOUSE ELECTRIC CORP 27 Feb 1974 [9 March 1973] 8817/74 Heading H1K The reverse recovery time and forward voltage drop of at least one semi-conductor diode of a batch of a particular type of diode, which depend on the minority carrier lifetime in the anode region, are adjusted to desired values by irradiating one or more of the diodes in the batch with electrons having an energy of 1-3 Mev. to a determined radiation dosage #. The required dosage #, appropriate for the batch of diodes, is calculated by determining the minority carrier radiation damage factor K for the particular type of diode with the given electron source of energy 1-3 Mev., determining the nominal minority carrier lifetime # 0  before irradiation in the anode region for diodes in the batch and then establishing a desired minority carrier lifetime # in the anode region of the diodes. The required dosage # for the batch is then determined from the relationship 1/#= 1/# 0  + K # . The minority carrier radiation damage factor K is determined for the particular type of diode from the slope of a plot of the measured minority carrier lifetime after irradiation with varying electron dosages for a batch of the diodes, Fig. 1. It has been found that K does not vary unacceptably from batch to batch of a particular type of diode for the particular radiation source used. In examples given the major surface of the diode adjoining the anode region is irradiated with electrons to a dosage of 1 Î 10<SP>12</SP> - 5 x 10<SP>13</SP> electrons/cm.<SP>2</SP>. The apparatus for carrying out this irradiation may be that disclosed in Specification 1,455,793.

Abstract: 622,623. Solenoid-actuated valves. STEYNOR. D. V April 1. 1947. No. 8893. [Class 1351 [Also in Group XXVII] In an internal-combination engine having a generator 14, Fig. 8, charging a battery 16 through a charging cut-out 17, an extra-air valve comprising a plunger 37, Fig. 1, seating on a washer 39, is raised by a lowresistance holding coil 24 and high-resistance boost coil 25 to allow air controlled by a manually rotatable sleeve 43 to flow through a pipe 41 connected by a flexible tube to the induction pipe. An armature plate 30 pivoted at 31, is urged by a spring 32 against a stop 35, causing a pivoted plate 47 to open contacts 52, 54 in the boost coil circuit 25. At idling, the cut-out 17 is open and the current flowing through the holding coil 24 is insufficient to raise the valve 37. As speed increases, the cut-out 17 closes and finally the current in the coil 24 causes the plate 30 to be attracted by a pole-piece 26, when the arm 47 closes contacts 52, 54, causing the boost coil 25 to lift the plunger 37 and admit extra air. A tappet 55, lifted by the plunger 37, raises the arm 47 to break the contacts 52, 54, putting the boost coil out of action, the plunger 37 being then held up by the holding coil 24 alone. If the speed drops nearly to idling, the armature 30 is released and the tappet 55 and plunger 37 drop under their own weight to cut off the extra air, but a leg 50 on the plate 47 contacts the armature 30 and prevents re-closing of the contacts 52, 54 until armature 30 is again attracted by the polepiece 26, the voltage at which this occurs being controlled by the spring 32 and adjustment of the stop 35. A switch 66 short-circuits the coil 24 when closed and prevents opening of the valve 37, and the generator field winding 68 is energized through a constant voltage regulator 67.
