  • Patent number: 5351366
    Abstract: An improved end clamp for a multi-strand aramid rope has an outer sleeve formed with an internal bore having a taper of between 11/4 degrees and 13/4 degrees. A tapered wedging plug having a taper of between 21/4 degrees and 23/4 degrees is inserted into the sleeve bore and compresses separated equi-spaced strands of the rope therebetween in essentially tangential contact. An annular clearance space is formed between the larger end of the sleeve bore and the larger end of the tapered plug and has an area substantially equal to or slightly less than the area of the aramid material of the rope whereby the separated strands of the rope are in abutting engagement throughout the annular clearance space to increase the holding capability of the clamp. The ratio of the tapered plug length to the diameter of the uncompressed rope varies from about 9 to 1 and 11 to 1.

  • Patent number: 5211283
    Abstract: A reusable plastic package for securely holding and displaying a compact disc. A housing forms a storage compartment having an access opening for receiving and retaining therein a plastic storage box containing a compact disc. A slide plate is mounted on the housing and is slidably moved across the access opening between locked and unlocked positions to retain the box within the storage compartment. The slide plate has locking projections which engage locking tabs on the housing to maintain the slide plate in locked position until released by a manually operated key. A pair of orienting tabs are formed on the slide plate and move through openings formed in a rear wall of the storage compartment and into offset openings formed in the compact disc storage box when the slide plate is moved to the locked position to ensure that the storage box is oriented in the desired position in the storage compartment for viewing of graphics cards contained thereon.

  • Patent number: 4923062
    Abstract: An insert construction for receiving an audio cassette single which is generally contained in a cardboard sleeve and sealed in a clear heat-shrink wrapped plastic cover and which is smaller than the usual plastic case which houses the multiple play audio cassette, enabling the cassette singles to be safely stored and displayed in the security packages heretofore used for the larger plastic cases. At least one generally U-shaped cross-sectional channel is formed in the insert and has a width generally equal to the thickness of an the wrapped audio cassette single for trapping and retaining the cassette within the insert.

  • Patent number: 4903810
    Abstract: An improved clutch shoe of the type that is mounted on the rotor of a centrifugal clutch for coupling engagement with an outer clutch housing. The shoe is formed by two similar L-shaped shoe half sections which are stamped of sheet metal. Each shoe half section has an arcuate-shaped configuration comprising a web and an integral outer shoe table portion with an annular boss formed on each of the webs. A plurality of annular projections are formed to one of the shoe half webs and extend outwardly therefrom in a direction opposite from the annular boss formed on the web. The other shoe half web is formed with a plurality of holes into which the annular projections are press fitted to connect the two shoe halves together with the webs being placed in abutting relationship. The shoe half table portions lie in juxtaposition with respect to each other and form an outer shoe table on which a strip of friction material is attached.

  • Patent number: 4899938
    Abstract: A nozzle adapter is removably mounted on the end of a liquid spray gun to provide a variety of spray patterns and to reduce or eliminate the atomization of the spray liquid. The nozzle adapter is formed by a liquid material discharge member which is removably mounted on the spray gun and an outer pressurized air adjustment member which is removably adjustably mounted on the discharge member. A cone-shaped nozzle of the discharge member projects outwardly through an air passageway formed in a front wall of the air adjustment member. A tubular stream of pressurized air is projected outwardly through the air passageway and surrounds a stream of liquid discharged through an opening in the nozzle tip. Adjustment of the tubular air pattern provides for various liquid spray patterns and varying amounts of atomization of the discharged liquid. The discharge member may alternatively be mounted on a spray gun without the air adjustment member mounted thereon.

  • Patent number: 4850111
    Abstract: A pneumatic control system for a meat trimming knife in which an annular cutting blade of the knife is rotated by a flexible cable driven by an electric motor mounted remote from the knife. An annular diaphragm is mounted in the handle of the knife and is compressed by the manual inward movement of a piston by an operator. The diaphragm is connected by an air conduit which extends along the flexible drive cable to a pressure switch mounted adjacent the electric drive motor. The switch senses compression of the diaphragm and generates an electric control signal which actuates an electric clutch which couples the output shaft of the electric motor to the flexible cable for rotating the cutting blade. The piston is maintained in a diaphragm compressed position by a hand-operated lever mounted on the handle.

  • Patent number: 4559064
    Abstract: A spacer formed of a relatively rigid frame is slidably adjustably mounted on and extends between a pair of horizontally spaced vertically extending ribs of electrostatic precipitator plates to maintain the plates in a predetermined horizontal spaced relationship. The frame preferably is formed by one or two rectangular-shaped frame members having U-shaped hooks attached thereto. The hooks are either attached directly to the plate ribs to frictionally slidably mount the frame between the spaced plates, or connect the two plates together with the plate ribs being clamped therebetween. The frame members and U-shaped hooks preferably are formed of round metal bars. The frame members are mounted on the ribs either at the top or bottom of the precipitator plates and then slidably moved along the ribs until positioned at the desired vertical location.
