Title: Improvements relating to filling and venting devices for electric accumulators
IPC: H01M50/618
Filed: 1944-08-10
Abstract: 574,637. Galvanic batteries. CHLORIDE ELECTRICAL STORAGE CO., Ltd. (Woodbridge, J. L.). Aug. 10, 1944, No. 15273. [Class 53] The filling opening of an accumulator is provided with means for indicating when the correct amount of electrolyte bas been introduced into the accumulator and for allowing air and gas trapped beneath the cover to escape gradually through the filling opening. As shown in Fig. 1 the filling opening comprises a tube 12 which extends downwardly to the level of the electrolyte which rises in the tube when the correct amount has been introduced. Disposed within the tube is a bridge piece 15 formed with a well 18 communicating through ducts 21 with the space 20 beneath the cover of the accumulator. A small opening 19 may be formed in the bottom of the well. When electrolyte is poured into the accumulator the well becomes filled and closes the ducts 21. After the filling operation the electrolyte in the well drains through the opening 19 and gas can then escape through the ducts and tube 12. If the opening 19 is not provided the gas bubbles through the liquid in the well. The upper end of the tube 12 is screw threaded for the reception of a gas vent. Fig 7. shows a modification in which the bridge piece 15 is moulded separately from the tube 12 and is provided with projections 23 which drop into slots formed in the lower end of the tube 12 where they may be cemented in position. The ducts 21 are drilled through the member 15 after it has been made.

Title: Improvements in and relating to radio frequency testing apparatus
IPC: G01R27/26
Filed: 1947-06-10
Abstract: 642,735. Impedance measurements. BRITISH THOMSON-HOUSTON CO., Ltd. June 10, 1947, No. 15277. Convention date, June 10, 1946. [Class 37] A bridge, for the measurement of impedance at radio frequency, comprises four substantially equal arms 1 ... 4 fed with R.F. oscillations from 5 and having a rectifier instrument 8, 9, 10 in the opposite diagonal, a variable calibrated condenser 17 being connected in series with the impedance to be measured across arm 4. Preferably the impedance of the bridge together with resistance 7 matches the impedance of the line 6. To measure the radio-frequency resistance (R) of an inductance 21, it is connected in series with capacity 17 across resistance 4 ; resistance 4 is short-circuited and the meter adjusted to full deflection (marked zero on the scale) ; contact 18 is opened and condenser 17 adjusted to give the maximum deflection (or minimum deflection from zero), at which point the capacitative reactance (C) is equal and opposite to the inductive reactance, and the meter registers the R.F. resistance of the inductance 21. The power factor of the coil may be calculated from the formula 2#C.fR. To measure the resistance and capacity of a condenser 23. a coil of suitable inductive reactance is connected between terminals 14, 15, and condenser 17 is adjusted (to C 1 ) as before to give a minimum reading (R 1 ) on the meter, thus measuring the R.F. resistance of the coil, the capacitative reactance of the condenser 17 being read on its calibrated dial ; the unknown capacity 23 is then connected across condenser 17 which is again adjusted to give minimum reading (R 2 ) of the meter 9, the difference between the two readings (C 2 -C 1 ) of the calibrated condenser 17 being the value of the capacity 23 ; and the R.F. resistance may be calculated from the readings of the meter and the values of condensers 17, 23, being equal. to C 1 (R 2 -R 1 /(C 1 -C 2 ). The power factor is 2#C 1 (R 2 -R 1 /(C 1 -C 2 )<SP>2</SP>. The Q-value may be computed from the reactive (capacitance reactance) and the resistance (R) using the formula ¢#C.fR. A scale is provided below the capacitance scale of the condenser marked in units of a constant=¢#C, where C is the adjacent correlated value on the capacitance scale to enable computation of the Q-value.

Abstract: 621,868. Direct connections between conductors. BRITISH THOMSON-HOUSTON CO., Ltd. May 22, 1946, No. 15520. Convention date, May 25, 1945. [Class 38 (i)] [Also in Groups XXII and XXXV] The resistance coil 1 of a sheath-type heater is secured to a terminal 3 by inserting a reduced terminal-portion 7 into the first few turns 9, 10 of the coil, the turns 9 being fused on the portion 7 and the turns 10 being maintained free. By reducing the terminal at the portion 7, the high resistance provides the necessary welding temperature while the turns 10 are cooled, to prevent them fusing, by the mass of the electrode jaws 16, 17. To prevent oxidation, an inert atmosphere, preferably hydrogen, is provided from a pipe 18. The time of welding is controlled by a relay of the type wherein the delay is determined by the time required for a capacitor to lose some of its charge as described in Specification 496,641, [Group XL].
