Abstract: 345,162. Centrifugal governors. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE, 12, Hallesches Ufer, Berlin. June 4, 1930, No. 17153. Convention date, June 8, 1929. [Class 57.] In a winch for winding an aerial on aircraft of the kind provided with a centrifugal weight brake adapted to operate for one'direction of rotation only, the brake weights b<1>, b<2> are positively prevented from separating when rotation occurs in the other direction by the engagement of pins d<1>, d<2> mounted on them with the ends of slots e formed in a member c. The shaft x of the winch H drives the member c through gears u, v, and the member c drives the plate a carrying the weights b<1>, b<2> by means of a pin m depending into one of the apertures g<1>, g<2>. When the winch rotates in one direction, the pin m engages a certain point on the wall of an aperture and the pins d<1>, d<2> are in the openings f of the slots e. In consequence the weights are free to swing outwards about their pivots i<1>, i<2> into contact with the braking surface r. When the winch rotates in the opposite direction, the pin m engages a diametrically opposite point on the wall of the aperture, and in this position the pins d<1>, d<2> are within the slots e and the weights are prevented from moving.

Title: Improvements in electrical control systems
IPC: G05D1/02
Filed: 1936-06-20
Abstract: 482,189. Distant - control systems. SPERRY GYROSCOPE CO., Inc. June 20, 1936, No. 17218. Convention date, June 20, 1935. [Class 40 (i)] [Also in Group XXXV] In a remote control or follow-up system, the servomotor is controlled differentially through two balanced valve circuits which are controlled by the primary and secondary members of the system through the intermediary of two condensers or a condenser and a variable resistance or tapped transformer. The Figure shows a system wherein a ship's rudder 28 is controlled from a compass to maintain the ship on a set course. The compass controls a condenser 8, 9 the plate 8 of which is manually adjusted by a knob 5 to determine the course and the plate 9 is operated by the movable element of the compass. The condenser controls the tuning of the input circuit of a rectifier 14 which is coupled to an oscillation generator 10. The output of the rectifier 14 is varied in accordance with the position of the condenser 8, 9 and is applied to the valve 40 of the amplifier unit AU, the radio frequency component of the output being filtered out by choke 16 and condenser 47. A similar generator-rectifier unit 101, 141 is controlled by a condenser 19, 20 operated by the rudder motor 23 and the arrangement is such that normally the rectifier outputs are balanced, but any departure of the condenser 8, 9 from the normal position destroys the balance and the D.C. motor 23 operates the condenser 19, 20 to restore the balance. Instead of the condenser 19, 20 a variable resistance or tapped transformer may be employed. Anti-hunting arrangements of the type employing a derivative of the signal input as described in Specification 473,753 may be employed. In a follow-up system for a gyro compass, the sensitive element controls one plate of a differential condenser, the other two plates of which are mounted on the followup element and control two rectifiers, the inputs of which are derived from a single radiofrequency generator. Specification. 417,995 also is referred to. The Specification as open to inspection under Sect. 91 describes a system employing a repulsion motor instead of the D.C. motor 23. This subject-matter does not appear in the Specification as accepted.
