Abstract: A transthoracic, cannula-type cardiac resuscitation instrument for use in conjunction with a rigid catheter-like needle, and adapted for rapid penetration of and placement in the wall of a person's heart. The instrument includes an elongated flexible tube which permits free axial insertion and withdrawal of such a needle for the purpose of the needle acting, among other things, as a rigid penetration and carrying device for carrying the tube into proper position with respect to a heart. The proposed tube, adjacent its distal end (which penetrates a heart wall during use) carries a pair of axially spaced inflatable-deflatable balloons that are positioned on opposite sides of an exposed electrical conductor usable for supplying electrical pacing pulses to a heart. After placement of the tube, and withdrawal of a needle, the tube may be used for injection of medications into the heart.

Abstract: The present invention relates to an indexing tab for use with a sorting device including a plurality of sheet, or plate-like, divider leaves. The tab is secured to the free end of a divider leaf and includes a central body portion having a thickness greater than the thickness of the leaf and thinner elongate end portions which project outwardly from opposite ends of the body portion. The thick body portion maintains a spaced relation between the free ends of the divider leaves for inserting sheet material therebetween, and the thinner end portions provide guideway spaces into which an edge margin of a sheet may be slipped to insert a sheet between the divider leaves. Beveled exterior surfaces on the tab permit ease of insertion and removal of sheets in the device.

The bottom support, side support, and top support may be swung, concurrently, about a common, substantially horizontal axis 90.degree. in the direction of the side support to lay the stack over on its side with the same being supported by the bottom, side and top supports.

Abstract: A suturing device including a pair of arms having a set of adjacent ends movable toward and away from each other for engaging opposite sides of tissue therebetween. One of the arms has a needle-holding channel formed therein which opens at one end in the direction of the other arm. A manually operable needle driving member is mounted for movement on the one arm to drive a needle from the channel, through the tissue, and into the region of the other arm. The other, or second, arm has a needle receiving chamber therein for receiving the pointed end of the needle driven through the tissue. A rotatable needle holding element adjacent the needle receiving chamber is shiftable between a release position permitting entry of the needle into the chamber and a holding position in which it grips and holds the needle in the chamber.

Abstract: A tool set including a plurality of tools each having a pair of integrally connected elongate shanks disposed at an angle relative to each other and an elongate tool-holding body having a channel open along one of its longitudinal sides and at one of its ends for storing the tools therein with one shank of each tool supported on the base of the channel. A pivot member extending laterally of the channel and spaced outwardly from the base of the channel overlies the shanks of the tools in the channel. A tool is slidable longitudinally of the body to shift one tool shank outwardly to expose a working part thereon and the pivot member permits swinging of the other tool shank outwardly to expose a working part thereon. A frictional, shank-engaging clip engages the shanks of the tools in the channel to hold them either in stored or selected working positions relative to the body. The tools decrease in cross-sectional dimensions progressing from one to the other laterally of the channel.

Abstract: A system for measuring a lineal dimension of a light reflective object. Sequentially generated light markers forming a raster are projected toward the object to be measured, with the markers traveling along individual, parallel paths which are uniformly spaced-apart along the dimension being measured. Markers intercepted and reflected back by the object are photoelectrically detected and counted to determine the size of the object along the measured dimension.

Abstract: Apparatus for transporting golf clubs including a golf club holder comprising an elongate body of foamed plastic material with multiple elongate bores defined in said body extending the length thereof and separated laterally from one another by partition portions in the body. The bores open to the top of the body, and a cover is provided which is positionable to provide a covering for the heads of clubs whose shafts are lodged within said bores. Reinforcing means in the holder includes a base supporting the base of the body and elongate braces extending along the outside and longitudinally of said body. Wheeled structure is disclosed including wheels which roll over the ground and a handle for manipulating the structure.

Abstract: A positioning clamp for holding a workpiece properly oriented with respect to a work station adjacent the clamp. The clamp disclosed releasably holds saw chain during an operation such as grinding of a cutter in the chain. The clamp is releasable to permit the saw chain to be advanced in steps along a channel defined between jaw margins in the clamp. These jaw margins include portions which face each other, and that come against opposite sides of the saw chain when clamping it, which are shaped to complement the shape of the rivet ends usually provided in saw chain to hold it together. One jaw member is mounted for pivotal movement toward and away from the other to effect clamping and release positioning through a ball pivot. The jaw members are biased toward each other to exert a clamping pressure, and selectively operable means is provided for swinging the jaw members away from each other to produce release.

Abstract: Apparatus for precipitating dust from a region surrounding an area from which dust emanates. The apparatus includes a fluid supply conduit for carrying water under pressure to the region adjacent the dust, area, a proportioning pump for injecting a preselected quantity of a surfactant into the water, and nozzles on the conduit adjacent the dust emanating region. The mixture of water and surfactant is atomized and sprayed from the nozzles in a curtain of finely dispersed spray, or fog, adjacent the dust region. The substantially continuous curtain of finely dispersed spray surrounding the dust region acts to precipitate dust particles from the air. The mixture of a surfactant with the water allows the water to easily wet the dust particles, whereby smaller quantities of water may be used with improved dust precipitation occurring.

Abstract: Apparatus for manufacturing a brick having a roughened side surface including interconnected, upright, side plates defining a mold cavity having generally the shape of a brick to be formed. A bottom plate is shiftable vertically from a position against the lower edges of the side plates to form a bottom for the mold and a position spaced a distance therebelow. A power-operated pusher mounted above the side plates is shiftable downwardly into the region between the side plates for forcing a brick formed in the mold outwardly through the bottom of the mold when the bottom plate is lowered. One of the side plates has a lip projecting substantially normally outwardly therefrom into the path along which a side of a brick will be moved as it is forced from the mold. This lip scrapes a side of the brick to produce a roughened surface thereon.

Abstract: A combination air conditioning and fire protection system for a building including a heat exchanger through which fluid may pass under pressure, a fluid conditioning unit operable to bring fluid to a desired temperature for passing through the heat exchanger, and fluid supply and return conduits interconnecting the heat exchanger and fluid conditioning unit for circulating fluid therebetween. The supply and return conduits have discharge heads spaced therealong which are openable in case of fire to discharge fluid therefrom to extinguish a fire in the vicinity of the head. The conduits may include risers in the form of hollow, fluid-tight structural columns which also act to provide structural support for the building. Flow control devices and check valves in the system assure that pressure will be maintained in either the supply or return conduits to discharge fluid onto a fire if the other conduit is damaged and loses pressure.

Abstract: An electromedical patient monitoring system having a minimum likelihood of electrical injury to a patient is provided. Signals from a body-contacting sensor are amplified and processed by self-contained, battery powered apparatus for display by an electrical monitor, such as a recorder. In a preferred embodiment, the apparatus includes an input circuit operatively connected to the sensor and including an AC amplifier. The output of the amplifier is inductively coupled to a synchronous detector, part of an output circuit operatively connected to the monitor. Operating power for both the amplifier and detector is derived from a battery-powered audio oscillator to which the input and output circuits are inductively coupled. Thus, the apparatus provides DC isolation of the sensor from both the monitor and from the power source for the apparatus.
