If the side dams 14, 16 (blocks 18 slotted on metal straps 22) are moved apart to cast a wider copper bar, in the first embodiment, the backing rollers 24A are removed and replaced by rollers with correspondingly relocated collars 36. Streams of coolant water, indicated by arrows, from nozzles fed through conduits 27, are applied at an angle to the backs of the belts to provide a water layer flowing between the rollers 24A or 24B and the belts and longitudinally of the latter. Streams 29A are aimed into the grooves 40, if provided, to cool the belts in the side dam zones. In the second embodiment, Fig. 7, the longitudinal supporting elements 48 are mounted on transverse members 52 extending between side frames 53, 54 on which the bearings of the backing rollers 24B are mounted. The elements 48 have tapered ends 62 curved to match the main belt-rolls, and surfaces adjacent the belts are coated with bearing bronze metal and lubricated with graphite or other dry lubricant.

Title: Production of balls or spheres of refractory materials
IPC: B01J2/08
Filed: 1964-05-20
Abstract: Spheroidal oxides or carbides of U, Th, Pu, Be, Al or Mg or mixtures thereof, are produced by mixing an acidic solution of a compound of the corresponding metal, with or without carbon, with a cellulosic derivative which increases in viscosity in the presence of alkalis, dripping the resultant mixture into an aqueous alkaline solution, and washing, drying, and calcining the spheres so produced.  The acidic solution may have a metal concentration of 0.1-2 moles/l. In the example, a mixture of U and Th chlorides is used.  If carbide is to be produced, dry colloidal graphite or carbon black is added in a metal/carbon ratio of 1/4 to 1/5 .  The cellulosic derivative may be hydroxypropyl methyl cellulose stabilized with polyethylene glycol and is added in proportions of 0.5-5 g./100 ml. of mixture.  The mixture may be dripped from a 1 mm. hole into a tube 30-50 cm. high containing alkali, e.g. NaOH, NH4OH, N2H4, NH2OH or monoethanolamine, of concentration 1-20 moles/l.  The spheres are aged, dried at 80-100 DEG  C., and calcined at 1000-1300 DEG  C. for oxide, or above 1600 DEG  C. in vacuo for carbide.

Title: Colour signal decoding
IPC: H04N5/06
Filed: 1971-04-19
Abstract: 1342913 Colour television MOTOROLA Inc 19 April 1971 [5 Feb 1970] 20923/71 Heading H4F A photographic film, magnetic tape or embossed strip has luminance and chrominance information on adjacent frames, the chrominance information being recorded in the form of (for films) alternate opaque and transparent stripes, the width of the transparent stripes representing colour saturation, every second transparent stripe representing R-Y colour information, the intervening stripes representing B-Y colour information. The film 10 is scanned by a flying spot scanner 30 and the output chrominance signal 65 is passed to a clamp circuit 66 which clamps one set of peaks of signal 65 to provide signal 67 which is passed to a differential amplifier 75 and an envelope detector 70, half the output from which is also fed to amplifier 75. The resulting output is clipped and passed to a differentiator 80, the output from which controls a multivibrator 90 and phase splitter 92, to control gates 82, 84 to pass red and blue colour difference signals respectively, which are then integrated in circuits 102, 104. To achieve synchronization at the start of each line, trigger 124 is set by a horizontal retrace pulse 120 to interrupt the operation of multivibrator 90. The trigger 124 is reset and multivibrator 90 started by the next pulse from amplifier 75, which is one of a number of pulses recorded at the start of each line in phase with the red colour difference signals. Shading of the output luminance signal is compensated for by taking the output of envelope detector 70 and feeding it to scanner 30 to control the brightness of the raster, or to a shading circuit 114 which shades the chrominance signals the same as the corresponding luminance signal. In an alternative embodiment (Fig. 4, not shown) the negative output pulses of the differentiator 80 are passed by the gates 82, 84 instead of the chrominance signal, the gating signals 94, 96 from phase splitter 92 being integrated, and gated to the output of the apparatus when a pulse is received from gate 82 or 84, the amplitude of this integrated signal being a measure of the width of the associated stripe. In this case trigger 124 is reset by an oscillating signal built up in a resonant circuit by the recorded synchronizing pulses.

Abstract: A water-dispersible veterinary preparation comprises (a) up to 50% by weight of a therapeutically active substance, (b) from 2 to 70% by weight of a polyethyleneglycol which is solid at room temperature and (c) from 10 to 70% by weight of an amphiphilic agent which is solid at room temperature, the preparation being in the form of particles, the major portion of which have a diameter within the range of 50-200m .  The polyethyleneglycol may have an average molecular weight of 2,000-10,000.  The amphiphilic agent may be a monoglyceride of a C12-20 fatty acid, or a mixture of mono- and di-glycerides of such an acid, a C12-20 fatty alcohol, a C12-20 fatty acid or an amide of such an acid, or a mixture thereof.  The therapeutically active substance may be a sulphonamide, e.g. sulphisoxazole, sulphadimethoxine, an antibiotic, e.g. chloramphenicol, neomycin, or other drug, e.g. chlorprothixene, chlordiazepoxide, diazepam, 1,4-bis(trichloromethyl)-benzene, chlorpromazine, aminophenazone, a barbiturate, chrysazin salicylate, chloral hydrate, hexamethylene tetramine, a plant extract, e.g. quinine, caffeine, opiates, aloe, kamala, croton oil, arecoline, as well as iron, arsenic, cobalt, manganese, zinc, and mercury compounds, iron and vitamin compositions.  Therapeutically active liquids may be adsorbed on solid carriers.  The wettability of the particles may be improved by addition of known wetting agents, e.g. soap or non-ionic polyglycol. The powders may be dispersed in water or milk for oral administration to aminals.  The flowability of the powder may be improved by the addition of ca3(PO4)2.  Conventional fillers, aroma-imparting materials, and excipients may be added.  The preparations may be made by mixing the essential ingredients at a temperature above the melting point of the polyethylene glycol and amphiphilic agent and spray drying to the requisite particle size, or alternatively solidifying and grinding to such size.

A space heating stove which may be used to discharge hot air into a room and to supply hot water comprises a chamber 1 provided with a burner 3, an air inlet (not shown) adjacent the burner, an air outlet 2, and a water tank 6 disposed within an open-ended chamber 4 as shown in Fig. 2. The flow of combustion products and heated air from the burner is controlled by a damper 6 which if open allows the hot gases to pass through chamber 4, thus heating the water tank and if closed causes gases to flow as indicated by the arrows, thus additionally heating the room air through the walls of the chamber 1 without heating the water. The damper may be adjusted to intermediate positions to vary the heat supplied to the water. In the embodiment of Fig. 4 the water tank is above chamber 4 and a damper 14 controls the gas flow, closing either an aperture 11 or the top of the chamber 4. In the former case the water tank is heated and in the latter the gases pass via duct 10 to the outlet 2 by-passing the water tank. In the further embodiment of Fig. 6, the water tank is enclosed in an insulating cylinder 19 and a damper allows hot gases to pass either through the insulating cylinder or through the outer chamber 16 to by-pass the water tank. In all embodiments, the dampers may be thermostatically controlled to provide a desired water temperature.
