Title: Control systems for a vehicle such as a locomotive
IPC: B61C9/16
Filed: 1971-11-17
Abstract: 1363639 Hydrostatic transmission control; linkwork HUNSLET (HOLDINGS) Ltd 17 Nov 1971 [28 Dec 1970] 61389/70 Headings F2D and F2K The ratio control lever 38 of a hydrostatic transmission for a vehicle (a locomotive in the embodiment) is controlled by two pneumatic rams, 10 and 14, one (10) pivoted at 12 on the vehicle and extended in dependence on the engine throttle control (58) opening, the other fixed to the vehicle and extended in dependence on the vehicle speed through a governor 80. In operation, if one of the throttles 58 is opened, with toggle valves 56 closed, the resultant air passes to both cylinder 10 and engine throttle adjusting cylinder 64, the cylinder 10 extending the ram 16 between the end of which, and ram 10 a link 24 is pivoted with a strut 26 connected between it and a bell crank 32 to which the ratio control lever is connected by a push rod 36. As a result of this extension of the ram the ratio is increased (output to input speeds) and the vehicle starts to move, which in turn adjusts the cylinder 14 to further increase the transmission ratio until eventually, at maximum speed, the control lever is at position 38A, the letter A showing the position at this point of the other parts of the linkage. On closing the throttle 58 (two are shown because the locomotive may be operated from either end) the cylinder 10 retracts but, due to the continued extension of cylinder 14, the transmission ratio is only slightly decreased so that a large overrun is prevented, further decrease in transmission ratio occurring as the vehicle slows down. The strut 26 incorporates a piston and cylinder 27 the extension of which is controlled by toggle valve 56 so that on meeting, say, an up gradient, closing of the toggle valve (normally opened after the locomotive has started from rest) causes a slight decrease in transmission ratio. For reversing the vehicle valves 46 control, through shuttle valve 52, a double acting ram (not shown, or further described). The pneumatic lines shown by chain lines are for interconnection of the locomotive with another, so that a control point on one locomotive can control the systems of both.

Patent GB-663276-A (GB)
Abstract: 663,276. Rotary distributers. LUCAS, Ltd., J. Jan. 19, 1950. [Feb. 7, 1949] No. 3292/49. Class 38 (v). [Also in Group XXVII] For use in an electric spark ignition system for internal-combustion engines of the kind in which a condenser b, Fig. 1, or each of a plurality of condensers is charged from a magnet or ignition coil or like energy source and subsequently discharged across a sparking plug a after a predetermined voltage has been attained by the condenser b, there is provided a distributer comprising a rotary member g and an arrangement of electrodes h adapted to form separate condenser charging and discharging spark gaps. The "jumpspark" distributer is provided with a double set of four fixed contacts,h, Fig. 1, so that each of the four condensers b connected between one side of the secondary winding d of an ignition coil and one of the inner distributer contacts, are charged in turn across the distributer gap, the rotor arm g being connected to the other side of winding d. Upon a given condenser reaching a predetermined voltage it discharges between the fixed contacts h and causes energisation of the sparking plug a connected to the corresponding outer fixed contact. In a modification, the four condensers are replaced by a single condenser which is both charged and discharged each time the rotor arm comes opposite a stationary contact. Each inner distributer contact is formed with a through hole so that when a discharge occurs between the rotor and another distributer contact it also ionises the gap between the stationary contacts. In another modification, the contacts h, Fig. 3, only two pairs of which are shown, are arranged in an insulating enclosure whilst each outer contact is connected to a further contact j with which the rotor arm g co-operates, the single condenser b being charged across the gap between members j and g ; when the condenser is fully charged the discharge between these latter members ionises the gap between the contacts h to ensure prompt discharge thereof and hence energisation of the associated sparking plug a. In a further modification, the rotor arm consists of an annular screen k, Fig. 4, having an opening m in its periphery to house a charging gap n whilst around the screen are disposed the pairs of contacts h, a discharge across gap n causing ionisation of the particular contacts h that are opposite the opening m so that the condenser b can discharge therebetween when the required voltage is reached. In all instances the sparking plugs are preferably of the low-voltage type.
