  • Patent number: 5445618
    Abstract: A rectangular hypodermic syringe with a needle that can not be re-used once a nonlinear needle has been moved to a needle protecting retracted position includes a rectangular cylinder; a rectangular plunger for displacing the fluid within the cylinder; a rectangular needle guard, having an interior chamber, demountably attached to the rectangular cylinder; an elongate needle assembly, having a nonlinear needle, slidably mounted within the interior chamber of said needle guard; and means for fluidly coupling said cylinder to said needle when the needle assembly is in the extended position and for fluidly separating the cylinder from the needle when the needle assembly is in the retracted position. Lock means locks the needle assembly in the needle exposing extended position. Release means unlocks the needle assembly allowing a coil spring to move the needle assembly to the needle protecting retracted position.

  • Patent number: 5446440
    Abstract: A centrally powered, low voltage emergency sign and control circuit using high voltage AC power simultaneously providing continuous low voltage DC power to a plurality of emergency signs connected in parallel through a plurality of branch circuits and to continuously charge a single battery backup to all of the emergency signs should AC power fail. Each emergency sign is illuminated by electroluminescent diodes which are individually connected in parallel and in series throughout the emergency sign. When a fire alarm or emergency situation exists, the control circuit pulses the low voltage DC power to the emergency signs causing the LEDs to flash regardless if the control circuit is powered by high voltage AC power or backup battery power.

  • Patent number: 5439066
    Abstract: A method and system for translating the orientation of a length of coil tubing from a generally vertical orientation to a generally horizontal orientation, inside a well borehole and downhole of a wellhead. A first conduit is installed and suspended in a well borehole. The conduit is provided with a coil tubing bender at the downhole end of the conduit. Coil tubing is injected into the conduit through an upper packer attached to the top section of the conduit. After a section of coil tubing is injected into the conduit, an outer coil tubing seal is securely affixed to the coil tubing. The coil tubing is run to the top of the bender; the packer is closed; and high pressure fluid is introduced between the upper packer and the outer seal inside the conduit. The fluid forces the coil tubing through the bender and translates the coil tubing from a vertical to horizontal orientation.

  • Patent number: 5439135
    Abstract: A golf tee dispensing device capable of individually releasing one of a number of standard sized golf tees from a plurality of tees stored and retained within the dispensing device. The device includes a tube for the ordered retention of the golf tees and a means for forcing the golf tees upward to an open end of the tube for release. The dispensing device incorporates a pivoting mechanism on the open end of the dispensing tube that is structured so as to singularly release a golf tee from the dispensing device and simultaneously preventing the release of a subsequent golf tee next in line within the tube. A spring within the tube forces the golf tees up through the dispensing tube and appropriately positioned stop tabs on the dispensing mechanism prevent and control the release of the golf tees one at a time from the device.

  • Patent number: 5431300
    Abstract: The application discloses a device (10) to retrofit into the cabinet (11) of newspaper vending machine racks to prevent the removal of more than one copy of the newspaper for each vend or door opening of the cabinet (11). The single vend device (10) consists of a front panel (12) with a T-slot (14). The arms (14a) of the T-slot (14) are normally closed off with a pivoted closure plate (16). Consumer access to the newspapers is provided through the leg of the T-slot (14b), but the newspaper must be slid through the gap between the closure plate (16) and the front panel (12). The thickness of the gap is adjustable to selectively allow for the variation in thickness between various editions of the newspaper. The closure plate (16) is spring loaded to be biased to the closed position. Following removal of the paper, the closure of the plate (16) and a locking pin (32) prevents the plate (16) from re-opening. The locking pin ( 32) is disarmed upon closure of the cabinet (11) door (25a).

  • Patent number: 5431149
    Abstract: A solar energy collector comprising a plurality of heat absorbing modules formed by deforming two plates into intimate contact with parallel metallic pipes disposed intermediate the plates. The plates are secured together by rivets which are spaced along and traverse the deformed portions of the plates, thus providing a spring section to absorb unequal expansion of the plates and the fluid conducting pipes. The uppermost surface of the pair of plates is provided with a black body coating to emit infrared radiation when sunlight is incident thereon. A glazing is provided over such black body surface to freely transmit incident light to the black body surface but to reflect infrared heat energy emitted by the black body surface. Water or other heat transfer liquid flowing through the pipes is maintained at a sufficiently high pressure to produce a turbulent flow through the pipes to increase the efficiency of the heat transfer.

  • Patent number: 5411484
    Abstract: A biomedical tube stabilizing device comprised of a soft cincture made of a resilient, sterilizable material having a permanently formed loop for receiving a biomedical tube such as a tracheal or esophageal tube at one end. Following intubation, the loop is placed over the exposed portion of the biomedical tube, and the free end encircles the head and is wrapped around the biomedical tube. The tube is secured by pulling the free end in opposition to the loop engaging the biomedical tube and attaching it to the body of the encircling cincture with a tab of Velcro-like material. An alternative embodiment calls for the biomedical tube receiving loop to be formed by releasably attaching one end of the cincture to itself with a tab of Velcro-like material. An additional embodiment applies a treatment to the inner surface of the biomedical tube receiving loop in order to increase grip strength.
