Abstract: 1,170,107. Amides or salts of vinyl ether/ polybasic acid copolymers. MONSANTO CO. 3 Feb., 1967 [4 Feb., 1966], No. 5337/67. Heading C3P. [Also in Division D2] Sizing agents for fibrous materials comprise a partial amide, mono- or di-ammonium salt, amide-amine salt or alkali metal salt of a copolymer of (a) vinyl ethers with 8-25 carbon atoms in the non-vinyl portion, and (b) residues of unsaturated polybasic acids, in an ether-toacid residue molar ratio of between 1/0À9 and 1/1À8, preferably with the ether and acid residues alternately disposed. Other monomers may be present such as di-isobutylene, vinyl-toluene, styrene, acrylonitrile and methyl methacrylate. Various alkyl, alkenyl, aryl, alkylaryl, alkoxyaryl and aryloxyalkyl vinyl ethers are specified. The polybasic acid residue may be introduced by means of a C 4 -C 10  acid anhydride, e.g. maleic, itaconic, aconitic, citraconic or chloromaleic, or by using monomethyl maleate, fumaric acid or hexen-3-ylene-1:6-dicarboxylic acid. Up to 10% of olefinic monocarboxylic acid may also be present, e.g. acrylic or crotonic. Polymerization is effected in benzene, toluene or xylene, with catalysts such as azobis-isobutyronitrlie, di-tert-butyl peroxide, tert-butyl perbenzoate or benzoyl peroxide, and a 50-150‹ C. initiator such as isopropyl peroxydicarbonate or tetrachlorobenzoyl peroxide. An alkanol may also be present to convert the acid anhydride groups into partial esters. The products have a mol. wt. below 200,000. The polymers are converted into their amide and/or salt derivatives by treatment with ammonia, alkali metal hydroxide or an amine of mol. wt. below 300, e.g. methylamine, ethylamine, diethylamine, propanolamine, diethanolamine, triethylamine or tributylamine. Compositions are formed of the above polymer derivatives with starch or proteinaceous sizes, e.g. corn, potato, sago, wheat, enzymeconverted, hydroxyethylated or oxidized starches, cationic starches having quaternary ammonium or other amine salt groups, or starch derivatives such as British gums.

Title: Seat with a seat plate of adjustable inclination and a backrest of adjustable inclination
Inventor: MEILLER H
IPC: A47C1/024
Filed: 1980-06-27
Abstract: In a seat having a seat plate of adjustable inclination and a backrest of adjustable inclination, gas springs are provided for adjusting the inclination of the seat plate and backrest, the valve actuating pins of the gas springs being oppositely disposed and actuatable by an adjusting lever. The adjusting lever extends transversely to the valve actuating pin arrangement and is mounted to pivot vertically and horizontally about a common pivot point disposed beyond the straight connecting line between the valve actuating pins. In the preferred embodiment, two control arms on the seat carrier are movable in a scissor-like manner in a vertical plane containing the valve pin arrangement, the adjusting lever engaging between and co-operating with the control arms which co-operate with the valve actuating pins. This permits the inclination of the seat plate and the inclination of the backrest to be adjusted with a single operating element either at independent times or simultaneously.

Title: Bandwidth synthesis for wireless location system
Inventor: STILP LOUIS A
IPC: H04W4/90
Filed: 1999-12-13
Granted: 2003-03-12
Abstract: A wireless location system receives signals transmitted by wireless telephone at a plurality of signal collection sites (scs 10A, SCS 10B, SCS 10C). To improve the accuracy of the location information, the system synthesizes greater bandwidth, and thus greater time resolution, than would otherwise be available. The location system commands an MTSO to make the wireless transmitter to be located change frequency channels, and a doubly-differenced carrier phase of the transmitted signal, or the time difference of arrival, is observed at each of many frequencies spanning the widest possible bandwidth. The phase-measurement data from these many frequencies are combined to resolve the inherent integer-wavelength ambiguity. To begin the process of ambiguity resolution, single-frequency channel, doubly-differenced group delay measurements are used to resolve the ambiguity in the doubly-differenced phase difference between the most closely spaced frequency channels.
