Patent CA-2216508-A1 (CA)
Inventor: STENNETT PATRICK G
IPC: A63B49/10
Filed: 1997-09-25
Abstract: The present invention relates to an improved construction for sporting equipment,  particularly,  tennis racquets,  racquetball racquets, and squash racquets.  Specifically, the construction of the  present  invention  includes  composite  rods  blended,  or interspersed, between layers of bias angled pre-preg composite materials.   Such a construction exhibits enhanced compressive strength, bending stiffness, axial stiffness, and fatigue strength.          Such enhanced  characteristics  provide  a  racquet  superior  to racquets constructed with no composite rods inclusion. Composite rods are inherently stiff and exhibit a minimal degree of "fiber waviness" (much less than exhibited by hand-rolled or machine lay-ups).   Fiber waviness can cause a composite structure to weaken under compressive and bending loads.  Therefore, the composite rod inclusion in  the  present  invention  results  in  a  composite construction  that  is  stiffer  and  stronger  than  a  structure constructed with the conventional method of lay-up construction (no rod inclusion).  Because of the lower degree of "fiber waviness" in their structure, composite rods display compressive strength and strain constants that are almost equal to their tensile strength and strain constants.  Therefore, when rods are placed in composite structures, these resulting structures display enhanced compressive strengths  and stiffness.  Delamination strength is also increased, giving the structures better fatigue qualities.  The inclusion of rods in a composite structure also allows for the construction of a composite structure with a high strength to weight ratio.

Title: Power weaving loom
Inventor: SPEICH FRANCISCO
IPC: D03D49/60
Filed: 1996-03-06
Abstract: A power weaving loom has a shed (6) made of warp threads (6) in which a reed (14) is guided back and forth.      Weft thread insertion means (26), for example shaped as an insertion band (28) guided on guiding elements (24) linked to a reed lever (23) of the reed (14), are used to insert the weft thread. The guiding elements (24) are coplanar to the mid-plane of a corresponding reed tooth (18a), said mid-plane extending in the direction of motion of a reed tooth (18a). A deflecting member (36) that extends on both sides of the mid-plane in the direction of the weft thread for reliably guiding a warp thread past the guiding element (24) and avoiding interlocking is arranged between the reed tooth (36) and the guiding element (24). Parallel yarns may thus be used in such a power weaving loom even in a high performance range.

Title: Gas oven fuel control with proof of ignition
Inventor: MAUGHAN JAMES ROLLINS
IPC: F24C3/12
Filed: 1997-10-17
Abstract: A gas oven having an electronic controller for directly controlling the gas valve and burner ignition. The controller opens the gas valve and activates the ignitor whenever oven heating is required and then determines whether ignition has occurred, detected by an indicator of ignition, often a conventional oven thermostat, a thermocouple, a resistance temperature device (RTD), or other type of temperature sensor. Positive proof of ignition is given by determining whether the detected temperature is increasing at a particular rate. The gas valve is closed if ignition does not occur within a predetermined time, preferably about 10-15 seconds. Re-ignition may be attempted after a sufficient delay. The controller also closes the gas valve whenever the oven temperature is decreasing at a predetermined rate or is increasing at less than a predetermined rate.

Abstract: Multi-layer injection molding apparatus having integral multi-layer melt dividing bushings seated in the melt distribution manifold for dividing a first melt passage extending to annular melt channels in heated nozzles. Matching melt channels machined in the front face of the first layer and the rear face of the second layer of each melt dividing bushing form a melt conduit which branches from an inlet to two spaced holes extending through the second layer. A pair of matching melt channels machined in the front face of the second layer and the rear face of the third layer of each melt dividing bushing form two melt conduits, each of which branch from one of the holes through the second layer to two of four spaced holes through the third layer. The four holes through the third layer align with four melt bores leading to the annular melt channel in one of the heated nozzles. A second melt passage may extend through a central bore in each melt dividing bushing to a central melt channel in the heated nozzle. In another embodiment, the first melt passage also extends through central holes in the second and third layers of the melt dividing bushing to a central melt channel in the heated nozzle. In this case, the second melt passage may extend through a melt bore through the melt dividing bushing or may similarly divide into two in a melt conduit extending between two of the layers of the melt dividing bushing.

Title: Heart valve replacement using flexible tubes
Inventor: COX JAMES L
IPC: A61L27/36
Filed: 1995-12-28
Abstract: This invention comprises a method of using tubular material (200) to replace a heart valve (118, 120, 162) during cardiac surgery. To create a replacement atrioventricular (mitral or tricuspid) valve (120, 160), the tube inlet is sutured to a valve annulus (121, 162) from which the native leaflets have been removed, and the tube outlet is sutured to papillary muscles (126, 128, 170) in the ventricle (112, 152). To create a semilunar (aortic or pulmonary) valve (118), the tube inlet is sutured to an annulus from which the native cusps have been removed, and the tube is either "tacked" at three points distally inside the artery, or sutured longitudinally along three lines; this allows the flaps of tissue between the three fixation points at the valve outlet to function as movable cusps. These approaches generate flow patterns that closely duplicate the flow patterns of native valves. A  preferred tubular material (200) comprises submucosal tissue from the small intestine; this can be taken from the same patient who is undergoing the cardiac operation, to reduce antigenicity. Animal or cadaver intestinal tissue can also be used if properly treated, or a biocompatible synthetic tubular material can be used. This invention also discloses a properly treated intestinal tissue segment or synthetic tubular segment (500) suitable for implantation as a replacement heart valve, enclosed in a sealed sterile package (510).
