Filed: 1928-01-30
Abstract: 284,608. Soc. Italiana Pirelli, and Pestalozza, U. Jan. 31, 1927, [Convention date]. Moulding indiarubber.-Latex is treated at a low temperature by adding small quantities of substances such as solutions or suspensions of salts of di- or trivalent metals, and is subsequently heated, whereupon coagulation or thickening of the latex occurs. In an example 1.5 gms. of a slightly soluble calcium salt, and 1 gm. of zinc oxide suspended in ammoniacal water is added to 1000 gm. of ammonia preserved latex containing 50 per cent of rubber. At temperatures below 20 C. no thickening occurs, but on heating to temperatures of less than 100 C.. say 95-97. rapid coagulation takes place. Agitation during coagulation produces a tougher coagulum than that produced without agitation. Fillers, vulcanizing agents, &c. may be added prior to the treatment. The invention is applicable to the making of moulded articles direct by dipping' heated formers into the treated latex. or by filling a hollow mould with latex, heating it, and pouring off the serum, or by extruding through heated nozzles. Tubes may be made by extruding through a heated annular die, or by coagulating on to a heated rod. A partly-immersed heated rotating drum may be used for the production of sheeting, or fabrics may be proofed or threads united into a fabric by passing' them through a heated bath of the latex. Specifications 1111/14 and 240,430 are referred to.

Abstract: 750,535. Controlling feed to grinding mills. SMIDTH & CO., AKTIESELSKAB, F. L. Feb. 4, 1954, No. 3381/54. Class 59. [Also in Groups XXX and XXXV] A device responsive to the discharge rate of material from a crusher 1 onto a discharge conveyer 4 is adapted to reduce the speed of or stop a conveyer 2 feeding material to the crusher when the discharge rate rises above a predetermined value and vice versa. In one form, Fig. 1, two feelers 5, 5<SP>1</SP>, are placed over the discharge conveyer 4, contacts of associated switches 8, 8<SP>1</SP> being connected in series to complete a circuit, when the average height of material on the conveyer rises above a predetermined value, to a relay 11 controlling the speed of the feed conveyer 2, whereby the speed of the latter is reduced. Feelers 5, 5<SP>1</SP> also close other contacts of the switch 8 when the average height falls below a predetermined minimum. These contacts are connected in series with a switch 10 operated by a feeler 9 over the feed conveyer when the level on the latter rises above normal owing to a blockage in the crusher or its feed hopper, so that under these conditions a further circuit is completed to relay 11 to switch off the motor 3 of belt 2 and to actuate an alarm 12. Crusher 1 is of the hammer mill type. Instead of the two feelers 5, 5<SP>1</SP> and switches 8, 8<SP>1</SP>, one feeler and switch may be used by making relay 11 operate only after a delay. In a second form (not shown) flap 9 is omitted and crusher 1 is a jaw crusher for partly crushing the material which then passes from the belt 4 to a hammer mill crusher for further crushing the material. In a further form, Fig. 3, the discharge conveyer 4 is suspended from a weighing machine which operates a relay 17 controlling a further relay 18 either directly or through the switch 10 according to whether the weight is more or less than a predetermined value.
