Title: Improvements in or relating to devices for the lateral displacement of crop lying on the ground
IPC: A01B63/02
Filed: 1965-08-13
Abstract: 1,117,122. Haymaking machines. TEXAS INDUSTRIES Inc. 13 Aug., 1965 [11 Sept., 1964], No. 34879/65. Heading A1F. A haymaking machine comprises a tractor-mounted frame 1 upon which are mounted two groups of rake-wheels 23, 26 one group 26 being mounted on a subframe 11, 14 which is movable laterally on parallel links 7, 8 whereby the two rakewheel groups can operate upon alternate swaths F, H, leaving an intermediate swath G unworked, or can be moved close together so that the device operates as a normal swath-turner and works adjacent swaths. The invention envisages a method of working wherein two runs of the machine are made in opposite directions, during swath-collecting, so that, in the first run, crop from swaths F, H is deposited upon the crop in adjacent swaths E, G; the next run, in the opposite direction, results in all the crop in the unworked swaths G, E being aggregated into two large windrows in place of the four swaths E, F, G. H existing previously.

Abstract: 929,917. Shearing. MOELLER & NEUMANN G.m.b.H. Sept. 29, 1961 [Oct. 7, 1960], No. 35174/61. Addition to 922,563. Class 83 (4). The invention described in the parent Specification which comprises a shear having a stationary bottom cutter and a top cutter movable in an arcuate path during cutting and which is fastened to a rocking member supported on a spindle parallel to the cut, wherein the spindle is movable away from the cut edge of the plate before the return stroke of the top cutter, is modified in that several rocking members are assembled to form a drum-like top cutter carrier which is mounted for free rotation and in that a reciprocating cutter drive is adapted to exert leverage on the carrier relatively to the spindle at several points corresponding to the number of rocking members, or of top cutters. The cutter carrier comprises a drum 2 mounted on a spindle 3 and carries four cutters 1. Associated with each cutter is a semicircular socket 6 which receives the end of a plunger 7 which is driven by an eccentric 8 on a crank-shaft 9. The plunger 7 is attached to the drum by two removable pins, to effect the return stroke of the cutter. A cutter is used until it is worn, and a new cutter is then brought into position by disconnecting the plunger 7, rotating the drum 90 degrees and re-connecting the plunger. In order to move the top cutter away from the bottom cutter during the return stroke the bearings of the spindle 3 are mounted in blocks which slide in guides 24 and 25 and are controlled by a toggle linkage which comprises links 17 and 18 and a double-acting hydraulic cylinder 22.

The resilient material is preferably plastics sheet material, e.g. polystyrene, and the limp material may be paper, card, metal foil, plastics film, or composites thereof. An anti-theft device may be included in the tag in the form of a strip 10, Fig. 3, of metallized foil inserted between sheets 8, 9. A fracture line 11 is provided in the second portion 3 and so long as the strip remains unsevered from the tag, the package it is attached to may be detected by electronic alarm systems. The line may be a score line or a partial severing and the detachable portion is narrow to prevent detachment by hand. Manufacture.-The tags are manufactured by passing polystyrene sheet stock 15 from a supply roll 16 through an intermittent feeding device 17. A self-adhesive paper strip 18 is applied to the surface of the stock 15 from a supply reel 19 backed by a release-paper backing 20. The strip 10 can be applied as a continuous self adhesive thread on the stock prior to application of the paper strip 18. The strip and stock are fed together into a die-punch 12 where the tags are punched out as a continuous strip. The resilient layer may conform to the whole of the limp material sheet or only the first portion.

Filed: 1928-11-29
Abstract: 324,467. Horner, G. W. Nov. 29, 1928. Stoppers, screw ; packing-discs.-A closure for bottles &c. comprises an outer cap secured over the orifice of the bottle and adapted to cover entirely a sealing medium applied across the orifice, the sealing medium being spaced from the cap by a ring-like member and formed of such material that increased pressure in the receptacle causes it to resume a curved or belled form with the whole of its periphery in firm sealing engagement with the edge of the orifice. A disc 2, preferably backed by a metal disc 3, engages a ring-like depression 8, of smaller diameter than the mouth, formed in the screw cap 5 of the closure; increased pressure in the bottle acts directly on the packing disc to cause it to fulcrum about the ring 8 and engage the bottle mouth more tightly. A separate ring may replace the depression 8 or the ring may be integral with the disc 3.

Title: Improvements in or relating to cathode-ray tubes for colour television
IPC: H04N9/26
Filed: 1957-11-12
Abstract: 864,796. Colour television tubes. PHILIPS ELECTRICAL INDUSTRIES Ltd. Nov. 12, 1957 [Nov. 15, 1956], No. 35236/57. Class 39(1). A television reproducing cathode ray tube comprises a gun, a three colour stripe fluorescent screen and two interleaved colour switching grids each grid having straight wires parallel to the phosphor stripes, each grid being flat or cylindrically curved and the grid wires each having a thickness varying along its length from the centre to each end and this variation, the shape of the grids and the shape of the screen being so related as to make the spot displacement sensitivity more equal over different areas of the screen. The colour switching grids also effect beam focusing. It is explained that the deflection sensitivity increases. from the centre to the edges of the screen if screen and grid are flat and parallel. If then the grid wires lie in a cylindrical surface and are thicker at their centres that at their ends according to. the invention concave to the screen and the screen is flat then deflection sensitivity compensation is achieved in a direction at right angles to the grid wires and the grid wires are thicker at the centre than at the ends. (Fig. 1 not shown). To get compensation in a direction along the grid wires the screen can be made cylindrically concave towards the grid in a plane at right angles to the concavity of the grid but this reduces the compensation effect of the grid in the direction at right angles to the grid wires. If the grids are flat and the screen spherical the tube face plate in general has a curvature different from the screen so unwanted reflections are liable to occur while if the screen is a coating on the tube face plate overcompensation of the deflection sensitivity occurs. The grids may be cylindrical and convex to the spherically curved screen and the grid wires thinner in the centre and thicker at the ends, Fig. 2. The grid wires lie in a cylindrical convex plane of a larger radius of curvature than the screen and the face plate 2 and fluorescent screen coating 4 thereon are spherical. The grids can be made by winding, then immersing in an etching or plating bath for half their length and drawing them gradually upwards, then reversing them and treating the other half in the same manner. In the case in which they are plated the variation in thickness of each grid wire can be made linear or non-linear by controlling the rate of withdrawal and for the current intensity in the plating bath. In Fig. 2 the variation in thickness of the grid wires is chosen to correct the over compensation of the deflection sensitivity due to the screen and grid being relatively closer at the edges than in Fig. 7 (not shown).
