Abstract: The clamping device (10) has two single-sided lever arms (21, 22) which are rotatably mounted together on a pivot pin (17). The lever arms (21, 22) are coupled to one another at a fixed angle by a gear (18) likewise mounted on the pivot pin (17). For this purpose, this gear (18), with all its teeth, meshes jointly and in a flush manner with two internally toothed rims, each of which is a component of one of the lever arms (21, 22). To adjust the angular position between the two lever arms (21, 22), the gear (18) can be laterally displaced by pressure on the pivot pin (17) in such a way that it only meshes with one of the internally toothed rims. The two lever arms (21, 22) are thereby disengaged and can be rotated relative to one another. A spring presses the gear (18) back into its original position as soon as the pressure on the pin (17) ceases. The clamping device (10) is actuated by a hydraulic cylinder (25) which is counteracted by the force of a restoring spring (28). The clamping device (10) is intended for machine tools which have a machine table with T-slots. <IMAGE>

Filed: 1990-08-10
Abstract: An in vitro method and probe for determining the presence of the ring shaped particle (RSP) tumor marker and for detecting the presence of malignancy in humans and animals comprises capturing the marker out of a biological fluid containing cancerous cells onto a substrate and detecting the presence of the RSP tumor marker on the substrate as an indicator of the presence of the malignancy. One preferred method involves using an anti-RSP antibody (rspAb) selected from one or more of the monoclonal, polyclonal and affinity purified antibodies to capture the tumor marker from a sample of a biological fluid such as blood serum, sputum, urine, irrigation fluids, etc.. The tumor marker is captured onto a substrate with an rspAb and its presence on the substrate is detected using common detection systems, such as color development techniques. In one preferred form, the tumor marker is detected on the substrate by reaction with a tRNA-photobiotin-streptavidin-alkaline phosphatase probe. Another preferred method involves using a transfer ribonucleic acid (tRNA) probe which is specific to the aminoacyl transfer RNA synthetase reactive site on the marker and detecting the presence of the RSP by color development techniques using a tRNA-photobiotin-streptavidin-alkaline phosphatase probe.

Abstract: The invention provides a method and apparatus for equalizing the temperature of molten glass (2) over the cross-section of a stream thereof advancing through a refractory forehearth from a glass furnace to a glass working machine. To this end, cooling air is blown downwardly to strike the mid-line of the stream, and is then evacuated upwardly from locations on either side of the mid-line, in such manner that substantial side regions of the stream surface are preserved from cooling contact with the cooling air. Apparatus for this purpose comprises refractory blocks (4a, 4b) which can be assembled to form a forehearth superstructure or roof, the blocks having hollow formations which unite on assembly thereof to form feed (11) and return (12, 13) channels for the cooling air, as well as inlet (8) and exhaust (9, 10) ducts for directing it at the molten glass and recovering it thereafter.

Abstract: The crude Ti particles prepared by molten salt electrolysis or Iodide methcd are classified into each particle diameter according to contents of impurities, and the crude Ti particles having a desired particle diameter are selected from the crude Ti particles classified depending on each particle diameter. Otherwise, the crude Ti particles are acid-treated. Then they are electron-beam-melted. Through the above production process, there is prepared a highly purified Ti material having an oxygen content of not more than 350 ppm, Fe, Ni and Cr contents of not more than 15 ppm each, Na and K contents of not more than 0.5 ppm each, a reduction of area as a material characteristic of not less than 70%, and a thermal conductivity of not less than 16 W/m K. In short, the highly purified Ti material satisfying high purity, good processability and good thermal conductivity can be obtained. A film having more uniform thickness of film and inside structure can be obtained from a sputtering target prepared using the above highly purified Ti material.
