Abstract: Tires each having a tread pattern comprising sub-grooves diagonally disposed in the same direction are fitted on the left- and right-hand sides of an automobile such that imaginary lines extending respectively from the sub-grooves of the left- and right-hand tires of the same axles intersect each other on the front side of the automobile for the dry road running, while the imaginary lines intersect each other on the rear side of the automobile for the wet road running.

Abstract: A plastic tube is cut into two sections which are sealed closed by a sterile method wherein the tube is loaded into two clamping jaws which flatten the tube. The tube is cut through the flattened section and the cut ends are heated to their molten state. A wafer having wings is located between the cut ends with the wings penetrating the lumens to create an internal plug as the wings force the molten material inwardly. The plugs add to the strength of the resultant seal. If desired, the molten ends are pressed into a cavity which is cooled to a temperature below the molten temperature to seal the ends. The tubes are then removed from the cavity. When it is desired to connect individual tube sections the two tube sections are placed in clamp members in axial alignment slightly spaced from each other. The ends of the tube sections are melted by a melt/wipe process and the tube sections are then pressed into contact with each other to be welded into an integral tube.

A polymer adhesive is disposed intermediate the glass layer and a substrate layer such that adjacent substrate layers are bonded together. By controlling the height of each pair of substrate and glass layers, a precisely spaced and strongly bonded stack of substrate layers is formed.

Abstract: A pultrusion machine employing a corrugated impregnator vessel to immerse multiple, continuous strand, fiber tow in an impregnating material, and an adjustable metered exit orifice for the impregnator vessel to control the quantity of impregnating material retained by the impregnated fibers, is provided. An adjustable height insert retains transverse rod elements within each depression of the corrugated vessel to maintain the individual fiber tows spread and in contact with the vessel bottom. A series of elongated heating dies, transversely disposed on the pultrusion machine and having flat heating surfaces with radiused edges, ensure adequate temperature exposed dwell time, and exert adequate pressure on the impregnated fiber tows, to provide the desired thickness and fiber/resin ratio in the prepreg formed. The prepreg passing through the pulling mechanism is wound on a suitable take-up spool for subsequent use. A formula is derived for determining the cross sectional area opening of the metering device.

Abstract: Apparatus for translating objects along a path is constructed in a manner which automatically conforms surfaces of a guideway with adjacent surfaces of a rail that extends along the guideway and thereby realizes very precise travel. A housing containing the guideway initially has a channel that is broader than the guideway. Plates are loosely disposed in the channel and strips of resilient material extend from the plates to the channel walls. The rail is emplaced between the plates and a cover plate is secured to the housing over the rail. This wedges the plates apart and compresses the resilient material while causing the top of the rail to be strictly parallel with the cover plate and while causing the plates to be strictly parallel with the rail side surfaces. Hardenable liquid adhesive is injected into the channel to unitize the plates with the housing.

The system includes a label printing station, a label applying drum, and label stripper means including a stripper blade having a free end disposed adjacent the drum and about which the substrate is guided so as to undergo a relatively abrupt reversal in direction. A substrate tractor drive downstream from the stripper blade normally pulls the substrate under tension about the free end of the stripper blade to effect release of labels from the substrate for application to predetermined envelopes, the substrate tractor drive being selectively operable to create a substrate loop path immediately downstream from the free end of the stripper blade to prevent release of an incorrect label from the substrate.

Abstract: A process for joining variously shaped vacuum heat insulating elements having edges adapted to be butted against each other or to overlap each other. A bellows is tightly connected with each vacuum heat insulating element in the area of its edges, the free edge of the bellows projecting beyond the element. The heat insulating elements are positioned such that the edges of the bellows rest against one another in an aligned manner or overlap, and the bellows are tightly connected with one another. The heat insulating elements are then moved against one another until their edges rest against one another or overlap, and are tightly connected with one another. The gap at the joint formed between the heat insulating elements and the bellows is evacuated and closed off tightly.

Abstract: A method of making a golf club includes the use of an inner tube, which is made of an elastic and refractory material and is wrapped orderly onto with at least a matrix layer of thermoplastic material and with at least a reinforcing layer of long fiber material so as to form a tubular body having a laminated outer shell. The tubular body is heated in a molding tool up to a temperature corresponding to the melting point of the thermoplastic plastic material. A pressurized gas is introduced into the tubular body to force the molten thermoplastic plastic material to diffuse evenly into the interstices of fiber bundles making up the long fiber material. After being cooled, the molding tool is opened to remove therefrom the golf club made of plastic composite material. Such golf club is tough, light in weight, and has an excellent shock-absorbing quality.
