Title: Improvements in switching arrangements for automatic and semi-automatic telephone systems
IPC: H04Q3/00
Filed: 1929-12-10
Abstract: 339,496. Telefonaktiebolaget L. M. Ericsson, Rosa, A., and Johnson, K.. G. Dec. 10, 1929. Automatic exchange systems.-In order to prevent simultaneouslyoperating hunting switches S1 - - S4 from moving in synchronism and thus giving rise to double connections or to continued hunting, contacts in certain positions of the c and d banks of the switches are interconnected in such a way that if any pair of switches arrive in such a position simultaneously one of the switches is temporarily stopped until the other has taken a further step. For example, if switches S1, S2 arrive on their first contacts simultaneously, a circuit is completed over contacts 13 of the common starting relay SR, wiper d of S2, wire 9, and wiper c of S1, for test relay R1 which opens the circuit of the driving magnet D1 of switch S1. Relay R1 releases and switch S1 is restarted as soon as switch S2 has taken a step.

Title: Polymerization of higher olefines to solid polymer with lithium-titanium halide catalyst
IPC: B01J27/06
Filed: 1959-11-12
Abstract: A polymerization catalyst is formed by triturating lithium metal dispersed on an inert support with a titanium halide such as TiCl3 or TiCl4 and then elutriating, the catalyst being free from initial titanium halide.  "Trituration" is defined in the Specification as treatment of the mixture to bring it into a particle size range of 10-150 microns.  The catalyst may be treated with hydrogen or activated by heating to at least 150 DEG C. prior to use.  Specified supports are NaCl, C, TiO2, ZrO2, Al2O3, SiO2-Al2O3, sand and clays. Solvents such as naphtha may be used for trituration and elutriation. Specification 871,338 is referred to.ALSO:Alpha-monoolefins containing at least 3 carbon atoms are polymerized in presence of a catalyst composition formed by triturating lithium metal with a titanium halide and then elutrating, the catalyst being free from initial titanium halide. The lithium metal may be dispersed on an inert support.  In examples, a catalyst prepared by triturating lithium sand with TiCl3 in naphtha and elutrating with the latter was used to polymerize butene-1 and 3-methylbutene-1.  Other olefins mentioned are propylene, pentene-1, 4-methylpentene-1, 4- and 5-methylhexenes-1 and 4,4-dimethylpentene-1.  "Trituration" is defined in the Specification as treatment of the mixture to bring it in a particle size range of 10-150 microns.  TiCl4 is mentioned as a preferred initial halide and many suitable supports for lithium are also described.  The catalyst may be treated with hydrogen or heated to at least 150 DEG C. prior to polymerization. Specification 871,338 is referred to.

Title: Improvements in providing bodies with rough surfaces
IPC: C23C24/10
Filed: 1956-12-17
Abstract: Hard metal grains, or non-weldable grains coated with a layer of weldable metal are fixed to a metallic base by first spreading on the base a layer of welding material, then sprinkling on to the coated base the metal or metal-coated grains and finally sprinkling on the base a granulated heat-resistant substance such as sand and causing the welding material to melt, the said granulated substance serving to hold the metal or metal-coated grains in position during the melting operation and allow the escape of the gases resulting from the decomposition of the suspension liquid.  By "welding material" is meant brazing or soldering material in suspension in a liquid such as lignite tar-oil, said material being reduced to an impalpable powder and mixed with pickling and oxidizing agents and fluxes, also in powder form.  The granulated heat-resisting substance may be applied cold and the whole heated in a furnace, or it may be preheated, in which case it serves to melt the weldable material. Suitable metallic grains are stainless or hardened steel, or tungsten carbide; metal-coated grains include metallized diamond chips.  The process may be applied to the manufacture of grinding tools such as pestles and mortars.

[Also in Division G1] A fluid vortex-flow-sensor 7, which is connectible to the output of a vortex chamber, (1), Fig. 1 (not shown), within which a vortex flow pattern is established upon the chamber being rotated, comprises two semi-cylindrical portions 8 which anchor between them a blade-like member 15 and which are symmetrically recessed to define a central flow channel 11, and, on either side of the blade, outlet passages 13o, 14a and 13b, 14b. The central flow channel communicates with the sink outlet (6) of the vortex chamber and is intersected diametrically by the blade 15. The edge of the blade within channel 11 and facing the outflow from the vortex chamber is notched as at 16 with its edge 18 lying at an angle of between 25 and 75 degrees, and preferably at an angle of 45 degrees relative to the blade side 17.

Abstract: 1355709 Deodorizing polymer dispersions BASF AG 26 Aug 1971 [27 Aug 1970] 40064/71 Heading C3P  The deodorization of an aqueous dispersion of a polymer of an alkyl ester of an alpha, beta ethylenically unsaturated carboxylic acid optionally containing units derived from one or more other ethylenic monomers, which dispersion has an odour due to the presence of unpolymerized ester, is effected by treating the dispersion with a compound containing one or more basic non-tertiary nitrogen atoms (except ammonia and ethylene imine), which reacts with the ester to form a monodiferous product. The term "alkyl" includes substituted alkyl. Preferred compounds are those of the formula (I) wherein R is H, alkyl, alkenyl, alkoxyalkyl, hydroxyalkyl, or aralkyl and X is an aliphatic or cycloaliphatic saturated or unsaturated hydrocarbon radical containing one or more aryl groups and/or hetero atoms selected from amino and amido nitrogen atoms, and amide, ether and hydroxy oxygen atoms or a compound of general formula in which Y is -CH 2 -, -O-, -S-, or =NR<SP>11</SP>, where R<SP>11</SP> is H, hydroxy alkyl, aminoalkyl, mono- or dialkyl amino alkyl, alkyl, alkenyl, alkoxyalkyl, aralkyl or acyl, m is zero or 1 or (only when Y is -S- or = NR<SP>11</SP>) 2, and n and o are zero or integers from 1-4 provided that m = 1 or 2 when n and o are both 1, and provided that m+o equals at least 2, and provided that any methylene group may be replaced by a substituted methylene group or any pair of adjacent methylene groups may be replaced by a vinylene group. A long list of examples is given. The treatment is preferably carried out at 40-80‹ C. and pH 5 to 12. In the examples the following treatments are effected on aqueous dispersion of the polymers specified; (1) styrene/n-butyl acrylate with piperazine, dimethylamine and morpholine; (2) styrene/2-ethyl hexyl acrylate with oleyl amine; (3) styrene/n-butyl acrylate/methacrylamide/methacrylic acid with 3-(2-ethyl)-hexoxypropylamine; and (4) styrene/n-butyl acrylate/ methacrylamide with ethylamine.
