Title: Improvements in or relating to mechanical time fuses
IPC: F42C9/04
Filed: 1927-06-02
Abstract: 272,226. Skoda Works, Plzen. June 4, 1926, [Convention date]. Void [Published under Sect. 91 of the Acts]. Projectile fuzes.-A time fuze is separated from the bursting charge of the projectile by a safety disc, which has to be broken or damaged by the power of a spring or centrifugal force, or by the explosion of a small charge, or the air resistance, before the projectile can be exploded. In the base fuze shown in Fig. 3, the spring striker 6 of a clockwork time fuze 1, when released by its trigger device, strikes a percussion cap 8, which fires a small charge 9. The explosion pressure from this charge is led by passages 11 to the safey disc 12, which it deforms, and drives a firing pin 13 against a percussion cap 15, firing the main charge of the projectile. The firing pin 13 is normally locked by a shear wire 25. The clockwork is set b means of a rotatable disc 17 connected to the clockwork by keys 21 having longitudinal but no lateral play. The disc is made gastight by a surrounding ring 18. The small explosive charge 9 and the percussion cap 8 are mounted in a thimble 10, which is carried separately from the fuze and is attached thereto only when the fuze is to be used. In a modification, the firing pin 6 is arranged in the opposite direction and strikes the: cap 15 after piercing the safety disc 12. In another modification, the whole, fuze is reversed in direction and arranged as a nose fuze, and the firing pin 13 is normally locked by centrifugal holts.

Abstract: <PICT:0698947/III/1> The surface treatment of cardboard, paper or the like by applying wax or other fluent material is effected by passing the cardboard vertically through preheating means and thence vertically through a pair of waxing or like rolls.  Carton blanks 22 are drawn singly from a feed tray 21 by feed rolls 20 and 18, to pass between endless bands 19, which project the blanks vertically downwards between one or more pairs of heating rolls 17 and thence between waxing rolls 11 and 12 which rotate in baths of liquid wax 13 and 14, wax being held in their reticulated, grooved or otherwise indented surfaces.  The blanks may then pass down into a bath 23 of water, refrigerated brine or other liquid, to impart a gloss, whence they are withdrawn by an endless belt 24.  Portions of one face of the blank may be left unwaxed e.g. for glue laps, by removing wax from the depressions of one roll by means of a rubber squeegee roll 25 of appropriate pattern.  Wax may be applied to one face only of the blanks by providing one of the waxing rolls with a plain surface associated with a doctor blade, or by running only one roll in a bath.

Filed: 1919-06-17
Abstract: 149,817. Muntz, C. A., and Baker, A. H. S. June 17, 1919. Spray burners.-For heating cooking-ranges &c. an oil-burning apparatus comprises a steamgenerator a consisting of an air cylinder having pins s on its exterior and supplying steam to an injector e, to which oil is admitted by pipes n and k. Steam entering the injector by a pipe f is' given a rotary motion by passing through inclined grooves h in a plug j, mixes with oil from the pipe k in an atomizing chamber p and the mixture is burned at the nozzle q under the boiler a. Water is supplied to the boiler by a pipe g from a water tank, and the height of the tank above the generator governs the steam pressure in the generator, an increase in the steam pressure preventing water from entering the generator.
