Title: Improvements in or relating to the manufacture of a continuous rod comprising a continuous filler wrapped in a continuous wrapper, such as the manufacture of cigarettes
Inventor: POCOCK FREDERICK
IPC: A24C5/34
Filed: 1957-01-30
Abstract: 888,478. Cigarette - making machines. MOLINS MACHINE CO. Ltd. April 10, 1958 [Jan. 30, 1957], No. 3223/57. Class 130. [Also in Groups XIX and XXXV] In a continuous-rod machine, and crosssectional size of the cigarette rod R is gauged by the amount of air which escapes from a chamber 8 by passing between the rod and orifices 9. Due to transient adhesive slip on rod formation, the rod size varies with its degree of filling, which is consequently indicated by the air pressure in the chamber 8, and this pressure is used to control the rate of the machine tobacco feed or to cause rejection or marking of cigarettes formed from unsatisfactory rod portions. To this end, air supplied via ducts 12, 15 to the chamber 8 acts via a diaphragm 3 and peg 24 on an electrical contact 25 coacting with contacts 26, 27 the spacings of which relative to the contact 25 and to each other are adjustable by a wedge 32, slidable on a blade 33 by a rack and pinion (not shown) operated by a knob 40, and movable sideways by deflection of the blade 33 itself by a screwed knob 36a. The air pressure used, e.g. 1¢ lb. per square inch, is insufficient to damage the softest cigarette normally acceptable. A balancing air pressure is supplied to the rear face of the diaphragm 3 via a line 23 including a non-return valve. The apparatus is initially set using a standard rod of metal &c., preferably light enough to float centrally in the orifices 9. In a machine for making mouthpiece cigarettes, the apparatus can be used to keep the rod R to a given mouthpiece size, e.g. by adjustment of a rod heater means like that of Specification 284,819. In Fig. 4 (not shown), the contacts 26, 27 may coact with a second diaphragm flexed by the diaphragm 3 via an air relay and integrating chamber, and control a reversible electric motor actuating the regulator of a variable speed gear, as in Specification 618,774 or 860,185, in the tobacco feed hopper drive. In a modification, in which the diaphragm 3 itself coacts with contacts 26, 27 adjustable via gear-operated screws thereon, both sides of the diaphragm are subjected to the same source of air so as to cancel out supply pressure variations.

Abstract: 1,111,161. Promoting chemical reactions by radiation. JAPAN ATOMIC ENERGY RESEARCH INSTITUTE. 26 Jan., 1966, [2 Feb., 1965], No. 3411/66. Heading BIX. In a chemical reaction apparatus a radioactive inert gas is circulated through the reaction vessel 11 and acts as a reaction promoter. The entire apparatus is first evacuated by a pump 6, and then a radiation source gas, e.g. Krypton 85, from a source 1 is diluted in a tank 9 with a diluent, e.g. nitrogen, from a source 3, the pressure and dilution of the gas in the tank 9 being measured by gauge 26 and counter 54. Liquid reactants stored in vessel 16, are introduced into the reaction vessel 11, being measured when batch feeding is employed by a vessel 15, or when continuous feeding is employed by a flow meter. The diluted radiation source gas is then circulated by pump 10, a mist separator 14 preventing reactants from entering the circulating system. After the reaction has been completed, the circulation is halted and the radiation source gas is purged from the reaction vessel by heating and cooling repeatedly by movable heated 13 and cooler 12. A small portion of radiation gas to be disposed is collected by trap 17 and released by blowers 20 and 21. The entire system is finally cleaned by passing therethrough clean air or nitrogen by compressor 3.
