Patent CA-2148574-A1 (CA)
Inventor: YENULIS GLENN
IPC: E21B33/06
Filed: 1992-01-29
Abstract: An improved rotary blowout preventer having a rotary housing rotably mounted within an outer housing and carrying an annular packer assembly hydraulically actuated by fluid circulated through the outer housing by hydraulic pumps.  An annular adapter is detachably and reattachably connected to an upper rim of the rotary housing.  The adapter has a tubular, elastomeric sleeve detachably and reattachably connected thereto that depends within the rotary housing adjacent the packer assembly.  A drill pipe is received within the sleeve and is sealably engaged thereby when the packer assembly is urged inwardly by the circulated hydraulic fluid.  The sleeve protects the packer assembly from wear and is easily replaced with other sleeves of like configuration.  The sleeve has a plurality of rigid grippers seated therein which extend flush with an inner surface thereof for gripping the drill pipe to facilitate concomitant rotation of the sleeve and rotary housing therewith.  The circulating pumps have a heat exchanger connected thereto for cooling the hydraulic fluid which reduces the internal temperature of the rotary blowout preventer to extend the operating life of various bearing and seal assemblies commonly found therein.  Filters are provided to remove foreign particulate matter dislodged from the outer casing by the circulating hydraulic fluid.

Title: Steering arrangement for wheeled conveyance
Inventor: HICKMAN ALAN TREVOR
IPC: A63C17/04
Filed: 1994-02-23
Abstract: A wheeled conveyance for use in leisure or sporting activities having a front steerable wheel (7) and two rear wheels (11). A user of the conveyance stands astride the conveyance on two spaced foot plates (10, 12) mounted respectively near the front wheel (7) and rear wheels (11). The front foot plate (12) is connected by cables (15) to the fork (6) of the conveyance carrying the front wheel (7) and is pivotally mounted to the frame (20) such that foot actuation by user operates through the cables (15) to steer the front wheel (7). Because of the provision of the pivotal foot plate (12), as well as steering the conveyance, it allows the user to execute additional bodily movements during movement over the ground such as those experienced when surfing in contrast to an ordinary skate board. In addition the construction allows the use of larger diameter wheels so that the conveyance can be deployed over rough terrain in contrast to known skate boards and can execute tighter turning circles than heretofore possible.

Title: Liquid dispenser for dispensing foam
Inventor: BANKS STEWART
IPC: B05B7/02
Filed: 1995-04-03
Abstract: There is disclosed a foaming de-vice for dispensing foam. The device in-cludes a collapsible liquid container (30) and a foam pump (36) attached to the con-tainer outlet. The foam pump includes two enclosures, the first being bonded in the throat of the container and the sec-ond being telescopingly received in the first. When assembled, the two enclosures define an air chamber (104) and a fluid chamber (50) each having outlets which merge by the foamer outlet. The fluid chamber (50) accepts liquid from the con-tainer (30), and when the second member is moved with respect to the first mem-ber, the fluid chamber (50) is pressurized to open an outlet valve (20), and air is si-multaneously expelled through the outlet. The liquid and air commingle as they pass through a wire, plastic or fabric mesh (84) thereby forming the foam. There is in-cluded a dispenser housing for releasably receiving the collapsible liquid container and foam pump. The dispenser includes a push button pivotally attached thereto which is coupled to the second enclosure so that as the push button is moved the pump is actuated.

Patent CA-2173063-A1 (CA)
Title: Headgear Accessory
Inventor: ARMENTA VINCENT N
IPC: A42B1/04
Filed: 1996-03-29
Abstract: A headgear accessory is adaptable to an existing cap, hat, hood, or other article worn on the head, to cover a hole or passage formed therein to provide for .the passage of the hair of the wearer therethrough. Using the present headgear accessory, a hole,may be placed in the headgear at a location comfortable for the passage of longer hair (e.g., ponytail, braid, etc.) therethrough, and the accessory sewn or otherwise secured to the headgear to provide a decorative closure for the hole. The accessory is preferably formed of a resilient, flexible material such as neoprene sheet, with a synthetic fabric overlay for additional strength and to provide a more attractive appearance. A series of slots are formed in the neoprene/fabric sheet, through which the wearer's hair is passed. The resilient nature of the sheet material biases the material to each side of each of the slots against the hair, thereby providing greater security for the headgear on the wearer's head and yet providing for ease of removal of the headgear. The periphery and edges of the slots of the accessory may be stitched for greater durability and to provide an attractive appearance, if desired. The accessory may be provided separately, or in combination with various types of hats, caps, hoods, and/or other headgear of virtually any type.
