Patent CA-2392701-A1 (CA)
Inventor: IVINSON EDWARD L
IPC: E04F15/10
Filed: 2002-07-09
Abstract: A deck including a panel, a retainer and a fastener. The panel includes a flange having an aperture therein. The retainer includes an upper leg and a lower leg embracing the flange therebetween, with the lower leg having a fastener receiving opening. The fastener is for attaching the panel to structural framework, with the fastener including a shoulder. The fastener extends through the aperture of the flange and the opening of the lower leg of the retainer. The shoulder extends through the aperture in the flange and abuts against the lower leg of the retainer to secure the retainer. Furthermore, the shoulder is sufficiently tall as to prevent the fastener from tightly clamping the flange. Additionally, the flange embraced between the upper leg and the lower leg of the retainer is adapted to expand between the upper leg and the lower leg. Therefore, thermal expansion of the panel is accommodated.

Title: Roller conveying apparatus
Inventor: RANSIL MATTHEW J
IPC: B65G67/20
Filed: 2001-02-16
Abstract: A track assembly comprises an inner channel member, an outer channel member and a top plate, through which load bearing rollers selectively protrude. An inflatable air bag is between the inner and outer channels for raising and lowering the inner channel. An air line fitting at one air bag end passes through the outer channel member side wall to fix the air bag end longitudinally in place.

Title: Bone plate system
Inventor: BOLHOFNER BRETT R
IPC: A61B17/58
Filed: 2000-09-06
Abstract: The present invention relates to a bone plating system and method for fracture fixation of bone.

The bone plate (30; 50; 80) has locking holes (36; 56; 86) with threads (40) and non-locking holes (38; 58; 88). The locking screws (20) have a shaft (26) with a thread for engaging bone and a head (22) with a thread (24) configured and dimensioned to mate with the thread (40) of the locking holes (36; 56; 86).  The non-locking screws (10) have a thread for engaging bone and a non-threaded head (12). Both the locking and non-locking screws (20; 10) remain seated in their respective holes (36; 56; 86; 38; 58; 88) for substantially as long as the bone plate (30; 50; 80) is implanted. The non-locking screws (10) compress the bone plate (30; 50; 80) against the bone and hold fracture reduction while the locking screws (20) are secured to the plate at a fixed angular relationship. The mixed fixation achieved by this bone plating system and method is particularly useful for treatment of per-articular fractures.

Abstract: There is provided a premium acquisition game system which, utilizing a communication network, allows each player to virtually enjoy such a premium acquisition game as in an amusement center or the like by use of a personal computer or the like, and further ensures that an acquired premium is delivered to the player without fail. When a host computer (2) coupled throu gh a communication network (6) to a multitude of player terminals (4) receives the notifications of game start from the respective terminals (4), it retrieves, from a database, information on the actual premium stock, and determines, based on the retrieved information, the number of virtual premiu ms allocatable to for the terminals (4). The host computer (2) then allocates virtual premiums the actual allocation number of which is a predetermined number equal to or less than the number of the allocatable virtual premiums,  and then issues a permission of the game start to a respective terminal (4).  The host computer (2) subtracts the actual allocation number from the number  of the allocatable virtual premiums. When the host computer (2) receives the  notification of a game over from a respective terminal (4), it registers in the database the number of acquired virtual premiums, and adds the number of  virtual premiums which have not been acquired to the number of allocatable virtual premiums, thereby providing the number of the next alocatable virtua l premiums.

Title: Gas separating intake for progressing cavity pumps
Inventor: PROCTOR BRUCE ERWIN
IPC: E21B43/12
Filed: 2003-04-17
Abstract: A downhole pump assembly is suspended by tubing in a well. The pump assembly has a separator attached below a progressing cavity pump with a flexible shaft to accommodate the concentric path of the shaft of the separator and the eccentric path of the rotor of the pump. Vanes on the shaft of the separator use centrifugal force to separate the heavier liquids from the lighter gases in the well fluids.
