Title: Process for the enantioselective preparation of acyclic alpha-alkylated alpha-aminecarboxylic acids

Granted: 1987-04-09
Abstract: alpha -Alkylated, acyclic  alpha -aminocarboxylic acids of the formula   <IMAGE>   where * represents a center of asymmetry, R1 is a lower alkyl, allyl, benzyl or substituted benzyl group and R2 is a lower alkyl, methoxymethyl, lower alkylmercaptoethyl, phenyl, phenyl substituted with alkyl or alkoxy, benzyl, or benzyl substituted with alkyl, alkoxy or halo are produced by an enantio-selective plural step process from the corresponding  alpha -aminocarboxylic acid monomethyl or monoethyl amide. A particular advantage of the new process is that there can be produced from one educt-enantiomer, i.e. from an (S)- or an (R)- alpha -aminocarboxylic acid, selectively depending on the reaction conditions used the two enantiomeric forms of the desired  alpha -alkyl- alpha -aminocarboxylic acid.

Abstract: A fiber-optic transducer apparatus, and a related method of manufacturing it, for particular use in medical applications such as invasive blood pressure and body temperature measurement. The apparatus includes a catheter comprised of a sheath and an enclosed first set of optical fibers for transmitting a light beam to and from the remote end of the catheter, where a transducer modulates it in accordance with the variable to be measured, e.g., blood pressure. A photosensor located at the near end of the catheter measures the modulated intensity of the returned beam, to produce a corresponding measurement signal. The catheter is further comprised of a second set of optical fibers located within the sheath, for transmitting a reference light beam to and from the remote end of the catheter. A second photosensor measures the intensity of the returned reference light beam, to produce a correction signal indicative of variations in transmittance caused by bending of the catheter. It is presumed that the effects of such bending are the same for the second set of optical fibers as for the first set, so the apparatus adjusts the measurement signal in accordance with the correction signal, to produce an adjusted measurement signal that is substantially insensitive to the effects of such bending.

Title: Wet press for dewatering a web material
Inventor: DAHL HANS K DR-ING
IPC: D21F3/02
Filed: 1985-01-26
Granted: 1988-01-07
Abstract: In a wet press for dewatering a web of material, for instance a web of paper, a contact pressure device presses against a rotating roll and exerts a pressure which increases in the travel direction of the web of paper. For this purpose, several rows of contact pressure elements are arranged sequentially in the travel direction of the web of paper. In each row the contact pressure elements are arranged side by side transversely to the travel direction of the web of paper. In order to circumvent a differential dewatering at the location of the contact pressure elements and at the gaps between the contact pressure elements of a row, the contact pressure elements of successive rows are shifted or staggered in relation to one another transversely to the web of material such that they mutually overlap. This prevents the arisal of strips in the paper being processed.

Date Jul. 28, 1988.The reactor core of the plant has tubular vertically movable control rods moved by a pressurized flowing coolant. Each control rod so extends around a tubular guide rod which is immobile relatively to the reactor core as to leave a first annular gap between the control rod and the guide rod. The guide rod interior is operative as a first pressure chamber to which the pressurized coolant is supplied. The top end of each control rod is closed and has a vertical spindle which extends into the guide rod interior and co-operates with the guide rod to bound a second annular gap. At least one first restrictor is disposed in the first annular gap and at least one second restrictor is provided in the second annular gap. A second pressure chamber is present between the two restrictors. The coolant inflowing to the guide rod therefore returns by way of the second annular gap, the second pressure chamber and the first annular chamber to the pressure vessel which extends around the reactor core. Control means are provided to enable pressure surges to be produced as required in the coolant in the first pressure chamber.
