Title: Improvements in apparatus for the manufacture of superphosphate of lime and similar compounds
IPC: C05B1/10
Filed: 1920-03-03
Abstract: 139,803. Chemical Construction Co., (Assignees of Forbis, R. E.). March 4, 1919, [Convention date]. Calcium superphosphate. - The apparatus is constructed so that the materials may be mixed, allowed to " condition " as long as may be necessary, and finally removed by some form of conveyer, in one continuous process. The thin pasty mixture of ground phosphate rock and sulphuric acid, or other materials requiring similar treatment, is discharged from the mechanical mixer 12, standing on the fixed cover 6, into the slowly revolving annular " den " or container 8, and is carried three quarters of the way round the track 10 to the stationary excavator and elevator 13, by which time it has become sufficiently conditioned to be removed. The den is caused to revolve, but it must be capable of being stopped or accelerated as required. The excavator, which is enclosed by a housing 15, stands on the cover 6 which is fixed to the supports 7, 8 and is rendered gas tight by means of circular flanges 21 on its under surface dipping into tar or the like, contained in troughs 20 round the inner and outer edges of the circular den. The gases which may be removed by means of a fan are thus prevented from escaping; a gas trap is also formed by the material after being thrown from the elevator into a shoot leading to another elevator or conveyer.

Initial cooling may be by liquid or air, while the secondary quench bath may contain one or more salts in solution, particularly sodium tetra-borate or silicate, and/or a natural or synthetic surface-active agent such as palmitate, stearate or oleate of sodium or potassium, a sodium alkyl sulphonate type or an ethylene oxidealkyl phenol condensation product. The overall cooling rate may be such that the rod develops a bainitic structure. The product is used for concrete reinforcement.

Title: Improvements in or relating to stabilised low frequency oscillators
IPC: H03B5/16
Filed: 1957-03-01
Abstract: 806,078. Thermionic discharge tube generating circuits. MARCONI'S WIRELESS TELEGRAPH CO. Ltd. March 1, 1957 [March 6, 1956], No. 6889/57. Class 40 (6). A bridge-stabilized oscillator of the Meacham type, uses two valves V1, V2 as a " longtailed pair " to connect the output of the bridge to the input of the amplifier valve V3. The voltage across R3 is applied to V1 and via the common cathode resistor to the valve V2, and the voltage across LC is applied to V2. The difference between these voltages appears at the anode of V2 and is applied to the grid of the amplifier valve V3. The output of the valve V3 is applied to the input terminal I1 of the bridge, the other input terminal 12 being held at zero potential by capacitor C12. The common cathode resistor is tapped to provide the bias for V1, V2. The oscillator output may be taken from the common cathode resistor RL or from the anode and cathode of VI. The stabilizing element of the bridge may be of the negative temperature coefficient type such as a thermistor. Provision may be made for limiting the high-frequency response of the amplifier.

Abstract: 313,654. Shell-Mex, Ltd., and Lawson, J. March 16, 1928. Addition to 297,764. Plug cocks; wedging or jamming.-In a plug cock 1, according to the parent Specification, the inlet passage 7 of the plug and the axial-thrust balancing-chamber 13 are isolated from the sidebalancing recess or pocket 9, and consequently from inlet presure, during that part of the movement of the plug 1 wherein the said inlet passage 7 is entirely out of register with the supply port 3; the plug is therefore permanently balanced laterally but is only balanced axially in the end positions of rest, thereby facilitating turning. For this purpose the inlet passage 7 communicates with the pocket 9 through a non- return ball valve 12 disposed in a passage 11; this prevents the access of liquid from the passage 10 and pocket 9 to the inlet passage 7 and the escape of liquid during the act of reversal of the cock. The balancing-chamber 13 communicates with the inlet passage 7 through a passage 13<1>, so that the balancing-chamber is not subject to fluid pressure during the act of reversal of the plug and is therefore more easily moved.
