Inventor: MCCARTHY PETER THOMAS
IPC: B63H1/36
Filed: 1997-01-09
Abstract: Methods are disclosed for increasing lift and decreasing drag on hydrofoils and swim fins. The methods include providing a hydrofoil (104) with a highly swept back leading edge portion (108) and orienting the hydrofoil (104) at a significantly reduced angle of attack in which the reduced angle of attack occurs at an angle that is substantially transverse to the hydrofoil's direction of movement through a surrounding fluid medium. Methods are disclosed for providing a hydrofoil with a substantially longitudinal recess or venting system located substantially along the center axis of the hydrofoil. The attacking surfaces of such hydrofoil are provided with an anhedral contour that forms a substantially lengthwise channel with the recess or venting system located along the center axis of this lengthwise channel.  The central recess or venting system also permits the water flowing in an attached manner along the lee surfaces of the hydrofoil to merge with the water flowing from the attacking surfaces through the recess or venting system so that lift is efficiently generated.

Patent CA-2266026-A1 (CA)
Title: Capacitance sensor
Inventor: KATO RYOCHI
IPC: G01R27/26
Filed: 1997-09-08
Abstract: An electrostatic capacity sensor comprises an electrostatic capacity type detection element in which a detection electrode, a ground electrode and a charge plate interposed between the detection electrode and the ground electrode are arranged in a state that they are isolated to each other; a detection circuit for detecting changes in capacitance of the detection electrode caused by an object to be detected; and a power supply for supplying electrical power to the detection circuit. Since the electrostatic capacity sensor is provided with the charge plate between the detection electrode and the charge plate, it is possible to improve the sensitivity of the detection element, so that it is possible to increase the detection distance. In addition, the variations in the capacitance of the detection element due to the changes in the ambient conditions can be reduced. In this way, the ratio of signal to noise (the ratio of S/N) can be increased, thereby enabling to improve the detection precision of the electrostatic capacity sensor.

Patent CA-2273313-A1 (CA)
Inventor: HYNES JOHN EDWARD
IPC: F25C1/04
Filed: 1999-05-27
Abstract: An ice making assembly for use in a refrigerator has an ice forming chamber positioned in the freezer. The chamber has a water reservoir for receiving water, at least one air inlet passage and an outlet opening for permitting cool air flow to pass through the ice forming chamber and over the water reservoir to chill the water into ice pieces. The chamber has an ice displacing device for displacing the ice pieces from the water reservoir and moving the ice pieces out of the ice forming chamber through the outlet opening into an ice storage bin. The bin has a discharge opening for discharging ice pieces from the ice making assembly. The ice making assembly has a downwardly extending baffle positioned across outlet opening of the ice forming chamber. The baffle is slanted from the vertical back towards the outlet opening of the ice making chamber by an angle of about 5.degree. to partially close the outlet opening and to redirect a portion of the air flow normally exiting the outlet opening back into the ice forming chamber and over the water reservoir. The baffle advantageously redirects air flow back over the water to be chilled thereby increasing the heat exchange between the air flow and water without increasing the energy requirements to effect this heat exchange. The improved heat transfer quickens the freezing of the water into ice pieces or cubes.
