Abstract: A shroud for use in combination with a septic tank having an access opening and an access cover. The shroud surrounds the access opening and facilitates removal of the access cover covering the access opening and providing access to the septic tank. The shroud comprises a contiguous sidewall opened at first and second opposed ends thereof with an access passageway extending therebetween. A first open end of the shroud has an annular surface for abutting engagement with a top surface of a septic tank. A retaining member retains the annular surface, at the first end of the shroud, in abutting engagement with the top surface of the septic tank. A removable shroud cover seals the second open end of the shroud and the shroud cover, when removed from the second end of the shroud, facilitates access an interior cavity of the septic tank.

Abstract: A method is proposed for controlling an automatic transmission driven by a prime mover in which a shift from a first transmission ratio to a second transmission ratio occurs in the form of a pull upshift or push downshift or a pull downshift or push upshift by a first clutch opening and a second clutch closing and an electronic transmission control device controls, via electromagnetic valves, the pressure curve of the first and of the second clutch during the shifting operation. The shifting operation is divided into various shifting phases, an engine intervention taking place in the load-transfer (LÜ) of the gradient-setting phase (GE), the sliding phase (GL), the gradient-reduction phase (GA) and the closing phase (S), an engine torque and/or a characteristic value that determines the engine torque being transferred from the transmission control device to an engine control device of the prime mover.

Abstract: In a method for controlling the multiplication for a continuously variable transmission with electrohydraulic control by means of a control loop having a linear PID controller with the specified multiplication of the variator iv_soll as command variable, the actual multiplication iv as regulating variable and the multiplication changing speed as correcting variable, the correcting variable delivered by the PID controller is limited to limiting values determined by the design for an upshift and downshift wherein said limiting values are calculated form the limits determined by construction and from the operating-point dependent limits determined by volume flow and the intersection of both admissible intervals determined by construction and by volume flow is defined as admissible multiplication changing speed range.

Abstract: A method for application of the operating behavior of a device for actuating in particular a transmission. Actuators of this device defined by data elements and stored in a constant memory value are controlled by an electronic control unit. It is proposed to optimize the operating behavior of the transmission resulting here as consequence of predefined initial data elements of the correcting parameters by associating, as needed, new data elements with individual correcting parameters. The basic structure of the initial data elements is here copied, then the new data elements are as needed written in the copy of the basic structure of the initial data elements and at the same time corresponding address reference is entered in the data section of the initial data elements which points to the new data elements.

Abstract: A motor vehicle suspension system includes rear suspension units to adjust ride height between sprung and unsprung parts of the vehicle, control means for monitoring and maintaining ride height at a particular setting and wheel speed monitoring means for monitoring wheel speeds. The control means provides a corrective up height change signal in the event of an unrequested height change and there existed before the unrequested height change a wheel speed signal indicative of vehicle movement. The corrective height change signal may be applied to each suspension unit or the control means may monitor abnormal vehicle activity and provide the corrective height change signal to the appropriate suspension unit. One example of abnormal vehicle activity is when the wheel speeds differ significantly, the control means responding to provide the corrective height change signal to the suspensions unit on the side of the vehicle with the highest wheel speed.

Abstract: The chain of an electromotive chain saw is quickly stopped by the combined use of an electric brake and a mechanical brake when a trigger member is turned off. The rear end of a brake band disposed to tighten a brake drum by operating a hand guard is secured to a bent rod. When the trigger member is released, the brake band is normally tightened around the outer periphery of a brake drum by the urging force of a coil spring. When the trigger member is released, a circuit provided with a brake winding is closed, thereby applying a dynamic braking force. When the dynamic brake force is applied, a centrifugal clutch is released quickly and the speed of stopping the brake drum is accelerated.
