Patent GB-311426-A (GB)
Title: Improvements in and relating to servo devices for automobile vehicles
IPC: B60T13/74
Filed: 1929-05-11
Abstract: 311,426. Bethenod, J. May 12, 1928, [Convention date]. Actuated or applied by running axle; electric and magnetic. -In an automobile in which the brake, clutch or other apparatus associated with the vehicle is arranged to be actuated by a driving member, through the intermediary of a magnetic coupling device located between the driving member and the operating member of this apparatus, the effort exerted by the driver is directly transmitted mechanically to the apparatus to be actuated, the reaction of this effort being used to control the effort exerted by the coupling device, so that the two efforts are proportional to and supplement one another. The brake pedal 1 is directly connected to the brakes by a floating lever 3 and a rod 4, the free end of the lever 3 operating the plunger 8 of an adjustable rheostat 6 having an insulating lining and containing carbon plates 13. The rheostat is in series with a battery 9 and the winding of an electromagnetic pulley 14 by means of a brush and a collector ring 11. When the pedal 1 is depressed the lever 3 pivots about the point 5 to apply the brakes directly, until the resistance of the brake shoe is sufficient to overcome the rheostat spring 12, whereupon pressure is exerted on the plates 13, reducing the electrical resistance thereof and allowing a current to flow through the pulley 14, which being mounted on a pivoted lever, is drawn against the action of a spring against the flywheel 17. The pulley is thereupon rotated and also another pulley 18 on which is wound a rope 19 connected to the brakes. The pulley 15 may act on the circular or the cylindrical faces of the flywheel. Adhesion may be increased by the provision of grooves. A device may be provided to limit the retarding effort of the pulley on the flywheel to prevent stalling of the engine. Mechanism for control of a vehicle clutch is progressively controlled by a manually controlled adjustable rheostat. The coupling device may be of the single or multiplate type and may utilize the effect of Foucault currents. The Specification, as open to inspection under Sect. 91 (3) (a) also describes a friction wheel of para-magnetic material adapted to engage a ferro-magnetic hub on the transmission shaft. The movement of the wheeel is transmitted to the brake rigging by a cable, chain, rods, or levers. The wheel may be mounted on the transmission shaft and the other co-operating member of the device may be constituted by a ferromagnetic roller or a plate of magnetizable metal which tends to be displaced in a plane tangential to the cylinder when the latter is magnetized. In another arrangement, an electromagnetic shoe is arranged to engage the flywheel and be angularly displaced. Declutching is automatically effected as soon as the accelerator pedal, when released, closes a contact in the circuit of the coupling device. This subject-matter is not contained in the Specification as accepted.

Title: Improvements relating to output storage systems for use with electronic digital computers
Inventor: FREER JOHN ANTHONY
IPC: G06F3/08
Filed: 1959-05-01
Abstract: 921,084. Record-card apparatus. FERRANTI Ltd. April 22, 1960 [May 1, 1959], No. 14862/59. Class 106 (1). The output of a computer (for example in punched card form) is checked by reading each block back into a store and comparing it with the contents of one of a pair of stores used alternately as duplicate output buffer stores. Fig. 1 shows four 80-column 12-row magnetic core matrix stores 1-4 for use in punching 80-column cards. Each column of information from the computor is staticized in 5 and 6 and then read into its column of 1, and 2 or 3, by a ¢-write pulse from shift register 9, the stores 2 and 3 being selected for alternate card blocks by 12 and 15. When the first block has been written into 1 and 2 (say) it is read out from 1 row-by-row and punched into a first card, and the next block is then written into 1 and 3. 1 is now read out again and punched into the second card, and simultaneously the first card is read and the first block entered into matrix 4. Stores 2 and 4 are now read out column-by-column and their contents compared; an alarm is generated if they are not identical. Next the third block is written into 1 and 2 and then punched out from 1, and the second block written into store 4 for comparison, this time with store 3, and this process is repeated.

Title: Thermally stabilized alkylled compositions
IPC: C07F7/24
Filed: 1961-04-25
Abstract: Alkyl lead compounds may be stabilized against thermal decomposition at temperatures between 180 DEG  and 195 DEG C. by the addition of an alcohol and an organic phosphate ester, the alcohol being a C1 to C18 alkanol and the ester having in the molecule 3 organic ester groups each containing 1-10 carbon atoms. The preferred alkanols contain six or less carbon atoms, isopropanol being especially preferred, and the preferred esters are those containing methyl, phenyl, tolyl, cresyl or xylyl groups, the aryl dimethyl phosphates showing superior engine performance characteristics.  For every 100 parts by weight of alkyl lead it is preferred to use 3-45 parts by weight of alcohol and 2-50 parts by weight of phosphate ester.  If desired, the ester groups may be substituted by halogen or oxygen atoms or nitro or amino groups, and the alcohol may be a mercapto or oxy-alcohol.  Other stabilizers such as 1,2,3,4-tetrahydronaphthalene, anthracene and naphthalene may also be present.

Abstract: 1,249,265. Edge runner mills. KOMBINAT FORTSCHRITT LANDMASCHINEN NEUSTADT IN SACHSEN VEB. 31 March, 1970, No. 15148/70. Heading B2A. A crushing machine comprises a circular grating 3 resting on a support, a drive for rotating a crushing member 5 (i.e. a roller) about the centre of the grating 1 and a detector which detects angular displacement of the circular grating relative to the support. Bulk material is fed to the machine via a chute 8 and crushed against the grating, and when resistance to rotation of the member 5 exceeds a predetermined value the circular grating 3 is so angularly displaced as to cause the detector to disable the drive. The detector comprises a roller 13 rotatable about a pin 18, and coupled to a switch 7. A guide member 15 contacts the roller when a portion of a mill-cover 6 in which the switch is mounted is closed. Adjustable pressure screws 17 permit the frictional force opposing angular displacement of the die or grating 3 to be varied. Movement of the grating rotates the roller to bring a flap 14 in opposition to the grating, thus operating the switch.

Filed: 1958-05-12
Abstract: 829,982. Paper tubes. SONOCO PRODUCTS CO. May 12, 1958, No. 15182/58. Class 99(2). In a multiply, helically wound paper tube 10 for moulding concrete columns the innermost ply 12 has a liner coating 14 applied thereon that is resistant to the abrasive action of the concrete when poured and that covers all of the fibres of that ply so as to facilitate stripping of the form when the concrete has set. The coating is provided with fine, closely spaced, perforations 16 arranged uniformly throughout the entire extent of the coating for allowing absorption of mositure by the innermost and adjacent plies of the tube initially from the poured concrete and thereby obtaining a uniform swelling of the tube during the initial setting of the concrete that eliminates subsequent adhesion of the tube to the concrete after setting. As shown, the coating 14 is of polyethylene, and a waterproof barrier ply 22 comprising two paper strips and an intermediate asphalt base binder interposed therebetween is applied over the plies 12, 18 and 20. Additional plies 24, 26 having butt or overlapping joints are wound overall. Specification 751,490 is referred to.
