Title: Process for the improvement of textile materials
IPC: D06M13/12
Filed: 1935-01-21
Abstract: The resistance to creasing of textile materials is improved by causing an aldehyde to react within the material in the presence of an oil or of a plasticizer for cellulose derivatives, in the absence of substances not derived from the base of the materials which are capable of condensation with the aldehyde under the conditions of the treatment.  Particularly useful oils or plasticizers are the higher fatty acids or alcohols, or esters thereof, glycerine esters such as olive oil, castor oil, and cetyl or ceryl palmitates, alkylolamine salts of oleic or similar fatty acid, and sulphonated or sulphated acids, alcohols, or esters, such as turkey red oil.  Materials comprising cellulose derivatives or partially saponified cellulose esters may be treated while swollen with suitable agents.  In examples: (1) viscose or saponified cellulose acetate artificial silk is treated successively with formaldehyde containing hydrochloric acid and ethyl stearate, dried and heated; (2) viscose fabric is soaked in a solution containing formaldehyde, hydrochloric acid, and triethanolamine oleate, dried and heated; (3) the solution of (2) is replaced by formaldehyde and turkey red oil; (4) fabric is soaked in a solution containing the substance sold under the Registered Trade Mark "Brilliant Avirol" and formaldehyde, with or without hydrochloric acid, dried and heated; (5) the solution of (4) is substituted by a suspension of oleyl alcohol in formaldehyde; (6) partially saponified cellulose acetate is swollen in aqueous acetone and treated as in any previous example.

Abstract: 961,543. Wood panels. PHOENIX TIMBER CO. Ltd. July 11, 1960 [July 13, 1959], No. 24056/59. Heading B5L. Wood parquet for floors or walls is made by adhering together pieces 12 or 24 of wood in a desired pattern with the grain running in the direction (shown by arrows 14 or 22) of the greatest dimension of the pieces in an end face of the block so formed and cutting or slicing from the end face panels 10 or 20. The block 13 of Fig. 1 is made by adhering together five pieces 12, cross-cutting them to the shape of rectangular prisms, machining true at least two inner faces and adhering four such prisms together. In Fig. 3, the pieces 24 of triangular cross-section are cut from a board, adhered together to form a rectangular prism and sixteen of these prisms are adhered together to form the block 25. In both forms, the pieces are lengthened by joining them end to end, the joint being effected between faces that lie at an angle to the end face of the block so that the joint line will be inconspicuous on the face of a panel. The panels may be bevelled at their upper edges to make less obvious small differences in the heights of adjacent panels. The adhesive used in making the block is preferably weaker than that used for adhering the panels to a floor or other surface so that individual pieces may shrink apart before becoming detached from the surface; alternatively, the adhesive may be elastic and have a frothing agent added so that an expanded compressible joint is obtained. The inner angle of the triangular pieces may be slightly greater than 90 degrees to allow space for expansion at the centre of each square.

Filaments; lamps with filaments non-conductive when cold.-Crystalline substances other than metals, for example oxides, are treated to adapt them for use as filaments by subjecting them to mechanical working while they are protected against crumbling to pieces, whereby their tenacity and plasticity are improved, and they are also treated to increase the size of the crystals. The substance mav be enclosed in a copper, nickel, iron, or other ductile metal tube, which is drawn or rolled down to the required dimensions at a high temperature, and the tube is finally removed by dissolving or evaporating it, or otherwise. Refractory oxides, such as thoria, may be enclosed in a tungsten tube. Alternatively, the separate particles of the substance may be coated with a ductile metal, or the substance may be deposited by electrolysis upon the metal. Coated particles are consolidated by pressure before being worked mechanically. The substance may be mixed with a metal so as to form a composition that is plastic at the working temperature, for example thoria may be mixed with copper. After the removal of the metal when the mechanical working is completed, the substance in the form of rods or wires is heated to effect growth of the crystals, by passing it through a zone of steep temperature gradient or otherwise. The heat treatment may be effected before removing the ductile envelope, and in some cases before the mechanical working.

Filed: 1959-07-15
Abstract: 878,385. Equalizing load on wheels; hydraulic shock absorbers. RECHERCHES ETUDES PRODUCTION S.A.R.L. July 15, 1959 [Sept. 3, 1958; Sept. 10, 1958], No. 24389/59. Classes 108(2) and 108(3). [Also in Group XXXIII] An aircraft tandem landing gear comprises two cranked parallel levers 1 and 8, Fig. 4, pivotally mounted on parallel axles A1, A2, an arm of each lever carrying a wheel, and the other arm of each lever being coupled to a movable member of a shock absorber, the body 9 of which, with the axles A1 and A2, is fixed to the aircraft, the two movable members and the body of the shock absorber forming one or more communicating cavities, the volume of which decreases when the wheels touch down together or separately, and which are filled with oil and communicate through a narrow orifice with one of two chambers into which a cylinder is divided by a free piston, the one chamber being filled with oil and the other with compressed air. In Fig. 4, the wheel carrying arm of lever 8 contains a normally vertical castoring axis X-X, two elastic members 43 (one shown) one each side of the axis X-X centring the wheel when not on the ground. Fig. 2 shows a section of the shock absorber. The body 9 contains a piston 11 with a hollow rod 12 coupled by a connecting rod 10 to lever 1. A cylinder 13 formed on piston 11 contains a piston 16 with a hollow piston rod 15 coupled by connecting rod 17 to lever 8. The interior of the hollow rod 15 is divided into two chambers 19 and Q by a piston 18. Chamber 14 formed between rod 12 and body 9 communicates with chamber C formed in piston 13, through a valve D. Chamber C communicates with the annular space H between rod 15 and cylinder 13 through an orifice J, and with chamber 19 through a valve G. These chambers are filled with oil, and chamber Q with compressed air. Shoulders 21 on cylinder 13 and 22 on rod 15 abut on to a slidable sleeve K when the wheels are fully extended. When the wheel on lever 1 comes under load, or increased load, piston 11 moves outwardly. Chamber 14 decreases and chamber C increases in volume, there being a nett decrease. Oil thus flows through valves D providing damping, into chamber 19, compressing the air in chamber Q to provide return spring action. When the wheel on lever 8 comes under load, or increased load, piston 16 moves inwardly, and oil flows from chamber C through valve G into chamber 19. The chambers are dimensioned so that the stiffness of the spring action is the same for each wheel. When the wheels do not move equally e.g. when the aircraft pitches on the ground, damping is provided by flow of fluid into and out of chamber H through orifice J. The shock absorber may also be used as a jack, to extend or retract the undercarriage or alter the height of the aircraft when on the ground, by connecting ports P and R, which are isolated during shock absorber action, to a source of fluid under pressure and a reservoir. Specification 872,265 is referred to.
