Title: Variable rate signal transmission in a spread spectrum communication system using coset coding
Inventor: ZEHAVI EPHRAIM
IPC: H04B1/707
Filed: 1994-11-01
Granted: 1997-06-05
Abstract: An improved system and method for communicating information at variable data rates over in-phase (I) and quadrature phase (Q) communication channels in a CDMA spread spectrum communication system is disclosed herein. In an exemplary implementation an input information signal is transmitted over either an I or Q communication channel using a direct sequence spread spectrum communication signal. The information signal is initially divided into first and second subsignals, which are respectively provided to first and second coset-encoding networks. The first coset-encoding combines the first subsignal with a first coset code, while the second coset-encoding network combines the second subsignal with a second coset code orthogonal to the first coset code. In this way the first and second coset-encoding networks are operative to produce first and second coset-encoded signals, respectively. A composite coset-encoded signal formed from the first and second coset-encoded signals is then modulated by an orthogonal function signal to provide a first modulated signal. In-phase pseudorandom noise (PNI) and quadrature phase pseudorandom noise (PNQ) signals of predetermined PN codes are used for spreading the first modulated signal for transmission to a receiver over either the I or Q communication channel, respectively. The receiver is operative to produce an estimate of the input information signal on the basis of the modulated carrier signal received over either the I or Q communication channel.

Title: Method of producing a metal section
Inventor: NIEMEIER RALF
IPC: B23P11/00
Filed: 1996-12-04
Granted: 2000-06-15
Abstract: A method of producing metal sections wherein first a groove is made in a section limb by microstructure-changing deformation, then another section limb is placed in the groove and that material of the first section limb which is situated to the side of the groove is moved onto the side walls of the inserted section limb by pressure to such an extent that an at least force-fitting joint between the two section limbs is made at the contact location. This method of microstructure-changing attachment of section limbs makes it possible to produce metal sections with virtually any desired geometry and using any desired starting materials the strength of which sections is comparable to metal sections produced in a previously known manner.

Title: Injector/valve combination designed to improve color dosing response time
Inventor: RAGSDALE MARK E
IPC: B29B7/60
Filed: 2000-02-23
Granted: 2003-02-06
Abstract: This invention relates to an improved injector/valve combination which permits nearly immediate response time to an actuator signal. Such a combination is particularly suited for injecting colorants into polyurethane slabstock foam and permits a substantial reduction in foam waste due to low colorations during an on/off cycle. Specifically, this invention combination comprises a novel ball valve (43) which allows for instantaneous shut-off and -on without appreciable leakage or pressure drop and without the need to utilize a high throughput flow rate. Such a ball valve (43) is used in combination with an injector (66) which is actually attached to the valve, the configuration which permits continuous use and instantaneous on/off without a deleterious pressure drop and minimizes the possibility of turbulence as the liquid polymeric colorant flows through the injector. The ball valve (43), the attached injector (66) configuration, the coloring apparatus comprising the inventive ball valve and/or the attached injector configuration, and the slabstock foam colored through the utilization of such an apparatus are also contemplated within this invention. <IMAGE>

Title: Process for preparing ketone enantiomer
Inventor: QUALLICH GEORGE J
IPC: C07C67/31

Abstract: A novel multi-step process for preparing the (4S &cir& _-enantiomer of 4-(3,4-dichlorophenyl)-3,4-dihydro-1(2H)-naphthalenone in a highly-optically pure form is disclosed. The process involves (1) first esterifying 4-(3,4-dichlorophenyl)-4-ketobutanoic acid with isopropylene or isobutylene to form the corresponding isopropyl or t &cir& _e &cir& _r &cir& _t &cir& _.-butyl 4-(3,4-dichlorophenyl)-4-ketobutanoate; (2) then reducing the ketobutanoic acid ester obtained in the first step with an asymmetric carbonyl reducing agent to form the corresponding chiral isopropyl or t &cir& _e &cir& _r &cir& _t &cir& _.-butyl 4-(3,4-dichlorophenyl)-(4R &cir& _)-hydroxybutanoate; (3) then sulfonylating the (4R &cir& _)-hydroxybutanoic acid ester with methanesulfonyl, benzenesulfonyl or p &cir& _-toluenesulfonyl chloride or bromide in the presence of a standard base to yield the corresponding isopropyl or t &cir& _e &cir& _r &cir& _t &cir& _.-butyl 4-(3,4-dichlorophenyl)-(4R &cir& _)-sulfonyloxybutanoate; (4) next subjecting the 4-sulfonyloxybutanoic acid ester obtained in the third step to a copper-coupling reaction with dilithium diphenyl(cyano)cuprate of the formula  PHI 2Cu(CN)Li2 to effect a stereochemical displacement of the organic (4R &cir& _)-sulfonyloxy group of the (4R &cir& _)-sulfonyloxybutanoic acid ester by the phenyl group of the dilithium diphenylcuprate reagent and so selectively form the corresponding isopropyl or t &cir& _e &cir& _r &cir& _t &cir& _.-butyl 4-(3,4-dichlorophenyl)-(4R &cir& _)-phenylbutanoate, and (5) thereafter cyclizing the stereospecific (4R &cir& _)-phenylated n-butanoic acid ester in the presence of a protic or Lewis acid catalyst to finally yield the desired (4S &cir& _)-4-(3,4-dichlorophenyl)-3,4-dihydro-1(2H)-naphthalenone compound in a highly-optically pure form. The latter compound, which is a novel (4S &cir& _)-enantiomer per se, has utility as an intermediate that ultimately leads to pure c &cir& _i &cir& _s &cir& _-(1S &cir& _)(4S &cir& _)N-methyl-4-(3,4-dichlorophenyl)-1,2,3,4-tetrahydro-1-naphthaleneamine (sertraline), which is a known antidepressant agent. The aforementioned isopropyl and t &cir& _e &cir& _r &cir& _t &cir& _.-butyl esters of 4-(3,4-dichlorophenyl)-(4R &cir& _)-hydroxybutanoic acid, as well as their corresponding (4R &cir& _)-methanesulfonyl, (4R &cir& _)-benzenesulfonyl and (4R &cir& _)-p &cir& _-toluenesulfonyl derivatives, are also novel compounds, as are the aforementioned isopropyl and t &cir& _e &cir& _r &cir& _t &cir& _.-butyl esters of 4-(3,4-dichlorophenyl)-(4R &cir& _)-phenylbutanoic acid as well as the aforesaid acid per se. These novel chiral compounds are all useful as key intermediates in the overall process of the present invention.
