Abstract: A combustion engine, which is highly efficient, noiseless and lightweight, includes a combustion chamber without pistons. The combusted and expanded air exiting the combustion chamber flows into a displacement pump, such as a gear pump or radial vane pump. The displacement pump drives the load, and, in addition, another smaller displacement pump, which pressurizes fresh air and introduces same, via a feedback loop, into the combustion chamber. Gas or other burnable fuels are introduced in the combustion chamber, so that a continuous fuel burning will occur, after being ignited. The ratio of bigger to the smaller pump is influenced by the percentage of expansion of the air in the combustion chamber.

Abstract: A system and method of preventing unauthorized use of a credit/debit card whereby a new PIN code is used for each new transaction. The user/card holder is in charge of generating each new PIN code. When entering the PIN code, a new PIN code is entered at the same time which replaces the last PIN code. Since only the user/card holder knows this ever changing new PIN code, this system is virtually fraud proof. In an enhanced version intercepting the new PIN code or watching what digits are used by the card holder would be worthless since a secret number only known by the card holder would have to be added to the last PIN code when used for the next transaction.

Abstract: A system and method for identification purposes or for preventing unauthorized use of a credit/debit card and its numbers. For each new transaction, a new PIN code is needed. After usage, the code is deleted and the card and its numbers cannot render a transaction until a new code has been established. The PIN code can consist of numbers, letters or a word. The user/card holder can be in charge of generating each new code. When entering the code, a new code can be entered at the same time which replaces the last code. The new code could also be entered at a later time by using a phone or the internet. During communication between parties over, such as a telephone or over the internet, only a portion of the card number would be included in the communication, along with a predetermined password.

Abstract: The invention is a method of showing images at different depths and a display that shows images at different depths. The method includes disposing one or more display screens, which are at least partly transparent, in front of a further display screen so that a viewer sees images displayed at different depths on the different display screens.

Abstract: An infinitely variable speed gear transmission transmits a torque from an input shaft to an output shaft. A conical member is mounted to the input shaft and it is formed with a helical gear. A rider wheel formed with worm gear toothing meshes with the helical gear on the conical member. The rider wheel is mounted for rotation about an axis substantially orthogonal to said input rotational axis of the input shaft and for translation along said peripheral surface of the conical member. The output shaft is directly or indirectly coupled with a form lock to the rider wheel.

Abstract: A projectile that is primarily suited for supersonic flight, such as a bullet, a shell, or a rocket, incorporates the model of the natural wave behavior. The leading edge of the projectile has a sharp tip which merges smoothly into a cylindrical body. The merging segment from the tip to the cylinder may be defined with a tangent function. The rounding of the surfaces promote proper fluid sheet formation along the surface and to reduce undesirable vortice formation and thus to reduce the value of several drag factors.

Abstract: A method and treatment for removing an unwanted living organism from a person includes administering topically to the person an effective amount of a solution including a pyrethrin compound and piperonyl butoxide. The term “pyrethrin compound” includes pyrethrin, cinerin, and allethrin. A carrier formulation can be added to said piperonyl butoxide and said pyrethrin compound to form a cream, an emulsion, a lotion, an ointment, or a paste. The carrier formulation can be based on petrolatum, mineral oil, vegetable oil, denatured ethanol, or isopropyl alcohol. The method and treatment can be applied for treating cuts and bruises, reducing body odor, repelling insects, and diminishing parasites.

Abstract: A novel concept for a hydrodynamically and aerodynamically improved leading edge and trailing edge structure is primarily suited for high-speed motion, such as near Mach 1 and above, but also for slow-speed motion and for stationary operation, where stationary structures are subjected to fluid flow. The configuration incorporates the model of the natural wave behavior. The leading edge of the aircraft, of the train, of the submarine, or the like, has a sharp tip which merges smoothly into a cylindrical or rectangular body. The merging segment from the tip to the cylinder may be defined with a tangent function. The rounding of the surfaces promote proper fluid sheet formation along the surface and to reduce undesirable vortice formation and thus to reduce the value of several drag factors.

Abstract: A blade or wing configuration has a leading edge and a trailing edge, and an upper surface and a lower surface extending from the leading edge to the trailing edge. At least one of the upper surface and the lower surface is formed with a curved segment and a straight segment. The curved segment starts from a starting point on the upper surface or the lower surface between the leading edge and the trailing edge and ends at the leading edge. The straight segment extends from the starting point to the trailing edge. A tangent at the leading edge is substantially parallel to the direction of movement and the straight segment forms an angle ? of approximately 30°-60° with respect to the direction of movement. The trailing edge can be formed with teeth.

Abstract: The engine has an input system formed with a fluid displacement pump that enables substantially continuous pumping from a low-pressure side to a high-pressure side substantially without any backflow or backpressure pulsations. The output system has a first output device which provides for the mechanical work output of the engine and a second output device which feeds back to drive the input system. Any increase in the load to be driven by the first output device translates into a proportional increase in the drive energy fed back to the input system.

Abstract: A novel concept for a propeller blade configuration incorporates the model of the natural wave behavior. The leading edge of the propeller blade has a convex segment followed by a concave segment, as seen in a plan view. The leading and trailing edges are rounded so as to promote proper fluid sheet formation along the flat surfaces and to reduce undesirable vortice formation. Best results are obtained by modeling the surfaces along a sine or tangent function.
