Title: Improvements in or relating to Fire Extinguishers
Inventor: HARWOOD PETER WILLIAM
IPC: A62C13/00
Filed: 1969-04-14
Abstract: 1,199,139. Dry powder fire extinguishers. FIREWARD Ltd. 14 April, 1969, No. 19031/ 69. Heading A5A. A fire extinguisher of the dry powder/compressed gas type which may be operated intermittently comprises casing 1 in which is mounted cage 6 enclosing compressed gas bulb 15 inverted over firing pin 14, spring-loaded plunger 25 movable to urge the bulb against the pin, gas tube 16 leading from aperture 13 in the bottom of cage 6 to the bottom of the casing, and outlet tube 4 surrounding the cage and the gas tube up which compressed gas and powder in admixture can pass in passage, via apertures 11 (Fig. 2) in the cage, to plunger 25, which also acts as an outlet valve for the mixture. In operation, hand lever 32 pivotally attached to cap 3 depresses plunger 25 against the action of spring 24, forcing the gas bulb against the firing pin. Released gas, e.g. CO 2 , passes down tube 16 and forces powder extinguishant, e.g. NaHCO 3 . up tube 4, through apertures 11 and thence via bore 28 adjacent stem 29 of the plunger to outlet nozzle 35. Release of the plunger closes the lower end of outlet bore 28 so that the gas/powder jet can be intermittently controlled by simple operation of lever 32. Accidental operation is prevented by locking pin 34 in upper part 27 of the plunger. Cap 3 is also provided with integral grip 37, and safety valve 38 consisting of brass tube 39, compression spring 40 and ball 41. Bracket 42 provides a mounting means for the extinguisher.

Abstract: 959,559. Removing metal by fusion. RANK XEROX Ltd. May 30, 1960 [June 1, 1959], No. 19039/60. Heading B3V. [Also in Divisions B6, G1 and H4] A direct recording electrostatic printer comprises a web 10 having a conductive coating 11 on which images are directly produced by the selective removal of the coating by the discharge of a print face which may be of character shape. The insulating layer 15 of the web may be a plastic film such as polyethylene cellulose acetate, ethyl cellulose, polyethylene terephthalate, or regular dried or coated papers, glass or ceramics, while the coating may be metal such as aluminium. In the embodiment shown rings of characters 53 on a drum 52 are constantly rotated past fixed electrodes 55 which are pulsed sequentially at the correct time to imprint the character then opposite the electrode 55 by removal of the film 11 effected by the electrostatic discharge. In a modification, a row of electrodes are pulsed to produce a whole line of characters during a single drum rotation. In the embodiment of Fig. 5, point-shaped electrodes 78 may be used to record analogue information on a record web 10 passing below. The distance of the points from a datum line representing an instantaneous valve. A curve constituted by a train of dots is thus traced out. It is also stated that characters may be printed using a seven by five matrix of point print faces suitably pulsed or the character print faces may be a combined 0 and 1 pulsed alternatively to record data according to a binary code. Specification 926,361 is referred to.
