Title: Hydrostatic bearings
IPC: F16C32/06
Filed: 1970-08-12
Abstract: 1318066 Beds and frames WERKZEUGMASCHINENFABRIK OERLIKONBUHRLE AG 12 Aug 1970 [21 Aug 1969] 38758/70 Heading B3B [Also in Divisions F2 and G3] A hydrostatic bearing for two relatively moveable parts 1 and 2 e.g. a machine carriage and frame has a bearing member 4 positioned between the parts. A guideway is provided on one of the parts and means are provided for adjusting the position of the other part perpendicularly relative to the guideway. Fluid is supplied under pressure by a pump 31 through a duct 18 to one of the parts. The bearing member has a portion which extends into a recess in the part. Fluid passes through a filter 8 via screw throttles 9 to bearing pads 14. The carriage 1 of a machine is supported in a frame 2 by two bearing members 4 supplied with fluid via a servo valve 30. Deviations in the relative angular alignment of the carriage and frame are detected by elements 25, 26 which operate the servo valve to vary the supply pressure to the two bearings so as to realign the carriage. Deviations in the supply pressure are detected by element 28 which also operates the servo valve to equalise the pressures. The change in the position of the carriage is effected by the changes in fluid pressure not only moving the bearing member 4 but also changing the pressure in the bearing pads 14.

Title: Improvements in destructive hydrogenation
IPC: C10G1/08
Filed: 1929-12-20
Abstract: Catalysts for use in the destructive hydrogenation of carbonaceous materials comprise cobalt or nickel alloyed and/or coated with tin. Suitable alloys comprise cobalt-tin, nickel-tin, iron-nickel-tin, iron-cobalt-tin, nickel-cobalt-tin, and these alloys may be employed in the powdered or massive state and may be coated with tin.  The composition of the alloys should be chosen so that they do not melt under the working conditions, e.g. alloys of cobalt and tin should contain more than 5 per cent of cobalt. Middle oil obtained in a liquid phase destructive hydrogenation is fed in the vapour phase at the rate of 2 kgs. per hour along with hydrogen at 3,5 cubic metres per hour into a vertical reaction vessel packed with rings of a nickel-iron alloy coated with tin, the materials being treated for 2 minutes at 470 DEG  C. and 250 atmospheres.  37,5 per cent of the middle oil is converted into petrol boiling below 200 DEG  C. in one operation rising to 70 per cent by re-cycling the unconverted residues.  Specification 335,215 and 335,216, [both in Class 32, Distilling &c.], are referred to.

Abstract: 1506412 Radar SOC NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION 25 Sept 1975 [27 Sept 1974] 39235/75 Heading H4D In a correlation radar in which the transmission is coded by a cyclically repeating pseudo random binary sequence the received echo is correlated with two representations of the sequence, mutually delayed whereby respective correlation responses of Fig. 2 are produced, the results of the two correlations being differenced to give an equivalent correlation response Fig. 3 exhibiting a sharp (e.g. zero crossing) time/distance label P. The coding and correlating sequences are generated by a shift register run by a variable frequency clock, the clock frequency being controlled by the result of the equivalent correlation response whereby the label P is retroactively acquired and the clock frequency is indicative of distance. In a search mode, a V.C.O. clock HC, Fig. 4 provides clock pulses at 7À1 MHz (141À10<SP>-9</SP> secs.) for driving pseudo random sequence generator register R and a divide by three blocking signal generator 14. Logic gates 10, 11 combine the outputs of R and 14 such that every 3rd 141À10<SP>-9</SP> pulse is fed to a 0/# phase modulator 3 to give a pulse of 2 GHz carrier, Fig. 5 at 0 or IT relative phase. A receiver gate 6 is enabled by the inverse (14<SP>1</SP>) of the blocking signal, and passes echoes of each 0 or # sequence bit to two correlator multipliers C1a and C2a via demodulator 8 and amplifier 16. The multipliers C1a, C2a receive mutually delayed versions of the coding sequences T1 and T I + #T. The correlation results, after removal of Doppler shifts at C1b and C2b are subtracted at S. An integrator 17 supplies a control voltage for the V.C.O. Hc when the output of the substractor S indicates that the target has not been acquired whereby the V.C.O. Hc frequency varies, and a "stop" voltage on acquisition.

Abstract: 1356457 Automatic control of arc welding OSAKA TRANSFORMER CO Ltd 25 Aug 1971 [31 Aug 1970] 39927/71 Heading G3R A D.C. arc welding supply system includes a controlled rectifier triggered by a feedback arrangement including a gain compensating circuit. In the embodiment of Fig.4, a welding electrode 5 is supplied from a 3-phase transformer 1 through thyristors 2, 3, 4 and a choke L. The neutral terminal of the transformer is connected to the workpiece 6 through an output measuring magnetic amplifier M or current transformer which supplies a feedback signal for comparison with a pre-set voltage at a potentiometer Ro. The resulting difference signal is applied to a transistor TR1 enabling a capacitor C1 to charge and turn on a unijunction transistor UJT and thus supply firing pulses to thyristors 2, 3, 4 from a pulse transformer PT. A synchronizing circuit 9 turns on a switching transistor TR2 briefly to discharge capacitor C1 at the beginning of each cycle. A gain compensating circuit, including resistors R6, R7 and an amplifier transistor TR3, operates to provide a parallel path to the base of transistor TR1 so as to reduce the gain of the control circuit when the thyristor firing angle is large. The gain is preferably arranged to be substantially constant for any firing angle. In another embodiment, Fig. 6 (not shown), a feedback signal is compared with a triangular waveform which is distorted, Fig.7B (not shown), in order to achieve gain compensation.
