Abstract: A connecting part (10) for making an electrically conducting connection consists of a plate-like base (11) and of retaining limbs (12, 13) which are chamfered and originate from mutually opposite sides of the base, at least one of which is fitted with lateral teeth and can be inserted in a self-locking manner in a slot-like recess (21, 22) of a dielectric material supporting part (18) holding the connecting part. The retaining limb (12, 13) of the connecting part, provided with lateral teeth (15, 16) is in this case initially chamfered by considerably less than 90 angular degrees from the plane of the base (11, 31) and is then swivelled into its slot-shaped recess (21, 22) - deforming the chamfered point of the retaining limb - for permanent attachment of the connecting part to the dielectric material supporting part, its teeth clawing into lateral walls (25, 26) of the slot-shaped recess - crushing or slightly damaging these walls. As a result of the (at least one) retaining limb swivelling rather than longitudinally, axially sliding into the slot-shaped recess, better retention of the connecting part to the dielectric material supporting part is achieved and, at the same time, surface damage to the side walls of the recess is virtually avoided. <IMAGE>

Abstract: A rotary piston engine with a rotor for circular and axial stroke movements is further developed by means of a positive control in such a way that the rotor and the cylinder head shape alone define the working chambers, no additional slide valves being necessary. This is achieved by means of a gear with a bevel gear, in which bevel gear wheels engage which are fixed to driving cogs of a drive shaft and which have an eccentric crankpin on which the connecting rods of the rotary piston are supported. In this way the rotary movement of the piston is converted in such a way that the piston moves precisely along the indentations and projections of the working chamber. <IMAGE>

Abstract: The device for generating pressure pulses in a drilling fluid flowing down through a drill-pipe string (1) comprises a valve (V) arranged in the drill-pipe string (1) and having a tubular outer part (3) supported in a fixed position, a tubular main valve body (4) which can be displaced from a bottom initial position against the flow direction (2) of the drilling fluid into a top end operating position, a fixed, tubular support body (5) arranged coaxially in the main valve body (4), and an auxiliary valve (13, 14) which can be actuated by means of a drive (15). The outer part (3) and the main valve body (4) define between them a restriction section (29) with a cross-section of flow which can be varied as a function of the position of the main valve body (4), and the main valve body (4) and the support body (5) surround an inner flow passage (21, 12, 10) whose outlet opening (13) can be cleared and closed by means of the main valve body (4). The sum of the hydraulic forces, directed downwards and exerted by the drilling fluid on the main valve body (4) located in its initial position when auxiliary valve (13, 14) is open, and the gravitational forces exceeds that of the hydraulic forces directed upwards, and this force relationship is reversed by closing the auxiliary valve (13, 14). Here, in the end operating position of the main valve body (4), the sum of all forces acting on the main valve body (4) is zero, and the main valve body (4) is suspended free of striking in the drilling fluid.

Abstract: A track search circuit includes a command decoder (4) which decodes command data sent by a microcomputer and stored in a command register (1) and outputs signals commanding a track jump and commanding count of a counter (5) which counts a tracking error signal. Time difference between a present A-time and a target A-time is calculated such that an optical pick-up can be moved toward a target position by utilizing the track jump of 4 n . When a counted value of the counter reaches a predetermined value, the A-time is renewed such that the time difference can be reduced by addition or subtraction suitable time data to or from the A-time. If the renewed A-time becomes within 1 minutes with respect to the target A-time in repeating such a track jump in accordance with the renewed A-­time, the optical pick-up is stopped to move, and the A-time is read to jump the optical pick-up again to catch the target position.
