Patent CA-2048369-A1 (CA)
Inventor: GUEVARRA FERDINAND A
IPC: F16B21/09
Filed: 1991-08-02
Abstract: ABSTRACT   A fastener arrangement is provided for the clamping together of two objects, such as the adjacent sidewalls of enclosures or the like. The fastener arrangement is used with predetermined aligned openings in the objects to be fastened and is installable from either side of the objects. The fastener arrangement includes a first member insertable through the predetermined aligned openings from either side of the two objects. The first member includes two spaced-apart, facing damping surfaces. Upon insertion of the first member into the installed position, each of the clamping surfaces engages one of the respective sidewalls. After insertion of the first member, the desired clamping force is applied. In a specific embodiment, the first member carries a threaded stud that extends from the side from which it is installed. A nut is assembled onto the stud to apply the clamping force. The dimensions of the predetermined aligned openings and the fastening arrangement are related so that the first member is easily insertable into the opening, but cannot fall through to the other side. Further, the first member does not need to be held in any way and is both self-supporting and self-aligning during installation and clamping. Thus, assembly merely involves the placing of the first member through the aligned opening, whereupon it is self-guiding into the assembled position, and thereafter applying the clamping force. The arrangement is also easily removable and reusable. Additionally, the first member closes off the opening between the two sides. In a specific embodiment, the predetermined opening is generally T-shaped.

Title: Ravel-resistant, self-supporting woven graft
Inventor: SCHMITT PETER J
IPC: A61F2/06
Filed: 1991-08-27
Abstract: A ravel-resistant, self-supporting woven synthetic fabric  tubular  vascular  graft  including  a  fusible  fiber integrated into the weave in the filling yarn is provided.  The graft is woven from multifilament polyester warp yarns which can be textured or flat.   The filling yarn includes a low melting fusible fiber or resin which can be combined with a stiff monofilament.  The monofilament component provides radial rigidity to improve kink and crush resistance.   After heat setting, the low melting fusible resin fuses to orthogonal warp yarns at each intersection and provides ravel resistance to the finished graft.   Improved kink resistance make the tubular grafts suitable for use in medium and small diameter peripheral applications.  A preferred graft has an outer velour surface and a smooth inner surface.

Inventor: AMBERGER CHARLES J
IPC: C03C17/34
Filed: 1991-10-07
Abstract: An anti-reflective coating employing silicon as a high refractive index material in a film pair together with silicon dioxide as a low refractive index material is found to be substantially transparent to visible light and to provide good anti-reflectance where the silicon film  is  ultra-thin,  preferably  less  than  about  50 Angstroms and the thickness of the silicon dioxide film is matched to that of the silicon film.   Laminated glazing units having such anti-reflective film can be used, for example, even in applications requiring high transmittance of visible light, such as motor vehicle windshields, in view of the substantial transparency of the coating.

Title: Toy doll
Inventor: LAM WING F
IPC: A63H3/28
Filed: 1992-01-07
Abstract: ABSTRACT          A battery-powered doll which cries or laughs, depending upon how it has been stimulated.  There is an optical sensor fixed in the mouth of the doll and connected to an integrated circuit located in the torso of the doll.  When there is insufficient light striking the sensor, the doll cries through a speaker in the doll's torso.  When the doll is subsequently brought into the light to sufficiently expose the sensor, the doll laughs for a short, but variable length of time.  There is a first pressure actuated switch positioned in the doll's torso such that it may be actuated by a tickling type of pressure applied to the side of the torso.  The doll laughs when this switch is actuated.  There is a second pressure actuated switch in the doll's torso which may be activated by pressing the stomach area of the doll.  The doll cries in response to actuation of this second switch.  The crying of the doll may be interrupted by triggering of the laughing sound, but the crying sound may be triggered only when the doll is not laughing.
