Title: Process of colouring wood veneers and the like
IPC: B27K5/02
Filed: 1934-06-25
Abstract: 427,069. Colouring wood. SINGER MANUFACTURING CO., Elizabeth, New Jersey, U.S.A. June 25, 1934, No. 18671. Convention date, June 24, 1933. [Class 140] In a process of colouring wood veneers by treatment with ammonia at an elevated temperature in a closed vessel, the temperature in the vessel is first raised to a point ensuring complete vaporization of the water-content of the veneers, which are then subjected to the action of ammonia at substantially atmospheric pressure, i.e. between 1À07 and 1À33 atmospheres, while maintaining the temperature constant. The wood may be dried, preferably to a moisture content of 4 per cent, and loaded into a receptacle provided with a blow-off valve. The temperature is then raised by steam pipes within the vessel to 250‹ F. Superheated ammonia gas at approximately the same temperature is then introduced at a slightly increased pressure either by heating aqueous ammonia to 255‹ F. in an external evaporator or by injecting aqueous ammonia into an evaporating pan within the vessel. The temperature and pressure are maintained constant for about 12 hours, any reduction of pressure due to ammonia absorption being compensated by the introduction of further ammonia.

Title: Improved method for the production of articles of wearing apparel
IPC: A41B3/10
Filed: 1936-07-06
Abstract: 477,419. Wearing-apparel. LIEBOWITZ, B. July 6,1936, No. 18706. Convention date, July 5, 1935. [Class 141] A method for producing a fold line in articles of wearing-apparel, e.g. collars and cuffs, made up from a plurality of plies united by an inner adhesive stiffening lining is characterized in that a narrow zone of reduced stiffness is created at the fold line by mechanically preventing or breaking down the adhesion between one or more of the outer plies of the article and the inner stiffening lining. In Figs. 1 and 2, the adhesion at the fold line of a collar is prevented by interposing a cord 5a between the lining 2 and the bottom ply 3 of the collar top 8. The cord 5a does not extend to the edges of the collar top so that in wear a roll effect is produced at the ends of the collar. In a modification, the adhesion at the fold line is prevented by interposing a thin layer of paper, wax, or other suitable material, between the lining and the top or bottom ply of the collar. In another modification, Fig. 4, adhesion at the fold line is prevented by cutting away the bottom ply 3 of the collar at 5f. In a further modification, Figs. 17 and 18, the adhesion between the ply 19 and the lining 20 of the collar top 11 is broken down by inserting a probe 18 therebetween after the plies have been united together. The probe 18 is guided as it is pushed into the collar top by means of grooves 16 and 17 provided in upper and lower blocks 14, 15 between which the collar top is supported.

A device for dropping loads from aircraft comprises a cup-shaped member 3 mounted in a cylindrical portion 2 of a fixed part 1 of the aircraft and having a stem secured by a nut 5. Locking balls 7 engaging a shoulder 4 within the member 3 are housed in radial openings in a cylindrical body 6 and prevented from escaping by the enlarged head 10 of a piston 9 which is in turn locked in position by a coil spring 11 bearing against a push rod 13. A lateral enlargement of the cylinder 6 houses an electrically ignited cartridge 15 connected through a conductor 18 to a current source 20. On ignition, gases from the cartridge expand into a chamber 21 and force the piston 9 against the base of the cup 3 so that the balls 7 are freed and the cylinder 6 is ejected. The second terminal of the cartridge may be earthed or connected by a return wire to the source 20. The piston 9 may also be released by pushing a hand control member 22 against the action of a spring 23. In a modification the cylinder together with the piston form part of the aircraft structure and the balls engage a shoulder within a releasable cup-shaped member. Fig. 3 shows an arrangement wherein the releasable cylinder 29 is locked by balls pressing against an internal shoulder of a tubular socket 30, escape of the balls being prevented by the piston 10. To fit the socket member 30 securely in the aircraft wing 31, it is given a tapered outer surface 37. The locking balls may be replaced by non- spherical members or by pawls.
