Abstract: A valve is mounted in a first bore in a first separable section of a transmission to block or allow fluid flow through the first bore to a second bore in a second transmission section depending on whether the first and second sections are joined together or separated. A movable portion of the valve is responsive to an actuator during relative movement of the transmission sections to shift between fluid flow open and fluid flow closed positions. The valve can include a valve housing fixed in the first bore and a carrying plunger biased to the fluid blocking position and responsive to the actuator for movement to the fluid flow open position. The valve forms a fluid flow path between the first and second bores across the gap between the facing surfaces of the joined transmission sections.

Abstract: A series of gear train housings has different sizes. Each size includes a series of different housing types, which are suitable for at least two different gear train types of the following types: spur-gear gear trains, bevel-gear gear trains, flat gear trains, and worm gear trains. Each gear train housing has a housing opening on the drive side, which housing opening is surrounded by a drive flange for connecting a motor, an adapter plate, or an additional gear train. In at least two different sizes, the axes of bearing points designed to accommodate shaft bearings for toothed parts, said axes extending perpendicularly to the plane of the drive flange, lie inside a minimum inside diameter of the drive flange as viewed in a direction perpendicular to the plane of the drive flange for at least two different types of each of said sizes.

Abstract: A data buffer incorporated in the read return path between a processing pipeline and a frame buffer enables data reads from the buffer to be in a different order from data writes to the buffer. With this buffer, the frame buffer no longer is required to process read requests in any particular order and can be configured for improved processing speeds. The buffer includes a RAM to which data from the frame buffer is written according to a first order and from which data is read according to a second order. The buffer may be configured with multiple RAMs if the speed of data arriving from the frame buffer is greater than the write speed of the RAM.

Abstract: A speed measuring system comprising at least one stationary speed sensor (4) for detecting a speed of a measuring body (1) rotating relative to the speed sensor (4) wherein the measuring body (1) is provided, on its periphery, with electric or magnetic discontinuities. The speed sensor (4) situated at a defined distance from the measuring body (1), reacts to the discontinuities when the measuring body (1) is moved past the speed sensor (4). The speed measuring system has, in addition, one separate distance sensor (5) for determining an actual distance (LS) and an actual change in distance between the speed sensor (4) and the measuring body (1). In an evaluation device of the speed measuring system the speed of the measuring body (1) is formed from an actual output signal of the speed sensor (4) according to an actual output signal of the distance sensor (5).

Abstract: A two-piece housing is provided with several bores (3, 4) which extend through the two housing sections (1, 2). Each bore (3, 4) is concentrically surrounded by a centering in each housing section (1, 2), which is in the shape of an internal centering in one housing section and an external centering in the other housing section. These bores (3, 4) are manufactured in each housing section (1, 2) together with the respective concentrically surrounding centering and in one process step with a drilling tool which includes two cutters (8, 9, 10) adapted to the diameters of the bore and the centering respectively. Subsequently, the housing sections (1, 2) provided with the bores (3, 4) and centerings are assembled in such a way that the centerings fittingly interengage. (FIG.
