CENTRE D'ETUDES ET D'APPLICATIONS DES TECHNIQUES DE PRODUCTIONS and MANUFACTURE DE MACHINES DU HAUT-RHIN. 21 Jan., 1966 [22 Jan., 1965], No. 2918/66. Heading B7D. [Also in Division B8] A load-handling truck in a warehouse installation with racks 7 delimiting parallel lanes 8 of width only slightly greater than that of the truck, comprises a chassis 10 supported by three axles 16, 17, 18, the last of which is a driving axle. The front axle 16 has paired wheels 19, 20 of different diameters, the first of rubber to run on the floor 22 and the second of metal to roll on guide rails 21, disposed on the floor 22 of the lanes 8. Drum type brakes are provided on the front axle 16. The central axle 17 has only metal wheels, to roll on the rails 21 while the rear axle 18 has only driven rubber floor wheels and is mounted so as to be able to move relative to the chassis 10. A vertically displaceable horizontal platform 12 is mounted within a turret 11 arranged for rotation about a vertial axis so that loads may be drawn on to or expelled from both sides of the truck by two extendible chains 34 each of which, when retracted, is wound up, and, when extended, is pushed out as a rigid member. The chains 34 are extended at high speed when a button (67), Fig. 13 (not shown), on a control panel, is pushed, until a feeler 64, Fig. 12, contacts a bar 61, Fig. 11, on the end of a receptacle 60. A micro-switch is then automatically tripped and the chains 34 continue to advance at reduced speed. When the feeler 64 is almost completely retracted a new contact trips and the chains 34 are stopped completely as pawls 56 drop into a seating 62. By pressing a button (68) the receptacle is withdrawn at reduced speed. Other buttons, (69), (70) are respectively used to push the load from the platform 12 at reduced speed and to withdraw the chains 34 at high speed. The upper part 37 of the turret 11 is guided by rollers 38 cooperating with rails 39 on the racks 7. The truck carries removable transfer shelving 13 into which a plurality of separate loads of merchandise may be placed for transportation. The turret 11 may be movable relative to the truck. A jack (not shown) or lazy-tongs (not shown) may replace the chains 34.

Abstract: 1366480 Flash welding machine; shearing BRITISH FEDERAL WELDER & MACHINE CO Ltd 15 Dec 1971 [19 Dec 1970 22 Jan 1971] 60398/70 and 2922/71 Headings B3A B3R and B3W A strip line flash welding machine comprises clamps 10-13, Fig. 1(a), for securing the ends of metal strips 14, 15, a shear unit for shearing the ends of metal strips between the clamps, and means 17, 18 for moving the clamps 11, 13, and thereby the strip ends, relative to each other in readiness for welding, said shear unit including a beam 28, Fig. 2, a drive 29 for reciprocating the beam transversely across the strip flow path, and shearing elements 20 mounted adjacent one end of the beam. Metal strips 14, 15 are located and clamped in a shearing position 16 using clamps 10-13, shearing elements 20 are passed through the shearing position, and the clamps and adjacent strip ends moved relative to each other prior to welding the ends together. The shear unit is pivotable about a pin (36), Fig. 3 (not shown), to avoid welding splatter and is energized when the strip ends are in the shearing position and shearing elements 20 move horizontally across the edges 26, 27 of the strip flow path of the welding machine. The elements may comprise two pairs of cutting wheels 31, or a set of rotary upper blades and stationary lower blades or vice versa, or alternatively a guillotine shear, magnets being provided for removing scrap cut-offs from the machine. The elements are mounted on the reciprocable beam 28 in addition to die scrapers 35 for removing welding splatter from main clamp 10, 12 faces. An air blast is provided to remove such splatter from the strips. After the shearing, the main clamps are opened, Fig. 1(c) (not shown), and units 17, 18 are actuated to move auxiliary clamps 11, 13 relative to the main clamps thus causing the strip ends to project an amount controlled by adjustable stops 22. The main clamps are then closed and the strip ends moved using a platen (not shown) which itself moves twice, firstly to abut the strip ends, Fig. 1(e) (not shown), to commence flash welding, and secondly to upset and fuse the heated strip ends. The movements are controlled by two hydraulic piston/cylinder units (40), (41), Fig. 4 (not shown), and their associated stop members (47), (48). Stop members 22, (47), (48) and the hydraulic units are automatically controlled to position the strip ends after the shearing and allow a range of strip widths, the positioning being controlled by a common selector switch. When used in conjunction with a pickling system the welding medium is situated at the beginning of the line and four rotating laminated sanding wheels 50, coated with silicon carbide, are used to remove scale from the strip. The number and position of the wheels, which are adjustable, depends on machine design and the method of current supply through the clamps. Alternatively, solid or flexible grinding wheels, or sanding discs or belts, may be used. Also, shot or sand blasting nozzles attached to the beam 28 enable removal of surface coatings on the strip surfaces.

Moulding phonograph records. - In presses employing book-form moulds of which the mould plates are furnished respectively with a fixed and sliding central pin, the sliding pin engages during the pressing operation with its end away from the mould face against a spring-pressed plunger in one of the press platens. The spring is so selected as to resist sliding movement of the pin until practically all the record material has been squeezed out from between the ends of the pins. As shown, the lower mould 1 is furnished with a slidable central pin 4 held frictionally by a spring 6 &c. The upper mould 17 carries a pin 18 adapted to depress the pin 4 against the action of a plunger 12 located centrally of the press ram 8 and forced upwardly by a spring 13. In use, with the moulds out of the press and open, the sliding pin 4 is pressed upwardly beyond the matrix sufficiently to locate the lower record label over which is laid the'record material. The upper label is located over the pin 4 or over the pin 18 and the moulds are closed and inserted into the press. As the ram 8 rises, record material is pressed outwards and the pin 18 depresses the pin 4 against the action of the spring 13 and finally enters the aperture 3 housing the pin 4. The pin 4 is restored by engagement with a stationary projection when the mould is removed from the press and opened.

Abstract: 687,540. Automatic volume control. STANDARD TELEPHONES & CABLES, Ltd. Feb. 16, 1951, No. 3815/51. Class 40 (iv). [Also in Group XL (c)] The invention relates to communication systems in which the gain of a repeater is controlled by a pilot wave transmitted with the signals. Such a system comprises an amplifier having a positive feed-back path between output and input to cause the amplifier to oscillate and a rectified negative feed-back path between the said input and output for the oscillation frequency, the pilot being applied to the said input for amplification extracted from the said output, rectified and then applied to the input to control the amplitude of oscilla. tion. The oscillation may then be used to operate a thermistor controlling the gain of a repeater. The anode circuit of the valve shown is tuned to 2000 c/s. by a circuit 5, 7 and positive feed-back to cause oscillation at this frequency is derived from this circuit and applied to the cathode. A further circuit 6, 16 tuned to this frequency feeds part of the output to. a voltage doubler rectifier 10, 11 and applies the rectified voltage in a negative sense to the control grid. The pilot, which has a frequency of 60 kc/s. and is also applied to the control grid, is amplified in the valve, selected by an anode tuned circuit 4, 21 and applied to a voltage doubler rectifier 22, 23, the rectified output being applied to the control grid to vary the oscillation output from circuit 5 in dependence upon the pilot amplitude.

Abstract: 370,100. Electromagnetic switches. IGRANIC ELECTRIC CO., Ltd., 147, Queen Victoria Street, London, and MACKLEY, A. H., 15, Waterloo Road, Bedford. Feb. 6, 1931, No. 3863. [Class 38 (v).] An arrangement depending on electrical induction is used to ensure that a discharge resistance which has been connected across an electromagnet winding when the magnet circuit is broken remains so connected for a transient period after this circuit is broken. In the form shown, the electromagnet winding m is energized by lowering the switch 9 to the lower pair of contacts which closes contacts 1, 3, 4, and is de-energized by raising the switch 9, which then energizes the winding 7 of the contactor c<2>. The closing of the contact 2 of the contactor c<2>, besides shunting the magnet by the resistance r, de-energizes the operating coil 10 of contacts 1, 3, 4 by opening the contacts 5, and shunts it by the resistance r<1>. Although the contacts 1, 3, 4 have now opened, thus de-energizing the coil 7, the opening of the contactor c<2> is delayed by the shortcircuited winding 8, which may consist of a number. of copper discs.

[Also in Group XXIV] In order to impart to a body A such as a mixing container a wobbling movement combined with a rotation on its own axis, the body A is carried by two rings 6 pivoted in forks 4, 5, themselves pivoted to spaced parallel auxiliary shafts 2, 3 which rotate at the same speed in opposite directions, and according to the invention a non-uniform rotation is obtained by driving one or both of the auxiliary shafts 2, 3 through respective universal joints 2a, 3a on shafts 8, 9 which are inclined at 45 degrees to the shafts 2, 3, the angle (90 degrees as shown) between the two pivot axes (2c, 2d) on each auxiliary shaft being complementary to the angle (zero as shown) between the plane containing the two auxiliary shafts (2, 3), and the plane containing the universally jointed shafts (2, 7). The shaft 8 is coupled by bevel gearing to the shaft 7 which is driven by a motor 12. In a modification, Fig. 2 (not shown), the auxiliary shafts are coupled through universal joints to respective shafts which while being inclined at 45 degrees to the auxiliary shafts are parallel to each other so that the angle between the planes referred to above is 90 degrees and consequently the complementary angle between the two pivot axes is zero (i.e. the axes are parallel). In this modification one of the shafts coupled to the universal joints is driven through belt gearing while the other is not driven but carries a flywheel. Alternatively the second universal joint and flywheel may be omitted. Specification 548,355 is referred to.
