Title: Differential transmission mechanism for meters, clocks, and other purposes
IPC: F16H48/08
Filed: 1933-10-19
Abstract: 422,076. Differential gearing. MAAG, W., 128, Albisstrasse, Zurich, Switzerland. Oct. 19, 1933, No. 28982. [A Specification was laid open to inspection under Sect. 91 of the Acts, April 23, 1934.] [Class 80 (ii)] [See also Groups XIX, XVIII, and XXVI] A transmission mechanism for actuating a counting-apparatus and for other purposes comprises differential wheel gears driven by two different sources and so coupled together as to drive a shaft in accordance with the difference in movement derived from the two sources. The driven shaft may actuate a counter or operate a switch or other control mechanism. The invention is applicable to prepayment meters, to apparatus for synchronizing alternating current generators and motors, and to means for synchronizing clock installations. As shown in Fig. 1, two sun wheels 2, 3, driven in the same direction from two different power sources, are loosely mounted on a shaft 1 and drive planet wheels 4, 5, to transmit movement through sun wheels 6, 7 to a common pinion 13 secured to a shaft 14. The planet wheels are mounted on shafts 8, 9 secured to a hollow shaft 10 on which the sun wheels 6, 7, are loosely mounted. The shaft 14 actuates a counter 15 or may operate a switch to open to close a circuit when the shaft is moved into a normal or zero position. As applied to a prepayment meter for radio apparatus. The insertion of coins into the meter and the operation of sun wheel 2 will cause the counter 15 to indicate the number of coins inserted. Switching on the radio apparatus will release a clockwork to drive the sun wheel 3 and cause the counter wheels to return to zero position whereupon a switch arm or cam on the shaft 14 will interrupt a circuit in the apparatus. In cases where the force acting on the sun wheel 2 or 3 is insufficient to effect its movement an auxiliary force may be employed. This auxiliary force acts to rotate the shaft 1 and to store up energy in an elastic member such as a spiral spring connected at one end to the shaft and at the other end to a ratchet wheel integral with the sun wheel. The movement to be counted is effective to release a pawl from the ratchet wheel and the tensioned spring causes the sun wheel to move. As shown in Fig. 2 applied to a clock installation comprising a master clock 20 and a secondary clock 21, the master clock is driven by a spring barrel 23 and regulated by a pendulum acting on a wheel 24 while the secondary clock is driven by a source of power such as an electric motor. A difference in the two movements is indicated by the numeral wheel 15. For synchronizing alternating current generators or motors 30, 31, Fig. 3, the shaft 14 driven through the differential gear operates a regulating member 32 controlling a switch 33 with co-operating contacts 34, 35 in regulating circuits.

Title: Improvements in or relating to electron discharge devices
IPC: H01J25/48
Filed: 1948-11-09
Abstract: 664,253. High-frequency discharge apparatus. WESTERN ELECTRIC CO., Inc. Nov. 9, 1948 [July 15, 1948], No. 29093/48. Class 39 (i). An electron discharge device comprises means for producing two electron streams, means for producing a space-charge wave to be amplified, the electron streams being coupled at points distributed along the streams such that the electron transit time between coupling points is different for one stream than for the other, and the current density being above the minimum required, whereby the space charge wave is amplified by interaction between the streams, there being means for abstracting energy from the amplified space-charge wave present in at least one of the streams. The growing space-charge wave may be set up in two electron beams which are side-by-side or intermingled, thus having components of at least two different velocities. In one form, cathode 11, Fig. 1, and negatively biased annular cathode 12 produce two concentric beams of differing velocities. Modulation is applied to both beams by helix 32 non-reflectively terminated by loss material 35 and fed with an input signal at tapping 36. The beams are focused by long magnetic coil 27 and pass finally through output helix 39. If it is desired to take the output from the fast outer beam only, a long extension 28 of the collector 43 may intercept the inner beam before it enters the helix. The metallic envelope 10 acts as an accelerating electrode, as does also electrode 22 between the cathodes. In modifications, the input and output circuits may be cavity resonators 45, 46, Fig. 4. The fast beam from cathode 11 is velocity-modulated by resonator grids 58, 59, and the slow beam is then added by filament 61 ; alternatively filament 61 or an indirectly-heated cathode is before the velocity-modulation resonator. Output may be taken from resonator 46, or a succession of resonators. In another form, Fig. 3 (not shown), the input resonator may density-modulate the beam from the first cathode which then forms part of its wall. The second cathode may be a grid 12, Fig. 5, heated by bombardment from the first cathode. The slow beam may be diverted from the output circuit by a biased grid 72, Fig. 8, by electrostatic or combined electrostatic and magnetic deflection, or by electrostatic or magnetic focusing through an aperture.
