Title: Crop threshing mechanism
IPC: A01F12/10
Filed: 1981-12-04
Abstract: In a crop threshing mechanism comprising a threshing cylinder 3 located adjacent a concave 6 and driven to thresh crop fed tangentially between the cylinder and concave, a crop conveyor, in the form of a roller 27 or continuous band conveyor 39, is located along the leading edge of the concave with respect to the crop feed direction so that crop passes over it to the cylinder and concave, and a changeable speed drive mechanism drives the conveyor and allows its speed to be changed, thereby to control the speed of crop flow. A crop guide flap 34 is provided adjacent the conveyor to vary the angle at which the crop is fed to the cylinder. The concave, conveyor and crop guide flap are all mounted so as to move about the axis 17 of the cylinder. <IMAGE>

Title: Electro-mechanical position servo means
Inventor: BRIGNALL NICOLAS LAURENCE
IPC: G01C19/42
Filed: 1985-04-17
Abstract: An electro-mechanical position servo means includes a motor 10 driving a load 11 about a load axis 19, the position of the load being determined by a gyroscope arrangement 26 which provides feedback signals to close the servo loop at motor driver 12. The gyroscope 26 comprises a rate integrating gyro 13 including load angle pick-off 22 and torquer coil 21'. The pick-off output is fed back by way of amplifier 41 to torquer coil input 27 to form a gyro feedback loop, the inherent integration effected by torquer coil causing the pick-off signal, and gyroscope output signal, at 27 to be in the form of a rate or velocity signal. Two servo feedback paths are formed, a velocity feedback path 28 feeding directly to a summing junction 30 before the motor driver 12 and a position feedback path 31, 35 to the summing junction 30 including an integrator 33 of the gyroscope signals and an input summing junction 32 by which position demand signals are input at 36 as a function of position rate of change. Instead of a rate integrating gyro 13 with its gyro feedback loop the gyroscope 26 may comprise a rate gyro. <IMAGE>

Title: Motorised golf trolley wheel
Inventor: WRIGLEY DENNIS VINCENT
IPC: A63B55/60
Filed: 1985-06-25
Abstract: A golf trolley wheel includes an electric motor (18) within the wheel body (32) and mounted on spindle (10) so as to rotate the wheel when energised. The electric motor (18) is energised from a battery (not shown) which may be mounted on the golf trolley or within body (32) of the wheel, by way of a tilt switch (not shown) upon the trolley being tilted for moving, with the result that belt (40) is driven in the direction of arrow (52) and friction roller (45) turns the wheel. The frictional engagement between the roller (45) and the body (32) is increased by reason of the roller (45) carried by carrier plate (26), which is pivotally mounted on sleeve (10) by hinge (20), being pressed progressively more firmly against the body (32) due to pivoting of the plate (26) about the hinge's axis. This arrangement provides a "freewheel" action, if the trolley should be pushed faster than it would be driven by the motor (18) or if the battery should become exhausted. The wheel body may incorporate a rechargable battery so that the whole wheel is removed for battery recharging. Both trolley wheels may be driven. <IMAGE>
