Abstract: 1,103,018. Drying and conditioning grain. P. WESTERBY. 4 Nov., 1966 [9 Nov., 1965], No. 49612/66. Heading A2Q. [Also in Division F4] A bed of grain 1, e.g. retained between partitions 2 on a floor 3, is dried and thus conditioned by air issuing from a plurality of oblique side openings 9 in one or more ducts 4. The drying air is passed through the grain in the direction in which it is subsequently discharged through end channels 13, controlled by sliding gates 14, into a trough 11, provided with conveying means 12. An electrically driven fan 7 supplies air, through a header 5, to the ducts 4. In a modification, Fig. 3 (not shown), the air supply to the ducts and discharge of the grain from the spaces between them is effected from the centre of the ducts. Various portable forms of ducts are described.

Abstract: 516,194. Jet pipe relays. ASKANIA-WERKE AKT.-GES. July 13, 1938, No. 20834. Convention date, July 19, 1937. [Class 135] A jet pipe relay for controlling a servomotor is constructed so that the distance 6 between the centres of the inlet orifices of the two receiving nozzles 4, 5 leading to opposite sides of the servomotor is considerably greater, preferably 50 per cent., than the internal diameter 7 of the mouth of the jet pipe 1, and also so that the projections of the axes 10, 11 of the nozzles on to the plane of movement of the jet pipe intersect at a point 13 further from the jet pipe than the said inlet orifices, whilst the projections of the said axes on to a plane AB intersecting the first-mentioned plane and parallel to the two axes first converge, then intersect and finally diverge as viewed in the direction from the inlet orifices of the nozzles to the opposite ends thereof. The distance 14 of the point 13 from the plane 12 containing the inlet orifices is preferably about five times the distance 6 between the said orifices. To cause minimum interference of the returning streams of pressure fluid with that issuing from the jet pipe, the mouth of the latter is tapered to a sharp edge as shown. With the above arrangements, the jet pipe can be moved closer to the receiving nozzles than hitherto and the angle of deflection of the fluid stream entering either of the nozzles is reduced from about 25 degrees to 18 degrees. Also the pressure difference at the nozzles for a given jet pipe deflection is made greater by the above arrangments. This is shown graphically in Fig. 5 (not shown). Preferably the pressure in the nozzles when the jet pipe is in its central position is about 50 per cent. of the supply pressure. The minimum distance between the axes 10, 11 lies below the plane 12.

A process of forming a backing of a cellular material on a carpet comprises applying a layer of a composition which generates its own blowing or foaming agent and at the same time causes a chemical reaction to take place which causes gelling or solidification e.g. a mixture of a polyhydric alcohol, water, a polyisocyanate and a catalyst, to the back of the carpet and passing the thus coated carpet between two parallel surfaces e.g. a moving conveyor on which the carpet is laid and carried at a constant speed and an endless belt overlying the conveyor, the distance between which is equal to the desired thickness of the final product and slightly less than the combined height of the foam and carpet if the foam was free to expand without restriction, and maintaining the coated carpet between the said surfaces until the foam is completely set. The composition may be applied by spreading. The surface on contact with the foam may be smooth polished or matt to impart the desired surface finish to the cellular material.
