Title: Process for producing aminocarboxylic acid salt
Inventor: URANO YOSHIAKI
IPC: C07C229/16
Filed: 1991-11-26
Abstract: The present invention provides a novel process for producing an aminocarboxylic acid salt which is useful as a material for agricultural chemicals and drugs, a chelating agent, a food additive, etc. The process produces an aminocarboxylic acid salt from an aminoalcohol by subjecting the aminoalcohol to an oxida-tive dehydrogenation reaction in the coexistence of an alkali metal hydroxide and/or an alkaline earth metal hydroxide, a copper-containing catalyst and water, and is characterized by performing the reaction while maintain-ing the nickel concentration in the reaction mixture at 40 ppm or less.

Abstract: "Polymer electrolyte membrane, and process for the production thereof"        In order to produce a polymer electrolyte membrane from sulfonated, aromatic polyether ketone, an aromatic polyether ketone of the formula (I)   in which Ar is a phenylene ring having p- and/or m-bonds, Ar' is a phenylene, naphthylene, biphenylene, anthrylene or another divalent aromatic unit, X, N and M, independently of one another are 0 or 1, Y is 0, 1, 2 or 3, P is 1, 2, 3 or 4, is sulfonated and the sulfonic acid is isolated. At least % of the sulfonic groups in the sulfonic acid are converted into sulfonyl chloride groups, and these are reacted with an amine containing at least one crosslinkable substituent or a further functional group, and unreacted sulfonyl chloride groups are subsequently hydrolyzed. The resultant aromatic sulfonamide is isolated and dissolved in an organic solvent, the solution is converted into a film, and the crosslinkable substituents in the film are then crosslinked.        In specific cases, the crosslinkable substituents can be omitted. In this case, sulfonated polyether ketone is converted into a film from solution.

Title: Steroid eluting intramuscular lead
Inventor: GRANDJEAN PIERRE-ANDRE
IPC: A61M60/882
Filed: 1991-12-23
Abstract: An intramuscular lead for electrically stimulating muscle tissue particularly configured for a cardiac assist system powered by surgically modified skeletal muscle tissue. Electrical stimulation is supplied via the intramuscular lead to cause contraction of the skeletal muscle in synchrony with the natural or artificially paced heart rate and timed to obtain the desired hemodynamic effect. The improved lead has an electrode which is embedded in the skeletal muscle. The stimulation threshold of the skeletal muscle is held relatively low by the action of a glucocorticosteroid imbedded within the strand of suture material. A spacer coil of biocompatible material is coiled around the strand of suture material, such that the turns of both coils are substantially interleaved.  The spacer coil is saturated with a specific agent such as steroid or antibiotic. The compression movement of the muscle tissue and the electrode coil against the spacer coil will cause the drug to be dispensed therefrom.

Abstract: ABSTRACT OF THE DISCLOSURE                A BEVEL ANGLE INDICATOR     A bevel angle indicator for a saw is disclosed. The saw 10 consists of a table 16, a pivot support 26 pivotally mounted with respect to the table 16 about a bevel axis 92 and a mechanical saw blade pivotally mounted with respect to the pivot support 26 about a second axis 28.  The pivot support 26 pivots on a pivot block 27 attached to the table 16.  A gearing mechanism couples the pivot block 27 and the pivot support 26 to a dial which indicates the angle between the surface of the table 16 and the plane of the saw blade.  The gearing mechanism comprises a rack 50 attached to the pivot block 27 and a pinion 54 rotatably journalled in the pivot support 26.  Adjustment of the bevel angle of the saw 10 causes the pinion 54 to advance along the rack 50 and therefore rotate relative to the pivot support 26.  The pinion 54 is attached to a sleeve 52, the free end of which carries a pointer 56;  the pivot support 26 carries a scale 58. The pointer 56 and scale 58 indicate with accuracy the current bevel angle of the saw.       (Figures 2 and 3)
