Patent YU-40999-A (YU)
Title: N-hydroxy-2-(alkyl,aryl,or heteroaryl sulfanyl,sulfinyl or sulfonyl)-3-substituted alkyl,aryl or heteroarylamides as matrix metalloproteinase inhibitors
Inventor: ARANAPAKAM VENKATESAN MUDUMBAI
IPC: C07D215/48
Filed: 1998-02-17
Abstract: Matrix metalloproteinases (MMPs) are a group of enzymes that have been implicated in the pathological destruction of connective tissue and basement membranes. These zinc containing endopeptidases consist of several subsets of enzymes including collagenases, stromelysins and gelatinases. TNF-'alpha' converting enzymes (TACE), a pro-inflammatory cytokine, catalyze the formation of TNF-'alpha' from membrane-bound TNF-'alpha' precursor protein. It is expected that small molecule inhibitors of MMPs and TACE therefore have the potential for treating a variety of disease states. The present invention provides low molecular weight, non-peptide inhibitors of matrix metalloproteinases (MMPs) and TNF-'alpha' converting enzyme (TACE) for the treatment of arthritis, tumor metastasis, tissue ulceration, abnormal wound healing, periodontal disease, bone disease, diabetes (insulin resistance) and HIV infection. The compounds of this invention are represented by formula (I), where R1, R2, R3 and R4 are described herein.
Patent AT-A156990-A (AT)
Inventor: NIEDER WOLFGANG DIPL ING
IPC: C21C5/42
Filed: 1990-07-26
Abstract: In a process for smelting steel from scrap and/or metal-containing, waste-like materials, the continuously or discontinuously introduced metal carriers are preheated and melted in a fixed bed, and oxygen-containing gases are injected via at least one secondary nozzle level in the region of the fixed bed and/or above the fixed bed. The waste gas from the fixed-bed reactor (1) is fed to a thermal reactor (22) and heated to temperatures of 1000 DEG C to 1500 DEG C, in particular 1000 DEG C to 1200 DEG C. The waste gas leaving the thermal reactor (22) is passed via at least one filter (31) and is subjected to chemical flue gas treatment (38), after which the treated or physically or chemically prepurified flue gas is optionally subjected to final purification via an active carbon filter (46). <IMAGE>

Abstract: STACKED FLEXIBLE RECORD DISK STORAGE APPARATUS    HAVING ENHANCED DISK SEPARATION USING A    PRIMARY BENDING MODE IN A STACK OF DISKS           Abstract A signal storage apparatus employs a stack of circular record disks accessible by axially separating segments of selected disks in the stack.  One disk in a stack of coaxial rotatable circular compliant record disks is accessed with a minimum energy imparted to such disks by a chord roll disk separator.  In a preferred form, the chord roll disk separator induces a primary bending mode to some of the disks being axially sepa-rated.  In another aspect of the disclosure, a signal transducer is mounted integrally with the disk separator.          With such mounting, primary, secondary, or higher order bending modes may be successfully employed.  Full chordal and partial chordal axial disk separations are described.          Arcuate and radially directed separation techniques may be employed.  A unique axial stacking arrangement for compliant record disks is also described.

Abstract: ABSTRACT         A pump comprises a tubular resilient pump element alternately extended and relaxed for longitudinal deformation and reinforced by means of filaments arranged in helices, preferably with helices of opposite hands present, whose pitch angle is other than arccot  , so longitudinal deformation will result in volumetric changes.  Inlet and outlet valves ensure inidirectional flow through the pump element.        To smooth out flow a similarly constructed accumulator element, whose reinforcement pitch angle is chosen with a value such that the pump and accumulator pitch angles are on opposite sides of arccot  , is arranged to undergo simultaneous and similarly directed longitudinal deformation and to have a volumetric change of opposite sign, and preferably half the value, with regard to that of the pump element whereby during the inlet stroke of the pump element the accumulator element, which communicates with the discharge flow path from the pump element, will advance a proportion, preferably half, of the delivery of the previous discharge stroke of the pump element.
