Abstract: An engine body supports a cylinder having a piston reciprocally mounted therein. An auxiliary inlet valve is provided for introducing compressed air into the cylinder above the piston. A connecting rod is pivotally connected between the piston and a lever which is pivotally supported by the engine body. The lever rotatably supports a drive roller which is disposed in contact with a cam surface on a member drivingly connected to an output shaft. The lever is formed of strong elastic material and an operating device selectively locks the lever in a first position where the drive roller is out of contact with the cam surface and in a second position where the lever is deformed so as to act as a bar spring to urge the roller into continuous contact with the cam surface as the output shaft and member connected thereto rotate. A plurality of cylinders and associated components are disclosed including a six cylinder engine arranged in three rows of two cylinders each and two columns of three cylinders each.

Abstract: A universal contraceptive and prophylactic device, and method of using the device, having a condom support device of annular configuration and including an inwardly opening groove formed on the periphery thereof, a securing device that secures the support device in place on person's body, the condom includes an elongate tubular sheath formed of thin, flexible fluid impermeable material, the condom has a closed end an open end and is sized to fit loosely about an erect male organ.

Abstract: A security device to be usable with a dead bolt lock to prevent the lock from being opened from the outer side of an associated door. The security device includes a body member having a space for receiving a dead bolt lock handle and a slidable retainer for locking the handle to the body member with a pin. The pin is attached to one end of a flexible connector with the other end being affixed to an attachment plate mounted on the door. The flexible connector and attachment plate prevent the body member and handle from rotating due to unauthorized turning of the dead bolt.

Abstract: The temperature of a small amount of pilot fuel is greatly increased prior to injection into a combustion chamber. In all forms, the injection nozzle has a heating space for heating pilot fuel and which is in communication with both a main fuel orifice and a pilot fuel orifice. The pilot fuel orifice is always open, while the main fuel orifice is periodically closed by a needle valve. In a modified form, the nozzle includes an extension which extends into the combustion chamber and has the heating space therein. The main fuel orifice and pilot fuel orifice are formed in the extension. When the needle valve is in closed position, it closes the main fuel orifice and also prevents communication between the heating space and the associated fuel injection pump.

Abstract: A method for treating water in a cooling system including a cooling tower and heat exchanger are disclosed herein. The method includes the steps of removing water from the main cooling water circuit, serially subjecting the water to magnetic treatment, treatment with ozone, filtering with a centrifugal separator, and then returning to the main cooling water circuit. Underflow from the centrifugal separator is filtered with a bag filter, and the filtered water returned to the magnetic treatment step. The pH of the water may be controlled by regulating the production of dry air supplied to the ozone generator.

Abstract: A cylinder block includes a cylinder with a piston therein and a main crankcase. A combustion space is disposed above the piston and a compression space is disposed below the piston. An exterior passage including a reservoir transfers compressed air from the compression space to the combustion space. A first valve permits one-way flow of ambient air into the compression space, and a second valve permits one-way flow from the compression space into the passage so that the compression process is independent of the combustion process. In one embodiment, the exterior passage includes a first passage for air and a second passage for fuel-air mixture for selective communication with the combustion chamber. In another embodiment, an inner crankcase is disposed within and spaced from the main crankcase and incorporates the first and second valves.

Abstract: A primary low viscosity fuel and a secondary high viscosity fuel are fed to an injection pump including a plunger which reciprocates and rotates within a bore in a pump housing. The upper end of the plunger defines with the upper end of the bore a mixing chamber. The mixing chamber is connected through a check valve with a fuel injector for injecting mixed fuel into the combustion chamber of an engine. The plunger has a helical groove thereon which is in communication with the mixing chamber. Primary fuel is fed directly into the mixing chamber. The secondary fuel is fed into an annular groove which is in communication with the mixing chamber through a passage formed in the plunger. The high viscosity secondary fuel in the annular groove forms a seal between the plunger and the wall of the bore to prevent the low viscosity primary fuel from leaking past the seal.

Abstract: A stream of liquid is formed having a substantially smooth outer boundary surface contacting ambient atmosphere, and light is introduced into the steam closely adjacent the formation of the stream and in the direction of flow of the stream to be guided downstream by total internal reflection of light in the stream. Exit of light from the stream may be controlled by modifying the outer boundary surface of the stream or by introducing matter into the stream. The light is varied automatically in accordance with the temperature of the liquid in the stream to provide a visual perception of the temperature of the liquid.
