Title: Submerged water wheel for energy conversion - radical paddles offer max. flow resistance when moving upstream and minimum when moving downstream
IPC: F03D3/06
Filed: 1983-09-16
Abstract: The wheel has eight radial paddles (3) mounted on an axle (2). The ends of the axle are supported by bearings in a fixed frame (1). The wheel is coupled to an electric generator or other energy convertor. In each paddle are three blades (8) each made from three flat (11) hinged together. One end of each blade pivots in the paddle and the other end is free. - When a paddle is above the axle, moving with the current water pressure holds the blades against stopping bars in line with the paddle, thus presenting resistance to the water flow and providing torque. When the paddle nears a horizontal position the current ''bends'' the blades, thanks to the plate hinging, and lifts the free ends of the blades out of the paddle so that the blades swing out at an angle to the paddle, providing minimal resistance as the paddle moves under the axle against the current.

Abstract: BURNER IGNITION SYSTEM                       ABSTRACT OF THE DISCLOSURE            A burner ignition circuit produces high frequency sparks between a pair of spaced electrodes connected to opposite sides of a secondary winding of a transformer in response to the repetitive discharge of a capacitor through the primary winding under the control of an SCR powered by a full wave rectifier such that sparks are produced throughout both half waves of AC power.  The discharge capacitor is primarily charged from the power supply through a current limiting resistor.  The turn-on time of the SCR is minimized by a trigger circuit including a diac which discharges another capacitor into the gate of the SCR when the voltage there-across exceeds a selected value.  Circuitry including a diode connected be-tween the capacitor and the primary winding is provided to prevent LC oscillation between the discharge capacitor and the primary winding of undesirable residual energy stored in the inductance of the primary winding immediately following each turn-off of the SCR.  In one embodiment, the diode is connected to the capacitor through the current limiting resistor and this undesirable oscillating energy is used to provide a further source of charging current for the discharge capacitor.  In another embodiment, a diode and resistor are connected in a closed loop with the primary winding, and the residual energy is dissipated by the resistor.

Abstract: Abstract of the Disclosure The present invention relates to couplings and, more parti-cularly, to spindle couplings of the type used in connecting a powered prime mover to the rolls of a rolling mill or connecting the pinion stand to the rolls, as well as to like apparatus.  The usual type of spindle coupling presently employed in rolling mill practice includes a coupling sleeve at each end of a spindle shaft.  The coupling sleeve at one end connects drivingly to a prime mover or pinion stand and at the other end to the spade end of a roll in the rolling mill.  When it is necessary to change a roll in a mill, the roll is withdrawn from the roll-end coupling sleeve and a new roll is inserted into the coupling sleeve.  When the roll is withdrawn, the coupling sleeve, acting under the influence of gravity, tends to sag and thereby become misaligned axially with the spindle.  The coupling sleeve is so misaligned that it is difficult to insert the roll spade end thereinto unless the coupling sleeve is raised by applying an external force to it, which is costly and time consuming.  In the present invention, a roll-end spindle coupling comprises a thrust ring having a spherical surface that coats with a flex hub and is maintained in such coacting relation by an end ring secured to the roll-end coupling sleeve.  In this way an aligning thrust force acts continually between the hub and a thrust ring, and axial movement of the roll relative to the spindle does not result in axial movement of the coupling sleeve.  Also, no thrust is imposed on connected thrust bearings and no bearing failures can result from axial thrust forces.
