Abstract: The present invention is a key ring splitter for separating an end of a conventional key ring so as to locate keys thereon or also remove keys. The present invention utilizes a pulling motion to separate the key ring instead of a pushing motion and also includes a self-alignment feature. The key ring splitter includes a front section with a front end and a rear section with a rear end. The front section is provided with a small rectangular shaped opening which is defined by an upper edge, a lower edge, a proximal edge adjacent to the front end, and an opposite distal edge.

Abstract: Nucleic acid molecules are provided which encode antigenic proteins capable of inducing in a chicken an immune response conferring protection against Eimeria tenella. Expression vectors containing the nucleic acid molecules are also provided. Methods for producing the proteins or antigenic polypeptides having amino acid sequences included within these proteins are also provided.

Abstract: An electrical connector system is provided, of the type that includes housings of plastic-metal hybrid construction, which provides good moisture-tight sealing between the plastic shells and metal inserts and around grounding springs. The receptacle connector has a front edge to which the plastic shell and metal insert extend, and the plug connector includes a ring-shaped elastomeric first seal (90, FIG. 3) that is compressed by the front edge of the receptacle shell and insert (96, 98), to not only seal the inside of the mating regions of the connector but also to seal any slight gap (100) between the plastic shell and metal insert of the receptacle. The forward edge of the plug presses against a second elastomeric seal (92) which is on the receptacle, with the first and second seals sealing a region containing a grounding spring (80) that electrically connects the inserts of the plug and receptacle.

Abstract: A purified antigenic protein has been obtained which is capable of inducing in a chicken an immune response conferring protection against infection by Eimeria necatrix or Eimeria tenella. The protein has a molecular weight of about 26,000 and is composed of two polypeptides joined by a disulfide bond. The two polypeptide subunits have molecular weights of about 18,000 and about 8,000, respectively. The gene encoding the protein has been sequenced and the amino acid sequence of the protein deduced therefrom.The protein and antigenic polypeptides having an amino acid sequence included within the protein may be incorporated into a vaccine for conferring upon a chicken active immunity against infection by E. necatrix or E. tenella.

Abstract: A genomic DNA molecule having the nucleic acid sequence set forth in FIG. 1 and encoding an antigenic protein derived from Eimeria tenella has been isolated. The protein has a molecular weight of about 25,000 daltons and is composed of two polypeptides joined by a disulfide bond. One of the polypeptides is characterized by a molecular weight of about 17,000 daltons and by a blocked N-terminal amino acid and having the amino acid sequence set forth in FIG. 1. The other polypeptide is characterized by a molecular weight of about 8,000 daltons and has the amino acid sequence set forth in FIG. 1.A cDNA molecule encoding the 25,000 dalton polypeptide with a continuous amino acid sequence has been inserted into expression vectors capable of expressing the 25,000 dalton polypeptide directly or as a fused polypeptide. The polypeptides produced are used in vaccines to immunize chickens against infection by Eimeria tenella.

Abstract: A pair of U-shaped dentition trays are joined by a bendable bridging member that is reinforced by molded portions that function to maintain the trays biased apart and in tooth contact in a person's mouth.

Abstract: A continuous business form for use in automated mailing systems including a single elongated ply having control punch margins on its longitudinal edges. Longitudinal lines of weakening are disposed inwardly of the control punch margins to define removable feed strips and a main panel. The main panel is divided by a plurality of cross lines of weakening into a mailing facilitating panel and a message bearing panel such that the mailing facilitating panel has a length that is a minor fraction of the length of the message bearing panel. Mailing facilitating devices, such as an envelope, a label, or a stencil, are carried by the mailing facilitating panel.

Abstract: A pair of arcuate concavo-convex trays formed of a plastic foam material shaped to be inserted into the mouth and to encase both the upper and lower jaws. The trays are normally disposed in mirror-like opposition and joined anterior-to-anterior by a bridge member adapted to bow, bend or fold so that the exterior surfaces of the trays are juxtaposed bottom to bottom. The trays are used to receive and contain a medicament for topical application to a person's teeth, fluoride gel being a typical topical material.

Abstract: An electrical connector having a split bolt and a cap. The slot in the bolt extends axially into the bolt to a point displaced from a lateral flange. When a wire is passed through the slot, the cap is threaded onto the bolt deflecting the wire into a non-linear path and clamping it in at least two places.

Abstract: A rail joint includes an insulative base piece insertable between a rail base flange and a joint bar. The ends of the base piece project longitudinally beyond the respective ends of the joint bar to provide exposed terminal sections with an intermediate central section. Longitudinal migration of the base piece during travel over the rail joint is precluded by one or more end abutment members fixedly disposed relative the base piece and including an elevated inner abutment surface intermediate the central section and each terminal section and engaging the joint bar ends. The abutment members may comprise integral elevated tabs cut from the base piece or alternatively, separate members insertable through cut-out portions in the base piece terminal sections.

Abstract: A multi-dial, manually operable indicator employing color-coded, alphabetical and numerical indicia which are indicative of railway or road vehicle destinations, regardless of whether they may be local or outbound, major or minor vehicle defects requiring repair, other varied information requiring matching of indicia for proper vehicle selection, and other indicia affording useful information to the driver of the associated vehicle or highway or railway personnel. A novel clutch mechanism which is effective under the control of a single knob affords selective dial rotation while other manually operable knobs effect pointer operations indicative of the condition of special vehicle equipment such as refrigeration apparatus or the like.
