Abstract: 1,129,420. Automatic speed and power control. ROBERT BOSCH, G.m.b.H. July 18, 1967 [July 20, 1966], No.32961/67. Heading G3R. [Also in Division H2j An emergency current installation comprises an engine driving a three-phase generator whose power is measured by a wattmeter providing signals to an engine controller for counteracting changes of speed. In addition, signals representing deviations from a nominal frequency are passed through an integrating amplifier to be added to the wattmeter signals. The generator voltage Ul is supplied to a frequency selective amplifier 29 through a network 41-44 which effects a phase shift of 90 degrees, this amplifier being set to produce no phase-shift at the nominal frequency of the generator, and to reduce or increase the phaseshift if the actual frequency is too low or too high. The output voltage U2 of the amplifier 29 is supplied to a phase reversing stage 32 having output voltage U3, the voltages U1, U2, U3, being fed to a phasesensitive rectifier 33 providing the regulating voltage UB when deviations from the nominal frequency occur. In the amplifier 29, transistor 47 serves as a driving stage for transistors 46, 48, operating in push-pull. A frequency-responsive negative feedback network comprises a double-T network 65-75 in which resistor 67 compensates for temperature variations. Fine tuning is provided by resistors 69 and 41. If the speed of the generator tends to decrease, for example, the voltage across capacitors 38, 39, are respectively increased and decreases so that the summation of the voltages on resistors 36, 37 results in an output voltage for increasing the speed of the engine, and the frequency resumes the nominal value.

Abstract: 467,797. Electrolytic cells. KODAK, Ltd. Dec. 3, 1936, No. 33164. Convention date, Dec. 17, 1935. [Class 41] In a cell for the electrodeposition of metals the electrode supports 20, 21 are surrounded by shields 24 of rubber or other flexible material to minimize deposition at these points and thereby to prevent shortcircuiting. Agitation of the electrolyte by the rotary arms 14 induces flexure of the shields whereby any deposit thereon is broken up. The shields 24, when bell-shaped or skirted as shown, retain a body of comparatively stagnant electrolyte depleted of metal whereby deposition is further diminished. In a modification the side edges of the electrodes and the supporting feet are mounted between pairs of flexible strips. The invention is particularly applicable to the deposition of silver from thiosulphate solutions.

Abstract: 967,634. Radiation detection systems. ELTRO G.m.b.H. Sept. 29, 1960 [Sept. 29, 1959], No. 33424/60. Heading G1A. The intensity of a point radiation source is measured by forming an image of the source on a radiation detector and imparting cyclic relative motion between the detector and the image focal plane. Radiation from a distant point source is focused by mirrors 1 and 2 on to a detector 3. The mirror 2 is cyclicly flexed between concave and convex form by mechanical, electromagnetic or electrostatic means so that the image is alternately in or out of focus on the detector. The output due to the point source consequently fluctuates cyclicly whereas the output due to background radiation does not. In modifications, Figs 1 and 2 (not shown), mirror 2 is rigid and either it or the detector is moved cyclicly along the axis of mirror 1.
