An elongated onset hosel has a front edge and a back edge with the front edge being connected to the front side surface. The back edge has a downwardly extending chamber formed under the top surface of the hosel. A shaft member is mounted on the back of the hosel and extends upwardly at an angle so as to be adaptable to be extended through the armpit of a golfer. Thereby the arrangement operatively creates an overspin on a golf ball and provides for a more accurate and consistent putting stroke. Wherein the back edge includes a backwardly and downwardly extending top section joining with a backwardly and upwardly extending bottom section, the top and bottom sections forming an integrally formed protrusion having an oblong configuration.

Abstract: A process for visualization of a blast wave, which is the shock wave resulting from an explosive charge, is practiced by observing disturbance contours on a liquid-air cloud and interpreting resulting graphical and calculated data to evaluate matters related to the explosive blast wave.

Abstract: An armor piercing projectile having a ramjet engine located at the forward nd such that the exhaust nozzles of the ramjet engine are located at or near the center of gravity of the projectile. A warhead is contained in the center portion of the projectile and is either a shaped charge device or a high explosive warhead. A tail boom with stabilizing fins is located at the rear of the projectile. In an alternate embodiment, the ramjet engine is attached by an extension sleeve to the warhead allowing it to telescope after launch and provide increased standoff for better penetration by the shaped charge. Another embodiment allows the ramjet motor to detach prior to impact at the target to better allow the warhead to penetrate. A further embodiment incorporates an armor piercing subprojectile located within the centerbody of the ramjet motor.

Abstract: A combination gauge measures (1) the depth of the projectile inside a cantube bore after the projectile has been rammed and seated in the lands and grooves of the rifling of the cannontube and (2) any angular deviation of orientation of the rammed/seated projectile normal to the centerline of the cannontube. A data logger electronically records the measured data and a computer stores and analyzes the data.

Abstract: A method for confinement of a gun propellant during the initial stage of ignition provides the ignition by electrical, pyrotechnic, or laser irradiation means. A liquid and or a solid propellant is placed in a substantially closed chamber. A portion of the propellant in a conduit of the chamber exits from the chamber and is cooled in the exit conduit by a thermoelectric or cryogenic means to a sufficiently low temperature for producing a viscous, glassy, or substantially solidified condition to enhance the propellant containment. An ignition stimulus is then applied. A closure means in the exit conduit selectively varies the amount of flow whereby a relatively high temperature and pressure are reached from the chemical energy release of the propellant. Venting of the formed combustive products is provided through the exit conduit whereby sufficient thermal energy is generated to sustain combustion and to ignite the next stage.

Abstract: Apparatus for a gas charged and initiating mechanism launches a projectile f a relatively low mass at a low velocity. The apparatus has a chamber which has an opening at one end. A burst diaphragm is seated within this opening and seals it. The opening also houses the projectile. A check valve is mounted in an aperture at the opposite end of the chamber. The compressed gas is charged through the check valve. The bursting of the diaphragm is accomplished by a pointed rod protruding from the rear of the projectile or by an electrically-powered squib associated with the diaphragm. The bursting of the diaphragm provides a quick-acting means for releasing the compressed gas whereby the projectile is accelerated down the barrel of a weapon. Additionally, a safety device is mounted within the cartridge for preventing the accidental functioning of the launching projectile.

Abstract: Steps of a process for visualization of a detonation wave involve examini measuring, and confirming a fuel-air explosion by using a ground-based fuel bottle oriented horizontally whereby the explosive dissemination creates a fuel-air cloud with its diameter in the vertical plane and a timed delay, proximate charge explodes within the created cloud. A ground-based high speed camera with a line-of-sight, end-on position with respect to the bottle, photographically records the existence of any occurring detonation wave.

Abstract: A double ramped, saboted, kinetic energy assembly automatically aligns a jectile in a gun tube. The assembly has an acceleration activated device consisting of a split centering ring causing alignment during the early phase of the shot motion of the projectile. The assembly also includes a series of small protrusions or a continuous expandable ring which forces and maintains the projectile into a straight aligned position during its traversal of the gun tube. The assembly may have either a smooth bore or a rifled bore gun tube. The disclosure also include a method related to the assembly.

Abstract: A flexible and bowed tow hitch having a A-configuration is adapted for tring a sled behind a snow vehicle. The hitch comprises three plastic straps; two straps form the legs for the A-configuration and the third strap forms the cross-bar for the A-configuration. The ends of the cross-bar strap are physically pressed against the respective ends of the leg straps to form the base terminal of the hitch for attachment to the sled. The other ends of the legs are physically pressed against each other to form the apex for the A-configuration. An elongated bar is embedded between these other ends. The bar is welded to a ring member to form a lunette-type connection for attachment to the snow vehicle.

Abstract: A shaped charge device having a cylindrical housing, an explosive charge with a cavity at one end, a fuze, booster, a multimaterial vertically layered liner having a hemispherical, semi-hemispherical, arcuate or conical shape with a number of segments of materials, each segment in contact with the explosive charge and the cavity, each segment oriented normal, parallel or oblique to the charge axis. The detonating of the explosive charge causes the liner to form a jet of a plurality of the segments. A method of manufacture is also disclosed wherein the liners made in the vertical manner avoid mixing or interaction between dissimilar materials undergoing the jetting action. Vertically layered liners provide excellent material flow and liner collapse diagnostics.

Abstract: A kinetic energy projectile intended to be launched toward a selected tar has a projectile body and a plurality of main fins attached to the projectile body to provide stability thereto in flight. A spoiler fin is attached to the projectile body ahead of each associated main fin for reducing the temperature of the main fins during flight of the projectile, and thereby, the burning of the fins in flight. The spoiler fin is adapted and configured to provide the temperature reduction by changing the aerodynamic flow over the edges and surfaces of the associated main fin, and also may be composed of material having a lower coefficient of heat conduction than that of the main fin. A gap of predetermined width is provided between the trailing edge of the spoiler fin and the leading edge of the associated main fin, this width being selected to create recirculating vortices behind the trailing edge of the spoiler fin sufficient to cool the leading edge of the associated main fin.

Abstract: A finned projectile intended to be launched toward a target has a project body and a plurality of main fins attached to the projectile body to provide stability thereto in flight. In the preferred embodiment, each main fin includes a supplementary fin movably secured thereto for increasing the overall surface area to further enhance the stability of the projectile after launch. A pin and channel arrangement is used for slidably retaining the supplemental fin and the main fins together for deployment under forces on the projectile during launch and flight thereof. The channel arrangement further includes a portion which angles suddenly to lock the supplementary fin in the deployed position. The preferred embodiment also includes putty disposed within the channel for preventing deployment of the supplementary fin during normal handling of the projectile. The putty is shattered upon initial impact with the pin during launching of the projectile.

Abstract: A gas flow alternator cyclically connects a microphone to a dynamic flow ssure and then a reference static flow pressure. The microphone converts the pressures to a resultant alternating differential signal providing a first input to a phase-locked amplifier. A second amplifier input is derived from an optical pickup mounted within the housing. A readout connected in the circuit with the amplifier indicates the dynamic flow pressure.

Abstract: An air distribution connector valve mechanism includes a pair of mating cectors, each having a self-closing, one way valve arranged and adapted to interfere with the self-closing, one way valve of the other connector when the two connectors are coupled together, such that the two valves will then open for unrestricted passage of air therethrough. Each connector has a coupling mechanism for releasably coupling the two connectors together to cause the interference between them. Each of the valves includes a valve body, and a compression spring associated and aligned therewith, in a valve housing having an axis of symmetry within the associated connector. Each valve body is retained and slidable axially within the housing against the force exerted by the associated compression spring, the latter normally urging the valve body against an end wall of the housing to block an opening therein.

Abstract: A mechanical pressure gage for measuring the change in fluid pressure resing from an explosive charge and the like. The sealed gage housing includes a plate member having a recess in which a metalic foil diaphragm means is frictionally mounted therein. The plate member has a wedged-shaped opening centrally located on the plate member and extending therethrough. The diaphragm means covers the wedged-shaped opening and is adapted to be mechanically deformed by a change in the fluid pressure within the housing. A cover plate for the housing also has a corresponding wedged-shaped opening and has scale marking located adjacent to the edge for measuring the extent of the rupture of the diaphragm means upon the fluid pressure change. Another plate member forms a back to the housing.

The shield's shape and composite structure permit the rounds to be more closely stored in tank and depot applications, with reduced danger of propagation of detonation and fratricide hazard.

Abstract: Correlation is used to enhance the temporal resolution capability of incident energy detectors for high bandwidth signals. Such enhanced resolution is attained by using a primary response of the detectors, which may be weak but which accurately replicates the temporal waveshape of the incident energy pulse. A secondary response of the detectors, which is delayed from and more powerful than the primary response, but does not track the incident energy pulse as well as the primary, is correlated with the primary response. The secondary response is preferably passed through an inverse matched filter to provide a pulse more faithfully following the incident energy pulse prior to correlation with the primary response. Circuitry is provided for performing the enhancement, and a modulating device is used to permit the detector to respond to long-duration incident energy.

Abstract: To provide for ease of movement, a decoy capable of misleading smart munins having both radar and thermal sensors utilizes a frame having two sections, with one foldable over the other. On this frame are mounted a plurality of thermal panels for generating representative thermal signatures. In a first embodiment, the order not to interfere with the folding of the frame, a number of hollow polyhedrons used for reflecting radar waves are mounted invertedly onto the frame. In a second embodiment, a number of reflectors, each having in turn a plurality of collapsible right triangular elements, are used for reflecting the radar waves. For this embodiment, since the members of the reflectors are collapsible and would not interfere with the folding of one section of the frame on the other, the reflectors are mounted in an upright position.

Abstract: The present invention decoy is able to simulate an armored vehicle by proing for both thermal and radar signatures. The thermal signature is actively generated by a plurality of thermal panels located on a platform which is configured to have the same passive millimeter wavelength characteristics of the armored vehicle. Accordingly, a smart munition, when viewing the decoy by means of thermal and radar sensors, would conceive the decoy as an actual target.
