  • Patent number: 5578001
    Abstract: An infusion apparatus includes a roller assembly adapted to exert pressure on opposed sides of an IV bag to forcibly remove the fluid contents therefrom in an even and controllable manner. A sensing element mounted to the roller assembly senses the pressure exerted during the infusion operation and generates a signal to a control assembly which automatically adjusts the movement of the roller assembly in response to the pressure sensed. If the pressure sensed exceeds a predetermined level, the control assembly will activate a drive assembly to return the roller assembly to a neutral position.

  • Patent number: 5556004
    Abstract: A spout for a container is provided with depending wings extending down from a bottom edge of the spout. The depending wings terminate in a point for piercing a container. The depending wings permit the spout to pivot ninety degrees from the container to extend from a container at a ninety degree angle therefrom. The spout has side walls with upper edges having arcs of ninety degrees. The spout is inserted into a container with a ram which drives the spout against a ramp to rock the depending wings upward with respect to the bottom edge of the spout. Thereafter, the ram drives the points into the container and the upper edges of the side walls of the spout contact the container and cam the spout back to a horizontal position to insert the ninety degree spout with the depending wings into a container.

  • Patent number: 5556229
    Abstract: A dynamic shoreline erosion control system includes a plurality of large rotatable hollow spheres spaced along a line at a distance from the shoreline. The spheres are held together by a heavy duty strong flexible netting which permits movement of the spheres with the incoming and outgoing waves. Openings in the spheres permit the sea water to pass through. A plurality of smaller air-filled balls are disposed within the spheres to likewise rotate under the influence of water flow and provide buoyancy. A group of spheres within a common netting is tied to a pair of pilings at the ends of the netting to limit the extent of movement. Narrower sections of the netting between spheres provide a link and spacing for adjacent elements. Like groups of spheres in nettings can be disposed in parallel pairs with staggered spacing and an array of spaced groups in various geometric arrangements can extend along a large shore area.

  • Patent number: 5553698
    Abstract: A conveyor apparatus is provided which includes a pair of conveyor belts constructed from a resilient material and arranged to securely grip and release the neck ring of bottles to be conveyed. Each one of the conveyor belts is formed with a groove having coacting opposed sides. The opposed sides part to open the groove to facilitate and expedite receiving the bottle neck ring in the grooves of the conveyor belts. The opposed sides of the groove then coact to close the groove and securely grip the neck ring therebetween to transport the bottle. At the discharge area of the conveyor line, the opposed sides once again flex away from the groove to facilitate and expedite the discharge of the bottle from the groove of the conveyor belts.

  • Patent number: 5554292
    Abstract: A separatory membrane is provided which has sufficient durability and shows a high rate of permeation therethrough, a high separation factor to a variety of organic substances having a wide range of concentration thereof in mutual separation of organic substances and separation of a water/organic substance mixture by pervaporation, vapor permeation or perstraction. The separatory membrane shows that water permeates selectively through the membrane while satisfying such conditions that the product (QL) of the rate Q (kg/m.sup.2.hr) of permeation and the thickness L (.mu.m) of the membrane is at least 0.5 kg..mu.m/m.sup.2.hr, and that the separation factor .alpha..gtoreq.10 and log.alpha..gtoreq.-1.77.times.log(QL)+2.77 when the pervaporation performance of a 5-30 .mu.m-thick dense uniform membrane is evaluated using, as a liquid feed, an 80 wt. % aqueous solution of acetic acid at a temperature of 70.degree. C.

  • Patent number: 5552829
    Abstract: An image signal coding system encodes analog image signals into digital signals in a high-definition digital video tape recorder (D-VTR). A scrambling portion rearranges the image data of a frame formated in the order of vertical subsampling line into a predetermined unit of blocks to distribute the highly variable portions and substantially linear portions in the image data uniformly, while an activity calculation portion calculates a horizontal projection sum and a vertical projection sum of discrete coding transform factors in a unit block and a block activity, respectively to determine a coding area and a quantization step size.

  • Patent number: 5542672
    Abstract: An electronic controller is provided for controlling fishing simulation computer games. The controller includes a rod handle, a reel housing attached to the rod handle, and a rod shaft pivotally mounted within the reel housing and extending therefrom. The reel housing contains a motor to operate a gyroscope which is also positioned within the reel housing. A plurality of switches to transmit information to the computer game are provided on the reel housing. A reel crank handle extends from the reel housing and includes a break for applying resistance to the reel handle. A rod shaft pivoting apparatus that includes magnets and that act on metal plates attached to the rod shaft to pivotally move the rod shaft.

  • Patent number: 5537765
    Abstract: An identification tag for eyeglasses, spectacles and the like is formed from a flexible member having two opposed end portions and a central portion disposed therebetween. Each end portion has a pair of slots and ribs in parallel arrangement with each other. The slots and ribs are perpendicular to a longitudinal axis of the member. A peripheral edge of the tag is narrower at the central portion of the tag. The parallel slots and rib members coact for receiving a stem portion of an eyeglass frame to maintain the tag at a select position on the stem. An end portion of the tag can be folded back over on itself so that the slots at that end portion are brought into registration with each other for receiving the frame stem which is threaded through the aligned slots.

  • Patent number: 5535007
    Abstract: A method and device for enlarging or reducing an original image to obtain a copy image adjusted in magnification includes designating the image input parameters and calculating the control factors in accordance with the desired magnification, scheduling the function information of the magnification needed for the magnification process to be a form of look-up table, and executing the insertion or omission of the pixel or line which correspond to the desired magnification by an interpolation method. The device includes means for executing the magnification conversion in the main-scanning direction with the insertion or removal of the pixel data, and means for inserting or omitting the scanning line with a control for the phase shift of a motor. The pitches of the output pixels in the main and sub-scanning directions can be set arbitrarily and the magnification conversion can be achieved in a unit of 1%.
