Abstract: A method is provided for producing large cubic boron nitride crystals having the size of 0,1 carat or larger. The method involves providing a reaction vessel which contains CBN seed material, a CBN source separated from the seed material by a mass of solvent/catalyst for CBN synthesis which is capable of melting under CBN synthesis conditions, the separation of seed material and source material being such that under the operating conditions of CBN synthesis a temperature gadient is created between the seed material and the source material with the seed material being located at a point near the minimum value of temperature of the temperature gradient and the source material being located at a point near the maximum value of temperature of the temperature gradient, placing that reaction vessel in the reaction zone of a high temperature/high pressure apparatus and subjecting the contents of the reaction vessel to conditions of temperature and pressure in the CBN stable region of the boron nitride phase diagram for a period of at least several hours.

Abstract: A power supply for helix and collector electrodes of a traveling wave tube is driven by an AC power source having a frequency of at least 500 KHz. The helix supply includes plural, stacked voltage doubler AC to DC modules responsive to the 500 KHz source. The collector supply includes plural AC to DC modules, each having a diode full wave rectifier bridge, connected in stacked relation. Each of the modules includes a transformer with a ferrite, toroidal core dimensioned so that it is not driven into saturation by the 500 KHz source. Each module also includes inexpensive, signal switching diodes having a recovery time of approximately 4 nanoseconds. The ratio of the collector to helix DC voltages is maintained constant by threading a common lead through the apertures of the toroidal cores of the helix and collector modules. A separate common lead threaded through the apertures of the toroidal cores in the collector modules is connected directly to the 500 KHz power source. A feedback circuit responsive to the helix-cathode voltage of the TWT controls the helix power supply voltage precisely.

Abstract: A piston (8) slidably inserted into a cylinder (7) is reciprocatably moved by fluid pressure such as pneumatic pressure and hydraulic oil and a spring (11) is used to move the piston upwardly. A spool-shaped pilot valve element (46) is provided to allow a supply-discharge valve disc (30) to take supply and discharge positions (X and Y), thus fluid pressure being supplied to and discharged from the cylinder. When the supply-discharge valve disc is actuated to take the supply position from the discharge position, the actuated force becomes stronger while the supply-discharge valve disc is in operation. When the supply-discharge valve disc is actuated to take the discharge position from the supply position, the back pressure resistance applied to the supply-discharge valve disc becomes weaker while the supply-discharge valve disc is in operation.

Abstract: A diagnostic test device is provided including a plate having at least one well, preferably a plurality of wells, each with an open bottom across which a composite membrane comprising three layers is placed, with a hydrophobic, liquid-tight seal provided at the periphery of each well. The composite membrane from the top or upstream side to the bottom or downstream side, in sequence, includes a first reaction or filtration layer formed from a thin, liquophilic, microporous membrane, a second or sealing layer, preferably a hydrophobic material in sheet or fiber form, such as nonwoven polypropylene fibers, and a liquophobic, preferably hydrophobic, barrier layer having one or more apertures which allows liquid to exit the well while eliminating lateral migration of a pendant liquid drop. The liquophobic seal provided by the liquophobic sealing layer eliminates "cross-talk" by lateral diffusion or wicking.

Abstract: The conventional dispenser, designed in "pistol form", for twin cartridges (40) with a feed piston (42) has a pressure-activated cylinder/piston unit (1) with plungers (7) extending from the piston (5, 6) and intended for the advance of the feed piston. The problem is that, during the piston advance, the reaction forces acting on the two plungers (7) from the feed pistons (42) can differ greatly (different viscosities of the substances contained in the two cartridge cylinders 41 and/or different cross-sections of the cartridge cylinders 41). To prevent the piston (5, 6) from "tilting" or jamming, according to the invention there is in the cylinder space (14, 15) a rigid longitudinal guide (10) between the two cylinder bottoms (2, 4), on which the piston is supported slidably by means of an elongate guide bore (9). The longitudinal guide (10) can at the same time stiffen the cylinder (2, 3, 4) and, furthermore, guide the pressure medium into the pressure space (15) behind the piston (5, 6) via a longitudinal channel (20). In connection with this, a rapid venting (21 - 24) for the pressure space (15) and control means (31, 32) for the return of the piston unit (5, 6) together with plungers (7) to the initial position are described. Moreover, restoring means (38, 39) for the piston to relieve the plungers after each advance step and indicator members (60, 61) for the cartridge filling level are disclosed.

Abstract: Bei Vorrichtungen, bei denen mindestens ein umlaufendes Preßband an die Werkstoffbahn von einem Druckmittel anpreßbar ist, das in ein mittels eines Dichtungsrahmens abgedichtetes Druckkissen eingeleitet wird, treten zwischen dem rechteckförmigen Dichtungsrahmen und dem Preßband Undichtigkeiten im Bereich der Ablaufseite des Produktes auf. Diese sind darauf zurückzuführen, daß das Produkt der Vorrichtung in hartem Zustand zugeführt, unter dem Einfluß von Wärme in einen weichen Zustand übergeführt wird, insbesondere im Längsrandbereich seine Form ändert und unter Abkühlung abbindet. Die Aufgabe besteht darin, die Vorrichtung so zu gestalten, daß durch das Druckkissen der volle Arbeitsdruck dem Produkt aufgegeben wird und die Undichtigkeiten zwischen dem Druckkissen und dem zugeordneten Preßband durch Verformung des Produktes vermieden werden. Der erfindungsgemäße Dichtungsrahmen (1) weist im Grundriß an der Zuführseite der Werkstoffbahn (8) eine größere Breite als an der Ablaufseite der Werkstoffbahn auf.

The plate is then mounted in a lithographic press for lithographic printing. As an alternative, the ink jet printhead may be mounted in a lithographic press for imaging a lithographic plate mounted in the lithographic press or for spraying ink directly onto the plate cylinder of the press. A succession of lithographic plates may be provided around the plate cylinder of the lithographic press and each plate discarded after use, leaving a clean plate on the plate cylinder.
