  • Patent number: 5837294
    Abstract: Windshield repair tool has an injector for injecting liquid resin into fractures and pits in broken windshields. The injector has an injector cylinder and a plunger that applies pressure to resin in the cylinder for injecting the resin into the fracture or pit. The plunger itself includes an outer sleeve and an inner plunger component biased forwardly in the outer sleeve by a coil spring. The pressure on the resin is monitored and can be controlled according to the amount that the plunger stem projects from the outer end of the plunger sleeve. This avoids insufficient or excessive filling of the fracture or pit.

  • Patent number: 5834040
    Abstract: A braiding extruder for making braided products from extrusible material. The braiding extruder includes a first rotatable member, a second rotatable member, a rotatable member driving system, and an orifice blocking arrangement. The rotatable members each include a pair of orifices for extruding a strands of extrusible material therethrough. The orifices are fluidly coupled to a source of pressurized extrusible material. The driving system rotates the first rotatable member clockwise about a first axis of rotation, and rotates the second rotatable member counter-clockwise about a second axis of rotation, parallel to the first axis of rotation. The orifice blocking arrangement selectively permits and prevents the extrusion of the extrusible material from the orifices. The orifices, the driving system, and the orifice blocking arrangement extrude and braid at least three strands of extrusible material.

  • Patent number: 5820799
    Abstract: A process for making a marble casting material using a solidified polymer blend having superior depth characteristics. The process involves the partial intermingling of two or more partially incompatible marble casting resins that are not intended to be normally used in combination. Due to the partial incompatibility, when the partially intermingled marble casting resins solidify, a marble effect is created.

  • Patent number: 5814351
    Abstract: An applicator for drywall mastic can alternatively cover flat drywall joints, outside corner drywall joints, or simultaneously both outside corners on a stub drywall, all with little or no manual adjustment of the applicator. A spring biased lever is pivotally mounted on each side of the applicator. Normally, the bias extends a projection on the lever which rides over the edge of the outside corner in order to guide and direct the applicator as it moves along a corner wall. A circumferential flange on a wheel cooperates with the projection to give greater stability. If the applicator is pressed against a flat wall, the projection is pushed back against the bias of the spring so that the projection has no effect.

  • Patent number: 5804221
    Abstract: An air ring for supplying cooling air to a hot extruded plastic film after the film has been extruded from an annular extrusion die at an elevated temperature has an annular body which surrounds the tubular film after the film has left the extrusion die. The body has a circumferentially extending air passage through which air can be supplied from an external source and which directs cooling air from the passage between the body and the film with a venturi-like effect. A circumferentially extending series of individually operable actuators are each operable to vary the venturi-like effect at its circumferential location and cause the film to become nearer to or further from the body at said location to cause the thickness of the film at said location to decrease or increase.

  • Patent number: 5800844
    Abstract: A dough press machine for flattening a quantity of dough usable as a crust for a food product such as a pizza pie. The machine has a vertically movable upper platen having a bottom surface and a lower platen having a top surface. The lower platen is movable from and to a position whereby the bottom surface of the upper platen and the top surface of the lower platen are substantially aligned with each other for vertical downward movement of the upper platen against the lower platen. The machine includes a sensor for detecting alignment of the lower platen with the upper platen such that the upper platen is vertically immovable when the lower platen is not in substantial alignment with the upper platen. Vertical movement of the upper platen is accomplished electromechanically with an electric thrust actuator in communication with the upper platen.

  • Patent number: 5788998
    Abstract: The invention relates to an adjustable throttle with which to influence the mass flow within a rectangular flow channel or a flat flow channel with rounded marginal areas. Because of its special design, the throttle has no parting plane perpendicular to the fluid flow direction. The channel height may be modified by this throttle, so that the fluid mass flow may be influenced by changing the local flow channel resistance as a function of its width without creating discontinuities in the flow channel. Because of this continuous change in the geometry of the flow channel, both in the direction of its width and in the flow direction, the whole flow channel is totally free from dead spots.
