  • Patent number: 4335738
    Abstract: A butterfly valve is disclosed for use in controlling the flow of gaseous fluid under high temperature, high pressure conditions. The interior of the valve body has non-overlapping semi circular valve seats spaced to either side of the shaft for the valve disc. The valve disc is rigid and inflexible throughout and, when closed, its periphery terminates close to the interior of the valve body under all operating temperatures. When the disc is closed, the semi-circular valve seats cooperate with the recessed rigid periphery of the disc to form a chamber chargeable with purging fluid at a higher pressure than the fluid on the upstream side of the valve and effective to prevent flow of the latter past the valve disc.

  • Patent number: 4326345
    Abstract: An article of footwear which comprises a ringlet of elastic webbing forming the upper thereof with its lower longer edge embedded in elastomeric composition which takes a set at low temperature to form a unitary sole and heel inseparably bonded to the upper. If the sole is made to be worn over athletic shoes of the type equipped with spikes or cleats, the interior of the sole is molded to provide cavities accommodating such spikes or cleats. The rims of these cavities bear against and support the rim areas of the sole and heel of an athletic shoe thereby preventing the spikes from penetrating the sole of the footwear. The elastic webbing is tailored to shape merely by forming a dart crosswise of the midportion of the toe end thereof.

  • Patent number: 4312436
    Abstract: Validator-controlled apparatus responsive to the inspection and validation of a plaque as genuine cooperating with a timer to control the power supply to and operation of a plurality of electrical components for one or consecutive predetermined periods. In an illustrative application of the apparatus, the validator inspects and authenticates a coded plaque of paper currency or a coded card as a prerequisite to the control and use of a room for a measured period of time equipped with one or more electrical components. One of the controlled components is a lock for the room door or barrier which re-locks after entrance of the patron or patrons and remains locked from its exterior but is manually releasable from the interior at any time. The apparatus includes provision for disabling the plaque validator and the door lock during the decrement of an existing predetermined time period.

  • Patent number: 4304378
    Abstract: A bag holder for holding a plain bag in an open position for filling by supporting in a cuff at the bag opening has a bag support with improved cuff attachment means without accessory bands or clamps for obtaining quick installation and secure retention of the bag, including those made of slippery plastic film. In one construction of the bag support, resilient tensioning means provides nearly constant low force peripheral tensioning of the cuff by three corner grips of appreciable area. Each corner grip has a smoothly curved initial grip surface for holding the outer fold of the cuff tensioned over a smoothly curved snubber grip surface thereby holding the cuff with a self locking action. A grip surfacing on the grip surfaces provides a high grip coefficient for obtaining self locking of the snubber grip when a bag load is applied.

  • Patent number: 4301994
    Abstract: An improved bundle conductor stringing block having a main frame constructed essentially of structural steel components and including a cantilever suspension yoke positioned to form a tow-line receiving passage through which a helicopter can dispense a conductor tow-line onto a central one of multiple sheaves. Guide members pivoted to the opposite sides of the tow-line passage guide the tow-line onto the central sheave and include toggle spring device engageable by a running board at the trailing end of the tow-line to engage these members and pivot them in either direction to retracted positions along the block side frame.

  • Patent number: 4295908
    Abstract: Radio frequency heat sealing method and apparatus for simultaneously fabricating a plurality of separate items from separate sets of continuous plastic strips or sheets as these sets are indexed in unison past a heat sealing station. The technique utilizes a platen equipped with heat fusing and tear sealing dies on its opposite faces and which platen is located between separate sets of plastic strips and a pair of cooperating platens. The die equipped intermediate platen is preferably cooled to permit rapid cycling and indexing of the sets of stripping therepast.

  • Patent number: 4283091
    Abstract: A shock and vibration-proof fastener of general application and particularly suitable to hold dual wheels demountably assembled to a cargo vehicle hub. The fastener is designed to isolate the threads thereof from radial and torsion stresses utilizing a split collet encircling the shank of the fastener with its periphery converging toward the collet ends at angles of the order of 4 to 1 relative to the collet axis and having a nesting interference fit with a similarly tapered bore through the parts or wheels to be clamped together. The fastener shank has a threaded well in one end mateable with a cap screw having a self-aligning conical surface on the underside of its head engaging the rim edge of a loose fitting washer. The self-aligning surfaces are preferably provided with a ring of teeth and notches interengaging along helical surfaces having a pitch substantially greater than that of the fastener threads.

  • Patent number: 4278132
    Abstract: Apparatus for introducing a widely variable predetermined quantity of liquid from a non-pressurized source into a flowing stream of a pressurized fluid. The unitary apparatus is readily detachably assembled to bulk shipping containers of different sizes and its pneumatically powered proportioning mechanism is quickly adjustable at will to pressurize and dispense a liquid at a selected one of many different precise rates into a pressurized fluid stream. The apparatus is readily and quickly adjusted to operate at a wide range of pressures and at many hundreds of pounds per square inch and to vary the ratios of the two fluids between one part in 1,000 and one part in 40,000. The proportioner has many applications including dispensing a fire fighting agent into a pressurized water line supplying fire hoses.

  • Patent number: 4278237
    Abstract: An apparatus and method of automatically threading successive closed framed openings by helicopter towing a line equipped with a separable coupling. The invention utilizes a short cable loop pre-threaded through each closed frame such as the throat of a stringing block which cable loop is provided at its ends with coupling halves releasably supported at the opposite ends of a trough overlying the framed opening to be threaded. A helicopter is manoeuvred to drop the towing line coupling into a trough where its halves are automatically separated and thereafter recoupled to a respective end of the cable loop. Subsequently, the forward coupling can be similarly separated for insertion of a second cable loop in the towing line at the next threading apparatus in the helicopter's path of travel.

  • Patent number: 4274296
    Abstract: A self-centering, self-aligning, anti-friction power transmission mechanism comprising a rotor cooperable with a screw to convert rotary movement to linear movement and vice versa. The rotor has one or more convolutions of rollers having their axes arranged in a helical path of the same pitch as the screw thread with their inner ends positioned to have non-scuffing, non-slipping rolling line contact with the screw thread, a result obtained by off-setting each roller axis downwardly along the helix from the line of contact by a distance such that the line of contact and the rotor axis lie in a common plane parallel to the roller axis. The screw thread is preferably of the Acme type with a sidewall taper initially slightly less than the taper of the roller ends in contact therewith whereby, in use under load, the rollers cause cold flow and work hardening of the thread sidewall thereby substantially increasing the length of the line of contact between the rollers and the screw thread.
