Abstract: A marine propulsion system for use as a driving means and a progressive hull resistance characteristic changing means is herein described. The drive can develop a separation of the jet water stream flow field from the vessel hull, as well as separate the supporting ocean water flow field from the hull. The jet system air cavity doors also act as trim planes and hull planing (hydrodynamic) surface structures, and as thrust vector application control valves (in this capacity, they have the capacity to reduce drag . . . and make a vessel go faster, as well as increase it . . . by varying Coanda effect and hull plate fluid friction). The unit can be used in conjunction with an automated controlling device (such as a computerized control linked to servo motors, feedback potentiometers, and linkages) wherein a specific power-up and power-down sequence can be followed in response to sensor information.

Abstract: An engine or motor is attached in a driving relationship to a water moving device, such as a pump, and a thrust outputing portion, such as a nozzle. Heat generated by and rejected by the engine or motor is passed into the pump base for dissipation into the outputtted jet stream. A supply of gas, such as air, and/or exhausted gases from the motive source is ejected around the outputted water stream in a critically defined boundary layer to reduce (1) against-the-hull turbulence induced by the ejected water flow, (2) water jet stream or thrust energy losses (3) vessel afterbody wake losses, (4) propulsion system underwater noise created by the ejected water stream (acoustical isolation), and (5) the contact friction of water born debree against the vessel hull.

Abstract: A marine jet propulsion system for use as an inboard engine for boats is herein described. An engine or motor means is attached in a driving relationship to a pump and thrust output means. Heat generated by and rejected by the engine or motor is passed into the pump base for dissipation into the outputted jet thrust stream. Air and/or exhaust gas from the engine is ejected around the jet output stream to reduce against-the-hull and jet stream or thrust energy losses. Streamlining hull closures for the jet pump intake and output ports are provided to reduce system hull drag when not in use and to limit marine organism growth inside the pump.

Abstract: The input, driven and counter shafts journaled in a gear transfer case are drivingly interconnected by constant mesh gearing and under control of a clutch mounted on each of the split power shafts. Fluid power controls effect selective engagement and disengagement of the clutches to transmit torque at high and low drive ratios for either two wheel or four wheel drive of a vehicle.

Abstract: A motor mount having first and second mounting surfaces with at least three mounting elements fixed therebetween is used to absorb motor vibration and shock impulses which are produced primarily parallel with the plane of the mounting surfaces. Two of the three mounting elements are dampers which flexibly connect the first mounting surface in a parallel relation with the second mounting surface. The third mounting element maintains a preferred range of distance separation between the mounting surfaces to that a damping flexion potential of the dampers is maintained.

Abstract: Intake fuel supplied to a conditioning tank is mixed therein with engine heated fuel returned from a fuel injector to which mixed fuel from the tank is fed. The mixed fuel in the conditioning tank is degassed by atmospheric venting through a hydrostatic liquid column rising to a level above the conditioning tank.

Abstract: A putter uses an angled mirrored upper club surface with a deeply scribed and pigment filled line to act as a sighting device. In one embodiment, a clear plastic block has a bottom surface coated with a highly reflective coating. A pair of lines are scribed on upper and lower surfaces of the block and must be aligned while the target is sighted in the mirrored surface. Other embodiments utilize deep grooves formed in the top of a mirrored or unmirrored club surface.

Abstract: A generally rectangular framework is constructed to hold a plurality of individual advertizing panels. The bottom and two sides of the frame are formed from channel members connected at their corners and designed to snugly but freely receive the plurality of panels. A pair of panel support members which are formed as parallel spaced walls extend between the tops of the side channel members and form the top of the framework. Each wall is connected to the ends of the legs of an angle iron member, the apexes of which are facing and spaced horizontally by approximately the width of the panels. The apexes are spaced vertically by an amount to allow the panels to be slid between them at an angular orientation so that the panels can be lifted in an angled position, pulled between the angle iron members, and rotated to a vertical position to be dropped between the sides of the channel member on the bottom of the framework.

Abstract: This invention is directed mainly to a propelling apparatus and a control for said propelling apparatus for use with a boat. This invention can be used with a small boat for pleasure and also for fishing. The propelling apparatus comprises a pump in the form of a propeller and a motor for driving the impeller. Also, there is a novel heat exchanger arrangement and a novel mounting device for support of the motor in a driving relationship with the propeller. Further, there is a novel heat exchanger and muffler combination for the exhaust gases from the motor.
