Title: Heat exchanger flow through tube supports
Inventor: CALANOG MARCIANO M
IPC: F28D7/16
Filed: 2003-01-22
Abstract: A tube support system for a heat exchanger that serves to replace the baffles present in typical shell-and-tube heat exchangers. A shell-and-tube heat exchanger employs helically coiled wires to form a support structure for the tubes contained within the heat exchanger shell. The elimination of baffles and the use of the coil support structure according to the present invention permits axial fluid flow for the shell side fluid and significantly minimizes fouling problems and tube damage resulting from flow-induced tube vibration.

Title: Method for producing paper machine clothing
Inventor: HANSEN ROBERT A
IPC: D21F1/10
Filed: 2001-10-03
Abstract: A papermaker's fabric is manufactured by spirally winding a laminated structure (16) in a plurality of turns. The laminated structure has a bottom layer (36) and a top layer (34), both of which are strips having a common width. The bottom layer (36) and the top layer (34) are laminated to one another in a transversely offset manner, so that an unlaminated portion of the bottom layer (36) is along one lateral edge of the laminated structure and an unlaminated portion of the top layer (34) is along the other lateral edge.  When the laminated structure is spirally wound, the unlaminated portion of the top layer in one turn overlies the unlaminated portion of the bottom layer in an adjacent turn. These are joined to one another to form the papermaker's fabric from the spirally wound structure.

Abstract: The present invention is a portable outrigger designed especially for canoes. The outrigger consists of a supporting frame and a canoe shaped pontoon. The frame of the outrigger provides a 7ft × 3ft.4"platform, made up of 7 cross support panels, This platform extends horizontally out to one side of the canoe and can be used for the left side or right side. The rig can be fitted with a hanging cargo net under the platform, (the extended section). This design of outrigger also supports a one person tent and fly assembly. The outrider is telescopic. When the tent and fly assembly are not in use the platform section can be retracted or extended. To do this, flip one cross petrel onto another, next unlock the Middle Support Lock Bar to allow the support poles to slide in or out. There are only 4 bolts used, they attach the main lock panel to the pontoon.  The rest of the assembly uses fitted straps to fasten the cross panels to the outrigger and 2 straps to secure the outrigger to the canoe.      The main attaching components are 4 molded foam blocks. They are the structural connecting joints. This is where this main support structure poles cross the canoe gunnels. They measure 4×5×7 inches. There is a 2×1 3/4×7 groove along the middle bottoms of the connector blocks for the canoe rail to fit onto. There is a 2 3/4 round hole for the main support structure poles to slide into from the sides.  This hole crosses above the canoe gunnels with a 3/4 " inch of foam between the main support structure poles and the rails.     The entire assembly can be easy collapsed into a carry bag. The pontoon is carried as a separate piece. The smaller components can be stored inside the storage compartments in the pontoon. No tools are needed.

Title: Acoustic source using a shaftless electrical hammer
Inventor: CHANG CHUNG
IPC: G01V1/52
Filed: 2003-04-24
Abstract: The present invention discloses a shaftless acoustic source having a solenoid, a bullet and driving electronics. The bullet, which is positioned inside the solenoid's coil, can be accelerated by a magnetic force generated when a current pulse is applied to the coil. Acoustic energies are generated upon the impact of the bullet with an object, such as a borehole wall. This impact force can be described by the Hertzian Contact Theory (also referred to herein as Hertzian Theory) as a point of normal force with a time function similar to a half period sine function. A retraction means may be used to retract the bullet back into the solenoid after firing.

Title: Concentres stabilises de revelateur de film simple a base de cd-4

Filed: 2002-02-06
Abstract: Les concentrés de solution d'entretien de révélateurs photographiques comprenant des révélateurs plus réactifs tels que la 4 (N-éthyl-N-2-hydroxyéthyl)-2-méthylphénylènediamine (CD-4), ces concentrés subissent une oxydation rapide et, en conséquence, possèdent une stabilité de conservation réduite. On a découvert que les dérivés de type hydroxylamine alors qu'ils se sont avérés utiles en tant que classe d'antioxydants pour stabiliser les solutions d'entretien des révélateurs photographiques, confèrent généralement une stabilité de conservation insuffisante au révélateur à base de CD-4, ou interfèrent avec une <= performance de révélateur satisfaisante >=. De façon surprenante, on a découvert que la stabilité de conservation de concentrés de solutions d'entretiens comprenant des révélateurs photographiques à base de CD-4 peut être allongée pour des périodes de 2 ans ou plus, et lesdits concentrés fournissent en outre une performance de révélateur satisfaisante lorsque l'antioxydant d'hydroxylamine comprend au moins une N, N-bis (2-sulfoéthyl) hydroxylamine (SEHA) ou un sel de cette dernière.

Title: Active seat suspension control system
Inventor: BREMNER RONALD DEAN
IPC: B60N2/00
Filed: 2003-11-06
Abstract: A suspension system supports a seat with respect to a base mounted on a frame of a vehicle. The system includes a hydraulic actuator coupled between the seat and the base. A single accelerometer is attached to the base and generates a base acceleration signal in response to motion of the base. A control unit actively controls the hydraulic actuator as a function of the base acceleration signal.  The control unit generates a base velocity signal by integrating the base acceleration signal, generates a seat position signal representing a position of the seat relative to the base, generates a seat position error signal representing a difference between a desired position and the seat position signal, and generates a command signal as a function of the velocity signal and of the position error signal. The control unit controls the actuator by applying the command signal thereto.
