Title: Automatic transfer system for packages
IPC: B65G1/06
Filed: 1973-11-20
Abstract: 1440680 Transfer of packages CONSTRUCTIONS MILLS K 20 Nov 1973 [14 Dec 1972 19 Jan 1973] 53855/73 Heading A4T  A system for transfer of packages e.g. in a dispensing cabinet comprises at least one substantially horizontal chute 1 having pick-up rails (4), Fig.4 (not shown), for a D.C. supply flanked by support means (3) for packages and a carriage on the chute 1 arranged to be driven by power picked up from the rails (4). Means 10 on the carriage is retractable as the carriage moves forward into a position under the package, and is then liftable with support rollers 14, 16 on the carriage under the package unless the means 10 encounters a further package adjacent the first, and drive means 9 is provided which, on such lifting of the support rollers 14, 16, acts to move the carriage and package until the means 10 is retracted by engagement with a further package so that packages may be moved to adjacent positions. The drive means 9 consists of a driven roller, and on advancing the carriage so that the means 10 and a feeler roller 13 engage below the package, support members 11  pivot against spring means 18 so that the carriage may enter below the package without lifting it. The rollers 14, 16, supported on the members 11  and arms 17 biased by spring means 19, thus become located below the package, the combined effect of the springs 18, 19 being sufficient to lift it from the support means (3), provided that the means 10 has not become engaged below an adjacent package. The package may then be moved on the carriage to a position adjacent a further package, the roller 14 being driven through a coupling roller 15 in the same direction as the means 9 to prevent inertia from causing the package to slip backwards as it is transported. At this position, the means 10 is pivoted downwards to release the package being transferred, and the carriage may then be retracted, an electromagnetically operated locking arrangement Fig.3 (not shown), being provided to hold the support members 11 in the downward position during withdrawal, while an axle 15a of the roller 15 rises in arcuate slots 15b to disconnect the drive. Electric circuitry, Figs.5-9 (not shown), is provided for controlling transfer to and from the chute 1 in accordance with the sensed positions of the packages concerned.

Abstract: 1451058 Making fibre-reinforced wire; drawing G RAU 3 Dec 1973 [6 Dec 1972] 55897/73 Headings B3A and B3P In a method of marking a fibre-reinforced metallic material, an advancing bundle of metal-sheathed wires is jacketed in an originally non-tubular metallic jacketing material, and the jacketed bundle is deformed plastically to reduce its cross-sectional area to convert the wires to fibres and to bond the sheath material into a homogeneous matrix for the fibres. Sheathed wires 4, e.g. silver-sheathed nickel wires, are wrapped in tools 2, 3 with strip 1, e.g. of soft iron, reduced in tools 5, 6, 7, and possibly heat-treated. At least part of the jacketing material may then be removed, e.g. by peeling or grinding, or by chemical or electrochemical means. The jacketing material may be the same as the wire sheathing, and the jacket may be formed by at least one layer of helical winding. The sheathed wires may be pleated, and the resulting reinforced strands may be used as the wires in a similar process. The interior surface of the jacketing material and the sheaths may be cleaned to a metallic bright condition before plastic deformation. Lubricant may be applied to the outer surface of the jacketing material, before plastic deformation, e.g. by wetting, by electrodeposition, by vapourdeposition or by smearing.

Abstract: 1,224,700. Compression moulding powders under reduced pressure. SHIONOGI & CO. Ltd. 18 Nov., 1969 [18 Nov., 1968], No. 56509/69. Heading B5A. In a rotary table compression moulding machine wherein powder is compressed in a die between upper and lower opposing punches, the powder is subjected to reduced air pressure before and during the compression. The punches are carried by a rotational structure 1 rotating on a stationary frame. The upper punch 6 is located in guide sleeve 2 which in turn is located in a receptacle 11. The lower end 21 of guide sleeve 2 carries a flexible rubber boot 7 which contacts a matrix 3 having a die cavity when the sleeve 2 is lowered. Holes 24 in sleeve 2 connect the upper punch 6 with cavity 17 in receptacle 11, and thence to pipe-line 14. The lower punch is mounted in slide guide portion 13 and passes through recess 8 which is connected to pipelines 15 and 16. The air pressure around the punches and in the die cavity is controlled by pressureregulating means 5 and 9 which are fixedly mounted on the stationary frame and connected to a source of reduced air pressure. The pressing cycle commences with the upper punch 6 and guide sleeve 2 raised and a flow of air through recess 8 removing any powder remaining from the previous process, this flow continuing while the lower punch 4 is lowered and the cavity filled. The air flow is then stopped, lower punch 4 is raised slightly and the surplus powder scraped away. The lower punch is again lowered and the pressure inside chamber 8 is reduced by extraction of air through lines 15 and 16. Sleeve 2 is lowered into contact with matrix 3, air inside the sleeve is removed through pipeline 14 and the upper punch is forced downwards to compress the powder. After compressing, both air chambers are opened to the atmosphere, the upper punch is raised and the tablet formed is raised on the lower punch and then swept away by a deflector. The reduced air pressure is preferably less than 200 mm. Hg absolute and the spaces between the moving parts are sealed by 0-rings 40. The punches and guide sleeve are operated by conventional guide rails (not shown).

The tongues are uniformly spaced around the sleeve parts, the tongues 55 of the sleeve part 53 engaging in the gaps 58 between the tongues 56 of the other part 54 and vice versa. The edges of the tongues are shaped to provide co-operating grooves and ribs to effect the positive engagement. A ring 67 is preferably provided within one of the sleeve parts, e.g. 53, to maintain the disposition of the tongues. The tongues may also be provided with longitudinally extending ribs 61, 62, 63, 64 on which the yarn rests to present a minimum surface contact between the yarn and the sleeve. The axially inner ends of the tongues may be bevelled as at 65, 66 to facilitate sliding beneath the yarn layers. In use, the sleeve is fully extended and maintained in this position by adhesive, a co-operating rib and groove (72, 73) or a frangible integral contact, and is then wound with yarn, e.g. crimped synthetic polymer yarn. The sleeves are then loaded in a treatment chamber with one sleeve on top of another sleeve. The sleeves are then axially compressed with a force sufficient to overcome the position maintaining arrangement, and the sleeve parts move relative to one another within the cap; the axial compression continues to axially compress the cap. The treatment medium is introduced through the holes in the sleeve.
