Abstract: 1,262,592. Electromagnetic couplings and brakes. NATIONAL CASH REGISTER CO. 5 Feb., 1970 [18 Feb., 1969], No. 5576/70. Heading H2A. An intermittent rotary motion device comprises a rotatable system whose input is resiliently coupled to its output, the input being rotated at constant speed, a magnetic oscillator for superimposing a torsional oscillation on the constant rotation of the output, the frequency of oscillation being equal to the resonant frequency of the rotatable system, and a rotatable output member adapted to be coupled to or uncoupled from the output of the rotatable system. In the embodiment shown, the rotatable system comprises a resilient shaft 28 carrying a rotor 72 on its output end and whose input end 32 is driven at constant speed by a belt 34. The oscillatory motion is imparted by a D.C. excited toothed stator 40 co-operating with teeth 74 on the rotor 72. The oscillation is such that during each cycle, the rotor 72 instantaneously becomes stationary and 180 degrees later is rotating at twice the speed of the input end 32 of the shaft. The rotatable output member comprises a shaft 80 arranged to be coulped to the rotor 72 when the latter is instantaneously stationary so as to intermittently drive a paper or other tape 118. The coupling is effected by a clutch comprising a winding 110 and teeth 108 on the rotor 72 and teeth 114 formed on a member 78 carried by the shaft 80. The shaft 80 may be held stationary, after rotor 72 has instantaneously come to rest, by a brake comprising a winding 102 and teeth 100 on a frame 70 and teeth 98 on the member 78. In a modification, Fig. 5 (not shown), a second clutch, similar to that shown, may be energized at an instant when rotor 72 (and hence shaft 80) is rotating at twice the speed of the input 32 of the shaft 28 to couple shaft 80 to a second input member 174 rotating continuously at this higher speed. In a further modification, Figs. 6, 7 (not shown), basically similar to Fig. 4, the stator teeth of the brake and of the magnetic oscillator are angularly adjustable.

Abstract: 640,254. Controlling change-speed gearing. ROLLS-ROYCE, Ltd. Feb. 27, 1947, No. 5714. [Class 80(ii)] In a change-speed gearing, in which a change in ratio is effected automatically by a clutch on synchronism, driven by a multicylinder internal combustion engine, means are operative to cut-off the ignition to some of the cylinders during a period including that immediately after the engagement of the cluth. The third/fourth speed change of the gearing of Specification 640,228 is effected by a fork 5 moved by an armature 4 of a solenoid 1 having a pull-in winding 2 and a holding winding 3, a second armature 6 being provided which is drawn upwards by the solenoid tq close a pair of contacts 11 to disable the ignition coil 17 and is carried downwards by the armature 4 on full travel to break the contacts 12 of the pull-in winding. The dual contact breaker 18 has one blade 19 fed directly from the coil 17 and the other 19a through a solenoid actuated switch 20 normally closed. To change from fourth to third speed, the accelerator is depressed to close the switch 15 which energizes the solenoids 14, 21, the switch 22 being closed when the gear lever is in the "top " position. Contacts 13 are closed, energizing the windings 2, 3 to raise the armature 6 to cut off the ignition and then on synchronism the armature 4 moves against the spring 10 to shift the clutch and then move armature 6 to reinstate the ignition and also de-energize the winding 2. The switch 15 still being'closed energizes the solenoid 21 to open the switch 20 and thus disable half the ignition system until the accelerator is partially released, which opens the switch 15 thereby de-energizing the winding 3 and allowing the switch 20 to close, the gear remaining engaged against the pressure of the spring 10 .by the baulking device on the clutch. Change in the other direction is automatic when synchronism frees .the baulking device.

Abstract: 1470918 Extruded porous pipe SOUTHLAKE PIPE CO 12 Feb 1975 [26 Feb 1974] 6048/75 Heading B5A [Also in Divisions F2 and A1] A porous pipe made from a granulated elastomer and a binding material incorporates a plurality of irregularly shaped apertures closely spaced at random along the length of, and around the circumference of, the walls of the pipe.  The pipe is produced by a process of extruding a mixture of elastomer and binding through a pipe forming die, the apertures being blowformed as the pipe leaves the die, from steam produced by water absorbed in the granules. In a preferred embodiment of pipe the granulated elastomer which makes up 70% of the product mix is a reclaimed vulcanized material, such as shredded car tyres, having a granule size of less than one sixteenth of an inch before mixing with the binder which comprises high density polyethylene, vinyl, ABS and attaclay and which makes up the remaining 30% of the product mix. The apertures in the form of labyrinthine channels are achieved by blow forming chiefly when water absorbed by the granules is turned to steam on heating and also due to the pressure change at pressure head screen 33.  The pipe is manufactured by extrusion from a two stage wave screw extruder 18, the product mix being fed from a hopper 19 to wave screw 20, which extends substantially the length of cylinder 21 and is driven by motor 22 and gear train 23. Heating and cooling cylinder barrels 24 are arranged around the cylinder 21, heating being achieved by cast-in resistance elements and cooling by cast-in cooling coils and a vent 31, connected to a vacuum control 32 is located on the cylinder 21. The extruder die (Fig. 5) comprises pressure head screen 33, thin vanes 41 extending from a mount ring 42 to base 44 which also houses a mandrel 43 forming the inner surface of the pipe and which has an internal bore connecting with passage 46 for venting purposes. The appropriate temperatures of the mix are: after input to the wave screw 300 F., increasing to 350 F. at vent 31 and thence cooling to 300 F. after venting rising again to 350 F. approaching the pressure head screen 33 at a pressure of 2,000 to 3,500 p.s.i. After extrusion the pipe enters a cooling trough containing water at 35 F. and is drawn therefrom by rubber rollers on to a reel pipe coiler. The granulated material may comprise from 60 to 90% of the product mix while the binder makes up the remainder being comprised of any of polyethylene (high density), vinyl, ABS and attaclay.

Title: Improvements in and relating to electric switches with self-generated arc-extinguishing gas blast
IPC: H01H33/76
Filed: 1937-03-01
Abstract: 469,006. Gas-blast switches. BRITISH THOMSON-HOUSTON CO., Ltd. March 1, 1937, No. 6073. Convention date, Feb. 28, 1936. [Class 38 (v)] In a circuit-breaker employing an arc-extinguishing tubular chamber 1 having walls formed of a solid material capable of developing a quenching- gas due to the heat of the arc 13 produced within the chamber during the separating movement therethrough of a movable contact 3 away from a fixed contact 2 located at or near one end of the chamber, the movable contact 3 being adapted to enter through the other end of the chamber which it maintains substantially closed to blow-out of gas except when withdrawn a predetermined distance from the fixed contact, the wall structure of part of the chamber neighbouring the fixed contact is formed so as to provide passageways for ensuring a lengthening and transverse blowing of the arc upon the initiation of the latter, and a byepass escape for the gas prior to the contact 3 reaching the position in which it opens the blow-out end of the chamber. As shown, the passageways are formed between spaced discs 5 of the gas-evolving material, which discs are apertured at 9 and lead into ducts 10 in an unsubdivided piece 4. The apertures 9 may either be superimposed, as shown, or out of register in a spiral formation. The movable contact is of tubular form and surrounds an insulating pin 7 which also may evolve gas. A packing-member 11 prevents escape of gas along the contact 3, and further ensures that an extinguishing blast flows when the latter has moved past it. The size of 9, 10 is such as to ensure an adequate pressure being set up for quenching heavy-current arcs, whereas the lengthening and transverse blast ensure extinction of medium and small current arcs.
