IPC: B65G57/04
Abstract: 1,052,641. Stacking-machines; suction lifting heads. BASON & SONS Ltd. Sept. 23, 1965 [July 4, 1964]. No. 27669/64. Headings B8C and B8H. A device for upturning a layer of articles so that they may be stacked with certain faces in contact, e.g. bringing decorative faces of bricks into contact to prevent marking in the kiln, comprises an invertable head having suction grippers on opposed faces and movable vertically to pick up and lower articles and laterally to clear an assembly table during inverting of the head. The device operates in conjunction with the stacking machine described in Specification 1,016,012. The head 33 is rotatable about trunnions 39 pivoted in arms on an elevator 32, itself mounted on a carriage 15 movable along rails 13. The head comprises adjustable parallel bars 40 on both faces, Figs. 4-7 (not shown), slotted at 41 to receive suction grippers 43, each for lifting a single brick. Elements 42 on the grippers slide into enlargements 40a of the slots and are retained, resiliently mounted, by springs 44. In operation, a layer of bricks 58 on a platform 57 is gripped by the head which rises and is withdrawn along the rails 13. The head then rotates 180 degrees and returns to above the platform. Suction is transferred to the lower grippers leaving the layer to be picked up by the gripper head 60 of the stacker while a fresh layer is engaged on the platform. Alternate layers are picked off the platform direct by the head 60 while the inverting head is withdrawn.

Abstract: 1,052,811. Trailer brakes. TOLEDO STAMPING & MANUFACTURING CO. Jan.16, 1964, No.2047/64. Headings F2E and F2F. A hitch for connecting a trailer to a towing vehicle and for actuating the brakes to the trailer comprises a front hitch member 16 for connection to the towing vehicle at 20 linked at 24 with a rear hitch member 18 so as to allow relative longitudinal movement, a brake actuator 42 mounted on the hitch member 16 co-operating with brake-actuating means 30 on the hitch member 18 and a shock absorber 82 connecting the hitch member 16 and the actuator 42 so as to resist sudden movement of the latter in a direction to actuate the brakes when the hitch members move suddenly towards each other. The links 24 are pivoted on the hitch members at 26. The actuating means is a cylinder 30 of which the piston rod 34 has a central flange 38 and is supported on a guide 36 on the member 18. A spring 40 prevents actuation of the brakes when the trailer is towed down a slight slope. The brakes (not shown) are self-actuating requiring about one fifth the force to brake effectively in the forward direction as compared with the opposite direction so that the trailer can be backed by the towing vehicle. The actuator 42 is pivoted at 48 to ears 44 on the hitch member 16 and includes a yoke 50 which engages the flange 38 to apply the brakes when the trailer overtakes the towing vehicle. A leg 52 of the actuator protrudes through an opening 54 in the bottom wall 56 of the member 16 to press on a plate 58 which is urged against the wall 56 by a spring 62 which is stronger than the spring 40. Upon acceleration of the towing vehicle the hitch members tend to separate so that the actuator 42 turns counter clockwise until stopped against a bar 72. Further relative movement of the hitch members will continue as the rod 80 moves out of the shock absorber; backward and forward movement of the members being limited by a stop bar 68 in a notch 80. If the speed of the towing vehicle is decreased slowly the rod 86 will move into the shock absorber with little resistance so that the actuator 42, supported against a stop 72 as in Fig. 1 by the opening 62, will gradually apply the brakes. If, however, the brakes of the towing vehicle are applied suddenly, movement of the rod 86 into the shock absorber is resisted so that the actuator rotates clockwise and compresses the spring so that further relative movement of the hitch members is then necessary to apply the brakes. Subsequent entry of the rod into the shock absorber allows the spring 62 to rotate the actuator 62 anti-clockwise and add its force to apply the brakes more strongly still. As application of the brakes is dependent, in the long run, on the strength of the spring 64, so that the force with which they are applied is largely independent of the load carried in the trailer. Figs. 5 and 6 (not shown) illustrate a version of the hitch which is suitable for heavier vehicles than that shown in Fig. 1.

Abstract: 1,226,676. Programmed control of machines. GENERAL ELECTRIC CO. July 17, 1968 (Aug. 10, 1967], No.34137/68. Heading G3N. A numerical control system comprises a command signal generator, responsive to controlling input signals, for generating a command signal for a servo-control loop positioning a device, an absolute position register, for registering the desired position of the device, and a position tracking device for adjusting the position register and the command signal generator when the servoloop is interrupted. As shown, command signals are applied to a terminal 28 and fed to an absolute position register 12, indicating desired machine position, and a phase counter 10, providing a phase-controlled output waveform to an input of a discriminator 18 forming the comparison element of a control loop 35. The other input of the discriminator is supplied from a wave shaper 16 with a squarewave having a phase dependent upon the position of a machine 22 as sensed by a feedback transducer 24 comprising a resolver supplied with a sinusoidal waveform from a source 26. The discriminator detects the phase difference between the inputs and through a servo 20 moves the machine 22 towards the commanded position. The phase relationship between the inputs to the discriminator is also sensed by an update whenever the control loop 35 is interrupted. The output signal on lead 36 updates the absolute position register 12 whereby it always provides a correct numerical indication of the machine position. The machine control loop is interrupted by a switch not shown, to permit manual positioning which, it is stated, can be recorded to provide a programme for future automatic operation.

Abstract: 1,228,383. Bulk negative resistance effect oscillators. HITACHI Ltd. 2 July, 1968 [14 July, 1967], No. 31495/68. Heading H1K. [Also in Division H3] A bulk effect device with a predetermined doping and active region length is operated at such a voltage that sufficient carriers are injected into the region from the electrodes as to cause instability in the space charge limiting current and thus give rise to oscillations at a frequency determined by a resonator to which the device is coupled. The minimum operating mean field in the device is 15 kV./cm. where an n-type gallium arsenide active region with a doping of 10<SP>15</SP>/cm.<SP>3</SP> and length of 10<SP>-4</SP> cm. is used. The amplitude of oscillations increases with an increase of the product nl for a given operating field. Several devices may be connected in series and convenient configurations for this are shown in Figs. 6 and 7. The Fig. 6 structure consists of layers alternately of metal 1 and n-type gallium arsenide 2. Alternatively layers 1 are of heavily doped gallium arsenide, in which case the structure may be produced by epitaxial growth. In Fig. 7 the semi-conductor 2 is deposited on and in the interstices between metal strips 1 and 1c divided from an overall metal layer on insulating substrate 4 by electron beam or photoresist and etching techniques. The use of other semi-conductor materials such as gallium or indium antimonide, indium phosphide, gallium arseno-phosphide, zinc oxide, and cadmium sulphide or telluride is contemplated.

Abstract: 1,232,045. Welding by fusion. KERNFORSCHUNG FUR G.m.b.H. 19 July, 1968 [5 April, 1968], No. 34479/68. Heading B3R. In order to prevent formation of intermetallic phases or brittle mixed crystals in a weld seam between workpieces of different metals, a metal foil is interposed in the butt joint between the workpieces, and a continuous or pulsed charge carrier beam is used to weld the sides of the foil to the respective workpieces to form two welds separated by an unmelted zone of the foil. Ferrous alloys, e.g. 18 Cr, 8 Ni, steel, or iron itself may be welded to non- ferrous metals, e.g., titanium or zirconium using a vanadium foil. Where the nickel content of the ferrous alloy exceeds 25%, an iron foil is interposed between the ferrous alloy and the vanadium foil. The high nickel ferrous alloy could be replaced by a nickel based alloy such as " Inconel " (Trade Mark). The beam may be pulsed and deflected longitudinally of the foil during the pulses and transversely of the foil during the pulse intervals, the work being fed continuously. In this way the foil may be joined to each workpieee by a continuous or intermittent weld. Workpieces 1, 2 with interposed foils 3, 4 are joined by welds 6, 8, 10 to 14 formed by a beam pulsed and deflected laterally. By altering the workpiece feed rate or the pulse deflection rates, continuous welds may be formed.

Abstract: 1,238,565. Irradiation apparatus. COMMISSARIAT A L'ENERGIE ATOMIQUE. 9 Oct., 1969 [23 Oct., 1968], No. 49587/69. Heading H5R. In the irradiation of objects moved past a panel of radio-active sources held in a flat frame, a mask of radiation absorbent material having openings therethrough is placed immediately in front of the panel, the openings having a cross-section which increases from the source side to the object side, whereby greater uniformity of dose throughout the depth of the object is achieved. As shown, the radio-active sources are rods 2 mounted on a frame 3 interposed between two masks 4 each of which is formed by an array of elements 6 of absorbent material, past which the packages 7 for irradiation are moved. It is shown that for points in the irradiated object at increasing distances from the source the decrease in radiation intensity is partially compensated by an increased solid angle of irradiation (Fig. 3, not shown), and that non-uniformity of radiation dose for points in the object lying in a plane parallel to the source panel, but spaced in a direction transverse to the axes of the source rods, is similarly decreased by the presence of the mask (Fig. 4, not shown). To further reduce dose non- uniformity, the source rods and the mask may be inclined at a small angle to the direction of movement of the object 7 (Fig. 5, not shown). In an alternative embodiment, in which the source is composed of an array of point sources, the mask is in the form of an absorbing member having an array of truncated pyramidal or conical apertures aligned with the point sources (Figs. 6, 7 and 8, not shown). Reference is made to the use of the apparatus for irradiating a liquid.
