  • Patent number: 4486369
    Abstract: Foam extrusion apparatus and methods employing a vacuum chamber at reduced pressure into which foamable material is continuously extruded, hardened and cut to length, means for inventorying a plurality of successively cut lengths in a second chamber then at such reduced pressure, and means for discharging the inventory from the second chamber to the outside after the second chamber has been brought to atmospheric pressure without affecting the reduced pressure in the vacuum chamber. Stacking devices are employed to inventory the cut lengths in either a vertical or horizontal stack for transfer as a stack into and/or out of the second chamber. Provision also is made for accumulating the boards in close but spaced facial relationship with substantially the entire surface areas of the cut lengths exposed to the reduced pressure prior to stacking and discharge to the atmosphere.

  • Patent number: 4484792
    Abstract: A modular electrical connector system provides relatively high density pin out capability for high speed signal transmission and coupling while maintaining discrete wire capability. The system includes plural cable terminators, plural connector blocks, each having plural cells to receive and hold respective terminators with the contacts thereof aligned for connection with further contacts inserted to engage the same, and a frame to hold the connector blocks securely in relative position to each other. Each cable terminator includes one or more contacts for electrically connecting with the cable conductor, electrical insulating molded about the junction of the contact and conductor, and a flexible locking mechanism to facilitate locking and removal of the terminator from its connector block cell, preferably from the back thereof, without disturbing other terminators in the connector block.

  • Patent number: 4484360
    Abstract: A shin guard and a method of making it are disclosed. The shin guard has a rigid outer shell of polyurethane and a polyurethane foam backing. A recess is formed in the foam backing by pressing in a hot die having the profile of the recess to be made. The recess is oblong and centered over the shin bone or tibia. A dense, modified polyurethane is then cast in the recess. The combination of polyurethane foam and dense, modified polyurethane provides excellent shock absorption in a light weight shin guard.

  • Patent number: 4484561
    Abstract: A gas-fired convection oven for processing food, for example, having a fan for moving air along a circulatory path over, along and about the food to be processed. A package type gas burner outside the oven is directed into a heat exchanger tube of substantial length extending into the oven. High-temperature exhaust gases are discharged from the burner to be directed through the heat exchanger into the circulatory path of air flowing through the convection oven. Relatively proximate the burner the heat exchanger has a linear portion that is of elliptical cross section, and that portion is oriented with respect to the outlet of the convection blower and walls of the convection blower chamber to draw air over substantially the entire surface area of such portion for maximum cooling/heat exchange function with respect thereto.

  • Patent number: 4483236
    Abstract: A pneumatic throttle control configuration provides synchronized start-up and independent shut-off of multiple pneumatic tools. Each tool includes a throttle control assembly having a manually operable throttle valve which selectively admits air to the vane motor of the tool and a spring-biased piston operably coupled to the throttle valve which maintains it in an open position in response to air pressure in a control line which interconnects the tools. The vane motor includes a governor controlled valve which opens at a predetermined motor speed and provides air to the control line and the pistons of each tool of the multiple tool arrangement, thereby opening every throttle valve. Each pneumatic tool may then operate and stall independently. When the last tool stalls, the control air flow to all tools is terminated and the throttle valves close.

  • Patent number: 4477048
    Abstract: A point of purchase flexible pad holder and display includes an upper clear plastic section which may snap into a pricing channel or be suspended from a peg and a lower separable double-sided, front and back, adhesive section with the front of such section being employed to secure a tear-off pad while the back may secure the holder as a whole or separated in a variety of display locations. The connection and structure of the two sections enables stable support of the pad, ease of insertion into the pricing channel, and also ease of clean separation of the two sections. The back may also secure a second pad so that when the first is exhausted the holder need merely be turned around on the pricing channel or peg to present the second pad to the purchaser.

  • Patent number: 4476162
    Abstract: Coating of the convex side of an optical lens for blocking purposes by spinning the lens about its vertical axis and dipping its downwardly facing convex side in a liquid coating material, stopping the rotation of the lens and upwardly withdrawing the lens above the level of the coating material, and spinning the upwardly withdrawn lens to spread the coating material by centrifugal force as a uniformly thin film over the convex side and to drive the film sufficiently for handling.To facilitate the lens coating operation, the lens is held on its upper concave side by a suction cup having the upper end of its vibration damping stem chucked in the drive shaft of a hand held motor housing. To further facilitate the lens coating operation despite leakage between the suction cup and the lens, the drive shaft has a passage therethrough communicating with a passage from the suction side of the suction cup through the stem and with a flexible suction tube leading to the suction port of a power vacuum motor.

  • Patent number: 4473963
    Abstract: Apparatus for releasably attaching a sign to a display stand. The sign comprises a sheet of material folded into a central section and a pair of upstanding display sections. The sign support inludes a pair of pivotally connected support members. One support member is releasably attached to the support surface and supports the central section of the sign. The other support member engages the display sections of the sign and maintains them in an upright orientation relative to the support surface. Mating catches on the support members secure the support members to each other in order to securely engage the sign. The engagement between the mating catches may be released in order to pivot the support members relative to each other so that the sign may be removed from the sign support, without removing the sign support from the support surface. The sign support is preferably formed as a unitary, molded plastic article.

  • Patent number: 4473973
    Abstract: A gutter system characterized by a continuous snap lock hinge connection between a gutter and hanger therefor which allows the gutter and hanger to be relatively angularly adjusted in the field for use with different roof configurations, and which then is secured against hinged movement by bonding to provide a continuous rigid support for the gutter as well as a continuous water seal between the gutter and hanger. The hanger includes an anchoring flange having a reversely under-turned edge portion forming a hook; whereas each of the gutter side walls has an inwardly-turned top edge terminating at an enlarged bead adapted to be transversely snapped into the bight of the hook for hinged movement therein. The interengaged hook and bead allow the gutter and hanger to be relatively angularly adjusted as desired until an adhesive interposed between mating surfaces thereof sets or cures to form a rigid bond that holds the gutter and hanger in the desired adjusted angular relation.
