  • Patent number: 6526682
    Abstract: A fastening system and method to secure a light panel to the rear of a picture frame through the use of dual locking refittable fasteners in combination with retainers of the frame. The versatile thin illumination assembly system, consisting of the combination of the light panel and mounting system, can be applied to most existing display frames, thus converting a non-illuminated picture frame to an illuminated picture frame. The system when coupled with a frame creates an open backing that maintains the original light panel housing and eliminates heat buildup or dissipation complications often experienced with closed mounting systems. The mounting system and method requires no additional tools for the assembly process, and the resulting frame assembly is thin and easy to assemble.

  • Patent number: 6494390
    Abstract: A method of making polymeric particulates wherein polymeric scrap material such as in the form of film waste is supplied to intermeshing pulverizer screws which are rotated to transport the polymeric material along their length and subject the polymeric material to solid state shear pulverization and in-situ polymer compatibilization. Uniform pulverized particulates are produced without addition of a pre-synthesized compatibilizing agent. The pulverized particulates are directly melt processable (as powder feedstock) and surprisingly yield a substantially homogeneous light color product. The polymeric film waste containing high proportions of LDPE yield molded articles of superior notched izod impact strength and elongation. Compatibilized polymeric particles can be formed even if the polymeric scrap material includes cellulose materials such as paper, cardboard and wood.

  • Patent number: 6481768
    Abstract: A ball-picking device is used to pick up a ball on a ground surface, and includes a basket frame unit which confines a ball receiving space and which has a ground contacting side formed with a plurality of ball-extension gaps that are in spatial communication with the ball receiving space. Each of the ball-extension gaps is confined by a pair of deformable rod units, and is slightly narrower than a diameter of the ball such that when the ground contacting side of the basket frame unit is moved toward the ground surface to register the ball with one of the ball-extension gaps, the deformable rod units that define a respective one of the ball-extension gaps will be pushed apart and will be deformed by the ball so as to enlarge the respective ball-extension gap and permit extension of the ball into the ball receiving space.

  • Patent number: 6481109
    Abstract: A control system is provided for a pivotally actuated tracer which traces an object (e.g., a frame mount of an eyeglass frame, a lens, or a lens pattern) while the object is held in a more-vertical-than-horizontal orientation. The control system comprises a trace control element and a gravity compensation element. The trace control element applies control signals to the pivotally actuated tracer. In response, the object engager of the tracer is pivotally actuated against and along the object to be traced with a biasing force toward the object. The gravity compensation element is adapted to compensate for the effects of gravity on the object engager by causing a varying pivoting force to be exerted on the object engager. The pivoting force varies depending on the rotational orientation of the object engager to keep the biasing force substantially constant along the object. Also provided is a data acquisition system for the tracer.

  • Patent number: 6479003
    Abstract: A method of making polymeric particulates wherein polymeric scrap material, virgin polymeric material and mixtures thereof are supplied to intermeshing extruder screws which are rotated to transport the polymeric material along their length and subject the polymeric material to solid state shear pulverization and in-situ polymer compatibilization, if two or more incompatible polymers are present. Uniform pulverized particulates are produced without addition of a compatibilizing agent. The pulverized particulates are directly melt processable (as powder feedstock) and surprisingly yield a substantially homogeneous light color product. The pulverized particulates also can be more intimately mixed than mixtures which are provided by only melt mixing, and can be melt processed without a significant delay in achieving phase inversion. The pulverized particulates also provide a stable microstructure.

  • Patent number: 6461676
    Abstract: A semi-finished wood simulating product and method is disclosed. The product is manufactured by providing a substrate having at least one surface to be finished. A liquid basecoat is applied on the substrate and dried. A wood grain pattern is deposited, in liquid form, on the basecoat. Some of the pattern is transferred from the originally deposited position on the basecoat to a subsequent position. The pattern is then cured. A polymerizable protective coating is applied onto the substrate overlying the basecoat and the pattern. The protective coating seals the substrate and is adapted for accepting a colorant to be applied by an end user. The protective coating is then polymerized. Additionally, if a porous substrate is provided, a sealer is applied prior to the liquid basecoat and is then cured.
