Abstract: 1,258,028. Irradiation apparatus. A. E. ATOVMIAN, V. I. GORDON, I. A. DAVYDOVA, A. B. LITVAN and B. P. MAZANKO. 16 May, 1970, No. 23847/70. Heading H5R. A diaphragm for limiting a beam of ionizing radiation-e.g. gamma rays-includes a plurality of shielding blocks 2 to 13 arranged in pairs, one pair below another, all the blocks being movable, to and fro, only in a single common direction to alter the diaphragm aperture size. As shown, all the blocks are movable along guide rails 51 and 52, and have aperture defining faces making an angle of 45 degrees with the rails. The twelve blocks, which may be of tungsten, are coupled three each to the two ends of arms 21 and 24 rotatable by shafts 17 and 18, such that rotation of shaft 17 clockwise pulls blocks 5, 9 and 13 to the left and pushes blocks 4, 8 and 12 to the right, while rotation of shaft 18 anti-clockwise pulls blocks 2, 6 and 10 to the right and pushes blocks 3, 7 and 11 to the left, to reduce the size of the aperture without change of shape.

Abstract: 1,258,973. Desalination of sea water by freezing. MITSUI SHIPBUILDING & ENG. CO. Ltd. 24 June, 1969 [29 June, 1968], No. 31757/69. Heading C1C. Fresh water is produced from sea water by spraying, e.g. through nozzles 32, a liquid refrigerant, e.g. butane or propane, on to one side of a run of a metallic belt 2, spraying sea water, e.g. through nozzles 27, on to the other side of the run of the conveyer to form ice, spraying the ice with fresh water, e.g. from nozzles 46, to remove brine and collecting and melting the ice after it separates from the conveyer. As shown, the sea water is pumped from a tank 20 to the conveyer 2 via precoolers 24, 25 which are respectively fed with cold fresh water from a melting tank 4 and brine from a freezing chamber 1. Vaporized refrigerant is removed from chamber 1 by conduits 7 and 9 and a compressor 8 and liquefied by injection into the melting ice in tank 4 whence it is recycled to nozzles 32. Fresh water from tank 4 is collected in a tank 44 after passage through a refrigerant vapour precooler 14. Vaporized refrigerant is drawn from tank 4 and returned thereto after liquefication following passage through precooler 14, a further precooler 15 fed with cold brine from chamber 1, and a vapour separator 17. Brine leaves the apparatus via conduit 38.

Abstract: 1289214 Linear feed control of a rotary tool RUSTON-BUCYRUS Ltd 5 Aug 1970 [ 3 Sept 1969] 37706/70 Heading G1N Apparatus controlling a drill 5 comprises a rotary drive motor 8 driven by a Ward-Leonard set 9, 10 in which a resistor 35 produces signals indicative of motor torque to a comparator circuit 55, 57 which also receives from pressure transducers 22, 23 signals indicative of the linear driving force applied to the drill by an hydraulic linear drive motor 11, the comparator producing a signal to servo amplifier 51 to vary the speed of the linear drive motor from a pre-set value when the torque signal at terminal 58 of the comparator exceeds the linear force feedback signal at the terminal 59 of the comparator. The speed of the linear driving motor is sensed by a tacho-generator 26 feeding the servo amplifier, a reference linear speed signal being set by potentiometer 45 whilst the rotary speed is set by potentiometer 41: The required relationship between torque and linear feed pressure for a given terrain to be drilled is set by gain control potentiometers 71, 81. Each pressure transducer comprises a strain gauge on a diaphragm which gauge is connected in a bridge circuit (not shown). A vibration sensor 92 acts via relays 93, 96, 98 to reduce linear and rotary speeds in the event of excessive drill vibration. In an alternative embodiment, Fig. 2 (not shown) clamping diodes (109, 113) are connected to receive the linear motor speed feedback signal from the tacho and to receive the linear force signal and are connected to the linear motor speed control circuit to prevent reversal of the direction of the linear motor, when abnormal operating conditions prevail.

Abstract: 1312784 Measuring angles; measuring refractive index electrically BELLINGHAM & STANLEY Ltd 15 Dec 1970 [19 Dec 1969] 62018/69 Headings G1J G1N and G1X [Also in Divisions G2 and G4] A refractometer includes an arrangement for producing an output proportional to the refractive index. In one form Fig. 4 a prism 6 is illuminated at grazing incidence and a telescope mounted on pivoted link 11 aligned at the critical angle, the length of a telescopic link 17, 18 then being directly proportional to the sine of the critical angle and therefore to the refractive index in a modification Fig.6, the telescope is stationary and the prism rotated, the length of telescopic link 29, 30 being proportional to the refractive index. The length of the telescopic link may be read by a pointer and scale Figs. 4, 6, a linear potentiometric transducer Fig. 11 (not shown), in association with a recorder or a digital voltmeter, an optical grating the lines of which are counted photo-electrically, or by an optical grating cooperating with a matching segment to produce a fringe pattern counted photo-electrically Fig.8. The critical angle may be detected by means of a cross wire or a photo-electric device and a servocontrolled drive may be produced for automatically aligning the telescope to the critical angle. In the automatic refractometer of Fig. 8, a motor 47 drives a pin 48 engaging slot 49 in link 42 and oscillates the prism through an angular range. As the critical angle is passed through, this is detected by photo-cell 63 which prevents further counting of the fringes produced by grating 52 so that the reading representing the refractive index is maintained in the counter. A second scale may be provided to indicate a function of the refractive index such as sugar concentration. Alternative by the output of a potentiometric transducer representing the refractive index may be processed electronically to produce a signal representing the sugar concentration Fig. 11 (not shown). The arrangement of links may be modified so that the devices of figs. 4 and 6 produce an output proportional to the cosine in addition to or instead of that proportional to the sine.

Abstract: 1322505 Yarn treating apparatus COURTAULDS Ltd 18 Nov 1970 [19 Nov 1969] 56628/69 Heading D1L Apparatus for applying a relaxation treatment to a textile yarn comprises a stainless steel lattice 1 supported for movement around a closed path by rollers 2. A stationary coiling head 3 delivers a yarn 12 from a package 13 via yarn guides 14 onto the upper run 4 of the lattice which is driven at a constant speed in the direction shown by the arrows A. The lattice 1 then advances towards a treatment vessel 16, 17 which is connected to a steam supply or to a vacuum reservoir thus forming a substantially sealed chamber. Intermediate to the coiling head 3 and the treatment vessel 16, 17 is a first storage device comprising a pair of freely rotatable rollers 30, mounted with their axes parallel and an endless belt loop 31, which can move in a direction normal to the plane of the lattice between the rollers 30, deflecting the lattice into a U-shaped loop. The second storage device comprises a pair of parallel rollers 40, 41 and an endless belt loop 42 supported by rollers 43 and two frame members 44, the latter being slidably mounted to allow the belt loop 42 to deflect the lattice into a second U-shaped loop, between the rollers 40, 41. The roller 41 is freely rotatably mounted but the roller 40 is drivable by a motor M through a chain 45 and sprockets 46, 47. During the treatment step the belt loop 31 descends, storing the still-advancing yarn covered lattice as a loop of steadily increasing size, while the belt loop 42 descends, paying out the lattice from its previously stored loop. The yarn after treatment may be cooled by drawing air through it by means of a suction head before it is wound onto a spool.

Alternatively, the seondaries may be on a common core having a single primary winding. The load is capacitive and current limiting resistors may be connected in series with the load or with each transistor string. Where the transistor strings are arranged in bridge configuration, diagonally opposite pairs may conduct together and an intermediate condition provided in which adjacent pairs conduct. Different supply voltages may be applied to each series pair so that the output wave is assymetrical. Charge storage delays are reduced as the series turning on switches of the adjacent series. The circuit is used to supply a half wave voltage to a Z-cut KD*P crystal in the digital electro-optical deflectors of a read-only randomaccess holographic memory. The two modulators of the memory may also use Z-cut KD*P crystals connected optically in series but electrically in parallel.
