Abstract: A cover plate for use in lyophilization processes is provided. The cover plate includes a base portion and a plurality of protuberances which project from the base portion. The protuberances are adapted to fit in one or more delivery containers, such as syringe barrels. The cover plate permits the escape of vapor from the one or more delivery containers during a lyophilization process. In addition, the cover plate prevents the escape of lyophilizate from the one or more delivery containers during a lyophilization process. Vent features provided to provide enhanced and preferred venting operations during lyophilization processes.

Abstract: There is provided a method for determining Total Acid Number (TAN) in a fluid fossil fuel, such as a crude oil, comprising: separating said fluid fossil fuel by liquid chromatography into a plurality of fractions, comprising at least one acidic fraction; determining boiling point distribution of said crude oil, of said acidic fraction, and of said polyacidic fraction by simulated distillation (SD); and correlating said boiling point distributions to acid molecular weights to determine the TAN.

Abstract: A turbomachine outer case includes a pair of outer case sections, each provided with attachment flanges for securing said pair of outer case sections about an internal rotor structure, the pair of outer case sections constructed of a cement composite material. The outer case sections may be lined with a relatively thin metal alloy.

Abstract: The invention relates to a bellows to seal a valve rod passage in a lifting valve, specifically formed as an expansion bellows or corrugated tube, which ensures a reliable, hygienically proper and durable static sealing of the connecting flange of a closing-member unit in the box of the lifting valve under the occurring forces at an adequately long service life.

Abstract: The invention relates to a device for the drive system for double seat valves comprising two individually movable closure members which, in addition to the open position, can each be individually moved into a partial open position. The object of the invention is to construct a device which is easy to assemble and is space-saving and which should be able to provide externally adjustable, partial lift stops for both closure members. Said object is attained in that a piston (107) of a first individual adjustment device (1b) for the partial open position (T1) of the independently driven closure member (4) is displaceably arranged, to form a seal, externally in a drive housing (100) of the drive device (1), and a piston (108) of a second individual adjustment device (1c) for the partial open position (T2) of the dependently driven closure member (5) is displaceably arranged, to form a seal, externally in a cylindrical recess (107a) of the piston (107), which recess faces a main adjustment device (1a).

Abstract: The invention concerns a cleanable scraper station which is designed as a dispatch/receive station (1;1*) and through which the product or cleaning agent flows. The aim of the invention is to improve the cleanability of the scraper station compared with prior art devices, as measured by increased throughput, and in particular to ensure through cleaning of the entire scraper surface. This is achieved by virtue of the fact that the scraper (9) is positioned with play in all directions when in the through-flow position (II,II*) by means of a controllable second stop (6a;6a*) acting in conjunction with a displaceable first stop (5a,5a*) or by means of the controllable second stop (6a;6a*) acting in conjunction with a coupling cage (50;50*) connected to the displaceable first stop (5a;5a*) and in which the scraper (9) is positively locked, or only by means of the coupling cage (50;50*) connected to the displaceable first stop (5a;5*) and in which the scraper (9) is positively locked.

Abstract: A method of inhibiting the corrosion of iron-based metallurgies in contact with cooling water systems under severe corrosion inducing conditions comprising adding to said cooling water an aqueous combination of an alcohol, an acid, a fatty imidazoline, and an ethoxylated fatty diamine.
