摘要： A power transmission device allowing axial displacement for use in drilling machines and the like comprises an element which is rotatable by means of a motor (2) by the intermediary of means engaging each other and having complementary internal and external grooves and ridges, and which is axially displaceable relative to a frame (1).
The novel features of the invention reside in that a first element (13) is hollow and provided with longitudinal internal grooves and ridges (15), that a second element (17) is provided only at a free end extending into the hollow element, with short external grooves and ridges (19), the first element (13) being radially non-displaceably mounted at both ends while the second element (17) is mounted by means of a single bearing at the frame (1).

摘要： The invention relates to an apparatus for portional ejection of lubricant for lubrication of railway rails, comprising a tank (1) for lubricant, a dosage pump (8) driven by an operating unit (9), a nozzle, and a control unit for actuation of the operating unit.
The novelty resides in that the operating unit (9) of the dosage pump (8) consists of an electromagnet (20) including a movable armature (22) the movement of which acts upon an ejector piston (17) in the dosage pump (8) and that a connecting means (18, 19, 28, 24, 30) is provided between the movable armature (22) of the electromagnet (20) and said ejector piston, said connecting means establishing a power-transmitting connection only after a predetermined distance of displacement of the armature (22).
