An expanding V-belt pulley of a motor-vehicle change-speed gear, has one flange 18 axially displaceably controlled by a piston/cylinder assembly, the cylinder, integral with the movable flange 18, being divided by the piston 21, integral with a shaft 19 of the other pulley flange 20, into two chambers 17, 22 separately connected via ducts 16, 27 and a dual changeover valve 2, 7 to atmosphere or engine manifold depression, the valves 2, 7, spring biased (as shown) to connect the ducts 16, 27 to atmosphere, being moved by solenoids 3, 8, to connect the ducts 16, 27 to manifold depression, respectively energized on closure of switches 4 and 9 or 11 incorporated in the engine throttle valve 5 and vehicle brake system respectively and controlled in dependence on driving conditions. As shown, the switch 4 is open only at the fully open or shut throttle positions to connect the chamber 17 to atmosphere to establish low ratio, intermediate throttle positions maintaining the switch 4 closed and the solenoid 3 de-energized to connect the chamber 17 to engine depression whereby the pulley is adjusted to provide higher ratios for normal driving. The switch 9 is closed to connect the chamber 22 to engine manifold depression to establish low ratio whenever the vehicle braking system is applied, and the brake switch 11, overriding the switch 9, may be operated to similarly establish low ratio for engine braking during a gradient descent. A centrifugally operated switch 25, on a flexible speedo-shaft, i.e. responsive to vehicle road speed, is incorporated in the solenoid 3 circuit associated with the throttle valve whereby ratio change is dependent on the vehicle speed. A further centrifugal switch 26 responsive to engine speed is included in the solenoid 7 circuit associated with the vehicle braking system and opens when engine speed falls below a predetermined level.

Title: Target strike display apparatus
IPC: G01S5/22
Filed: 1971-12-21
Abstract: 1387836 Acoustic position-finding DEFENCE SECRETARY OF STATE FOR 5 March 1973 [21 Dec 1971] 59323/71 Heading H4D A device for indicating the position of a projectile relative to a target comprises electroacoustic transducer means arranged along opposite sides of the target plane, the transducers feeding time measuring means started by passage of the projectile through the target, the difference in times measured by the time measuring means of a particular transducer pair being obtained to obtain a position co-ordinate of the projectile, a visual display means being provided to display the projectile position. Target plane 10 is provided with, e.g. piezoelectric, transducers 14, 16 and 18, 20 feeding time measuring means 28, 30 and 32, 34. The time measuring means feed detecting means 38, 40 for obtaining the difference between the times measured. The detecting means provide signals for a display 42. As the projectile passes through plane 10 at position 44, a sound wave will be generated and will read, e.g., transducer 16, before transducer 14. Receipt of the wave at transducer 16 causes means 30 to start counting pulses from generator 36. Eventually the wave reaches transducer 14 and means 28 then starts counting. When means 30 reaches a predetermined maximum count, both counters stop and the difference in counts is related to co-ordinate x. Similarly, transducers 18, 20 provide coordinate y. The signals representing the count difference are fed to plotter 42 which determines the co-ordinates and displays position 44 on a replica 43 of the target. The plotter may be replaced by a C.R.T. having a storage display. The transducer means may be single elongated elements or may each consist of a number of separate transducers. If each transducer means comprises a number of separate transducers, only one pair of transducer means may be needed. In this case one co-ordinate is determined as above and the other co-ordinate determined by noting which transducer pair in the transducer means received the sound. The target origin 23 may be anywhere within the plane 10, the time measuring means being given initial counts to compensate. The time measuring means may be arranged so that only one means of a particular pair is limited to a maximum count.

Title: Process for the continuous graphitisation of carbon filaments, carbon fibres, carbon fibre strips and carbon yarn
Inventor: WEISBECK ROLAND
IPC: D01F11/16
Filed: 1970-12-23
Abstract: 1298043 Graphitization of carbon fibres BAYER AG 23 Dec 1970 [27 Dec 1969] 61115/70 Heading C1A [Also in Division H5] A carbon filament, fibre, fibre strip or yarn is continuously graphitized by passing it continuously through a plasma produced by one or more gas discharges having gas temperatures above 1000‹ C., and having substantially symmetrical properties about the line along which the filament is passed. The plasma gas may be one or more noble gases, e.g. argon (to which may be added N 2 , H 2 , NH 3 , CH 4 , C 2 H 2  or C 2 N 2 ) and the plasma may be produced by inductivelycoupled high-frequency discharges, unipolar high frequency or microwave flare discharges or by direct current arc plasma torches (optionally with an A.C. arc) (see Division H5). The filament may be graphitized under tension by using pairs of feed and draw rollers before the inlet and behind the outlet of the plasma chamber. Maximum filament temperature may be below the maximum gas temperature, and may be controlled by adjusting gas pressure, speed, composition and electrical parameters, or by altering filament speed, or by impregnating the filament with a substance vaporizable in the plasma. Such substances are salt melts, aqueous salt solutions, inorganic acids, hydrocarbons, oils, resins, pitch or tar. The process may be operated at 1 to 1000 mm. Hg, preferably atmospheric pressure. In examples, (1) a carbonized fibre strip (6000 individual fibres) is graphitized at 2500-2900‹ C. using 60% Ar, 35% N 2 , 5% H 2  as plasma gas; (2) carbonized polyacrylonitrile strip (5000 fibres) is graphitized at 2400-2600‹ C. using 90% Ar, 5% NH 3 , 5% C 2 H 2  as plasma gas; (3) carbonized polyacrylonitrile strip (3000 fibres) is impregnated with a mixture of diphenylether, diphenyl and benzene before graphitization at 2500-3000‹ C. using pure Ar as plasma gas.

Title: Ion accelerators and energy transfer processes
IPC: H05H9/00
Filed: 1978-08-04
Abstract: Ions are accelerated by subjecting them to the electrodynamic effects of a driving circuit comprising a separate closed circuital current which in one circuit segment comprises an electron flow in a conductor and in another segment of the same circuit comprises at least partially a flow of ions. The invention applies a general law of electrodynamics published in the Journal of the Franklin Institute in 1969 at page 179 of volume 287 which concerned anamalous cathode forces attributed to the action of electrons upon ions carrying current in the same closed circuit. The invention also has application to energy transfer processes dependent upon the catalytic action of high energy ions. Various apparatus is disclosed. In Fig. 11, for example, the driving circuits 55, 56 comprise cold cathode gas discharge systems excited by high voltage pulse generators 57, 58, and they accelerate ions from sources 61, 62 towards the centre of the housing 54. Cooling jacket 69 extracts heat from the housing and supplies it to power generator 70. In another arrangement two adjacent oppositely directed ion beams serve as the driving circuit for each other. <IMAGE>

Title: Roasting cocoa
IPC: A23G1/02
Filed: 1978-09-26
Abstract: A process for the continuous roasting of cocoa kernel material, for example cocoa kernel paste or cocoa liquid from raw, shelled, pre- dried, broken and crushed cocoa beans comprises applying liquid cocoa paste for roasting continuously in a thin layer onto a surface over which the paste runs and flushing with a gas flowing in counter-current. Heat is generated in the thin layer of paste by friction and the paste is constantly partially lifted out of the layer and returned to the layer, to which hot air is supplied in countercurrent along and through the region of return of the paste, whereby the paste is brought to roasting temperature in a first phase and then kept at roasting temperature in a second phase and the temperature of the paste is lowered in a final phase. The process provides considerable economic advantages in comparison with conventional processes because of an increase in aroma yield and flavour quality, a saving in cocoa paste, prevention of loss of cocoa butter and reduction of the time required to tumble the roasted paste in a conche.
