Abstract: A control apparatus for a hydrostatic auxiliary power steering arrangement, in particular for vehicles, has a metering motor (10) and two coaxial rotary slide valves (16, 17) forming between them a directional valve (14). The directional valve (14) is opened by rotating the inner rotary slide valve (17) by means of a steering element (57), so that fluid under pressure is allowed to pass through the metering motor (10) to a steering motor (8) and the metering motor (10) adjusts the outer rotary slide valve (16) in dependence on the amount of fluid flowing through the inner rotary slide valve (17). To avoid abrupt changes in the rotational speed of the inner rotary slide valve, and therefore to prevent acceleration forces that are too high being exerted on the steered item and possibly on the person controlling the steering, the inner rotary slide valve (17) is connected to a damping arrangement (70) counteracting its rotational movement.

Abstract: A unity power factor power supply for an electric motor. A switch-mode circuit is employed which, in a first mode, transfers power from AC main to a constant voltage DC bus. In a second mode, power generated on the DC bus is fed back to the main power supply. The circuit of the invention automatically maintains the DC bus voltage constant and sets an adequate operation mode by processing the DC bus voltage signal. In both operation modes, the unity power factor and sinusoidal waveform of the AC main side are maintained.

Abstract: An analysis method is disclosed, in which several samples are passed in succession through a reaction channel (16) to a detector (17), and at least one reagent is introduced into the reaction channel (16) for reaction with the samples. An apparatus for implementing the method is also disclosed. Using the method and the apparatus, it is intended to specify an analysis method more capable of coping with different flow characteristics of the samples in fluid form. For that purpose, each sample and its associated reagent is introduced in a controlled manner into the reaction channel so that they form a block, along the length of which the local volume ratio between sample and reagent, averaged over a segment of predetermined length, is substantially constant, the length of the segment being substantially shorter than half the length of the block.

Abstract: In a radiator valve a second throttle point which is formed by a gap (119) between an annular face (114) surrounding the valve seat and the end face of an insert (113) is located downstream of a first throttle point between the valve seat (108) and the closure member (109). The gap (119) is axially offset with respect to the valve seat (108). In particular, the valve seat (108) projects beyong the annular face (114). In this manner, valve noise can be considerably reduced.

Abstract: A hydraulic axial piston motor (1) is disclosed, having a cylinder drum (4) which is connected, so that it is non-movable axially, to a shaft (3) and so that they rotate together, and which has at least one cylinder (5), for each cylinder a piston (6) arranged in the cylinder, which piston bears at its end projecting from the cylinder drum (4) against a swash plate (8) via the intermediary of a slider shoe (7), a pressure-applying arrangement (9) for holding at least one slider shoe (7) against the swash plate and a control plate (12) with control kidneys. It is desirable for such a motor to be reliably operable even when the shaft is provided with axial play. Leakages in particular are to be avoided. For that purpose, the pressure-applying device (9) is mounted so as to be axially movable relative to the cylinder drum (4). A pressure plate (13) that is axially movable relative to the cylinder drum (4) is arranged between the control plate (12) and the cylinder drum (4), this pressure plate having for each cylinder a through-opening (14) which is connected in a fluid-tight manner to the cylinder (5). Furthermore, between the pressure-applying device (9) and the presssure plate (13) there is provided an expanding device (18) which acts on the pressure-applying device (9) and the pressure plate (13) with oppositely directed forces.
