Title: Process and device for automatically transmitting morse signals
Inventor: EMANUELS ERWIN JACOB
IPC: H03M7/40
Filed: 1966-09-20
Abstract: 1,149,103. Telegraphy. NETHERLANDS, POSTAL & TELECOMMUNICATION SERVICE, DIRECTOR GENERAL OF. 20 Sept., 1966 [27 Sept., 1965], No. 41932/66. Heading H4P. A Morse transmitter comprises a code converter which converts telegraph code signals read from a punched tape to Morse signals. Characters in telegraph code for which there is no equivalent in Morse are ignored and cause no interruption in the transmitted Morse signals provided that the number of consecutive unconvertible characters is at least one less than the number of dot periods in the preceding Morse signal. Characters read from the tape pass via a store to the converter (not described). The Morse signals from the converter pass via a shift register to a bi-stable output unit. A circuit recognizes each unconvertible character in the store and steps the tape. Detection of the Letter or Figure Shift characters causes a corresponding section of the converter to be actuated. Each Morse signal generated ends with three zero-state dot periods, providing character spacing. Thus letter A is generated as 10111000, so that in this case seven unconvertible characters may follow without causing interruption in the Morse output. If more than seven unconvertible characters had followed, a zero-state dot would be sent for each excess character. If a Line Feed character occurs and is not preceded by a Line Feed character, a hyphen, or a space, a Morse space signal (seven zero-state dots) is generated by adding four zero state dots to the last Morse character generated. When the tape reader is not operating a continuous 1010 dot sequence is transmitted. The first Morse signal to be sent is preceded by four 0 dots.

Title: An improvement in or relating to mechanical variable speed transmission mechanisms and traction vehicles provided therewith

Abstract: 1,046,851. Change-speed gears; band brakes. DAVID BROWN TRACTORS Ltd. Feb. 20, 1963 [Nov. 24, 1961], No. 42026/61. Headings F2D and F2E. In a change-speed gear for a tractor wherein two directreduced planet trains 10, 11 and a two-speed and reverse train 12 are arranged in series, each planet train comprises input and output suns 13, 16 (24, 27) meshing stepped planets 15 (26) which are clutched at 18 (29) to the input sun 13 (24) for direct drive, held by a brake 102 (118) for bidirectional reduced drive, and are held against reverse rotation by a one-way detent 23 (34) during ratio-shift to provide continuous torque transmission. Ratio-shift in the planet trains is effected without disengaging the usual main clutch (not shown) which precedes the gear. The friction clutches 18, 29 and brakes 102, 118 are liquid pressure actuated and a sequence valve (nut shown) supplies pressure liquid initially to the brake 102 (118) disengaging servo 110 and thereafter to the clutch 18 (29) engaging servo 19 (30) for upshift. The reduction ratios of the two planet trains are different so that the latter provides four ratio. The output sun 27 of the second epicyclic train 11 is fast with an intermediate shaft 35 carrying gear pinions 36, 112, 113 which respectively mesh pinions 38, 39 on an output shaft 40 and a reversing idler 114. The pinions 38, 39 are selectively clutched at 42 to the output shaft, to provide two forward ratios, whilst for reverse the idler 114 together with the pinion 113 is slid axially into mesh with a pinion 43 fast with the output shaft. Ratio shift in the gear train 12 can only be effected when the vehicle is stationary. A power take-off shaft 98 is provided. The brakes 102, 118 are similar and the former, Fig. 2, comprises a helical phosphorbronze band 102 adjustably secured at one end 103 to the casing whilst the other end is fast with a servo-piston 109 that is urged into the brake engaged position by a spring 108. The brake is released by supplying pressure liquid to the servo-chamber 110.
