Title: Improvements in or relating to telegraph keyboard mechanism
IPC: H04L17/04
Filed: 1937-02-26
Abstract: 489,513. Type-printing telegraphy. GRIFFITH, R. G. Feb. 26, 1937, No. 5899. [Class 40 (iii)] A keyboard telegraph transmitter, in which keys set up permutations in selector members, has loaded transfer mechanism such that, triggered by the depression of a key and under the action of the loading means it transfers the permutation to a further set of selector members. Depression of a key 1, Fig. 1, tilts six pivoted vanes 3 in one direction or the other by means of a selector frame 2, so raising or lowering corresponding selector slides 10. An additional vane 3a, Fig. 2, tilted clockwise by the depression of any key, by lifting an arm 13, raises a slide 12 and with it a latch 14. This raises a lever 20 and with it, by means of a lug 24, a latch 23 which, slipping over a projection 26, allows a transfer member 27 to move in a clockwise direction under the action of a spring 29. A projection 31a or 31b of each of six T-members 31, moved to the right with the member 27, strikes a projection 10a or 10b on the selector slides 10 and the resultant tilting moves corresponding selector bars 50 by means of bellcranks 48, either to the right or left. If a bar 50 is moved to the left a projecting piece 55 raises a corresponding lever 51 so that, on the rotation of the transmitting cams 44, its further end is depressed, the movement being communicated to suitable transmitting mechanism. When the transfer mechanism is tripped the movement of the transfer member 27 is communicated by a link 32 to a bell-crank 33, the initial movement of which allows the camshafts 45, 46 to rotate by releasing connected detents 36, 39. A cam 56 on the shaft 45 resets the transfer mechanism by co-operating with a roller 57 carried by the bell-crank 33. The use of a spring-loaded latch 14, having a step 14b, which is moved in a clockwise direction by the transfer lever 27 when tripped enables this lever to be reset even if the key is held depressed after a character is transmitted. If the apparatus is fitted with a code drum 66 for transmitting a predetermined signal a lever 69 may be caused to hold the slide 12 depressed during rotation of the drum so that depression of any key is ineffective on account of the spring connection 16 of the arm 13. The cam shaft 46 is driven by a slipping clutch slightly faster than the cam 56 and is stopped after each half revolution by a detent 60 which is released by a cam 58 when the shaft 45 has completed half a revolution. Specifications 442,177, 447,196, 448,846, 461,753, and 476,123 are referred to.

Title: Fluid pulse generator
IPC: G04F5/12
Filed: 1963-02-14
Abstract: 1,027,817. Fluid amplifiers. SPERRY RAND CORPORATION. Feb 14,1963 [Feb 16, 1962],No 5949/63. Heading G3H. A fluid pulse train generator comprises a pure fluid amplifier with an inlet 11 for pressure fluid and a nozzle 13 the discharge from which passes alternately to channels 16,17, a pulse being delivered to an outlet 32 each time the discharge changes from one channel 16 or 17 to the other. Fluid discharging through either channel 16,17 tends to continue to discharge through that channel, due to the creation of a low pressure boundary layer region at the wall 14 or 15, until it is deflected by a control jet from a nozzle 22 or 25. Each control jet is connected to a channel 16 or 17 and becomes effective to deflect the main discharge when a predetermined pressure is established in the channel to which it is connected. By adjusting the setting of pressure sources 26, 27 connected to the channels 16, 17 the time taken for the pressure in a control jet to reach the value necessary to deflect the main stream, and hence the frequency of pulses delivered to the outlet 32, can be varied. Unequal intervals between pulses can be produced by adjusting the sources 26, 27 to different pressures and/or by designing the control nozzles 22, 25 to cause change-over at different pressures. Acute changes in the slope of the walls 14, 15 may be provided at regions, 18, 19. In a modification, in which such changes are omitted, tappings from the channels 16, 17 are taken from points upstream of the tappings for the control nozzles 22, 25 and are led to nozzles which assist in holding the discharge to a channel until their effect is overcome by the control nozzles. The pulses at the outlet 32 may be used for any device which employs a train of clock pulses.
