Title: Method for the heat treatment of fine granular material
IPC: C04B7/43
Filed: 1976-03-18
Abstract: 1495136 Heat treatment of granular materials POLYSIUS AG 18 March 1976 [22 May 1975] 10892/76 Heading F4B Fine granular material 6 is pre-warmed and heated in a preheater 1 by the hot exhaust gases 5 rising from a rotary kiln 2. The material 6 is repeatedly separated from the upwardly-flowing gases to form a dense stream of material moving down the wall of the preheater under the force of its own weight. This dense stream is reintroduced into the gas stream 5 by funnel portions 7 in the preheater so that at least part of the dense stream is again broken down by the oppositely moving gas stream. In the lowest section of the preheater 10 fuel 13 is supplied to the dense stream of material 12 moving down the surface 11. A certain portion of the stream of solid material immediately enters the kiln 2, while a greater portion 16 is entrained in the exhaust gases from the kiln and with the solid material again scattered in the gas stream, fuel burns on the individual particles of material or in the immediate vicinity of such particles.

Title: Flux valves
IPC: G01C17/30
Filed: 1973-03-07
Abstract: 1384659 Sensing magnetic fields SPERRY RAND CORP. 7 March 1973 [17 March 1972] 11060/73 Heading G1N A flux valve for use in a magnetic compass senses the total horizontal and vertical components of a unidirectional ambient magnetic field in which the valve is located. It comprises a non- magnetic central post 11 supporting three radially extending equiangularly spaced planar core legs 13 each of which includes a pair of inductors 14, 14' and a pick-up coil 15. A common excitation coil 16 is provided between the bifurcated ends of the inductors 14, 14'and arcuate shaped laterally directed flux collectors 22, 22' are mounted at the opposite ends to increase the density of the horizontal component of the ambient field. In order to sense the vertical component of the field three U-shaped extensions of the horizontal core legs 13 are provided each of which includes two high permeability magnetic material core legs 26, 26'which are arranged at equiangular positions around the central post 11 and mounted thereon. The collectors or core legs 26, 26'are energized by a further excitation winding 27 and separated together with core legs 14', 14 by insulation spacer 29. A further pickup coil may be mounted on an intermediate portion of each of the core legs 26, 26'. The pickup coils are connected in series in a Y configuration. In an alternative embodiment the collectors 22, 22'legs 13, pick-up 15 and excitation coil 16 may be omitted. A soft iron compensator 30 may be provided. Operation Fig.7. In use the valve is strapped in a craft with one of the core legs 13 aligned parallel to the longitudinal craft axis. Vertical field lines impinge on the lower vertical collectors 26, 26'and leave the valve by way of the upper horizontal inductors 14, 14'. Horizontal field lines are gathered by the collectors 22, 22'to be directed along the horizontal inductors. Due to the movement of the field lines across the pick-up coils at each saturation of the core legs a signal at twice the frequency of the excitation signal is obtained. Amplifier 39 is connected to all the pick-up coils to give the total vertical component of the ambient field whereas differential amplifiers 40 are connected as shown to the pick-up coils to give the longitudinal and lateral horizontal components of the field. These signals are processed in conventional manner to effect coordinate transformations accounting for the roll and pitch attitude of the craft and thereby provide desired heading information.

Filed: 1920-04-21
Abstract: 142,113. Kodak, Ltd., (Assignees of Altschuler, J., and Isnow, D.). Feb. 3, 1917, [Convention date]. Measuring. - Apparatus is described for printing on the edges of a film at regular intervals a series of numbers in. dicating the length of film with or without additional symbols and prior to using the film. The numbers are printed on to the film 120, Figs. 1, 2, and 3, from a filmnegative 47, having printed numbers 100 and moving at right-angles to the film 120, and the additional symbols are printed from interchangeable insertion-plates 104, 105, Fig. 2, fitted in the printing-bed. The apparatus 22 may be combined with a perforating - machine 12 and mounted by a dovetail-base sliding in the base 80. The mechanism is driven from the bevel-gear 13 of the perforator. The numbered film 47 is drawn from a roll 86, Fig. 3, over a slot in the top of the casing 11 and is fed by a sprocket-wheel 69 on a spindle 67 driven by the worm-gear 65, 66. The take-up spool 44 is driven through the bevel-gearing 63, 41 and the pulley-belt 43. The exposure-shutter 32 situated in the partitioned compartment 27 is driven from the pulley-wheel 42 by a spring-clutch 51 and wheel 50, so that the spindle 31 of the shutter can be independently turned by hand to adjust the phase of the shutter. The film 120 to be exposed is pressed on the printing-bed by a weighted plate 130 and the two insertion-blocks 104, 105, Figs. 5 and 6, can be introduced with additional symbols such as the date, in the apertures 106, which register with the slots 102, 103, Fig. 2, on either side of the centre slot 101 on top of the casing 11 through which the numbers 100 on the film 47 are printed. In order to ensure proper registration of the shutter-slot 83 with the slots 101, 102, 103, when the numbers 100 on the film are over the aperture, the whole machine 11 is moved to disconnect the bevel-pinion 17 and a squared head 62 can be turned to advance the film 47 through a pinion 60, the shutter being independently adjusted bv the head 50. In order to be able to rewind the film 47 on the spool 86, the sprocket-wheel 69 is coupled to the spindle 67 by a spring-clutch member 71, which has a ring of holes normally engaging pins 70 on the sprocket and is coupled to the shaft 67 by a pin 72, Fig. 8, on the shaft and a slot 73 in the member 71. To re-wind the film 47, the member 71 is pulled outwards and turned so that the pin 72 engages the flange of the member 71 and holds the member 71 from engagement with the pins 70, and the sprocket is free to turn when the re-winding key 90, Fig. 2, and gearing 88, 87 is turned.

Title: Process for dewatering aqueous suspensions
IPC: C22B1/02
Filed: 1957-04-05
Abstract: Aqueous suspensions of finely divided carbon black or predominantly organic material are flocculated by the addition of 0,01-5% by weight, based on the weight of suspended matter, of a water-soluble linear polymer having a molecular weight of at least 500,000 and comprising 45-100 mole per cent of at least one quaternary unit having the formula:  <FORM:0842910/I/1> wherein R is H or CH3, A is -(CH2)2-, -(CH2)3- or -CH2CH(CH3)-, R DEG  is b -hydroxyethyl, b -hydroxypropyl or g -hydroxypropyl, R1 and R2 are each methyl or ethyl, and X is an anion which may be hydroxyl, or a negative, salt-forming atom or radicle, with 0-55 mole per cent of units having the formula:  <FORM:0842910/I/2> wherein A, R, R1 and R2 are as defined above.  Instead of the polymer itself, a water-soluble salt of such a polymer with an acid, or a water-soluble quaternary ammonium salt of such a polymer, may be employed.  The term "water-soluble" is used to denote that the material forms either a true or a colloidal aqueous solution.  After the addition of the polymer or the derivative thereof, the water is removed, for example by filtration, sedimentation or decantation, under such conditions that the water remains in the liquid phase throughout the removal. The salts of the polymer may be those of any organic or inorganic acid, such as hydrochloric, sulphuric, phosphoric, formic or acetic acid or any other fatty acid.  The quaternization agents used in forming the quaternary ammonium salts may be any of methyl chloride, ethyl chloride, benzyl chloride, alkyl chloride, corresponding bromides or iodides, phenoxyethyl bromide, dimethyl sulphate, dimethyl sulphite, dimethyl phosphite, ethylene oxide, propylene oxide, styrene oxide and butylene oxide.  The flocculating agents may be used for facilitating the dewatering of industrial wastes (e.g. from dairies of canneries), distillery wastes, fermentation wastes, wastes from paper-manufacturing plants, wastes from dyeing plants and sewage sludges (e.g. digested or activated or raw sludge or mixtures thereof).  In the examples, the aqueous suspensions treated are digested sewage sludge, an aqueous suspension of furnace black (formed with the aid of a condensate of formaldehyde and sodium naphthalene sulphonate as dispersion agent) or an aqueous suspension of a yellow dyestuff (Carbanthrene Yellow G Double Paste).  The flocculating agent is a homopolymer of b -(N, N-dimethylamino) -ethyl methacrylate, particularly quaternized with ethylene oxide or propylene oxide and then converted to its phosphoric acid or acetic acid salt.  In one instance, the flocculating agent is used in conjunction with ferric chloride and lime.  Tests are described in which the effect of the flocculating agent is compared with that of polymerized acrylamide, the sodium salt of 70% hydrolyzed polyacrylonitrile or mixtures of ferric chloride and lime.
