Abstract: 1,266,551. Delaying germination of seeds. BADISCHE ANILIN- & SODA-FABRIK A.G. 9 July, 1969 [10 July, 1968], No. 34523/ 69. Heading A2Q. Germination of seeds to be planted, e.g. in the autumn, is delayed by employing an envelope containing the seed grain or grains together with at least 20 per cent by volume of air or other suitable gas containing molecular oxygen with reference to the volume of the seed grains. The envelope is preferably of synthetic plastics material which may be a thermoplastics material. A hydrophobic plastics material is preferably used. Suitable plastics materials quoted are polyethylene, polyvinyl acetate or other polyvinyl ester of a carboxylic acid, polyvinyl chloride, high impact strength or other styrene polymer or A.B.S. or other styrene copolymers. The plastics material may contain fertiliser salts or other material beneficial to the development of a seedling, or such material may be contained within the envelope. Preferably from 30 to 90 per cent by volume of the contents of the envelope is air. The seed grains are preferably deposited one or two at a time in successive depressions formed in a sheet of plastics material, after prior treating with a fungicide, together with fertiliser, and a second sheet of plastics material is then affixed to the first sheet to form a plurality of seed-containing envelopes which are then separated from each other.

Abstract: 1314421 Preferential deposition of metals UNIVERSITY OF SALFORD 19 April 1971 [31 March 1970] 15287/70 Heading C7B A method of preferentially electro-depositing one or more metals from a multi-ionic aqueous electrolyte comprises dispensing an immisable solvent in the aqueous electrolyte to form a twophase dispersion so that the ions of the other metal or metals are preferentially transferred to the dispersed solvent so that during electrolysis the first mentioned metal or metals are preferentially deposited. The immiscible solvent is kept dispersed by mechanical agitation. In a first example zinc is preferentially deposited in the presence of iron using a dispersion of 50/50 Naphtheric acid and benzene. In a second example cobalt is preferentially deposited in the presence of nickel using a dispersion of sodium di 2-ethyl hexyl phosphoric acid.

Abstract: 1316580 Rolling GEORGE JONES Ltd 8 Jan 1971 [10 Oct 1969] 49848/69 Heading B3M [Also in Division B8] A jacking device comprises a fluid-operated jack assisted by a mechanical jack operable in parallel, and control means for maintaining the force exerted by the mechanical jack within predetermined limits by varying the force exerted by the fluid-operated jack. The device may be used in tension or compression and applied to horizontal, vertical or universal twohigh, three-high or four-high rolling-mill stands; it may be a spacer between work-roll or supportroll chocks, or a pre-stressing device exerting pressure on the roll chocks in opposition to rollseparating forces. The jacks may be integrated or separate, and two screw-jacks may be association with a single hydraulic jack. As applied to spacing the support rolls 14, 15, Fig. 1, in a four-high rolling mill stand, a pair of integrated jacks is used between the chocks 16, 17 in each frame 18. Each jack unit has a balancing ram 43 in a cylinder 32 and a screwthreaded jack shaft 37 engaging a nut 36. A thrust bearing 35 supports the nut on a load cell 34, and the nuts are driven, through gearing 38, 42, by hydraulic motors 50a, 50b. The frames are pre-stressed by hydraulic rams 21, 23 acting against the chocks 16, 17. Admission of fluid pressure below rams 43 relieves the screw of some of the load that would otherwise be transmitted through the nut 36, bearing 35 and cell 34 to the frame 33. The other jack unit in the frame has a dummy load cell, and chocks 12, 13 for the work rolls 10, 11 are separated by springs and hydraulic rams (not shown). The four balancing rams 43 are connected to an hydraulic pump through a control valve forming part of an electric control circuit including the two load cells 34. A separate pump and control valve is used for the rams 21, 23. Rollers 44, 47 on rails 45, 46 facilitate dismounting of the chocks. After pre-stressing by means of the rams 21, 23, the screw elements are operated and at the same time the balancing rams 43, so as to relieve the screw elements. During a rolling operation, a reduction of load on the screw elements is sensed by the load cells 34 and the control circuit operates automatically to reduce the fluid pressure on the balancing rams 43 and restore the loading on the screw elements. To compensate for deflection of the rolls and their bearings, a pressure transducer senses the pressure on the balancing rams 43 and the transducer readings are applied to the control circuit to determine the change required in chock-spacing, the screw elements being adjusted automatically to maintain constant rollgap. Automatic gauge control may also be provided by an electric thickness gauge monitoring the finished strip.

The elastomeric member preferably has a square section and is preferably formed of a silicone rubber. The article produced by the process has a peripheral region corresponding to the shape and form of the nip and may be subsequently trimmed to remove this region. The assembly may comprise one or more layers of the reinforcing material e.g. a woven or non-woven glass fibre mat, a woven or non-woven cellulosic material or a synthetic fibrous material e.g. nylon, polyethylene terephthalate or polyacrylonitrile. The thermosetting resin may be an epoxy or polyester resin and may contain fillers, catalysts, hardeners or pigments. In a preferred embodiment, the process is used in the formation of a laminate having a metal cladding c.f. of aluminium, copper, steel, nickel or a cupronickel alloy on one or each surface thereof.
