Title: Improvements in the production of carboxylic acids and their anhydrides
IPC: C07C51/14
Filed: 1952-04-24
Abstract: Carboxylic acids and their anhydrides are made by treating olefins with carbon monoxide and water or carboxylic acids at elevated temperatures and pressures in the presence of a complex nickel compound containing an organic substituted tertiary amine and/or an organic substituted tertiary phosphine in complex combination.  The catalysts may be derived from nickel salts of organic acids such as acetic, propionic or valeric acid and are preferably of the acid whose formation is desired, or they may be derived from nickel halides, cyanide or thiocyanate.  Nickel carbonyls wherein one or more CO- group is replaced by the amine or phosphine may also be used.  Tertiary amines and phosphines mentioned include pyridine, trialkylamines, tetraalkyl diamino alkanes, and benzyl methyl aniline, and trialkyl, triaralky and triaryl phosphines such as tri-isobutyl, tribenzyl or tritolyl phosphine.  The amines may contain ether oxygen.  Mixtures of the catalysts may be used.  The catalysts may be added at the commencement of the reaction, after preparation by heating the constituents together, or formed in situ by adding the catalytic ingredients to the starting mixture.  Liquid phase operation is preferred.  Temperatures specified are 180-300 DEG C.  The pressure preferably exceeds 50 atmos. and is preferably 150-300 atmos. Solvents, e.g. saturated hydrocarbons, esters, lactones or the reaction products may be present.  The olefinic charge may contain saturated hydrocarbons.

Title: Vehicle for travelling over land and/or water
Inventor: COCKERELL CHRISTOPHER SYDNEY
IPC: B60V1/00
Filed: 1959-03-26
Abstract: 946,917. Air cushion vehicles. HOVERCRAFT DEVELOPMENT Ltd. March 21, 1960 [March 26, 1959], No. 10543/59. Heading B7K. A vehicle for travelling over a surface and which in operation is supported above the surface by at least one cushion of pressurized gas formed and contained beneath the vehicle, the cushion being contained for at least part of its periphery by a curtain of moving fluid issuing from the lower part of the vehicle includes means distributed along said part of the periphery for supplying further fluid to the region of the cushion immediately inboard of and adjacent to the position from which the curtain of moving fluid issues. The vehicle comprises a main body 1 and a base portion 2 and air is drawn through an intake 3 by an engine-driven propeller 4 and delivered via a duct 7 to a chamber 8 formed in base 2, from which it passes through ducts 9 and 10 to two annular ports 11 and 12 formed in the bottom of the vehicle. Once a supporting cushion has been formed, the cushion pressure will deflect the air curtains from ports 11 and 12 so that they follow a curved path outwards. The flow of air from the ports causes a flow of entrained air along the surface of each air curtain and in particular at regions A, thus causing a reduction of pressure in those regions. Air therefore flows in the direction BC and is carried round, if the system is operating correctly, to form vortices 15 and 16. Under normal conditions of operation the system of flow shown in Fig. 1 is stable so long as the pressure at A is greater than the pressure outside the relevant curtain. If, however, the pressure at A falls sufficiently due to an undesirable alteration in trim or other reason, the curtain jets, instead of being deflected outwards, maintain their inward flow by clinging to the undersurface of the vehicle by a Coarda effect, thus resulting in a loss of cushion pressure. To prevent the reduction in pressure at A a nozzle 22, Fig. 3, is provided directed towards the region at which the loss may occur, through which air is discharged at a pressure higher than the cushion pressure. Nozzles 22 may be single or continuous and an arrangement is described for blowing air into one of a plurality of annular shaped cavities to promote the generation of vortices to maintain the cushion pressure. In a further embodiment (Fig. 4, not shown), air is drawn from the cushion by a compressor and discharged from a nozzle just inboard of the curtain-forming nozzle or air may be caused to flow from the cushion as the result of differential pressures (Fig. 6, not shown). Specifications 854,211, 893,715 and 944,502 are referred to.

Filed: 1940-06-22
Abstract: 542,085. Cellulose-derivative and synthetic resin articles. FEJER, G. June 22, 1940, No. 10770. [Classes 2 (ii) and 2 (iii)] [Also in Groups VIII and X] A light-transmitting screen made from a translucent or transparent plastic comprises at least one element having a plane flat surface and cell- or channel-forming means moulded together or extruded or formed integral by autogenous jointing, preferably under heat and pressure. Autogenous jointing includes the use of an adhesive of the same genus as the plastic. Suitable plastics are cellulose acetate, cellulose butyrate, ethyl cellulose, and polyvinyl or polyacrylic resins. As shown in Figs. 1 and 2 an inner corrugated sheet of cellulose acetate 3 is adhered by the apices of the corrugations to two outer flat sheets 1, 2. The cells may be flattened by pressure traverse to, as at 4, or longitudinally of the corrugations. Such flattened portions may be used to connect units by securing overlapping parts by adhesives or by bending over to form interengaging hooks. Inter-communicating channels may be formed by shaping the inner sheet 10 as shown in Fig. 5. Closed cells may be formed by perforating the inner sheet 12 to form apertures 13 as shown in Fig. 6. Screens may be secured together face to face by adhesive or by tape or strip binding round the edges, or to glass sheets by adhesive or by means of their flattened edge portions. Where two screen units are to be secured to a larger area of glass adjacent flattened portions are received in channel-shaped cellulose acetate strips which may be directly secured to the glass by adhesive or with the aid of an adhesive-coated fabric strip. The screens may be applied to the underside of pavement lights or glass tiles by bedding the flattened margins together with the glass in the channels of the supporting frame. Reference has been directed by the Comptroller to Specification 528,545, [Group VIII].
