Abstract: 318,319. Concordia Bergbau-Akt.- Ges., Bronn, J. I., and Fischer, G. June 9, 1928. Materials for purifying.-Coke-oven gas to be compressed and cooled below 100' C. is previously washed at a higher temperature and a pressure not above 30 atmospheres with concentrated ammonia and acetone or other organic acetylene solvent of low freezing point. Gas from the oven 1 deposits tar in the receiver 2, and is cooled to normal temperature in a condenser 3, moisture and further tar collecting in a tank 4. The gas passes to a tank 5 and is drawn therefrom by a multi-stage compressor 6 with intermediate cooling, naphthalene and anthracene depositing in separators 7. Further cooling is effected at 8, and benzol is collected in a tank 9. The gas then passes through ammonia washing towers 10, 11, 12, the ammoniacal liquor and the remaining benzol passing into a tank 17 and being further treated. The ammonia is cooled by coolers 18. Washing with acetone is effected in towers 19, 20, the solution passing to a tank 23 for regeneration. The gas is further washed with acid in a vessel 24, and the vapours of the washed liquids are removed in a vessel 28 by soda lime, charcoal, or silica gel. Finally the gas is cooled to a low temperature in one of the coolers 30, 31 arranged in parallel; condensate passes to separators 32, and the gas flows to the separation apparatus 34. The washing towers may be arranged in parallel; cooling may be effected by use of brine, evaporating ammonia, or gases from the separator 34. An incrustation of ammonium salts is prevented by adding paraffin oil &c. to the ammonia. The ammonia and acetone may be used as a mixture. Liquefied ammonia gas may be used for the ammonia washing.

Abstract: 1,057,213. Concentrating ores. AMERICAN AGRICULTURAL CHEMICAL CO. April 21, 1965 [May 6, 1964], No. 16846/65. Heading B2H. Phosphate rock is beneficiated by subjecting feed phosphate rock contaminated with siliceous material to a wet grinding operation to yield a ground phosphate rock leaving a particle size smaller than about 14 mesh (Tyler scale), selecting a fraction of the ground phosphate having a particle size greater than 325 mesh and subjecting it to a cationic flotation operation whereby the siliceous contaminant material is floated off and a concentrate having a phosphate content higher than that of the feed phosphate rock is recovered. The flotation operation is a froth flotation one carried out in the presence of a cationic amine flotation agent. Additional reagents employed in the flotation operation are caustic soda and kerosene. In one embodiment, the various steps of which are illustrated in the flow chart of Fig. I, deslimed phosphate rock is wet ground in a rod mill to pass through a 28 mesh, or preferably 35 mesh, screen. The ground rock is classified to remove the - 150 mesh fraction. The remaining - 28 to +150 major fraction is subjected to amine-flotation for the separation of siliceous materials which may be discarded as tailings or waste. The resulting concentrate having an increased phosphate content is recovered as product. The - 150 mesh ground fraction is thickened, filtered and subjected to chemical treatment such as by reaction with sulphuric or phosphoric acid to yield a phosphate fertilizer material. In another embodiment, Fig. 2, (not shown), phosphate pebble is treated and the - 150 mesh fraction is either acidulated to yield fertilizer material or pelletized to yield a phosphorous furnace burden. In a further embodiment, Fig. 3 (not shown), in which also phosphate pebble is treated, a -14 mesh fraction is passed through a 35 mesh screen. The -14 +35 mesh fraction is subjected to amine flotation. The -35 mesh fraction is passed through a 150 mesh screen. The -35 +150 mesh fraction is subjected to amine flotation and the -150 mesh fraction is filtered and recovered as furnace burden after pelletization or as fertilizer material after drying or acidulation. The -150 mesh fraction in any of the above embodiments may be further segregated into higher -mesh fractions and each fraction subjected to amine flotation. Quantitative examples are given.

Title: Improvements in toys with detachable and adjustable, or interchangeable parts
IPC: A63H3/10
Filed: 1920-06-23
Abstract: 155,183. Fithian, F. L. June 23, 1920. Building-blocks and the like.-Relates to toys built up from interfitting sections and consists of means by which the sections are frictionally held in position when put together. In the figure shown in Fig. 1, the body of flat material has two slots 5, Fig. 5, cut in each end parallel with the sides, thus forming a central tongue 7 and two side plates 6. The legs 13, and the limbs are similarly formed with a single slot 14, thus forming side plates 15. The plates 15 are bevelled at the ends, as at 18, and the width of the member 13 is slightly greater than the distance between the. inner surfaces of the side plates 6 of the body portion. Thus when the plates 15 are forced into the slots 5, as shown, the plates 15, 6 bend slightly and the member 13 is held in position by friction. If desired, the body may be formed with a single slot, thus dispensing with the central tongue 7. Alternatively, the width of the member 13 may be slightly less than the distance between the plate 6, but in this case, the tongue 7 is wider than the slot 14, thus bending the plates 15 outwards when the members are fitted together. Various figures and animals with interchangeable parts can be formed in this way, and blocks 1<c>, Fig. 10, slotted at the edges as described, can be connected by key-pieces 20, acting similarly to the member 13.

Title: Improvements in gas turbine systems
IPC: F02C6/00
Filed: 1944-09-08
Abstract: 592,081. Fluid-pressure servomotorcontrol systems. AKTIEBOLAGET LJUNGSTROMS ANGTURBIN.. Sept. 8, 1944, No. 17148. Convention date, Jan. 28. [Class 135] [Also in Group XXVI] A gas turbine driving a compressor is controlled through a servomotor by the discharge pressure of the compressor. The throttle valve 62 in the intake duct 46 of the turbine is operated by a servomotor 68, the control piston 74 of which is balanced between the pressure in a diaphragm 78 and a spring 80. Any change of pressure in the diaphragm causes the control piston to move and allow pressure oil to pass from the pipe 84 to one side or the other of the piston 66 and so open or close the valve 62 to alter the speed of the turbine and bring the pressure at the discharge of the compressor back to the required value. The pressure required can be pre-set by means of the hand wheel 82 which increases or decreases the compression in the spring 80. The throttle valve 62 can be replaced by means whereby some of the turbine nozzles are cut in or out of service. In a plant employing high pressure *and low pressure turbines driving high and lowpressure compressors, the discharge pressure of both compressors may be used conjointly to control the low-pressure turbine.

Title: Improvements in or relating to wireless direction-finding systems
IPC: G01S1/02
Filed: 1931-06-15
Abstract: 380,466. Directive wireless signalling. LEVY, L., 5, Rue du Cirque, Paris. June 15, 1931, No. 17380. Convention date, June 13, 1930. [Class 40 (v).] In a wireless direction-finding system of the rotating beacon type the azimuth is defined by the comparison of the intensities of two mutually perpendicular beams of waves modulated at different frequencies, which frequencies vary continuously with a different law of variation for each beam. The arrangement for producing one of these beams is shown in the Figure and comprises an aerial system 1 .. 8 consisting of two horizontal aerials 5, 6 and 7, 8 as described .in Specifications 233,346 and 251,638, [both in Class 40 (v), Wireless signalling &c.]. These are connected to the fixed goniometer coils 13, 14 respectively, fed from a rotating coil 15 connected to the transmitter 23 which receives radio frequency from a source 22 and audio frequency for modulation from a source 21 whose frequency is cyclically varied by a variometer 19, 20 mounted on the goniometer shaft. To produce the second rotating beam with different audio frequency characteristics, another rotating goniometer coil is mounted perpendicular to coil 15 and supplied with radio frequency currents from the same source but modulated by a second variable audio frequency source. Each direction is thus characterized by a given pair of audio frequencies heard at the same intensity at the receiver. The acoustic frequency circuits at the receiver may be tuned by variable condensers having the same law of variation as a function of the angle of rotation as the audio frequency circuits at the transmitter which may also be varied by condensers instead of variometers The receiver may comprise tuned reeds or a pair of milliammeters whose pointers are arranged to cross on a fixed line, Fig. 2 (not shown), when the receiver is on the desired route. When laying out an aerial route utilizing beacons according to the invention, similar projectors of limited range are placed at each bend of the route and emitting, towards the zenith, successively, the two acoustic pairs corresponding to the portions of the route on either side of the bend. The Specification as open to inspection under Sect. 91 (3) (a) comprises also systems in which is emitted a single rotating beam of light or wireless radiation some characteristic of which varies with the direction of emission. In the case of light, the colour, the polarization, the frequency of interruption, the intensity or the frequency of variation of the polarization of the beam may be varied. Thus, for example, a lamp may be arranged in a glass cage coloured with different coloured bands in different azimuths. It also comprises a system of defining a route r, Fig. 2 (Cancelled), the route being the locus of points defined by the intersection of beams of predetermined acoustic frequencies from transmitters R. This subjectmatter does not appear in the Specification as accepted.
