Patent CA-2049616-A1 (CA)
Inventor: SOIFERMAN JACOB
IPC: G01R31/309
Filed: 1991-08-21
Abstract: This application describes a novel method and its implementation for testing unpopulated and populated electronic printed circuit boards (PCBs).  This method can be used to develop a new contactless test system (CTS). While eliminating drawbacks of existing test systems, this method measures electromagnetic near field distribution in the vicinity of a PCB, contactlessly, by using suitable sensors (possibly printed near field planar antennas) and sensitive measuring and processing devices. The electromagnetic fields (EMF) are generated by the distribution of charges and currents on paths and elements of the board under test (BUT). Therefore, accurate and repeatable measurements of these fields produce a specific pattern for the BUT. Such a pattern is then compared to a known pattern for the same type of board to determine whether the BUT is faulty or non-faulty.

Title: Retractable lifeline safety device
Inventor: WOLNER JAMES T
IPC: B66D5/04
Filed: 1991-10-25
Abstract: A retractable lifeline safety device usable by workers performing tasks at great heights above the ground. The mechanical components of the safety device are contained within a sealed housing that is filled with a viscous fluid. The sealed housing prevents the introduction of dirt, moisture and other foreign matter into the mechanical mechanism of the safety device, reducing the likelihood that those components may be fouled by dirt and corrosion, which in turn could greatly reduce the effectiveness of the safety device. The safety device is attached to the structure on which the worker is performing the task, and a lifeline such as a cable is withdrawn from the housing thereof, the end of which is attached to a belt or harness worn by the worker. The cable may be easily drawn out of the housing in response to the worker moving about normally in the appropriate work space, and the cable is automatically drawn back into the housing of the safety device as the worker draws closer thereto. However, should the worker fall, a brake within the safety device is automatically engaged by a centrifugal clutch, stopping the worker's descent.

Abstract: Selectively digesting the Group B Streptococcus type III  (GBS-III) polysaccharide capsule (PC) to yield fragments consisting of intact GBS-III polysaccharide capsule repeating units. GBS-III  polysaccharide capsule is digested by reacting it with a bacterial endo-.beta.-galactosidase that is specific for the galactose-glucose glycosidic linkage in the GBS-III CP backbone, and that substantially does not hydrolyse any other GBS-III CP glycosidic linkages. The resulting polysaccharide fragments are recovered and are immunologically useful. The endo-.beta.-galactosidase is produced in a multiphase culture that comprises: i) a liquid aqueous phase;  ii) a second phase that is aqueous insoluble and in contact with the liquid aqueous phase at an interface therebetween, and iii) bacterial cells positioned generally in the liquid aqueous phase and at the interface between the liquid aqueous phase and the second phase. The endo-.beta.-galactosidase is recovered from the liquid aqueous phase.
