Filed: 1959-03-05
Abstract: 905,432. Transistor oscillators. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. March 1, 1960 [March 5, 1959], No. 7726/59. Class 40 (6). A circuit for generating both sine-wave oscillations and a rectangular waveform accurately in phase therewith comprises a plurality of transistor amplifying stages connected in cascade in a loop to provide positive feed-back, the coupling between one stage and the succeeding stage comprising a series-tuned circuit L1, C7 so that a sine-wave oscillation appears at point H and the coupling between two other stages comprising a diode bridge D1-D4 which limits the input sine-wave signal thereto to provide a square-wave signal which is further sharpened by subsequent stages T6, T7, T8 to provide a rectangular-wave output at D. In Figs. 1 and 2 the output point B of Fig. 1 is connected to the input of Fig. 2 and the output point A of Fig. 2 is likewise connected to the input of Fig. 1. Heavy negative feed-back is provided from the output of emitter-follower stage T2 to the input of T1; negative feed-back is similarly applied from the output of T4 to the input of grounded-base stage T3. This ensures extremely small input and output impedances for the series-tuned circuit and allows it to operate with a high Q. The input and output impedances to the diode bridge are arranged to be low compared to the forward resistances of the diodes. Resistances R23, R24 are large compared to the forward resistances but small compared to the reverse resistances of the diodes. Sinusoidal output is taken from point C connected to the output of emitter-follower T5 supplying the diode bridge; rectangular wave output clamped between - 6 volts and the emitter voltage of T8 is taken from point D. Specification 905,433 is referred to.

Abstract: 569,342. Testing physical qualities. BENGOUGH, G. D., WORMWELL, F., YARDLEY, V. A., and NURSE, T. J. June 8, 1942, No. 7800. [Class. 106 (ii)] [Also in Group III] Apparatus for testing the corrosion resistance and durability of metals, metallic coatings, protective compositions and other finishes comprises a container with the corrosive fluid in which the specimens to be tested are immersed and moved. Suitably prepared metal specimens are mounted in circular holders 1 which can be rotated in the corrosive fluid at any desired speed. The holders 1 are mounted between cover-plates 2 and are attached to the ends of steel spindles which are supported in self-lubricated bearings 10 outside the tank 4. Such holder is rotated about an axis inclined to the vertical, the unit being offset in a rectangular tank 4 containing the corrosive liquid to avoid vortex in the liquid. The specimens are fitted in slots around the periphery of the holder and held by screws so that the prepared face of the specimen flush with the ebonite holder alone faces the fluid. Each specimen is insulated from the others and from the steel spindle. The joints between holder and cover-plate 3 are made water-tight by gaskets. The spindles have ebonite sleeves 8 and ebonite nuts 7 clamp the parts together. The tank is of glass and other parts in contact with the fluid of ebonite, while the bearings for the spindle are external to the level of fluid. The apparatus is arranged in a battery of serial units. The speed of rotation is measured by a stroboscopic disc 11 on top of the motor spindle. An alternative form of specimen is a ring of metal cut from a circular tube. Local turbulence at a desired area may be promoted by providing a small protrusion on the holder, or a baffle may be fitted in the tank. The tank may be placed in a gas-tight chamber when testing the effect of moving gases. For some purposes, a current may be supplied through two of the specimens, or it may be desired to measure the current set up between two specimens. For this purpose, slip rings near the upper end of the ebonite sleeve are connected to the chosen specimens. Specification 283,539, [Class 106 (ii)], is referred to.
