Title: Chlorine manufacture
Inventor: DIPROSE GORDON
IPC: C01B7/05
Filed: 1957-07-31
Abstract: Gaseous nitrogen dioxide is reacted with agitated solid ammonium chloride particles in the presence of an amount of water equal to less than 5% by wt. of the ammonium chloride to yield nitrosyl chloride which is subsequently oxidised by known methods (as exemplified) to give chlorine and regenerate nitrogen dioxide. Nitrogen dioxide, diluted if desired with N2 or air e.g. as in gases obtained during the catalytic oxidation of ammonia, is passed preferably at a low temperature e.g. 21 DEG C., at atmospheric pressure, over agitated solid ammonium chloride either alone or in admixture with sodium chloride with an amount of water which is between 2.0-0.25% by wt. of the ammonium chloride.  Reference is made to the subsequent oxidation of nitrosyl chloride by mixing it with oxygen and passing the mixture over a silica or alumina catalyst at a temperature of 200-250 DEG C. and separating chlorine and nitrogen dioxide by fractional distillation of the liquefied oxidation products.

Abstract: 857,110. Coating webs. DORNBUSCH, P. [trading as DORNBUSCH & CO.]. July 29, 1958 [Feb. 10, 1958], No. 24320/58. Class 140. [Also in Group XIII] An apparatus for the continuous application of patterned coatings of synthetic material pastes 7, i.e. synthetic thermoplastic or thermosetting materials, on a continuous web 1, e.g. of paper, textile or metal foil, comprises a double-walled blade 9 forming the gapped inclined lower surface of a hollow-walled container 10 for the paste, the blade 9 being mounted adjustably relative to an impression roll 6 and a counter-roll 3, and means for feeding the web 1 between the rolls 3, 6, the hollow walls of the container 10, the blade 9, and the rolls 3, 6 being adapted to receive a temperature-regulating medium. The side of the container 10 facing the roll 6 is a double-walled, vertically-adjustable beam 12 which is adapted to receive a heating or cooling medium. The paste 7 may be polyvinyl chloride or polyethylene, polyvinyl acetate or condensation products of phenol resins and the temperature of the medium supplied to the blade 9 and beam 12 is such as to maintain the paste in uncoagulated condition in the container, whilst the temperature of the roll 6 is arranged, by passing heating or cooling medium through the roll 6, which is hollow, to initiate coagulation of the paste 7. The roll 3 has a jacket 5 consisting of alternate layers of asbestos and aluminium foil, and the pattern on the roll 6 may be net-like. A stirrer 13 and a slide 14 are linked together about a pivot 17 so that raising of the stirrer 13 lowers the slide 14 and vice versa. In a modification, the stirrer 13 is a hollow wedge through which a heating or cooling medium is conducted, and a pump circulates paste between a reservoir and the container 10 which has an overflow leading to the reservoir. The storing and spreading mechanism may be pivotable as a unit to shift the point of application of paste to the roll 6 towards or away from the point B. The blade 9 may abut the roll 6, in which case an openwork pattern of paste is provided on the web 1, or be spaced therefrom.

Title: Improvements relating to apparatus for filling containers
IPC: B29B13/00
Filed: 1948-09-17
Abstract: 661,666. Automatically varying the weights of successive weighings. COLGATE-PALMOLIVE-PEET CO. Sept. 17, 1948 [Sept. 19, 1947], No. 24436/48. Class 143 [Also in Groups XXIX and XXXV] In a system for filling containers with granular material the volume of material dispensed into each container is varied in accordance with the weight of two or more filled containers to correct the weight of subsequent containers. In apparatus for filling containers e.g. 7, Fig. 1, with granular material comprising a volumetric filling device 2, 3 for dispensing a predetermined volume of material into each container, corrections are made in the volume dispensed to compensate for variation of density and thus ensure that each container contains the same weight of material. This correction is effected by weighing the containers as they pass from the filling machine A on the conveyer 11, any variation being detected by a weighbeam 24 which effects control of a motor 31 and thereby adjusts through gearing 13-16 a cup 4 which varies the volume of material delivered to the container 7. The speed and direction of the motor 31 may be controlled by a pair of discharge valves, the operation .of which is governed by phase control of the grids by saturable core reactors the D.C. windings of which are differentially responsive to the output of a photo-electric cell 30, the light on which is governed by a shield 28 on the weighbeam. The circuits of the motor 31 are periodically energized by a switch 27 operated by a cam 35 driven from the conveyer, the cam 35 also periodically freeing the weighbeam through linkwork 38a. After the weighbeam assumes its position of equilibrium depending on the weight of the containers, it is arrested by linkwork 43, 44 and subsequently restored to neutral locked position by the linkwork 38a and V-blocks 34. Modified systems are described wherein (1) the photo-electric control is dispensed with by the provision of switches directly controlled by the weighbeam and operating a change-over switch for the motor 31; (2) the motor 31 is replaced by a fluid motor; (3) the weighbeam controls the position of a jet for operating a pneumatic relay which controls a fluid motor; (4) the discharge valves of the electric motor control system may be controlled by variable impedances directly operated by the weighbeam; (5) the weighbeam operates mechanically, a reversible step-by-step ratchet motor for adjusting the cup 4.
