Title: Injection/blow moulding machine
Inventor: BRACKENBRIDGE WILLIAM GEMMELL
IPC: B29C49/06
Filed: 1966-05-26
Abstract: 1,103,846. Injection/blow-moulding; transfer mechanism. BLEWIS & SHAW (PLASTICS) Ltd. 26 May, 1966, No. 23644/66. Heading B5A. An injection/blow-moulding machine in which there is a plurality of blow-moulds (e, g, 1, 2) for each injection mould, e.g. 3, has mechanism D to transfer a " parison stick " i.e. injection core between the injection and blow moulds, the parison stick being disconnected from the transporting member on completion of such a transfer. Each transporting member may serve an injection mould and a number of blow moulds. The moulds may be multicavitied, each parison stick of one mould being connectable simultaneously to the transporting member, e.g. the sticks may be attached to a single holder 5, engageable by the transporting member, e.g. by socket 6. The transporting member(s) may be operable by hydraulic or pneumatic cylinders, preferably double-acting. Movements of the transporting member may be controlled by valves responsive to the termination of the preceding movement, e.g. electrical limit switches operated by strikers on parts of the machine which move relatively (Fig. 3, not shown). There may be a plurality of injectionmoulds, each with its own set of blow moulds and transfer mechanism. In the embodiment shown in Fig. 1, the machine comprises two blowmoulds (1, 2), an injection-mould (3) equidistant therebetween and transfer mechanism D comprising two horizontally opposed limbs (8, Fig. 4, not shown) each connectable to a parison stick or holder by means of bolt (16) which passes through a lateral bore in the stick or holder to retain it in socket 11. From the position when the parison sticks are in blowmould 1, and injection-mould 3, mechanism D descends to engage the holders, 4, 5, and raise them clear of the moulds. The arms are then rotated through 180 degrees so that holder 5 is above blow-mould 1 and holder 4 is above injection mould 3, and lowered to position the parison sticks therein. After the holders have been disengaged, the mechanism is raised and moved across to the position shown in dotted lines in Fig. 1, so as to enable a new cycle as above to be repeated.

Abstract: 393,448. Honeycomb paper. WEISSING, H., 2, Bismarckplatz, Grimma, Saxony, Germany. Aug. 31, 1932, No. 21307. Convention date, Oct. 22, 1931. [Class 96.] Festoons, garlands, &c. are made by winding on to a large drum pairs of paper webs in offset relation, or of different widths, or both. As shown, pairs of webs b<1>, b2, cl, c<2>, &c. are wound in staggered formation on the drum a, each web being gummed on its inner surfaces at the side edges d, q, and along a line f on its outer surface, the lines f being in vertical alignment. When the paper is opened out as shown in Fig. 2, the parts e between the gummed edges d and the connecting parts f are in line. The edges q may be left ungummed so that the lower parts of the webs hang loose. The webs may be wound inside additional webs g, h, Fig. 4, which may be stuck together at their lower edges or allowed to hang loose, or webs may be enclosed within the pairs b<1>, b2, &c., the upper edges being stuck to the parts e. In modifications, pennant-like webs may be suspended from the lower parts of the webs bl, b<2>, from an outer pair of webs, or from the gummed parts d, f, q; the webs b<1>, b<2> may hang loose and be connected by further pairs of webs. The Specification as open to inspection under Sect. 91 comprises also a modification in which the webs are connected together midway of the parts hanging down, or, where the parts are of unequal length, the end of each shorter part is stuck to the adjacent section of the complementary part.

A forging manipulator has its peel 8 and jaws 9 mounted for relative longitudinal movement on a wheeled carriage 7 so as to provide a high positive acceleration of the workpiece to a new bite position upon its release by the forging tools. The peel is movable longitudinally against biasing springs 20 by a hydraulic ram and cylinder 23, 23a which are controlled by an electric signal produced upon release of the ingot by the press tools. Rotation of the peel is effected by a slow speed hydraulic motor 24 and gearing 25; a brake 26 is applied automatically when the motor is stationary. Carriage 7 has its wheels 11 running along rails provided on the lower flanges of I-section beams, Fig. 3 (not shown). The upper flanges act to prevent lifting of the wheels. Carriage drive is effected by pinions 15 meshing with fixed racks on the upper flanges of the beams. The pinions are driven by one or more slow speed hydraule motors.

Abstract: 690,538. Cooling dynamo-electric machines. SHEPHERD, G. R. (Westinghouse Electric International Co.). Oct. 24, 1951, No. 24817/S1. Class 35. Axial ducts in conductor slots are formed by pre-formed channels of insulating material extending over the top and bottom portions of the conductor and side insulators resting against the slot walls and against parts of the channel members. As shown, the main insulation of the stator coil sides is comprised by a pair of U-shaped members 22, 23 and side members 25 providing an axial duct along each side of each coil side, this insulation being modified half-way along the coils to enable the ducts 21 to communicate with radial ducts leading to the outer periphery of the core whence the cooling fluid divides and flows towards the ends of the machines. If liquid such as oil is used for the stator, an airgap partition 15 is used to keep it separate from the hydrogen under pressure used for cooling the rotor and passing over vertical coolers 52 at each end of the machine. The rotor conductors may be of channel section to provide axial ducts, apertures being provided in the conductors and slot wedges to enable the hydrogen in these ducts to reach the airgap and then flow towards the two ends of the machine. The stator fluid could also be hydrogen under pressure instead of liquid, in which case the partition 15 could be omitted, or it could be compressed sulphur hexafluoride, or a compressed gas containing a fluorocarbon mist. Mica, pressed board, paper, cotton cloth, or fibre-glass cloth with a bonding resin which may be phenolic urea, melamine, silicone or styrene copolymer can be used for the insulators 22, 23, 25.

An hydraulic extrusion press has a rotatable die-changing assembly comprising a rotatable shaft 5 carrying a die table 10 with at least two sets of dies 13 and bolsters 15, and means for moving the table and shaft parallel to the press axis whilst restraining the bolster against such movement, in order to separate a die from its bolster. Two sets of die and bolster assemblies are mounted in radial slots 17, Fig. 5, of the table 10. Each die 13 is supported in a holder 11 located in keyways in the sides of the slot 17 and held in position by a peg 22. The die and bolster assembly is locked in its operative extrusion position by an hydraulically operated slide 23 which engages in slot 17 and has side members 27, 28 engaging in slots in the bolster 15. At the end of extrusion, the container 30 is withdrawn and the table 10 is moved simultaneously in the same direction by an hydraulic motor 6, 7, Fig. 4 (not shown), acting on the cross-head 8 of shaft 5. Movement of the bolster 15 is restrained by the slide 23 and thus the die and die holder are separated from the bolster to permit a saw blade 34 to sever the extruded product 32 therebetween. Further withdrawal of the container removes the stub and discard 31 from the die. The table is then rotated by a rack 4 meshing with a pinion 3 of the shaft 5.
