Abstract: Case 2973 IMPROVED WHEEL SLIP CONTROL USING DIFFERENTIAL SIGNAL             ABSTRACT OF THE DISCLOSURE Apparatus for controlling wheel slip in a diesel electric locomotive has sensors which determine wheel speeds for each driven wheel and a circuit which selects the fastest turning wheel and the slowest turning wheel and provides signals representing these and also a circuit which provides signals representing the greatest and smallest acceleration rates for the fastest and slowest turning wheels.  When the difference in the fastest and slowest turning wheel speeds exceeds a reference determined by speed, then a creep signal is provided.  When the greatest acceleration exceeds a threshold determined by motor current and speed, the greatest acceleration rate is added to the smallest acceleration rate and a rate power reduction signal is provided.  A fast servo circuit receives an input representing desired power supplied to the motors and a signal representing actual power and provides a rapidly decreasing power control signal in response to an appreciable decrease in the actual power.  The creep signal, rate power reduction signal and the power control signal are summed to reduce the reference signal which controls the motors.

Abstract: PHASE ADJUSTMENT SYSTEM     Abstract Synchronization facilities are disclosed for maintaining error free timing of a digital system when control of the system timing is switched between a plurality of clock sources.  The signal of each source is applied to an associated counter divider whose output is applied to switch facilities which extend the output of only one divider at a time as a reference clock source to the digital system.  The dividers for the other sources are forcibly reset each time the divider of the reference source advances from its all is to its reset (all Os) position.  This maintains the output signals of all dividers in phase with each other to prevent disturbances to the digital system when its timing is switched between clock sources.

Date Jun. 14, 1990.The polysaccharide araban is extracted from sugar beet by a novel modification of the known alkaline extraction process in which, after neutralization of the alkaline liquor, the liquor is ultrafiltered and the retentate is dried to obtain dry araban. Araban, obtained by the above process or otherwise, is incubated with alpha -L-arabinofuranosidase to cleave most or all of the branches from the araban. The debranched araban forms an aqueous gel which has the properties of a fat mimetic and may be used as a fat substitute in foods. Isolated debranched araban derived from crude sugar beet araban is a novel substance. Araban itself may be used in the novel applications of emulsification and encapsulation of oils, for example flavor oils.

Abstract: The present invention is directed to genes, termed Rpt-1 (regulatory protein T lymphocyte-1), which are expressed at higher levels by resting CD4+ helper/inducer T cells relative to activated CD4+ cells. The invention also relates to the proteins encoded by such genes, termed rpt-1 proteins, which regulate gene expression directed by the promoter region of the interleukin-2 receptor (IL-2r) alpha chain gene or by the promoter region of the long terminal repeat of human lymphotropic retroviruses such as the human immunodeficiency virus type 1 (HIV-1) human T cell leukemia virus (HTLV)-I, and HTLV-II. In particular, rpt-1 proteins down-regulate gene expression controlled by the promoter of the IL-2r alpha chain gene or by the promoter of the long terminal repeat of HIV-1. The proteins and nucleic acids of the invention have value in diagnosis and therapy of immune disorders such as AIDS. In a specific example of the present invention, an Rpt-1 gene and its encoded intracellular protein of approximately 41,000 daltons molecular weight are described. The rpt-1 protein is shown to be selectively expressed by activated CD4+ T cells, and to down-regulate gene expression of the IL-2r and the HIV-1.
