Patent GB-946038-A (GB)
Title: Forming of plastic articles
IPC: B29C48/09
Filed: 1962-04-03
Abstract: 946,038. Moulding hollow articles. J. LYSOBEY. April 3, 1962, No. 12721/62. Heading B5A. A method of moulding hollow plastic articles comprises extruding a tube of plastic material, or forming extruded material into a tube, maintaining a pressure greater than atmospheric inside and outside the tube adjacent the extrusion means and then submitting the tubular structure to reduced pressure to force the tube against an adjacent mould surface. Using the apparatus shown, a tube 45, Fig. 2, of plastic material is extruded from the orifice 27 into the enclosure 43. Fluid under pressure is admitted into the tube through the mandrel 48 and into the enclosure through the tube 42 (not shown). The mould halves 16, mounted in sockets 11 on two parallel conveyers, move with the tube away from the extrusion orifice, are closed by the actuation of rods 17 by pneumatic piston and cylinder devices 29, 31, and held together by the bars 39. As the rods 17 move inwardly a valve within each rod is opened allowing fluid under pressure to escape from the enclosure 43 through vents, so that the excess inner pressure expands the tube against the mould. Cutting edges 51 on the base of the mould halves 16 sever the previously formed article while pinching the tube together to form the base of the next article. In another embodiment the tube 71, Fig. 5, is expanded against rotating mould surfaces 81 by the excess pressure within the tube which is kept continuously moving away from the extrusion means by conveyer belts 85.

Title: Apparatus for detecting faults in the armatures of dynamo-electric machines
IPC: G01R31/06
Filed: 1942-09-17
Abstract: 560,124. Detecting faults. C.A.V. Ltd., and CURZON, T. Sept. 17, 1942, No. 13136. [Class 37] Various faults in the armature of a dynamoelectric machine are indicated by the lighting of lamps of different colours or by other indicating devices. A U -shaped electromagnet a subtends an arc at the underside of the periphery of the armature b to be tested. The armature b is supported on the poles of the electromagnet a by means of rollers c, Fig. 2, arranged in pairs, two or more pairs being carried by each pole. The axes of the two rollers of each pair are relatively displaced so that the rollers make contact with the armature at positions separated by an amount differing from the pitch of the slots. The rollers c are annular and are carried by ball or roller bearings on eccentrics e, which are mounted on spindles f extending through the outer ends of the electromagnet poles. The electromagnet a is provided with windings g, h, i and also with an exciting winding f supplied with A.C. from a source k. The winding g supplies induced current to a winding x on a transformer o. The winding h is connected to a lamp p coloured green which indicates that the electromagnet a is in action. The winding i generates relatively high voltage current for testing the insulation of the armature windings and is connected to a neon lamp q and a filament lamp r coloured blue. Between the limbs of the electromagnet a is mounted a U-shaped core u which subtends an arc equal to about twice the pitch of the armature slots and is provided with a winding v connected to an indicating lamp w coloured red. The transformer o carries a winding z, connected to an indicating lamp 4 coloured amber, and also a winding y connected to a pair of brushes 2 engaging adjacent segments on the commutator 3 of the armature b. A short circuit in one or more of the armature windings is indicated by the lighting of the red lamp w. A break is indicated by the amber lamp 4, the windings y, x normally neutralising each other. Lighting of the neon lamp q indieates that the insulation is satisfactory. If there is a fault in the insulation the neon lamp q is short-circuited and sufficient current flows through the blue lamp r to light it. Reverse connection of the winding between two commutator segments causes the windings x, y to assist each other and the amber lamp 4 lights up strongly. If the armature windings are connected to the commutator segments in incorrect sequence the currents in the windings x, y will not be in balance so that during the rotation of the armature b the amber lamp gives a continuous light of low intensity. A cross connection between a pair of armature windings is indicated by alternate lighting of the amber and red lamps 4, w. The lamps may be replaced by other indicating means such a sound producing means or electromagnetically operated semaphores.
