Title: Fluidpressure operated anti-skid braking systems
IPC: B60T8/34
Filed: 1976-07-27
Abstract: The brake system has two separate control valves (1, 2), which are connected to one another and are arranged in series in a pipeline between a pressure medium source and a brake. Each control valve (1, 2) contains a valve (13, 22) responding to the deceleration, for actuating the assigned control valve (1 or 2) independently of the other (2 or 1) or simultaneously with the other control valve (1, 2) as a function of the deceleration of the braked wheel. The rear valve (2) in the direction of flow is circumvented by a bypass arrangement (26), which makes a direct, throttled connection between the front valve (1) and the brake. In operation, after actuation of the brake, the fluid flow to the brake is regulated by the two control valves (1, 2). When the predetermined value for deceleration of the wheel is exceeded, the device with the two valves (13, 22) and the bypass arrangement (26) comes into operation in order to reduce the fluid pressure under conditions such that, whilst maintaining the same wheel adhesion, locking of the wheel is prevented. <IMAGE>

Abstract: 1283268 Time-cost computing APT CONTROLS Ltd and R G STONE 23 June 1971 [29 June 1970] 31295/70 Heading G4T In a system for computing the fee for using a facility (e.g. a car park) between first and second times, wherein (a) a succession of electrical pulses are generated and counted, (b) a ticket issued at the first time carries an indication of the count at that time, (c) this indication is read at the second time and a number of pulses (proportional to the fee) are added to the reading until the adjusted reading is equal to the counted succession of pulses at the second time, and (d) the fee is displayed, a programmer under the control of a time switch changes the frequency of the generated pulses, e.g. to increase the charges for car parking during certain times of the day. The pulses generated at 10, 11 and controlled at 12 by the programmer 14 and a time switch 15 are uninterruptedly fed to a master counter 13 and slave counters 13a-13d. Entry of a car into the car park is sensed at 18 to initiate the issue of a ticket 17 bearing an indication of the count from slave counter 13a at the time of entry. To leave the car park, the recorded count is read from the ticket at 20 and entered into counter 21. This entered count is increased by pulses fed from 22 until comparator 23 senses parity between the value stored in 21 and the count registered in slave counter 13b at the time of leaving. Comparator 23 then closes a gate 25 to stop the feeding of pulses from 22 to a bi-directional counter 26, the latter then storing a number proportional to the fee payable. The overall cost of parking can be adjusted at 24. The fee is displayed at 27. The user inserts coins at 29 until the number stored in counter 26 and the amount displayed at 27 are reduced to zero, whereupon a ticket bearing the count at this time is issued at 31. Provided that this ticket is presented at 32 within a given time from its time of issue, barrier 35 opens. If this given period of time is exceeded a display 36 is actuated to indicate that a further fee is payable.

Title: Method for imaging and for recording information
IPC: B41M5/26
Filed: 1972-07-19
Abstract: 1405628 Photographic processes ENERGY CONVERSION DEVICES Inc 19 July 1972 [19 July 1971] 31506/72 Heading G2C [Also in Division C2] A process for producing negative images comprises imagewise exposing a material containing a layer including a compound in which at least one element E selected from the elements having an atomic number above 20 and of groups IB, IIB, IIIA, IIIB, IVA, IVB, VA, VB, VIA, VIB (except Po), VIIA and VIII of the periodic table to form a latent image and developing the latent image (normally by heating) to produce an image consisting of the element E. Alternatively, positive images are produced by either (i) adding a stabilizer to the material which stabilizes on imagewise exposure and/or development reacts with the compound so element E is not produced and then applying heat to produce element E in the unexposed areas (presumably by decomposing the compound) or (ii) adding a trap-former to the material which trapformer on imagewise exposure prevents latent image formation and then developing to produce element E in the unexposed areas. Positive or negative images of element E may be produced by adding a negative or positive working photo-resist to the material, imagewise exposing and developing to produce a negative or positive resist and then reducing the compound to element E in the resist. Electrostatographic negative images may be produced if an electrically conductive support is used and the image of element E produced by the first method above is electrically conductive and is in an insulating binder, by heating further to remove the binder in the exposed, conductive areas, electrostatically charging so that the unexposed areas retain the charge, toner developing and transferring the toner to a receptor sheet. As particularly described, a Te compound of Formula X admixed with acetophenone (to make it sufficiently sensitive) and cyanoethylated starch as binder is imagewise exposed to a flash-gun and developed by heating to form a negative image of Te. Alternatively, the compound of Formula X may be replaced by one in which the acetophenone groups are replaced by acetone or 1, 4-diacetophenone groups, and acetone and 1, 4 diacetophenone respectively are used as sensitizers or wherein Te is replaced by Se as the central atom.

Title: Improvements in governing mechanisms
IPC: F01D17/26
Filed: 1939-12-07
Abstract: 536,242. Fluid pressure servomotor-control systems. BRITISH THOMSON-HOUSTON CO., Ltd. (General Electric Co., Ltd.). Dec. 7, 1939, No. 31674. [Class 135] A governing-mechanism has a controlled element actuated by two hydraulic power devices, one of which has a delayed action, both devices being controlled by a single control valve actuated by the controlling impulse. Fig. 2, shows the invention applied to the control of a turbine supply valve in accordance with the pressure in the turbine exhaust. The turbine supply valve is operated by a doubleacting piston with piston valve and floating- lever follow-up control. The piston valve is actuated by a rod 15 loaded by a spring 56 and provided with a pointed end engaging a recessed block 54 mounted on the rigid end wall 53 of a bellows 49. The bellows is secured to a short flanged cylinder 50 clamped to the casing 21 by a cover 51 and bolts 52. Pressure fluid is supplied to the chamber surrounding the bellows by a pipe 64 fitted with a restriction 65 and the pressure is varied by a leak-off valve 38, the exhaust fluid passing by way of passages 66 and chamber 68 bolted to the casing to a discharge pipe 67. A block 45 supported by arms 44 and spring arms 42 or a diaphragm has a hemi-spherical part engaging a similar recess on the back of the valve and has a recessed seat adapted to receive the pointed end of an adjustable strut 37. The other end of this strut engages a recessed block 36 in a lever 33 mounted on a pivot 34. A bellows 27 secured to a fitting 25 is subject to the turbine exhaust pressure admitted through a pipe 14 and is connected to the lever by a strut 31. The lever is loaded by a spring 84 adjusted by a screwed spindle rotatably mounted in the casing and co-operating with a movable abutment 85 guided by pins 87 and by two other springs 59 82 acting on opposite ends of the lever. The spring 59 has an intermediate convolution secured to a screwed part of the rod 15 by a clamp 61 while the spring 82 is similarly connected to a rod 80 adapted to be actuated by a bellows 71 similar to the bellows 49. The chamber surrounding this bellows is connected by a passage 73 fitted with a throttle 74 to the passage 39 controlled by the valve 38. With an increase of pressure in the pipe 14 the valve is moved towards its closed position to increase the pressure on the bellows 49 and initiate the closing of the turbine valve. At the same time pressure slowly builds up beneath the bellows 71 to give an increased movement to the valve 38.

Title: Improvements in the recovery of sulphur as hydrogen sulphide from iron-sulphide bearing material
IPC: C01B17/06
Filed: 1947-12-01
Abstract: Hydrogen sulphide is recovered from iron sulphide-bearing ore by smelting the ore to form a matte containing ferrous sulphide and a large part or substantially all of the sulphur of the original ore, treating the finely divided solid matte with aqueous sulphuric acid to produce hydrogen sulphide and aqueous ferrous sulphate, collecting the hydrogen sulphide, decomposing the ferrous sulphate from the solution to produce essentially a mixture of sulphur dioxide and trioxide, and utilizing the sulphur dioxide and trioxide to regenerate the sulphuric acid used in treating the matte.  The matte may be treated at above 25 DEG  C., say 50-70 DEG  C., countercurrent in a series of vats by continuously introducing raw matte into the first vat and acid into the last vat of the series to produce a neutral ferrous sulphate solution and a solid residue of sulphides of cobalt, copper, gold, nickel, platinum, silver or zinc.  Part of the zinc may be recovered as zinc sulphate at an intermediate stage.  The solid ferrous sulphate, recovered by evaporating or cooling the solution, may be dehydrated in a rotary kiln at 400-450 DEG  C. in a countercurrent of hot gas passed in contact therewith.  The anhydrous product may be heated in a muffle furnace out of contact with air or combustion gases at 480 DEG  to 1300 DEG  C. by hot combustion gases and the waste gases may be passed to the rotary kiln.  The sulphur dioxide in the sulphur dioxide/trioxide mixture from the muffle furnace is oxidized to sulphur trioxide and all the sulphur trioxide is absorbed in concentrated sulphuric acid.  Specifications 566,375, 656,141, 656,142, 656,143 and 656,146 are referred to.

Abstract: 895,056. Pipe couplings. BEESTON, J. P. Sept. 15, 1960 [Sept. 17, 1959], No. 31731/59. Class 99(1). In a quick-release coupling of the kind comprising a spigot 7 on one coupling element B adapted to enter a socket in another coupling element A, the elements being held together by a turnable locking sleeve 13 on the socket and adapted to engage the spigot to lock the elements against axial separating movement, and wherein the locking sleeve turns about an axis 11 eccentric to that of the socket, the spigot has a portion of reduced diameter and defines an annular shoulder 9 and the sleeve has an inwardly directed part 14 which can, upon turning of the sleeve about the eccentric axis, be brought into the reduced portion 8 behind the shoulder, the turning movement of the locking sleeve about the eccentric axis is limited by, and any substantial axial movement of the sleeve is prevented by, a part on the locking sleeve which extends into a peripheral groove 20 formed in the socket. As shown, the leading end 7a of the spigot 7 is received in the bore 3 of the socket element and coacts with a valve plunger 26 loaded by a spring 29 so that in the uncoupled condition of the coupling elements the sleeve 30 carried by the plunger co-operates with a frusto-conical seating 3b; a sealing ring 27 forms a fluid seal between the plunger and bore 3, and radial parts 28 allow a flow of fluid from the socket element to the hollow spigot element. The sleeve 13 is rotatable on the socket against the pressure exerted by a torsion spring 16 and has an inwardly directed annular lip 14 of varying radial extent and defining a circular aperture of a size to receive the spigot 7a and the turning movement of the sleeve is limited to substantially 180 degrees by a pin, extending parallel to a diameter of and passing through the the wall of the sleeve, abutting the bottom 20a of a groove 20 formed in the wall of the socket. A sealing ring 24 is retained in position by a gland 25. In coupling the elements A, B the sleeve 13 is turned against the action of the spring 16 and retained in the unlocked position thereof by engagement of the projecting flange 22 on the socket within the recess 23 of the sleeve, the gland 25 being retracted to allow interengagement between the flange 14 and recess 8 of the spigot. The spigot is then inserted into the socket to open the valve 30 to permit fluid to infiltrate between the abutting portions of the plunger 26 and spigot and act on the ring 24 to move the gland 25 which urges the flange 14 of the sleeve out of engagement with the flange 22 so that the sleeve is thereby free to rotate to the locking position. In uncoupling the elements A, B the sleeve is turned manually to the unlocked position thereof.
