Title: Machine for the cultivation of row crops, especially for singling plants by means ofa thinning tool, controlled by a photo-electric cell
IPC: A01B41/06
Filed: 1962-11-24
Abstract: 1,012,490. Agricultural implements. FRANZ KLEINE MASCHINENFABRIK Nov. 24, 1962, No. 44519/62. Heading A1B. A machine for thinning out plant rows comprises blades 6, 7 attached to a lever 9 moved transversely of the row under the control of a photo-electric cell 4, 5. A further lever 13 supports a plate 16 journalled on shaft 15 and having on its upper side a helical cam track 17, the shaft 15 carrying a bevel gear 18 engageable with a gear 19 on shaft 20 driven by the land wheel of the machine. The lever 9 carries a roller 25 for engagement with the cam track 17, and a roller 26 co-operating with lever 28, 29 to arrest the lever 9 in its initial position shown dotted in Fig. 1. When the beam of cell 4, 5 is interrupted by a plant knife 7 is moved into the row. Further forward movement of the machine causes plate 16 to rotate the cam track 17 forcing roller 25 to the outside of the plate 16 and moving lever 9 into its initial position, where it abuts against contact 33 to close the circuit to an electromagnet 30 which attracts lever 28, 29 which pivots so that it bears against roller 26 to hold the lever 9 in its initial position. Immediately the end of track 17 passes beneath roller 25, an inclined guide 36 on plate 16 engages roller 25 resulting in 'lever 13 moving aside so that gear 18 separates from gear 19 and plate 16 stops. When the cell beam strikes the next plant to be singled, the cell 5 interrupts the magnet circuit so that lever 29, 28 is released, thereby releasing lever 9 which moves under the action of spring 39 to bring the knives 6, 7 into the row, the lever 13 at the same time moving to bring gear 18 into contact with gear 19 to rotate plate 16. In a modification the blades are carried by a lever which is held in its initial position outside the row under the control of an electromagnet.

Title: Process for manufacturing a flexible tube from thermosetting resin and inorganic particles
IPC: B29C41/08
Filed: 1972-03-24
Abstract: 1391777 Moulding tubes INDUSTRIELE ONDERNEMING WAVIN NV 24 March 1972 [29 April 1971] 44591/71 Heading B5A [Also in Division F2] A tube comprising an inner layer of fibrereinforced thermosetting resin, an intermediate layer of inorganic particles with less than 40% by volume of thermosetting resin and an outer layer, which e.g. may be of impregnated fibre fleece and may be reinforced with rovings impregnated with thermosetting resin, is made by a method in which the inner layer is formed on a mandrel and the intermediate layer is sprayed on to the inner layer as the mandrel rotates by allowing the inorganic particles to fall adjacent the mandrel and directing an atomized jet or spray of thermosetting resin into them to combine with them and carry them on to the surface of the inner layer to which the mixture adheres. When a sufficient thickness of resin/powder layer has been formed in this way a web of, e.g. glassfibre fleece or polyester fibre fabric is wrapped around under sufficient tension to compress and consolidate the intermediate layer. The inner layer may, e.g. be a band of glass rovings impregnated with a polyester or epoxy resin or a mixture of resins. The inorganic particles may be of sand and are preferably heat dried and graded in a size range from 0À1 to 3 mm.; they may alternatively be of skimmed clay. The resin is sprayed with pressure preferably between 5 and 200 atmospheres according to viscosity and a two components jet of resin with catalyst and resin with initiator may be used; the resin may be cold hardening. Examples indicate suitable dimensions and proportions for the various comonents but the preferred proportion of resin for the intermediate layer is 14 to 18% by volume, although it may be as low as 5%. It is stated that the covering layer may be a non-reinforced layer of thermosetting resin or a thermoplastic material.

Filed: 1960-12-30
Abstract: 943,748. Blow-moulding hollow articles. BROCKWAY GLASS CO. Inc. Dec. 30, 1960, No. 44880/60. Heading B5A. A tube of thermoplastic material is extruded downwardly from a chamber 22 having an orifice 26 and a central core comprising a fixed sleeve 28, a concentric sleeve 30, a degating sleeve 32 and a blow tube 34, the sleeves 30, 32 and blow tube 34 being slidable to control the extrusion process. The degating sleeve 32 is protected from thermoplastic material which oozes back between the parts 30 and 32 by a sleeve 40. In operation, with the parts set as in Fig. 2, the extruded tube is that part intended to form the body of the container. After extrusion of a suitable length the degating sleeve is moved slightly downwards so that a thinner tube is extruded which will form the shoulders of the blown article, and finally the blow tube 34 is moved to the position shown in Fig. 6 when the " false neck " part of the tube is extruded, this being later removed from the blown article. Then the degating sleeve 32 is moved downwardly to cut off the extruded tube as in Fig. 6 and the mould parts 51, 52 are closed about the tube to pinch its bottom end. Blowing air is supplied to the blow tube 34 to form the article in the mould, the mould being then opened leaving the article suspended on the blow tube, which is then retracted to remove it. The frusto-conical end of the control sleeve may be irregular so that the extruded tube may be thicker at some points than others, and this may be retracted after extrusion of the " body portion " in order to extrude a circular portion for the neck of the article. An alternative form of nozzle is shown in Fig. 10 where the thickness of the extruded tube may be controlled by the sleeve 80 without complete retraction of the degating sleeve 81 to give a better inside finish to the tube. In the case where articles with a thin neck portion are required, the resultant use of a thin degating sleeve gives a poor inside finish and this is overcome by the arrangement shown in Fig. 10 where the extrusion occurs between the orifice 77 and the bevelled end of the blow tube 82. Specification 932,967 is referred to.
