Patent number: 6796407Abstract: A hydraulic brake system includes a hydraulic accumulator that stores much of the energy generated upon brake pedal depression. The stored energy can be used to maintain the brakes in their fully engaged state and to help return an applied brake pedal to its released position, in which case return fluid flow to the master cylinder is damped to avoid undesirable severe kickback of the brake pedal. A booster is provided to automatically boost the energy storage capacity of the accumulator during normal brake and hold cycles in order to provide sufficient energy accumulation to compensate for relatively severe pressure drops occurring, e.g., during prolonged periods of storage at extremely low temperatures. The booster may comprise an indexing arm that is acted upon by the system's brake pedal to selectively move a variable thickness spacer on the indexing arm into and out of engagement with the accumulator.Type: GrantFiled: December 3, 2002Date of Patent: September 28, 2004Assignees: Hayes Brake LLC, Textron, Inc.Inventors: James A.

Publication number: 20030205351Abstract: Precision castings requiring a fine finish and having complex internal geometries can be produced by casting a semi-solid thixotropic metal alloy within or about a melt-away metal component in the form of a core and/or a die insert that has a lower melting point than the solid-to-semi-solid transition temperature of the thixotropic alloy The thixotropic alloy may be cast, e.g., by thixocasting, rheocasting, sub liquidus casting. Then, after the alloy solidifies to form a casting with a captured melt-away component, the component is melted from the casting, preferably using a liquid bath. Process robustness, speed, and versatility can be enhanced by coating the component with a thin, uniform, abrasion-resistant, and thermally resistant coating that prevents excessive heat from being transferred to the component from the alloy and that prevents the component from alloying with the casting.Type: ApplicationFiled: May 15, 2003Publication date: November 6, 2003Applicant: Chipless Metals, LLCInventor: James A.

Patent number: 6597689Abstract: The Intelligent Multiservice Access System (IMAS) enables support for the next generation of virtual connections. Regardless of whether the communications lines coupled to the inputs and outputs of the IMAS are based on SVC, PVC, or a combination of PVC and SVC, the IMAS can support SVCs for a more flexible, timely, efficient, and manageable connection. In the more typical configuration, the loop side of the IMAS is PVC-based because the modems do not support SVC signaling, and the telecommunications backbone side is capable of supporting SVC signaling even though existing DSLAMs do not employ SVC signaling logic. With SVC support, the IMAS assists the ATM network in hand crafting an SVC-based connection almost immediately between end users when the originating end user wants to make a call to a destination end user, and tear down that virtual connection almost immediately when that call has completed.Type: GrantFiled: December 30, 1998Date of Patent: July 22, 2003Assignee: Nortel Networks LimitedInventors: Manfred F.

Patent number: 6564856Abstract: Precision castings, such as brake calipers and other parts requiring a fine finish and having complex internal geometries, can be produced by casting a shot of a semi-solid thixotropic metal alloy about a core, preferably a hot-chamber die-cast core, having a lower melting point than the solid-to-semi-solid transition temperature of the thixotropic alloy. Then, after the shot solidifies to form a casting with a captured core, the core is melted from the casting in a liquid bath, in an air furnace, or during other heat treatment of the part. The process dramatically reduces or even eliminates machining requirements for cast metal parts because the inner surface of the casting is of extremely low porosity and meets stringent tolerance requirements and because the melt-away core can be formed with protrusions that prevent mechanical removal of the core from the casting and that form undercuts, threads, bores, etc. in the casting.Type: GrantFiled: April 17, 2000Date of Patent: May 20, 2003Assignee: Chipless Metals LLCInventor: James A.

Patent number: 6546889Abstract: A steering transmission transmits steering forces that must be transmitted from a steering mechanism, such as a steering wheel or handlebars, to a steered mechanism, such as the rudder of a boat or the steered wheel(s) of an off-road vehicle. The steering transmission includes one and preferably both of a multi-ratio speed changer and a torque gate. The multi-ratio speed changer preferably takes the form of one or more planetary gear sets coupling an input shaft of the transmission to a rotary output of the transmission. The speed changer is shifted by manually operating a shifter to switch between two or more distinct speed change ratios, thereby permitting the operator to select the combination of responsiveness and steering effort desired for the prevailing operating conditions. The torque gate preferably takes the form of a release driver, a locking driver, and a wrapped spring disposed between the release driver and the locking driver.Type: GrantFiled: August 30, 2001Date of Patent: April 15, 2003Assignee: Hayes Brake, L.L.C.Inventors: William V.
