Title: Overfill preventing valve
Inventor: NITCHKE DAVID EARL
IPC: F16K1/30
Filed: 1998-07-28
Abstract: An overfill preventing valve is adapted to be operatively interposed in a flow path between a fluid source and a compressed fluid storage cylinder to prevent the cylinder from being overly filled. The improved valve includes an elongated tubular body having a first seat a first space a second space a second seat a third space a third seat a fourth space and an entrance portion communicating with a source. A passageway continuously communicates the first and fourth spaces. The second and fourth spaces communicate with the interior of the cylinder. A float is contained within the body for movement toward and away from the first seat in response to the liquid level in the cylinder. A valve member is mounted on the body for sealed movement toward and away from the second seat. This valve member separates the first space from the second space. The valve member is biased to move away from the second seat. A piston separating the third space from the fourth space, is mounted for sealed sliding movement therealong toward and away from the third seat. The piston is biased to move toward the third seat. The piston has a variable-area orifice communicating the entrance portion with the third space. The cross-sectional area of this orifice varies as a function of the direction of the flow. When it is desired to fill the cylinder and the float does not engage the first seat, incoming fluid displaces the piston away from the third seat and flows from the entrance portion into the cylinder via the fourth space. However, when the float sealingly engages the first seat, the valve member is caused to sealingly engage the second seat, and the piston is caused to sealingly engage the third seat to prevent further incoming flow from the source to the cylinder.

Title: Cooling control system for an internal combustion engine
Inventor: SANO MITSUHIRO
IPC: F01P11/14
Filed: 1998-08-10
Abstract: A cooling control system by which an internal combustion engine is prevented from overheating, and a fail-safe function exerts its effect. A butterfly valve 34b for regulating the flow of cooling water is rotated by a motor 31, a clutch mechanism 32, and a speed reduction mechanism 33, thereby cooling the engine to be at the most suitable temperature for driving. The aforesaid butterfly valve 34b is given momentum in a direction to open the valve 34 b by a return spring 34e. For example, an angle sensor 34g for detecting the rotational angle of the butterfly valve 34b is included. In a computing unit, when it is determined that an abnormality occurs from the relationship between the data from an encode 34g and the temperature of the cooling water, the clutch mechanism 32 is released, and the butterfly valve 34b is automatically opened. Accordingly the engine is prevented form overheating.

Title: Modular building panel and method for constructing the same
Inventor: THEODORE CHARLES A J
IPC: E04C2/06
Filed: 1998-08-31
Abstract: A modular building panel and a method for constructing the same provides a framework composed of structural members, typically formed of metal, and a backer board typically formed of a cementacious composite for receiving an exterior wall coating surface. The backer board and the framework are separated from, and insulated from, each other by a layer of foam that is applied in liquid form and that expands and cures into a solid form. Substantially no fasteners extend between the backer board and the metal framework to reduce conduction of heat therebetween. The foam serves as an adhesive to hold the backer board rigidly in place at a predetermined spacing from the framework and to anchor the backer board to the structural members. The structural members can comprise U-shaped and C-shaped channel beams for further rigidity and enhanced anchoring. Upon assembly, the backer board and the framework are overlaid upon each other, typically using spacers of a predetermined spacing thickness.  Spacers can be formed from pieces of foam having adhesive or double-sided tape to maintain them in alignment with the framework and backer board. Liquid foam is applied from the interior side of the framework and expands toward the interior side of the framework.

Patent CA-2272627-A1 (CA)
Inventor: ROSENBERG LOUIS B
IPC: G06F3/039
Filed: 1997-11-25
Abstract: An apparatus and a method of implementing a force feedback interface having isotonic and isometric control capability. The apparatus is coupled to a computer that displays a graphical environment. The interface includes a physical object (12) movable in physical space, such as a mouse. A sensor (51, 52) detects the object's movement, and an actuator (48) applies output force on the physical object. A mode selector (250a, 408) selects isotonic and isometric control modes of the interface from an input device or from an interaction between graphical objects.      Isotonic mode provides input to the computer based on a position of the physical object and correspondingly updates a position of a cursor, and applies force sensations to the physical object.      Isometric mode provides input to the computer based on an input force applied by the user to the physical object, where the input force is determined from a sensed deviation of the physical object. The input force opposes an output force applied by the actuator and is used to control a function of an application program, such as scrolling.
