Abstract: A vibratory compacting machine has a supplemental member resiliently mounted on the frame of the compacting machine. The supplemental member has a resonant frequency that is substantially equal to the operating frequency of the vibratory compactor and effectively reduces the frame vibration. As a result of reduced frame vibration, the present invention provides increased operator comfort and extended service life of electronic, electrical and mechanical components mounted on the compacting machine.
Abstract: An improved arrangement of a hydraulically-actuated injector fuel system is disclosed for an engine having an engine member such as a cylinder head. The system comprises a hydraulically-actuated injector positioned in a injector bore defined in the cylinder head and apparatus for supplying hydraulically actuating fluid to each injector. A hydraulically-actuated injector fuel system requires apparatus for communicating fuel and actuating fluid to each injector. An engine equipped with externally disposed actuating fluid and fuel lines exhibits a complicated and costly construction which is difficult to service. The present invention provides separate actuating fluid and fuel manifolds or passages which are internally disposed in the engine. This hidden and integrated arrangement is not only esthetically pleasing but simplifies assembly and disassembly of the engine and also permits a reduction in cost of the engine.

Abstract: A fuel system valve has a metal valve seat and a metal valve body. The metal valve body has a chamber which contains material which is moveable through the chamber in response to deceleration of the valve body. The forces of the material within the chamber on the valve body during rapid deceleration of the valve body counteract the forces subjected on the valve body in response to contact with the valve seat.

Abstract: A fluid system of an internal combustion engine has controls and a separate radiator for maintaining the temperature of incoming engine combustion air at optimum conditions.
Abstract: An apparatus for measuring gaseous blowby a piston of an operating internal combustion engine. The apparatus have a heating and filtering system which function to increase the accuracy of the resultant measurements. The orientation of the conduit, flow meter, and the control of oil sump pressures also contribute to improved accuracy and ease of operation.
Abstract: An apparatus and method are provided for cleaning exhaust particulate from a contaminated vehicle exhaust gas filter. Regeneration gases, oxygen content, and input heat are controlled in order to efficiently control the heat of regeneration.
Abstract: A work machine control assembly has a plurality of actuating levers each associated with a respective actuating element for controlling respective movements of a work implement of the work machine, for example an excavator. The control assembly of this invention has a cam operated moveable gate which captures portions of the actuating elements and controllably locks them in a preselected position in response to actuation of a lock actuation lever.

Abstract: A multi-tool apparatus is useable for hobbing cylindrical blanks using a tool that has an axis of rotation that extends parallel to a line perpendicular to an axis extending through the center of the blank. The tool and the blank are both rotated during the cutting operation. The tool is spaced from the axis of rotation of the blank and linear movement of the tool is only in a direction parallel to the axis of the blank.
Abstract: A bistable pneumatic valve assembly has a valve containing a flange and is adapted to be associated with a combustion chamber of an internal combustion engine. A control outlet opening of the valve assembly housing is opened for responsively causing the valve to both open and close for controlled passing of fluid from the valve assembly.
Abstract: An apparatus adjustably controls intake and exhaust valve movement and fuel injection of an engine. Valve movement and injection is adjustably controlled in response to electrical signals delivered to a piezoelectric motor which in turn delivers hydraulic signals through a single spool valve.

Abstract: An apparatus for a multi-fuel system has a recirculation conduit passing excess fuel back to a mixing chamber where it is mixed with incoming fuel and thereby preventing abrupt fuel composition changes associated with switching from one fuel to another.
Abstract: This invention relates to apparatus for determining the energy content of a fuel and delivering an engine controlling signal responsive to the determined energy content.
Abstract: A frequency/speed controller is provided for controlling the frequency or speed of a device by comparing the frequency of the device to a known reference frequency and matching the device frequency with the reference frequency. The controller uses an up/down counter whose count at any given time is the digital quantized form of ##EQU1## where f.sub.1 and f.sub.2 are the frequencies to be matched.
Abstract: An apparatus (38) for tilting a pivotally mounted vehicle operator cab (21) has an actuator (40) for exerting a tilting force, a link (60) for directing the tilting force in a direction substantially perpendicular to the longitudinal axis (58) of the actuator (40), and a strut (46) for absorbing a substantial portion of the tilting force to prevent damage to the vehicle elements.

Abstract: This invention relates to a holding assembly (10) for connecting a shaft (20) to a drive member (16), the holding assembly has a body (12), first and second end portions (14,18) and a middle portion (21), a member (52) is connected to the body (12) at the middle portion (21) for selectively controllably deflecting one of the first and second end portions (14,18) to preselected relative positions and eliminating runout in the shaft (20). The holding assembly (10) is particularly useful on a boring machine.
Abstract: An engine control wherein a shaft driven by the engine causes a first signal to be generated and then a second signal after the shaft has rotated through a predetermined degree. The first signal starts a timer into operation, the timer producing a timer pulse of predetermined duration. Time coincidence of the timer signal and second signal indicates that a critical engine speed has been reached and such time coincidence is used to effect a control function. If the shaft rotates in the opposite direction the sequence of generation of the first and second signals in such direction is detected and used to generate a reverse-direction signal which is used to effect a control function. An automatic impedance-changing circuit enables the control to be used with a wide range of batteries.
