Title: Method and apparatus for determining  ultrafiltration during dialysis
Inventor: GOLDHABER RICHARD P
IPC: B01D61/30
Filed: 1978-03-14
Granted: 1982-06-15
Abstract: ABSTRACT OF THE DISCLOSURE           The ultrafiltration provided by an operating dialyzer is measured by sealing a portion of the dialysis solution flow path, including the dialysis unit, to pre-vent solution flow into or out of the portion, while effecting flow of the liquid to be dialyzed through a se-cond flow path in the dialysis unit.  Simultaneously, the dialysis solution flow path is in communication with a solution receptacle, at least part of which is vertically elevated over the dialysis unit.  Accordingly, dialysis solution flows into the receptacle over a period of time under these conditions in a manner corresponding to the ultrafiltration of the dialysis system.

Abstract: ABSTRACT:          A power-supply device for a microchannel tube comprising a sercen, a microchannel plate and a photocathode, which device comprises a first oscillator which via a first voltage multiplier supplies the screen voltage. This device energizes the plate via a second multiplier which is eon-nected to the first oscillator via a transformer, and a third multiplier which is connected in series with the second multiplier and is connected to a second oscillator by the transformer. The photocathode is driven by a voltage chopper which receives its power from the second oscillator, said second oscillator and consequently the chopper, being controlled by the average screen current. In another version of the invention the chopper receives its power from the first oscillator via a  voltage multiplier.           Used for night-vision applications.

Abstract: Abstract of the disclosure: Special cyclic enamides I are prepared by splitting off alcohols catalytically from the corresponding cyclic amides II, in the presence of at least one tetraalkylammonium and/or alkali metal salt of tetrafluoroboric acid and/or of hexafluorophos-phoric acid as the catalyst, at a temperature of from about 120 to 250°C, distilling off the detached alcohol and iso-lating the formed enamide I in known manner.  Those cyclic amides II are particularly preferred starting compounds, which have been obtained by anodic alkoxylation of corre-sponding cyclic N-compounds III in an alcohol in the presen-ce of supporting electrolytes which are identical with the catalysts subsequently used for splitting off the alcohol, and by distilling off the alcohol from the reaction batch. The enamides I are valuable starting products and inter-mediates for various syntheses, for example of prosta-glandins and of other pharmaceuticals.

Abstract: Abstract of the Invention An arctic vehicle is provided for the rapid transport of goods, machinery, and personnel over ice, snow and frozen ground surfaces.      The vehicle is supported partially while at rest and/or under way by a cushion of air which is entrained by a system of seals.  Seals along the sides terminate in runners for guiding and partially supporting the vehicles.  A cutter system is deployed in front of each runner to form smooth running tracks or furrows over ice, snow, and frozen ground surfaces.  A transverse cutter may be deployed in front of the forward transverse seal for removing major ice protrusions between the runners, to reduce seal leakage and wear, and improve ride characteristics.  The cut tracks, in addition to providing smooth transit, engage the runners and side seals to prevent lateral shifting of the vehicle by the action of crosswinds and sideslopes.     The vehicle may be self-propelled or towed.  Through the use of the air cushion, frictional resistance to movement is substantially reduced, requiring correspondingly less motive power or towing force.  Also the load of the vehicle is distributed over a larger area.     The vehicle may be part of a train system pulling similar cars whose running friction is reduced by a common air bubble formed between longitudinal seals of the driving vehicle and drawn cars and end seals.  In the alternative, the driving vehicle and each drawn car may be provided with an air pressure seal system to provide individually contained air bubbles.
