Title: Method of agglomerating iron ores
IPC: C22B1/20
Filed: 1970-11-27
Abstract: 1333950 Agglomerating ores ACIERIES REUNIES DE BURBACH-EICH-DUDELANGE SA 27 Nov 1970 [27 Nov 1969] 56530/70 Heading C1A A method of agglomerating iron ores on a moving grate is characterized in that the ore is agglomerated in two layers on the moving grate, the CaO/SiO 2  indices of which are respectively at least 0À15 point above and below the mean final basisity of the desired product. The iron ore to be agglomerated may be constituted by an ore of a single type rich or poor in iron, or a mixture of ores rich and/or poor in iron. Either or both of the layers may contain a portion of returned fines and other ingredients such as lime, limestone or dolomite fluxes. A preferred mean final basisity is 1À35 Œ 0À4 which may be obtained by agglomerating equal quantities of ores having initial basisities of 0À9 and 1À8. The thickness of either layer may be between 20 and 80% of the total height of the agglomeration batch.

Abstract: 1392230 Doppler navigation; ultrasonic couplings; acoustic lenses THOMSON-CSF 15 Dec 1972 [17 Dec 1971] 58094/72 Headings H4D and H4J In an aquatic vessel acoustic wave Doppler navigator, the transmit and receive transducer pairs are mounted in a casing containing fluid which is temperature controlled, to remove the dependence of the Doppler shift frequency on the progation velocity of the acoustic waves in the vessel bearing water. In a Janus-type acoustic Doppler navigator transmitting elements 5 are mounted on arms 14 attached to an acoustic lens 9. The lens comprises two hemispheres 10, 11 of acoustically transparent (polyurethane) and absorbing material (rubber/cork) respectively. The lens contains a fluorocarbon fluid 12 and is connected via a duct with an expansion chamber 13. The transmit and receive elements 5, 6 are stabilized against pitch and roll by being suspended from cover 16 by a pendular arrangement 15 containing universal joints.

Abstract: 1382158 Television WESTINGHOUSE ELECTRIC CORP 18 Dec 1972 [18 Jan 1972] 58330/72 Heading H4F  Video signals derived from a scene by a visual radiation sensor and an infra-red radiation sensor are displayed on a colour television display device, the visual video signals being displayed as a black and white image and the infra-red video signals as a colour image superimposed thereon, and the infra-red video signal having its amplitude varied as a function of the D.C component of the visual video signal so that the displayed hue of the infra-red image is not influenced by the amplitude of the visual video signal. The display device may comprise a two or three gun colour C.R.T. display tube, and the sensors image pick-up tubes. In the embodiment described the visual video signal is applied to the red, green, and blue guns of a colour C.R.T. display so that a black and white image is displayed in the absence of the infrared video signal, and portions of the infra-red vidoe signal corresponding to high temperature objects in the scene are arranged to increase electron emission from the red gun and decrease electron emission from the green and blue guns (these portions comprise positive portions with respect to a selected reference level in the video signal), whereas portions (negative portions) of the infra-red video signal corresponding to low temperature objects in the scene decrease the red emission and increase the green and blue emissions. An image corresponding to the infrared radiation is displayed when no visual video signal is present. The infra-red sensor may comprise a mechanical scanner, e.g. rotating mirror or prisms, and an array of infra-red detectors. The display device may comprise a "Chromatron " or " Trinitron " (Registered Trade Marks).

Title: Recovery of cephalothin salts
IPC: A61K31/546
Filed: 1971-12-20
Abstract: 1318690 Cephalothin salts ELI LILLY & CO 20 Dec 1971 [24 Dec 1970] 59068/71 Heading C2A Alkali metal salts of 7-(2<SP>1</SP>-thienylacetamido) cephalosporanic acid (i.e. cephalothin) are recovered from aqueous solutions thereof by adding a non-toxic alkali metal salt to the solution to precipitate the cephalothin salt and separating the precipitate thus formed. Preferred alkali metal salts are those of an acid having a pKa of less than 5, e.g. alkali metal bromide, chloride, acetate, citrate, lactate, maleate, fumarate, gluconate and glutarate. The alkali metal (e.g. Na, K or Li) is preferably the same as the cation of the cephalothin salt. The alkali metal salt may be added in solid form or as a concentrated solution in water or an alkanol (e.g. ethanol, isopropanol or butanol), or a mixture thereof, and is employed in an amount ranging from 0À5-8À0 parts by weight per part of the cephalothin salt in the solution. The cephalothin salt solution is preferably fairly concentrated, e.g. from 10% by weight to saturation concentration. The process results in a purified cephalothin salt free from coloured impurities and having improved stability in aqueous solution. Pharmaceutical compositions having antibacterial activity comprise an alkali metal salt of cephalothin when prepared by the inventive process and a pharmaceutical carrier.

Patent GB-753289-A (GB)
Abstract: 753,289. Calculating-apparatus. FELT & TARRANT MANUFACTURING CO. Aug. 6, 1954 [Sept. 1, 1953], No. 22906/54. Class 106 (1). Coloured transparent material overlies certain denominational orders of the accumulator wheels in order to point-off the results registered. Preferably, and as shown, the material is in the form of a slide 28 adjustable transversely of the machine by means of fingerpieces 36, so that the colour grouping can be adjusted according to the location of the decimal point. The slide is dimensioned to overlie and colour (green) three orders on either side of an aperture 39 which also extends over three or less. With the finger-pieces 36 and slide 28 adjusted to their right-hand position, the lowest order totalizer wheel is left uncoloured to represent decimal fractions, whilst the wheels to the left present, alternating coloured and uncoloured groups of three. When, as in decimal currency calculations, the two lowest orders are used for decimal fractions, the slide is shifted to its central position which leaves those two or less uncoloured whilst shifting the colour grouping of the remaining orders correspondingly one step to the left. In its left-hand position, the slide similarly effects a colour grouping for representing the three lowest orders either as decimal fractions or as units tens and hundreds. In Figs. 1 and 6, conventional decimal point indicators are provided, comprising pivoted indicator elements 21 situated between adjacent numeral wheel apertures 18 and which can be adjusted to display a coloured mark at windows 19 by operating respective finger-pieces 24. Alternatively, the slide may be provided with extended portions 42, Fig. 5, adapted to appear at the windows so as to mark both the decimal point and the other usual marking-off points. The slide is accommodated, together with a clear transparent strip 27, between the underside of the machine cover 11 and a frame plate 31 secured to the cover. Specification 633,957 is referred to.
Patent GB-2026872-A (GB)
Title: Electronic matching game
IPC: A63F9/18
Filed: 1978-06-23
Abstract: An electronic game comprises selection means arranged for each of two players to set up separate display means having two different states of each of a number of display devices, and comparison means to give an indication or indications of their equality and/or their inequality. Overriding means is arranged so that each player can at will, in respect of a number of the said display devices, hold each in a preselected one of its said two different states. The electronic circuitry is so arranged that, if one display is in the form of red or green colours of a first group of "lamps" (light-emitting-diodes devices), then the other player can attempt to set up an identical display of a second group of the "lamps". The comparator is arranged to automatically give audible and/or visible signals according to the result of the comparison. The other player can decrease the statistical difficulty of his task, by pre- setting the state of some of the "lamps" of the second group. Integrated circuits may be employed. <IMAGE>
