Title: Column assembly ii
Inventor: SIMEONOFF GEORGE
IPC: E04C3/30
Filed: 1993-04-05
Abstract: ABSTRACT OF THE DISCLOSURE             A column assembly having a plurality of floor-height columns which are erected vertically, one on top of the other, to define the floors of the building structure to be constructed.  Each column comprises a plurality of reinforcement rods which are embedded in the column and extend outwardly from the ends thereof. The rods are cut at precisely equal lengths to extend precisely equal distances from each end of the column.  Each rod is threaded in a precise manner with the thread beginning at the same orientation for each rod such that when the columns are stacked end-to-end, the rods are in perfect axial alignment with the thread of one rod continuously leading into the thread of the contiguous rod to which it is aligned.  A threaded sleeve is threaded onto the rods extending from the lower end of the upper column and, after stacking of the upper column end-to-end onto a lower column, the threaded sleeve may be threaded onto the axially aligned and contiguous rods extending from the lower column.  A rigid mechanical connection is therefore made between adjacent columns sufficient to support the columns vertically without additional shoring.

Patent CA-2096179-A1 (CA)
Title: Optical fiber amplifier
Inventor: NISHIMURA MASAYUKI
IPC: H01S3/067
Filed: 1993-05-13
Abstract: Pumping light from an optical pumping source is incident on an Er-doped fiber through a multiplexer to pump Er. When signal light is incident on the Er-doped fiber through the multiplexes in this state, the signal light is amplified by stimulated emission of pumped Er.      This amplified signal light is attenuated by a high-loss optical fiber and is output externally through a splitter and the like. Meanwhile, part of the amplified signal light is fed back to a driving source of the optical pumping source through the splitter so as to be used to adjust the gain of the optical fiber amplifier. With this operation, the output signal power is kept constant. In this case, since the high-loss optical fiber is connected to the output terminal of the Er-doped fiber, the noise figure of the optical f fiber amplifier can be kept small over a wide range of input light intensities.

Patent CA-2103371-A1 (CA)
Inventor: WU GEORGE Y
IPC: C12N15/87
Filed: 1992-06-05
Abstract: Molecular complexes for targeting a gene encoding a secretory protein to a specific cell en vivo and obtaining secretion of the protein by the targeted cell are disclosed. An expressible gene encoding a desired secretory protein is complexed to a conju-gate of a cell-specific binding agent and a gene-binding agent. The cell-specific binding agent is specific for a cellular surface structure which mediates internalization of ligands by endocytosis. An example is the asialoglycoprotein receptor of hepatacytes.   The gene-binding agent is a compound such as a polycation which stably complexes the gene under extracellular conditions and releases the gene under intracellular conditions so that it can function within a cell. The molecular complex is stable and soluble in physiological fluids and can be used in gene therapy to selectively transfect cells in vivo to provide for production and secre-tion of a desired secretory protein.
