Abstract: A method for pumping fluid at a wellhead. The invented method will improve liquid removal by eliminating the need to transport liquid produced from a well to containment facilities using trucks or large diameter pipelines capable of accommodating periodic surges of a high volume of fluid. The danger that the liquid will freeze in cold weather is also addressed. The invention removes liquid from the well site through a small diameter pipeline as a continuous flow at a constant flow rate.

Abstract: A substantially purified intra-acrosomal primate sperm antigen useful in a contraceptive vaccine is disclosed herein. The antigen remains associated with primate sperm after the acrosome reaction. In particular, it remains associated with the inner and outer acrosomal membranes. Modified antigens and fragments thereof prepared by protein modification techniques are also disclosed as well as methods for purifying and using the antigens. Also disclosed are monoclonal and polyclonal antibodies to the antigen and methods of making and using such antibodies. Methods of use include purification of the antigen or use in various diagnostic techniques. Also disclosed are cDNA, expression vectors, and transformed microorganisms that produce the antigen.

Abstract: A kit and method for detecting sperm production in a human male individual includes the provision of one or more antibodies for sperm tissue-specific protein antigen, such as SP-10, which can be combined with a sample suspected of containing sperm to permit the antibody and the antigen to bind. The binding event is determined directly or indirectly, which is indicative of the presence of sperm in the sample. The frequency of binding can also be determined by calibrating the means used to determine the binding event, so as to indicate sperm production at or above a given concentration. A variety of applications for the kit and method are described.

Abstract: The present invention provides a loudspeaker stand having a cup-shaped pedestal that may be perforated to provide an openwork below the loudspeaker to allow sound to be transmitted freely from the bottom wall of the loudspeaker, a tripod to support the pedestal and a brace assembly connected to the pedestal which includes a supporting post and tubes which extend vertically behind the back wall of the speaker to support a hub above the loudspeaker with arms projecting radially from the hub. Each arm has a corner socket connected to its free end to engage an upper corner of the loudspeaker to thereby brace the loudspeaker securely in place upon the pedestal.
