Abstract: 1,068,606. Shovel excavators. LENINGRADSKY FILIAL VSESOJUZNOGO NAUCHNOISSLEDOVATEJSKOGO INSTITUTA STROITELJNODOROZHNYKH MASHIN. May 27, 1964, No. 21881/64. Heading E1F. [Also in Divisions G3 and H2] The boom-slewing mechanism of a rotarybucket excavator is driven by an electric motor which is supplied by a generator having its field winding excited by a magnetic amplifier. Computers for controlling the magnetic amplifier are used to determine the desired slewing- speed and the extreme positions of slew, as well as providing signals for stopping and reversing the motor at said limiting positions. As shown, tachometer generator 10 is driven by motor 11 and its field winding is excited by rotary transformer 18 in accordance with the cosine of the angle of slew. The output of the tachometer generator is compared with a voltage representing the initial slewing-speed and the error voltage is applied through amplifier 22 to pilot motor 23 for adjusting transformer 24. This transformer is associated with ring demodulator 17 and magnetic amplifier 14 for controlling the excitation of generator 12. The maximum slewing-angles in either direction are calculated by means of a formula connecting various factors, these factors being respectively dependent upon the width of the working-face in relation to a fixed line of advance of the excavator, the length of the boom, the angular inclination of the material being excavated, the angle of elevation of the boom, and the eccentricity of rotation of the boom with regard to a fixed axis. When the actual angle of slew reaches the computed valve, a relay responds to stop the motor, the excavator then being moved ahead automatically, and the boom being swung in the reverse direction.

Regions 2-4 act similar to an impatt diode when the junction between regions 3 and 4 is reverse biased by a bias 6. With a forward bias 7 between the junction between regions 2 and 5 an r.f. signal at 8 will result in current modulated at this frequency being injected into the region 3. For operation as an amplifier the output loading G1 - jS must neutralize any negative conductance -G generated by the Impatt region so that oscillation does not occur. For operation as an oscillator the load conductance G-jS has to be equal to G and the frequency of oscillation can be injection locked to the applied signal. The n<SP>+</SP>-p<SP>+</SP>-p-n<SP>+</SP> device is made of Si and the p<SP>+</SP>-n<SP>+</SP>-n-p<SP>+</SP> device is made of Si or GaAs.

Abstract: 1,056.983. Mixing liquids in proportions. SYMINGTON WAYNE CORPORATION. May 25, 1965 [June 5, 1964], No. 22243/65. Heading B1C. [Also in Division F2]. Gearing for apparatus for dispensing selected blends of two liquids such as different grades of petrol comprises identical cone gears 54, 55 disposed in parallel but inverted relation with the steps aligned and meshable by gears 50, 51 which are simultaneously shiftable axially by common control means to register with selected steps of the cones, the control means itself being adjustable to shift the gear 50 axially relative to the gear 51. As shown the gears 50, 51 constantly mesh gears 46, 47 on shafts 44, 45 driven by meters 7, 15 through which the two liquids flow. The cone gears 54, 55 drive a subtractive differential 42 controlling the position of a valve 18, 19 which controls the flows of both liquids. The arrangement is such that if the flows of the liquids through the meters 7, 15 correspond to the ratios of the gears the valve setting remains unaltered, departure of the flows from the desired blend causes movement of the valve to restrict the flow of the liquid which is in excess of its desired proportion. As shown the cone gears each have seven steps, the smallest step having eight teeth and each succeeding step having eight teeth more than the preceding step, the arrangement providing, when the gears 50, 51 are aligned nine positions of adjustment, one position being beyond each end of the gears, providing for blends of liquid between 0 and 100% of one constituent in equal steps. The gear 50 can be adjusted to be one, two or three steps above the level of the gear 51, such adjustment reducing the number of blends obtainable to eight, seven or six. By changing the member 87 the gear 50 can be adjusted further above the gear 51, reducing the number of blends obtainable still further. In a modification the cone gears are driven by the liquid meters, and the gears 46, 47 drive the planetary gearing for adjusting the valve 18, 19.
