| A forestry machine includes a ground propulsion apparatus, a vehicle body supported by the ground propulsion apparatus, an operator seat disposed on the vehicle body, a first control lever operable by an operator sitting in the operator seat, a work implement including a saw, and a control circuit. The control circuit includes a first user input disposed on the first control lever. The first user input is operatively coupled to the work implement. Power to the saw is engaged upon the first user input being operated in combination with another operation. A method of operating a forestry machine includes operating a first user input disposed on the first control lever. Power is engaged to the saw in response to the first user input being operated in combination with another operation. | ||||||

| A low noise transconductance cell includes a resistor and a differential circuit pair having two equivalent half-circuits. Each half-circuit includes a feedback loop coupled to the resistor. The feedback loop includes an input transistor coupled to an inverting gain stage. The inverting gain stage is coupled to an output transistor which in turn is coupled to the input transistor and the resistor. In a low noise transconductance cell, a bias current source is coupled to the center of series connected resistors. In a high swing transconductance cell, a first bias current source is coupled to the left terminal of a resistance stage and a second bias current source is coupled to the right terminal of the resistance stage. The resistance stage can include a single resistor or a plurality of resistors. | ||||||
| 44 | Force transmission linkage for automotive vehicles | US589548 | 1990-09-28 | US5117958A | 1992-06-02 | Herve Focqueur; Bernard Jumel |
| A force transmission linkage for an automotive vehicle couples a control member with a manoeuvring member of a declutching device for a clutch, and is of the kind comprising a mechanical part with application points carried by a fixed part of the vehicle.In accordance with the invention, one of the said application points of the linkage is movable under the action of a control device comprising a motor and a transmission acting between the said motor and the said movable application point. A sensor for detecting a supplementary strain in the linkage, is provided together with a computer, with the computer receiving information signals from the strain sensor for control of the motor. | ||||||

| A force transmission linkage for an automative vehicle couples a control member with a manoeuvring member of a declutching device for a clutch, and is of the kind comprising a mechanical part with application points carried by a fixed part of the vehicle.In accordance with the invention, one of the application points of the linkage is movable in both directions along a course of travel which is defined between two limit positions and under the action of irreversible control device, which comprises a motor together with a transmission interposed between the motor and the movable application point. A position sensor is associated with the control member for detecting its free position when the latter is not actuated by the driver. Driving devices, comprising a computer and a detector, are provided. | ||||||
| 46 | Replacement lever | US767139 | 1985-08-19 | US4638681A | 1987-01-27 | John D. Eldridge, Jr. |
| A control lever for an automobile which is used to replace original equipment levers without requiring the removal of the dashboard. A preferred embodiment of the present invention includes a fork-shaped insert member slidable within a lever body, the insert having a pair of tines which are passed through a slot in the dashboard to engage a rotor plate behind the dashboard. By passing a screw through the lever body and threading it into the insert member from the front of the dashboard, the lever body and insert members are drawn together to clamp onto the rotor plate, securing the lever in place. Lateral movement of the lever within the slot will rotate the rotor plate, in order to select a desired function. Also disclosed is a method of replacing a climate control lever without removing the dashboard. | ||||||

| A MECHANISM FOR VARYING THE PHASE RELATIONSHIP OF A CAMSHAFT WITH RESPECT TO CRANKSHAFT. A DRIVEN MEMBER IS SECURED IN FIXED RELATIONSHIP TO THE CAMSHAFT AND IS CONNECTED THROUGH A HELICAL BALL SPLINE TO A PISTON MEMBER WHICH IS NONROTATABLY RELATED TO THE CRANKSHAFT. THE PISTON MEMBER AND THE DRIVEN MEMBER DEFINE A FLUID CHAMBER THEREBETWEEN. A SHIFTABLE VALVE MEMBER PERMITS FLOW OF FLUID TO SAID CHAMBER CAUSING THE PISTON TO MOVE AXIALLY RELATIVE TO THE DRIVEN MEMBER, WHEREBY THE HELICAL BALL SPLINE CAUSES THE DRIVEN MEMBER TO ROTATE RELATIVE TO THE PISTON, WHICH IN TURN CAUSES ROTATION OF THE CAMSHAFT RELATIVE TO THE CRANKSHAFT. THE VALVE MEMBER MAY BE CONTROLLED EITHER MANUALLY OR AUTOMATICALLY IN RESPONSE TO AN ENGINE OPERATING CONDITION.

| 48 | Apparatus for an endless adjustment of the working stroke of a driving machine | US3611836D | 1969-10-06 | US3611836A | 1971-10-12 | WECK WERNER |
| An apparatus for continuous adjustment of the working stroke of a driving machine, wherein the adjustment of the working stroke is simplified and rendered easier. A stroke adjustment spindle, mounted in a crank ring which is rigidly connected with a driven crank hub, in addition to manual operation, is further adjustable by an adjustment drive, preferably by a bevel gear drive, movable selectively in one or in the other opposite rotary adjustment direction. This adjustment is brought about by sitting the driving or control wheel of this double gear drive at one end of a control shaft, projecting axially through the driven crank hub and likewise driven with the latter, which control shaft is coupled for a joint drive at its counter end and is as well axially slidable on the latter. The control shaft receives an engaging element operable from the outside by means of an engaging lever arrested in the rest position and manually operable, which engaging element, depending upon the amount of the stroke adjustment, cooperates either with a coupling ring disc immovable in space, preferably on the side of the coupling housing, and disposed with an axial distance, for instance, on the left side from the engaging element, in the sense of a rotary locking of the double gear drive control shaft, or is provided with a second coupling ring disc disposed with an axial distance, for instance, on the right side from the engaging element, by means of an additional transmission drive driven from the crank hub with a peripheral speed higher than that of the crank hub in the sense of a bevel gear drive control shaft drive with its own driving speed surpassing the peripheral speed of the crank hub.
