Granted: 1989-09-13
Abstract: PCT No. PCT/JP86/00064 Sec. 371 Date Oct. 7, 1986 Sec. 102(e) Date Oct. 7, 1986 PCT Filed Feb. 14, 1986 PCT Pub. No. WO86/04865 PCT Pub. Date Aug. 28, 1986.An automatic transmission apparatus comprising a friction clutch (31) coupled to an output shaft of an engine (30), a clutch actuator (42) for operating the friction clutch, a parallel shaft type gear transmission (32), the input shaft of which is coupled to the friction clutch, a gear position changer (51) for changing the speed ratio of the transmission, and a rack actuator (38) for operating the control rack (35) of a fuel injection pump. A signal from a drive state-detector is used to determine a change in the speed ratio of the transmission (32). The rack actuator (38) gradually moves the control rack to an idling speed position, after which the clutch actuator disengages the friction clutch (31). The gear position changer (51) is operated in accordance with the disengagement of the friction clutch (31), so that the speed ratio of the transmission is changed accordingly. The control rack (35) is moved, so that the rotational speed of the output shaft (30) substantially coincides with the input shaft of the transmission (32), and the clutch actuator moves the friction clutch (31) in the engagement direction. When the difference in the rotational speed of the output shaft (30) and the input shaft of the transmission, has decreased below a predetermined value during the operation of the clutch actuator (42), the rack actuator (42) gradually moves to a position corresponding to the degree of depression of the accelerator pedal.

Title: Method and apparatus for crop spraying
Inventor: BENEST ROGER SYDNEY
IPC: A01M/
Filed: 1992-07-23
Granted: 1995-11-01
Abstract: A dropleg row crop sprayer (12) senses boom height and tilt from ground-contacting droplegs (46) signalling through potentiometers (74, 76) to a boom control mechanism (84). The droplegs follow crop row wandering through a driven carriage (44). Dropleg attitude is assisted by a cam control system (94, 96). The boom (20, 21) floats through a spring suspension system (128, 138) and is damped by frictional abutment of the boom portions (20, 21), thereby permitting a single actuator (106) to control attitude. A lost motion linkage (126) protects the actuator (106) from snatch loads. Spray control is effected by use of microdroplets discharged from the droplegs (46) below the row crop leaf canopy which protects the droplets from wind turbulence, while electrostatic charges and droplet-energising air flow act to assit crop coating. Where conventional spray droplets are used, the spray direction is fore/aft of the row to minimize ground speed effects. <IMAGE>
