Title: Improvements in plants for fire extinguishing purposes
IPC: A62C5/00
Filed: 1923-11-21
Abstract: 226,351. Fyrene Co., Ltd., and Bedford, H. E. Nov. 21, 1923. Fire-extinguishing by foam; fire-engines.-In foam fire-extinguishing plant the acid is kept in concentrated form and diluted with water before being mixed with the alkali and foam producer at the point of use. The acid solution may be drawn out of a tank at a lower level than the alkali tank by an injector supplied with water from an elevated tank or pump. The water passing through a nozzle 3 draws the acid up a pipe n and through a check valve 2. An atmospheric valve 4 stops the syphon action when the apparatus is turned off. The pressure heads of the solutions are equalized by suitably proportioning the injector nozzle or by a reducing valve. If the alkali tank is arranged at a low level the alkali solutions may be forced out by gas pressure or a pump, or use may be made of a steam injector, the steam pipe of which may be provided with a branch to supply an injector for the acid tank to bring the acid solution pressure head up to that of the alkali. The acid and alkali may be drawn out by coupled pumps and if they draw out of the top of the tanks a priming cock is provided for the pumps. The cocks controlling the acid and alkali pipes may be interconnected for simultaneous operation. The pipes and injectors may be multiplied to supply more than one pair of pipes, or the pipes may be branched. To clear away sediment &c., the alkali solution may be circulated through an external pipe by a pump. In a modification, a fire-engine is adapted to project water or foam by two coupled pumps each connected to the hollow body of a cock, one of which allows acid from either of two tanks to mix with water and the other supplies alkali from either of two other tanks ; or water alone may pass through the two cocks.

Title: Improved apparatus for controlling or modulating radiation, more particularly for the purposes of recording sound and for picture-telegraphy
IPC: H04N5/74
Filed: 1931-10-24
Abstract: 394,672. Copying-telegraphy. MœLLER, C., 86, Soorstrasse, Charlottenburg, Berlin. Oct. 24, 1931, No. 29557. [Class 40 (iii).] An arrangement for controlling radiation for use in picture telegraphy or the like in which the position of a beam with respect to a screen 15 is modified by alterations imparted to a control surface 11, consists in employing optical means to constrict the beam at the controlling surface in that dimension, relatively to the other dimensions of the beam at the controlling surface, in which the ratio between the total section of the beam lying in the plane of the .screen and the fraction of this section passing through or interrupted by the screen is little varied by alterations in the inclination of the rays due to the controlling surface. The screen 15 is provided with a slot arranged as shown in Fig. 2, and the constriction is effected in the longitudinal direction of the slit. since in this. direction a smaller proportion of the rays is stopped by the screen 15 when the surface is moved by a controlling electrode or other means from the flat position to a curved position. The constriction may be effected by a cylindrical lens or mirror which is placed between an illuminated slit in a screen 8 and the controlling surface 11 with its axis at right-angles to the length of the slit in the screen 15. The lens is spaced from the surface 11 a distance equal to its focal length. The constriction may, alternatively, be effected by an optical system comprising a spherical lens 9 and a cylindrical lens 10, which. may be formed as a unit, and a similar system may be placed between the surface 11 and screen 15. The cylindrical lens may be replaced by a concave spherical mirror, the position of the surface 11 being correspondingly adjusted. A modification shown in Fig. 4 comprises an incandescent lamp with a vertical filament 70, lens 71, transverse slit 72, and objective 73. The lenses 71, 73 form a sharp line image of the filament on the membrane 74. The lens 71 and slit 72 may be formed as a single unit with the slit 72 provided on a mirrored surface on the lens. The control membrane is adapted to be curved by a pressure applied to one side, or by electrostatic or magnetic attraction. Electrodes or electromagnets may be disposed symmetrically or non-symmetrically of the membrane on one or both sides. Where an electrode is disposed on each side of the membrane, one may be formed of transparent medium to transmit the radiation. Alternatively, such electrode may be solid and provided with a slit coincident with the incident beam, or of grating or net form and provided with a section of greater mesh than the remainder to permit the passage of the incident beam. The control of the radiation at the membrane may be also effected by refraction or diffraction. If desired, the screen may be transparent and provided with an opaque section of the same dimensions as the slit provided in the opaque section.

Title: Method of treating nylon filament yarn for use in composite rubber structures
Inventor: MULLER FERDINAND HARRY
IPC: C08J5/06
Filed: 1952-11-24
Abstract: Multi-filament nylon yarn is treated with an aqueous dispersion containing a low concentration of an amide of a fatty oil acid, and thereafter with a resorcin-formaldehyde-rubber latex mix.  The aqueous dispersion preferably contains about 2 per cent of the fatty oil acid amide, which may be prepared from coconut, soya, linseed, cotton-seed or rape-seed fatty acids.  In an example, a multifilament nylon yarn is passed through an aqueous bath containing a fatty oil acid amide, through squeeze rolls and then through a dip tank containing rubber latex, water, resorcin, formaldehyde, and caustic soda, and after squeezing is dried under tension.  The treatment makes the yarn suitable for adhesion to rubber.ALSO:Multi-filament nylon is pretreated to give a yarn suitable for use in composite rubber structures such as tyres by applying to the yarn an aqueous dispersion containing a low concentration of an amide of a fatty oil acid, and thereafter applying to the yarn a resorcinformaldehyde-rubber latex mix.

Abstract: 782,234. Coiling. BLASHILL, A. E. Oct. 20, 1955 [Nov. 3, 1954], No. 29974/55. Class 83 (4). [Also in Group XXIV] A machine for manufacturing wire fabric of the chain-link type has a main drive shaft 12, a weaving spindle 14 which carries the flat former bar on which the wire is wound, an overrunning clutch 36 having a driven and a driving element, a low-speed transmission 24, 38 connecting the shaft 12 to the driving element of the clutch, a high-speed transmission 22, 34 connecting the shaft 12 to the driven element of the clutch, the high-speed transmission and the lowspeed transmission being connected to the spindle 14 through a roller-cam clutch 32. In operation, the weaving spindle 14 is rotated one turn at slow speed from the shaft 12 through gear 24 fast thereon, gear 38 rotatably mounted on spindle 14, overrun clutch 36, gear 34, in one with the inner member of the clutch 36, and the roller-cam clutch 32, the inner plate of which is keyed on the spindle 14. A onerevolution shaft 16, driven from the shaft 12 through gears 26, 144, 54 and clutch 52, rotates through bevel gears a cam-shaft 90 having a finger 92 thereon which rocks an arm 104 fast on a spindle 82. This causes yoke arms 88 on the shaft 82 to engage a clutch 20, 201 to transmit power from the shaft 12 through the high speed transmission 22, 34, overrunning the clutch 36, through the clutch 32 to the spindle 14. The clutch 52 of the onerevolution shaft 16 is disengaged by an arm 120 engaging a finger 56 on the clutch, during the high-speed rotation of the spindle 14. The spindle 14 rotates at high speed until a lug 78 on a chain 70, driven from a worm 40 on the spindle 14, rocks an arm 80 on the shaft 82 to disengage the clutch 20 whereupon the spindle recommences slow speed rotation for one turn. The spindle 14 is halted at the end of this low speed rotation by the rocking of an arm 122 of a three-armed lever 116, 120, 122 into the path of a dog 42<SP>1</SP> on the clutch 32 to disengage the clutch. The rocking is effected by the engagement of a lug 76 on the chain 70, with a collar 114 on a rod 112 connected to the threearmed lever. The said rocking of the threearmed lever allows the clutch 52 to re-engage. Consequent rotation of the shaft 16 causes a projection 48 thereon to move a bar 124 to move the rod 112 and collar 114 from the lug 76 and allow spring means to disengage the arm 122 from the dog 421 of the clutch 32. A new cycle of operation is thus commenced with a low-speed rotation of the spindle 14. Specification 510,948 is referred to.
