The delivered cement powder heated by the gas is centrifugally separated from the gas in the chamber 1 and is discharged to a rotary kiln through outlet 16 as the gas is extracted axially from the chamber through a main offtake 3 and the said offtake 4. In a further embodiment, several of the devices are used in series and compressed air is used instead of hot gases for fluidizing the cement.  In another embodiment, the cement is fluidized by the injection of superheated steam, or by a combination of steam and air, or steam and hot waste gas.

Patent GB-724837-A (GB)
Title: Trigger circuit
IPC: H03K3/12
Filed: 1953-04-15
Abstract: 724,837. Pulse-generating and discriminating circuits. ATOMIC ENERGY OF CANADA, Ltd. April 15, 1953 [April 28, 1952], No. 10334/53. Class 40 (6). In a triggered pulse generator, feedback is arranged over a biased rectifier from a dynode to the control grid, the bias allowing the tube to operate under class A conditions. A second feedback circuit for D.C. is arranged over a second valve to ensure constancy of operation. The input pulse may be fed over a biased rectifier to give a discriminating action. In the absence of an input pulse, tube V1 conducts to the dynode and feedback occurs over capacitor C3 and the self-capacity of rectifier X2; the attenuation due to the ratio of control grid to cathode capacity to rectifier self-capacity being such that the loop gain is less than unity. The standing potential of the grid is determined by that of the cathode of tube V2 since rectifier X3 is conducting and the potential of the grid is determined by resistor R10, R12 connected to the anode-feed resistors R1, R2 of valve VI. A rise in grid potential of valve V1 results in a fall in the anode potential which is transmitted by valve V2 operating as a cathode follower to reduce the variation in the grid potential of valve VI. The rectifier X2 is biased to its non-conducting state by a potential derived from the potentiometer R13, the setting of which determines the sensitivity of the device. A positive-going input pulse of sufficient amplitude causes rectifier X2 to conduct due to the resulting rise in dynode potential, the loop gain becoming greater than unity. Heavy current flows from the cathode and maintains saturation between dynode and anode, the rise in dynode potential carrying the control grid into the grid-current region. The control grid and cathode currents then fall with the loop gain less than unity. When the flow of current is insufficient to maintain dynode saturation, the control grid becomes effective and the loop gain exceeds unity, the rectifier becoming non- conductive during this period of operation, the feedback being maintained by its self-capacity. By biasing the rectifier X1 by a potential from potentiometer R15, the circuit may be used as a discriminator. The self-capacitance of the rectifier X1 may be minimized by feeding a negative push-pull input over a capacitor C11 and resistor R19 equal to the self-capacity and back-resistance of the rectifier.

Title: Improvements in or relating to hydrostatic transmissions

Abstract: 952,565. Hydraulic transmission of power. FORD MOTOR CO. Ltd. Feb. 5, 1963 [March 19, 1962], No. 10346/62. Heading F2C. An hydrostatic transmission comprises a variable and reversible delivery pump C operating a variable capacity motor D, in which the pump and motor swashplates are actuated by follow-up double acting rams 11, 12, the ram valves 19, 20 being controlled by links 15, 16 extensible and compressible from their normal lengths and connected to lever arms 6, 7 simultaneously rotatable about a fixed pivot to operate the valves in a desired sequence. The lever arms 6, 7 are rotated by rack-andpinion mechanism 2, 3 and lever 1 such that the speed ratio is varied in a forward and reverse direction such that the pump swashplate angle is varied up to a maximum while the motor swashplate is maintained at maximum angle, followed by a reduction of the motor angle with maintainance of the pump angle at maximum as described in Specification 866,609. The maximum swashplate angles are determined by stops 21, 22, 23 which contact the valves 19, 20 of the servo-rams, the spring-loaded links 15, 16 allowing an over-centre movement corresponding to the neutral position, such that initial movement from the position first allows the link to return to normal length then to adjust the swashplate angle. The fluid for the rams may be derived from a fixed displacement pump, or from the transmission with or without a make-up pump, through a flow restriction. The rams may be fed in series or parallel.

Title: Improvements in ferromagnetic materials and processes for their preparation
Inventor: OPPEGARD ALFRED LESTER
IPC: G11B5/706
Filed: 1959-03-25
Abstract: A ferromagnetic material comprises tetragonal crystals of chromium oxide containing as an integral part a modifier consisting of one or more of the elements Ru, Sn, Sb, Ti, V, Mn, Fe, Co, Ni and F.  The material comprises 42.5 to 61.9% by weight of chromium and 0.008 to 25.0% of the modifier.  Further modification can arise by the additional inclusion of elements from the group N, P, As, Sb, Bi, V, Ta, Pa, Cd, Li, Na, K, Cs, H, Mg, Zn and Pd.  The different modifiers provide a diversity of properties, e.g. coercivities may be above 400 oesteds and Curie temperatures between 80 DEG C. and 170 DEG C.  With Ru, Sb and Sn acicular particles 2 m  in length and having an axial ratio from 4:1 to 35:1 are obtained and exhibit high coercivity.  Low coercivity is obtained with Ni and Co, the particles having irregular shape and an axial ratio from 1:1 to 6:1.  Fluorine, which replaces oxygen in the crystal structure provides irregular particles less than a micron across.  The material is prepared by heating CrO3 with the modifying elements or compounds thereof at 225 DEG C.-500 DEG C. and pressures of 1-3000 atmospheres. Amongst suitable modifier compounds specified are oxides, acids bases, salts, sulphides, sulphates, halides, carbonates, and nitrates.  Fluorine may be introduced as HF or metal fluoride. The reaction which may last from 10 minutes to 3 hours may be carried out in water steam or a molten salt such as lithium nitrate.  Oxygen is evolved and the product corresponds to a modified chromium dioxide.  The processing equipment is of platinum or Ni-Cr-Fe alloy to be resistant to O2.  The product obtained after heating is generally filtered, washed and dried.  The materials are suitable for recording media, permanent magnets, transformer cores and memory devices.  In one example CrO3, Sb2O3 and water are hermetically sealed in a platinum tube with flexible walls which is subjected to a pressure of helium of 700 atmospheres and heated for 3 hours at 400 DEG C.  The antimony modified chromium oxide produced is boiled in water and dried.  For a recording tape this material is dispersed in a toluene/butyl alcohol mixture containing acetyldimethylamine, milled, added to a solution of polyvinyl butyral, remilled, filtered, degassed, coated on to a 1 mil polyethylene terephthalate tape either in or in the absence of a magnetic field, and dried to give a magnetic coating of 0.65 mils. Specification 824,323 is referred to. p
