Title: Improvements in the manufacture of potassium pyroantimonate
IPC: C01G30/02
Filed: 1956-03-29
Abstract: Hydrogen peroxide is added with stirring to a suspension of antimony trioxide in aqueous potassium hydroxide at an initial temperature not exceeding 35 DEG  C. at such a rate that the mixture does not rise above 85 DEG  C., whereby potassium pyroantimonate is formed.  The potassium hydroxide is present in such amount in excess of that required by the formula, that the solubility of the pyroantimonate is depressed and it settles out in not more than 12 hours but not so rapidly as to coat the trioxide and stifle the reaction.  This amount increases as the concentration of trioxide in the suspension decreases.  Using 190 g. of the trioxide in 750 cc. of water a 25-100 per cent excess of potassium hydroxide may be used.  The mixture may be heated up to 95 DEG  C. after adding the hydroxide.  In the example, a second batch of potassium pyroantimonate was obtained by adding further quantities of the reactants to the mother liquor from the first batch.

Title: Improvements in or relating to electric selective signal-responsive devices
IPC: H02J13/00
Filed: 1939-03-31
Abstract: 528,790. Electric signalling systems. STANDARD TELEPHONES & CABLES, Ltd., and BOWSHER, A. H. March 31, 1939, No. 10112. [Class 40 (i)] Selector mechanism responsive solely to a pair of impulses of predetermined spacing comprises a carrier which executes a cycle of movement, e.g. one revolution, on receipt of the first impulse, an actuating member pivoted on the carrier and held inoperative by a spring until deflected by the second impulse and a variably positioned displaceable member in the path of movement of the actuating member engaged by the actuating member if the interval between the impulses corresponds with the positioning of the displaceable member. In the circuit an arrangement shown in Fig. 4, D.C. impulses over power line LN operate magnet M over transformer Tr so that the magnet does not respond to power A.C. In response to the first impulses, the magnet closes contact C1 to start a motor which drives the selector Sc the motor circuit being maintained over off-normal contacts ONS for one revolution. The selector under the control of the second impulse closes a main switch MC to switch in the load LD. The selector, Figs. 1 and 2, comprises a shaft SP driven by the motor and carrying loosely an oval switch plate P1 controlling a bell-crank BC operating the main switch MC, the plate being normally prevented from rotating by a latch bar LB engaging one or other of the spring controlled levers L1, L2 which project through spaces between fixed projections J. The shaft SP when rotated counterclockwise winds up a spring MS which has a slipping engagement with the pins on the plate P1 to prevent over-winding. A gear wheel G fixed to the shaft engages a planet pinion W mounted on a disc D1 loose on the shaft and urged in the clockwise direction by spring LS so that an actuating member H on the planet lies substantially in the position shown. As explained above, the motor is started by the first impulse and the shaft rotates for one revolution. The second impulse causes magnet M to apply a brake B to disc D1 whereupon the planet W rotates clockwise and member H, passing between the pair of projections J opposite to it at the time of the impulse, swings round in the counter-clockwise direction and clicks over the 'remaining projection J. If a lever L1 or L2 is located in the gap between the projections J entered by the member H, the lever is released from the latch bar LB and the oval cam P1 is rotated by spring MS to operate the bell-crank BC. The levers L1, L2 control on and off switching respectively. In a modification, Figs. 5 to 7 (not shown), in which the projections J and sun and planet gear are dispensed with, the actuating member H is carried by a plate rotating with the spindle and is released by a spring controlled member held until the arrival of the second impulse whereupon it flies around and engages the member H to swing it into engagement with one of the levers if the impulse arrives at the predetermined time interval. Specification 495,057 is referred to.

Abstract: 1,201,845. Vacuum vapour coating apparatus. NUCLEAR MATERIALS & EQUIPMENT CORP. March 4, 1968, No. 10395/68. Heading C7F. During a process for vacuum vapour-deposition on a particulate substrate, the attitude of the particles relative to the source of vapour is repeatedly changed to ensure uniform coating, and the particles are repeatedly injected and reinjected into the vapour substantially at random at the start of each injection to change the attitude of the particles relative to the vapour. The particles, of u, its carbide or oxide, Al or Al2O3, are introduced into the apparatus on surface 91 and the chamber is then evacuated. A beam of electrons from cathode 35 Fig.1 (not shown) impinges on target material 33, of Ta, W, Mo, Zr, Al, or an oxide of any of these, so that vapour of the coating material is produced adjacent surface 91. The conveyor 29 may be moved vertically and also rotated about a vertical axis, the movement from a given position being slower than the return thereto so that particles on surface 91 are separated momentarily therefrom by virtue of their own inertia, and this means is actuated throughout the coating process. Particles are coated with material 33 whilst moving down surface 91, and then fall through hole 93 on to surface 89, and are moved by the slope of 89 and centrifugal action to track 99 from which ascending helical tracks 90, 92, 94, 96, lead at regular intervals so that by virtue of the rotation of the conveyer the particles ascend the helical tracks to return to surface 91 at its upper edge, and proceed again to hole 93 for recycle.

Title: Circuit arrangements for obtaining a control or measuring voltage

Filed: 1941-08-18
Abstract: 581,887. Automatic volume control. KOLB, O. K. (Electrical Fono-Films Co. Aktieselskab). Aug. 18, 1941, No. 10474. [Class 40 (v)] [Also in Group XXXVI] An arrangement for obtaining a control or measuring voltage logarithmically related to an applied signal voltage comprises a dry rectifier, which operates with a limited logarithmic range, connected in series and matched with one or more thermionic valves which correct and extend the logarithmic range of the device. The transformed voltage may be used for automatic gain control or other purposes. In Fig. 4, a portion of the signal voltage is fed across terminals A], A2 through transformer T1 to the control grid of correction valve K. The output is taken from across the anode load Ra and fed to two dry rectifiers D1, D2 connected in opposition through condenser C and resistance Rd and then to an amplifying valve U. Resistance Ra is adjusted to match valve K and the rectifiers so that the valve K does not affect (other than amplifying) voltages within the strictly logarithmic range of the rectifier. A high ohmic resistance Rg is included in the grid circuit of valve K to allow the flow nf grid current when the control grid is positively biassed, thus limiting the rise in anode current as the potential applied in the grid circuit rises. This has the effect, when the value of resistance Rg is correctly chosen, of changing gradually the characteristics of the valve K from a linear to a longarithmic relationship as those of the rectifier change from logarithmic to linear. Multi-grid valves may be used to increase this degree of correction by (1) using a pentode which also has its screen grid connected through a predetermined resistance Rg4 (Fig. 6, not shown), to the H.T. supply, or (2) using a heptode, Fig. 7, in which control grid G1 is connected in push-pull with G3 and grids G2 and G4 are connected to fixed potentials.
