Title: Apparatus for cleaning root crops
IPC: A23N12/02
Filed: 1961-12-14
Abstract: 928,370. Cleaning root crops. ELFA APPARATE-VERTRIEBS-G.m.b.H. Dec. 14, 1961 [Jan. 18, 1961], No. 44774/61. Class 117. Apparatus for cleaning root crops e.g. sugar beet end pieces and fragments removed in a cleaning operation comprises a tank 2 having means 9 at its bottom end to supply an upward flow of water, an overflow 3 from the tank connected with a downwardly directed water outflow passage 4, and at least one rotary comb 5 mounted for rotation at the top of the outflow passage 4 to form a cover for the passage and providing means whereby cleaned root crops are thrown from the apparatus through an opening 15. Beet end pieces and fragments together with stones, sand, earth, leaves, straw' grass and other debris are fed to the tank 2 by a supply worm 13. Stones and other dense impurities drop through an outlet 2a into an outlet 12, whilst sand and earth eventually settle into a tank 10 and are removed. The water flow is directed obliquely upwards and the beet fragments are carried with the grass and leaves along the overflow 3 to the combs 5. These combs are formed by toothed discs spaced on rollers 6 so that they intermesh. Alternatively spiked discs or rollers may be employed. The grass, leaves and straw are taken up by the combs 5 and are carried with the water, which also clears the combs, away in the direction of the arrow 14, whilst the beet fragments, which are too large to pass between adjacent discs, are thrown out of the opening 15. The two combs 5 are rotated in the same direction by an electric motor, the second comb encountered by the flow through the apparatus preferably being rotated at a higher peripheral speed than the first to break up any tangled grass and straw.

Title: Mud-guards
IPC: B32B15/08
Filed: 1972-10-04
Abstract: 1409276 Laminated metal-plastics mudguards SEKISUI JUSHI KK 4 Oct 1972 [6 Oct 1971] 45768/72 Headings B5N and B5A [Also in Division B7] A mudguard for cycle wheels comprises a layer 1 of non-transparent, rigid, thermallyresistant synthetic resin, a metal foil layer 2 and a transparent weather-resistant synthetic resin or cellulosic plastics layer 3. The mudguard may be provided with continuous or intermittent longitudinal projections, e.g. as shown at 4, 5. Suitable cross-sections are illustrated. The layer 1 may be thermoplastic, e.g. ABS resin, polycarbonate, polypropylene, polyethylene or polyvinyl chloride, or thermosetting, e.g. unsaturated polyester, phenolic resin, and may be reinforced by glass, carbon or metal fibres dispersed therein or laminated therewith as a mat or woven fabric, or by a metal plate laminated thereon or embedded therewith. The metal foil 2 may be Al, Sn, Cu, stainless steel, brass, alloy or a metallized resin film, and may be reinforced with synthetic resin or paper. The foil may be coloured, patterned or embossed. The layer 3 may be plasticized polyvinyl chloride, methacrylic resin, cellulose acetate butyrate, polyester, cellulose triacetate or polyvinyl fluoride. The layers may be adhered by pressure-sensitive or heat-sensitive adhesive and the metal foil 2 may be slightly narrower than layers 1, 3. In examples, an Al foil coated on both sides with adhesive is disposed between layers of ABS resin and cellulose acetate butyrate. The mudguard is made by forming a laminate of the three layers, forming the laminate into the desired cross-section in a shaping die, solidifying, bending to a predetermined curvature and cutting to a predetermined length. The laminate is preferably formed either (i) by extruding layer 1 and successively pressing preformed layers 2 and 3 thereon (see Figs. 5/6, not shown), or (ii) by feeding a foil 2 through the die of an extruder wherein it contacts layer 1 as it is being extruded, and extruding layer 3 on to the foil 2, suitably in the same die. (See Fig. 7, not shown). After shaping to the desired cross-section, the laminate is solidified by cooling if layer 1 is thermoplastic or by heating to just below curing point if layer 1 is thermosetting. The material is bent around a series of appropriately-shaped rollers lying on a predetermined line of curvature; if layer 1 is thermoplastic the material may be softened by infra-red heaters, whereas if layer 1 is thermosetting the material is heated after bending for final curing.

Abstract: 1,105,259. Automatic voltage control. GOERZ ELECTRO G. m. b. H. Nov. 2, 1965 [Dec.10, 1964], No.46395/65. Heading G3R. A voltage regulator comprises transistor Tr1 and Tr2 connected in series between input and output terminals; transistor Tr1 is controlled in dependence upon output voltage variations by a conventional control circuit D, V; the base of transistor Tr2 is connected over a resistor R2 to its collector, and over a diode D2 to the negative terminal of an auxiliary voltage source UH having its positive terminal connected to the emitter of transistor Tr1. The values of the components and the voltages are so chosen that transistor Tr2 is short-circuited while transistor Tr1 exercises the control function until the voltage across it reaches a maximum permissible value; if the voltage across the series transistors then increases further, diode D conducts and the base of transistor Tr2 assumes the negative potential of source UH. The further increase in voltage is then taken up across transistor Tr2, the voltage across Tr1 remaining at the maximum permissible value whereby the latter transistor is protected against excess voltages. A modification using three series transistors is described with reference to Fig. 4 (not shown).
