Patent CA-2052238-A1 (CA)
IPC: B62K21/06
Filed: 1991-09-25
Abstract: A steering bearing assembly is provided for connecting the front wheel and handle bars of a bicycle to the frame.  The assembly includes a steerer tube, connected to the front wheel and passing through a head tube on the frame.  Bearing assemblies on the upper and lower ends of the head tube allow the steerer tube to pivot within the head tube.  The upper bearing assembly has a first race connected to the head tube and a second race having a tapered contact surface.  Above the second race on the steerer tube is a compression ring having a gap so the ring can be compressed against the steerer tube.  The connector of a stem is located on the steerer tube above the compression ring.  The handle bars of the bicycle are connected to the stem.  An adjuster nut is threaded into the upper end of the steerer tube, exerting a downward force on the connector and the compression ring.  The second race compresses the compression ring, locking the upper bearing assembly in place on the steerer tube.  The connector is then clamped onto the steerer tube.

Abstract: A spatter shield is provided which is attached to a lower portion of the inner door of a dishwasher at a location above and inside the upper edge of the enclosure tub.   This shield includes a flange area for deflecting fluid splashed toward the dishwasher opening back into the tub when the door is closed.  A channel is provided which is shielded by the flange area for receiving run-off fluid from  the  flange  area  when  the  door  is  open  and  for discharging that run-off into the tub when the door  is closed.   The  shield  can  extend  horizontally  along  a substantial length of the door and is preferably attached to the door by way of a rib on the door which is received in a toothed slot of the shield.   The teeth within the slot permit the rib to be inserted relatively easily but resist withdrawal of the rib.  These teeth are preferably co-extruded with the  rest of the shield from a plastic composition that is relatively flexible with  respect  to the material forming rest of the shield.

Abstract: A system for measuring level of liquid material in a containment vessel that includes a hollow conduit composed of a first conduit section having an upper end coupled to a pressure sensor and a lower end disposed within the vessel.  A second conduit section is coupled to the lower end of the first conduit section and extends downwardly therefrom at least to a minimum material measurement level within the vessel.  The second conduit section has a vertical height coordinated with the maximum desired material measurement level within the vessel such that pressure of air captured within the first conduit section at such maximum material level prevents entry of the liquid material into the first conduit section.  The cross sectional area of air flow within the second conduit section is at least ten times, and preferably at least sixteen times, greater than the cross sectional area to air flow within the first conduit section.  Thus, the volume of air captured within the air column formed by the first and second conduit sections is minimized, thereby minimizing the effects of temperature-induced fluctuations of column air pressure.          On the other hand, liquid level within the air column remains at all times within the conduit section of larger diameter, thereby reducing the likelihood of clogging of the small-diameter conduit section due to sediments or the like carried by the liquid.

The flexible cover (26) may be formed as panels (A, B and C) having adjacent lengths of material (28) of differing optical densities.  The lengths (28) are arranged sequentially along the cover (26) and may be transparent, translucent or opaque.  Some of the lengths may have heat insulating and/or heat reflective properties and some may be foraminous to provide regions of different optical density and ventilation.  The longitudinal ends (30) of adjacent lengths (28) are joined by a seam.  Alternatively the flexible cover (26) may be formed from a single length of material having a different optical density along its length.
