Abstract: 721,926. Wind motors. FAUVEL, A. F. J. M. Aug. 28,1952 [Sept. 5,1951; Jan. 2, 1952], No. 21671/52. Class 110 (3). A wind-motor plant comprises one or more bladed rotors located in one or more adjacent tunnels having divergent ends which open into two opposed common collectors bounded by the ground and two divergent walls and partially covered from the tunnel ends outwardly by a hood which diverges vertically with respect to the ground. The plant shown comprises a plurality of adjacent convergent divergent tunnels 1 to 10 in the narrower zones of which are located bladed rotors 11 to 20. The assembly of tunnels is connected at either end to a pair of divergent collectors 21, 22, the angle of divergence of which is greater than that of the tunnels. Each collector comprises a pair of lateral walls 23, 24 which extend a distance D which may be up to twenty times the length of the tunnels land which are partially covered by a hood 25 extending over a distance d which may be as great as five times the tunnel length. One of the portions of the tunnel 26, Fig. 2, has its inner end debouching on the lower portion of the rotor 15 while the other portion 28 leads to the upper portion of the rotor. Two pairs of retractable deflectors 29, 29a and 30, 30a are provided so that the rotor may be caused to rotate in the same direction despite the direction of the wind. Movable shutters 31 to 40 and 41 to 50 are provided in the hood and are opened when they are located on the leeward side of the rotor. Each tunnel may be closed at either end by means of gates 51 to 60 and 61 to 70. These gates may close the tunnel either partially or totally on the inlet side so as to adjust the velocity of flow in the tunnels. The lateral walls 23, '24 are provided with discharge gates 71, 72 which are opened when the wind'velocity exceeds a a predetermined limit. The deflectors, discharge 'shutters, tunnel gates and discharge gates of the collectors are controlled automatically by a device responsive to wind speed and direction. Each of the rotors consists of a cylinder 73, Fig. 6, formed by a metal frame covered with stainless sheet steel elements, on which are mounted triangular-sectioned blades 74. A gear wheel 77 on the side of the rotor meshes a pinion 78 driving a machine 80. The rotors may be arranged with their axes either horizontal or vertical. A number of rotors may be arranged in series in each tunnel. A modification in which the collectors are formed by portions of frusto-conical surfaces is described. In this arrangement, a retractable deflector is arranged in front of the hoods to protect the hoods during a gale. These deflectors are formed of oilcloth reinforced by wire netting which may be wound on to vertical posts when they are not required. Details of the construction of the walls, deflectors, discharge shutters, tunnel gates and discharge gates are also given.

Title: Process for preparing crystallizable and crystalline polymers
IPC: C08F20/42
Filed: 1958-07-09
Abstract: Crystallizable and crystalline polymers are prepared by a method which comprises mixing monomeric tertiary butyl acrylate or tertiary butyl methacrylate with a catalyst system comprising lithium metal in a finely dispersed condition having a particle size not exceeding 200 microns, in amounts of 0,01 to 5% based on the weight of monomer, and polymerizing said mixture in an inert atmosphere.  Polymerization may be effected in solvents unfavourable to ionization, e.g. hexane, heptane, octane, Varsol, mineral spirits, petroleum and kerosene. Amorphous polymer may be separated from the product by extraction with a solvent, e.g. acetone, which may contain alcohol to destroy catalyst residues. The products may be hydrolysed to crystallizable polyacrylic or polymethacrylic acid which may be esterified, e.g. with n-butyl alcohol in the presence of sulphonic or p-toluene sulphonic acid; or the products may be transesterified.  The products may be employed as adhesives, in moulding and laminating compositions, fibre forming, wool, cotton, linen and nylon textiles, paper, paper pulp, wood and leather.

Abstract: 722,229. Peat-cutting machines. BJORKLUND, G. Sept. 2, 1952, No. 22050/52. Class 68(1). A peat-cutting machine comprises a wheeled carriage running on rails, a frame 16-25 movable up and down between two vertical guides 14, 15 on the carriage, and a U-shaped knife 45 protruding horizontally at one side of the frame to cut out a peat column during the downward movement of the frame. Also mounted to reciprocate horizontally in the frame is a second frame 34, 35, 42, the part 42 being provided with a number of horizontal knives 47. The second frame, during the downward movement of the first frame is withdrawn clear of the peat column against the action of springs 32 by a roller 36 on the second frame moving along a cam rail 33 until, when the first carriage has reached the lowest position, the roller 36 clears the rail 33 and the second carriage is urged by the springs 32 towards the peat column so that the knives 47 slice up the column. As the first carriage rises, carrying upwards the second carriage and the detached peat, the roller 36 runs up a guide 14 and, at the uppermost position of the first carriage, passes through a pivoted flap 38 in the rail 33 ; the cycle of operations can be repeated. Between each pair of cutters 47 is mounted, on a rod 49, a shovel 48. The rod 49 passes through a horizontal slot in the plate 42 and has mounted on the free end a roller 51 and, adjacent the plate, a slide 50 that can move along guides 52 secured to the plate 42. As the first and second frames rise each roller 57, in turn, engages one side of a fixed cam rail 53 to cause first the shovel to move to discharge the peat onto a conveyer and then the other side of the cam rail to return the shovel. The machine is advanced by a pawl and ratchet mechanism actuated by the movement of the first carriage which is caused to oscillate by being connected by a pin to a chain 9 passing over a driven pulley 8 and an idler pulley 10.

The bis-amide may be partially imidised and the preferred excess in step (ii) is 1.4 to 1.6 mol %. The procedure is stated to allow a suitable molecular weight for coating purposes (e.g. an inherent viscosity of 0.8 to 0.9 at 0.5g/dl in N-methyl pyrrolidone at 37.8‹C) to be obtained with a narrow molecular weight distribution. The final product is preferably amine terminated and route (ii) (a) is therefore preferred to (ii) (b) and an amine is desirably used to end cap the final product. The final product may be reacted with a nitrogen base to give a watersoluble product. Extensive lists of suitable dianhydrides, diamines, solvents and nitrogen bases are given. In Examples the reactants are 3, 3', 4, 4'-benzophenonetetracarboxylic dianhydride and 4, 4'-diaminodiphenyl methane and ether, the solvent is N-methyl pyrrolidone and the nitrogen base (when used) is NH 4 OH. Some Examples incorporate a surfactant which is carboxypropyl terminated dimethyl siloxane for organic solution and a non-ionic nonyl phenolethylene oxide adduct for aqueous solutions. Uses. The Examples illustrate the use of both the organic and aqueous solutions as insulating enamels for copper magnet wire in a conventional wire tower. They are stated to be useful for all high-temperature insulation applications, e.g. stator and rotor slot insulators, transformers, cable casings, capacitors and various laminating processes.
