Abstract: The invention relates to a device for generating and/or arranging sequences of a fluid sample in a carrier fluid. The invention comprises a microchannel having an inlet, an outlet and a nozzle opening therebetween leading into the microchannel. The invention further relates to a delivery unit, which pumps in the carrier fluid using a feed volume flow and suctions off the carrier fluid using a discharge volume flow. In a sample container, the nozzle opening is in contact with the fluid sample. By means of a control unit, the ratio between feed volume flow and discharge volume flow is varied. The cross-section of the nozzle opening is selected such that no carrier medium exits from the nozzle opening when the feed volume flow equals the discharge volume flow and that a fluid sample enters the nozzle opening when the discharge volume flow is greater than the feed volume flow. The invention further relates to a method for generating and/or arranging sequences of a fluid sample in a carrier fluid.

The masonry structures of the invention include vertical bores disposed along their lengths, and include tensioned cables which extend through a first vertical bore, are spirally wound about the re-bar, and also extend through a second vertical bore such that the end portions are rigidly anchored in position near the top course of masonry units used in constructing the structures, and wherein the tensioned cables are under a relatively high mechanical tension. By staggering a plurality of tensioning cables, structures comprising a plurality of masonry units of enhanced structural stability over structures of prior art are provided.

Abstract: A casting system includes a filtration assembly including a filter vessel housing spaced filters pre-heated to a temperature approximating a pouring temperature of molten material to be filtered to prevent breakage of the filter due to thermal shock from contact with the molten material. Preferably, an induction coil is used to inductively heat a susceptor adjacent the filter vessel or inductively heat filters which themselves serve as susceptors. Typically, the filter vessel is disposed below a pouring vessel and above a mold, pour cup and any sprue system used and is heated independently from the same. The filters are heated during pouring to facilitate flow of the molten material therethrough whereby very fine filters may be used. Spacing of the filters enhances flow control and allows a head of molten material to form whereby dross floats to the top of the head to prevent its entry into the mold.

Abstract: A process for the production of valve seat rings by powder metallurgy wherein molybdenum disulfide in the range of about 0.5% to 1.5% by weight is added to a powder mixture containing 0.8% to 1.5% by weight graphite, 1.0% to 4% by weight lead, 0.5% to 5% by weight nickel, 1.2% to 1.8% by weight molybdenum, 9.6% to 14.4% by weight cobalt, and the remainder iron. The resulting powder mixture is pressed into valve seat rings at a pressing force between 40 and 60 and preferably 50 KN/cm.sup.2. The rings are then sintered in a neutral atmosphere at a temperature of 1100.degree. C. to 1200.degree. C., finally compressed at a pressing force above 120 KN/cm.sup.2 and heat-treated if required. The resulting valve seat rings have greatly improved wear properties when used in internal combustion engines using lead-free gasoline.
