  • Patent number: 4933944
    Abstract: The disclosure is directed to two embodiments for passive and one embodiment for active mode locking of lasers. The passive systems comprise a GaAs/GaAlAs diode laser (810 nm) pumped Nd:YAG (1064 nm) laser sharing the same optical cavity. A KTP crystal is used to produce a sum of the frequencies of the diode and Nd:YAG laser (460 nm). The KTP crystal and trichroic mirror (with a reflectivity at 810 nm less than the reflectivity at the other two wavelengths) combine to create an effective end mirror reflectivity which increases in accordance with the intensity of the pump laser wavelength (810 nm) to mode lock the system. The active embodiment uses successive sum and difference frequency generation to modulate the reflectivity of a cavity output coupling mirror in a continuous wave dye laser or external cavity diode laser.

  • Patent number: 4927415
    Abstract: The disclosure is directed to an apparatus for preventing needle pricks and for safely disposing used intravenous needles. The apparatus comprises a longitudinal body, having first and second ends, an entry and closure mechanism on the first end and an aperture on the second end of the longitudinal body, and a pulling structure which passes through the interior and both ends of the longitudinal body. The pulling structure is attachable to an intravenous needle. The other end of the pulling structure may be attached to a syringe or blood-drawing device. A user pulls on the pulling structure to draw the intravenous needle into the longitudinal body after use. The entry and closure mechanism prevents the needle from exiting the longitudinal body after it becomes disposed within the longitudinal body. The longitudinal body, containing the needle within, can then be disposed of.

  • Patent number: 4890588
    Abstract: A means to control piston movement in relationship to crank arm rotation in an internal combustion engine is provided. There is provided a system to permit the crank arm of an engine to rotate a number of degrees past what would be the normal TDC (TOP DEAD CENTER). There is also provided a means to lift the piston to its highest point when the crank arm has reached its predetermined number of degrees past normal TDC. A mechanical linkage has been provided to replace the usual connecting rod. A short link is assembled to the crank arm bearing by means of a journal. The crank arm length is coupled to a longer link through a coupling pin. The longer link is attached to the piston by a standard piston pin.

  • Patent number: 4881846
    Abstract: The disclosure relates to a built-up playing court structure having a stable moisture content controlled surface layer with playing qualities equivalent to conventional clay courts. The playing court structure comprises a built-up court surface layer, a barrier surface which is substantially impervious to moisture, a containment wall, a subsurface bed of aggregate, and means for controlling the moisture content of the court surface. A subsurface moisturizing and drainage system provides a horizontal playing surface, highly resistant to any washing away of surface materials. Controlling surface moisture also provides a consistent playing surface with no loss of surface materials due to wind.

  • Patent number: 4813333
    Abstract: A dually-adjustable device for firearms is provided which is attached to the muzzle of a firearm to stabilize the muzzle and to suppress the flash during firing. The device is dually adjustable to counter both the magnitude and direction of firing forces. The device is further adjustable to individual firing characteristics as well as varying powder loads in ammunition. The device includes a cylindrical-shaped main body with at least one surface opening. One end of the main body attaches to the muzzle; the main body can be rotated about the longitudinal axis of the muzzle. The device further includes a cap with a gas-restricting opening which attaches to the other end of the main body. This gas-restricting opening in the cap causes a portion of firing gases to back up and flow through the surface opening thereby causing force in the direction of the opening which serves to stabilize the muzzle. A preferred cap comprises a frustum-shaped portion which narrows towards the firearm.

  • Patent number: 4809285
    Abstract: Method and device for correlating the spontaneous emission of photons into laser fields. Atoms of a common lasing medium of multiple laser fields are excited into a coherent superposition of upper levels. When photons are emitted into the laser fields, these emissions are coherent or correlated. The method and correlated emission laser of the invention utilize this correlation to quench the spontaneous emission noise inherent in active laser systems.
