Title: Improvements in and relating to regulators for dynamo electric machines
IPC: H02J7/22
Filed: 1926-03-30
Abstract: 270,065. Glaser, W. H., and Vandervell & Co., Ltd., C. A. March 30, 1926. Regulating, automatic.-The vibrating contacts a for shorting a resistance b in circuit with the field c of a, dynamo d, are normally under the control of shunt and series coils e, f. The regulator thus controls the voltage to be suitable for completely charging the battery k. As this voltage would be too high for the lamps j, an additional shunt coil h on the regulator is arranged to be switched in by a switch i when it is desired to use the lamps. This additional coil causes the regulator to regulate the dynamo to a lower voltage. The series coil f may be shunted by a resistance g as described in Specification 248,167.

Abstract: 250,933. Soc. Industrielle des ProcÚdÚs W. A. Loth. April 15, 1925, [Convention date]. Leader gear for assisting navigation; wiredwireless systems. - Guide-conductors are fed simultaneously or successively with alternating currents of different frequencies, from a single generator, such as a thermionic valve, thus permitting the simultaneous use of different receivers variously located on the vessel or craft under guidance. As shown in Fig. 1, a backcoupled valve 1 is associated with a choice of tuning-condensers 4, which are brought into circuit at will by means of a rotating switch 5. The generated currents are fed either to a submarine cable 9, or to aerial lines 11 or 12, the return circuit being closed through the armouring 10 of the cable, through an insulated wire 13, or through ground, or sonorous or unsonorous frequencies may be transmitted as described in Specification 219,726. Alternatively the oscillation-generator may be a Poulsen arc. Several generators may be employed to feed currents of different frequency simultaneously to the guidelines, or successive impulses of different frequencies may be fed from the same source by means of the switch 5 and key 2. The intensity of the magnetic-field radiation may be controlled by means of a rheostat 15, 16 in a definite timecycle, so that the incoming navigator can gauge his distance from the guide-lines by the relative duration of the sending and spacing intervals of the received signals. Fig. 4 shows various endconfigurations of the guide-lines or cables 9 when used for guiding a ship or aeroplane to a definite spot. Fig. 3 shows an arrangement in which means for telegraphic or telephonic communication are incorporated with the cable leader gear. Carrier currents from the generator 1 on the lefthand side of the Figure are modulated by a microphone 22, whilst incoming signals are received by telephones 20 when the switch 7 is in the position 7'. When the switch is in position 7" a telegraphic recorder 23 and sending key 25 are placed in circuit with the cable 9. The station on the right-hand side of the Figure is similarly equipped except that amplifiers 26, 27 are mounted in the telephonic and telegraphic receiving circuits respectively.

Title: Improvements in shock absorbers
IPC: F16F9/14
Filed: 1931-03-30
Abstract: 367,608. Hydraulic shock-absorbers. McNAB, A., 886, Main Street, Bridgeport, Connecticut, U.S.A. March 30, 1931, No. 9631. Convention date, March 31, 1930. [Class 108 (iii).] In hydraulic shock-absorbers for vehicles a piston is moved axially in a cylinder by rotation of a spindle lying in the axis of the cylinder and on which the piston is mounted. The cylindrical casing 10 is secured to the frame of a vehicle, and an operating lever 55 connected to the axle oscillates a spindle 30 formed with a number of splines 36 engaging the piston 40 which can thus move axially but is compelled to rotate with the spindle. The periphery of the piston is formed with several helical projections 41 which engage similar recesses in a liner 15 secured against rotation in the cylinder 10. Rotation of the spindle 30 thus screws the piston into and out of the cylinder. One-way valves 71 ensure relatively free movement in one direction, while movement in the other direction is restricted by flow of liquid through passages 85, 86 controlled by an adjustable valve 90. Shallow grooves 80 in the spindle of slightly greater length than the thickness of the piston allow free movement at or near the central position. A cover 51 forms a liquid reservoir from which liquid may be supplied through one-way valves 100 to the working chambers, while air may escape to the reservoir through a small opening 105 at the upper end.
