An instrument for surgical purposes has two relatively movable working parts and two relatively pivotable jaws interconnected in such a way that when they are opened, the two working parts are pushed together, whereby one of the two jaws has a shaft for the pivotable fitting of the other. The shaft is provided with regions of differing diameter and can be axially moved in such a way that selectively a larger or smaller-diameter region is effective in the region of the other jaw, which has a slot...

A torque limiting coupling (5) for a driveline driving agricultural implements has driving members (16) which, with reference to the rotational axis (15), are displaced inwardly from a torque transmitting position into a disconnected position. If overloading occurs, the driving members (16) are automatically moved to re-engage a groove (45) in the coupling sleeve (42) if the positions of the driving members (16) and the torque transmitting faces correspond to one another. Also, a switching ring ...

An inking pump for an offset printing press has a cylinder defining a bore in which a plunger is received for both rotation and linear reciprocation, creating a first and a second opposed fluid chamber. The cylinder has formed therein a first and a second suction port with a spacing therebetween axially of the bore, and, angularly spaced 180 degrees from the suction ports, a first and a second discharge port with an axial spacing therebetween. The plunger has formed in its surface a first recess...

The object of this invention is to provide a block set for educational purposes. The block set features that a plurality of block units of the same color are integrated so as to build a block bar, and two or more block bars respectively of different colors are crosswisely combined to build a block bar combination, and two or more block bar combinations interconnect one another to thereby build a variety of structures having two or more colors, wherein the block bars of the same color are symmetr...

The invention concerns an instrument for medical purposes, comprising a housing (8) which can be introduced into an animal or human body, a movably mounted electromagnetic or acoustic transducer unit (7) arranged in the housing (8), preferably in the distal end thereof, for producing electromagnetic or acoustic waves, in particular ultrasonic waves, and a drive (1, 2) for driving the transducer unit (7), wherein the transducer unit (7) is connected to at least one first contact element (9a) and ...

The present invention relates to a cutting tool with increased tool life when machining grey cast iron. The tool comprises a solid CBN-containing body containing more than 60 vol % CBN and a coating. The coating consists of at least one layer of metal nitride, carbonitride or carbide with the metal elements selected from at least one of Ti, Nb, Hf, V, Ta, Mo, Zr, Cr, W and Al, with a total thickness of 2-7 .mu.m and 2-8 .mu.m of .alpha.- and/or .kappa.-Al.sub.2 O.sub.3. The coating is a CVD coat...

A multi-purposes warning device includes a battery container, a tube threadedly engaged to an end of the battery container and a flash bulb disposed in the tube, a bracket pivotally engaged to the tube and a flashlight head pivotally engaged to the bracket, a socket slidably mounted to the battery container and the tube, three feet each has an end pivotally connected to the socket and a stick respectively and pivotally connected between the inner side of each of the feet and an outer periphery o...

Agents containing magnetic particles are suitable for use in enhancing images in diagnostic procedures, e.g., via x-ray, ultrasound or especially NMR. Preferred particles are based on metals, e.g., iron, cobalt or nickel, double metal oxides/hydroxides or complexes thereof.

The syringe for medicinal purposes features a syringe barrel (1), one end of which is formed as an adapter (2) for a cannula or a closure (3), e.g., in the form of a tip cap, and of a plunger (4), arranged within the syringe barrel (1), and movable by a piston rod (5). At the end of the syringe barrel (1) facing away from the adapter (2), a plunger brake (6) is arranged, which is formed by a rest piece surrounding the syringe barrel (1) and connected removably to it. The rest piece has a project...

The invention relates to a profiled sheet for building purposes, especially roofing and facade sheet, the sheet having a normal profiling and having in addition, at least in certain sections, a corrugated microprofiling deviating from the normal profiling. The microprofiling exhibits flattened and/or pressed-in areas in its crest, valley and/or flank sections resulting in that the thickness of the profiled sheet varies in a direction transversely of the longitudinal direction of the microprofili...
