Abstract: 612,543. Inductances and transformers. RENARD, E. May 27, 1946, No. 15977. Convention date, Sept. 25, 1945. [Class 38 (ii)] A variable high-frequency inductance or transformer is provided with a substantially cylindrical hollow former 1 of moulded insulating material constructed so that it can be mounted alternatively within a hole or recess B in a plate A with its longitudinal axis within the plane of the plate, or at right angles to the plane of a single plate or between a pair of parallel plates. The former 1 is screw-threaded internally to receive an adjustable iron dust cover, and may carry a pair of oppositely directed cup-shaped members of the same magnetic material which co-operate to enclose a coil. The inner end of the former is provided with a pair of longitudinal, shouldered slots 6, 61 to engage the rear edge of the recess B when mounted as shown, and the front end is formed with two diametrically opposite thickened portions 4, 4<SP>1</SP> provided with. longitudinal slots 5, 51 respectively to receive resilient tongues C formed on the mounting plate at the entrance to the recess B. The front end of the former is provided with two arcuate flanged portions 2 separated by gaps or recesses to the rear of which the thickened portions 4 are situated. When mounting the former at right angles to a plate, the plate is provided with a circular aperture which is notched to receive the flange portions 2, and the former is secured by a resilient split disc which is sprung between the portions 2 and the face of the plate. The open rear end of the former may be closed by a bifurcated resilient strip which has arcuate lateral projections midway along its limbs to spring behind a pair of inwardly projecting lugs at the rear end of the former. The bifurcated strip may also serve to secure the rear end of the former when mounted between a pair of parallel plates, the rear plate being suitably apertured to allow the end to project therethrough.

Title: Improvements in or relating to molten bath electrolytic-metallurgical apparatus
IPC: C25C7/00
Filed: 1962-04-27
Abstract: <PICT:1006232/C6-C7/1> Electrolytic molten bath apparatus, e.g. for producing pure Zr, comprises a cell 1, an isolating valve 3 (e.g. as described in Specification 930,365), a lock-chamber 4, an injection pipe 9 slidable through a stuffing box at the top of the chamber 4, a perforated basket 6 at the lower end of the injection pipe 9, and a tube 11 round the injection pipe and in which a sheath of heat insulating material, e.g. a gas, can be enclosed, whereby a substance may be introduced in a gaseous state through the injection pipe 9 into the molten bath and the perforated basket 6 may be introduced into the bath without modifying the atmosphere above the bath.  The lock chamber 4 has a pipe and valve (not shown) so that it may be placed in a state of vacuum or controlled atmosphere.  The injection pipe 9 may be heated electrically or by hot fluid flowing through a coaxial tube between it and the tube 11, the tube 11 containing heat insulation. The outer surface of the tube 11 may be degassed as it is lowered into the lock chamber.  A deflector 25 prevents radiant heat and splashings from the bath from reaching the tube 11.  A device 22 cleans the outside of the tube 11 as it is raised.  In preparing pure Zr, the basket 6 is filled with Zr wastes and this and the injector pipe 9 are lowered into the molten bath 2.  ZrCl4 in gaseous form is then passed from a heated chamber through the heat insulated injector pipe 9 and basket 6 to form zirconium sub-chlorides in the bath. When the desired concentration is reached the pipe and basket are withdrawn to the lock chamber, the valve 3 closed, the flange 14 unfastened and the unit 5 replaced by the electrode necessary for electrolysis.

Abstract: 561,871. Crushing or pulverizing machines. HIGHFIELD, J. S., and FAIRLEY, T. Nov. 26, 1942, No. 16815. [Class 59] A crushing or pulverizing machine of the revolving hammer type has an inlet for the material to be treated located about the vertical plane containing the axis of rotation of the hammers so that the hammers strike the material substantially horizontally and the wall of the machine is so shaped that the material so struck impinges on the wall at an acute angle and ricochets in the direction of the discharge outlet of the machine. In the machine shown in Fig. 1, material fed through the opening c is struck by the revolving hammers e and directed against the wall l of the casing in the form of a circular arc struck from a centre below the centre of the rotor a. The rotor carries end plates f on which the hammers e are pivoted. The casing has a removable section d serving for inspection purposes. In the modification shown in Fig. 3, the casing has four plane impact surfaces and the material is discharged into a hopper o and on to a screen p through which the fine material passes on to a conveyer, the coarse material being returned by an elevator to the feeding inlet of the machines. In both types of machine the space between the rotor and impact walls increases in width downwardly and the wall opposite to the impact wall conforms fairly closely to the path of the hammer tips.

Abstract: 1389759 Photo-electric analysis of chemical reactions: measuring rate of change of voltage BECKMAN INSTRUMENTS INC 10 April 1973 [17 April 1972] 17119/73 Headings G1A and G1U In a system for determining the rate of change of a voltage 31, Fig.1, which after an initial settling period is expected to rise linearly, e.g. as in Fig.3A or 3B, the voltage is differentiated 34 and rectified 35, and when the voltage is expected to be rising linearly, the resulting rate signal 37 is measured 40, 45, Fig.2, and displayed 48, means being provided to ensure that the measuring does not start too soon and to ensure that the display is blanked and an over-range light energized, if the rate of change exceeds the range of the system. As described measurement of the rate signal 37, which is expected to be constant, is effected by repeatedly sampling and digitizing 40 the signal over a period of 13 seconds, and averaging the results in an accumulator 45. The measurement commences once a gate 161 produces an output which occurs as soon after a pre-set time delay 78, Fig.1, as the second derivative 65 of the input signal 31 falls below a level pre-set into a comparator 66, this level being a function of the first derivative of the input signal. Once started the measurement cycle continues until a timer 43 indicates its conclusion, and if during this period either the rate of change of the input signal is too high, or the input signal itself is too high or too low, then the display is blanked by a signal from a gate 230. The various threshold parameters are set into the system initially in accordance with the reaction being monitored, and as described the reaction, which takes place in a cell 12, Fig.1, and may involve an enzyme, is monitored by detecting 16 monochromatic light transmitted by the reaction.
