Patent CA-2181284-A1 (CA)
Inventor: GOLDRING HAROLD B
IPC: A47F1/00
Filed: 1996-07-16
Abstract: The disclosure is of a gated display rack for dispensing card-mounted products and for reducing pilferage therefrom. An anti-sweeper device predeterminedly  spaced  from the  front  of  the dispensing hooks, which includes a pair of positionable side plates and a gate, is attached to the pair of fixed side plates. The gate is positionable between an on-sale position and a loading position, and the gate, when in the on-sale position, is aligned with the front of each dispensing hooks so as to cover a portion of the product card and inhibit removal of the card-mounted product. Also, when the gate is in the on-sale position, because the spacing between the gate and the front of the dispensing hooks is limited, the product cards may only be dispensed one or two at a time. With the gated display rack, a user removes a product by grasping a product card and exerting a downward force thereon. The flexed dispensing hook exposes the previously covered portion of the product card; and, the grasped product card is dispensed by the user moving the card along the dispensing hook and removing the card from the then exposed portion.

Title: Method of making liquid crystal composite
Inventor: REAMEY ROBERT H
IPC: C08L101/00
Filed: 1995-03-22
Abstract: A method is described for making a liquid crystal composite in which droplets of a liquid crystal material are dispersed in a matrix material.  An encapsulating material at least partially separates the liquid crystal from the matrix material.  This construction permits the matrix material to be selected on the basis of its processing and environmental properties and the encapsulating material to be selected on the basis of its emulsifying ability and orientational interactions with liquid crystal material.  Light valves made from such a composite exhibit improved electro-optical properties.
Patent CA-2187218-A1 (CA)
Inventor: BROWN ALLAN E
IPC: H05B41/04
Filed: 1996-01-23
Abstract: L'invention concerne un système de circuit pour allumer une lampe à décharge haute intensité sous la forme d'impulsions d'allumage fournies à la lampe avant et sensiblement pendant toute la durée d'incandescence de la lampe. L'allumeur présent dans le circuit comprend un dispositif bilatéral de commutation du type SIDAC ayant une tension d'amorçage correspondant à la tension de la lampe lorsque la lampe est en mode d'incandescence. Le système de circuit évite sensiblement que la lampe reste dans son mode incandescent pendant une durée de temps prolongée, ce qui minimise la possibilité d'une destruction de la lampe consécutive à une détérioration des électrodes de la lampe.

Patent CA-2194104-A1 (CA)
Inventor: DITKA MICHAEL P
IPC: F16B19/00
Filed: 1996-12-30
Abstract: A depth-insensitive concrete  fastener system is provided for securing roofing insulation materials to concrete roofing  or  decking.    The  concrete  roofing  or  decking substructure is provided with a pre-drilled hole or bore having a predetermined diametrical extent.   An anchor bolt fastener comprises a head portion, a pointed tip portion and a shank portion interconnecting the head and tip portions. The shank portion has a first relatively smooth shank portion disposed adjacent to the head portion and extending toward the tip portion and a second ribbed portion disposed adjacent to the tip portion and having an axial extent which is only a fractional portion of the entire axial extent of the fastener. The diametrical extent of the first smooth shank portion is less than that of the pre-drilled hole or bore defined within the concrete substructure, whereas the diametrical extent of the  second  ribbed  shank  portion  is  greater  than  the diametrical extent of the pre-drilled hole or bore defined within the concrete substructure.  Therefore, when the anchor bolt fastener is impactly driven into the pre-drilled hole or bore of the concrete substructure, an interference or friction fit is defined between the anchor bolt fastener and interior sidewalls of the concrete substructure defining the pre-drilled hole or bore only along the axial extent of the second ribbed shank portion of the bolt fastener.  Consequently, the fastener  system  is  rendered  depth-insensitive  in that regardless of the depth to which the anchor bolt fastener is driven into the concrete substructure, the installation force does not increase beyond a predetermined limit.  A roofing washer element may be pre-assembled upon the anchor bolt fastener as a result of being captured between the head and second ribbed shank portions of the bolt fastener.

IPC: B60K7/00
Filed: 1997-01-15
Abstract: A drive system for a vertical mast personnel lift uses a pair of rear wheels that are fixed in an axial direction of a base portion of the personnel lift. When an operator input to make a turn is received, DC motors respectively connected to the right and left rear wheels are rotated at a different rate. Neither the front wheels nor the rear wheels are steered during the turning movement. The front wheels are configured as caster wheels, which are free to turn in any direction. In order to rotate the personnel lift about its central axis, the right rear wheel is rotated at a first rate in a first direction, and the left rear wheel is rotated at the first rate in a second direction opposite the first direction.
