Patent GB-1488673-A (GB)
Title: Variable output transmission
IPC: F16H35/02
Filed: 1974-09-17
Abstract: 1488673 Change-speed gear KER-TRAIN SYSTEMS NV 17 Sept 1974 [26 Sept 1973 11 Sept 1974] 40359/74 Heading F2D An infinitely variable transmission comprises a spool rotatable by an input shaft and carrying a plurality of gear train loops arranged around the input shaft axis and sharing common first and last gear elements, each loop including a differential gear train, an overrunning clutch, at least two pairs of variable-ratio gears, i.e. gears of non-circular form, and a pair of constant profile, i.e. circular, gears. Fig. 8 shows part of such a transmission, the spool and input shaft being omitted and only one loop being shown. The spool is rotatable by the input shaft about the common axis of the output shaft 6 and a fixed reaction shaft 20 on which is fixed one non-circular wheel 9 of a variable-ratio gear pair, the other wheel 10 of which is fast with a side wheel 15 of a bevel differential train. Mounted on the shaft 20 is a tubular shaft 21 to which is fixed a non-circular wheel 9A in mesh with a wheel 10A fast with the other differential side wheel 17. The carrier 13 for the differential pinion 14 is connected through an overrunning clutch 19 with a circular wheel 4 in mesh with a circular wheel 5 on the output shaft 6. The gear pairs 9, 10 and 9A, 10A are similar and their phase relationship is adjustable by a thumbscrew 24 to vary the overall transmission ratio. With the wheels 9, 9A 180 degrees out of phase, as the spool carries the differential train about the axis 6, 20 the varying speeds applied to the side wheels 15, 17 cancel out in the differential train and the overall transmission ratio depends merely on the relationship between the ratio between the wheels 4, 5 and that between the wheels 9, 10 and 9A, 10A. This may be a 1 : 1 relationship resulting in zero rotation of the output shaft 6. Adjustment of the wheels 9, 9A to, e.g. a 90 degree phase relationship results in the carrier 13 varying in speed as the spool rotates such that for one quarter turn of the spool the carrier will impart rotation at constant velocity through the overrunning clutch 19 to the wheel 4, and with four similar loops equally spaced around the spool, the respective overrunning clutches 19 will take up the drive in succession to drive the output shaft continuously. The overrunning clutch may alternatively be associated with the wheel 10A. Also the arrangement may be modified such that the wheels 10, 10A are fast with the carrier 13 and the side wheel 15, respectively, and the side wheel 17 is connected with the wheel 4. Constructional forms of the transmission with three non- circular gear pairs and with hydraulic means for adjusting their phase relationship are described and illustrated.

Abstract: 1,044,549. Selective lift control. HITACHI Ltd. Oct. 16, 1963 [Oct. 19, 1962], No. 40896/63. Heading B8L. A multi-car lift control system comprises a CAR SELECTOR CIRCUIT, Fig. 6 (not shown), responsive to landing calls to select one car at the parking floor as a main car to respond to the call, and any subsequent calls, and a DIRECTION SELECTING CIRCUIT, Fig. 5 (not shown), which provides for the main car to answer calls ahead of it, but starts another car from the parking floor in response to calls from landings behind the main car in operation. Cars STOP READY at the floor at which passengers alight. The stop ready circuit is illustrated in Fig. 2 (not shown). As described with reference to a two-car system serving six floors with parking at the first floor, assuming the main car is car A stopped ready at the 3rd landing, it accepts directly up calls from the 4th and 5th landings, but with down calls from the 4th and 5th landings it goes. first to the top (6th landing) and then stops on the way down. If. a down call is registered from the 2nd landing the main car A answers it, but car B is also started up; B does not accept the call because it is not in its direction of travel but stops ready at nearest landing when absence of call is indicated after A serves 2nd floor. If an up call is registered from second landing, B answers, car A starts down and stops ready at nearest floor when absence of call is indicated. A timing relay dispatches car B if A fails to answer a call within a predetermined time.

As shown, a carriage 1, carrying a load 2 and mounted on a machine (not shown) for sliding movement on girders 14, includes a shaft 6 which extends through a part 8 fixed to the machine and terminates in a plate 10. The part 8 is provided with annular grooves 13 in an outer wall 12, for O-ring seals 14 which, in the position of the carriage plate 10 shown, forms spaces 16 between the plate and the wall 12. These spaces are connected through conduits 28 with solenoid controlled valves 30 which can be connected to a vacuum pump 32 or to atmosphere. The carriage 1 is biassed away from the position shown, by springs 36 which in operation of the device, are compressed as the plate 10 and the wall 12 are moved towards one another by hydraulic rams 38 housed within the part 8. The spaces 16 are then evacuated by the pump 32 and-the pressure in the rams relieved. To withdraw the carriage, the valves 30 are operated to connect the spaces 16 to atmosphere and the plate 10 is then moved away from the wall 12 by the springs 36. Movement of the carriage in this direction is damped by the rams, piston rods 40 of which are engaged by projections 44 on the carriage.
