Patent CA-2026623-A1 (CA)
Inventor: SCANLON ROBERT M
IPC: B21C35/02
Filed: 1990-10-01
Abstract: An extrusion puller which comprises an upper jaw, a lower jaw, and means for mounting the upper and lower jaw relative  to  each  other.    The  upper  jaw  comprises  a plurality of jaw fingers with radially extending gripping teeth circumferentially spaced around the bottom portion of the tooth wherein the attack angle between teeth and the spacing angle between adjacent teeth is selected so that substantially full penetration of at least one of the gripping teeth into the workpiece is achieved without interference  from  an adjacent tooth.    The  lower  jaw comprises a serrated upper surface comprising a semi-circular scalloped configuration of a plurality of peaks and valleys.  The combination of the upper jaw and lower jaw configuration allows for increased gripping strength to be exerted on the workpiece and thereby avoid defects within the extruded workpiece.

Title: Stickless catheter with manual shut-off valve
Inventor: LEMIEUX FRANCIS P
IPC: A61M39/00
Filed: 1991-04-30
Abstract: A catheter device is described with a safety needle guard that covers and protects the needle after use of the device. The device includes a semi-tubular needle housing containing a flash chamber with a hollow needle extending from the distal end of the flash chamber. A tubular needle guard concentrically fits and slides within the needle housing. The needle guard has a longitudinal slot through which the mounting base of the flash chamber passes as the guard slides within the housing. The top of the semi-tubular housing is open so that a user may access the top of the tubular needle guard with a finger to urge the needle guard to an extended position from the distal end of the housing and in a surrounding position about the needle. The proximal end or hose of the needle guard detaches for the needle housing and has a luer fitting for an infusion set.

Title: Communications device with voice recognition and movable element control interface
Inventor: METROKA MICHAEL P
IPC: H01H3/16
Filed: 1990-11-01
Abstract: A portable radiotelephone with an integral voice recognition circuit is disclosed. Control of the voice recognition circuit is achieved with a foldable housing element (104) which, in a closed position, covers an external keypad (110) and control buttons. When the foldable housing element (104) is in an open position, the portable radiotelephone is placed in an off-hook condition, the voioe recognition circuit (432) is activated, and the acoustic transducers (320, 424) are coupled to the voice recognition circuit (432). When the foldable element (104) is in a closed position, the portable radiotelephone is placed in an on-hook condition, the voice recognition circuit (432) is deactivated, and the electroacoustic transducers (320, 424) are coupled to the radiotelephone. A rapid closing and opening of the foldable element (104) results in the voice recognition circuit (432) being deactivated while the portable radiotelephone remains in the off-hook condition.

Title: Logical partitioning of a redundant array storage system
Inventor: STALLMO DAVID C
IPC: G11B20/18
Filed: 1991-11-01
Abstract: A redundant array storage system that can be configured as a RAID 1, 3, 4, or 5 system, or any combination of these configurations. The invention comprises a configuration data structure for addressing a redundant array storage system, and a method for configuring a redundant array storage system during an initialization process. The redundant array storage system comprises a set of physical storage units which are accessible in terms of block numbers. The physical storage units are each configured as one or more logical storage units. Each logical storage unit is addressed in terms of a channel number, storage unit number, starting block number, offset number, and number of blocks to be transferred. Once logical storage units are defined, logical volumes are defined as one or more logical storage units, each logical volume having a depth characteristic. After the logical volumes are defined, redundancy groups are defined as one or more logical volumes. A redundancy level is specified for each redundancy group. The redundancy level may be none, one, or two. Logical volumes are addressed by a host CPU by volume number, initial block number, and number of blocks to be transferred. The host CPU also specifies a READ or WRITE operation. The specified volume number, initial block number, and number of blocks to be transferred are then translated into a corresponding channel number, storage unit number, starting block number, offset number, and number of blocks to be transferred. With the present invention, it is possible for a logical volume to span across physical storage units ("vertical partitioning"), comprise only a portion of each such physical storage unit ("horizontal partitioning"), and have definable depth and redundancy characteristics.

IPC: E21B19/14
Filed: 1991-11-28
Abstract: ROD HANDLER APPARATUS                   ABSTRACT OF THE DISCLOSURE      An extendable boom assembly is mounted on a platform or a base for longitudinally pivotally moving a drill rod between a rod rack and a drill rig in a position in alignment with the drill string axis regardless of whether the drilling direction is vertical or is angularly relative to the vertical direction.          The boom assembly is mounted for pivotal movement with the track assembly and transverse movement relative thereto, the track assembly being mounted on a drill rig platform. The upper end of the boom assembly mounts a jaw assembly for releaseably gripping a drill rod, the jaw assembly being mounted for limited pivotal movement about a horizontal axis and is of a design not requiring the rods being in a particular spaced relationship relative to one another. The gripping assembly jaws and the limited pivotal movement results in the rod to be transferred being pivoted to a position parallel to the main boom arm central axis as the rod is being clampingly engaged and moved away from the rod stack.  The controls are located at a location away from the path of movement of the clamped drill rod.
