Abstract: TITLE PHOTOPOLYMER COMPOSITION FOR THE PRODUCTION OF           THREE-DIMENSIONAL OBJECTS       ABSTRACT A process for forming a three-dimensional object comprises repeatedly imagewise exposing the surface of a reservoir of liquid photohardenable composition, curable by actinic radiation, with actinic radiation to harden the liquid composition near the surface to form a plurality of superimposed layers of hardened composition.  In this invention, the liquid photohardenable composition consists essentially of:      (a)  25 to 65% of a difunctional acrylated polyurethane oligomer or a mixture of the oligomers;      (b)  15 to 65% of a polyglycol ester of the following formula:                 H2C=CR(CO)-O(CH2-CH2-O)n-(CO)RC=CH2 wherein:      R is hydrogen or methyl, and n is an integer from 2 to 5; or a mixture of the polyglycol esters; (c)  0.1 to 10% of a photoinitiator system sensitive to the actinic radiation or a mixture of the photoinitiator systems; and (d)  0 to 30% of a polyfunctional reactive diluent or a mixture of the reactive diluents;      wherein the liquid photohardenable composition has a viscosity of 200 to 8000 cP at 25°C.

Patent CA-2077280-A1 (CA)
Inventor: STRANDGAARD JAN
IPC: G05D16/16
Filed: 1992-09-01
Abstract: A valve controlled in dependence on differential pressure with a set-point setting facility, comprises a valve housing (4), a diaphragm housing (16), and a setting device (3) which is removable as a unit from the diaphragm housing (16).  A pin (36) connected to the diaphragm (23) projects in a sealed manner from the diaphragm housing (16).   The set-point spring  (50)  extends between an adjustable supporting plate (51) and a spring plate (52).  The forces of the set-point spring (50) are transferred by way of a releasable coupling (64) to the pin (36).   The coupling (64)  is in particular designed to transfer tensile forces.  In this manner, the set-point spring can be adjusted  or  exchanged  at  any  time.    In  addition,  detrimental transverse forces originating in the set-point spring are prevented from being transferred to the valve rod. The valve is therefore accessible and of low friction.

Title: Tgf-.beta.1/.beta.2: novel chimeric transforming growth factor-beta
Inventor: PURCHIO ANTHONY F
IPC: C12P21/02
Filed: 1992-03-13
Abstract: The present invention relates to the production of large quantities of a novel chimeric TGF-.beta., termed TGF-.beta.1/.beta.2, by eucaryotic host cells transfected with recombinant DNA vectors containing the TGF-.beta.1/.beta.2 precursor coding sequence controlled by expresson regulatory elements. Simian TGF-.beta.1 cDNA  (Sharples et al., 1987, DNA 6:239-244) was modified so that the nucleotides encoding amino acid residue numbers 9-13, 17, 19, 25 and 26 of the mature TGF-.beta.1 sequence were hanged to the nucleotides encoding the corresponding amino acids of the mature TGF-.beta.2 structure. Simian codon usage was maintained. The chimeric TGF-.beta.1/.beta.2 of the invention induces effects on the proliferation of vascular endothelial cells equivalent to those induced by TGF-.beta.1 (see Section 7., et seq.).

Filed: 1993-09-10
Abstract: FINGERPRINT VERIFICATION SYSTEM     Abstract A fingerprint verification system is disclosed which can be used as a fast and effective security device to verify that an applicant to a service protected by the system is authorized to use the system.  This security check is performed through a correlation operation. Electronic information allowing the creation of a correlation filter on a spatial light modulator (SLM) is input from a smart card or fingerprint database to an SLM. The fingerprint or cluster of fingerprints of the applicant are then correlated through the  SLM in order to derive a comparison with those electronically stored. Although the system used electronically stored pattern information, the correlation is performed optically.
