Title: An improved hydraulic power lift mechanism for tractors
Inventor: HORSFALL HARRY
IPC: A01B63/111
Filed: 1962-12-30
Abstract: 983,099. Tractor power lift mechanisms. DAVID BROWN TRACTORS Ltd. Dec. 30, 1963 [Dec. 30, 1962], No. 25170/62. Heading A1P. In a tractor hydraulic power lift mechanism fluid is supplied by a pump 10 through a flow divider 13 and conduit 14 and, when poppet valve 42 is open, through conduit 41 to sump but when valve 42 is closed the pressure built up in conduit 14 opens non-return valve 47 to supply fluid to the ram cylinder 46 via conduit 45. Fluid can be exhausted from the ram to sump through a further poppet valve 50. Both poppet valves have restricted passages 54, 55 for the passage of fluid and are controlled by a slide valve 59 which moves to selectively block off the rear of the valves so that equal pressures build up on both sides of the valves which are thus closed by their respective springs 52, 53 or else the slide valve moves to connect the rear of the valves to sump through conduit 65 and thus allow a pressure on the faces of the valves to open them. The slide valve is moved by a lever system including a follow-up lever 79 connected to a lift link 76 and adapted to be moved either manually by lever 91; in response to draft control by a top link 70 operating a lever 89; or by the height of the lift links which move the lever 79 directly. In each case the lever 79 returns the slide valve to the neutral position shown, as the lift link 76 moves. Relief valve 68 limits pressure in the ram cylinder. The flow divider comprises a spring-biased valve spool 18 having a central bore and outlet 25 allowing fluid to pass through conduit 15 to a hydraulically operated gear selector mechanism and having holes 26 feeding a dashpot 27 and operates to keep the pressure of fluid in conduit 15 constant. A manually operated valve 33 allows pressure fluid to be diverted to auxiliary apparatus via conduit 37. Pressure relief valves 28, 30 are incorporated for both the pump and the conduit 15. Specification 964,968 is referred to.

Title: A new and improved method of and arrangement for drying material by utilising the heat of vapour evolved from the material
IPC: F26B17/08
Filed: 1939-09-09
Abstract: 532,829. Drying grass &c. TRIGGS, W. W. (Akt.-Ges. Brown, Boveri & Cie.). Sept. 9, 1939. No. 25509. [Class 34 (ii)] Materials particularly agricultural products such as grass are dried by passage through at least two drying chambers one of which has an external supply of heat while the others are heated by heat exchangers supplied with air saturated with vapour mixture from the first drying chamber, and fans circulate fresh air over the heat exchangers and material to be dried so often that at least 50 times as much air by weight passes over the heat exchangers as vapour flows through them during the same time. Grass is fed at a on to a conveyer b at the end of which it falls on to a conveyer f which carries it to an outlet n. The lower conveyer is heated by steam pipes k and vapour given off by the grass is drawn by a fan o into pipes i forming a heat exchanger in the compartment c containing the upper conveyer b. Air is circulated quickly and repeatedly by fans extending along the whole length of the chamber quickly over the 'pipes i and through the grass, thereby condensing moisture in the tubes. In a modification. the conveyers are slightly inclined and the heating pipes are at the upper end of one conveyer. The pipes may be above or at the side of the conveyer.

Abstract: 806,456. Exciting dynamo-electric machines. IGRANIC ELECTRIC CO. Ltd. Sept. 15, 1955 [Sept. 30, 1954], No. 26432/55. Class 35. [Also in Group XXXVII] In a diesel-electric traction system, an exciter E having a field winding f is connected to the field winding F of the main generator G, the diesel engine DE driving both the exciter and the main generator. Rheostats 6, 9, are adapted for connection in the circuit of the winding f and have their taps 5, 8 simultaneously adjusted in accordance with changes in speed and load on the engine by means of a governor 15. When a master controller 16 is moved to an " accelerating " position, contacts S1, S2 engage so that the exciter field winding is connected in series with rheostat 6 which has a non-linear characteristic with regard to its ohmic value per unit length, Fig. 2 (not shown). The resultant variation in the exciter field current is arranged to be suitable for operation of the main generator when it is supplying the traction motors during acceleration and normal running periods. Adjustment of the controllers 16 to a " dynamic braking " position causes contacts S1 S3 to engage whereby rheostat 9, having a linear characteristic, is connected in parallel with the series combination of resistor r and field winding f so that a change in series resistance afforded by rheostat 6 is combined with a variation of the parallel branch resistance. The variation of energization of the exciter field winding affords, under these circumstances, zero excitation in one extreme position of the rheostat taps, which is desirable for dynamic braking operation, Fig. 3 (not shown).
