Abstract: A method for permanently fastening a cam on a cam carrier may involve positioning the cam on the cam carrier in a predefined axial and angular position. By way of the positioning, an end face of the cam carrier is aligned with an end face of the cam. The method may also involve positioning a cam segment formed by the cam carrier and the cam in an assembly device. The cam carrier may then be deformed such that the cam is secured at least in a form-fitting or force-fitting manner against movement in an axial direction on the cam carrier. A deformation tool of the assembly device may be advanced in an axial direction onto the end face of the cam carrier, and the cam carrier may be deformed such that material of the cam carrier is forced outward in a radial direction against the cam.

Abstract: A camshaft arrangement for a motor vehicle engine has a hollow outer shaft and an inner shaft supporting inner shaft cams. The inner shaft cams are non-rotatably attached to the inner shaft by at least one connection element that protrudes with clearance through an aperture in the outer shaft and is attached to the respective inner shaft cam which is rotatably mounted on the outer shaft. When inserted into a receiver in the inner shaft, a portion of the connection element protrudes out of the receiver, and the protruding portion is at least partially inserted into an aperture located at the joint diameter of the inner shaft cam. This aperture is open at least towards an end face of the inner shaft cam. The protruding portion has at least two opposite-lying side surfaces lying with an interference fit against corresponding inner surfaces of the aperture of the inner shaft cam.

Abstract: An electromotor, in particular a brushless pump motor having a motor housing, a circuit board, flexible electric lines that are guided in a passage through the motor housing and connected to the circuit board by way of connections, with hollow spaces in the motor housing being partially or completely filled with a hardenable plastic material. The flexible electric lines run between their connections to the circuit board and the passage of the motor housing with a total change in direction amounting to at least 40° and are arranged in at least one of the hollow spaces of the motor housing that is filled with hardenable plastic material, such as polyurethane foam. The flexible electrical lines are essentially completely surrounded by the hardenable plastic material at least in the regions of the changes in direction in the progression of the electric lines. Alternative methods of assembling the motor are provided.

Abstract: Inherent clock information included in a digital signal of the type in which binary information is represented by signal level transistions which are present on a periodic basis, such as a signal level transistion at a mid-location of a bit interval, is recovered by generating a pulse at each signal level transition, delaying that pulse by a half bit interval and by a full bit interval, respectively, and summing the generated, the half bit delayed and the full bit delayed pulses to recover the clock information. The recovered clock is used to write each binary level included in the received digital signal into a memory from which each stored binary level is read at a reference clock rate. Loss of synchronization between the received and read-out digital signals is detected by sensing a differential of predetermined magnitude in the write-in and read-out rates.
