Abstract: A steering system functions in accordance with the “steer by wire” concept and has a normal operating system without positive coupling between the steering handle and the steered vehicle wheels, as well as an emergency operating system, which functions with positive coupling between the steered vehicle wheels and the steering handle. An auxiliary operating system is additionally provided, which, in response to malfunctions of the normal operating system, assumes its tasks and, in a transitional phase, adapts the performance characteristics of the steering system to those of the emergency system, which is switched on upon conclusion of the transitional phase. Thus, at the transition from the normal operating system to the emergency operating system, the driver is given time to become accustomed to the other steering performance.

Abstract: A method and apparatus for long vehicles to make sharp turns on city streets without running up on the curb. The back wheels of the vehicle are steered with the aid of a guide control wheel so that when the semi or truck is making a sharp turn, the rear wheels continue straight down the street to the intersection and then turn, even though the semi and the front of the trailer have already turned in a normal manner.

Abstract: A latching mechanism for receiving a boat bow U-bolt includes a frame member with a receiving channel for receipt of the U-bolt. A pair of spring-biased latching members are attached to the frame member and arranged in a normally-closed condition and therein narrow the width of the receiving channel at an entrance location. The latching members are pivotally moveable to an open condition by the action of the U-bolt pushing against the latching members until the U-bolt enters the receiving channel. A release slide is included as part of the latching mechanism to allow the U-bolt to be released. The release slide is spring biased for movement from a load-launch orientation to a stowed orientation. The latching mechanism is designed to attach to a winch stand and includes two separate mounting connections for this purpose.

Abstract: This hauling tarpaulin can be deployed, loaded with refuse, moved and unloaded by a single person. A stored tarpaulin rolled about a mandrel is easily unrolled and filled with lawn refuse. The mandrel holds the tarpaulin flat on the ground despite wind. When the hauling tarpaulin is filled with refuse, the hauling line is pulled, causing the mandrel to rise up on its legs, and the sides to rise, forming a boat-shaped structure which engulfs the refuse. The hauling tarpaulin then is pulled by the hauling line to the refuse collecting point. At the collecting point the tarpaulin is restored to its flat form and the waste material unloaded.

Abstract: A torque-based method to steer a vehicle equipped with a steer by wire system begins when a driver applies torque to a steering wheel so as to change the direction in which the vehicle travels. Two sensors, a steering wheel angle sensor and a steering wheel torque sensor then generate an angle signal and a torque signal, respectively. In the unlikely event the vehicle steering system is malfunctioning, the steering wheel torque sensor will still generate a torque signal. This torque signal is used in place of the angle signal to generate the reference signal. Once the reference signal is generated, then it can be used to generate the road wheel angle signal, which is in turn used to position the road wheels accordingly.

Abstract: A socketless fitting for releasable connection of a pressurized line. The fitting has a housing body with a receiving opening to insert one end of the line, and an inner sleeve attached in the housing body in an arrangement that extends coaxially within the receiving opening for engagement into the inserted line end. The inner sleeve is fastened in the housing body media-tight around the periphery by a connector and preferably engages in the line media-tight around the periphery. A clamping element axially movable in the receiving opening cooperates with an inner surface of the housing body to secure the line end onto the inner sleeve. Media-tight outward sealing is accomplished by sealing engagement of the essentially rigidly secured inner sleeve in the line, because the inner sleeve itself is also tightly joined to the housing body.

Abstract: A land vehicle, such as a snowmobile, comprises a frame with an engine mounted to the frame. The frame is supported by at least one steerable member. The steerable member is controlled by a rider with a steering handle. The engine comprises a decompression mechanism to lower the compression ratio during starting, for instance. The decompression mechanism is actuated by an actuator mounted outside of an engine compartment in which the engine is mounted. The actuator can be a steering handle mounted lever. The decompression mechanism can be mounted on a cylinder head of the engine. In one arrangement that allows the mechanism to control compression in multiple cylinders, the mechanism can be mounted between adjacent exhaust ports of adjacent cylinders.
