Abstract: A technique for creating "universally" calibrated dental articulators includes using a replica which simulates upper and lower dental models of a patient to properly align mounting plates to an articulator. The mounting plates are releasably attached to the replica before upper and lower frame members of the articulator are closed about the replica and fixed to the mounting plates. The replica is then detached from the mounting plates and used to form additional articulators identically calibrated with mounting plates. Base plates releasably attachable to the mounting plates are then used to form and mount the dental models. A first base plate is fixed to a first dental model and is then releasably attached to a mounting plate on the articulator. A second base plate is then releasably attached to the opposing mounting plate on the articulator.

Abstract: A window shade comprising a base sheet-like material, such as a fabric, (1) which hangs vertically from a roller and to which is attached, by parallel narrow attachment means at intervals, a second sheet-like material of a decorative character (3) which is longer between its attachments (2) to the first material (1). If there is sufficiently excess decorative material (3) between lines of attachment (2), it folds twice between lines of attachment (2) when such a shade is rolled up. When the shade unrolls, the decorative material (3) flexes out from the base material (1) because of its greater length and forms an air-filled cell. Vertically arranged strips of these cells (18) may be formed on a single base sheet, with each strip unique in various ways to obtain a decorative effect. The shades may also be made of strips of material running the width of the shade. Decorative material which does not crease or fold tightly may be attached to the face of flexible material on a cell-by-cell basis.

Abstract: A hand glove includes markings formed thereon which, when worn by a wearer, provide the wearer with a visual indication of the proper gripping position of an implement, such as a golf club or a baseball bat. By aligning the implement with markings formed on the hand glove, a proper gripping position of the selected implement can be obtained.
