Abstract: 477,202. Cigarette making machines. LERNER, F. June 16, 1937, No. 16703. Convention date, Oct. 7, 1936. [Class 130] Lengths of cork or like tipping material are severed from a continuously-fed web of the material by perforating the web transversely at suitable intervals, passing the web through feeding and pasting means, and tearing off the foremost pasted length by temporarily clamping it on a suction conveyer travelling at a greater speed than the web. The tipping material may be used to attach filter plugs or mouthpieces to cigarettes. As shown, the web 2 from a reel 1 passes over a roller 3 and a plate 4 to feeding and pasting rollers 5, 6, the roller 5 receiving paste from a container 7. The web is perforated transversely by a perforating knife 17 on a slide reciprocated over a support 16 by a cam 21 and lever 20. The support 16 is reciprocated along a shaft 10 by a cam 15 co-operating with a spring 13.

Title: Method of preparing organopolysiloxanes
IPC: C08G77/00
Filed: 1954-06-08
Abstract: Organosiloxane copolymers convertible by heat to the solid elastic state are made by heating a mixture of cyclic diorganopolysiloxanes, viz. a mixture of [(CH3)2SiO]m with either [(C2H5)2SiO]n or [(C6H5)2SiO]p where m, n and p are integers having values of 3 to 9, 3 to 5 and 3 or 4 respectively, with caesium hydroxide in amount of not more than 2.0 per cent by weight of the siloxane mixture. Preferably the copolymerization is effected by heating the siloxane mixture to 100 DEG  to 175 DEG  C. and then adding the caesium hydroxide thereto.  This method is used in the examples for copolymerizing octamethylcyclotetrasiloxane with (1) hexaethylcyclotrisiloxane; (3, 4, 6) octaphenylcyclotetrasiloxane; and (5) octaphenylcyclotetrasiloxane containing hexaphenylcyclotrisiloxane.  The gummy or highly viscous products may be compounded with fillers, e.g. a -alumina, silica aerogel, talc, lithopone, titania and ferric oxide, in amount of 0.25 to 3.0 parts (by weight) per part of siloxane, and curing catalysts, e.g. benzoyl peroxide and t-butyl perbenzoate in amount of 0.1 to 6.0 per cent by weight of the siloxane, moulded and cured.  The products may also be dispersed in organic solvents and used for coating cloths, e.g. glass cloth.  U.S.A. Specification 2,490,357 is referred to.

The conductive mixture, deposited as a non-flowing paste, may comprise a mixture of copper, nickel and cuprous oxide powders, colloidal silica, and aqueous sodium silicate. The paste is applied according to the desired configuration and the pins 3 inserted in the holes 2, in which they are loose, the pins being supported by fillets 5 of paste. A small quantity of paste may be used at one end of the pin where a given pin 3 is not to be joined to others. For the first composition, the assembly is heated to 1150‹ C., while for the second to 1040 ‹ C. A wet hydrogen atmosphere may be used in the furnace. The sheet and pins should have similar coefficients of expansion. A glass composition may be sprayed on to the assembled board and fired at 870‹ C., the protective coating being removed from the ends of the pins by grinding, or the composition may be applied thinly and carefully only over the sheet and fused conductive mixture. Components may be joined to the ends of the pins by welding, brazing or soldering. Glycerin may be applied to the sheet in the desired configuration, the metal and cuprous oxide powders dusted thereon to the desired thickness, and firing effected.
