  • Patent number: 5397180
    Abstract: A motionless mixer tube for mounting on the end of a discharge nozzle of a dispensing device for mixing and dispensing extremely small volumes of a pair of liquid materials, such as chemical reacting resins. The mixer tube has an elongated housing with a female luer lock at one end for mounting the tube on the dispensing device, and a male luer lock on the other end for easily mounting a dispensing needle on the outlet end of the housing. A helical motionless mixer element is mounted in a bore of the tube housing and extends from immediately adjacent the outlet end of an inlet socket of the female luer lock to immediately adjacent the outlet end of a discharge nozzle of the male luer lock. The dispensing needle is mounted immediately adjacent the outlet end of the discharge nozzle and mixer element. This arrangement avoids dead spaces within the mixer tube to prevent the formation of disruptive air bubbles therein and enables secure and rapid attachments at both ends of the tube.

  • Patent number: 5388550
    Abstract: An apron adapted to be fitted to an existing sanitary facility for animals having a pan containing litter and a cover. The apron includes a shallow tray which is divided into first and second compartments wherein the first compartment has a top wall formed with an opening for receivably mounting the pan therein. A plurality of serrations are formed in the top wall to provide a number of breakaway portions to form various size pan receiving openings. The second compartment extends in front of an access opening formed in the pan cover and a screen is mounted over an open top of the compartment. As the animal exits the pan through the cover opening it passes over the screen, whereby debris trapped in the animals paws will be dislodged and will and pass through the screen and into the second compartment. A vanity panel extends in front of the access opening, on the opposite side of the screen from the cover opening to prevent the animal from jumping over the screen without first walking over the screen.

  • Patent number: 5383557
    Abstract: A container for storing a tape cassette of the type having a pair of spaced tape reel hubs. Each hub has a cylindrical sidewall which defines a recess in the hub. The storage container includes enclosure means for receiving and enclosing a cassette in the container. Diametrically opposed pairs of fingers are molded integrally with a bottom wall of the container and project into the hub recess through an aligned access opening formed in a bottom wall of the tape cassette upon placing the cassette into the container. The fingers are formed with a convex outer camming surface and are connected to the container by a straight leg portion. The convex outer edges of the fingers are engaged by the hub sidewalls and flex inwardly upon initial placement of the cassette into the storage container. A rigid stop member is mounted adjacent to and inwardly of each of the flexible fingers to limit the inward movement of the fingers toward the flexed position to control the flex thereof and to prevent breakage of the fingers.

  • Patent number: 5372569
    Abstract: A method and apparatus for accurately positioning a plurality of slotted boxes which are in a flat collapsed state, in a magazine of a box erector. The box erector handles and sets up the boxes into a position having an open top for subsequently receiving items therein while moving bottom closure flaps into a generally closed position. A laser unit is mounted adjacent a box supply loading magazine of the box erector and projects a beam of light against a box placed in the magazine. The magazine then is adjusted until the fixed light beam strikes a predetermined location on the box, preferably the end of a slot formed between adjacent major and minor flaps of the box. This light beam strike location correlates with a location at an unfold station of the erector which receives a bottom corner of the box.

  • Patent number: 5371348
    Abstract: A portable device (10) for data collection by an operator (11) includes a data entry unit (12) for entry of data other than by scanning and a module (14) having a display (50) for display of information and a scanner (51) or other auto-identification device for data collection. Data entry unit (12) operates both when carried by hand and while carried on operator (11) other than by hand. Module (14) is detachably carried by data entry unit (12) and operates both while module (14) is carried by data entry unit (12) and while detached therefrom. Data entry unit (12) includes a module carrier (70) for adjustably, detachably carrying display/scanner module (14). Because module (14) includes both a display and scanner, both are always within the line of sight of operator (11), greatly facilitating use of device (10). Because data entry unit (12) includes the remaining components, module (14) is lightweight and may be used for long periods without fatigue.

  • Patent number: 5363045
    Abstract: A portable hand held diagnostic tool which non-invasively detects an electric field when placed adjacent a component of a spark plug firing portion of an ignition system and provides a positive indication of the detected electric field. A printed circuit board containing a control circuit, a replaceable battery supply, an ON/OFF switch, an indicator such as an LED, and a pickup antenna, is slidably mounted within the hollow interior of a dielectric tubular case. The antenna is located adjacent a pickup end of the case and detects the electric field generated by an ignition system during firing of a spark plug which actuates the LED in response to the detected firing. The dielectric case is free of external metal parts adjacent the pickup end to help minimize arcing. A battery test circuit may be incorporated into the control circuitry to ensure an adequate power supply for operation of the control circuitry. A fixed or variable resistor enables the sensitivity of the firing pickup to be selected.

  • Patent number: 5358140
    Abstract: An adhesive bandage dispensing system includes an elongated strand of individually sterile-wrapped adhesive bandages and a reusable dispenser for storing and dispensing the bandages. Each bandage is contained in a separate sterile compartment of an otherwise continuous wrapping material. Perforations formed in the wrapping material around each compartment allow the compartments to be individually opened. The strand is loaded into the dispenser, which is secured to a stable surface, so that the leading edge of the strand is frictionally held in biased guide flanges and protrudes from a dispensing opening defined by the flanges. The leading edge of the strand is pulled from the dispensing opening until an entire bandage is exposed, then the strand is pulled sharply to completely break the perforation, and the bandage can then be removed from the excess wrapping and prepared to be applied to a wound using both hands, if necessary.
