An accumulator for storing rows of articles thereon includes a frame having upper and lower shafts rotatably supported thereon. A plurality of sprockets are mounted on each of the upper and lower shafts for rotation therewith. Each of the sprockets defines a radius. An electric motor is provided for selectively rotating the shafts and the sprockets mounted thereon. A plurality of roller chains are mounted on associated pairs of the upper and lower sprockets for movement when the shafts and sprockets are rotated. Each of the roller chains includes a plurality of spaced apart pins. A plurality of link are carried on each of the roller chains for movement therewith. Each of the links has a pair of apertures formed therethrough and a pair of arcuate slots formed therethrough. The apertures and the slots having respective first edges which define a straight line and respective second edges which define a radius. The radius defined by each of the links is substantially equal to the radius defined by each of the sprockets. Lift rails and lift finger subassemblies are secured to each of the links which define shelf positions for supporting rows of articles thereon. The lift finger subassemblies are oriented at a small angle relative to the links to retain the articles on each of the shelf positions.

A method for obtaining improved release of a polymer from a contacting surface by incorporating a reactive internal release agent in the polymer reaction mixture is disclosed.
摘要:
An improved and laminated antenna window for vehicles and the like in which antenna wire is embedded in interlayer material and extends out of a surface of the interlayer material into a notched area for attachment to an electroconductive element adapted to be coupled to a radio receiver. A thin layer of a plastic material having a lower deformation temperature than the interlayer material is used in the vicinity of the notched portion to provide a barrier against fluid penetration between the layers of the assembly to be laminated, thereby insuring a product that is acceptable to the customer.

A vehicle barrier system, comprising, a support member having a first side disposed toward an area used by vehicles, a splice plate including a support aperture and a stress concentrator associated with to the support aperture, and a rail assembly including, in one embodiment, a wood rail and a first side, wherein the first side of the rail assembly is coupled to the splice plate and the splice plate is coupled to the support member at the support aperture. In another embodiment the rail assembly includes one or more weakened areas serving as stress concentrators in the rail assembly.
摘要:
A method and apparatus for controlling a charge/discharge voltage applied to an EC device to ensure that an appropriate voltage drop across the EC device is maintained during charge and/or discharge modes of operation. The appropriate voltage drop is determined with respect to a temperature measurement proximate the EC device. The charge level of the device is monitored using a coulomb counter circuit having a topology designed to minimize interference in the operation of the EC device.

A device and method for forming a composite from a pair of parts via suspension lamination is disclosed. The device bonds members with opposed mating surfaces and has a base and a vertical column mounted on the base. The vertical column supports a vertical cylinder. A vertically adjustable head assembly for holding an upper part is located at the lower end of the vertical cylinder and is operatively connected to a drive motor at the upper end of the vertical cylinder. A vacuum generator generates a negative pressure to hold the upper part on the head assembly. A nest member is located below and coaxially with the head assembly for supporting a lower part. The upper and lower parts are optionally laterally aligned via an alignment means and a curing medium is provided to the aligned parts to cure an adhesive composition which is spread over the opposed mating surfaces of the parts to form a composite of the parts. Curing occurs while the lower part is suspended from the upper part via surface tension.
