Title: Improvements in the refining of lead
IPC: C22B13/06
Filed: 1919-05-16
Abstract: 142,398. Harris, H. May 16, 1919. Dry processes of refining lead.-Lead is refined by passing the molten metal in thin streams through a molten reagent, which may be that described in Specification 142,315. The reagent is contained in an iron cylinder b mounted in a pot of lead a in a furnace. The lead to be refined is heated in a pot d and is forced up a pipe e by air pressure applied through a pipe f. Compressed air admitted through a pipe h sprays the lead into a perforated dish c from which it passes through the reagent. The lead after passing through the reagent flows to a pot d' from which it may be passed again through the same or a different reagent for further treatment. By reversing the position of the channel l, the refined lead may be finally led into the pot d and thence discharged to a vessel n.

Title: Improvements in or relating to ultra-high-frequency electro-magnetic coupling devices
IPC: G01R1/26
Filed: 1947-09-19
Abstract: 633,791. Current and voltage measurements. SPERRY GYROSCOPE CO., Inc. Sept. 19, 1947, No. 25572. Convention date, Sept. 20, 1946. [Class 37] [Also in Groups XL (b) and XL (c)] An ultra-high-frequency device, for sampling the field strength within a transmission line such as a waveguide or coaxial line, comprises an aperture in the boundary of the transmission line opening into a section of wave-guide dimensioned below cut-off, and a probe or loop extend. ing into the field space within the waveguide section but not within the boundary of the transmission line. Fig. 1 shows an elongated waveguide section 14 positioned over a slot in the outer conductor of a coaxial line 10. A probe 41, held by insulating beads in an outer-sheath 30, is vertically adjustable by a knob 31 in a carriage 17 which is longitudinally adjustable along the wave-guide section by a knob 18. Fig. 3 shows a section of the device when mounted on a rectangular wave-guide 50. As no energy is propagated through wave-guidesection 14, the field strength varies exponentially with distance from the slot, and, being substantially zero at the open end, there is no current through the carriage 17. If the rate of variation is made small, the effect of irregularities in the carriage 17 is reduced. If the carriage 17 is traversed longitudinally with probe 41 set at a given distance, the field strength as measured by a detector connected to the probe will exhibit the same variations as are present along the transmission line, thus enabling the standing wave ratio to be determined. Also the probe can be positioned to give a desired deflection. Alternatively, the probe can be adjusted for each position of the carriage so as to give the same deflection on the output meter, the relative field strengths then being given by a calibrated scale 42 movable with the probe. This avoids errors due to the non-linearity of the meter.

The motor of a vibrator, e.g. a concrete vibrator, is protected by providing a heatsensitive impedance in the vibrator casing adjacent the motor. This impedance 8 may be a thermistor or a wire resistor wound over the projecting stator windings of the motor. The impedance 8 may be connected as one arm of a resistance bridge 9 the output of which is amplified in a linear amplifier 13 and applied to a phase-sensitive detector 14. The output of the detector is applied to a trigger circuit 16 which changes its state when the detector output voltage increases beyond a value determined by the permissible maximum motor temperature. This change of state results in the switching-off a power transistor (not shown) to de-energize the coil 17 of a contactor controlling the supply to the vibrator motor.
