Inventor: JEWKES WALLACE GRAYHAM
IPC: F23H11/10
Filed: 1962-05-23
Abstract: 975,848. Travelling grate furnaces. JOHN THOMPSON (TRIUMPH STOKER) Ltd. May 14, 1963 [May 23, 1962], No. 19820/62. Heading F4B. In a down-draught system for heating incoming fuel on a travelling, grate stoker, a bottomless chamber 1 and a rear parallel chamber 16 are located transversely between the upper and lower travel paths of the grate 6. Hot'gases are drawn through the fuel bed 17 via an opening 9, past a baffle 11 and through an opening 10 into the chamber 1 connected at one or both ends by a duct 19 containing a damper 22 to the suction inlet of a fan 20 which delivers air under pressure through a duct 21 to one or both ends of the chamber 16 and thence out through its open rear and up through the fuel bed. The gaps between the front and rear walls of the chamber 1 and the lower travel of the grate 6 are sealed by flexible material or hinged flaps trailing on the grate 6 such as to allow the grate to clear the chamber 1 of deposits automatically without impeding its motion.

Title: Compositions for use in suppositories
IPC: A61K9/02
Filed: 1958-06-20
Abstract: A suppository base comprises a water insoluble base e.g. one or more fatty acid glycerides and a pharmaceutically acceptable gel forming soap in a quantity such that the viscosity of the composition at its casting temperature is about 100 centipoises, the composition being solid as temperatures below 25 DEG C. and softenable at normal human body temperatures.  The preferred glycerides are those of saturated C12-C18 fatty acids. The preferred soaps are aluminium soaps of long chain fatty acids especially aluminium mono- and di-stearate.  They are used in quantities of 0,5 to 3,0, and preferably 2% based on the glyceride.  The soap is dissolved in an organic solvent such as chloroform, petroleum ether or benzene, added to the melted glycaride, the solvent removed and one or more solid medicaments e.g. bismuth subnitrate or subgallate incorporated therein, cast into suppository moulds and allowed to set.  Specification 694,970 is referred to.

Patent GB-1330944-A (GB)
Title: Process and apparatus for the continuous treatment of threads
IPC: D06B15/09
Filed: 1971-04-19
Abstract: 1330944 Treatment of thread OMNIUM DE PROSPECTIVE INDUSTRIELLE 19 April 1971 [21 Jan 1970] 20009/71 Heading D1F [Also in Division F4] A process of removing treatment fluid from a thread comprises passing the thread through a convergent-divergent nozzle, simultaneously passing a gas inert to the thread through the nozzle to produce a supersonic flow of gas in the region of that end of the nozzle which is downstream with respect to the direction of flow of the gas, a zone of low gas pressure being thereby created in the supersonic flow, and passing the thread through the zone. The thread may be passed through two such nozzles, the second (in the direction of displacement of the thread) of said nozzles being permanently fed with air at a pressure higher than the critical pressure at the constriction of the nozzle, whilst the first nozzle is fed with air at a pressure which is alternately lower then higher than the critical pressure at the constriction of the first nozzle. By this means successive treated and non-treated zones appear. The above process may be carried out in the apparatus shown in Fig. 1. In this apparatus thread A passes through treatment chambers 1-6. In chamber 1; an acid treatment (the acid being supplied from tank 10) is carried out, the thread passing through apertures 1b and 1c. Recovery chambers 7 and 8 ensure the recovery of any leakage liquid to tank 10. The chambers 2, 4 and 6 correspond to drying zones. Chambers 8, 14, 15, 16, 17 and 22 act as recovery chambers returning treatment liquids to tanks 18, 19, neutralising tank 12 and washing tank 20. The inlet and outlet apertures of the chambers 2, 4 and 6 are each in the shape of convergent-divergent nozzles, e.g. for chamber 2 referenced 2b and 2c. After the various drying steps the thread may be finally treated in a heater 24. Means are provided to control the pressure valves in the nozzles and chambers. These means may be in the form of a binary trigger circuit, a sonic or supersonic generator or a vibrating reed whistle (Figs. 4-6, not shown).

Title: Reverse Osmosis Membrane and method for its manufacture
IPC: B32B23/20
Filed: 1967-05-02
Abstract: 1,159,218. Cellulose acetate membrane. AEROJET-GENERAL CORP. 2 May, 1967 [2 May, 1966], No. 20291/67. Headnig B5B. [Also in Division C3] Cellulose acetate membranes used as desalination membranes have an acetyl content of 41À5% to 42À7% based on the weight of the cellulose. The critical acetyl range of the cellulose acetate used may be obtained by blending commercially available cellulose acetate compositions to attain the desired acetyl content, or the cellulose acetate solution may be initially prepared to have such an acetyl content. The membranes are formed by casting a solution containing the film forming cellulose ester above, a swelling agent, and an organic polar solvent, on to a casting surface by methods well known in the art.
Patent GB-1583074-A (GB)
Title: Purification of waste water
IPC: B01D37/03
Filed: 1977-05-13
Abstract: A process for the treatment of effluent which contains solid, sedimentable, colloidal and truly dissolved substances and whose impurities are at least partially of an organic nature, with a reduction in the chemical and biochemical oxygen demand, is characterised in that flocculation aids are added to the effluent and the solids-containing effluent is passed by gravity through a supporting fabric located in a suspending device. During the filtration step, a combination filter composed of a) this supporting fabric and b) a primary filter layer of the solids separated off is formed, by means of which the further effluent introduced is freed of the major part of the solid particles. The filtration through this combination filter has the effect that not only the sedimentable and also a substantial part of the colloidally dissolved substances, but also a major part of the truly dissolved substances are separated off, so that a filtrate is obtained, for the treatment of which a biological oxygen demand is required which is reduced by up to 90 %, relative to a municipal effluent freed of solids. The process can be combined with equipment for biological and/or chemical-physical treatment. Equipment in which the process according to the invention is carried out is described.
