  • Patent number: 4579516
    Abstract: This invention discloses a forming roller used in the production of air packaging or dunnage. This forming roller receives heated thermoplastic film brought to the peripheral surface and with vacuum draws this softened film into formed cavities to provide bubbles or blisters in said film. The roller is made of a rapid heat-conducting metal such as aluminum. A shaft providing stiffness is inserted in the roller and fluid conduits in the shaft ends communicate with a counterbore formed in both ends of the roller. Fluid-conducting passageways are drilled in this roller and carry controlled-temperature fluid from one end of the roller to the other. In this same roller is formed vacuum-conducting drilled holes that communicate with the multiplicity of formed pockets in the peripheral surface of the roller. A collector shoe having an arc-shaped cavity is disposed to engage at one time about one-half of the vacuum conductors and is disposed to carry vacuum to these conductors as the roller is turned.

  • Patent number: 4576669
    Abstract: There is depicted and claimed "on demand" apparatus and method for producing air-cushioning material for end-user manufacture. There are two arrangements and both provide economy of apparatus, space, labor and materials. Two thermoplastic film strips are carried from roll storage means to this air-cushioning forming means whereat the webs of film are locally heat-sealed together. A first film is fed to a heated roll whereat this film is heated sufficiently to be thermoformed on a cooled roll with cavities formed therein. These cavities are manifold-connected to a source of vacuum which draws the heated film into the formed cavities. The second strip of film is fed to another heated roll having a resilient covering material with thermoconductive metal powder as a substantial component, thus providing sufficient thermoconductivity and resilience to heat-seal or weld this second film to those areas around the cavities formed in the first film.

  • Patent number: 4571995
    Abstract: A digital readout and display adapted for use with a tank of oxygen under pressure provides pressure regulation, discerning of the pressure in the tank and consumption of the oxygen. A small battery within a case member powers this display. The readout device includes a gauge with a movable element responsive to pressure. An S-shaped rod is carried by and fixed to this shaft. This rod is very light in weight and in a secured condition is free at both ends to prevent friction of moving parts. The discharge end of this light-conducting rod comes in way of a light receiver carried by the body of the gauge. There is a multiplicity of receivers arrayed in a circular pattern near the edge of the gauge body and the light from this rod actuates a reed switch which sends an electrical signal to a microprocessor thence to an LED digital display. A single emitter may be used to send light through three rods each of which is carried by a gauge-type device.

  • Patent number: 4566503
    Abstract: This invention provides an apparatus and method of setting up apparatus for the automatic cutting and/or shaping of IC components carried in a tubular carrier and advanced for processing by gravity. A base plate is disposed at an angle of approximately forty degrees to the horizontal and provides a supporting means for gravitational feeding of these components from a removable U-shaped retainer to a guide and then to a die station. At this die station a resiliently tired feed wheel engages the body of the IC component which is metered and advanced with an intermittent motion. This motion is provided in a timed relationship with two rotating shafts which have pins moved in a precise orbit around a shaft centerline. These pins are one-hundred-eighty degrees out-of-phase with each other. The rotated feed wheel and attached tire are intermittently moved in a strict timed relationship to the movement of the two shafts by a one-way clutch driven by one of the shafts and by an eccentrically moved Pitman arm.

  • Patent number: 4540325
    Abstract: An upstacker jaw clamp and palletizer apparatus in which containers are fed one at a time to an upstacker station and an elevating platform whereat these containers are lifted and at the extreme lift are retained by opposed jaw clamps. These jaw clamps are moved substantially simultaneously to and from retaining condition in response to electronic control signals. The jaw clamps carry pins that are reciprocably retained in bores with forward movement provided by a bias. When a round metal container is palletized, each jaw clamp has two substantially alike pins with blunted forward ends. When the container is plastic with a contoured bottom, the pins are threaded and retain a contoured member. No matter the container shape, the jaw, when moved forwardly, causes the lip portion to move under the elevated container with the pin ends, the contoured member, or the plate disposed immediately above the lip portion and biased forwardly to engage the side walls of the container.

  • Patent number: 4524994
    Abstract: A flowable concrete delivery apparatus is provided in which both rigid and flexible pipe is connected in an end-to-end relationship to provide a high pressure conduit. These lengths of pipe are connected by clamps, each clamp being fixedly secured to a skid that provides a sliding protector for the clamp and prevents unwanted opening and damage to the clamp. The pipe lengths are carried by freely rotating wheels, each having a sleeve that provides a free fit on the outer diameter of a pipe length. The conduit is moved by a hook tool, this tool having one end formed with a handle and the other end with a bifurcated hook that is contoured to releaseably engage the outer diameter of a pipe. An attendant manipulates and moves this hook tool to position and arrange the conduit pipe in the desired delivery position. Although a great convenience, the hook tool is not required by the attendant in every instance as the wheels enable the attendant to grasp and move the pipe conduit when the occasion arises.

  • Patent number: 4505468
    Abstract: This invention pertains to pins carried by and in a retainer head member with the pins actuated when and as the head member and an associated contact member reaches the outermost portion of a paperboard member whereat the pins are caused to move obliquely to this surface and penetrate the paperboard sufficiently to engage and retain the paperboard. These pin ends by latch members are maintained in the desired penetrating position during transfer. This latch is actuated to release the projected pins when transfer is completed. The paperboard is conventionally of corrugated paperboard construction and the extent of pin end protrusion is carefully controlled so that the pin ends in the penetrating position do not protrude and penetrate the rear panel or wall of the paperboard so that only one penetrated paperboard member is transferred. The embodiments shown are adapted for use with paperboard which is not supple or flexible as is cloth or leather.
