Patent CA-2205035-A1 (CA)
Title: A working platform
Inventor: KRAUSE GUENTHER
IPC: E04G1/15
Filed: 1995-08-16
Abstract: Working platforms for scaffolding must be light and functional and easily stackable. It must therefore be possible to include all their components with a long useful life in the static calculation as well. The requirements include both great regidity in the corner joint of a rectangular bearing frame for the working platform and the smallest possible gaps between adjacent platforms.  Above all, however, the smallest possible number of components must keep the costs of such a working platform within limits. To this end the invention makes use of a U-shaped folded footplate (2) clamped between the longitudinal bearers (11) of the bearing frame. If, in addition, at least the longitudinal bearers (11) are rectangular hollow sections, no dirt or residual building material can enter the working platform.

Title: Plug portion for an optical fiber connector
Inventor: DE MARCHI SILVERIO
IPC: G02B6/38
Filed: 1997-07-03
Abstract: A plug portion (1) for an optical plug connector has a plug casing (2) in which at least one connector pin (3) is held. A protective flap (4) for protection of the connector pin is pressed under spring tension against the face (7) of the plug casing. The protective flap is mounted to pivot and slide on an approximately linear guide path (5) in such a way that, on insertion of the plug portion into a sleeve portion, it is able to move from a closed position on the face of the plug casing into an opened position that is set back in relation to the face (7). In order to pre-load the protective flap under spring tension throughout its entire slide- and pivo- ting-travel, a compression spring is arranged on the plug casing (2) approximately parallel to the guide path (5), said compression spring impinging either directly or indirectly upon the protective flap (4) above the plane of the guide path (5) between the closed position and the opened position.

Title: Method of deblocking, extracting and cleaning polymeric articles with supercritical fluid
Inventor: TERRY WILSON LEONARD JR
IPC: B29C39/36
Filed: 1996-02-09
Abstract: Methods of deblocking a polymeric article from a mold and/or removing undesirable materials from a polymeric article by applying supercritical fluids to the polymeric article are disclosed. A preferred process is the treatment of ophthalmic lenses, such as contact lenses (16). Supercritical fluid, composed primarily of carbon dioxide, is applied to a contact lens (16) affixed to a mold (18) subsequent to the polymerization step. The application of supercritical fluid (SCF) causes the lens to efficiently and consistently separate from the mold, removes undesirable materials such as unreacted monomer oligomers, or residual solvents from the lens core, and/or cleans the lens surface of adhered debris.

Title: System for controlling the temperature of a temperature control fluid in an internal combustion engine
Inventor: HOLLIS THOMAS J
IPC: F01P7/14
Filed: 1996-05-16
Abstract: A temperature control system in an internal combustion engine includes a heating arrangement which channels a flow of temperature control fluid from an engine to and from an exhaust heating assembly (142) which is located adjacent to an exhaust manifold (140) in the engine. The exhaust heat assembly (142) permits the transfer of heat from the exhaust gases flowing in the exhaust manifold (140) to the temperature control fluid. The heated temperature control fluid is then directed back to the engine for efficient heating. In one embodiment, the temperature control fluid is directed through a heat exchanger in the engine oil pan (28) so as to maintain the temperature of the engine lubricating oil at or near its optimum operating temperature. In a second embodiment, the temperature control fluid is directed from the exhaust heat assembly to the intake manifold (130) so as to increase the temperature of the intake air prior to combustion.

Patent CA-2224071-A1 (CA)
Inventor: NAUGHTON GAIL K
IPC: A61K35/28
Filed: 1996-06-03
Abstract: The present invention relates to a stromal cell-based three-dimensional cell culture system which can be used to culture a variety of different cells and tissues in vitro for prolonged periods of time. The stromal cells and connective tissue proteins naturally secreted by the stromal cells attach to and substantially envelope the framework composed of a biocompatible non-living material formed into a three-dimensional structure having interstitial spaces bridged by the stromal cells. The living stromal tissue so formed provides the support, growth factors, and regulatory factors necessary to sustain long-term active proliferation of cells in culture and/or cultures implanted in vivo. When grown in this three-dimensional system, the proliferating cells mature and segregate properly to form components of adult tissues analogous to counterparts in vivo, which can be utilized in the body as a corrective tissue. For example, and not by way of limitation, the three-dimensional cultures can be used to form tubular tissue structures, like those of the gastrointestinal and genitourinary tracts, as well as blood vessels;  tissues for hernia repair and/or tendons and ligaments; etc.

Patent CA-2242134-A1 (CA)
Inventor: OLSON ERIC O
IPC: H02P1/02
Filed: 1998-06-29
Abstract: A device which intervenes between an electric switch and a motor which it controls, such intervention reducing the number of times the motor is powered on by keeping the motor running. The device calculates the difference in the amount of energy used in starting compared with normal running. Then, it calculates how long the motor must be turned off, if turning it off is to be economical. If the motor is turned off for a period which is not economical, the motor control device will intervene and keep the motor running until it is no longer economical to keep it running. In applications where an industrial tool is being used so frequently that it is being stopped, then started again in short intervals, this device would keep the tool running constantly until a sufficient period since the last use has lapsed and the device is allowed to shut the motor off.
