Title: Chemical preparation of high specific activity nucleotide probes
Inventor: BAHL CHANDER
IPC: C12Q1/68
Filed: 1989-12-14
Abstract: The preparation includes providing a first target recognition moiety comprising a nucleotide sequence of at least about 15 nucleotide bases, the sequence containing at least one 5' end and 3' end, chemically altering the first target recognition moiety to contain a reactive functionality at the 5' end, the 3' end, or both, and providing a second signal generating moiety, having at least one terminus containing a functionality that is capable of reacting with at least one reactive functionality provided on the first target recognition moiety, and chemically reacting the first target recognition moiety now containing reactive func-tionality, with the terminus of the second signal generating moiety, to chemically join these two moieties and produce the labeled nucleotide probe. This method provides an interesting alternative to the syntheses of labeled nucleic acid probes known to the art.  It also provides diagnostic and research reagents containing the probes.

IPC: F16C19/06
Filed: 1990-09-24
Abstract: ABSTRACT OF THE DISCLOSURE      A support for rotatably supporting a portion of a shaft, specifically a drive shaft of a vehicle, is disclosed. An intermediate drive shaft support is required when three or more universal joints are embodied in a drive line between a trans-mission and a differential of the vehicle. An intermediate drive shaft is sufficiently long that it tends to bend or whip to an objectionable extent. The shaft support features a simplified, lower-cost bearing having fewer rolling elements in the form of balls or rollers between inner and outer races, there being from three to six and preferably four. Two rings are located on the sides of the rolling elements to uniformly circumferentially space the elements and can also provide lubricant seals. Each of the rings has a plurality of uniformly circumferentially spaced recesses in which portions of the rolling elements are received. Each of the rings can have annular sealing lips which engage the inner and outer races and can also have an annular ridge which engages a flinger located adjacent the inner race; to hold the ring in place. The races, rolling elements, and spacing and sealing rings can be made of lower cost materials which are also easier to manufacture.

Abstract: The amount of ionizable substance within a stream can be continuously monitored through the use of an ionizable substance detector.  The substance is ionized at an electrode producing ions and free electrons.  The ions are transported across an ion exchange membrane, while the free electrons flow through a power source.  The current, produced by the electrons, is proportional to the amount of substance in the stream.  Continuous monitoring can be useful in early detection of problems, or system fluctuations.
