Filed: 1933-12-06
Abstract: 429,284. Variable speed gearing. COLUMBIA AXLE CO., 850, E. 72nd Street, Cleveland, Ohio, U.S.A. Dec. 6, 1933, No. 34309. Convention date, Dec. 6, 1932. [Class 80 (ii)] [See also Group XXXI] An epicyclic two-speed gear has its annulus 24 connected to the planet carrier 30 of the rear axle differential 33, 35 of a motor vehicle, and its planet carrier 20 to the crown gear 13, while its sun gear 25 is adapted to be connected, either to the carrier 20 to give a solid drive, or to a fixed part of the housing to give an overdrive, a synchronizing friction clutch or brake 56, Fig. 3, being temporarily interposed during gear changing between the sun gear and the member to which it is to be connected. In the form shown, the sun wheel 25 may be connected by a clutch 40 either to a sleeve 19 projecting from the carrier 20 or to fixed teeth 47. The clutch 40 is shifted by a pair of pins 50, Fig. 3, carried in a yoke 76, Fig. 1, rotatable on trunnions 73 by a rod 86 connected to a servomotor 89. The gear 25 is connected to the clutch 40 through both the friction clutch 56 and a positive clutch 42, which, while the clutch 40 is being shifted, is disengaged by cams 96 on the yoke 76. These cams engage pins 51 mounted on pivoted hangers 97 and engaging a groove in the clutch 42. After the shifting of the clutch 40 has been completed, the cam 96 permits the clutch 42 to be drawn back into engagement by the springs 102. The servomotor 89 is operated by a valve 117 having a throttling screw 126 in the enginesuction conduit 116 to adjust the rate at which gear-change takes place. Specification 361,382 is referred to.
Patent GB-805930-A (GB)
Title: Adjustable inductance device
IPC: H01F17/04
Filed: 1956-11-09
Abstract: 805,930. Inductors. WESTERN ELECTRIC CO. Inc. Nov. 9, 1956 [Nov. 15, 1955], No. 34311/56. Class 38 (2). An adjustable inductor comprises a winding 32 disposed between two cup-shaped magnetic core parts 10, 11, bushings 16, 17 passing through central apertures in the core parts and having shoulders 14, 15 abutting the core parts, the outer portions of the bushings being externally threaded to receive nuts 18 for securing the core parts and bushings together, and a threaded central shaft 30 cut at opposed ends with different threads which engage corresponding internal threads in the bushings. Rotation of the shaft causes a differential movement of the core parts due to the different threads, and so varies the air gap between the core parts and hence the inductance. The winding is wound on a nylon bobbin 33, and the device is mounted on a resilient frame 27 which supports terminals 26 embedded in a block of resin. In order to counteract the increase in permeability of the core on rise of temperature the shaft, which is of stainless steel, expands to increase the air gap. A modification, Fig. 5, provides an arrangement whereby the effective expansion of the shaft may be adjusted so that a zero temperature coefficient of inductance for the device may be obtained. The bushing 57 and shaft 52 have different coefficients of expansion and their effective lengths are varied by moving a nut 64 which engages both of them. When correctly adjusted the overall change in length at a temperature change produces a change in inductance which is balanced by the change in inductance due to the increase in permeability of the core to give a zero temperature coefficient for the device. The core parts may consist of magnesium zinc ferrite. Specification 712,808 is referred to.

Title: Improvements in guiding means for annular flow of fluids
IPC: F15D1/00
Filed: 1947-12-31
Abstract: 673,062. Hydraulic turbines; radial-flow pumps. ABBEY, A. (Soc. Financiere d-Expansion Commerciale et Industrielle Soc. Anon Sfinder). Dec. 31, 1947, No. 34939/47. Classes 110(i) and 110(iii) [Also in Groups XI and XXIX] Annular flow of fluid takes place between two surfaces of revolution and a helical surface which has at least one thread. and is constant in pitch over the range of regulation, at least one of the surfaces having a helical movement with respect to the others with a pitch equal to that of the helical surface, for the purpose of regulating the flow. Fig. 8 shows a Kaplan turbine in which the inlet guide comprises a conical surface 1 and helical surface 3, regulation being effected by a screwing movement of :a control surface 2. In the turbine shown in Fig. 9, the control surface 2 is formed by the free surface 29 of the water or other working fluid. The free surface is adjusted by varying the pressure of air within a bell 25. Instead of air, mercury or other plastic liquid or gaseous merium which does not mix or emulsify with the working fluid and is substantially different in density from it may be used. Fig. 10 shows a turbine in which admission is regulated by simultaneous adjustment of members 40 and 41. The flow through the rotor is bounded at its inner periphery by a free surface 45, the position of which is determined by the volume of flow. The flow may be'directed outwardly instead of inwardly as shown. In the turbine (which may be modified to act as a pump) shown in Fig. 6, the working fluid from an annular nozzle 6 passes through rotor passages 9, 10 and is discharged through a pipe 12. Admission is 'varied by admitting pressure water to the space above a cover 24 so as to cause axial displacement of the rotor 17 and thus of a control surface 8 and a control member 11, both of which are carried by the rotor. To avoid impact losses consequent upon alteration of the pressure at the turbine inlet, the positions of a control member 7 with respect to the :surface 8 and of the control member 11 with respect to a surface 14 are automically regulated by the admission of pressure water to chambers 20, 21 and 22, 23 in accordance with the pressure difference set up at the inlet edges 18, 19 of the spiral surfaces of the rotor and charge pipe, respectively. The regulation of the spiral surfaces of the rotor and dismay be effected through a servomotor.

Title: Multichannel electric communication systems

Abstract: 656,149. Two-way transmission systems. STANDARD TELEPHONES & CABLES, Ltd. Dec. 31, 1947, No. 35122. Convention date, Dec. 4, 1944. [Class 40 (iv)] In a two-way wireless link in which the same carrier frequency is used in both directions, the signalling time is divided into successive elementary periods of time T equal to the transit time of the wireless waves, transmission taking place by both transmitters during the odd numbered elementary periods and reception by both receivers during the even-numbered periods. The signals to be transmitted are recorded on a storage target during a time 2T and recovered for transmission during a time T and vice versa for reception. The invention is described with reference to the multi-channel telephone system described in Specification 656,151, in which each channel is compressed in time and recorded during a different one of the horizontal scannings of an iconoscope, the recovery being effected by vertical scanning so that pulses representing successive channels are interleaved. Each horizontal line in the present system contains the channel signals for the period 2T, the recovery by vertical scanning taking place during time T at the transmitter, converse arrangements being used in the receiver. Line and frame synchronization is effected by the use of a super-audio frequency superimposed on all channels and interrupted at the end of each line and omitted for a line at the end of each frame. These pulses, subject to appropriate delay, may be used for synchronizing the transmissions. Carrier frequencies may be synchronized by isolating the carrier received from the master station, delaying and amplifying it and using it as the outgoing carrier. Alternatively stable crystal-controlled oscillators may be used.
