Title: Higher modulus compositions incorporating particulate rubber
Inventor: MCINNIS EDWIN L
IPC: C08F8/00
Filed: 1993-02-22
Abstract: Rubber particles, to be used as fillers or extenders for various composite polymer systems, are chlorinated by a gas-solid phase reaction with a chlorine-containing gas. A composite polymer containing the chlorinated rubber fillers or extenders exhibits a higher flexural modulus than if prepared using an unchlorinated rubber filler or extender. Chlorination of the rubber particles is carried out by contacting the finely divided rubber particles with a chlorine-containing gas comprising at least about 5 volume percent chlorine.      Advantageously, the chlorine can be diluted with air, nitrogen or other essentially inert gases and may contain minor amounts of fluorine.      Improved performance is obtained with nitrogen dilution of the chlorine gas over air dilution. Improved polymer composite systems having higher flexural modulus result from the use of the chlorinated rubber particles as fillers instead of unchlorinated rubber particles.

Abstract: ABSTRACT OF THE DISCLOSURE A support bar for a storage rack includes a first downwardly facing u-shaped channel forming two sidewalls each having a lower edge at the open side of the channel.          A second upwardly facing u-shaped channel faces the opposite direction of the first channel, and is formed as an extension of the lower edge of one of the sidewalls so that the two channels form an s-shape.  A low friction material is disposed in the second channel, the material having a channel formed therein.  A flange is formed as an extension of the lower edge of the other of the sidewalls, the flange extending upwardly away from the lower edge.          The flange provides an edge to hang tape reels from, and the multipacks can be mounted in the rack by placing a first one of their flanges in the channel formed in low friction material, with the other flange resting inside the downwardly facing channel with the multipack in a tipped-back position, the channel of the low friction material allowing the multipacks to be slid freely back and forth along the length of the bars.

Title: Methods for the use of spermidine/spermine n1-acetyltransferase as a prognostic indicator and/or tumor response marker
Inventor: PORTER CARL W
IPC: A61K31/13
Filed: 1993-04-19
Abstract: Abstract Disclosed is a method that relates to the measurement of determinants related to the in-vivo induction of spermidine/ spermine Nl-acetyltransferase (SSAT), subsequent to treatment with polyamine analogs that induce SSAT such as bis-ethyl spermine analogs, in tumor types responsive to this class of analogs. The method comprises the measurement of one or more SSAT-specific determinants  that  include  SSAT enzyme  activity,  SSAT  enzyme protein,  and  SSAT  m-RNA  transcripts.  Alternatively,  other determinants related to the SSAT induction may be measured. Such determinants include SSAT co-factor acetylCoenzyme A,  and SSAT products Nl-acetylspermidineand Nl-acetylspermine. Measurements of these determinants may be useful as prognostic indicia and tumor response  markers  to  evaluate  the  clinical  effectiveness  of anticancer agents comprising polyamine analogs, such as bis-ethyl spermine analogs, that induce SSAT activity.

Filed: 1993-06-15
Abstract: A spinning strip aperture imaging radiometer sensor system and data processing method that is capable of synthesizing full circular aperture images from a plurality of image frames acquired by the strip aperture imaging sensor. One embodiment of the imaging system comprises a rotating strip aperture wide field of view telescope, a two dimensional detector array used to detect images in the telescope's focal plane, a rotation compensation device used to prevent rotational smear during the integration time of the detectors, a signal processor used to record a plurality of image frames of a target scene that is imaged by the telescope as it rotates around its optical axis, and a signal processor and method used to synthesize the full circular aperture image from the recorded images. The operation of the full aperture image synthesis method hinges upon the ability of the rotating strip aperture to measure all of the spatial frequencies contained in a full circular aperture image measurement. Having knowledge of the strip apertures' spatial frequency passband, and the temporal registrations of each of the recorded strip aperture images permits synthesis of the full aperture image by the sensor system and image synthesis method. Image synthesis may be accomplished in the spatial or spatial frequency domains. General and illustrative examples of the image synthesis procedure and first order noise performance predictions are described. A general form of the invention utilizes two dimensional spatial frequency information to greatly reduce the line of sight stability requirements of the telescope.
