Title: Planting device
IPC: A01C11/00
Filed: 1972-02-08
Abstract: 1386862 Planting device KOPPARFORS AB 8 Feb 1972 [9 Feb 1971] 5847!72 Headings A1B and AID A planting device includes a rotating downwardly pointing hollow cone 1 formed by at least two cone parts 2a, 2b pivoted about pivots 3a, 3b respectively on a holder 4 and arranged with their adjacent edges 6, 5 radially separated leaving a longitudinal gap 7 between them. The cone halves extend upwardly to form members 8a, 8b which engage a locking member 9 with its outer surface matching the conical shape of members 8a, 8b. Cone parts 2a, 2b are thus held closed together. In operation the planter is rotated by the hollow shaft 12 and plants, fed down the shaft and guided through a central opening in holder 4 by rods 17 downwardly depending from the holder, come to rest against the cone surface. The planter is lowered into the earth and the soil loosened by the outer edge which leads with respect to the direction of rotation, is pushed, by the rotation, through opening 7 and into the cone 1 where it is packed around the tuber 18 of the plant, while tools 19, 20, fixed to holder 4 at different radial distances from shaft 12, cultivate concentric regions of ground surface. Then, by means of wires (not shown) attached to eyes 16 of bolts 13 fixed to plate 11, the plate 11 is raised to the level of plate 15 secured vertically to shaft 12, taking with it locking member 9 which is held to plate 11 by flange 10. This leaves cone parts 2a, 2b free to pivot as members 8a, 8b no longer engage member 9. and further raising of plate 11 lifts the whole device leaving the plant in the soil.

Abstract: 896,790. Attaching sleeves to spinning &c. spindles. TOYO RAYON KABUSHIKI KAISHA and NIHON SPINDLE SEIZO KABUSHIKI KAISHA. Feb. 20, 1959 [Feb. 21, 1958], No. 5968/59. Class 120(2) To support a sleeve on a spinning &c. spindle, the top of the spindle is fitted with a tip 4 having a cam 7 with guide surfaces along which members, such as rollers or balls 8, can rotate while moving towards or away from the sleeve according to their positions on the surfaces. The cam surface has portions of steep and gentle inclination 5, 6, and recesses. Cam 5, 6 and the balls &c. are held by a retainer 9 which may have friction members 13 or otherwise be partly or wholly in contact with the inner surface of the sleeve. When the spindle starts to rotate, the cam 7 forces the balls into contact with the sleeve; when the spindle slows to a stop, the continued rotation of the sleeve causes the balls to move on to the shallow parts of the can surface to force the balls against the sleeve and bring it to rest. When the sleeve is to be removed, the balls move into the recesses in the cam-surface. The cam may be integral with the spindle, and resilient means may be provided to reduce the impact between the cam and the balls on starting and stopping. The arrangement permits the use of a short and narrow spindle.

Filed: 1967-02-08
Abstract: 1,125,365. Clamps. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 8 Feb., 1967, No. 5977/67. Heading E2B. A clamp for electrical wiring conductors comprises a screw member 15 and a body 18 having a threaded aperture through which the screw member can be screwed to cause a clamping force to be exerted between a fixed clamping member and a movable clamping member which is movable by the screw member together with a resilient member 17 which is positioned for engagement of said body and is effective due to its resilience to prevent on such engagement, turning of the body on screwing of the screw member to exert such clamping force until a certain value of clamping force is reached at which value further screwing of the screw member will result in turning of said body against the resilience of said resilient member so that the screw member and said body will turn together and thus the clamping force will not be increased further by such further screwing. In the construction shown the clamp includes a generally U-shaped frame 1 having side flanges 2 and 3 by means of which the clamp can be secured at a desired position each of the flanges 2 and 3 having for this purpose two threaded apertures therein into which screws 4 can be screwed. The base of the frame 1 has secured to its inner side the fixed clamping member which comprises a metal plate 5 and a pad 6 of rubber or other resilient material bonded to the plate 5. The movable clamping member comprises a metal plate 7 and a pad 8 which is also of rubber or other resilient material and is bonded to the plate 7. The plate 7 has two projections 9, 10 which engage respectively in slot keyways 11, 12 which extend longitudinally in the two limbs of the frame 1 to guide the movement of the movable clamping member, towards the outer ends of the frame limbs Ithe two keyways are enlarged to receive a crossbar member 16 and the outer edges of the resilient member which is U shaped and which straddles the member 16. The screw 15 passes freely through apertures in the crossbar 16 and the spring member 17 and through a washer 19 or plastics material and a nickel plated washer 20 which are bonded together and screw's into the body 18 which as shown is a nut. The engaging surfaces of the washers 18 and 19 with the nut and the crossbar member prevent the slipping action of the nut being impeded. In a modification the washer 20 is omitted in which case the crossbar member is nickel plated.

Patent GB-710537-A (GB)
Title: Process for the polymerization of olefins
IPC: B01F13/10
Filed: 1952-03-12
Abstract: Lower olefins are polymerized to polymers of gasoline boiling range in the presence of a finely divided, solid polymerization catalyst maintained as an agitated suspension in a hydrocarbon phase, at least part of said catalyst being subjected to mechanical action to reduce the particle size and provide fresh surfaces for exposure to the reactants, said mechanical <PICT:0710537/IV (b)/1> action being controlled to maintain the activity of the catalyst substantially constant.  The size reduction may be effected by continuously or periodically subjecting at least part of the catalyst to mechanical attrition, grinding or pulverizing means. Catalysts effective at about 350-600 DEG  F., and pressures of, e.g. 20-1000 p.s.i.g. or more, according to whether the hydrocarbon is in a true vapour or liquid or liquid and vapour phase, are used and include "solid" phosphoric acid, preferably made by drying and calcining a mixture of silica hydrogel and the acid, copper pyrophosphate, zirconia, thoria and activated alumina, if desired with supports.  The fresh catalyst has a particle size of 40-600 microns, and may be reduced to a final size of 2-150 microns depending on the efficiency of the separating means for treating the effluent.  The surface area of the particles should increase at 0.5-10, preferably 2-6 per cent per hour.  The feed may contain 30-90 per cent or more of olefins, ethylene generally being low.  The reactor 11 has a stirrer 13 with vertical vanes 16 inclined at an angle to the edges of support 17.  A speed of 200 r.p.m. keeps the catalyst of 70-450 microns size in suspension, while baffles 18 serve to settle particles larger than 3 microns, the product leaving at 21.  The stirrer speed is increased by 50-100 r.p.m. as needed to maintain the conversion by pulverizing catalyst. When a point is reached at which increased speed does not suffice, part of the catalyst slurry is withdrawn to pulverizing means 26 and recycled by line 28.  Fresh catalyst is added and slurry withdrawn as necessary.  In modifications, the pulverizing means is located within the reactor or the feed is jetted at high velocity against an anvil, the slurry being inducted and catalyst disintegrated.  In a hindered settler type of polymerizer, conditions may be adapted to give liquid and gas phases in contact, the liquid phase containing catalyst being drawn off and recycled lower down where it is jetted against an anvil.  Examples illustrate the rate of attrition and surface area increase of catalyst and the relationship with activity in the polymerization of C3 feeds, using phosphoric acid-silica gel with and without nickel phosphate, and phosphoric acid-kieselguhr-active carbon.
