Title: Process for the manufacture of thermostable organo silicon anion exchangers
Inventor: WOLF FRIEDRICH
IPC: C08G77/26
Filed: 1960-07-06
Abstract: A thermostable anion-exchanger is made by condensing an aminoalkyl-siloxane or -alkoxysilane with silicic acid or an alkylorthosilicate. The process may be effected (1) by reacting the silane or siloxane with silica gel or silica jelly, e.g. by allowing the organosilicon reactant to diffuse into the gel or jelly and effecting condensation at 50 DEG  to 150 DEG C. with elimination of water or alcohol; (2) by hydrolyzing a tetraalkylsilicate together with the silane and then effecting condensation; or (3) in a modification, by alkylating silica gel with an alkylchlorosilane, chlorinating the alkyl radicals (photochemically or with sulphuryl chloride and a catalyst) and then aminating with the desired alkylamine.  In a typical example (1) silica gel was dried at 120 DEG C., covered with a -diethylaminoethyltriethoxy silane and kept for several days, after which the reaction mixture was dried for 6 hours at 120 DEG C., activated with dilute NaOH and washed until neutral.

Abstract: 1451280 Styrene-divinyl benzene copolymer production MOBIL OIL CORP 4 June 1974 [20 June 1973] 24744/74 Heading C3P A polymer suitable for use as a reinforcing filler for rubber is obtained by polymerizing styrene and divinylbenzene in a liquid slurrying medium in the presence of an anionic initiator and of a block polymer dispersing agent, to pro-  duce a finely-divided cross-linked copolymer containing functional groups which are reactive with the rubber under curing conditions. The latter requirement is achieved by (a) using a hydrocarbylalkali metal compound as initiator followed by reaction of the terminal groups with appropriate functional compounds, such as oxygen, CS 2  or benzothiazyl disulphide, (b) using an alkali metal terminated unsaturated hydrocarbon polymer (which provides the functional groups i.e. double bonds) or (c) using a mixture of the initiators mentioned under (a) and (b) optionally followed by termination with the above type of reagent. Examples refer to the copolymerization of styrene and divinyl benzene in hexane using a s-butyllithium/polyisoprenyllithium mixture as initiator and styrene-b-tbutylstyrene, styrene - b - butadiene or styrene - b - isoprene polymers as dispersant. Typical terminating agents are air, COS, oxygen followed by acetic acid, propylene sulphide and dipentamethylene thiuram hexasulphide. Paraffin wax is present during some of the polymerizations. The polymers are tested as additives in conventional SBR curing recipes.

Title: Improvements in or relating to apparatus for the measurement of complex impedance
Inventor: LAMONT KEITH
IPC: G01R27/02
Filed: 1950-10-13
Abstract: 685,006. Bridge circuits. CINEMA-TELEVISION, Ltd. Oct. 12, 1951 [Oct. 13, 1950], No. 25024/50. Class 37. A network for the measurement of complex impedance comprises in one arm a complex impedance to be measured and in the same or another arm an inverse combination of impedance elements, some at least of which are adjustable and all other arms of the network having effective impedances which are substantially invariant with frequency whereby when the adjustable elements have been adjusted so that the image transfer constant of the network over an extended frequency range contains only a real component the value of each of the inverse impedance elements bears a known relation to one of the elements of the complex impedance. In the network shown in Fig. 1a three arms comprise frequency-independent impedances R, while the fourth arm comprises the complex impedance Zx to be evaluated, shunted by a frequency independent impedance R, and a network ZB of adjustable impedance elements forming the electrical converse of ZQ and also shunted by a frequencyindependent impedance R. When the impedance of ZB is the inverse of that of Zx the image transfer constant of the network contains no imaginary component, i.e. the network has attenuation but no phase shift, then each element of the network ZB is related to a corresponding element of the network Zx in a constant manner, so that the values of the unknown impedance elements may be derived. A non-sinusoidal signal, e.g. a square wave, is applied to the terminals 1, 2 and the waveform appearing at the terminals 3, 4 is compared by means of an oscilloscope with that applied to the terminals 1, 2 and the adjustable elements of the network ZB are adjusted until the input and output waveforms are identical. Alternative networks are shown in Figs. 1b and 1c. Fig. 3 shows a circuit suitable for measuring the impedance of iron-cored inductors used at low frequencies and under conditions such that hysteresis effects are slight. Non-sinusoidal signals are applied to the primary winding 12 of a transformer having two balanced secondary windings joined by a potentiometer 13. A third arm of the bridge is formed by a resistor 14, while the fourth arm is controlled by a switch 17 and comprises either a resistor 18 or by a network comprising two parallel branches. In one branch a resistor 19, variable resistor 20, and variable capacitor 21 are connected in series, and in the other branch a resistor 22, indicator 23, variable capacitor 24, and variable resistor 25 are connected in series. The inductor to be evaluated is connected to terminals 26, 27 and comprises the resistance Rcu of the winding, the inductance L, the iron losses RFE, and the self-capacitance Cs of the winding. The capacitor 24 corresponds to the inductance L, the relation between the final value of the capacitor 24 and the value of L being CK2, where K<SP>2</SP> is the constant product of the inverse elements. The resistor 25 corresponds to the iron loss RFE.

In use, the nut 32 is tightened to provide a predetermined compressive force in the outer section 22, indicated by the registration of indicator holes 34, 35 on the nut and inner section respectively, and the bolt is passed through clearance and threaded apertures 16, 17 in parts, e.g. trunnions 14, 15 of a ring clamp 12, 13, to be drawn together, rotation of the head 23 of the inner section causing the trunnions 14, 15 to be drawn together since frictional forces entrain the outer section 22 with the inner section 21. However the resistance of the trunnions eventually overcomes the precompression and frictional forces of entrainment, and further application of torque to the head 23 merely results in slipping between the sections 21, 22. The tension applied to the outer section by the trunnions substantially cancels the precompression forces so that little or no tension remains in the outer section after application of the bolt.
