Abstract: CONTACTLESS PRESSURE SENSITIVE SWITCH               Abstract of the Disclosure A contactless pressure switch sensitive to fluid pressure rates of change includes a housing and a diaphragm secured in the housing defining first and second chambers.  Ports are included in the first and second chambers to vent the chambers.  A magnet is secured to the diaphragm and a switching module is secured to the housing within one of the first or second chambers at a position spaced from the diaphragm.  A biasing magnet is mounted with the module to provide symmetrical switching by the module. The other of the first or second chambers is coupled to a source of signal pressure such that upon a pulse or rate change of pres-sure being introduced in the other of first and second chambers, the diaphragn is deflected.  This moves the magnet toward the module actuating it to switch the module and actuate a desired circuit.  In an alternative embodiment, the position of the module may be varied relative to the diaphragm to vary the sensitivity of the switch.

Abstract: Abstract of the Disclosure An apparatus for lifting logs from the ground to an elevated position in order to allow for cutting of the logs.  The log lifter comprises a lever arm having one end thereof bent downwardly to form a leg, the leg having on the end thereof a detachable support tube which serves as a fulcrum about which the lever arm may pivot.  The log lifting apparatus includes a first claw which is at-tached at the bend between the lever arm and the leg. The log lifting apparatus further includes a log grip-ping arm which is pivotably mounted with respect to the lever arm and which terminates in a second claw.  To lift a log that is lying on the ground, the lever arm is held in the upright position and the log gripping arm is pivoted in the withdrawn position so as to by ad-jacent to the lever arm.  The first claw is slipped under the log and the log gripping arm is then pivoted to provide for engagement of the log with the second claw.  The lever arm is then pivoted, preferably by man-ual means, about the support tube.  When the handle end of the lever arm is positioned adjacent the ground, the log is in an elevated position, the elevated position allowing for cutting of the log.

Abstract: TACHOMETER              Abstract of the Disclosure A tachometer for monitoring several functions on an imple-ment, such as engine, shaft and ground speeds.  A microprocessor receives a-c input signals which vary in frequency as the shaft or ground speeds change.  A time window syncronized with a rising edge on the desired input signal is provided during which the number of falling edges are counted.  A running total weighted average of a number of successive counts is used to update a digital readout indicating speed.  Each new count is compared with the previous average and, if a sudden speed change occurs, the processor shifts to a fast update mode in which the new count is used to immediately update the readout.  Programming switches are provided for selecting the proper ground speed time window for a given tire size and for providing a ground speed indication in either kilometers per hour or miles per hour.

By the conclusion of the braking zone, the operator member is unlatched from its home position, and the spring discharges to propel the operator member to its return stroke while re-establishing the full effective driving length of the link assembly, thereby rendering the operator member charging and return stroke lengths equal.
