Patent FR-2217060-A1 (FR)
IPC: B01D15/04
Filed: 1973-02-08
Abstract: 1383734 Wet separation of particular materials CRANE CO 30 Jan 1973 4648/73 Heading B2H Particulate mixed, e.g. spent, ion exchange resins are reclassified into separate cation and anion exchange resin fractions by introducing the mixed resins into the top of a vertical column of liquid in which the cation and anion exchange resins settle at different rates of. fall, thereby separating into distinct fractions which are separately collected, the reclassification being enhanced by maintaining a laminar downward flow of liquid in the vertical column. The laminar flow of liquid operates to streamline the particulate resin flow and limits random vertical movement of the particles resulting in a reduction in the total number of particle collisions. Moreover the downward flow of liquid enhances the settling of the larger as compared with that of the smaller particles: The liquid used is preferably water and the laminar flow has a Reynolds number of between 200 and 2200. A resin-receiving vessel is preferably provided above, and adapted to communicate with, the vertical redassification column and an upward current of liquid is set up in this vessel to effect backwash of the resins to remove the fines and/or preliminary redassification of the resins prior to their passing from the vessel into the column. Reclassification may also be enhanced by increasing the buoyancy of one of the types of resins in the vertical column by maintaining a dispersion of air bubbles in the liquid therein and contacting the particulate resin with a hydrophobic, aerophilic flotation agent which selectively adheres the cation or anion resin to the air bubbles. Flotation agents specific to anion exchange resins may include a polyamine alkyl sulphate, xanthate, dithiophosphate, dithiocarbamate or an arenesulphonate. Flotation agents specific to cation exchange resins may include a polyacrylamide, primary amine, quaternary amonium salt, primary ammonium, alkyl-pyridinium salt or a thiocarbanilide. A suitable plant is described.

Title: Part cooked rice dish prodn - for canned convenience meals
IPC: A23L7/196
Filed: 1973-04-09
Abstract: A stock comprising juices, oils, fats, spices etc. is prepared and predetermined quantities are used to part cook the rice, to a degree of 20-50% depending on the quantity and type of rice. During this process all the stock is absorbed so that the grains are fully impregnated with the flavouring and spices and the rice has a predetermined moisture level after which it is canned. Additional ingredients (meat, fish, vegetable, etc.) may be added without any additional liquid and after sealing the cans are sterilized. Due to the low liquid content, the rice does not cook any further and final cooking takes place after emptying from the can and before serving.
Patent FR-2225122-A1 (FR)
Title: Articulated paper or plastic straw - has hinge formed by pleated section or similar along section of straw
IPC: A47G21/18
Filed: 1973-04-13

Title: Flame height regulator for gas lighter - has expansion filter compressible at periphery and centre
IPC: F23Q2/173
Filed: 1974-07-04
Abstract: The flame is regulated by varying the pressure on an expansion filter pad which connects the gas reservoir with the gas valve. The inlet to the filter is on the periphery of the filter and the outlet is in the centre. The pressure on the filter and hence the flame size may be reduced by screwing down an outer sleeve. This may be achieved by turning the sleeve by means of a special tool available only to the manufacturer. The flow of gas may be further reduced by turning an inner sleeve at a flange. This operation may be carried out by the user.

Abstract: The propulsion unit has a nozzle (7) which receives gas from the combustion chamber. The gas passages consist of a number of perforations (11) in the internal cylinder (10) of the unit. Under acceleration conditions a ring (17) is forced forwards by the force (F1). During transition from acceleration to cruise the ring moves rearwards under force (F2) and releases the hollow nozzle plug which is initially held by pins (16), and the pins may be broken already by the transition. The plug travels towards the outlet nozzle and is retained in the neck (6). Gases are now forced through the nozzle (26) of the plug at higher velocity.

Title: Liquid crystal display block reflecting digital indication - has transparent remote electrode with metallic layer and insulated thin baseplate
IPC: G02F1/1335
Filed: 1974-12-27
Abstract: Liquid crystal display blocks for clocks, measuring instruments or electronic data processing equipment, reflecting a digital indication. The system uses a transparent remote electrode (6) with a metallic layer (5) giving total surface reflection and a thin electrically insulated transparent baseplate (4). The surface of the baseplate is in contact with the metal layer in the display block producing complete surface reflection via a liquid crystal (11). This ensures that the remote electrode plate will not appear hazy and unclear. The illuminating surface of the display block will provide a high contrast because the circumferential shadows of the electrodes will have been more or less made invisible.
