Title: Improvements in or relating to the manufacture of articles containing material at one stage plastic, and particularly in or relating to the extrusion of the said plastic content
IPC: B29C48/07
Filed: 1927-10-31
Abstract: 305,152. Dunlop Rubber Co., Ltd., and Fellowes, F. Oct. 31, 1927. Extrusion machines. - Consists in the production of tapered or bevelled lengths of material by extrusion through a variable die. Figs. 1 and 3 show one form of apparatus, for the production of tyre tubes for india-rubber, wherein the extrusion aperture is formed between a stationary core 1 and a sleeve 2 reciprocable axially by a cam member 8. Through a crank 15, linkage 16 and connection 8a, the member 8 is rocked in such a manner as firstly, to move back the sleeve 2 gradually to close the aperture 7 and bevel the end of one length of tube, secondly to cause momentary closure of the aperture to sever the length and, thirdly, to return the sleeve gradually to open the aperture to bevel the oncoming end of the next length of tube. Fig. 6 shows a modified die for producing tread strips, in which a slit-like extrusion aperture 26 is gradually restricted and freed by a sliding member 25 operated through a crank linkage. In a further modification, for tubes, the die is controlled by an iris-diaphragm device. Tubes may be extruded on to mandrels ready for vulcanization. Fig. 5 shows a tubular mandrel 17 furnished with a ring 18 complementary to the taper of the tube, the ring being either sprung over the taper or formed of segments convergeable by an auxiliary ring 18<a>. This mandrel, and also variable extrusion dies, are disclaimed.

Title: Viscosity control in yarn sizing
IPC: D06B23/28
Filed: 1948-11-10
Abstract: 657,137. Automatic viscosity control systems. DOMINION TEXTILE CO., Ltd. Nov. 10, 1948, No. 29252. Convention date, Nov. 19, 1947. [Class 38 (iv)] The consistency of size in a feed vessel 10 is maintained constant by a device 34- 36 which measures the viscosity of the size and controls through apparatus 40, 41 and valves 42, 44, the flow of heavy and light size from tanks 20, 26 respectively to the vessel 10. The viscosity of the size is measured by the time taken for a piston 36, after being raised by timing mechanism, to displace a predetermined amount of size. This time interval is converted into mechanical movement to operate a spindle 50 which in turn operates a pointer 51 and linkage 58, 56, 54, 52. The lever 52 and associated lever 68 control mercury switches 76 and 70 which control the valves 42, and 44 respectively Initially the lever 52 is rotated to its farthest. counter clockwise position, path switches 76, 70 being open so that no size flows to the vessel 10. As the lever 52 moves; i.e. clockwise direction switch 76 is actuated and heavy size flows into the vessel 10. As the lever 52 continues to move in a clockwise direction both switches are actuated and in the final position switch 76 is broken so that only light size flows to the vessel 10. If the consistency of the size now deviates from that required the above sequence is repeated to effect restoration. A level control 90 is incorporated and is such that at a first level a mercury switch 100 is tripped by a contact 94 to cut-off the supply of light size and at a maximum level a switch 102 is tripped to cutoff the heavy size, the normal level of operation being when the contact 94 is just below the switch 100.
