Abstract: Eyewear is configured to use pairs of polarized lenses, with one pair held stationary within an eyeglass frame, and the remaining pair disposed adjacent with the fixed pair and permitted to rotate under the control of the wearer. A novel mechanism is included within the eyewear for the wearer to use in rotating the movable lenses with respect to the fixed lenses. In particular, a flexible member is included to surround a majority of each rotatable lens, with the flexible member riding within a channel formed in the frame. A lever, or other type of hand control fixture, is attached to the flexible member. The wearer may than move the lever back and forth, which imparts a linear motion to the flexible member. The linear motion of the flexible member is translated into a rotational movement of the attached lenses, thus creating a wearer-adjustable tint.

Abstract: A mosaic-style art kit is provided. The art kit includes a frame, modeling material, and a guide sheet. The frame includes a peripheral surface operably configured to overlie the guide sheet, and a mosaic-style internal structure having partitions forming cavities for receiving and retaining the modeling material. A front side of the frame is placed on the guide sheet such that the mosaic-style internal structure is aligned with a design on the guide sheet. The design thereby instructs a color of modeling material to be inserted into each cavity of the internal structure. The modeling material is inserted accordingly, and the frame and guide sheet are separated to produce a mosaic-style art product.

Abstract: A concrete forming apparatus having an inside form panel and an outside form panel spaced opposite from the inside form panel to create a gap into which plastic concrete will be placed and cured. A sheet of rigid insulation of a reduced height less than the height of the form panels is placed in the gap. A plurality of tie sleeves are pre-inserted through the insulation at regular intervals. A plurality of form ties are releasably connected to at least one of the form panels and extended through the tie sleeve to support the reduced height sheet of insulation at the desired vertical position. The tie sleeve strengthens the insulation in the area of the form tie and prevents damage to the insulation and prevents vertical movement of the insulation during placement and curing of the plastic concrete.

Abstract: A construction element for limiting a fore part of a formwork consists of a prefabricated element having a width which corresponds to the thickness of the construction work to be erected and a modular length. The element comprises openings for being able to push through reinforcing irons, pipework or the like tubes. Because the element is foreseen to remain in the wall, it is produced preferably with a relatively fine concrete in which a reinforcing mesh of synthetic material is enclosed, which extends also over the openings and prevents the outflow of concrete at the time of pouring the latter into the formwork. Such a shuttering element allows a fast and precise limiting of the formwork in the case the construction work is not poured in one part or is needing recesses for a crane. It requires no cleaning off or pulling off wooden parts when the joining part is produced.

The cassette units may be arranged in a conveyor system for consecutive cooperation with a loading and unloading station, or they may be arranged more or less stationarily for cooperation with means for transporting the moulds to and from the cassette units.

Abstract: A collapsible concrete bulkhead is insertable into a framework. The bulkhead has a pivotable divider plate which is located juxtaposition to a bulkhead plate and moves laterally thereof to reside in an offset base portion of the framework. The bulkhead assembly forms separate concrete sections when concrete is poured into the framework and forms a gap when the bulkhead assembly is removed. Optionally, a liner can be inserted adjacent to the bulkhead assembly and the bulkhead assembly removed before full cure of the concrete so that the concrete fills the void left by the bulkhead with the liner separating the concrete sections.

Abstract: A mounting hub for securing an abrasive grinding wheel to a grinding machine spindle, the hub being formed in a single, integral piece of polymer plastic material. Flanges on each wheel face grip the wheel faces, and a mounting projection provides a spindle bore for receiving the grinding machine spindle. The hub is molded directly on the wheel, resulting in the formation of an interpenetration zone at the hub/wheel interface, in which the abrasive material of the wheel and the polymer plastic material intermix and mesh, producing a strong, durable bond.

Abstract: An improved system is provided for separation of contiguous concrete portions of a structure. This separation is advantageous in reducing structural failure caused by earth settlement, frost upheaval or excessive underground water pressure by allowing each section of an in-ground concrete structure affected to freely float independent of each other, thereby eliminating the effects of stress on the structure. The system has particular utility in forming a deck surrounding a swimming pool and may be used in conjunction with a form which is temporarily secured near the top on the vertical pool wall to receive the concrete forming the pool. The separator system is used at the interface at the top (on the bond beam) of the pool wall and under the deck and comprises an adapter and clip fastener.

Abstract: A system for constructing concrete barriers on a roadway with adequate spacing between sections of the barrier for proper drainage and expansion of the concrete during changing atmospheric conditions. The process utilizes a specially designed positioning tool to leave a proper space in a latice framework of steel rods. A temporary, removeable core or separating section, made of for example a styrofoam inner layer sandwiched between outer layers of "Masonite," designed for this purpose and matched with the positioning tool is inserted into the space and secured there using pins attached to the metal latice works providing an unbroken, constant surface or mold on which to pour concrete for the barrier. When the concrete has set, the core may be collapsed without damaging the concrete or metal frame and removed. When the various cores are removed, the barrier is left with properly spaced and positioned gaps for drainage and expansion of the concrete.

Then a vise which includes jaws having parallel surfaces for engaging the substrate is moved toward the assembly to position a lower jaw under the lower substrate and an upper jaw above the upper substrate.

Abstract: A system and method is disclosed for obtaining precisely registered, articulated castings of upper and lower dental impressions. The dental impressions are obtained through use of a dental tray having a non-porous, bite-deformable central septum. The impression material for the upper dental impression is contained in the upper portion of the tray. The impression material for the lower dental impression is contained in the lower portion of the tray and is supported by a bottom cover which is removed subsequent to placement of the tray in the mouth. As the patient bites, the impression material in the upper and lower portions of the dental tray is molded to the contour of the teeth and gums in their proper relationship with the teeth closed. After the material has set, the tray containing registered upper and lower impressions is removed from the mouth and placed into a mold.

Abstract: A pipe mold for vertically cast concrete pipe includes a cylindrical outer mold case, a cylindrical core spaced inside the mold case, and a pipe-reinforcing cylinder between the core and the case. A system for casting concrete in the pipe mold includes a flat facing ring above the annular space between the mold case and the cylinder. A chute assembly mounted concentrically above the pipe mold includes several radially extending and spaced apart pouring chutes extending downwardly from the center of the chute assembly to corresponding circumferentially spaced apart openings in the facing ring. The pouring chutes channel the flow of concrete into the openings in the facing ring to fill the pipe mold to the bottom surface of the facing ring, which forms a flat annular end section at the desired elevation on the pipe. The facing ring eliminates the need for hand finishing and measuring which is common in the prior art manufacture of vertically cast concrete pipe.
