Abstract: A protective dispenser for dispensing serially arranged sheet materials, includes a container bounding an open-ended internal chamber for receiving the materials. A partitioning wall spans the internal chamber and supports the materials. The partitioning wall has an opening for the successive passage of the materials therethrough. The partitioning wall is disposed at a distance from the open end of the chamber so that a skirt region of the container that surrounds the open end provides an environment that is sheltered from the elements for the materials to emerge into after passing through the opening. The skirt region may be provided with an aperture for the passage of the respective material therethrough from the sheltered environment to the outside of the container. A channel may be formed at the exterior of the container, leading from the aperture all the way to a free end of the skirt region.

Abstract: A forefinger sheath and/or a thumb sheath of a glove worn on a player's power hand are stiffened to prevent the tips of the forefinger and thumb from curling toward and pressing against each other and activating muscles that would otherwise ruin a swing of a sports implement, such as a golf club. A strap is also used to immobilize the thumb in the thumb sheath.

Abstract: A fail-safe, automatic interlock connector arrangement automatically electrically interconnects an electrical component on a wing to another electrical component on a fuselage of a radio-controlled model airplane at the same time that the wing is connected to the fuselage.

Abstract: A keeper for detachably attaching the two ends of a length of flexible linear solid chain, such as a necklace or a bracelet, to each other. A spherical ball at one end of the chain is inserted into a deformable clamp which is attached to the other end of the chain. The clamp has two arms which detachably engage the ball. A frusto-conical keeper element is freely mounted about the chain length adjacent the clamp; the keeper element converges and tapers away from the clamp, so that when the clamp with engaged ball is displaced into the keeper element by concomitantly pulling the keeper element and the other end of the chain away from each other, the clamp and engaged spherical ball are tightly fitted into the keeper element. The outer surface of each curved arm of the clamp thus engages the inner surface of the keeper element, so that the two chain ends are detachably attached to each other, and cannot be separated from each other, except by pulling the one end of the chain length away from the keeper element.

Abstract: An improvement in post-type earrings, which are earrings connected to a human ear by a rigid slender short rod or post which extends from an ornament, and is rectilinear and cylindrical. The post is threaded at the end opposite to the ornament, and a clutch having a conical configuration formed by a concave base and a plurality of radial springy fingers is provided. The clutch is pushed onto the post, whereby the tips of the fingers engage the convolutions of the helical threading, and the clutch may only be removed by unscrewing it off of the post. The present clutch configuration features a terminal tip of each springy finger having a terminal lip portion which diverges away from the direction of curvature of the finger, so that the lips define, in combination, an opening from which the springy fingers extend radially, and through which the post is threaded when the earring is mounted to the ear.

The post is threaded at the end opposite to the ornament, and a clutch having a conical configuration formed by a concave base and a plurality of radial springy fingers is provided. The clutch is pushed onto the post, whereby the tips of the fingers engage the convolutions of the helical threading, and the clutch may only be removed by unscrewing it off of the post. The present clutch configuration features a concave base for self-locating of the post; an octagonal base perimeter for facilitating grip and unscrewing; convex rounded tips on the fingers; a center longitudinal ridge on each finger for increased strength and less weight; lateral end ridges adjacent the finger tips to prevent degradation or bending of the tips; and lateral base ridges on each finger which improve flexibility.

Abstract: An improvement in post-type earrings, which are earrings connected to a human ear by a rigid slender short rod or post. One end of the post is attached to an ornament. The post is rectilinear and cylindrical and extends from attachment to the ornament. In service, the other end of the post is pushed through an opening in a person's ear, and a suitable element is attached to the other end of the post to secure the earring on the ear. In the present invention, at least a portion of the outer surface of the post has a helical threading. The element used to secure the post on the ear is a clutch having a central opening about which are radially arrayed a plurality of spaced apart springy fingers. The fingers extend to terminal attachment to a base portion of the clutch. The clutch is engageable by the post by extending the post axially through the opening in the clutch, until the tips of the springy fingers pass over the convolutions of the threading and are held in the threading.

The element used to secure the post on the ear is a clutch having a terminal first central opening about which are radially arrayed a plurality of spaced apart springy fingers. The fingers extend to terminal attachment to a disc-shaped base portion of the clutch having a second central opening.
