In addition, the motors have voltage-regulators 10, i.e. thryistors 10a, 10b inserted in only one of their phase inputs, actuated by pulse generators 11, and control units 12, 13. Contacting devices 19 are arranged so that they operate only in travel along curves and so that only the outside-curve wheel contacting device is in operation. The motor housings of motors 7a, 7b, 7e and 7f have strain gauges 15a, 15b which measure the torque M provided at each corresponding wheel, which is then compared to the torque M* provided at the outside-curve wheel via contacting device 19. Control units 12, 13 and thyristors 10a, 10b then adjust the measured torque M of each wheel till it is equal to the torque M* provided at the outside-curve wheel. In a second embodiment (Fig. 2, not shown), the wheels of each axle of a four-wheeled vehicle are driven through differential gear-boxes (20) from asynchronous motors (21), (22). A D.C. voltage source (8) and current converter (9) are employed, but only front motor (22) has a voltage regulator (10) in one of its inputs. A tachogenerator (24) is utilized to measure the speed of rear motor (21). Potentiometers (25a), (25b) and voltage source (25c) provide a signal proportional to the radius of the curve and this signal and the tacho signal are combined in a function generator (23). Control units (12), pulse generator (11), and regulator (10) then adjust the speed of front motor (22) to the correct value for negotiating the curve.

Abstract: 1,152,902. Fluid-pressure servomotor systems. K.A. OVERTVEIT. June 3, 1966 [June 3, 1965], No.23692/65. Heading G3P. A servomotor 53 controls a ship's rudder and is itself controlled by a rotary valve having a first part 16 connected to an input shaft 8 and a second part 17 connected by shaft 10 to the rudder so that the latter can provide a feedback to the valve. As shown, the outlet of a pump 69 is connected by valve passages 26-36, Fig. 3a, to the left-hand side of servopiston 66, the right-hand side of the latter being connected to the pump inlet via valve passages 39-51, Fig. 3b. The servopiston is thus moved until rotation of shaft 10 by the rudder causes disconnection of passages 30a and 31a, 30b and 31b, 46a and 47a and 46b and 47b, the latter passages optionally having a tapering form to provide gradual build-up and stoppage of flow therethrough. When the valve is moved in an opposite direction, the connections to the servomotor are reversed. The shaft 8 is connected to an electric repeater motor (6, Fig. 1, not shown) which receives signals via cable (5) from a transmitter (109) operated by the steering wheel (85) or from a transmitter (2) operated by a gyro compass (1), a selector switch (4) being provided to determine which of the transmitters is effective. Indicators (83, 86) and repeater compass 110 are fitted on the steering column. The transmitters and the repeater motor may give step-by-step movement of the valve part 16. The parts 16, 17 are hydraulically balanced both radially and axially and each part is supported at its opposite ends in ball or roller bearings. In a modification, not shown, the inner and outer parts (316, 317) have interfitting radial vanes the spaces between which are inter-connected and fitted with liquid to provide a damping action. Pressurized liquid can be supplied to the spaces to position the inner part relative to the outer part.

Abstract: 1,074,420. Semi-conductor devices. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 31, 1966 [June 30, 1965], No. 24244/66. Heading H1K. An insulated-gate field-effect transistor is produced in a semi-conductor wafer by diffusing-in the source and drain regions, forming an insulating layer over the channel region, forming a thin layer of an active metal (silver, gold, molybdenum or, preferably, aluminium) on the insulating layer over the channel region, and heating the wafer so that the operating characteristics of the transistor are altered. It is believed that the active metal reacts with water present in the insulating layer (which is preferably of silicon dioxide formed by a "dry-wetdry " oxidation process on a silicon wafer) to release free hydrogen which eliminates surface traps in the wafer and thereby increases the transconductance of the transistor. A plurality of transistors may be formed in a single wafer and their characteristics subjected to different degrees of adjustment. A preliminary cleaning process includes forming and removing an oxide layer.
