Abstract: A pneumatic mechanism  for the application of uniform pressure to a mechanically adjustable spindle.  The mechanism includes a support shelf with a double-acting piston attached at its non-pressure end to the support shelf.  A cylinder receives the piston for telescopingly sliding movement of the piston relative to the cylinder.  A lifting stop rod is connected to the pressure end of the piston and an externally threaded tube engages the pressure end of the piston and telescopingly receives the lifting stop rod.  A worm wheel engages the threaded tube and a worm gear engages the worm wheel.  A hand wheel is connected to the worm gear for rotating the worm gear and the worm wheel.  An adjustable connection is provided between the lifting stop rod and the threaded tube permitting limited stop movement of the lifting stop rod by the piston relative to the threaded tube. Air ports for directing pressurized air against the bottom end of the piston to lift the piston and the lifting stop rod relative to the threaded tube and against the upper end of the piston to return the piston to its lowered position are provided in the cylinder.

Abstract: A Mail Generation Computer (MGC) is connected to a Local Area Network (LAN) at a customer site having a mail generation facility.  A desktop PC on theLAN, under user control, accesses the MGC and submits a mail job to the MGC via the LAN. The MGC responds to the request and calls various mail piece generationmodules needed to implement the request, thus freeing the user's equipment for other uses. The invention includes a job coordinator module for the MGC, to call, run and coordinate the various modules. The system embodied in the server thus allows any user at the customer site to submit a job to a process implemented on the LAN, which generates a finished mail piece or pieces, thus freeing the user fromcontrol over each portion of the mail generator process and similarly freeing the user's equipment for implementing other tasks.

Abstract: A magnetostrictive linear displacement transducer includes an elongated member of a material with a large magnetostriction coefficient. There is a coil and a pulse driver for magnetizing the member to cause a detectable magnetostrictive effect for short discrete periods of time. A magnet is movable along the path adjacent the member and is capable of magnetizing a localized portion of the member adjacent the magnet efficiently to cause an alteration in the magnetostrictive effect in the localized portion in concert with the pulse driver and the coil. There is a piezoelectric device at one end for detecting axial strain pulses propagated along the member caused by the magnetostrictive effect. There is a comparator for measuring time lags between initiation of each separate discrete period of time and detection of a corresponding strain pulses by the piezoelectric device and thereby a position of the magnet along the path.

Title: Amortisseur de vagues pour structures flottantes
Inventor: OLSEN FRED
IPC: B63B39/08
Filed: 1996-11-26
Granted: 2008-04-01
Abstract: La présente invention concerne un système amortisseur de la composante de déplacement vertical, dû aux vagues, d'une structure flottante. L'amortisseur dépasse vers le bas, en forme de jupe, le fond de la structure flottante (11) et il est constitué par plusieurs canaux (47) sensiblement horizontaux qui convergent depuis une ouverture d'entrée (27, 28, 36, 37, 38) jusqu'à une ouverture de sortie (16, 46) qui s'écarte de la structure flottante (11). Quand cette dernière descend, l'eau est forcée à passer depuis le bas par les canaux (47) et elle crée un effet de jet qui produit un effet d'amortissement sur le déplacement vertical de la structure. L'amortisseur peut aussi être réalisé sous la forme d'une jupe, sur la structure flottante, dépassant vers l'extérieur, et être constitué par plusieurs canaux (17), avec un certain nombre de premiers passages sensiblement verticaux (27, 28) qui se rejoignent pour former un certain nombre de deuxièmes passages (29) qui sont au moins sensiblement horizontaux, forçant ainsi l'eau à passer d'un sens de déplacement sensiblement vertical, dans les premiers passages (27, 28), à un sens horizontal dans les deuxièmes passages (29), pendant une partie du passage à travers l'amortisseur (12). Il est possible de combiner les deux amortisseurs, l'amortisseur (12) étant situé immédiatement au-dessus de l'amortisseur (13).

Abstract: A self-biasing magnetostrictive element (10) for use in a magnetomechanical EAS marker is a strip of amorphous alloy material distributed throughout the bulk of the amorphous alloy strip. The crystalline particles (12) are magnetized to bias the amorphous alloy strip (14) to resonate in response to an interrogation signal. The crystalline particles (12) are formed by heat-treating the amorphous alloy strip (14) at a temperature above the Curie temperature of the amorphous alloy in the presence of a longitudinal magnetic field. The alloy strip (14) is then cross-field annealed at a temperature below the Curie temperature of the amorphous alloy to form a transverse anisotropy in the amorphous bulk of the alloy strip (14). A preferred alloy composition includes iron, cobalt, niobium, copper, boron and silicon.

Abstract: A method and apparatus for molding the hulls of vessels comprises a plurality of individual starboard base panels, starboard side panels, port base panels and port side panels, interconnected in a number of respective first panel groups and second panel groups, which groups are then connected side-by-side along the length of the vessel hull to be formed. The first panel groups are longitudinally spaced from one another and carried by adjustable vertical supports, whereas the second panel groups are removably mounted in between adjacent first panel groups to form a continuous negative mold surface against which the vessel hull can be constructed. After the hull has been formed, the second panel groups are removed while the first panel groups remain in place, a number of trolley devices are positioned beneath the hull in the spaces vacated by the second panel groups, and then the vertical supports are operated to lower the hull onto the trolley devices at which time the first panel groups can be disassembled thus allowing the hull to be transported on the trolley devices.

Title: Single energizer face seal for rock bits with floating journal bearings
Inventor: BURR BRUCE HAWLEY
IPC: F16C33/74
Filed: 1999-12-13
Granted: 2007-01-23
Abstract: The present invention is a self adjusting, volume balanced, single energizer rigid face seal for rolling cutter drill bits with floating journal bearings. Volume balancing is accomplished by utilizing a floating static seal between the rigid face seal ring and the bearing shaft. This floating static seal ring is moved axially within a annular groove by the volume pulses caused by the axial play of the cutter when in operation.  At one end of the annular groove the geometry of the rigid seal ring and bearing shaft are set such that the seal assembly achieves volume balance when the bearing is running on its OD. If the bearing is running on its OD, the floating static seal will move from where ever it is in the annular groove by the volume pulses until it reaches the balance volume position.
