Abstract: A process and apparatus is described for providing a strip of flexible closure material to be affixed to a receptacle. The strip of flexible closure material comprises a combination of a plurality of interengaging strip portions in their interengaged state.  The process includes the step of supplying a tape of flexible closure material having a transverse width with a plurality of interengaging elements across the transverse width that extend from the tape. Then, the tape is separated along its longitudinal length into a plurality of strip portions with at least two of the strip portions having an interengaging element extending therefrom.  Lastly, the strip portions having an interengaging element are brought into contact with one another while mating the interengaging element of each of the strip portions brought together with that of the other. The process takes place continuously in line with equipment for affixing the flexible closure material to a receptacle. The separating step is accomplished by tearing the supplied flexible closure tape along its longitudinal length.

Patent CA-2097360-A1 (CA)
Title: Optical readers
Inventor: DVORKIS PAUL
IPC: G06K7/10
Filed: 1993-05-31
Abstract: IMPROVED OPTICAL READERS             Abstract of the Disclosure To read optically encoded information over a wide range of densities, the present invention provides a spacer system on the tip of an optical reader.   The optical reader may be a contact wand type device, for example  including  a  fixed  laser  emitter. Alternatively, the optical reader may be a moving spot scanner.   In either case, the emitter element of the optical  reader  produces  a  diverging beam of  light. During a reading operation,  the spacer contacts the object surface on which optically encoded indicia is formed.   The spacer selectively defines at least two different distances between the light emitter, or the focal  point  of  the  emitted beam of  light,  and the object surface.   Because of the beam divergence, the diameter of the beam at its point of impact on the object surface will be different for each of the two different  distances.    The  different  beam diameters provide the optical  reader with different  effective sensing spots for reading different density symbols. The  present  invention  also  incorporates  an  optical reader, typically a moving spot laser scanner, into a number  of  different  types  of  computer  data  input devices, such as the stylus of a digitizer table and a computer  "mouse."    In  one  such  integrated  terminal embodiment, the optical reader is combined with a touch sensitive display and data input device.

Patent CA-2116717-A1 (CA)
Inventor: CINQ-MARS PIERRE
IPC: A63B53/04
Filed: 1994-03-01
Abstract: Over the last twenty years numerous developments occurred in the domain of golf equipment. Of the main changes, the most important is the development and the commercial production of the metal  and  graphite  clubheads as  alternatives  to conventional wood driver and fairway woods. The objectives in replacing wood by stainless steel, steel and graphite were to further control the positioning of the center of gravity in the clubhead. At  that time, the objective was to improve the ball velocity and direction, the clubhead's construction has to be such that the center of gravity has to be the closest possible to the hitting point or better known as the sweet spot. Weight factor of the club is critical and has to be respected within grams.  The other main factor, mateial's distribution on the club head should be such to respond to the  rigidity  requirements  mostly  at  the  club  face peripheries. These two factors tend to be opposite when they are separately maximized in the clubhead's construction. Stainless steel, steel clubheads' construction are made of two separately cast hollow shells welded with  foam injected in the center hollow construction, as stiffning and vibration resistant material.  The weight factor together with the rigidity factor are the main detriment factors for stainless steel and steel clubheads; the hitting surface - sweet spots is made of thin wall and tend to shatter under the golf ball impact, thus affecting the ball's direction. Recently, new approaches have been taken to resolve this problem in casting a steel insert for the hitting part of the club or installing a graphite hitting surface insert in the front end of the club. Results are known to be mixed and are only partially exploiting the laws of physics that apply in the movement of hitting a golf ball.  The present invention of  metal matrix composites golf clubheads is based on the light weight of aluminium composites compared to stainless steel and steel (ratio 1:3), the strength,  stiffness, vibration and wear resistance of aluminium metal matrix composites.  Using aluminium metal matrix composites allows such  modifications to the interior design and construction of the golf clubhead giving a better control over the positioning of the center of gravity at the front end of the clubhead: hitting zone or sweet spot, an increase of the front wall thickness to avoid any shattering of the club face upon impact and a better distribution of the mass at the peripheries to obtain a better dynamic behaviour in the clubhead, thus leaving a lesser hollow interior surface for vibration at an equivalent weight to the stainless steel, steel or graphite clubheads. Increase thickness of the hitting surface, larger sweet spot, a reduced hollow surface maximize the use of the laws of physics that apply to the motion of hitting a golf ball.
