Title: Improvements in presses and moulding forms for plastic material
IPC: B29C43/00
Filed: 1964-06-15
Abstract: 1,042,995. Moulding plastics materials. F. MOELLER, and K. NEUMANN, [trading as VERWALT UNGSGESELLSCHAFT MOELLER & NEUMANN OFFENE HANDELSGESELLSCHAFT]. June 15, 1964 [June 14, 1963; Jan. 18, 1964; March 24, 1964], No. 24690/64. Heading B5A. A press for moulding plastics materials, especially thermosetting resins, by hot-pressing, utilizes a two-part mould 1, 2, which can be held closed under pressure outside the press by hooked tension rods 7, 8, pivotally mounted on eccentrics 5a, 6a. The hooked ends of the rods 7, 8 are drawn by tension springs 16 (Fig. 1, not shown), into positions above pins 9, 10 on the mould part 1, and clamping together of the mould parts 1 is effected by lowering the hooked ends on to the pins 9, 10 by rotation of the eccentrics 5a, 6a by an hydraulic cylinder device (not shown). The eccentrics 5a, 6a are mounted on a mould support 4 which is carried by a slide or a rotary table so as to be movable towards or away from a position beneath the press head. In a modified apparatus the upper part 1 of the mould carries hooked tension rods 27; 28 (Fig. 4, not shown), which are adapted to engage shoulders on the lower mould part 2 and to exert a clamping action when the eccentrics 29, 30 on which they are pivotally mounted, are rotated by the action of press rams 26. During the pressing operation the mould parts 1, 2 are first closed by a piston 25 to which pressure is applied through a fluid in a chamber 24, from which the fluid escapes through a relief valve 36 at a predetermined fluid pressure, to allow the press head carrying the rams 26 to move downwardly to effect the clamping action. In an alternative mould (Fig. 5, not shown), the surfaces of the two mould parts to be engaged together are oppositely convex and are rendered flat by the clamping forces. In another construction (Fig. 7, not shown), the mould is clamped between two plates. The mould parts in a further embodiment (Fig. 9, not shown), are clamped together by the levers 227, 228 pivotally mounted on eccentrics 231 on the lower mould part and adapted to engage over projections 235 on the upper mould part 201.

Title: Electrical con trol apparatus
IPC: H02P9/30
Filed: 1963-06-21
Abstract: 976,606. Automatic voltage control. WESTINGHOUSE ELECTRIC CORPORATION. June 21,1963 [July 2, 1962], No. 24704/63. Heading G3R. In a generator having an output voltage with a ripple component, periodic voltage pulses varying in width according to the difference between the magnitude of a predetermined voltage and the output voltage are produced at ripple component frequency and are applied to control a switching circuit which varies the excitation current of the generator to maintain the output voltage at the predetermined value. As shown, a brushless alternator 10 supplies a load 80 over a full wave rectifier 30 and is provided with an exciter 12 having a field winding 26 connected over a transistor 64 to the output terminals 32, 34 of the rectifier 30. The output voltage at terminals 32, 34 has a ripple component and a proportion of this voltage sensed by the circuit including a temperature compensating diode 66, a potentiometer 58 and a resistor 72, is applied to a reference Zener diode 52 which produces voltage pulses during the times the ripple component causes the output voltage to exceed the breakdown voltage of the Zener diode. These pulses vary in width according to the difference between the output voltage and the reference voltage (Figs. 2 to 5, not shown), and are applied to a transistor 62 which is rendered conductive each time it receives a pulse. Transistor 62 controls transistor 64 which is rendered non-conductive when transistor 62 is conductive; thus, the field winding 26 of exciter 12 is supplied with current in the form of periodic pulses the widths of which vary in accordance with the output voltage of the generator 10 so that an average excitation current is established which maintains the output voltage at a predetermined value selected by adjustment of the potentiometer 58. Positive feedback provided by a capacitor 122 shortens the turn on-turn off time of transistor 64. A diode 110 provides a discharge path for the collapsing field of the winding 26; this discharge path may also include a Zener diode (Fig. 6 not shown) to reduce the excitation current discharge-time after interruption of the excitation current.

Abstract: 1,267,976. Securing yarn to winding mandrel. LOVESHAW CORP. 14 May, 1969 [7 June, 1968], No. 24714/69. Heading D1J. An expandable winding mandrel (Fig. 5) on a turret-type continuous winding machine carries an axially movable clamping plate 55 at its free end, defining a channel 57 between the plate 55 and the mandrel end 48 and means for retracting the plate to clamp a strand in the channel. The plate 55 is fixed to a tubular shaft 52 which rotates with, and is slidable in, the mandrel drive shaft 21. The yarn is aligned with the groove as the mandrel moves to the winding position by a guide 17 (Figs. 1, 2) which is pivoted into the yarn path, disengaging it from a rotating traverse guide 15. The traverse guide is itself reciprocated axially of the mandrel, over a decreasing length to form a package with tapered ends. The mandrel at the doffing station 4 (Fig. 1) may be flushed through with water or other liquid, injected through the shaft 52 and passages 69, 63, 71, 39 and 49, (Fig. 5). Retraction and extension of the shaft 52 is by a double solenoid 75 (Fig. 6) attached to the mandrel drive shaft beyond a driving motor, and supplied with current via slip rings 93.

Title: Improvements relating to injection-moulding of organic thermoplastic materials
IPC: B29C45/72
Filed: 1944-12-11
Abstract: 589,148. Injection-mouldjng. BRITISH CELANESE, Ltd. Dec. 11, 1944, No. 24792. Convention date, Dec. 9, 1943. [Class 87 (ii)] The material, immediately before introduction into the injection cylinder, is preheated by highfrequency alternating electromotive force, and from the cylinder the material is forced into an unheated mould. Fig. 1 shows an apparatus for doing this, comprising a preheating cylinder 6, made of low-loss material, in which the material is heated between a high tension electrode 11 and the earthed injection cylinder 13. The electrode 11 is a metal facing on a plunger 10 of non-conducting material which slides through a cross-head 14. The preheating occurs whilst a previously-ejected charge is cooling in the mould, the injection plunger 20 being then to the right. When the moulded charge has cooled, the plunger 20 returns to the left and plunger 10 forces the preheated material into the injection cylinder. Cold material is fed into the preheating cylinder from a hopper 1 by a piston 3, the hopper itself reciprocating into and out of feeding position on a slideway 8. The injection lever is heated by a coil 25. The mould is cooled by water &c. circulated therethrough. The material moulded may be cellulose derivatives or acrylic or vinyl resins. The Specification as open to inspection under Sect. 91 states that the material, after pre-heating, may be extruded through a die instead of injected into mould, and that the material may be phenol-formaldehyde, ureaformaldehyde, glycerol-phthalic anhydride or polymerized allyl resin, or polystyrene. This subject-matter does not appear in the Specification as accepted.
