Inventor: TABAK SAMUEL ALLEN
IPC: C07C41/06
Filed: 1987-07-16
Abstract: A multistage process for producing isoalkyl ethers from lower aliphatic oxygenate feedstock, such as methanol. Feedstock is catalytically converted in a primary catalyst stage at elevated temperature in contact with zeolite catalyst to predominantly C2-C7, for example C2-C5, lower olefins comprising isobutylene and isoamylene, by-product water and a minor amount of C8<+>, for example C6<+>, hydrocarbons, followed by fractionation of the C2-C7, for example C2-C5, olefins to recover a C2-C3-rich recycle stream for further catalytic conversion in the primary stage. C4-C7, for example C4-C5, olefins are passed to a second catalytic etherification stage for reaction of isoalkenes with methanol to produce methyl tertiary-butyl ether, methyl isoamylether and higher isoalkyl ethers. The second stage effluent may be fractionated to recover an ether product, C5<+> hydrocarbon liquid product, and unreacted butenes. Advantageously, the unreacted butenes are further reacted with isoparaffin in a third catalytic stage under acid catalysis alkylation conditions, and fractionated to recover C6<+> alkylate liquid, liquid hydrocarbon product. The ethers may be blended with at least one C6<+> hydrocarbon to produce high octane gasoline.

Title: Digital overspeed controller for use in a vital processing system
Inventor: RUTHERFORD DAVID B
IPC: B60L15/20
Filed: 1989-10-20
Granted: 1999-07-27
Abstract: The functions to be performed by a digital overspeed controller are implemented by application of two concepts, namely "diverse channels" and "even/odd systems cycles"; in accordance with the ~irst concept; two channels are maintained throughout the overspeed controller, beginning with two independent tachometer inputs; all of the functions involve operations to be performed in each of the two channels separately.   The numerical results for each of the channels are different and the numerical difference between the two channels is used to prove the integrity of the functions described.  The second concept of "even/odd system cycles" involves a "system cycle time", denoted T CYC, that is nominally 100 milliseconds.   All of the functions of the controller are performed each system cycles.  In order to be able to vitally distinguish data results between adjacent cycleq, the cycles are denoted EVEN and ODD, and the results of each of the operations produce different numerical values on even and odd cycles.

Title: Ultrasonic terrain or ground or soil distance measuring system for vehicles or agricultural implements
Inventor: HAWKINSON JEFFREY CONRAD
IPC: A01B63/111
Filed: 1991-04-25
Granted: 1997-10-07
Abstract: A  distance  sensing  system  includes  an  ultrasonic transducer,  a transceiver and a microcontroller-based signal processing unit.  The  transducer periodically  generates  and directs towards the terrain a dual frequency ultrasonic signal. Echo signals from the ground and/or any intervening crop or trash are reflected back to the transducer and are processed.   The system generates amplified and filtered echo envelope signals. Leading and trailing edge times are determined as the times the echo  signals  cross  a  threshold  value  which  is  a  certain proportion of a maximum echo amplitude value.  A near distance value is derived from the leading edge time of the first echo which exceeds a minimum amplitude.   A far distance value is determined as the trailing edge time of the last echo signal which has an amplitude which exceeds a certain value.  Multiple echo time and amplitude values are derived from the maximum amplitude echo.  These values are used to prevent echoes which occur after the multiple echo time with less than a certain amplitude from being used  in the determination of the far distance value.  This far distance value represents the distance to ground and weaker, earlier echoes from trash or crop and later, multiple echoes may be ignored.

Inventor: VAUGHAN JOAN
IPC: C12N15/16
Filed: 1990-03-20
Granted: 2000-08-22
Abstract: Mammalian melanin-concentrating hormone (MCH) is isolated from rat tissue, purified and characterized. These MCH peptides are useful for treating skin disorders, for suppressing the proliferation of skin tumor cells, such as melanomas in mammals, and for modulating the secretion of ACTH. Generally, peptides are provided which have formula (I), or which are naturally occuring homologs of the peptide with said formula. The peptides which are the naturally occurring MCH homologs of mammalian species other than rat can also be obtained using the materials disclosed, as demonstrated specifically with human MCH, which is found to have the same structure as rat MCH. Also disclosed are the amino acid sequences of, and the nucleotide sequences of the cDNAs which encode, the putative precursors of rat MCH and human MCH. These precursors may also include one or more biologically active peptides N-terminally of the mature MCH's. Among these peptides, which are thought to be formed from the MCH precursors, are the peptides with the sequence H-Glu-Ile-Gly-Asp-Glu-Glu-Asn-Ser-Ala-Lys-Phe-Pro-Ile-NH2, which is cross-reactive with antibodies against alpha-MSH and CRF, and the peptides with the sequence H-Gly-X NGE-Phe-Pro-Ala-Glu-Asn-Gly-Val-Gln-Asn-Thr-Glu-Ser-Thr-Gln-Glu-OH, wherein X NGE is Pro-Ala-Val or Ser-Val-Ala, which is cross-reactive with antibodies against GRF.
