Inventor: ERDEN DONALD L VAN
IPC: B25C1/04
Filed: 1996-07-30
Abstract: In a combustion-powered, fastener-driving tool with a combustion chamber, a piston chamber communicating with the combustion chamber, a driving piston movable within the piston chamber between an initial position and a terminal position, and a driving blade mounted to the driving piston so as to be conjointly movable with the driving piston, the driving piston, the driving blade, and the piston chamber are arranged so that combustion in the combustion chamber imparts energy to the driving piston and the driving blade so as to drive the driving piston and the driving blade from the initial position toward the terminal position with the driving blade preceding the driving piston, over a stroke having a length sufficient to enable the driving blade to transfer more than eight tenths of the maximum, transferable energy to a fastener engaged by the driving blade as the driving piston and the driving blade approach the terminal position.  The piston chamber has an inner, cylindrical wall.  The driving piston has an annular portion with an annular groove seating a piston ring or has two axially spaced, annular portions, at least one of which has an annular groove seating a piston ring engaging the inner, cylindrical wall.  The driving piston, the driving blade, and the piston chamber are arranged so that the driving piston and the driving blade are guided solely within the axial length of the driving piston, over at least substantially all of the stroke.

Title: Hierarchical Switch Support of Services for Subscribers Based on Organizational Membership
Inventor: ANDRUSKA DONALD LEE
IPC: H04Q3/00
Filed: 1996-09-10
Abstract: A telecommunication network includes first subscribers supported by a first local telecommunication switch. A first signal is received from the first switch at a second telecommunication switch disposed at a hierarchical level above the first switch.  The first signal indicates to the second switch that features based on organizational affiliation of the calling party are to be provided.   A second signal is received at the second switch from the first switch indicative of the identification of the calling party.  A record in a database coupled to the second switch is located in response to receiving the second signal; the location of the record being based on the identification of the calling party.  A group affiliation parameter stored in said record is identified; the group affiliation parameter defines one organization of which the calling party is a member.  The second switch transmits a call setup message to a third switch associated with a called party.  The call setup message includes the group affiliation parameter so that the calling party's membership in the one organization is available for further call processing.

Patent CA-2187468-A1 (CA)
Inventor: TARGOSZ EUGENE F
IPC: D06M23/10
Filed: 1996-10-09
Abstract: Compositions for removal of wrinkles in textile fabrics particularly including wool and silk, a primary active ingredient of the compositions being a cationic surfactant or surfactants, preferably based on low molecular weight vegetable oils.  A preferred solvent/carrier is selected to be high purity deionized water which exhibits synergism with the cationic surfactant and with relatively low concentrations of alcohols in the compositions, the anti-wrinkling action of the compositions occurring especially with exceptionally low concentrations of the cationic surfactant or surfactants.          The low concentrations of the cationic surfactants coupled with the low molecular weights of said surfactants reduce residues remaining on the textile fabrics and enable the compositions to demonstrate increased effectiveness on ordinary textile fabrics and extraordinary effectiveness and accept-ability on textile fabrics formed of natural fibers such as wool and silk.  The compositions of the invention can be applied to textile fabrics as a fine mist or by other methods of application and can particularly be used in a home environment without hazard to the fabric or the health and safety of a user.

Patent CA-2189399-A1 (CA)
Title: Catheter mapping system and method
Inventor: WITTKAMPF FREDERIK H M
IPC: A61B5/296
Filed: 1996-11-01
Abstract: A system and method are provided for catheter location mapping, and related procedures. Three substantially orthogonal alternating signals are applied through the patient, directed substantially toward the area of interest to be mapped, such as patient's heart. The currents are preferably constant current pulses, of a frequency and magnitude to avoid disruption with ECG recordings. A catheter is equipped with at least a measuring electrode, which for cardiac procedures is positioned at various locations either against the patient's heart wall, or within a coronary vein or artery. A voltage is sensed between the catheter tip and a reference electrode, preferably a surface electrode on the patient, which voltage signal has components corresponding to the three orthogonal applied current signals. Three processing channels are used to separate out the three components as x, y and z signals, from which calculations are made for determination of the three- dimensional location of the catheter tip within the body. An easy calibration procedure, which can be performed separately or during the mapping, is used to calibrate the system and provide the correlations between respective x, y and z sense signals and dimensional locations. The procedure is particularly applicable for catheter mapping prior to ablation, and for repositioning the catheter tip at precise locations for the desired ablations. The procedure is also applicable for other techniques where position must be remembered and re-found with accuracy, such as in mapping coronary stenosis and/or placing stents. Although the invention provides the greatest benefit in 3- dimensional applications, it is also useful for one and two dimensional applications.

Title: Fluid reaction device
Inventor: LINGMAN PHILIP T
IPC: F01C1/44
Filed: 1995-08-21
Abstract: A fluid reaction device (10) is provided having a rotor (90) with vanes (92) pivotably connected thereto. The device (10) includes an entrance (30) for elevated pressure fluid and an outlet (40) for discharge of the fluid after contacting the rotor (90). The elevated pressure fluid passes from the entrance (30), into a high pressure chamber (80). The high pressure chamber (80) is in contact with inlet ports (74) accessing a cylinder (72) within the device (10). The cylinder (72) supports the rotor (90) with a rotational axis (M) of the rotor (90) off center with respect to a central axis (N) of the cylinder (72). The elevated pressure fluid causes the rotor (90) and an attached output shaft (97) to rotate. The rotor (90) includes a trunk (24) with a plurality of posts (93) extending therefrom and with vanes (92) connected to the posts (93) through hinges (94). The vanes (92) can pivot from a first position collapsed against the trunk (24) to a second position spaced away from the trunk (24). The vanes (92) thus can contact a cylindrical wall (78) of the cylinder (72) while the rotor (90) rotates. Exhaust ports (76) are spaced from the inlet ports (74) and provide communication with a low pressure chamber (82) which exhausts low pressure fluid to the outlet (40).

Filed: 1997-10-30
Abstract: A method and apparatus for producing a single face corrugated web from an adhesively bonded liner and medium web without the use of a pressure roll nip where the liner web is joined to the medium web.  A heated bonding roll with a fluted outer surface carries the single face web around a circumferential portion sufficient to create a green bond in the glue lines before the web is removed from the roll.  The bonding roll may be internally heated or a steam chamber may be positioned around a portion of a lower bonding roll, such that the steam chamber introduces a supply of steam into contact with the single face web while the single face web is in contact with the outer circumference of the bonding roll.  An adjustable wrap arm places the freshly glued single face web in contact with the bonding roll and tension in the liner web is controlled to adjust the radial force applied to the glue lines.
