  • Patent number: 5316169
    Abstract: An especially configured, ringless, container-lid design is disclosed having improved sealing characteristics applicable to paint containers for the consuming public. The rim portion of the container is provided with a tapered, especially shaped wall section terminating in a curled bead which is received in a sealing groove in the lid. The container rim section is rigidized by a single protrusion in the form of a stiffening groove to prevent vertical collapse of the container. The lid has an inverted U-shaped groove sealingly engaging the container's bead. Extending from the inner wall segment of the U-shaped groove in the lid is a frusto conical wall segment extending radially-inwardly and vertically-upwardly to a flat, annular, radially-inwardly extending surface which in turn terminates in a downwardly-extruding frusto conical surface so that a raised collecting basin is formed in the lid.

  • Patent number: 5296300
    Abstract: A method of treating a terne coating to accelerate the patina on the terne coating. The terne coated metal is coated with a specially formulated asphalt based paint which produces a semi-transparent or translucent, dull finish on the terne coated metal. The coated terne coated metal is then exposed to the natural atmospheric elements for at least six months wherein such time enhanced oxidation of lead and tin occurs.

  • Patent number: 5287006
    Abstract: An anti-theft device that is adapted to be connected adjacent to or on a battery of a motor vehicle and including a power switch for disconnecting the battery from its standard battery cable when current flowing through the cable exceeds a preselected substantial amount of current associated with an attempt to start the vehicle. A lockout circuit is actuated by a remote transmitter for generating an external command signal to override the operation of the power switch. This device can be attached directly to a battery without external wiring and still provide the passive or self-arming anti-theft device.

  • Patent number: 5284419
    Abstract: Propeller with twistable blades comprising a spar with ribs which can be rotated in opposite directions about the axis of the spar by an adjusting device. A coupling device in the propeller ensures that when two ribs are rotated in opposite directions by the adjusting device, the other ribs are adjusted accordingly. The coupling device consists of a rod substantially parallel to the spar and designed to be relatively bendable in the plane through the spar and the rod, and relatively resistant to bending in the plane perpendicular thereto. The rod couples at least three ribs together in such a way that it distorts when two ribs are rotated in opposite directions along a helix about the spar, causing subsequent ribs to move with it on this helix.

  • Patent number: 5284040
    Abstract: Tube bending apparatus comprising a lower support carrying a mandrel having a bending groove providing a bend axis, and an upper support mounted on the lower support for rotation about the bend axis and carrying a forming member for urging a tube between the mandrel and forming member into the bending groove on rotation of the upper support relative to the lower support. The upper support is adapted to be rotated relative to the lower support through a drive shaft arrangement extending downwardly from the lower support and coupled with a drive unit having an output coupling coaxial with the drive shaft and transverse to the axis of the drive motor of the drive unit. A stand supports the bending apparatus and drive unit relative to an underlying support surface during operation of the bending apparatus.

  • Patent number: 5279591
    Abstract: A protector guard housing is disclosed for a catheter type needle apparatus to prevent accidental needle puncture. The guard housing is initially positioned between the hub of the catheter and the handle of the needle which slidably extends through the catheter in a known manner. A detent mechanism initially retains the forward end of the guard to the catheter hub while needle supports within the guard permits the needle to axially move relative to the guard. When the needle is withdrawn from the catheter after site puncture, a resilient closure wall formed in the protector closes the protector's forward end while the needle's cutting end is simultaneously wedged into contact with friction retention material in the protector. The needle's cutting end is thus encapsulated within the protector when the detent mechanism releases the protector from the catheter.

  • Patent number: 5277042
    Abstract: A mechanical anti-theft device of the type applied to the steering wheel of an automotive vehicle which automatically ratchets to it's applied position without necessity of key lock actuation is provided with several security enhancing features which cumulatively prevent or make the device exceedingly difficult to unlock using conventional burglary tools or lock picking techniques. The features include configuring the ratchet teeth of the telescoping rod member in a way which minimizes any attempt to deactivate the lock unless the key is used. In combination with the ratchet teeth configuration, the lock pawl mechanism is configured to include an arcuate, transversely extending apex edge line or surface which cooperates with or is sized to be coincident with the rod members circumference to prevent a wedge, shim or pick from being readily easily inserted between pawl and ratchet tooth to force a retraction of the pawl.

  • Patent number: 5278537
    Abstract: An electronic alarm is disclosed for use in a moving vehicle which generates ultrasonic sound for preventing animals from moving into the path of the vehicle. The device includes a simplified driver circuit for generating electrical impulses in the form of square waves having constant peak-to-peak voltages. The driver generates the square waves with periodic, sequentially increasing wave frequencies followed by sequentially decreasing wave frequencies. A coupling transformer converts the square waves into electrical sine wave voltages having high peak-to-peak voltages to cause a piezo-electric transducer to emit intense, ultrasonic sounds of periodically increasing frequencies followed by periodically decreasing frequencies simulating the warble effect of a siren without excessive heating and premature failure of the transducer. The ultrasonic warble effect confuses the animal to prevent inadvertent movement by the animal into the oncoming vehicle's path without injury to the animal.
