Abstract: A picking mechanism may include a mechanical reference system for establishing the approximate number of sheets that will be “picked” from a larger stack each time the picking process occurs. A pick moves toward the stack of paper to insert itself between two sheets of paper at a level in the stack that is determined by the place the pick resides relative to the stack. In the preferred embodiment, the pick resides at said position because it is positioned at a adjustably fixed relationship to a reference member and the reference member rests on the top of the stack of paper when the pick is in a retracted position. Thus, the vertical distance between the reference member (and the top of the stack) and the point (edge) of the pick determines how many sheets will be picked at a time.

Abstract: A travel speed limiting control system for lift trucks, particularly of the "orderpicker" type, having an extendible mast, is disclosed. The truck travel speed which the operator can command is limited by factors including load weight, load elevation, heading angle and direction of truck travel (forward or reverse) . Optionally, other factors may be involved, such as lateral tilt and load moment. An algorithm including the desired input factors is continually processed by an on-board microcomputer to provide an instantaneous speed limit signal. In addition to its normal operating mode, the microcomputer is also arranged to operate in a "learn" mode, whereby it runs through the ranges of various input signals and develops a set of stored values which indicate the allowable ranges of the inputs, as well as offset or bias values which compensate for manufacturing tolerances occurring in the components of the system.

Abstract: Apparatus for measuring or otherwise checking phase angles between different lines of a multi-line fuel injection pump for an internal combustion engine, comprising an injector block defining a plurality of cavities. These cavities receive the nozzle ends of the fuel injectors of the different lines. Pressure sensors are arranged in communication with the cavity interiors to detect changes in pressure therein, and means are connected to the pressure sensors to provide a measurement of, or other check on, the phase angles of the different lines.
