Patent number: 6112522Abstract: This invention uses a body force to trap the liquid component of a fluid in local potential minimums in a continuous cavity in an expander. Shaping of the cavity traps the vapor components of the fluid between these "liquid pistons". In the external combustion embodiment, the cavities have a continuously increasing cross section. Therefore, the surface pressure of the fluid generates an unbalanced force on the containing expander. The cavities are shaped such that components of the unbalanced forces combine to generate a torque, which rotates the expanders. In the preferred embodiment, some of this rotational force is fed back by gearing to revolve the expanders around a rotor axis. This revolving generates a centrifugal body force on the fluid in the expander cavities. In the internal combustion embodiment, the expander stages are preceded by decreasing cross section stages which compress the fuel air mixture. The mixture is ignited and expands in the following stages.Type: GrantFiled: November 10, 1998Date of Patent: September 5, 2000Inventor: Harlow Wright

Patent number: 6112555Abstract: Fused biconical tapered couplers formed from the pulling of heated optical fibers have controllable coupling ratios by dynamically adjusting the heat intensity and pull speed during fabrication. Fiber coupler fabrication begins by arranging two optical fibers, heating the optical fibers using a heat source a predetermined distance from the optical fibers, and pulling the optical fibers at an initial pulling velocity as the heated optical fibers soften. The heat source is moved away from the optical fibers and the pulling velocity is selectively reduced in response to a substantial change in the detected coupling ratio. Changes in the coupling ratio are controlled by selectively reducing the pulling speed and the heat intensity to a point where the pulling of the optical fibers may be halted, and the heat removed, without a substantial change in the detected coupling ratio. The coupling ratio may be monitored at different wavelengths for fabrication of wideband couplers and wavelength division multiplexers.Type: GrantFiled: August 21, 1998Date of Patent: September 5, 2000Inventor: Cary Bloom

Patent number: 6112557Abstract: An improvement to a flat bed knitting machine comprises a wheel positioned on the carrier of the flat bed knitting machine. The wheel turns as yarn passes thereover for knitting, thus allowing the wheel to measure the amount of yarn used. A series of magnets positioned on a bar beneath the needle bed send signals to a sensor attached to the carriage of the knitting machine as the sensor passes thereover. These signals instruct a logic circuit contained within a logic circuit control box to accept input from the wheel. The magnets are spaced apart by the distance of a known number of needles. Thus, the amount of yarn used can be divided by a known number of needles to arrive at a stitch size to help in the calibration of the flat bed knitting machine.Type: GrantFiled: November 27, 1998Date of Patent: September 5, 2000Assignee: Carla A.
