Title: Drywall Tape
Inventor: STOUGH RONALD A
IPC: C09J7/29
Filed: 1995-08-24
Abstract: To assist in rapid taping of seams between adjacent drywall units (24), a tape (20) is provided in rolls (22). The tape (20) has a first layer of flexible paper material with an inwardly facing pressure sensitive adhesive coating thereon. A second layer of reinforcing woven fiber material overlies the first layer. A third layer of flexible material overlies the woven fiber material to encapsulate the fiber material between the first layer and the second layer.  The third layer has an outwardly facing release coating such that the first layer adhesive will releasably engage the third layer for maunal separation of the tape (20) when rolled upon itself. The adhesive is formulated to maintain adhesion even when wetted by an overlying layer of drywall mud. Furthermore, the release coating on the third layer accepts and allows the adherence of drywall mud. The tape (20) may be used in fire wall applications. Perforations may be provided in the tape to facilitate adhesion.

Patent CA-2202534-A1 (CA)
Inventor: BYTZEK KLAUS
IPC: F16F15/12
Filed: 1995-10-16
Abstract: A crankshaft decoupler (10) has a mounting hub (12), a pulley (14) rotatably mounted on the mounting hub (12), an annular carrier (26) mounted within said pulley (14), a biasing device (38) mounted therebetween, and a one way clutch (40) mounted between the annular carrier (26) and the pulley (14). The biasing device (38) cushions the belt drive from crankshaft impulses and lowers the angular resonant frequency of the belt system. The one way clutch (40) prevents sudden reversal of the belt tension in the drive due to start/stop of the engine or sudden deceleration of the engine and prevents momentary reverse slip belt squeal as a result of the tensioners' inadequate output for the reverse mode. The one way clutch (40) limits the maximum amount of torque which may be transmitted preventing belt slippage during momentary overload.

Title: Manhole adjusting extension member
Inventor: WIEDRICH DWIGHT G
IPC: E02D29/12
Filed: 1997-05-29
Abstract: A molded plastic extension member for use in increasing the height of manholes, or catch basins when surfacing or resurfacing a roadway. The extension member may be formed having a sloping upper planar support surface to thereby adjust the angle of the catch basin support frame or the manhole cover support frame. An outer surface of the extension member includes indicia that allows the user to align the slope of the upper planar support surface parallel with the roadway surface. When several sloped extension members are stacked, the indicia may be used to create a complex angle of slope relative to the underlying base members vertical axis. The extension member includes a pocket adaptable for receiving and retaining mortar between two stacked extensions. Planar surfaces may extend from both the upper and lower edge of the extension member, thereby providing support and added stacking surface for the stacked extension members. The extension member also includes a tapered shoulder that interlocks with either the manhole cone, the catch basin cone, or with other stackable angled plastic members.

Patent CA-2233720-A1 (CA)
Title: Optically variable surface pattern
Inventor: TOMPKIN WAYNE ROBERT
IPC: B42D15/10
Filed: 1996-11-20
Abstract: An optically variable surface pattern (1) includes at least one representation of graphic configuration. Surface portions (3, 4, 5) of a predetermined kind are associated with each representation. Upon being illuminated with visible light the representations are visible in the form of images comprising comparatively light and dark points at different viewing directions. The surface portions (3, 4) associated with light points of at least one of the representations, have grating structures with a number of lines of less than 250 lines per millimetre so that many diffraction orders occur in the visible range. The profile shapes of the grating structures are so selected that a maximum possible proportion of the diffracted light is diffracted into higher diffraction orders. That provides that the corresponding representation appears achromatically. So that in addition the ratio between the light which is diffracted into positive diffraction orders and the light which is diffracted into negative diffraction orders is as great as possible, grating structures with an asymmetrical profile shape and in particular a sawtooth profile shape are to be used.

A passageway extends from the tip to a fitting outside the container which can be connected to a vacuum source such as a powder pump to draw in the powder coating material.  The fluidized powder is then carried to a spray gun for powder coating an object.  A second passageway may be carried within the shaft and extend from an opening within the container to a fitting outside the container to carry a pressurized gas into the container.  The container may be placed on a vibrating tilted platform to agitate the powder coating material.
