Abstract: A computer system used for carrying out engineering tasks as a part of an engineering project. The system includes a plurality of client computers and one or more server computers accessible by the client computers via a communications network. Distributed across these computers is a multi-tiered software system that includes system programs, application programs, and database programs. The system programs include a system objects module, a job manager module, an event manager module, and a workbook module. The system objects module provides security and authentication services. The application programs carry out at least some of the engineering tasks. The job manager module manages use of the application programs. The event manager module receives and distributes notifications between at least some of the modules. The workbook module provides a user of the application programs with engineering information related to one or more of the engineering tasks.

Abstract: An engine mount for mounting an automotive vehicle engine to the automotive vehicle chassis. The mount comprises a vibration isolator portion which is designed with relatively low stiffness to provide increased vibration isolation. Excessive displacements are avoided by snubbers. Snubbing action in one direction is provided by a circular snubber that is disposed in spaced relation to the vibration isolator portion. Snubbing action in other directions is provided by the particular design of the vibration isolator portion. Embodiments of both a front and a rear engine mount are disclosed.

Abstract: The system is provided for actively controlling the pitching of a truck cab. The system includes sensors and a single point hydraulic actuator mounted at the rear of the cab between the cab and the frame on which the cab is mounted which is computer controlled and activated in accordance with calculations provided by an algorithm programmed into the controller in response to cab or frame pitch acceleration signals received from the sensors. A feedback circuit is also provided which verifies activation of the actuator in accordance with the calculations provided by the algorithm being run in the controller.

Abstract: An integral exhaust pipe and mounting bracket for use with the engine exhaust system of medium or heavy duty trucks which have a structural framework. A mounting plate is secured to one end of the exhaust pipe and mounted to the structural framework of the truck. The opposite end of the exhaust pipe is oriented generally vertically generally parallel to the wall of the truck cab but otherwise free standing. A lateral brace bridges the mounting plate and the opposite end and is secured therebetween. The exhaust pipe, mounting plate and lateral brace complete the integral mounting bracket with the exhaust pipe being utilized as a structural member instead of being a nonstructural mass attached to a bracket and supported as a dead weight thereon.

Abstract: A mirror vibration absorber for mirror assemblies mounted on motor vehicles comprises a ballast absorbing the vibration of the mirror assembly and disposed either inside or outside thereof. The position and weight of the ballast can be adjusted to the specific vibration frequency of the mirror assembly. The adjustment of the ballast position is made either by moving the adjustment of rods secured to the ballast relative to the mirror assembly or by moving the ballast relative to the adjustment rod. The ballast absorbs the mirror vibration and thereby reduces the need for reenforcing mounting hardware and braces.
