Title: Synthetic resin bottle with handle and its production method
Inventor: ISHII HIROICHI
IPC: B65D23/10
Filed: 1994-05-16
Abstract: In a bottle made of synthetic resin of the present invention, a handle is combined to a bottle body so that the bottle can be easily handled for carrying it and pouring the content. When the joint of the handle to the bottle body is unstable, it is difficult to handle the bottle and it will occur an accident when the handle comes off the bottle body.      Therefore, in the present invention, a reinforcing structure is provided to necessary portions not to deform the joining portion of the handle to the bottle body and further a coming off-preventing mechanism is provided so that the handle does not comes off the bottle. The coming off-preventing mechanism is accomplished by a supporting projection and/or a supplementary engaging protruding portion and a supplementary engaging recess portion. To ensure the coming off-preventing mechanism, the bottle body is formed by biaxial oriented blow molding with assembly beams of the handle as an insert.

Title: Simultaneous voice and data call establishment using a simultaneous voice and data modem pool and private branch exchange facilities
Inventor: HOLMQUIST KURT E
IPC: H04Q3/58
Filed: 1995-02-21
Abstract: A simultaneous voice and data (SVD) modem includes two analog ports and a data terminal port. Both of these analog ports are capable of transmittingtelephone numbers and are coupled to a switching system like a private branch exchange (PBX). The data terminal port is coupled to a data terminal of an SVD user. In one embodiment of the invention, the SVD user, the calling party, sends at least one command to the SVD modem, via the data terminal port. In response, theSVD modem separately transmits, to the PBX, the calling party number from one ofthe analog ports and the called party number from the remaining analog port. TheSVD modem then subsequently communicates any voice signals received on one of the analog ports to the other analog port. This allows a voice call to be switched through the SVD modem, yet requires no modification to the PBX.

Title: Antibodies detecting stromelysin cleavage products
Inventor: MUMFORD RICHARD A
IPC: A61K39/395
Filed: 1993-09-21
Abstract: Monospecific antibodies are produced which are specific for fragments of the connective tissue protein aggrecan, generat-ed by specific stromelysin cleavage. These monospecific antibodies are used in an assay system to detect polypeptide fragments of aggrecan, produced by the specific cleavage of aggrecan by stromelysin. The presence of aggrecan polypeptide fragments demon-strates stromelysin activity. Elevations of stromelysin occur in osteoarthritis, rheumatoid arthritis, atherosclerotic lesions, gout, in-flammatory bowel disease (IBD), idiopathic pulmonary fibrosis (IPF), certain cancers, joint injuries, and numerous inflammatory diseases. The monospecific antibodies and the assay system are used to quantitate aggrecan polypeptide fragments as a readout of stromelysin activity and to evaluate potential stromelysin inhibitors.
