Title: Improvements relating to extrusion dies for plastic materials
Inventor: O'BRIEN JOHN VINCENT
IPC: B29C48/05
Filed: 1963-10-04
Abstract: 1,013,706. Extrusion dies. BRITISHAMERICAN TOBACCO CO. Ltd. Sept. 24, 1964 [Oct. 4, 1963], No. 39244/63. Headings B5A and B5B. A die-head for extrusion of filaments or films of a plastic material comprises a chamber for receiving material to be extruded, and a nozzle holder containing a symmetrical-nozzle assembly, the nozzle holder being rotatable relative to the chamber so that the direction of the nozzle or nozzles in relation to the direction of flow of the material being extruded can be reversed for the purpose of clearing blockages from the nozzle or nozzles. By a symmetricalnozzle assembly is meant one having nozzle orifices or slots symmetrically placed in relation to the axis of rotation of the holder. In one embodiment (Fig. 1) a nozzle-holder 1 comprises a cylindrical metal bar having a slot 2 across which is located a partition 3 provided with nozzles 4. The partition may be integral with the holder 1 or fixed thereto by e.g. welding. Holder 1 is rotatable by tommy bars 8 relative to a chamber 5 into which a pressure element, e.g. a screw, forces material through opening 6. Slot 2 is arranged to coincide with a similar slot 7 in chamber 5, in two diametrically opposite positions. Slot 10, in the bottom of block 9, in which chamber 5 is formed, is of the same shape as slot 2 and forms an outlet for the extruded filaments. A heater plate 14 containing elements 15 is fixed to the back of block 9. Holes 17, 18 and 19 serve to introduce pressure and temperature measuring and controlling devices. In use, when a blockage on the nozzles occurs, the nozzle-holder 1 is rotated through 180 degrees so that flow of material through the nozzles is reversed. In a further embodiment, the nozzles are formed in a separate nozzle plate which is clamped to partition 3, a wide slot then being provided in the partition. A slot (Fig. 3) or series of slots may be provided instead of round nozzles for the extrusion of flat films. The apparatus may be used for extrusion of reconstituted tobacco compositions.

Abstract: 1482804 Touch operated switching circuits INTERNATIONAL STANDARD ELECTRIC CORP 10 Sept 1974 [14 Sept 1973] 39454/74 Heading G1N [Also in Divisions G4, H3 and H4] In a digital control arrangement for electronic equipment such as a radio or TV receiver having at least two groups of bi-stable electronic switches IS1, IS2, Fig. 1 each bi-stable switch having an output A11-A14, A21-A24 capable of being set to a reference potential by activation of an input El 1- E14, E21-E24 associated with this particular output only, a common control input 15, 25 individual to each group is connected to a resistor R10, R11 and the voltage drop across which, caused by a transient current from any of the bi-stable switches during the setting of its output to the reference potential or by external impluse affects all the bi-stable switches of the group and causes any output thereof currently connected to the reference potential to be disconnected from the reference potential. The output of the bi-stable switches are connected through decoupling diodes D1-D6 and associated individual weighted resistors R12-R17 to a common connection point from which a control signal is connected to an electronic control element T1. As shown Fig. 1 by touching contacts al and a2 to the centre contact the integrated circuits IS 1, IS2 are reset to select the first bi-stable stage outputs A11, A21. By touching other contacts such as fl and f2 to the centre contact associated bi-stables. in IS and IS2 select currents through resistors R 12 and R 15 to provide control of an element R21, e.g. the sound volume. Resistors R12-14 and R15-R16 provide fine and coarse adjustment respectively. In modifications, Figs. 2a, 2b and 3 (not shown) for sequential control in addition to the individual selection provided by the Fig. 1 arrangement each stage of the circuits IS1 and IS2 are capacitively coupled to the next stage. LED or lamps (L1-L4) Fig 4a (not shown) connected to the outputs of A21-A24 or combinations of outputs such as A11 and A21 are associated with individual lamps (L5-L11) Fig. 4b (not shown) to provide an indication of the selection made. These indicating elements may be seen through a transparent control panel so as to mark the last contact touched. After glowing material may be arranged in the vicinity of the light emitting elements for this purpose. A modified touch contact arrangement is disclosed, Fig. 5 (not shown) which includes a row of sensor contacts arranged in a straight or curved line associated with a counter common electrode (GE).

Abstract: 1,103,611. Coating apparatus. ASHDOWN BROS. & CO. (ENGINEERS) Ltd. 8 Jan., 1965 [8 Oct., 1963] No. 39627/63. Heading B2L. A method of selectively coating the surface of an article comprises locating a masking surface adjacent a region of the surface to be masked, advancing the masking surface into engagement with said region under the action of fluid pressure, coating an unmasked region of the surface of the article and then disengaging the said engaging surfaces by change of the fluid pressure. In the embodiment shown a rotor (dotted lines), parts of which are to be coated with an insulating material, is placed between shoes 12 pivoted to legs 13, the shoes coinciding with the surfaces to be masked. The legs are moved inwards by pistons 19 under the action of fluid pressure supplied at 17 to grip the rotor and masks said surfaces. The rotor is then dipped into coating material to coat the unmasked portions. The pistons 19 can be spring loaded as shown or they can be double acting and the apparatus can be adapted to hold a hollow article, e.g. a stator, on its interior surface.

Other acids, e.g. HCI, HNO 3  or citric acid may be used additionally. From 0À1-2% of tricalcium phosphate, magnesium oxide or colloidal silica may be added to improve fluidizability. The gas used may be one or more of air, nitrogen or carbon dioxide; heating may be effected by means of this gas, or by heat-exchangers. The products may be insolubilized by reaction with aldehydes, e.g. formaldehyde, glyoxal, polyacrolein or dialdehyde starch, or by the addition of polyvalent metal salts, e.g. aluminium sulphate, basic aluminium chloride, or zirconyl ammonium carbonate. Compositions comprise, in the examples, starch with: (1) phosphoric acid, urea and tricalcium phosphate, (2) sulphamic acid, urea and silica, (3) sulphuric acid, urea and tricalcium phosphate.
