Title: Arrangement for reducing standby power losses in hydraulic valve controlsystems
Inventor: MCBURNETT JAMES ROBERT
IPC: F15B13/02
Filed: 1997-03-19
Abstract: In order to improve the efficiency of a dry valve system, a scavenge pump is employed when the system is operated in an idle or dry mode. The scavenge pump is connected to the output of an implement pump so as to reduce the discharge pressure of an implement pump in the system to the inlet pressure of the pump.

Title: Connector device with overvoltage protection
Inventor: HIRUMA YOSHIMASA
IPC: H01R13/66
Filed: 1997-05-05
Abstract: A connector device includes a main body having a plug section.  The main body accommodates therein two contact members, a bidirectional diode-thyristor, and a distal end portion of a signal-transmission cable connected with an external electronic equipment.  The two contact members are connected with two terminals of the thyristor and two conductor wires of the signal-transmission cable, to thereby obtain a modular plug with overvoltage protection.  By inserting the modular plug into a modular jack, the external electronic equipment is connected with a communication line.  If an overvoltage is applied to the communication line, the thyristor is rendered conductive to absorb the overvoltage, so that the electronic equipment is protected from the overvoltage.  In place of designing the connector plug to hold the distal end portion of the signal-transmission cable, the connector body may be formed with a socket section which receives an external modular plug, to thereby obtain a modular adapter with overvoltage protection which is used to connecting a modular plug with a modular jack.

IPC: A61G5/04
Filed: 1997-06-27
Abstract: A wheelchair incorporates a tilt mechanism with a center of gravity compensation by employing a rotary actuator. The actuator is secured to the underside of the seat and has an arm pivotally secured to the frame. A seat pivot axis is located on a movable member that allows the axis to shift from a rear portion of the wheelchair toward a front portion as the seat is tilted from its upright position to a tilted position. This assures that the center of gravity of the user is maintained within the wheelbase of the chair, i.e., compensates for center of gravity.

Title: Towed vehicle braking system
Inventor: DECKER DANIEL L SR
IPC: B60T17/22
Filed: 1997-09-15
Abstract: Towed vehicle braking systems which are flexible enough for use by rental agencies and provide good safety features use a compressor (15) to drive a fluid actuator (12) with a piston (11).

Patent CA-2217404-A1 (CA)
Inventor: BOGER HENRY WILLIAM
IPC: F16K5/06
Filed: 1997-10-06
Abstract: A ball valve assembly and method in which a ball valve is rotatable in a conduit section to selectively permit fluid flow through the bore to control the flow of the fluid through the conduit section. An insert is disposed in the valve bore and has a plurality of small-diameter passages and a large-diameter passage extending therethrough. The valve is rotated from its closed position to a first, partially-opened position where the small-diameter passages are in the flow path of the fluid to reduce the flow rate and the noise caused by the fluid flow. The valve can be rotated to a fully-opened position in which the large-diameter passage is in the flow path of the fluid to achieve relatively high flow rates. The insert forms an airfoil surface to prevent separation of the fluid as it passes through the large-diameter passage.

Patent CA-2219618-A1 (CA)
Inventor: ROBBINS EDWARD S III
IPC: A47G19/22
Filed: 1997-10-27
Abstract: A drinking cup having a body portion and a removably attached cover including an offset drinking spout and an offset vent aperture.  The drinking spout and the vent aperture are each surrounded by wall members which depend generally away from an interior surface of the cover.  An air inlet flow control valve is coupled to the wall member surrounding the vent aperture while a liquid outlet flow control valve is coupled to the wall member surrounding the spout. Each flow control valve includes a domed elastomeric member containing a slit allowing for passage of a selected fluid therethrough.  The domed portions are each surrounded by a generally circular isolating channel, and outside of each isolating channel is a perimetral portion for connecting the flow control valve to the depending wall portion of the cover.  Fluids passing through the slits achieve substantially only a one-way passage as the domed curvature substantially prevents any backflow.  Vacuum must be applied on the convex side of the domed portion for sufficient elastomeric displacement to allow a fluid to pass through the slit.  In the absence of such a vacuum, the sides of the slit are maintained in contiguous contact thereby preventing any transfer of liquid or air across the respective flow control valve. Coupling means are provided for coupling the flow control valves together, and may include handle portions integrally attached to the perimetral portion and including joining means for joining the handle portions together.

Title: Pneumatic tire, method of manufacturing a pneumatic tire, rubber composition, and vulcanized rubber composition
Inventor: NISHIKAWA TOMOHISA
IPC: B29D30/06
Filed: 1997-03-18
Abstract: A pneumatic tire which is used for a vehicle and obtained after a rubber material is formed by vulcanization. A cap portion (12A), which is an upper layer of a tread and directly contacts the road surface, is a foam rubber which includes innumerable elongated closed cells (24). The outer portion of the elongated closed cell (24) is coated by a resinous protective layer (26). During the vulcanization process of the tire, a resin whose viscosity is lower than that of a rubber matrix and a blowing agent which generates gas are kneaded with a rubber material so as to obtain a rubber composition. The rubber composition is formed in the shape of a band and adhered to a crown portion of a raw tire casing. The resin is melted by the heat of vulcanization and the viscosity of the resin is lower than that of the rubber matrix. The gas generated in the rubber moves toward and concentrates at the inner side of the resin. Accordingly, an elongated closed cell (24) whose outer portion is provided with the resinous protective layer (26) is formed.

Title: Solar cell system and method of establishing the system
Inventor: LUND-HANSEN KJELD BALSLEV
IPC: H02S20/00
Filed: 1996-05-30
Abstract: Solar cell systems are normally made as a number of panel plates sized typically 0,5-1 x 1 m, with associated mounting means for holding the plates in suitably inclined positions relative to a horizontal or vertical mounting base. According to the invention, these panel plates may advantageously be changed into a lamella-shaped structure, e.g. with a width of only 10-20 cm and, in return, with a much larger length dimension, whereby strips of a solar cell sheet material can be supported by already highly developed and inexpensive carrier systems, whether or not these also serve another purpose with respect to sun shading. A number of relevant advantages is obtained in using carrier laminae made of aluminium.

Title: A method of continuous production of lignocellulosic boards
Inventor: SJ DIN KJELL
IPC: B27N3/24
Filed: 1996-07-25
Abstract: A method for the continuous production of boards having a lignocellulosic fiber material wherein the material is broken up into particles and/or fibers that are dried, glued and formed and pressed to a finished board. The mat is pre-compressed while steam is introduced in such a limited amount during the pre-compression that the temperature of the fibrous mat increases to a value within an interval of 60-95 °Celsius. In this way, the spring back characteristics of the fiber mat is reduced so that its resistance to compression is reduced and the thickness can be reduced more in the pre-compression while the temperature is not so high to initiate a curing process.
