When used as holder for tools for partial machining tasks or as clamping means for exchangeable tools, the clamping block for clamping workpieces or tools make it possible to carry out a rapid and precisely reproducible exchange of the object (7) to be clamped. The clamping block having a block base (1) and a clamping jaw (5) which can be displaced relative thereto comprises a fixed clamping jaw (3) and means (4, 4.2) for the at least approximately parallel guidance of the moveable clamping jaw ...

The invention relates to a flushing block for introducing gaseous and/or solid reagents and additives into a metallurgical melting vessel, which is connectable at one end to a gas pipe and at least to a drive means and at its other end has at least one outlet opening extending from its circumferential surface, said opening terminating in at least one gas channel which can be connected to the gas pipe.

An internal combustion engine includes a cylinder block, and a plurality of main bearing caps secured to the cylinder block at a predetermined portion. A flange integral with the cylinder block has first and second end walls extending from the cylinder block and spaced from each other, and a peripheral wall which interconnects the first and second end walls. The first, second and peripheral walls cooperate with the predetermined portion of the cylinder block to define a chamber. The peripheral w...

A block structure adaptable for use as a toy and including a plurality of blocks secured in side-by-side relationship to a sheet of flexible material. The geometric attitude of the blocks with respect to each other may be changed by bending the sheet along the junctures between the blocks. The blocks may be temporarily locked in a particular geometric configuration by wedges insertable into such junctures and engageable with the facing sides of adjacent blocks.

A sanding block for a continuous loop type sanding belt, comprising a basic rectangular block with an end block element which is longitudinally adjustable by means of screw jack elements to clamp tightly inside the sanding belt. The screw jack elements are readily accessible and are operable without tools.

A terminal block for receiving and electrically interconnecting a plurality of pin contacts. The pin contacts are inserted into bores formed in the body of the terminal block and the forward or nose portions thereof are telescopically received in mating socket contacts securely disposed within the bores. Also disposed within each bore is a sheet-form member rolled into a generally tubular configuration and having a collet portion which retains its respective pin contact in its corresponding bore...

A valve block particularly for a medical or surgical ventilating machine allows easy cleaning and sterilization. The valve block has several nonreturn valves whose valve members are coplanar. These valves separate chambers in the block arranged to overlap each other in a chosen configuration to facilitate a desired pattern of interconnection.

A boat block for supporting the sloping sides of a boat which can be used in any one of at least two positions to change the height of the boat hull contacting member above the keel-supporting block so that the boat block can support a variety of boat hulls of various shapes.

A block device having transparent outer walls through which there are visible inner walls within the block carrying art work, with the inner walls within the block carrying art work, with the inner walls being centrally bowed inwardly away from the transparent outer walls in a manner giving a unique somewhat three-dimensional appearance to the art work.

A tool block is provided with a cutting insert holder (12), provided with a cutting insert (14), and a clamping device comprising a pivotally arranged lever (20), one end of which acts on the cutting insert holder (12) while the other end of which cooperates with a spring loaded device (21).
