Patent GB-1429185-A (GB)
Title: Toilet apparatus
IPC: E03D5/016
Filed: 1972-04-21
Abstract: 1429185 Sanitary closets WESTINGHOUSE BRAKE & SIGNAL CO Ltd 10 April 1973 [21 April 1972] 18644/72 Heading E1C In a recirculating pump-flushed closet, the liquid and waste flushed from the pan is received in a first region of a receiver from which it flows through a filter to a second region, the flow path including a fluid-flow restricting means which sets a slower rate of flow through the filter than the draw-off rate effectable by the flushing pump. In the preferred embodiment shown, which is for fitting to a railway carriage, the interior of a casing 1 is divided by a partition 131 into two chambers in one of which is fitted a receptacle incorporating a filter 111 and forming the first region 3 into which waste and flushing liquid from the pan is received. The other chamber forms the second region 12 which communicates with a third region surrounding the filter 111 by a restricted aperture 13 in the partition 131, the aperture 13 causing the liquid to pass through the filter at a slower rate than that at which the recirculation pump 14, Fig. 4, sucks it out of region 12 to flush the pan. As a result, the power to the pump motor can be controlled by a level-sensing switch 171 such that the pump remains operative only until the liquid level in region 12 has dropped below the switch 171. In the preferred embodiment, however, the electric circuit (Fig. 5, not shown) is more complex since the toilet includes a macerator 7 which automatically macerates the contents of the region 3 and empties the interior of the casing into a discharge arrangement 8, 9, 10 when the liquid level in region 12 rises sufficiently to operate a switch 161, or the level in this region rises sufficiently to operate a further, optional, switch (181, Fig. 5a, not shown), after which region 12 and the third region are automatically refilled with fresh flushing fluid to the level of switch 171 by opening a solenoid valve 194 communicating the contents of a flushing liquid storage tank 192 with a pipe 21 having a brand 211. At the same time, a dosing pump 193 is energised to supply a quantity of disinfectant from a tank 191 in the casing 1 to the region 3. The circuit includes a timer, a foot-operated switch 20 to initiate a flush, and a dooroperated switch operated by the closet door whereby the emptying and refilling of the toilet occurs only when the closet has been vacated.

Abstract: 957,880. Making flexible tubes. TUYAUX FLEXIBLES RUDOLPH. May 16, 1962, No. 18925/62. Heading F2P. Apparatus for continuously forming a tube having a longitudinal seam from a band of indefinite length and consisting of reinforcing material and of natural or synthetic latex, comprises means to continuously pull the band through a trough supplied with liquid latex, a calibrating throat the outlet of the trough, means for causing the band to move in a direction parallel to the bottom of the trough at a predetermined distance from the bottom, and a base plate parallel to and in continuation of the bottom of the trough, the length of the base plate being large enough to let the latex, in which the reinforcing band is embedded, set during the travel of the band above the base plate. There are known means for continuously guiding and progressively deforming the pulled band to form a continuous tube, and known means to unite the overlapping margins of the band. As shown, a trough 4 on a glass table is supplied with latex from a tank 5 and has an outlet 6 the throat of which is increased in effectiveness by a scraper 7 which determines the thickness of latex applied to at least one band 8 drawn from a roll 9; a centring roller 13 determines the height of the band above the table. The coated textile or metal band is subjected to the heat of adjustable, infra-red radiators 15 and setting of the latex is accompanied by a discharge of water which is collected in a drain 17. The band passes to a calendering device 18 and then to a conical tube-forming guide 19. The overlapped margins of the band are subjected to the action of pressure rollers 21, 22, and the tube is received on a conveyer 23 and passed to a drying and vulcanizing store.

Patent GB-757333-A (GB)
Title: Improvements in and relating to the production of hydrogen and carbon monoxide synthesis gas
IPC: C01B3/38
Filed: 1953-07-10
Abstract: In the production of synthesis gas comprising essentially hydrogen and carbon monoxide from fuel oils containing hydrocarbons by reaction with steam and oxygen, the oil is introduced into the reaction chamber by atomization with steam, and a catalyst is mixed with the oil prior to or during its introduction.  The oxygen may be introduced separately, e.g. as air mixed with additional steam, and may be given a whirling motion to assist mixing.  The amount of oxygen used may be regulated to control the reaction temperature, e.g. at 1100 DEG -1200 DEG C.  The steam and oxygen are preheated, e.g. to 600-700 DEG C.  The oil is heated to 100 DEG -150 DEG C. to increase fluidity and is injected together with superheated steam at a pressure of several atmospheres through nozzles having diverging jets. Suitable catalysts are salts of alkaline earth metals, e.g. calcium or magnesium nitrate in an amount of at least 1 gram per litre of oil.  The catalyst is suspended in the oil or added as an aqueous solution.  An example describes the reaction of heavy fuel oil with oxygen and steam.  If air is used instead of oxygen, a nitrogen-containing gas suitable for the synthesis of ammonia is obtained.  Reference is also made to the use of the gas for the synthesis of methanol.
