Abstract: A new and distinct variety of nectarine tree denominated varietally as "Olympia" which is somewhat similar to the Red Jim Nectarine Tree (U.S. Plant Pat. No. 4,518) with which it is most closely related, but which is distinguished therefrom, and characterized as to novelty by producing fruit which is mature for commercial harvest approximately September 2 through September 23 at Fresno, Calif.; and which has fruit that has a bright red and glabrous skin; a firm flesh; and noteworthy storage characteristics.

Abstract: A new variety of African violets that have been bred from a hybrid formed by crossing Saintpaulia ionantha, the traditional florists' African violet with the high altitude species, Saintpaulia schumensis. The high cost of energy in northern latitudes and the relatively high temperatures required by Saintpaulia ionantha, which grows naturally at the foot of Mount Usamabara in East Africa, have made commercial growing of the violet expensive. By bringing in genes from Saintpaulia schumensis which grows at some 7,000 feet on the same mountain, where temperatures can fall as low as 55 degrees Fahrenheit, a new avenue of growth is opened up for this popular plant.

Abstract: An improved toothbrush having a handle and two sets of bristles; one set of bristles being disposed on each end of the handle. One set of bristles is configured as a conventional toothbrush and may, thus, have any one of a number of combinations of bristles and shapes for performing routine dental hygiene. The other end of the brush is unique in both the configuration of the supporting portion of the handle, the crescent configuration of the bristles and the articulation (pivoting action) of the crescent-shaped toothbrush relative to the handle. This portion of the handle is further modified (curved) to support the crescent-shaped bristle as to place them in opposing relationship to the inside surface of the user's teeth. This is achieved without any strain or unorthodox positioning of the brush by the user. Since the crescent-shaped toothbrush is able to articulate (pivot) relative to the handle, it is equally effective in cleansing all inside surfaces of the teeth, not simply the front teeth.

Abstract: In a door closer, there are provided a vertical rotatable shaft associated with the rotation of a door through an arm, two cams installed integral with the shaft, an urging device for rotating the door in the closing direction through one of the cams and a cylinder device for braking the door during door closing operation through the other of the cams. Thus, the opening of the door is effected by overcoming the force of the urging device and hence the door can be opened lightly. When the door is released, the force of the urging device is transmitted to the one cam and then to the arm, so that the door can be automatically closed. During door closing operation, the cam surface of the other cam pushes the piston rod of the cylinder device, whereby the rotation of the other cam and hence the rotation of the shaft connected with the other cam are braked, avoiding severe shocks to the door.

Abstract: A door closer is described in which transmission ratios which change in dependence on the closing angle can be realized by eccentric toothed elements. The toothed elements can have different profile offsets, moduli and flank angles along their respective pitch curves.

Abstract: A fish scaling apparatus includes a container having a bottom and an upstanding side wall, and a cylindrical insert including a plurality of inwardly-extending projections. The projections in the insert into the interior of the insert, and are provided with a rough or sharp edge. A paddle member is disposed within the interior of the cylindrical insert, and is connected to a shaft extending exteriorly of the container. The shaft is adapted for connection to the chuck of a portable drill. When the drill is operated, rotation of the paddle member is caused within the interior of the cylindrical insert. Such rotation causes fish disposed within the interior of the cylindrical insert to come into contact with the inwardly-extending projections disposed on the side wall of the cylindrical insert, for removing the scales from fish. The paddle member may also be provided with a series of spaced projections for aiding in the removal of scales from the fish during agitation.

Its elements consist of a board, a supporting base, a clamping element, a torsional spring and a pivotal axle. The distinctive features are that the supporting base is made of metal plate with both sides bent upward and ends rolled up into tube shape. On the board, two transverse groove slots are provided to allow the tube-shaped element of supporting base penetrating through upward from the bottom of the board for combination with clamping element, spring and pivotal axle into an integral clipboard.

Abstract: A one piece plastic clamp has a generally U-shaped outer structure including two outside legs and a thinned and downwardly curved upper bridging region from which the legs integrally depend. The clamp further includes a live hinge toggle joint for spanning the upper outside ends of the legs. The toggle joint has a release position peaking freely above the upper bridging region as the legs move relatively together and apart in the release position, and has a stable snap lock position directly adjacent to the upper bridging region thereby forcing the outer legs together in a clamped position. Two oppositely facing inner clamping jaws are relatively moveable freely with respect to each other and with respect to the outer structure in the release position. The jaws are for clamping an article between opposite faces when the clamp is in its snap lock position.

Abstract: A tool and a method for loading pins into pin holes in the bore of the cylinder of a tumbler lock is disclosed. The tool is an elongated rod with two rod sections, a loading section and a handle section having a greater circumference than the rod section to form a shoulder. A contiguous groove runs lengthwise through both rod sections and includes perpendicular pin holes in the loading section. A tapered blade is provided to slide in the groove. In use, the pins are loaded into predetermined pin holes in the loading section. The loading section is inserted into the cylinder bore until the shoulder of the handle section prevents further forward motion and aligns the rod pin holes with matching pin holes in the cylinder. The blade is pushed towards the cylinder and urges the pins from the rod holes into the cylinder pin holes. With the blade holding the pins in the cylinder pin holes, the rod is turned so that the pins are now held in place by the rod itself.

Abstract: A method for preventing corrosion of an expandable mounting element which involves introducing a sealing composition into a mounting hole of a support structure first to fill the hole about half-way, then driving an expandable mounting element into the half-filled hole to displace the sealing composition initially against the base of the mounting hole and then up along the surface of the expandable mounting element until the excess emerges out of the mounting hole. A compressible impact device, which has an upper and lower part and a spring part fixed therebetween, is arranged so that an impact tool can be driven against the upper part to fully drive the expandable mounting element into the mounting hole, effecting a sealing compaction in correspondance with the pressure exerted by the spring part. All gaps and cracks are thereby sealed against corrosive media.

Abstract: A method and apparatus for bonding two articles and in particular a metal trim strip to a thermoplastic article such as is used for automotive decorative window trim. The thermoplastic article includes a raised ridge portion which serves to provide means for accurately aligning the metal trim strip on the thermoplastic article. A plurality of holes are formed through the ridge portion at spaced locations along its length. The metal trim strip is preferably "C-shaped" in cross-section so as to define a channel having a restricted opening for receiving the raised ridge portion of the thermoplastic article. A controlled flow of hot air is directed into the holes of the thermoplastic article to plasticize a controlled portion of the thermoplastic material surrounding the holes. A stake is then projected into the plasticized material to displace the plasticized material into the channel portions of the metal strip.

Abstract: The invention provides a method of manufacturing a hollow metal light conductor in which at least one metal layer is provided on a core of a synthetic resin material, for example, polymethylmethacrylate, after which the core is removed, and a metal tube is formed.
