Abstract: 1517819 Producing white or grey cements SOC DES CIMENTS FRANCAIS 17 Nov 1976 [17 Nov 1975] 47869/76 Addition to 1,090,539 Heading C1H [Also in Division F4] Clinkers of white or grey cements are produced by preheating unfired clays so as to decarbonate them at approximately 850‹C, introducing the decarbonated clays into a roasting kiln at 1450‹C and then cooling in two distinct phases, namely a first phase in which the roasted material is cooled to approximately 700‹C by means of a flow of air to act as combustion-supporting air for the roasting kiln burner and a second phase in which the roasted material is cooled from 700‹C to ambient temperature during which the clinker coloured during the first phase is either cooled in order to produce grey cement clinker, or reheated to 800‹ to 1200‹C and then cooled in the absence of air, i.e. either in water or water vapour or in a neutral or reducing atmosphere in order to produce white cement clinker. An installation for carrying out the above process comprises a preheating and decarbonation unit 1 connected to a roasting kiln 3 which is in turn, connected to a first cooler 4, a second cooler 7, a heating kiln 8 connected to a cooling device 12 adapted to cool clinker in the absence of air i.e. either in water or water vapour or in a neutral or reducing atmosphere and a guiding device 5 situated at the outlet of the first cooler 4 and adapted to direct clinkers either towards the second cooler 7 or towards the heater 8, means being provided for supplying cooling air from the first cooler 4 as combustion-supporting air to the roasting kiln 3.

Filed: 1966-11-11
Abstract: 1,131,480. Fuel elements. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. 11 Oct., 1967 [11 Nov., 1966], No. 50760/66. Heading G6C. In a fuel element in which UO 2  is encased in a protective sheath, BaO is included within the sheath to form a trap for the I-131 fission product. Preferably the BaO is dispersed in a matrix, e.g. compressed stainless steel mesh or activated alumina, to provide a relatively large surface area. When used with a fuel element in which the sheath is completely sealed about the fuel, the trap is preferably positioned at the cooler end of the fuel element as fission products with their low vapour pressure will tend to collect there. Intermediate traps may, however, also be desirable, particularly if the fuel element is more than a few feet in length. The use of hollow fuel pellets is an advantage since the fission products then have a readier access to the trap. In the case of a vented fuel element, the trap may conveniently be provided in the vent path. The invention may also be applied to fuel elements which are connected internally to a He source and continuously purged, traps being provided to clean up the He which is recirculated. In vented fuel elements for a CO 2 -cooled reactor, an activated charcoal bed for trapping Cs and Te fission products may be used in addition to the BaO trap.

Abstract: 1493480 Making ethanol by fermentation; starch-producing algae C TATSUMI and M MURAMATSU 15 Dec 1975 51354/75 Headings C6E and C6F [Also in Division C3]  A method of producing ethanol involves aerobically culturing starch-producing unicellular green algae in a culture medium containing an organic compound providing a source of assimilable carbon, a source of assimilable nitrogen and inorganic salts and other factors necessary for the growth of the algae, repturing the cellular material to release intracellular starch, saccharifying the starch produced (extra-cellular and released intra-cellular), fermenting the saccharified starch in the presence of a saccharified starch-utilizing, ethanol-producing micro-organism (yeast) and recovering the ethanol produced from the fermentation medium e.g. by distillation. The strain of algae to be employed may belong to one of the following genera and species: Chlorella vulgaris, Chlamydomonas sp., and Scenedesmus basilensis, respectively. The morphological and cultural characteristics of three preferred strains are given. The strain of Chlorella vulgaris is capable of producing 70-80% of its dry weight of starch, intra- and extra-cellularly. The examples describe cultivating the algae on an industrial waste liquid rich in glucose or a culture medium containing acetic acid as the source of assimilable carbon, rupturing the cells by sonic treatment, saccharifying the starch by heattreatment in the presence of dilute sulphuric acid or saccharifying enzyme and fermentation of the saccharified starch with an alcohol fermentation yeast.

Abstract: 1,163,325. Shaft seals. FILTON Ltd. 17 Nov., 1966, No. 51614/66. Heading F2B. [Also in Division F1] A non-rotatable seal member 10 in a centrifugal pump (see Division F1) is held in contact with a rotatable seal member 9 by springs 25 when the pump impeller is stationary or rotating slowly. The springs may be coated with plastics, the member 9 may be of ceramic and the member 10 of glass powder or glass fibre reinforced polytetrafluoroethylene. During normal operation of the pump, auxiliary impeller blades 20 establish a liquid ring seal at the impeller periphery, and create a pressure differential across an axially-movable wall 13 so that the latter is moved towards the pump inlet 4 to thereby eliminate or relieve the pressure between the seal members 9, 10. An annular chamber S at one side of the movable wall 13 is sealed at its innermost end by a polytetrafluoroethylene diaphragm 21 clamped at its outer periphery by a washer 22 having concentric annular grooves in that face in contact with the diaphragm. The movable wall is secured to a plate ring 12 which may be of stainless steel and is prevented from rotating by a pin or pins 29 secured via rings 23, 24 to a part 14 of the pump casing. The movable wall 13 and casing part 14 are formed by moulding glass fibre bonded by polyester or other thermosetting resin, about a stainless-steel sleeve 11 and a stainless-steel ring 24 respectively, the sleeve and ring being knurled or otherwise formed to assist keying of the plastics. The unit comprising casing part 14, movable wall 13, seal member 10, ring 12 and diaphragm 21 may be readily removed, e.g. for access to the seal 9, 10.
