Abstract: A polymeric salt comprises the calcium, aluminium or magnesium salt of a carboxyl group-containing water-swellable resin formed of monomeric units of one homo-polymerizable carboxylic acid having one or more ethylenic double bonds, or of two or more co-polymerizable carboxylic acids, each having one or more ethylenic double bonds, and cross-linked with from 0.01 to 2.0% by weight of a cross-linking agent, said salt being substantially free of other metallic cations. Acids specified include acrylic, methacrylic, fumaric, maleic, monomethyl maleic, itaconic acids and their salts. The cross-linking agent may be any polyunsaturated compound; exemplified are divinyl benzene, p-diisopropenyl benzene, 2,5-dimethyl - 3,4 - dihydroxy - 1,5 - hexadiene, 1,1,3,3 - tetraallyl - 1,3 - propanediol, 1,1,3,3-tetramethallyl - 1,3 - propanediol, 4,6 - dimethyl - 4,6 - dihydroxy - 1,8 - nonadiene, 2,3,6,8 - tetramethyl - 4,6 - dihydroxy - 1,8-nonadiene, 3,4 - dihydroxy - 1,5 - hexadiene, and 2,5 - dimethyl -1,5 - hexadiene.

Title: Microwave amplifier arrangement
IPC: H03F7/04
Filed: 1969-05-30
Abstract: 1,272,297. Parametric amplifiers. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 30 May, 1969 [1 June, 1968], No. 27612/69. Heading H3B. In a microwave amplifier, the output U 2  of a mixer chain amplifier including an up converter D 1  and a down converter D 2  is connected via a transformer  to the input U 3  of a similar mixer chain amplifier. The signal current Is flows into input admittance YE from a source of conductance G S , while the final output is from admittance Y A <SP>1</SP> into load conductance GL. The noise figure may be minimized by making GL equal to the real part of Y<SP>1</SP> A . By varying the ratio of the real part of Y E  to G S  it is possible to combine the minimum noise figure with input power matching, or to make either the first or second mixer chain amplifier have unity gain and act as an isolator. The reactance diodes D, D<SP>1</SP> are operated in phase quadrature at their resonant frequencies. Each stage may have a neutralizing inductor connected between its input and its output. The amplifier is stated to be suitable for television input stages.

The term "lower" indicates not more than 7 carbon atoms in the groups so qualified. The hydroxy compounds of the invention may be prepared by reacting a ketone of the formula <FORM:1015404/C2/2> with an organo metallic reagent containing the residue R1R3-CH-(where R3 is hydrogen or a lower alkyl radical) and the ethylene compounds by splitting off R0-H from compounds of the formula <FORM:1015404/C2/3> where R0 is hydroxyl or esterified hydroxyl and, if desired, replacing a hydrogen atom attached to a double bond by a halogen atom.  In the methods for the preparation of the tertiary alcohol starting materials, the latter may be dehydrated to yield the triarylethylenes directly.  A mixture of resulting isomeric compounds may be separated into the single isomers and racemates may be resolved.  2,4 - Di - (b  - diethylaminoethyloxy) - benzophenone is prepared from 2,4-dihydroxy-benzophenone and b -diethylaminoethyl chloride. Similarly is prepared 2,4-di-(2-N,N-diethylaminoethoxy) - 41 - methylbenzo phenone; 2,4 - di - (2 - piperidinoethyloxy) benzophenone and its dihydrochloride; 2,3,4 - tri - (2 - N,N - diethylamino-ethoxy) benzophenone and 2,4 - di - (2 - N,N - diethylaminoethoxy) - 41 - isopropyl - benzophenone.
