Title: Improvements primarily connected with hedge cutting apparatus
IPC: A01G3/04
Filed: 1957-08-13
Abstract: 864,901. Hedge-cutters. LEE, W. S. K. Aug. 11, 1958 [Aug. 13, 1957], No. 25467/57. Class 6(2). Means for mounting a hedge-cutter on a tractor comprise an intermediate frame 5 connected to the lift arms of the tractor, and a boom-supporting frame 8, the two frames 5 and 8 being pivotally connected by side frames 9 and 10 to constitute a parallel motion linkage capable of angular movement in a horizontal plane by the operation of a singleacting hydraulic ram 11 which is in communication with the hydraulic system of the tractor. As shown in Figs. 2 and 3, a spring 12 is provided for cancelling the action of the ram 11, the spring also allowing the boom to move away from the hedge on encountering an obstruction, but alternatively a double-acting ram may be incorporated in the linkage system. The boom 15 supporting the hedgecutter 20 is mounted by means of the bracket 16 so as to pivot about the axis of the driving shaft 17, such pivotal movement, and therefore adjustment of the height of the hedgecutter 20, being effected by adjustment of the strut 14. The hedge-cutter 20 is mounted so that its position relative to the boom is adjustable about a horizontal axis, such adjustment being effected by means of the hand-operated worm and wheel arrangement 22. Drive to the cutter is transmitted from the power take-off of the tractor via the universal joints 28, shaft- 17, gearing 18, and shaft 19. The mounting of the boom is stabilized by the provision of a triangular frame 23 and strut 24. Mention is made in the Specification of the provision of weights to counter balance the weight of the boom.

Title: Process and apparatus for producing synthesis gas
IPC: C01B3/48
Filed: 1952-10-10
Abstract: <PICT:0737394/III/1> In a process for producing synthetis gas from gaseous hydrocarbons or gases containing them, in particular from methane-containing gases, by reaction with oxygen or an air-oxygen mixture the formation of soot is inhibited by recycling to the gas to be cracked, cracked hydrocarbon gas or synthesis gas and the reaction is effected without precombustion, with starting gases which are not supersaturated with water vapour and are preferably cold, in a single stage using conventional catalysts at an elevated temperature.  The gases are preferably cooled before entering the chamber containing the catalyst and the arrangement for the supply of the reactant gases to the reaction chamber is such that the speed of flow of the oxygen or air-oxygen mixture alone in the feed duct to the reaction chamber is maintained above the maximum ignition velocity of hydrocarbon and recycled gas with oxygen or air-oxygen mixture.  In the apparatus shown in Fig. 1 a mixer 1 is supplied with desired amounts of oxygen at 2 and air at 3 and the resulting air-oxygen mixture is mixed in a mixer 4 with hydrocarbon containing and recycled cracked or synthesis gas supplied at 5.  The reactant mixture passes through tubes 15 which have a cross-sectional area chosen to ensure that the velocity of the gases flowing through the tubes is always greater than the p maximum ignition velocity of the reactant mixture and which are cooled externally by water entering at 13 and leaving at 14.  The tubes 15 are interrupted at intervals so that the gases pass through perforated baffle plates 7 and 8, other sets of baffle plates are provided at 5 and 9.  The reactant mixture enters the reaction chamber 16 through a grate 19 which also has a water-cooled tube system, the cross-sectional area of the tubes being such as to ensure the required minimum flow velocity.  The grate 19 supports fireclay bodies 17 and a bed of catalyst 18.  In a modification the mixer 4 is omitted and the grate 19 is designed as a mixer for the air-oxygen mixture and the hydrocarbon and recycled gases.  In a further modification apparatus described provides a second reaction chamber in which the cracked gases from the first reaction chamber are, after cooling from about 800-900 DEG  C. to about 400 DEG  C. and in the presence of steam reacted to convert the carbon monoxide and steam into carbon dioxide and hydrogen with the use of known catalysts. Specification 616,710 is referred to.

Title: Electrolytic process and apparatus for gas purification
Inventor: MAGET HENRY JEAN ROBERT
IPC: C25B9/19
Filed: 1965-06-16
Abstract: A process of treating gases comprises (1) feeding a gaseous composition containing the gas to be treated to a first catalytic electrode in contact with an electrolyte which also contacts a second catalytic electrode, each electrode being electrically conducting and capable of absorbing the gas to be treated and the electrolyte being an ion exchange resin, (2) applying D. C. potential between the electrodes whereby a reaction occurs at each electrode and is catalyzed by the material of which the electrode is made, the reaction resulting in the ionic transport of the gas or a component thereof through the cell, and (3) removing the treated gas from the second electrode.  The treatment may result in removing a selected component, e.g. hydrogen or oxygen, from a gas mixture, providing treated gas at a higher pressure than the gaseous composition e.g. compressing a gas, or changing the concentration of a component in a gas mixture.  Purified gas from a mixture may be fed to a fuel cell in the same casing in the electrolysis unit, the electrolysis gas removal chamber and the fuel cell input chamber being the same space. In examples for extracting hydrogen from a gas mixture or for increasing the pressure of oxygen, there are used Pt black electrodes and a solid electrolyte formed by a sulphonated phenolformaldehyde resin. Other electrode materials referred to are Rh, Pd, Ir, Pt, Ni, Cu; Pt or Pd blacks deposited on a base of stainless steel, iron or nickel; metal oxides; carbon activated with Pt, Pd or oxides of Fe, Co, or Mg; or alloys of a noble metal, Ti and Ta.  Other ion-exchange resins referred to are polystyrene-divinyl benzene sulphonic acid copolymers and phenol-aldehyde carboxylic acid copolymers (cationic) and quaternized chloromethylated polystyrene and aminated chloromethylated polystyrene (anionic).

Title: Improvements relating to the compounding of rubbers and of synthetic resins
Inventor: SAUL WALTER
IPC: C08L95/00
Filed: 1956-08-23
Abstract: Non-coherent compositions are made by distributing (see below) through the particles of a filler, a rubber in finely-divided form or a thermoplastic synthetic resin in finely-divided form, and also a liquid plasticizer for the rubber or resin, and subsequently heating the mixture to a temperature sufficient to cause at least a part of the plasticizer to be absorbed by the rubber or resin, and at least a part of the rubber or resin to be attached to the particles of the filler, without agglomeration of the mass.  By "distributing" is meant intermingling the rubber or resin and plasticizer relatively lightly, e.g. in a paddle mixer, as opposed to intermixing by such forcible methods as grinding.  The filler may be a fibrous filler such as wool, cotton, asbestos, glass wool, slag wool or regenerated cellulose, or a non-fibrous filler such as limestone, whiting, slate dust, brick dust, finely-divided nut-shells, sawdust or road-aggregates such as granite and quartz.  The resin may be polyvinyl chloride, a copolymer of vinyl chloride with vinyl acetate, vinylidene chloride or ethyl acrylate, polyvinyl acetate, polyvinylidene chloride, or a terpolymer derived from the monomers of these polymers.  The rubber may be a butadiene-acrylonitrile or butadienemethyl isopropenyl ketone copolymer, neoprene or a rubber-like chlorosulphonated polyethylene or polypropylene.  The plasticizer may be dibutyl, dihexyl or dioctyl phthalate, or tricresyl or trichlorphenyl phosphate.  The non-coherent compositions may be converted to coherent compositions by moulding or calendering to produce, e.g. floor tiles; they may be converted into surfacings for, e.g. airfield runways, roads and p  railway-station platforms by mixing with tar and an aggregate, or into joint-filling materials by mixing with tar and a filler; they may be extruded to form, e.g. flooring blocks, or used as impregnating agents for felt and textile fabrics, as cements or as coatings for metals, wood, rubber and synthetic resins, particularly on pipes.  Specifications 581,368, 737,022, 770,067, 827,847, 850,364 and 853,525 are referred to.

IPC: H01J29/00
Filed: 1951-11-07
Abstract: 716,627. Television pick-up tubes. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Oct. 27, 1952 [Nov. 7, 1951], No. 26018/51. Class 39(1) In a television or similar pick-up tube in which an electron image is focused on to a charge storage target which is scanned by an electron beam, the effect of spiral distortion of the electron image is compensated by setting up on the side of the scanning coils remote from the target, a magnetic field which penetrates the scanning coils so as to cause the scanning beam to scan the target in a spirally distorted manner, the scanned area being spirally distorted in the same sense as the electron image. The compensating magnetic field does not disturb the electron image focusing field. As shown for a pick-up tube in which the scanning beam is projected on to the front of the target at an oblique angle, the compensating coil 8 acts also as a focusing coil for the scanning beam, or a separate focusing coil may be provided. Residual distortion can be compensated by adjustment of the scanning wave forms applied to the scanning coils 7. The scanning coils are enclosed by a screen, of high magnetic permeability, formed as two telescoping parts 19, 20, Fig. 2. The coil 8 is wound on annular former, and is encased by a magnetic yoke composed of two mild steel members 9, 10 shaped to provide annular pole pieces 11, 12. The coil assembly 8 is mounted on a brass sleeve 15. The sleeve 15 and the scanning coil assembly 7 are mounted on an insulating former 18. The coil 8 and scanning coils are spaced apart by means of three angularly spaced distance members 21. The focusing field for the electron image may be produced by a coil or by a permanent magnet structure. A permanent magnet structure may be used for focusing the scanning field. The pick-up tube may be of the kind in which the scanning beam is projected on to the back of the target.
