Title: Improvements in or relating to driving means for vehicles
IPC: F02B73/00
Filed: 1949-11-21
Abstract: 680,019. Gas turbine plant. TURBO AKT.- GES. Nov. 21. 1949 [Oct. 3, 1949]. No. 29724/49. Class 110(iii) [Also in Group XXVII] A gas turbine driving a vehicle is fed from a receiver supplied with gas under pressure by an internal combustion power gas generator having reciprocating pistons. Operation of a throttle controlling the gas flow to the turbine results in a pressure variation in the receiver which automatically produces variation in the fuel supply to the generator to maintain its operation at constant speed. The turbine rotor 73 is mounted on a shaft 70 which carries a brake drum 74 and drives the vehicle through a suitable change speed and differential gearing. The throttle disc 81 controls the flow of gas through the stator blades 89 and is actuated by the accelerator pedal through a Bowden wire, an arm 96, an axle 95 and a pinion 94. When the pedal is released brake checks 99 are urged against the drum 74 but when it is depressed the throttle 91 is actuated to restrict the flow of gas to the rotor whereby a governor 36 increases the fuel injection since the compressor consumes more power to overcome the build up of pressure in the receiver 12. The piston units 7, 9 are interconnected by an inclined disc gear or swash plate 24 which drives engine auxiliaries through a shaft 20. The drive set may comprise turbines working simultaneously with a single wheel drive or single axle drive or one or more turbines for forward speed and the remainder for reversing.

Title: Inking ribbon transport mechanism
IPC: B65H20/16
Filed: 1970-06-19
Abstract: 1309583 Ink-ribbon mechanism INTERNATIONAL BUSINESS MACHINES CORP 19 June 1970 [24 June 1969] 29788/70 Heading B6F A page-width ink ribbon 3 is fed in either direction between two take-up rollers 4, 5 which are driven alternately by an ink ribbon actuated reversal mechanism 9. The ends of the rollers 4, 5 opposite the reversal mechanism ends are rotationally mounted to the ends of a twoarmed lever 88. This enables the axes of the rollers 4, 5 to be set at a skew with respect to each other so that transverse registration of the ink-ribbon can be achieved. Mis-register of the ribbon is detected with a lever 64 pivoted to a double linkage mechanism (73, Fig. 6a). The mechanism (73) cyclically moves the sensing lever 64 into the plane of the ribbon. If the lever 64 contacts the ribbon 3, it is tilted over in a direction dependent on the feed direction of the ribbon, thus enabling the linkage mechanism to take a first of two possible positions (Figs. 6c to 6f). If, however, the ribbon has moved transversely away from the vicinity of the sensing lever 64 so that it contacts a stationary guide surface, then the lever 64 remains in an upright position defining the second position of the linkage mechanism (73). If, after a detecting cycle, the position of the mechanism (73) is the same as the previous cycle, the position of lever 88 supporting the rollers 4, 5, is not changed. If, however,-there is a change in the position of the mechanism (73), this results in a pivoting of lever 88 thereby reversing the skew of the rollers 4, 5. Pivoting of the lever 88 is achieved with an eccentric (89, Fig. 4) in one embodiment, and a crank (121, Fig. 7a) in a second embodiment. The reversal mechanism 9 includes a pair of dog clutches 29, 30 which are alternately engaged to drive one or other of the take-up rollers 4, 5 when reversal elements 12a, 12b carried by the ink ribbon 3 contact and move the ends of a two-armed reversal lever 13. When a dog clutch is disengaged, a leaf-spring (61, Fig. 2) fixed to the clutch disc acts against the inner surface of the stationary part of the dog clutch, and therefore brakes the take-up roller, which is acting as a supply roller for the ink ribbon being wound on to the other take-up roller.
