Title: Improvements in or relating to cross-linked polystyrene resins
Inventor: FICKEN GEOFFREY ERNEST
IPC: C08F8/44
Filed: 1955-07-14
Abstract: Amino substituted cross-linked polystyrene resins are prepared by condensing a chloromethylated cross-linked polystyrene resin with hexamine to produce a resin containing hexamethylene tetrammonium chloride residues.  The chloromethylated polystyrene cross-linked, for example with divinyl benzene and/or ether is heated with hexamine in a solvent such as ethanol, chloroform, dimethyl formamide, and dioxane.  Sodium bromide or iodide may optionally be added to the condensation reaction to promote formation of quaternary salt.  The products may be washed with warm chloroform, aqueous alcohol and dried and the resins treated with formic or acetic acid; by a stream of anhydrous hydrogen chloride; by refluxing with concentrated hydrochloric acid, or 0.88 ammonia solution; or by standing overnight in alcohol saturated with hydrochloric acid.  The resins may be used as intermediates for, or as ion-exchange resins.

Title: Improvements in or relating to stencilling-machines
IPC: B41F15/08
Filed: 1930-07-05
Abstract: 360,828. Stencilling- apparatus. HART, F., 2749, San Marino, Los Angeles, U.S.A. July 5, 1930, No. 20455. [Classes 100 (i) and 100 (ii).] In stencilling-apparatus of the kind comprising an endless belt which carries the stencil and which travels over a platform on to which the work is fed, guides are provided on the platform adapted to engage the margins of the belt to prevent buckling thereof and to ensure the coincident advance of the belt, stencil, and work. In one form, a stencil, consisting of fabric blocked out in the usual way and mounted in a frame, is attached to a metal belt d, Figs. 2 and 3, passing over positively driven rollers 34, 35 provided with teeth engaging perforations near one edge of the belt. The lower stretch of the belt passes over a platform c on to which cards &c. b laid on an endless band a are fed, and the marginal edges of the belt and the stencilframe engage slots 7 in guides 5, 6 mounted on the platform. Each card as it arrives on the platform is pushed against a side gauge n which is subsequently depressed by blocks 77 carried by the belt d, whereupon projections on the belt engage the rear edge of the card and feed it through printing position. Colour is applied by a pipe f supplied from a container 65, and is pressed through the stencil by a spring-pressed squeegee g. Three methods of attaching the stencil frame to the belt d are described. (1) Tongues on the frame engage dovetail slots in the belt. (2) A thickened part on the edge of the frame abuts against a shoulder on the belt, screws being passed through the overlapping parts. (3) Projections on the belt and the frame are folded on themselves to provide hooks which interlock. In a modified form of apparatus, the cards are fed completely through the machine bv an endless band. Pile tables.-An automatic feed for the cards comprises a pile-table 203, Fig. 14, which is raised each time a card is removed by a projection 200 on a feed band u. The card passes over a table 204 and engages the end of a trip lever 207 adapted to release a one-revolution clutch 208 whereby a crank 210 is rotated and, through the intermediary of a rod 211 and a ratchet device, turns a screw engaging a nut fixed to the table 203.

Title: Improvement in the functioning of continuous vacuum distillation or rectification apparatus
IPC: B01D3/10
Filed: 1950-08-21
Abstract: <PICT:0683781/III/1> In the recovery of volatile compounds, e.g. alcohol, escaping with gases and air from the last stage of a vacuum distillation or rectification plant, e.g. for distilling alcohol, the mixed gases and vapours are drawn off by a liquid ring-type pump and discharged with the liquid operating the pump into a washing column where the vapours are condensed by contact with a liquid, e.g. water, flowing down the column, while the gases are evacuated to the atmosphere, and the liquid collecting at the base of the column is in part recirculated as the working liquid of the pump, the remainder being drawn off and made up for by the fresh washing liquid introduced into the column, thus maintaining constant the percentage of alcoholic &c. vapours dissolved in he pump-operating cycle. Vapours from a distillation plant (not shown) enter a tubular condenser A through pipe 1, condensate being withdrawn by a pipe 16. Residual vapours and gases are withdrawn through pipe 2 by a ring pump B and injected into a column CD through a tangentially arranged orifice 4 which in conjunction with a baffle 7 gives a gyratory movement to the liquid-gas mixture.  Vapours and gases rise through the plates 8 against a downward flow of washing liquid fed through line 15.  The vapours are condensed by the washing liquid while gases are evacuated to the atmosphere through line 17.  The aqueous alcohol collects in a tank E provided with cooling tubes F and is recirculated in part by a pump G to the ring pump B.  The alcoholic content of the solution is stabilized by removing part of the water through line 13 provided with a flow gauge H and controlling by a float cock J the supply of washing water in the pipe 15 to maintain a constant level in the tank E.  The aqueous alcohol taken off at 14 is returned to the process.  The arrangement described is stated to reduce the noise of the ring pump.

Abstract: 808,420. Drying food concentrates. VACUDRY CO. July 18, 1955, No. 20718/55. Class 49. [Also in Group XIII] A continuous method of drying concentrates of liquid and semi-liquid comestibles, especially concentrates of citrus fruit juices such as orange juice, to powder, without impairment of flavour on reconstituting the powder, involves forming the concentrate into a layer of uniform thickness, heating and puffing the layer, removing the desired amount of water therefrom, and rapidly cooling the layer, the layer being kept at its pseudo-melting point during the greater part of the heating stage and being subjected to sub-atmospheric pressure during the operations. With the apparatus of Fig. 1, the drying is effected in a casing 1 evacuated through a pipe 14; the concentrate introduced by a pipe 7 is transferred from a pan 8 by a roller 9 to the lower surface of the lower flight of a metal belt 4 moving round a heated drum 5 and a cooled drum 6, is heated by electric radiators 11a-11d, is further heated on passage of the belt round the drum 5, is further heated on the upper flight of the belt 4 by electric radiators 12a-12f, and is cooled on passage of the belt round the drum 6, the dried layer being then detached from the belt by a doctor blade 15 into a hopper 16 and fed therefrom through an air-lock 17 into a receiver 18.
