Title: Continuous purificn. of petroleum refinery effluents - by biological oxidn. and aeration between stages
Filed: 1975-06-13
Granted: 1979-10-30
Abstract: Activated sludge treatment of effluents from chemical factories, and partic. those from petroleum refineries, is effected in four stages: (1) primary treatment by sedimentation; (2) intermediate treatment by equalisation, pH adjustment, coagulation, oxidn. and filtration; (3) secondary treatment by aeration between the stages, biological oxidn., clarification, thickening and aerobic digestion; (4) tertiary treatment by coagulation/flocculation, filtration and adsorption on activated carbon. The refinery effluent enters the plant at the sump and then into a conventional separator where considerable quantities of oil and solids are eliminated. The chemical effluent enters at compartment of the multi-compartment tank. The mixed effluents pass through pipes, to press. filters and to the biological treatment section; this comprises four stages, a contract stage where the effluent meets the activated sludge, a clarification stage, a thickening stage and a digestion stage. The decomtanminated water then flows through a second battery of filters and is rejected into a watercourse. When rejected the evacuated water contains at least 5 ppm. of dissolved oxygen so that it does not therefore lower the quality of the receiving stream. Biological degradation is improved by keeping the temp. in the equalising tank at 32.2-37.8 degrees C.

Granted: 1988-02-10
Abstract: The graphic system includes a framestore (21) and a pipeline brush processor (22). Image pixels are read out of the framestore in batches and applied to an input of the brush processor. Other data representing colour shape and pressure of a line drawn by a user on a touch tablet (17) by way of a stylus (18) is also input to the processor. As the pixels pass through the processor they are modified by the other data. Batches of modified pixels are written back to the framestore. The reading and writing of pixels from the framestore (21) is interleaved with the reading of pixels for display as an image on a monitor (16). The system also includes an arrangement for interpolating stylus pressure to remove visible discontinuities or other changes in the drawn image resulting from significant changes in stylus pressure.

Abstract: The plastic bubble packaging film is manufactured by bonding together two sheets of high density polyethylene (F1, F2) along two sets of joint lines set at right angles to each other and forming a network of sealed envelopes (14) that encapsulate the bubbles. The bond is effected in two successive stages by two pairs of fluted rolls (1a-1b, 7a-7b), one profiled circumferentially, the other axially, between which the sandwiched sheets are caused to pass. The surfaces of the rolls are heated in order to soften the sheets along the joint lines and enable the bond. On passing through the first pair of rolls, lenghtwise seals are effected so as to form tubular envelopes (13) into which air is blown, whereupon the smaller envelopes (14) are sealed off and the bubbles encapsulated by the transverse action of the second pair of rolls.

Abstract: 905,253. Ceramic glass. CORNING GLASS WORKS. June 30, 1960 [July 1, 1959; May 18, 1960], No. 23000/60. Drawings to Specification. Class 56. [Also in Group XXXVI] A semi-crystalline ceramic body intended for use as a dielectric comprises, as to at least 30- 90%, the constituent oxides of at least one oxygen octahedra ferro-electric compound, at least 30% of the body being in the form of a crystalline phase uniformly dispersed in another phase, being crystallized in situ from a homogeneous glass, the body containing at least one glass-forming oxide. The percentages quoted are " cationic mol." figures, i.e. figures calculated in respect of molecules, or part molecules, containing one cationic atom, e.g. SiO 2 , AlO 1 . 5 . The glass-forming composition is melted, cooled and heat-treated to crystallize it. The temperature at which crystallization occurs is determined by " differential thermal analysis," i.e. observing discontinuities in the rate of change of temperature, during heating, as a result of endothermic and exothermic processes occurring in the glass. The optimum heat treatment temperature is mid-way between the crystallization temperature and about 50 ‹ C. below the melting temperature which can be similarly determined. The length of treatment decreases with increasing temperature. The preferred oxygen octahedra ferro-electric compound is barium titanate and the initial composition for this purpose contains 30-15% BaO, 15-10% TiO 2 , the amount of BaO being 0-100% in excess of the 1/1 stoichiometric equivalent of BaTiO 3  on the amount of TiO 2  present, 7-26% SiO 2 , 3-30% AlO 1.5 , the amount of AlO 1.5  not differing from the amount of SiO 2  by more than about <SP>4</SP>/ 3  of the amount of SiO 2  and 0.5 to 1.5% F, the total of BaO, TiO 2 , SiO 2 , AlO 1.5  and F being at least 90%. Other oxides which may be added are those of K, Li, Be, Mg, Ca, Sr, Zn, Cd, Ga, In, Ti, Y, La, Ce, Zr, Ge, Sn, Sb, Bi, V, Nb, Ta, Cr, Mo, W, Te, U, Mn, Fe, Co, Ni, Pb, Cu. Other compositions are given in which the glassforming oxide used instead of, or in addition to, SiO 2  is B 2 O 3  or P 2 O 5 . Further compositions are given which form a body in which the ferroelectric compound consists of one or more of:- titanate of barium or cadmium; niobate of sodium, potassium, strontium, cadmium, barium or lead; zirconate of cadmium, barium or lead; tantalate of sodium or cadmium; ferrate of lead or lanthanum; germanate of iron; tungstic oxide.
