IPC: G01R13/40
Filed: 1969-06-03
Abstract: 1,229,111. Display systems. SINA A.G. 3 June, 1969 [4 June, 1968], No. 28098/69. Heading G4H. A number of numerical values, each related to a different measured quantity, are displayed each in a separate column of lamps, Fig. 1, a lamp being lit to show the deviation of the measured quantity from a predetermined desired value. The apparatus may be applied to a paper mill and indicate the deviations of the thickness of the paper at a number of points from desired correct thickness. The measurements each in the form of a train of pulses, are applied successively to a binary counter A-K, Fig. 3, which has previously been loaded for each measurement with a number representing the desired value. The counter counts backwards so that at the end of the pulse train it may be at zero if the measurement is exactly correct, positive if the measurement is low or contain a negative number in complement form if the measurement is high. In the last case the passage of the counter from all zero to all ones is detected by gates 4 and 7 and a "desired value exceeded" flip-flop consisting of N And gates 9 and 10 is set to give high/low outputs from gates 13, 14. The indicator has eight lamps above zero and eight below. The least significant three digits of the counter are decoded to mark one of eight leads. In addition all the digits above the three least significant are gated at 11 and if any is "1" the tolerance of seven units is exceeded and a signal T is produced. The decoder outputs control the middle 15 lamps and the tolerance exceeded signal T control the top and bottom lamp. The high/ low signals fire one of two thyristors to connect power either to the upper eight lamps or to the zero lamp and the lower eight lamps. One of the nine inputs from the decoder and from gate 16 is marked to fire one of wire thyristors selecting one lamp in the selected group. The lamp remains slit until the same measurement is signalled in the next cycle. Each column of lamps is associated with one stage of a counter which is stepped once by each successive input pulse train to enable the corresponding column of lamps for a display. The deviation values may be printed as well as displayed. A divider may be inserted in the input to the counter to increase the tolerance level, for example by ten times. An alarm may be given by the "tolerance-exceeded" signal.

Abstract: 1,230,823. Sintered aluminium nitride. TOKYO SHIBAURA ELECTRIC CO. Ltd. July 4, 1968 [July 5, 1967, Sept. 11, 1967, Feb. 29, 1968], No.31997/68. Heading C7D. Compacted and sintered aluminium nitride is made by compacting a powder mixture consisting of A1N + Al 2 O 3  + Al + an organic binder, evaporating the binder by heating to below 400‹ C. in nitrogen or an inert atmosphere, nitriding the Al by heating in nitrogen or ammonia at a temperature below the melting point of Al e. g. at 580‹ -620‹ C. and finally sintering in nitrogen or an inert atmosphere at 1600‹ -2200‹ C. The AlN powder should have an average particle size of 0À5-2À5 microns and Al powder less than 2À5 microns. The organic binder may be paraffin, stearic acid or polyvinyl alcohol. The evaporation of the binder and sintering of the compact is preferably effected by packing the compact in a refractory powder such as AlN, BN or SiO 2  and heating in a muffle furnace.

Abstract: 1,256,989. Friction clutches. AISIN SEIKI CO. Ltd. 26 Oct., 1970 [25 Oct., 1969], No. 50714/70. Heading F2C. In a diaphragm-spring engaged friction clutch (10), Fig. 1 (not shown), for a motor vehicle, the clutch driven plate hub 19 splined on a driven shaft 51 frictionally carries an axially slotted sleeve 54 having a flange 62 which abuts the flange 57 on a sleeve 53 to limit the disengaging movement of the driven plate due to a disengaging spring 58 acting between the sleeves. Wear of the friction facings (30) of the clutch plate is compensated for to maintain constant the spacing of the clutch plate from the flywheel 11 in the disengaged position, by the sleeve 54 which, when wear occurs, abuts the shaft bearing 50 on moving the clutch plate into engagement with the flywheel, and is itself moved axially on the hub to a new compensated position.

Abstract: 1,258,076. Pressure vessel closures. LEEDS & BRADFORD BOILER CO. Ltd., and H. M. H. PICKARD. 3 April, 1969 [5 April, 1968], No. 16619/68. Heading F2P. [Also in Division E2]  A horizontally located pressure vessel comprises a door 1 adapted to be swung into open and closed positions about a vertical hinge 2 by one or more pneumatic or hydraulic cylinders 3 which is or are pivoted at one end 4 to the vessel and connected at the other end 7 through pivoted arms 8 and 11 to the door in such a manner that the door is swung through half its movement (open or closed) by travel of a ram rod 6 in one direction in said cylinder and for the remainder of said movement by travel of the ram rod in the opposite direction. The arm 8 is pivoted about a fulcrum 9 which is positioned nearer the arm end connected to the ram rod than the arm end connected to the arm 11, whereby the arms 8 and 11 take up a V configuration in the door closed position and a substantially straight aligned configuration in the door open position. A control valve (not shown), which may be manually or automatically operated, controls the admittance of fluid to said cylinder. In order to reduce the speed of movement of the door at the end of either the closing movement or the opening movement, an air restrictor valve is fitted at the rod end of the cylinder. To make this control more effective, an air valve of a pneumatic system may be actuated by an arcuate camplate fitted to the hinge of the vessel door to recharge the cylinder on the rod side towards each end of the door travel.

Abstract: 1,258,420. Anti-skid control of fluid-pressure brakes. KELSEY-HAYES CO. 31 Jan., 1969 [31 Jan., 1968], No. 5433/69. Headings F2F and F2V. A combined check and bleed valve 76, 100 for anti-skid control of fluid-pressure brakes comprises a valve body 78 located in a relief cylinder 60, which cylinder communicates through a bore 64 with another 62, so that under normal braking conditions brake fluid passes from the cylinder 62 via slots 88, bore 64 and through the notched periphery (95), Fig. 3, not shown, of a ring 91 to the relief cylinder. In addition fluid passes between a bore 90 in the valve body and a bleed valve stem 102, thence through a scalloped inner surface 107 of a flexible seal 79 to the relief cylinder. The seal 79 is generally cup-shaped and engages a head portion 80, groove 83, flange 85 and rearward surface of valve body 78. Under skid-control braking an hydraulic piston 46 is withdrawn from abutment on annular shoulder 86 allowing a spring 84 to urge a portion 87 of the flexible seal to contact a sealing surface 96 on the shoulder thus blocking the main flow of brake fluid to the brake cylinders. Subsequently a spring 106 urges a sealing surface 108 on a cap 105 carried by the bleed valve stem into sealing contact with a boss 103 on the flexible seal 79 thus stopping the secondary flow of brake fluid to the brake cylinders. Pressure relief to a skidding wheel is thus provided by the increase in effective volume of the cylinder 62 due to the partial withdrawal of the piston 46. Upon reapplication of the brakes the bleed valve opens first to permit a gradual increase in braking pressure. The piston is actuated by a diaphragm assembly 42 forming part of a vacuum-suspended servo. Figs. 6, 7 (not shown) give details of a throttling valve assembly 200, controlling the return of the diaphragm to its rest position. Deceleration of a braked wheel is sensed by a reluctance pick-up producing a speed signal which is differentiated in a control module, the resultant signal being applied to a solenoidoperated valve assembly. Fig. 1 (not shown) is a schematic diagram of a skid control system.

There is introduced into a ferrous melt, using carrier gas containing free or bound oxygen but not more than 45% of oxygen by volume, the oxide of metal desired in the product, at a rate and quantity such that a rapid carbon boil is produced but that the production of brown fume is substantially inhibited. The process may be applied to carbon steel, when iron oxide, possibly in the form of millscale, ore or dust from a fume-cleaning plant, is introduced, or may be applied to alloy steels when one or more oxides of iron, nickel, chromium, molybdenum, copper, cobalt or tungsten may be added; in either case a part of the iron oxide may be introduced into the slag bath. Oxide injection may be stopped when the desired carbon content is reached, or may be continued until other impurities have been eliminated followed by recrystallization. A preferred gas is compressed air, but carbon dioxide may also be used.
