Patent GB-1267026-A (GB)
IPC: G01R23/02
Filed: 1970-08-18
Abstract: 1,267,026. Pulse circuits. MULLARD Ltd. 18 Aug., 1970, No. 39698/70. Heading H3T. [Also in Division G4] In a system for determining the repetition interval of pulses in each of one or more trains by detecting triple coincidence between the pulses and themselves delayed by a predetermined time and also by twice the predetermined time in tapped storage delay means, subsequent false indications of sub-harmonics of the true intervals are prevented by cancelling the pulses present in the storage delay means when the interval has been determined. As shown, pulses in the input train IP are shaped at PS1, PS2, and applied to two shift registers SR1, SR2 one of which is clocked at half the frequency of the other. Corresponding stages of each register are connected as inputs to AND gates A (one for each stage), a third input to which is the input pulse train (after shaping). Thus, if the input has pulses with an interval of t and/or T those AND gates are enabled which are associated with the stages which are reached after a delay of t and 2t and/or T and 2T. When an AND is enabled an associated bistable circuit is set to give an output at Q, the Q outputs being connected to further AND gates RA having other inputs connected to a third shift register SR3 which is clocked at a higher frequency g than the others. These AND gates are connected by a common line to a readout device DR (such as a CRT) which is scanned at the clock frequency g so that the display indicates which pulse intervals are present in the incoming pulse train (providing at least three consecutive pulses having the relevant interval are present). To prevent spurious indications at, for example, intervals 2t, 4t the bi-stable circuits are reset immediately after readout by the subsequent stage in the register SR3 and the reset outputs Q, after differentiation at PC, cancel the pulses in the corresponding stages of SR1, SR2 (which have not yet stepped on). Circuit units such as those shown enclosed by the dotted line may be in integrated form. Instead of separate shift registers SR1, SR2 a single register may be used with connections taken from appropriate stages to produce the delays t and 2t &c., and the range of time intervals which may be measured may be extended by halving the clock rate at one or more points along the registers. This is effective because a rate which is necessary for short time intervals is unnecessarily high for longer intervals.

IPC: C01B7/03
Filed: 1969-03-31
Abstract: 1309744 Metal oxides from chloride hydrates WOODALL-DUCKHAM Ltd 30 June 1970 [31 March 1969] 16781/69 Heading C1A A metal oxide and HCl are produced by decomposing particles of a metal chloride hydrate, separating the oxide from the HCl-containing gases, absorbing the HCl in an HCl solution to give a superazeotropic solution, distilling this solution to recover dry gaseous HC1, and recycling the remaining solution to the absorption stage. The chloride hydrate may be obtained by spray-drying a chloride solution, such that a lower hydrate is formed. The absorption may be carried out at atmospheric pressure in a cooled absorber to which gases and acid are fed at 100‹ C., to give a solution at 30‹ C. containing 36% HCl. The gases may initially be quenched to 100‹ C. by scrubbing with HCl. A further absorption stage may be provided using cold 15% HCl which is recirculated through a heat exchanger with make-up water. The distillation may be effected at atmospheric pressure to give an azeotropic solution (21% HCl) which may be heat exchanged with the 36% soln. Acid may be bled off from both absorption circuits, mixed with some product MgO, and fed to the spray drier. The metal may be Mg, Fe<SP>2+</SP>, Fe<SP>3+</SP>, Al, Ni, Co or Mn.

Abstract: 1328668 Calculating apparatus A A T SHUTE 23 Dec 1970 61166/70 Heading G4B Apparatus which may be used for calculating the latitude and local time of a location from a single observation of a celestial body comprises a horizontal annular surface 3, a first semiannular member 5 lying in a vertical plane and extending between diametrically opposite points on the annulus 3, a disc 13 mounted for rotation about an axis that coincides with a diameter of the disc and lies in, and is rotatably adjustable within a second vertical plane at right angles to the first vertical plane, and a second vertically disposed semi-annular member 7 extending between diametrically opposite points on the horizontal annulus 3 and rotatable about a vertical axis passing through the centre of the annulus. The horizontal annulus 3 is marked with a scale from 0-360 degrees and with points of the compass, the fixed semi-annulus 5 is provided with a "time" scale, the rotatable semi-annulus 7 has a scale covering 0-90. degrees on either side of the highest point on its inner periphery, and the disc 13 is marked with a "latitude" scale about its periphery. In the embodiment described the ends of the semiannulus 7 are movably located on a circular rail 6, and the pivoting axis of the disc 13 is adjustable by means of a rack 8 and drive pinion 19. In use the altitude and direction of say, the sun, is observed, and the declination of the sun at the time of the observation is obtained from standard tables. The axis of the disc 13 is then set to an angle to the horizontal corresponding to the noted declination, and the semi-annulus 7 is rotated until it lies in the direction of the sun at the time of the observation. The disc 13 is then pivoted until its edge registers with the point on the scale of the semi-annulus 7 corresponding to the observed altitude of the sun. The intersecting point on the scale of the disc 13 is the latitude of the location and the intersection of the disc with the "time" scale on the semi-annulus 5 gives the local time of the location, from which the longitude of the location may be obtained by comparison with G.M.T.

Title: Extrusion of metals
IPC: B21C25/00
Filed: 1969-11-27
Abstract: 1335818 Extruding FORMALLOY Ltd 23 Nov 1970 [27 Nov 1969] 57972/69 Heading B3P A metal extrusion press for extruding tubes comprises a plunger 27 with a mandrel 28 which co-operates with the extrusion die 23 at the end of the extrusion stroke to produce a reduced thickness region 25 between the extruded tube 18 and the discard 24 which can be separated by an axial pull on the tube. The pull can be applied continuously during extrusion and increased to effect the separation. A gripper jaw set 56, Fig. 10, is pneumatically operated to grip the end of the tube 18. The extruded tube displaces a crosshead 55 on which the jaws are pivoted and a rack 57 actuates a limit switch 58 to operate a piston-cylinder unit 59, 60 for the jaws. A carriage 67 is driven by a rack and pinion 68 to pull the crosshead 55 by engagement of the racks 57 and fixed pinions 79. A constant tension is applied to the tube by a pneumatic pistoncylinder unit 74. At the end of the extrusion a second pneumatic piston-cylinder unit 75 is actuated to rotate the pinions 76 by a pawl 76 and ratchet wheel 77. This causes the additional pull of the tube to separate it from the discard. In an alternative embodiment collet jaws 82 are used and operated by an outer sleeve 84 moved axially by an hydraulic piston-cylinder unit 85, 86. The jaws are moved to pull the tube for separation by an outer hydraulic piston-cylinder unit 87, 88. The mandrel 28, Figs. 2 and 6, is connected to the plunger 27 by a tie bolt 35 with internal cooling air passages. The extruded tube may also be cooled by a water jacket 36. The discard is engaged in a dovetail slot in the plunger so that it can be removed from the die and is stripped from the plunger by a ring of segments 43. The extrusion is preferably cold but the billet may be initially heated to about 200‹ C. or cooled so that during extrusion its temperature does not exceed the recrystallization temperature of the metal, e.g. aluminium or aluminium alloy. Thus the metal is work-hardened during extrusion. The plunger speed may be 10-90 inches per minute with an extrusion ratio between 25 : 1 and 60 : 1. The exit speed from the die will be 250-5400 inches per minute. The formed tube will be 20-100 feet long.

Abstract: 1347730 Valves CIRCLE SEAL CORP 22 Sept 1971 44138/71 Heading F2V [Also in Division G3] In a pilot-operated pressure relief valve 10, rise in the pressure at the inlet 12 displaces a stem 36 to the left, as seen in the drawing, with the result that a pilot ball valve 18 is unseated. In consequence, the pressure within a chamber 70, to which chamber the inlet pressure leaks along the stem 36, is vented to atmosphere along a path 21, 62, 60 and so the main valve member 25 is moved away from its seat 27 by the force of the inlet pressure acting thereon. The seat 27 is carried by a sleeve member 28 having a limited degree of movement to facilitate proper seating thereon of the main valve member 25. Leakage along the stem 36 to the chamber 70 takes place past a V-shaped resilient ring 41 whose limbs 42, 43 are biased by a spring ring 44 into engagement with, respectively, the main valve member 25 and the stem 36. The inner limb 42 acts as a scraper during relative movement of the stem 36 and the main valve member 25 so ensuring that the leakage path 35 between the stem and member remains unobstructed. Outer ring seals 67 disposed in two recesses 66 of the valve housing parts 11, 55, serve to seal the valve relative to a manifold to which the valve may be secured by a screw thread 69.
