Abstract: The internal combustion engine allows charging with an air/fuel mixture into the combustion chamber while the combustion chamber is under combustion pressure and outputs power virtually continuously at the same time, i.e., the novel engine has an almost continuous fuel feed and, due to substantially continuous combustion, it also has an almost continuous power output. The fuel and/or air is injected by way of mutually intertwined worm spindles that form a fluidtight displacement system. The blades of the impeller system are almost flat, i.e., their attack angle relative to backpressure is close to perpendicular so that they will turn quite freely in the forward direction, but will not be turned backwards by a pressurized backflow. The impeller rotation that is introduced via the spindle shafts nevertheless leads to a volume displacement towards the chamber to be pressurized or to be subjected to equal pressure.

Abstract: A novel concept for a propeller blade configuration incorporates the model of the natural wave behavior. The leading edge of the propeller blade is parallel to the trailing edge, but offset by a given amplitude. The surfaces between the leading and trailing edges are rounded so as to promote proper fluid sheet formation along the surface and to reduce undesirable vortice formation. Best results are obtained by modeling the surfaces along a sine or tangent function.

Abstract: A caulking gun and cartridge combination is provided with afterflow prevention. The cartridge has a tubular body, a forward dispensing opening at a forward end of the tubular body, and a backwall movably disposed within the tubular body. The caulking gun has a trough for receiving the cartridge, and a piston movable parallel to the trough. A trigger handle is used for pushing the backwall froward within the tubular body and causing a reduction of volume within the chamber in the cartridge. The backwall slides substantially in a contactless manner within the tubular body, preferably by way of a reduced diameter of the backwall relative the inner diameter of the tubular body, so that it is pushed backwardly when the body retracts radially after actuation. Alternatively, the cartridge body may be prevented from expanding or may even be actively squeezed so that afterflow caused by the volume reduction of the relaxing tube body is safely prevented.

Abstract: A novel concept for a wing or airfoil incorporates the model of the natural wave behavior. The leading edge of the airfoil is parallel to the trailing edge, but offset by a given amplitude. The surfaces between the leading and trailing edges are rounded so as to promote proper fluid sheet formation along the surface and to reduce undesirable vortice formation. Best results are obtained by modeling the surfaces along a sine or tangent function.

Abstract: A rotary internal combustion engine has a cylindrical rotor which rotates in a cylindrical rotor chamber of a stator. A cylindrical peripheral surface of the rotor rotates equidistantly from the housing wall of the rotor housing. A plurality of vanes project radially from the peripheral surface of the rotor and they sealing against the inner wall surface of the rotor housing. Several turning or reciprocating valves are equi-angularly distributed about a periphery of the housing chamber. The valves seal against the rotor periphery and they open up for the vanes to pass by.

Abstract: A flexible material such as garment fabric to be protected against theft is clamped into a lockable security tag. A key can be inserted into a key hole formed in the security tag for releasing the lock and to remove the tag from the garment item. The key thereby has a shape which complements a member of the cam mechanism so as to allow the cam to be operated with the key. A given decoupler is matched to a given batch of security tags, and the given decoupler is not matched to another, different batch of security tags. A certain store, therefore, has a matched decoupler for its tags while another store has a different decoupler which is matched to a different batch. The decoupler is preferably a key. The security tag is thereby provided with a number of pins or prongs which break or bend back if an incorrect key is inserted or if someone attempts to pick the lock.

Abstract: An object detecting apparatus includes at least one transmitter and receiver pair having a transmitter for transmitting waves and a receiver for detecting reflected waves caused by objects reflecting the transmitted waves. The receiver outputs reflected wave detected signals in response to detecting reflected waves. A control unit is connected to the at least one transmitter and receiver pair for providing transmit control signals to the transmitter and for receiving and evaluating the reflected wave detected signals from the receiver. The control unit also determines a distance between the receiver and the object. There is also provided at least one speaker connected to the control unit for providing an audible signal.

Abstract: A device which is worn as an undergarment which cannot be removed without destroying the device. The device is worn in order to guarantee that the wearer has been sexually faithful to ones partner. The device comprises a plurality of loop members and a plurality of longitudinal members interconnecting the plurality of loop members. The device also has a testicle retaining ring having a locking member disposed thereon and attached to one of the longitudinal members. The locking member adjusts and maintains a selected circumference of the retaining ring.

Abstract: In combination with a barrier for retaining shopping carts around a parking lot, a vehicle entrance includes a roadway having a surface and a plurality of geometric objects protruding upward from the surface for entrapping a wheel of a shopping cart when the wheel of the shopping cart is pushed over the geometric objects. Another embodiment includes a water trap in the roadway. All of the embodiments of the invention help retain shopping carts within a confined area such as a parking lot.

Abstract: Disclosed is the method of determining the effectiveness of an agent for the relief of elevation of the blood pressure, comprising the steps ofa) administering to a susceptible subject a quantity of a trigger substance reproducibly effective in producing within a period of six hours a perceptible increase in blood pressure lasting for at least twenty-four hours in the absence of treatment,b) administering to said subject having received said quantity of trigger substance a predetermined quantity of the agent whose effectiveness is to be determined,c) measuring the duration of said elevation of blood pressure upon administering said agent, andd) comparing the duration of said elevation with and without the administration of said agent.Also disclosed are effective quantities of certain nutrient substances which can reproducibly relieve elevated blood pressure produced in a susceptible subject by the administration of a trigger substance.

Abstract: Disclosed are compositions containing either aspartame or monosodium glutanate combined with an amino acid.

Abstract: A caulking gun and cartridge combination is provided with afterflow prevention. The cartridge has a tubular body, a forward dispensing opening at a forward end of the tubular body, and a backwall movably disposed within the tubular body. The caulking gun has a trough for receiving the cartridge, and a piston movable parallel to the trough. A trigger handle is used for pushing the backwall forward within the tubular body and causing a reduction of volume within the chamber in the cartridge. The backwall slides substantially in a contact-less manner within the tubular body, preferably by way of a reduced diameter of the backwall relative the inner diameter of the tubular body, so that it is pushed backwardly when the body retracts radially after actuation. Alternatively, the cartridge body may be prevented from expanding or may even be actively squeezed so that afterflow caused by the volume reduction of the relaxing tube body is safely prevented.
