Abstract: 405,926. Harvesting root crops. WILKE, O., Harber, Hohenhameln, Germany. Oct. 4, 1933, Nos. 27297 and 27298. Convention dates, Oct. 7, 1932 and Nov. 25, 1932. [Class 6 (iii).] In a machine for harvesting root crops, such as beet roots, a feeler roller, comprising a number of discs 1-4, with teeth or p'ns projecting from their peripheries, mounted on a rotating shaft 6, is arranged to engage and penetrate the leaves of the roots the teeth passing between the leaves and entering for a short distance into the head of the root. The roller is driven through sprocket gear from the main driving shaft 12 at a speed a little greater than the speed of travel of the machine. A topping knife 14 having sole pieces 13 and adjustable vertically and horizontally relatively to the feeler roller is arranged behind the roller and with it and its associated mechanism is mounted on an auxiliary frame 15 which can swing about a pivot 16 and is supported at its forward end by a spring 17 the tension of which may be adjusted by a screw 18. The cut off tops are detached from the feeler roller by a removing roller, consisting of a number of toothed discs 19-23 that penetrate between the discs of the feeler roller, that delivers them between the two endless bands 24, 25 of a conveyer which carries them to a transverse conveyer 36 by which they are delivered to a discharge hopper 26 the outlet of which is controlled by a lever 27. The auxiliary frame 15 may be moved bodily laterally on its pivot 16. In a modification the removing roller is dispensed with, the upper band of the conveyer being provided with teeth to remove the tops from the feeler roller. The lifting tines 49 with their associated parts are carried by an auxiliary frame that is supported by rollers 53 on the front beam 54 of the frame and can slide on the rear transverse beam 55 thus being capable of lateral adjustment : a lever 56 is preferably provided to move the cutting frame and the uprooting frame simultaneously. The roots slide up the tines 49 into a skeleton basket 40 from which they are thrown by beating members 41 on to a conveyer 44 by which they are carried to a hopper 60. A soil smoothing member may be fitted behind the uprooting tines. The lefthand side of the machine frame may be arranged for vertical adjustment relatively to the wheel axle.

Title: Improvements in or relating to engines having gas compressors
Inventor: MURRAY FREDERICK REGINALD
IPC: F01D9/04
Filed: 1958-09-01
Abstract: 911,160. Gas-turbine plant; axial-flow compressors. ROLLS-ROYCE Ltd. Aug. 31, 1959 [Sept. 1, 1958], No. 28072/58. Classes 110 (1) and 110 (3). In an engine having a compressor which has an annular working fluid channel in which the compressed gas flows, a pair of collector manifolds are respectively positioned radially outside and radially inside the annular channel and communicate with the interior of the annular channel through porting in the outer and inner walls of the latter, the manifolds being interconnected by hollow vanes extending across the annular channel between the walls. In the gas-turbine engine shown, an axial-flow compressor 10 supplies air to combustion equipment by way of a working fluid channel formed between annular walls 18, 19. Air for auxiliary purposes is tapped from the compressor through annular ports 25, 26 and diffuser passages 27, 28, formed between conical flanges 21, 22 on the walls 18, 19 and conical flanges 23, 24 on the air casing walls 16, 17 of the conbustion equipment. The diffusers lead to manifolds 29, 31. The air entering manifold 29 is conveyed to manifold 31 through hollow aerofoil guide vanes 20. To avoid undesirable reduction of flow area of the working fluid passage due to the vanes 20, the walls 18, 19 are curved in axial section, as shown, so as to have a maximum spacing in the plane of the maximum thickness of the vanes. Circumferentially-spaced struts 37 extend between the walls 18, 19 and flanged rings 35, 36, and this structure is supported from the compressor casing by means of a thick ring 40 having an end plate 40a for locating the structure axially. Circumferential location of the structure is provided by radially-extending teeth 40c which engage corresponding teeth on an annular plate 46 secured to the ring 35. This arrangement allows for radial expansion. A bearing 34 is supported from the structure by means of a diaphragm 33 bolted to the ring 36.

Patent GB-390861-A (GB)
Title: Improvements in or relating to the treatment of textile materials with liquids
IPC: D01D5/04
Filed: 1931-10-12
Abstract: Liquid is applied to filaments, yarns, threads, and ribbons by passing them over a circumferentially grooved roller supplied with liquid, the roller being of light construction and mounted in a substantially frictionless manner so that it is rotated by the filaments passing over it, and offers little resistance to the passage of the filaments.  The process is of particular use in the application of liquids to artificial filaments during their manufacture before they have reached a fully set and finished condition.  Preferably, the roller is made of light material such as aluminium, vulcanized rubber, and synthetic resins.  The roller may be die-cast or machined.  The depth of the groove affords a measure of control over the amount of liquid to be applied to the thread. The roller may be used to apply water, lubricant, sizes or softening agents.  It may be employed in processes of washing filaments of cellulose acetate or other cellulose derivative after their emergence from a coagulating bath, or for applying softening agent in processes for combining a number of filaments to form straws, or filaments of large cross section, or for applying or removing softening agent in a stretching operation, or for removing high boiling point solvents from dry spun threads.  As shown in Fig. 1, filaments 12 issue from a jet 11 and pass in contact with and rotate a grooved roller 16 mounted within the spinning cell and dipping into a liquid 20 contained in trough 21. The filaments pass down the cell and then out to a winding device 15.  A further liquid-applying roller 22 is situated outside the spinning cell in contact with, and rotated by the filaments.  A liquid-applying roller 16 is shown on a larger scale in Fig. 5. It is mounted in pivot bearings formed by the conical ends of bolts 18 which engage <PICT:0390861/IV/1> conical a pertures in the axis of the roller.  The amount of liquid applied to the threads may be controlled by adjusting the roller so as to vary the area of surface contact of the thread and the roller or by changing the roller for one having a groove of different size.  As shown in Fig. 4, a number of rollers 140 are mounted on a common shaft 41 and apply liquid to threads which are passed in contact with the grooves 17.  The rollers may be mounted loosely on the shaft or they may be secured so as to rotate together.  As shown in Fig. 6, filaments 49 issue from a nozzle 48 into a coagulating bath and after emergence are led over the roller 51 which is rotated by the thread and which applies washing or neutralizing liquid to the thread.  The thread then passes over a fluted or roughened godet 54 to a centrifugal box 55. Specifications 182,166, 312,203, 326,462, 327,740, 328,312, 333,926, 334,838, 334,853, [all in Class 2 (ii), Cellulose &c.], 340,324, 340,325, 340,326, 340,436, 340,437, 343,062, 353,956, 355,652, 358,500, 378,074, and 390,860 are referred to.

Patent GB-809484-A (GB)
Title: Polyethylene compositions
IPC: C08L23/06
Filed: 1956-09-17
Abstract: A composition comprising a major proportion of polyethylene and from 25 to 40 weight per cent based on the total composition of a polyisoolefine of molecular weight above 140,000, is extruded as a tubular membrane to form a flexible, shrinkable container for meat or other foodstuffs.  The polyiso-olefine is prepared by polymerizing an iso-olefine, e.g. isobutylene containing 4 or 5 carbon atoms per molecule, in the presence of a solution of a Friedel-Crafts catalyst at a temperature between - 40 DEG  and - 150 DEG  C. may contain up to 10 weight per cent of a low molecular weight copolymer of an iso-olefine and a vinyl aromatic hydrocarbon, e.g. styrene, which has an intrinsic viscosity below 0.5.  The copolymer is prepared by polymerizing 40-70 weight per cent of a polymerizable mono-olefinic aromatic hydrocarbon with an iso-olefine containing 3 to 8 carbon atoms per molecule in the presence of a Friedel Crafts catalyst, at a temperature between - 10 DEG  and - 100 DEG  C.  The composition is prepared by homogenizing the polyiso-olefine and polyethylene in a blender, removing a portion and replacing it with an equivalent amount of polyethylene to give the desired blend which may then be extruded as a tubular film at 250 DEG  F.  In examples, compositions of 70 per cent polyethylene, 27 per cent polyisobutylene of 300,000 and 200,000 MW's, and 3 per cent of a copolymer of isobutylene and styrene containing 60 per cent styrene, with an intrinsic viscosity below 0.5, are prepared and show a shrinkage of up to 15 per cent. The containers formed from extruded film are nontacky, pliable, deformable and impermeable to water, and may be stretched to remain extended at room temperature and to shrink when heated to 200-212 DEG F.
