Abstract: 784,540. Artificial teeth. MENEGAZZO, R. April 5, 1955 [April 10, 1954; Feb. 22, 1955], No. 10003/55. Class 81 (2). A multi-hinge connection for upper and lower denture sets comprises two pairs of arms, the arms of each pair being hinged together and urged apart by a spring device, each of said arms being connected to one side of each denture set by a rotatable member mounted within the corresponding denture set to permit universal movement between the arms and the denture sets. The arms 2 are mounted on a hinge pivot 1, so that the facing surfaces of the arms 2 form between them a chamber (not shown) surrounding the hinge pivot 1. A spring is coiled within the chamber with one end anchored to one arm and the other end to a part of the hinge pivot which is square in crosssection, so that the arms are urged apart in a vertical plane. The free end of each arm 2 is bent at right-angles to form a horizontal pin 4 having a head 5. The pins 4 project into shells 6 which have a constricted mouth 7 and are embedded in the side of the dentures A, B. In an alternative construction, one or each arm 2, Fig. 4, is formed in two parts hinged together about a pivot 20, 21 and the headed pins 4 are hinged to the free ends of the arms 2 by a vertical or inclined pivot 22, 23. An eyelet 34, Fig. 5, to which a disc (not shown) is hinged may be provided at the free end of one or both arms instead of a headed pin 4. The disc is disposed for rotation within a semi-cylindrical shell embedded in the denture. In other constructions (not shown) vertical headed pins 4, for rotation within a shell embedded in the denture, are secured to the arms 2 by a slidable dovetail joint or by a disc mounted for eccentric rotation upon the arm. One arm 2 of each pair may be pivoted on a pin 1<SP>1</SP> carried by a disc 31, Fig. 5, which is itself pivoted to the other arm 2 and forms with the other arm 2 the chamber containing the spring.

Filed: 1918-06-21
Abstract: 126,199. British Thomson - Houston Co., (General Electric Co.). June 21, 1918. Systems depending on the use of two or more machines.-In alternating-current transmission systems, a predetermined phase relationship is maintained between the current and the voltage supplied to a synchronous dynamo-electric machine despite load variation, by means of a motoroperated rheostat in the exciting-circuit of the machine. The motor 11 of the rheostat 10 is controlled by a relay 16, which makes contact with either of two contacts 19, 20 to complete the circuit through one or other of the field coils 13, 14 of the motor. On the spindle of the relay is fixed a voltage coil 21, which is acted on by a current coil 23. A voltage coil 26 acting on an armature 25 acts in the same sense as the coils 21, 23. Opposed to these two forces are a spring 29, and the attraction on an armature 27 of two coils carrying the exciting-current for the synchronous motor 1 to be controlled. When the phase relationship is normal, the relay contact 18 is between the contacts 19, 20 as shown, but on any variation the contact moves to correspond and causes an adjustment of the resistance 10.

Abstract: 559,243. Correspondence control. SQUARE, D CO. July 30, 1942, No. 10657. Convention date, Feb. 5, 1941. [Class 40 (i)] [Also in Group XL] A communication system for aircraft comprises a transmitter controlled in frequency dependent on the height of the craft and modulating means for the transmitter so arranged that the modulation frequency is dependent on the direction of flight. The Figure shows the transmitter T and receiver R mounted in each of the craft. The frequency of the transmitter is controlled by the altitude as by an evacuated diaphragm 13 controlling the tuning condenser 12. In addition the transmission is modulated in accordance with the azimuthal direction of the craft by a variable frequency. The modulator includes a triangular shaped inductor 35 adapted to have its inductance varied by a movable iron mass 36 pivotally mounted and controlled by magnets 41. To avoid 180 degrees ambiguity a further modulation of say 3,000 cycles is imposed from a coil 45 subtending half of the azimuth circle through relay 46 and modulating disc 47 and a distinct characteristic may be imposed by a similar disc 17. The receiver is tuned similarly to the transmitter in accordance with altitude and its frequency is in addition varied to cover a band of frequencies corresponding to plus and minus 1,000 feet by a motor-driven condenser 15. The altitude of an adjacent craft is shown on an indicator comprising a pointer 28 driven by the motor 23 and illuminated by a lamp 16 when the frequency of the transmitter of the adjacent craft equals that to which the receiver is tuned. The course of the adjacent craft is indicated on a frequency meter 52 having two pointers 53, 54 only one of which is illuminated under the control of relay 59 to avoid the 180 degrees ambiguity. A signal strength indicator 60 is used as a distance indicator a setting mark 63 being provided to show whether or not the craft are approaching one another. A blanking disc 31 is provided to render the transmitter inoperative while the receiver is operating. Modulation by the discs S1, S2, S3 may be effected by short circuiting part of the grid leak resistance of the oscillator. Specification 559,259 is referred to.

Abstract: 106,622. Chadburn, W., and Chadburn, W. R. Jan. 3, 1916. Periodic - counter speed indicators.-The rotation of the uniformly-rotating timeshaft 20 is derived from the shaft 3 of which the speed is to be determined, by rotation through a friction or spring coupling 11 under the control of centrifugal governors 9, 10 at the beginning and end of the train. The shaft 14 driven through the coupling 11 rotates the governor 9 direct, and drives a transverse shaft 33 through bevel-gears 30, 32; a worm on this shaft rotates a wheel 35, which in turn drives a worm 37 on a shaft 38, from which the time-keeping shaft 20 is driven by a screw gear. The second governor 10 is driven by worm gearing 42 from the shaft 38. Adjustable brake blocks are provided for the governor disks 25, and, to facilitate starting of the slip coupling 11, a spring wheel 45 is provided having an external milled head 48 and blocks 49 for engagement with the disk 25. A pointer is driven from the shaft 20, which gives one rotation per minute or other unit of time. The Provisional Specification outlines the general nature of the speed-measuring mechanism.
