A probe is provided for collecting mucous tissue samples in vivo particularly from the conjunctiva, the urethra and the cervix. The probe comprises a handle portion and a body portion, which is slotted for scraping tissue into the slots. The tissue sample may then be introduced into an aqueous transport medium comprising sucrose, potassium phosphates, foetal bovine serum, streptomycin, vancomycin and nystatin. The sample may be smeared from the transport medium, with the cells still intact onto ...

An electrographic imaging member comprising a supporting substrate and an outer layer of a volume grafted fluoroelastomer comprised of a substantially uniform integral interpenetrating or crosslinked network of a polyorganosiloxane grafted fluoroelastomer.

The present invention is directed to anticoccidial methods, animal feed premixes, and animal feeds, employing a specified o-phenylenediamine or benzimidazole. The present invention is also directed to anticoccidial methods, animal feed premixes, and animal feeds employing two active agents. In such combined therapy, a first substance is a polyether antibiotic, and the second substance is a designated o-phenylenediamine, benzimidazole, or benzimidazoline.

Methods for lifting equipment such as utility vehicles (e.g., three-wheeled commercial mowers, four-wheeled vehicles, outdoor power equipment, etc.) for inspection, servicing and repair purposes are disclosed. The lifting methods use apparatus which includes spaced-apart tool bars and wheel lift means carried by the tool bars. The wheel lift means are movable along the tool bars and preferably are also movable transversely of the tool bars and are able to engage the wheels of the vehicle even wh...

Tools for setting precious and semi-precious stones in metal, and methods for using such tools to set such stones quickly and to accomplish such setting in the absence of chisel marks in the finished products. A first tool includes a disc-shaped rotating grinding member that has a beveled cutting edge for trimming excess metal prior to making the setting. A second tool has a disc-shaped rotatable cutting member having a kerfed cutting edge that produces parallel channels in such metal to thereby...

The present invention provides methods of sealing subterranean zones using high density sealing compositions. The methods are basically comprised of introducing a sealing composition into the subterranean zone comprised of a high density aqueous salt solution, a polymerizable monomer and a polymerizable initiator and allowing said sealing composition to form a sealing gel in said zone.

New radiopharmaceutical compositions for use in nuclear medicine comprise radioastatinated benzylguanidine and radioastatinated carboxamidino phenylpiperazine. These compositions are used for treatment of disease, including neuroendocrine tumors, and specifically neuroblastoma.

A method of joining two fabric surfaces together which comprises: sewing a synthetic, fusible, thermoplastic thread to one of the fabric surfaces to be joined, the sewing taking the form of a blind sewing stitch which passes through only a portion of the full depth of the fabric and which interloops with itself or with one or more other threads on the surface of the fabric; bringing the surface of the fabric containing the interlooped thread stitch into contact with the other fabric surface to b...

A method of making an incandescent lamp comprises passing a filament for the lamp and a filament support through an opening in a bulb so that conductors from the filament pass out through the opening. An exhaust tube is then placed partially inside the bulb through the opening with the conductors passing between the tube and the edge of the wall of the bulb surrounding the opening. The exhaust tube is then sealed to the bulb and the interior of the bulb subjected to a vacuum. The exhaust tube is...
