Title: Improvements in the manufacture of damp proof matches
IPC: C06F3/00
Filed: 1920-07-02
Abstract: 145,798. Dubrisay, R. July 3, 1919, [Convention date]. Matches.-A process for making damp-proof matches consists in using in the paste from which the heads are formed an agglutinating substance formed by the condensation product of a mixture of substances having the properties of phenol and of an aldehyde. These substances react when heated and produce, in the presence of suitable catalysers, insoluble bodies. For example, a paste is prepared by placing the powdered constituents in a bath containing water, phenol aldehyde, and soda, the stalks are dipped into this bath and after removal the tips are allowed to harden. The aldehyde and the catalyser, which may be hydrochloric acid, may be used in the form of vapour. An example of a suitable paste is the following : 15 parts of resorcin, 15 parts of formalin, 14 parts of soda, 35 parts of potassium chlorate, and 21 parts of powdered glass.

Title: Improvements in aeroplanes
IPC: B64C23/00
Filed: 1929-06-14
Abstract: 328,842. Davis, J. H., and Air Line Transportation Co. June 14, 1929. Aeroplanes; machines supported by direct fluid-pressure apparatus; p r o p e l l i n g; controlling.-An aeroplane is provided with air beaters which are moved with great velocity on one stroke and relatively slowly on the opposite stroke, means being provided for preventing lateral diffusion of the displaced air during the descent of the beater. According to one form an aeroplane having an engine M and wings W is provided with a series of open-ended cylindrical housings 1 pivotally mounted in frames on either side of the fuselage F. An air beater or piston 2 is slidably carried in each housing and is guided by piston rods 2a, 2b passing through the hubs of spiders fitted at top and bottom of the bousing. The beaters 2 are reciprocated by the crank mechanism shewn in Fig. 4 from a shaft 5 connected by a spring coupling, Fig. 5, to an engine shaft 7. Springs 3 surrounding the housings 1 and piston rods 2a are adapted to be compressed on the upward movement of the beaters and to effect their downward movement. The driven shaft 5 is spigoted into the driving shaft 7 and coupled thereto by spring 6, the strength of which is equal to or greater than the combined strengths of the springs 3. This coupling enables the shaft 5 to lag behind shaft 7 during the relatively slow upward movement of the beaters and to move with increased velocity during their downward stroke. In an alternative construction, Fig. 6, the air beaters are arranged in openings in the wings so that when in their lowered position they form a continuation of the lower surface of the wing. Each transverse row of beaters is operated independently so that rows may be operated successively or simultaneously as desired. The beaters on either side of the fuselage may be operated independently also for controlling the aeroplane. Each air beater is operated by a crank arm 2a on a shaft 2 rocked by a crank arm 2b pivotally connected to a rod 3 extending to the fuselage. The beaters are normally held in a lowered position by springs 3s, Fig. 8. A shaft 4b driven by gears 4e from a pinion m on the engine M through a clutch 4g carries driving discs 4 provided with pins 4a which, as the discs rotate', engage heads 3b carried on the rods, 3 and draw them inwardly to raise the beaters. Further rotation of the disc causes release of the head whereupon the beaters are driven downwardly by the associated spring 3s and arrested by a, stop 3c. The clutches 4g are controlled by levers 4h which may also control means for raising the ends of the rods 3 with the heads 3b clear of the discs 4; suitable means are shewn in Fig. 10 in which 3g is a guide plate shewn sectioned in Fig. 8. According to modifications the air beaters may be hinged and vibrated, or be diaphragms.
