  • Patent number: 4320384
    Abstract: A compound pendulum allows light to impinge upon properly positioned acceleration or deceleration photocells to vary the resistance of the photocells in accordance with the angular displacement of the pendulum; the amount and direction of angular displacement of the pendulum is dependent on the amount of acceleration or deceleration of the vehicle. Variation of the deceleration photocell resistance varies the frequency of an oscillator circuit to alternately flash a pair of warning lights at a frequency dependent on the rate of deceleration of the vehicle. The acceleration photocell must receive maximum illumination (a threshold value) to actuate a light for warning of a minimum rate of acceleration of the vehicle. A manual switch allows a high flash rate of alternate warning lights to be controlled by the operator of the vehicle.

  • Patent number: 4317641
    Abstract: A first support member having a web with a slot and a pair of second support members having locking connectors insertable through the slot in side by side relation, each connector having a resiliently yieldable finger engageable against the web after insertion through the slot for interlocking the first and second members. Each connector has a laterally projecting detent on the side opposite the finger, an opening providing an arcuate generally vertical shoulder spaced rearwardly from the detent, and a laterally projecting spring retainer on the same side as the detent extending forwardly at least partially across the opening. When the connectors are inserted through the slot in side by side relation the forward end of each connector is confined against the other connector by the retainer thereof with its detent engaging the arcuate shoulder of the other connector, thereby interlocking the second support members, the retainers yielding resiliently to permit passage of the detents into the respective openings.

  • Patent number: 4314554
    Abstract: A method and apparatus for providing germicidal and healing treatment of tissue such as bone wherein an electrode of silver or like material is applied to a living tissue site to be healed, initially a direct voltage is applied to the electrode of a polarity driving the electrode as an anode to release silver ions to create a germicidal environment at the site, and thereafter a direct voltage of opposite polarity is applied to the electrode driving it as a cathode to stimulate healing of the tissue at the site. The apparatus is implanted in the body of a patient, and in one embodiment a battery is connected through a switch to the electrode and a reference electrode, the switch initially connecting the electrode as an anode and thereafter changeable by an external operator such as a magnet to connect the electrode as a cathode.

  • Patent number: 4311231
    Abstract: The drive member actuating rollers of an accumulating conveyor are independently supported by pneumatically inflatable tubing at a regulated pneumatic pressure engaging the drive member against the load carrying rollers to provide a drive force substantially no greater than that required to drive the load. Where the drive force is insufficient to overcome starting friction, the pneumatic pressure is periodically momentarily increased an amount sufficient to provide such drive force. In both cases, holdback force during accumulation is reduced to a minimum by matching the pressure of inflation to the drive force required for the load being conveyed, in a manner avoiding unnecessary excess drive force. In a long conveyor, the center section tubing is deflated during accumulation, to reduce holdback force.

  • Patent number: 4307858
    Abstract: A water-activated canopy release mechanism having a detachable sleeve positioned between the arms of a buckle yoke. The sleeve contains a longitudinal passage having a release piston and bushing positioned therein and supporting the sleeve within the yoke. An explosive cartridge mounted at the piston end is fired by a sensor activated by water of predetermined conductivity and drives the release piston completely into the sleeve and wedges it there, thus freeing the end of the sleeve adjacent the cartridge. Simultaneously, the piston drives the bushing out of the other end of the sleeve and against a wedge carried by the yoke arm. As a result, both the piston and the bushing are held in a position which permits the sleeve to drop free of the yoke releasing the canopy from its load.

  • Patent number: 4306316
    Abstract: A disposable bib, napkin or apron of flexible sheet material having a neck cutout in its upper edge portion and two shoulder pieces adjacent the cutout. The upper edge portion carries a pressure-sensitive adhesive capable of releasably adhering to itself and to the clothing or body of a user, the adhesive extending substantially continuously across substantially the entire upper edge portion of the garment, leaving upper side edge portions free of adhesive, and extending downwardly for an appreciable distance to below the cutout. The garment is folded upon itself prior to use with one portion of the adhesive contacting and overlying another portion thereof whereby the entire area of adhesive is covered by the garment itself. To prepare the garment for use, the adhesive-free upper side edge portions are pulled apart to open the garment and expose the adhesive for placement against the clothing or body of a user.

  • Patent number: 4296399
    Abstract: A microminiature palladium oxide gas detector and its method of manufacture. The detector comprises an extremely small coil of extremely fine wire such as platinum which is retained, sealed and insulated with an amorphous ceramic binder. The detector further comprises a catalyst applied to its exterior surface. The detector is manufactured by winding the wire about a mandrel which is desirably molybdenum. The coil is then coated with the binder composition which preferably comprises reduced chromic and phosphoric acids. The binder is then cured to retain the coil and the mandrel is removed by etching or oxidation. The catalyst is then applied which is preferably palladium nitrate in a weakly acidic hydrolyzed solution which has been adjusted to a pH of about 3 with tertiary octyl amine. The catalyst is then dehydrated and calcined desirably using an automatic electronic pulse controlled machine to precisely adjust and control processing temperatures and times.
