Title: Water saving device for a flush toilet
Inventor: PIGEON E RICHARD
IPC: E03D1/14
Filed: 1993-04-16
Abstract: ABSTRACT         A water saving device for a flush toilet having a water tank and a buoyant type flapper valve that in a closed position covers an outlet opening in the bottom of the water tank.  The device comprises a modified lift arm directly connected at one end to a flushing handle to be pivoted thereby, with a second portion of the arm being positioned generally above the flapper valve.  In place of the usual chain, a rod is provided, connected at its lower end to the flapper valve and at its upper end to the free end of the arm.  Movement of the handle in one direction, initiating a flush cycle, will pivot the lift arm and, through the rod, raise the flapper valve to an open position to permit discharge of water from the tank.  Movement of the handle in the opposite direction will pivot the lift arm causing downward movement of the rod forcing the flapper valve into the closed position; this can be done before the normal flush cycle is complete, thus saving water.  The water saving device offers full control over the volume of water spent in a flush cycle.

Patent CA-2098268-A1 (CA)
Inventor: NAKA YASUHIRO
IPC: C03C25/12
Filed: 1993-06-11
Abstract: ABSTRACT     In a heating furnace an optical fiber preform is heated and the optical fiber is drawn.  The obtained optical fiber is cooled by a cooling gas in a cooling apparatus provided beneath the heating furnace, then a resin is coated on the outer circumference of this optical fiber by a resin coater. At this time, the blowing direction of the cooling gas blown out from the optical fiber inlet of the cooling apparatus is inclined exactly by a predetermined angle (.theta.) with respect to the axial line of the running optical fiber.  As a result, even if no rise suppression gas is used, it is possible to prevent the cooling gas blown upward from the cooling apparatus from entering into the heating furnace and thereby to prevent the lowering of the quality of the optical fiber due to the adhesion of dust.  Also, a cooling apparatus container enclosing the cooling apparatus is provided.          The cooling of the optical fiber is carried out by the cooling gas while holding the inside of this cooling apparatus container at a positive pressure with respect to the outside environment by a positive pressure forming gas from which dust has been removed. As a result, the rise of the manufacturing cost of the optical fiber production apparatus can be prevented.

Title: Improved prosthetic heart valve
Inventor: STUPKA JONATHAN C
IPC: A61F2/24
Filed: 1992-03-03
Abstract: Heart valves (301), particularly those having two identical leaflets (305), are shown which utilize improved pivot arrangements that create prompt response to flow reversal and minimize impact at the instant of closing. Illustrated are valves having pairs of leaflets (305) that can assume an orientation in the fully open position that is precisely parallel to the centerline of the passageway, yet which will promptly respond upon blood flow reversal and quickly close to prevent substantial regurgitation. The ability of the leaflets to assume a precisely parallel or low energy position in the bloodstream reduces pressure drop across the valve and results in improved flow characteristics. Prompt closing pivoting movement from a parallel orientation is effected by creating a camming action adjacent the upstream edges (371) of the leaflets or close thereto while positively guiding the overall path of leaflet translation and rotation by interengagement at other locations (359, 327) spaced downstream therefrom. The pivot arrangements are particularly effective to positively guide the leaflets to assure effective closing movement regardless of momentary deviations in the dynamics of the reverse flow of blood through the valve.

Abstract: The present invention is to describe an embodiment of the differential coupling and compounding power system of electric transmission storing type which uses the output shaft of an engine (or other gyroscopic power source) to connect with a magnetic coupling driving device, which is a brush or brushless alternate or direct current dynamo through differential gear and engine output shaft coupling, or which is a dual end shaft of which either end is respectively connected to a turnable magnetic field and a turnable rotor, or which is formed by a turning shaft (or a shaft of magnetic field) of gyroscopic rotors used as a main output shaft: this kind of device which can produce the engine output and magnetic coupling driving device itself can produce the output and their output power and speed can be added to each other, and their adding process will not be affected by their speed relation between them. So the volume of this system can be smaller, it becomes compact, its cost is reduced. It can be controlled by the control device and it can have the driving function of a motor when current is input in it. It is also used to generate power and output power the produce the transmission coupling function through coupling torsional moment of output current, or to start an engine and to brake the reproducing power, especially to charge the battery through the turning speed difference between gyroscopic magnetic field and rotor when the engine is individually driving. To control the charging current, it can get the turning speed difference between current adjustment and loading. The engine can be in a constant speed or partially modulated speed so as to keep a higher speed and lower pollution work speed and its magnetic coupling driving device produces differential speed output; that is, it can be provided with a charging power for a battery and a transmission coupling to improve the engine's efficiency and reduce the pollution. Rather, it can also be used as a driving motor soly for a gyroscopic output driving load or used together with the engine for a gyroscopic driving load.
