Title: Stent having a multiplicity of closed circular structures
Inventor: FISCHELL ROBERT E
IPC: A61F2/90
Filed: 1995-02-20
Abstract: The present invention provides for an expandable stent for use in an artery or other vessel which forms a plurality of spaced apart generally circular rings. The stent structure (1) maintains patency of a vessel within which the stent is inserted and is formed by a plurality of closed and generally circular rings where the plane, of each ring (2) is substantially parallel to the plane of an adjacent ring. The rings have a common longitudinal axis generally perpendicular to the plane of each ring with the longitudinal axis passing through the geometric center of each of the rings. A plurality of elongated wire structures forming longitudinals are fixedly secured to the rings and extend in a direction generally parallel to the longitudinal axis of the rings. The stent formed of the generally circular rings optimizes hoop strength and minimizes elastic recoil of a vessel into which the stent is inserted.

Title: Low-noise rotary control valve
Inventor: LEINEN CHRIS
IPC: F16K5/06
Filed: 1993-09-15
Abstract: A low-noise rotary control valve includes a valve body (10) and a rotatable ball (12). An upwardly extending diverter (28) is positioned in the entry flow passage (15) of the ball (12). A downwardly extending diverter (30) is disposed on the leading edge of the upper half of the valve (12). The diverters (28, 30) provide a small impedance to flow when the valve is in the full open posi-tion, but provide a tortious path for fluid flow when the valve is partially closed. The tortious path inhibits vortex formation re-sulting in reduced noise and vibration. A third impediment (32) in the outflow passage (16) extends upwardly from the valve and inhibit vortex formation downstream of the valve.

Accordingly,  when pressure is applied against the bottom end of the bag,  such as when placing an article or articles therein, the load applied onto the bottom end will be distributed along the diagonal seams of the flap away from the apex point with the flap maintaining the bottom wall substantially rectangular.
Patent CA-2145670-A1 (CA)
Title: Text input font system
Inventor: DAVIS MARK E
IPC: G06F17/21
Filed: 1994-01-03
Abstract: A method and system for automatically selecting a font so that a user sees the characters and fonts expected to appear in a document. The preferred embodiment of the invention employs a first process when a character, or string of characters, is entered into a text stream. If the character is missing from the font specified in the current typing style, the process selects a font that can display the character. For example, if the code for a ".SIGMA." is inserted before "n/2" the process would automatically style the code with a font that could display the ".SIGMA.". Styling a character means that the character will always have a font style associated with the character.

Patent CA-2155902-A1 (CA)
Inventor: RASCHBICHLER HANS GEORG
IPC: E01B1/00
Filed: 1995-08-11
Abstract: In  a  method  for  exactly positioning  and applying fastening elements within mounting bodies of a track support of a track system for a track-bound transport system a track support is first manufactured,   and  during  manufacture,   in  a manufacturing  position  of  the  track  support, preset coordinates for a connecting location of the fastening elements at the mounting bodies are defined.   After completion of manufacture and abandoning the manufacturing position, the exact actual spatial position of the track support is measured.   The actual spatial position of the track support is compared with the manufacturing position of the track support.  The differential spatial  position  between  the  actual  spatial position  and  the  manufacturing  position  is assessed.  Based on  the  differential  spatial position,  the positional  change of the preset coordinates  of  the  connecting  location  is determined  and  corrected  coordinates  for  the connecting location based on the positional change are generated.
Patent CA-2157381-A1 (CA)
Inventor: EDMONDS TIMOTHY KENT
IPC: A01G9/10
Filed: 1993-03-02
Abstract: The invention relates to the automated planting of plantlets from a bare-root, cutting or tissue culture condition into a nursery container. The invention creates a continuous supply of v-notches (34) or open "sandwiches" or "books" of potting substrate, into which plantlets are placed, which then are closed around the plant roots or stem prior to automatic transplantation into a nursery container (46). The invention especially enables plantlets with small roots to be quickly and efficiently planted by an operator by "sandwiching" roots without injury or transplant shock. It is contemplated that this manual planting could be satisfactorily automated.  The invention is useful for small plantlets or early stage germinants that have both root and shoot (such as tissue culture material derived from either micropropagation or somatic embryogenesis), but can also be used with rooted or unrooted cuttings, true or synthetic seed or naked embryos.

The adjusting nuts preferably have a head portion and a body portion, in which the head portion has a width greater than the width of the body portion. Thus, the head portions of the adjusting nuts are contactable with respective opposed ends of the housing. Alternatively, or in addition, the housing may have an interior ledge provided within the housing bore, and leading edges of the adjusting nuts which are disposable within the housing may contact the interior ledge.

Title: Nadh and nadph therapeutic agents for nasal, sublingual, rectal and dermal administration
Inventor: BIRKMAYER JOERG G D
IPC: A61P25/28
Filed: 1996-01-12
Abstract: NADH and/or NADPH is applied topically to the skin.  It was surprising and totally unexpected to discover that NADH and NADPH are absorbed by the skin and penetrate the cutis to be taken up by the skin cells, where they stimulate certain enzymes which are essential for the energy production of the cells.  The enzymes stimulated are principally the mitochondrial enzymes.  The NADH and/or NADPH can be incorporated into a skin compatible cream, lotion or cosmetic.  Liposomes are ideal vesicles for carrying the NADH and/or NADPH into the skin.  In other embodiments of the invention, NADH and/or NADPH is administered nasally (e.a., as a liquid spray or a powder spray through the nostrils), sublingually (e.g., in the form of uncoated tablets inserted underneath the tongue) and rectally (e.q., in the form of suppositories) for known therapeutic effects (e.q., the treatment of Parkinson's disease).
