Title: Improvements in or relating to projectile fuses
IPC: F42C15/24
Filed: 1925-05-11
Abstract: 234,084. Bethlehem Steel Co., (Assignees of Essen, P. D. van). May 15, 1924, [Convention date]. Projrctile fuzes.- A direct-action percussion fuze, Fig. 1, has a cage-like distance-piece 30 between the detonator carrier 20 and the striker 17, which is made hollow for lightness. The front end of this cage has curved spring tongues 31, Fig. 2, which are normally maintained in a groove 19 in the striker by the surrounding wall 29 of the fuze body; and the rear end of the cage has an inturned shoulder 34 and bent lugs 33, which fit over a stirrup 35 and press same against the front end of the detonator carrier. An inertia ring 37 is supported in the forward position shown by a spring 38 and by the lugs 33. In the safe position shown, the secondary detonator 28, which transmits detonation from the primary detonator 25 to the magazine 40, is screened from the latter by a lining 41 of paraffin wax, cerasin wax, or bitumen, which damps down any premature accidental detonation. The charge in the magazine may be compressed pellets of trinitrotoluene, trinitrophenylnitramine, or tetranitraniline. The fuze functions as follows : On discharge, the ring 37 sets back by inertia, and becomes wedged on a tapered part 26 of the detonator carrier. When acceleration is over and air resistance on striker 17 has sufficiently diminished, the spring 38 returns the ring 37 forwards, and with it the detonator carrier and the striker. The striker then projects beyond the fuze body in readiness for impact; the spring tongues 31 lies in an enlarged space 16 and can therefore be forced open by the striker on impact; and the secondary detonator 25 is withdrawn from the liner 41 and can therefore transmit unimpeded detonation to the magazine 40.

Title: Process for the economical utilisation of the exhaust gases from calcination of bicarbonates particularly sodium bicarbonate
Filed: 1955-04-25
Abstract: In the calcination of bicarbonates additional gases are passed through the material under calcination or mixed with the produced exhaust gases so that in combination with the exhaust gases they can be used for the production of synthesis gases in a generator such as a water gas, mixed gas or other generator where steam or carbon dioxide is used for gasifying purposes, or in a system for converting hydrocarbons into carbon monoxide and hydrogen with steam and carbon dioxide.  In the calcination of sodium bicarbonate oxygen, air, or air enriched with oxygen is passed through the sodium bicarbonate so that theexhaust gases comprising water vapour and carbon dioxide may produce synthesis gases in the water gas generator.  In a modification nitrogen or carbon dioxide are used as additional gases and oxygen is added at the gasification stage.  In a further form, hydrocarbons are used as the additional gases and this accelerates the calcination.  The additional gases may be heated.

Title: Method and apparatus for heat setting of cloth layers
IPC: D06C5/00
Filed: 1962-03-29
Abstract: 978,704. Finishing fabrics. K. BRUCHNER, [trading as TROCKENTECHNIK KURT BRUCHNER KOMM-GES.]. March 29, 1962 [April 1, 1961; April 14, 1961], No. 12168/62. Heading D1S. In hot-setting woven or knitted webs of fabric partly or entirely of synthetic fibres, setting is done by means of radiators emitting radiant energy which is absorbed by the fibres whilst maintaining a uniform distance between the radiators and substantially the entire width of the web. The apparatus shown in Fig. 1 has lateral chain rails 1, guiding tension chains 2 which are used for conveying cloth layer 4 by means of pins 3. Infra-red radiators 5 are provided above and possibly below the cloth layer 4 and are curved to allow for the sag of the cloth. The rails 1 are adjustable relative to each other so that the cloth sag can be adjusted to suit the curvature of the radiators. In other similar embodiments air jets support net or plate through which the rays may penetrate are used to support the cloth layer in a horizontal position and the radiators are then made flat. In Fig. 5, after passing through drying apparatus 9 having hot air nozzles 10, the cloth 4 is passed vertically between radiators 5 so that no special means are necessary to position the cloth 4. After passing through the radiators the cloth may be passed through a cooling zone consisting of cold-air nozzles 11. In this embodiment the chains 2 together with the cloth 4 are turned or reversed by means of telescopic roll 12, 13 (Fig. 8), having sprockets 8 at each end. In Fig. 7 the cloth layer 4 is run at an oblique angle through the drying zone 9 and also between radiators 5. Air nozzles 7 are again provided to prevent sagging. The radiators 5 are preferably of rod-shape or of a sheet-like form preferably composed of a larger number of shorter rod-shaped radiators in staggered formation. This enables outer elements to be switched off depending on the width of the cloth and also enables the amount of radiant energy to be varied in accordance with the type of cloth. In a further embodiment (not shown) the radiators are mounted within a box-like structure into which air is blown for cooling the outer surface of the cloth.

Title: Improvements in or relating to vent valves
Inventor: SHAW HORACE LEONARD
IPC: F16K24/04
Filed: 1960-04-06
Abstract: 906,829. Valves. ROLLS-ROYCE Ltd. April 6, 1961 [April 6, 1960], No. 12277/60. Class 135. A vent valve 21 comprises a valve body 22, upstream and downstream valve seats 27, 28, a valve member 24 arranged for movement between the seats, a spring 30 for urging the valve member into contact with the upstream seat, the arrangement being such that when the pressure of a gaseous fluid supplied to the upstream end of the valve body has reached a predetermined value, the valve member will be forced by the pressure against the spring into a position in which it is spaced from both the valve seats and permits gaseous fluid flow through the valve body, the spring, however, permitting seating of the valve member on the downstream valve seat only when the liquid fluid is supplied to the upstream of the valve body so as to act on the valve member. The valve 24 is provided with a closure flange 25 and ports 31, 32 are provided on opposite sides thereof. A spring-loaded relief valve 37 is located within the valve 24 and co-operates with a seat 41. As shown, the valve assembly is mounted on a container 10 into which liquid oxygen is fed through a pipe 11. Upon entry of the liquid oxygen, the latter boils and the gas given off forces the closure flange off the seat 27 into a position between the two seats and thereby permits a rapid escape of gas. When the liquid oxygen rises sufficiently it enters the valve and forces the closure flange on to the seat 28 thereby preventing any further loss of a large volume of gas.
