Abstract:
The present invention provides compositions and method for the preparation of emulsions and multiple emulsions. Specifically, the invention provides solids which are self-emulsifying glasses which, on contact with a sufficient amount of an aqueous phase, form emulsions or multiple emulsions without input of emulsive mixing. Emulsions and multiple emulsions produced from the self-emulsifying glasses are encompassed by this invention. The self-emulsifying glasses are prepared from certain matrix compounds and an oleaginous material by a solvent method. The glass results from removal of solvent from a combination of matrix compound, oleaginous material and a solvent which dissolves substantially all of the matrix compound. Multiple emulsions result from glasses in which the oleaginous phase is a primary, e.g. water-in-oil emulsion. The glasses and emulsions produced therefrom are particularly useful pharmaceutical, food and cosmetic applications.
Abstract:
Disclosed herein is a synthetic senescent cell antigen comprised of purified peptides immunoreactive with antibodies to the naturally occurring antigen. Preferably, the synthetic senescent cell antigen comprises two peptides with the amino acid sequences SKLIKIFQDHPLQKTYN and LFKPPKYHPDVPYVKR, respectively.

Abstract:
A method of and apparatus for providing error correction coding for a block of user data is disclosed in which the user data (101) is initially modulated by a first modulator (102) and then the modulated user data (108) is error correction encoded to produce a first plurality of check bits (106). The first plurality of check bits are then modulated by a second modulator (114) whose output is then fed to a second error correction (120) which produces a second plurality of check bits (118). The modulated user data, the first plurality of check bits and the second plurality of check bits are all fed to a shift register (128) where the error correction encoded user data block is formed. The present invention is useful with magnetic and optical storage devices.
Abstract:
An explosive detection screening system (10) used for the detection of explosives and other controlled substances such as drugs or narcotics. The screening system detects the vapor and/or particulate emissions from the aforementioned substances and reports that they are present on an individual or object and the concentration of each substance detected. The screening system comprises a sampling chamber (20) for the collection of the vapor and/or particulate emissions, a concentration and analyzing system (45) for the purification of the collected vapor and/or particulate emissions and subsequent detailed chemical analysis of the emissions, and a control and data processing system (50) for the control of the overall system.
