Patent EP-0002965-A1 (EP)
Inventor: CISCO THOMAS FRANCIS
IPC: C07D307/68
Filed: 1978-12-28
Abstract: Chlorination of an acid with a chlorinating agent produces a reaction mixture from which the desired acid chloride may be recovered by distillation. In the chlorination and distillation, by-products, polymers and degradation products may be produced which can cause a decrease in the yield of the desired acid chloride. A particular problem arises from the tendency of acid chlorides to degrade and/ or polymerize when subjected to excessive temperatures for long periods. An improved process for recovering an acid chloride from a mixture containing the acid consists in distilling the acid chloride from the mixture in the presence of an effective quantity of a distillation improvement additive, such as an organo polysiloxane or a mineral oil, which remains substantially liquid under the conditions of distillation. In this way the problems referred to are reduced or overcome and increased yields of acid chloride are obtained.

Abstract: An apparatus for providing a continuous supply of web material to a web printer or other system. It is necessary to achieve this so that a printing operation, for example, may continue in uninterrupted fashion even as successive rolls of printing paper or other web material are depleted. The web material is fed from a first roll (36) supported in a feed position, and when the first roll is near depletion, the leading end of a second roll (36) is adhesively connected to the web of the first roll with that web then being severed. One belt drive means (48) is employed for rotating both the forward and rearward rolls so that these achieve the same speed for the connecting and severing operations. The belt drive means are connected to the press drive through control means (73) which vary the belt drive speed in accordance with the tension of the web. An indexing conveyor (30, 32) supports forward and rearward rolls to locate the rolls in the forward and rearward running positions and in intermediate positions for connecting and severing of the web material and for loading of new rolls into the system.

Abstract: To evaluate information items stored in digital archives, the search for the stored information items is usually conducted by means of a comparator circuit to which digital recognition signals are to be applied, on the one hand, and, on the other hand, the digital data archive is to be connected. It is then the object of the invention to specify a replacement for the usual comparator circuits which, above all, provides the possibility of an accelerated sequence of the search process compared with the previously known possibilities. For this purpose, it is proposed that each cell of the matrix store (DKS) forming the digital archive is in each case combined with one circuit section (T9, T10, T7, T8) forming one comparator cell. It is also proposed that in this arrangement, the signal outputs (KA) of the comparator cells of the individual matrix rows (ZI) are in each case connected to a common signal output (KZi) in each case allocated to the relevant matrix row. <IMAGE>

Abstract: The transverse and longitudinal termination impedances of a subscriber line interface circuit may be independently controlled. The equivalent termination impedance of a subscriber line/trunk appearing to the central office can be adjusted upward or downward from a lower resistance value, with longitudinal balance being determined by the matching of feed resistors. The circuit is implementable as a monolithic integrated circuit having low power dissipation, improved power bandwidth requirements, and lower voltage breakdown requirements for integrated circuits; all resulting in an improved telephone line interface circuit. Voltage or current feedback to synthesize the proper ac transverse termination impedance from a known dc resistance, is utilized, the feed resistors in a telephone line circuit. The transverse and the longitudinal termination impedance are determined by choice of feed resistance value. The independent control of transverse impedance is achieveable as a result of the feedback circuitry being nonresponsive to longitudinal signals

Abstract: A method for the production of a more water-resistant foamed element from waterglass consisting essentially of the steps of mixing together a major amount of an alkali metal silicate solution, with inorganic fillers, at least one alkali-resistant wetting agent in an amount sufficient to form a stable foam, at least one compound capable of hardening a waterglass foam in an amount sufficient to cause said alkali metal silicate to harden, and sufficient natural latex dispersion to cause the foamed element to have a greater water resistance, mechanically foaming said mixture by the incorporation of an inert gas thereon, filling the resultant foam into an element form capable of disassembly, curing said foam in said form, and recovering a more water-resistant foamed and cured element. Preferably the natural latex dispersion is employed in a 50% dispersion in an amount of from 0.2% to 30% by weight, preferably from 0.2% to 10% by weight, based on the total mixture. The alkali metal silicate solution used has, in the case of sodium silicate, a solids content of about 27% to 43% by weight at an SiO2/Na2O molar ratio of about 4 : 1 to 3 : 1 and in the case of potassium silicate a solids content of about 20% to 36% by weight at an SiO2/K2O molar ratio of about 4 : 1 to 3.4 : 1, it being possible to use any desired mixture ratios of the mentioned alkali metal silicates. The mixture may optionally contain an addition of 0.1% to 2.5% by weight, preferably from 1% to 2% by weight of B2O3. Preferably the wetting agent added to the mixture is an anionic tenside, such as a sodium C14-16 alkylsulfonate, in an amount of from 0.1% to 10% by weight, preferably from 4% to 6% by weight in the form of a 30% aqueous solution. The fillers to be added to the mixture are inorganic compounds of light specific gravity in a grain size up to 0.1 mm and in an amount of up to 50% by weight, preferably from 10% to 20% by weight. The hardeners are preferably proportioned into the mixture during foaming in amounts of from 1% to 10% by weight, preferably from 2% to 6% by weight. The preferred hardener is glycerine triacetate.
