Abstract: A feather imping pin with roughened surface is described that attaches a donor feather to a receiving feather. The feather imping pin is inserted into a receiving feather shaft of the receiving feather. Feather imping is performed using the feather imping pin that connects the donor feather and the receiving feather. The feather imping pin fits inside both the receiving feather shaft of the receiving feather and a donor feather shaft of the donor feather.

Abstract: The Cover Keeper is a universal head-cover retention device that keeps golfers from losing head-covers. The bar latching safety pins allows for connection onto any head-cover, as well as switching head-covers in and out with ease. It allows for two head-covers to be connected together or one head-cover to be connected to the golf bag. The elastic cord allows the golfer to take off and put on head-covers with ease. The barrel swivels keep the cords from tangling, especially on windy days. The Cover Keeper badge allows for custom logos, promotional advertising, storage for metal ball markers, and the ability to decorate head-covers with charms.

Abstract: An alloy including at least 6 weight percent aluminum, greater than 6 weight percent nickel, and at least 50 weight percent copper. In some embodiments, the alloy includes 6 to 9 weight percent aluminum, 6 to 11 weight percent nickel, 1.5 to 3 weight percent iron, 1.5 to 3 weight percent manganese, 1 to 3 weight percent silicon, 1 to 5 weight percent tin, and 75 to 80 weight percent copper. The alloy is particularly suitable for jewelry, e.g., wrist watches, and materials exposed to aquatic environments for extended periods of time, e.g., boat hulls and boat propellers.

Abstract: A boutonniere attachment device comprises a backing member and a pin member. The pin member is attached to the backing member and extends from the backing member to a pointed terminal end. The backing member can be engaged with a non-exterior surface of a portion of a garment while a portion of the pin member that includes the pointed terminal end is positioned external to the garment, and while at least part of the portion of the pin member extends at least partially through the stem of a boutonniere in a manner such that a portion of the stem is biased against the exterior surface of the portion of the garment and such that the portion of the garment is biased between the portion of the stem and the backing member.

Abstract: Embodiments of the present apparatus are configured to secure a first member and a second member to one another. The first and second members include a bore extending through at least one of the first and second members and at least partially through the other of the first and second members. The apparatus comprises a pin connector including an enlarged ball portion positioned along a shank. The first member includes an annular groove extending around the bore. A canted coil spring seats within the groove. The apparatus is configured such that the spring exerts a squeezing force on the ball portion when the pin connector is disposed within the bore and the head of the pin connector contacts the second member.

Abstract: A pushpin comprising a pin suitable for penetrating a pin permeable object for frictional engagement with the pin permeable object; a gripping handle on the pin, the gripping handle having a magnet attractive surface so that a magnet can be attached to the gripping handle thereby to allow an object to be displayed to be secured to the gripping handle between the handle and the magnet.

Abstract: Apparatus and method for attaching a covering material to interior components of a vehicle, such as a speaker grille, seat or other substrate. The interior component has a first side configured to face the interior of the vehicle and second side facing away from the interior of the vehicle. One or more anchor members project from the second side of the substrate, each of the anchor members having at least one retention member. The covering material has apertures disposed about a central portion. The covering material is wrapped around the substrate so that the central portion of the covering material overlays at least a portion of the first side, and each of the anchor members and its retention member are inserted through one of the apertures to secure the covering material to the substrate.

Abstract: In accordance with at least one exemplary embodiment, a pushpin retaining device is disclosed. An exemplary pushpin retaining device can include a resilient, elongated pin that can have a first end portion for puncturing and a second end portion. A grip foot can be operatively associated with the second end portion of the pin. Alternatively, a cut edge can be on the second end portion of the pin. A method of retaining objects without object puncture can include providing a pushpin retaining device. The method can also include puncturing a support surface with an end of the pin of the pushpin device and pressing a portion of an object against the support surface with the grip foot or cut edge, respectively.

Abstract: A lock pin with pushbutton-operated axial locking has two locking elements which point in opposite directions and are mounted in radially outwards directed recesses in the body. To ensure a good, wear-resistant pivotal mounting of the two locking elements, combined with good locking action and resistance to shearing, the invention provides that the locking elements create a virtual, freely guided pivoting axis in their connection zone. The result is a pinless mounting of the locking elements.

Abstract: An earring includes a pin adapted to pass through a hole pierced in an ear or other body part. The pin has an enlarged, decorative end thereon which rests against one side of the ear with the pin extending through the hole in the ear, and a clutch which fits over the opposite end of the pin and rests against the opposite side of the ear to hold the earring therein. The clutch includes a spring for receiving the pin therein and having a reduced inside diameter intermediate turn thereof which is stretched by the pin as it passes therethrough. There is at least one circumferential receiving groove in the pin to receive and hold the reduced inside diameter spring turn. Thus, the clutch may be positioned so that the reduced inside diameter turn is received in one of the at least one grooves. This resists movement of the clutch along the pin. With multiple grooves the grooves are positioned along the pin so that for each groove, the earring comfortably fits a different size ear.

Abstract: A transformer or inductor bobbin (2) having pins (24) of a rectangular cross-section with complementarily profiled ends (24A, 24B), of which one (24A) is tapered and the other (24B) has a recess (24E). The rectangular cross-section allows the pins to offer greater resistance to bending in the direction of their cross-section's greater dimension (for pulling winding wire from the pins), while offering easier bending in the direction of their cross-section's greater dimension (for clinching to a printed circuit board). The use of pins having complementary profiles at their opposite ends allows the pins to be separated simply and efficiently from a length of material with no material wastage, and the provision of a taper at one end of a pin and a recess at the other end allows easy insertion of the tapered end into a pre-formed printed circuit board hole while the recessed end provides for collection of scraped material during pin insertion into an undersized hole (22) in the bobbin.
