Abstract: 1334020 Gain control ROBERT BOSCH FERNSEHANLAGEN GmbH 8 Dec 1971 [8 Dec 1970] 56936/71 Headings H4R and H3T A transistor circuit for amplifying an A.C. signal in which the amplification of the circuit varies linearly with the magnitude of a D.C. control voltage applied thereto comprises a first transistor amplifier for amplifying the A.C. signal and a second amplifier, arranged as a D.C. amplifier, which is arranged to modify a control voltage delivered to both amplifiers so as to cause the required linear relationship between the unmodified control voltage and signal amplification to be obtained. The circuit may be used to amplify video signals. The signal amplification circuit comprises a differential amplifier including transistors T3, T2 having a transistor T1 to which the signal to be amplified is applied, connected in their common emitter lead. The D.C. amplifier comprises a similar arrangement of three transistors T1<SP>1</SP>-T3<SP>1</SP> which has in addition direct voltage negative feedback between the collector of transistor T3<SP>1</SP> and its base. The control voltage is fed via line 5 to a point common to the base of a transistor in each of the two circuits and the output is taken on line 11. Because of the feedback loop, a linear relationship is established between the control voltage and the current through transistor T3<SP>1</SP>. Hence a linear relationship also exists between the control voltage and the current through transistor T2 thereby yielding a linear characteristic. By connecting together the outputs of the two amplifiers it can be arranged that the mean direct voltage value at point 11 does not vary during the amplification control. It is stated that for a satisfactory operation it is necessary for the currents through transistors T1 and T1<SP>1</SP> to be substantially equal. This is achieved by supplying a suitable constant D.C. potential to the base 14 of transistor T1<SP>1</SP>.

Abstract: 1335992 HVDC power transmission BROWN BOVERI & CO Ltd 9 Dec 1970 [11 Dec 1969] 58524/70 Heading H2F In a short HVDC link connecting two A.C. networks, he transmitted power is adjusted by simultaneous conduction control of current and voltage in the link, said control being arranged to change the reactance of the inverter so as to maintain constant the voltage or power factor of the output A.C. network. The inverter is loaded by three-phase capacitors or filters for supply of reactive power. Simultaneous control of D.C. voltage and current in the inverter will then permit adjustment of transmitted power without variation of power factor. Alternatively, the power may be adjusted by variation of current (or voltage) of one converter whilst the network power factor is corrected by variation of the voltage (or current) of the other converter. A phase shifter and tapped transformer may be included on the A.C. side of the rectifier so as to maintain constant the voltage or power factor on the input A.C. side.

Abstract: 601,964. Gyroscopic apparatus. SPERRY GYROSCOPE CO., Inc. Sept. 28, 1944, No. 18587. Convention date, March 1, 1943. [Class 97 (iii)] In an erecting device, particularly for direction-indicating gyroscopes the erecting torque is established by an air jet discharged from the closed casing 27 of the rotor, the discharge channel 46, as shown in Fig. 4, having a rear opening 48 through which additional air is drawn to augment that from the rotor case. The channel extends radially with respect to the axis of the inner gimbal ring 28 and the jet is directed on to a central deflector 51 on a plate 50 carried by the outer vertically-pivoted gimbal ring 22 or by the pivoted arm 53 of the usual caging device mounted on the ring. The rotor is preferably air-driven and, in addition to the channel, escape holes 39 may be provided in an end plate of the rotor case. When an electrically-driven rotor is used an air pump provides pressure for the controlling jet.

Abstract: 695,136. Spinning yarns. MEIMBERG, J. Nov. 20. 1950 [Nov. 23, 1949], No. 28287/50. Class 120(ii) [Also in Group XXV] Fibrous material is spun by collecting fibres from a source of supply by a collecting device mounted on a rotating carrier and carrying out, in addition to the rotation imparted by the carrier, an individual motion relative to the carrier; the fibres are then supplied by the collecting device in a direction perpendicular to the spun yarn to a spinning position where they are formed into a spun yarn to which rotation is imparted by the rotation of the carrier so that the spun yarn is continously withdrawn at a speed equal to that of the collecting device relative to the carrier. The apparatus shown, Fig. 1, comprises a disc 9 rotating about the axis of the spun yarn and carrying drums 12, 14, 15 geared together and rotating relative to disc 9 in the directions shown. Disc 9 rotates in the same direction as drums 14,15, and a needle band 24 passing around drums 12, 14, 15 and guide drums 20, 21 travels slowly forward relative to disc 9 so that fibres, removed by band 24 from a source of supply 26, are fed to the spinning point at the centre of the disc where, by virtue of the rotation of the disc, they are twisted to form a yarn which is removed through a stationary guide tube 27 and can be forwarded for continuous processing or supplied directly to a knitting machine or the like. A covered yarn may be produced by making the shaft of drum 12 hollow for the supply to the spinning point of a yarn to be covered. Two or more discs as shown rotating in the same direction, may be mounted so as to precess about a common axis and receive fibres from a plurality of supply devices arranged adjacent their path of rotation, the spun yarns withdrawn from the several discs being thereby doubled together on passing through a guide located on the common axis. In an alternative apparatus, Fig. 3, the disc 28 carries a rubber-covered drum 30 and a slotted drum 29 through which project the pins 32 of an eccentrically mounted drum 31; these pins withdraw fibres from a supply, as disc 28 rotates, convey them to the point of contact with drum 30, and release them at the central spinning position.
