IPC: B21C23/21
Filed: 1960-11-29
Abstract: 944,251. Extruding. LOEWY ENGINEERING CO. Ltd. Nov. 29, 1961 [Nov. 29, 1960; Feb. 23, 1961], Nos. 41003/60 and 6619/61. Heading B3P. In a billet extrusion press of the type having hydraulic drive for the billet container and a movable tool or die carrier placed between the container and a platen, hydraulic plungers are placed between the adjacent end faces of the container and carrier so as to forcibly separate them; thus billet residue can be unstuck from its container without subjecting the tool or die carrier to a bending moment. In the embodiment shown in Fig. 1, the platen 10 is connected by four columns (Fig. 2, not shown), to a main hydraulic cylinder (not shown). The billet container 12 is movable along the press axis X-X by hydraulic means. The die carrier 13 is in the form of a long beam rotatable, about one of the machine columns, in a plane perpendicular to the axis X-X. A die or tool is mounted on each end of the arm, and associated with each mounting is a pair of hydraulic units 15, 16. When the billet container 12 is withdrawn by means of its hydraulic gear, the hydraulic units 15, 16 are also actuated to separate the die from the billet without bending of the die-holder arm. In a second embodiment, Fig. 3, the hydraulic separating units are mounted on the main ram 23 and exert separating pressure on the die through spring returned plungers 17. The die carrier may be in the form of a turntable having more than two die and/or toolcarrying stations.

Title: Improvements in or relating to brake force regulators
Inventor: VANA OLDRICH
IPC: B60T8/18
Filed: 1968-08-28
Abstract: 1,205,294. Load-dependent brake-force regulators. AUTOBRZDY JABLONEC NARODNI PODNIK. 28 Aug., 1968 [30 Aug., 1967], No. 41127/68. Heading F2F. In a load-dependent brake-force regulator incorporating a differential piston and a regulating piston, the regulating piston being subject to a force dependent on the vehicle load, the regulating piston is coaxial with the differential piston, and the distribution space, connected to the brake cylinders and defined in part by the shoulder formed between the larger and smaller heads of the differential piston, is connected by a passage in the smaller head with the regulating space, which is formed between the smaller head and the regulating piston. As shown, a differential piston 8 has a larger head 9 accommodated with clearance in a bore 5 provided in a body 1 attached to a sprung portion of the vehicle (e.g. the frame). The larger head 9 has a resilient packing 10 for engagement with a seat 11 formed where the bore 5 joins a bore 7 of less diameter. The differential piston 8 has a reduced central portion 12 forming, with part of the bore 7, a distribution space 20 having connections at 21, 22 to brake cylinders (preferably for the rear wheels). Finally the piston 8 has a smaller head 13 slidable in bore 7, an axial hole 25 and a transverse hole 26 to connect the distribution space 20 with the region 24 below the smaller head 13, and a central protuberance 17 at the top of the larger head surrounded by a cup spring 18. Below the piston 8 is a regulating piston 14 having at the top a central protuberance 23 and, at the bottom, a recess 28 for accommodation of a rod 29 pivoted to an arm 31 attached to a helical torsion spring 32 which is connected with the axle. On application of the brake, master-cylinder fluid entering at 4 depresses piston 9, 13 slightly, then flows via 19, 11, 20, 21, 22 to the rear brake cylinders. Some fluid passes via 26, 25 to the regulating space 24, depressing regulating piston 14 against the force of torsion spring 32 until head 9 reaches seat 11; thereafter, no more fluid flows to the rear brake cylinders. If, at the moment of braking, the rear axle is relieved of load by movement of the vehicle weight towards the front axle, the effective force of spring 32 is reduced, so the volume of the regulating space is increased, with consequent reduction in rear brake pressure and less tendency to wheel locking. If, on braking, the rear axle load is on the other hand increased, the spring force is increased, and the rear brake pressure is consequently increased. If the increase in spring force is large, piston 9, 13 is raised until head 9 is lifted off seat 11, so inlet space 19 is connected to the rear brake cylinders again, until equalization of pressures occurs. On brake release the parts resume the positions shown.

Abstract: 1283096 Adsorptive extraction of condensables from hydrocarbon gases CONTINENTAL OIL CO 19 Aug 1969 [19 Aug 1968] 41416/69 Heading B1L [Also in Division C5] In the cyclic extraction of condensables from a hydrocarbon feed gas an adsorbent e.g. activated charcoal is cooled after regeneration by reacting a cool stream of gas over the adsorbent to prevent waste of any remaining unvaporised condensables. Adsorbents 1, 2, and 3 are interchanged so that they spend an equal time in the adsorbing, regeneration and re-cooling steps. As shown raw feed gas is fed to cool adsorbent 1 via pipe 4 and condensate-stripped residue gas removed at 5. At the regeneration step adsorbent 3 is regenerated by incoming heated gas from pipe 6 whereupon the adsorbed condensables are vaporised and carried through cooler 8 and separator 10 for condensation and separation before being removed at 23. The regeneration gas is re-cycled via conduit 11 and heater 14. At the adsorbent cooling station cooled gas is fed to hot regenerated adsorbent 2 via conduit 15. Effluent gas then passes via conduit 19 to cooler 19 and is re-cycled to the adsorbent 2. A pressure check valve 22 permits gas flow only from conduit 4 to conduit 15. Prior to cooling the adsorbent 2 may be purged e.g. with feed gas, stripped gas from 5 or a "lean" gas.

Title: Method of decontaminating reclaimed paper
IPC: D21D5/18
Filed: 1969-08-21
Abstract: 1,206,550. Centrifuging paper stock. BERGSTROM PAPER CO. 21 Aug., 1969 [4 June, 1969], No. 41708/69. Heading B2P. In a process of de-contaminating reclaimed paper, a slurry of water and defibered, contaminated fibre stock obtained from the paper is fed into a hydrocyclone to create therein a vortex and a first part of the slurry relatively enriched by fibres is extracted from an outer region of the vortex while the remainder of the slurry relatively enriched by contaminants is extracted from an inner region of the vortex. The migration of the fibres to the outer region of the vortex, while the contaminants are left in the outer region, may be obtained as a result of the relation existing between the cross sectional size of the overflow and underflow outlets. In a typical example the diameter of the overflow outlet is 5/8" and that of the underflow 1/2". The slurry may have a consistancy of 0.10% to 1.50% and may be fed at a pressure of 40 to 100 p.s.i.g. The contaminants include those with a specific gravity less than that of water, e.g. plastics polymers, adhesives, &c. and those with a specific gravity greater than that of water and that of fibres, e.g. clays, pigment fillers and ink particles. The latter because of their minute size and/or platelike shape have a higher coefficient of hydraulic, drag as compared with the fibres, and are therefore held back in greater degree that the fibres from their natural tendency to migrate to the outer portion of the vortex.

Filed: 1973-09-05
Abstract: 1437111 Pulse circuits AUTOMATIC POWER Inc 5 Sept 1973 41857/73 Heading H3T [Also in Division G4] A set of buoys have their lamps switched on in synchronism or sequence by respective monostable circuits 18 triggered by pulses from a counter 16 driven by one-second pulses from a master oscillator source 15 and synchronism of the counters is effected by receipt of radiated signals. These signals comprise a 100 Hz toneburst of 10 seconds and if a sync. signal detector 21 at the buoy detects a burst longer than a given duration it produces a counter reset pulse at the end of the burst. The sync. signal detector Fig. 3 produces a pulse E only if input D is at least eight seconds long: during pulse D a capacitor C1 is charged by a circuit which includes a transistor-inverter Q1 and a transistor Q2, the voltage at the base of the latter being low thereby biasing it off and voltage on capacitor C1 rises. When such voltage reaches a predetermined level, set by a Zener diode Z1 to correspond to charging for eight seconds, a pulse E is produced and continues for the remainder of the time pulse D is present. Signal E turns on a transistor Q3 and transistors Q4, Q5 turn on. A negative spike F is produced at the trailing edge of pulse D by a capacitor C2 to briefly turn off transistor Q5 thereby producing a positive pulse C to simultaneously reset each stage of counter 16, Fig. 2. Thus all buoys flash simultaneously despite oscillator 15 stability not being very high. The radio signal may be emitted from a "master" buoy, the output pulse A keying a tone modulator, Fig. 4 (not shown). Sequential light emissions are effected by a delay circuit between counter 16 and multivibrator 18, Fig. 6 (not shown).
