Patent CA-2158190-A1 (CA)
Title: Reduced friction screw
Inventor: HOLLANDER ANDREW A
IPC: F16B25/00
Filed: 1995-09-13
Abstract: A reduced-friction screw is described. The screw requires less turning torque than a conventional screw to drive it into a workpiece. The shaft of the screw has a reduced-thickness thread that produces less sliding friction than a conventional screw having thread of the same depth and pitch. In addition, the holding ability of the reduced-friction screw is substantially the same as a conventional screw having thread of the same pitch and depth. Another embodiment contains a shaft having a reduced diameter, to further reduce sliding friction. Yet another embodiment contains a segmented, reduced-thickness thread that resists removal and loosening when the workpiece is subject to twisting, vibration, or warping. To prevent loosening of the reduced-friction screw, the bottom of the screw head may contain protrusions to increase the frictional contact of the head with the workpiece.

Patent CA-2159568-A1 (CA)
Inventor: BUTTRAM JONATHAN DAVID
IPC: G01N29/24
Filed: 1995-09-29
Abstract: A method of examining a ductile iron casting to determine a  percent  of  nodularity  present  in  the  casting  uses  an electromagnetic acoustic transducer (EMAT) system to determine a time-of-flight of an ultrasonic shear wave pulse transmitted through the  casting  at  a  selected  location,  from which  a velocity of  sound in the casting can be determined.   The ultrasonic shear wave pulse created and sent through the casting experiences several internal reflections within the casting, and the absolute delay time for both second, TDELAY1, and third, TDELAY2, multiple reflections are used to determine the time,  TDELTA, required for the ultrasonic pulse to travel through twice the thickness, t, of the casting at said location.  The velocity, VSHEAR, of the ultrasonic shear wave pulse through the casting is calculated from TDELTA and a measurement of the thickness, t, of the casting at the location being inspected.   The percent of nodularity of the casting is determined from a pre-established relationship between the calculated shear wave velocity, VSHEAR, and the percent of nodularity for ductile cast iron.
Patent CA-2161720-A1 (CA)
Title: Snow Gun for Making Artificial Snow
Inventor: MCKINNEY VERNON LORNE
IPC: F25C3/04
Filed: 1995-10-30
Abstract: In a snow gun, each of air and water are discharged through V-jet nozzles in the form of generally flat and V-shaped jets or sprays. The nozzles are spacially positioned and angled so that the air jet intersects the water spray along a line of intersection where they are of equal width. This provides efficient atomization of the water with the result that snow can be made at milder freezing temperature. In another aspect, a flanged connection, having dual sealed openings for passage therethrough of pressurized air and water streams, is provided to join the gun and its supporting tower. In another aspect, the snow gun has a plurality of associated intersecting water sprays and air jets which are oriented to produce non-converging plumes.
Patent CA-2161759-A1 (CA)
Title: Method of yarding logs by introducing slack into a mono-cable system
Inventor: DAHLSTROM GALE E
IPC: B61B11/00
Filed: 1995-10-30
Abstract: A method and apparatus for yarding logs by introducing slack is provided for use with a mono-cable system having a continuous loop of cable strung through a logging area along a path that the harvested timber is conveyed. The invention includes advancing the mono-cable system along the path of the mono-cable system until a length of cable not being used to secure a log is available. Slack is then created in the cable of the mono-cable system, after which the cable is transported to a log located on either side and distant from the path. The choker is then secured to the log, and the hook of the choker is secured to the cable. The slack of the cable is then eliminated, such that the secured log is retrieved from its felled position distant from the path to a position adjacent the path. The cable is then advanced such that the hook of the choker is caught on a stopper of the mono-cable system, and the log is moved along the path to a transport location from which the log is removed from the logging area. The use of slack in the mono-cable system provides superior selective harvesting of trees at a logging site, reduces the labor required for retrieving such logs, increases the capacity of the mono-cable system, and reduces dangers heretofore inherent in conventional mono-cable systems caused by the height and constant tension required in the cable, while retaining the advantages of mono-cable systems over conventional line systems.

Filed: 1995-11-28
Abstract: A hinge structure of a spectacle frame has bearings  formed  at  the  ends  of  end  pieces  provided outside a pair of lenses or outside the rims supporting the lenses,  pivotally rotatable shafts at the tips of a pair  of temples  are pivotally rotatably connected with the bearings,  a compressed elastic means,  being provided around  the  pivotally  rotatable  shaft  exposed  in  the recess between the flange and the support face,  to give pressure to the bearing for keeping the sliding face of the temple in slidable contact with the sliding face of the bearing.   The hinge structure of a spectacle frame overcomes  the  disadvantages  of  the  conventional  hinge structure; that is functionally excellent because of easy assembling,  needlessness  of  complicated  adjustment,  and capability to keep the temple turning torque constant for a long time; and that is also excellent in appearance and design.
Patent CA-2164240-A1 (CA)
Title: Modular toy building system
Inventor: HARTMAN DAVID
IPC: A63H33/06
Filed: 1995-12-01
Abstract: The modular toy building system uses extruded foam rods which cooperate with foam cross connectors designed to receive up to four rods.  Each cross connector includes two connecting sleeves or tubes of a length for receiving and securing a foam rod either end thereof while leaving a central port unobstructed by the rods.  One sleeve has been deformed and inserted through the port of a second sleeve and positioned such that the ports overlap.  This produces a stable cross connector for cooperating and releasably receiving a foam rod in each end of a sleeve.  Preferably, sleeves which cooperate to form a cross connector have a securing gap passing axially through the sleeves, which gap forms part of the central port of each sleeve.  This gap can receive a pinning member joining two or more stacked connectors.  Preferably, the central port of each sleeve is oval.
