Abstract: 1. Method for the control of the purification process in the purification of the filter material of textile rejection filters, preferably of the bag filter type, wherein the contaminated gas of a filter chamber is led in via a raw gas inlet and the filter material installed in the filter chamber, passes under the deposit of dust on the filter material and is drawn away from the filter chamber through a clean gas outlet and the purification is effected in such manner that the filter material is exposed to a compressed air impulse from a purification system, which is controlled by a control system, which senses with measuring elements the pressure drop (Pf ) across the filter material, characterised in that the control system also senses the filter loading (Vf ) which consists of the quotient of the gas flow and the filter area, and forms the quotient of Pf and Vf , i. e. the filter resistance(s), which upon comparison of the filter resistance with a desired value (S0 ) produces a signal for the control of at least one of the parameters which influence the purification effect on the filter material of the purification system.

Abstract: A frame for holding a member of laminar form comprises a series of edge members (3) each of which has at least one internal, longitudinally extending cavity (7a,7b) bounded by an external wall of the edge member. The external wall is resilient and has a longitudinal slit (8a, 8b) which can be opened to admit the edge of the laminar form member by depressing the wall.

Abstract: Highly purified isobutylene, up to 99.9% pure, is obtained by treating a reaction mixture such as that recovered from an isobutylene-containing hydrocarbon mixture also containing an aqueous solution of an aliphatic carboxylic acid having 1 to 6 carbon atoms that has been reacted in an acidic ion exchanger and from which the unreacted hydrocarbons have been removed. The operative ingredients of the treated mixture are tertiary butyl alcohol, secondary butyl alcohol and their esters of the carboxylic acid employed. When treated with an acidic ion exchanger the carboxylic acid isfirst formed which inhibits the secondary butyl alcohol and secondary butyl ester of the acid from decomposing and high purity isobutylene is recovered therefrom by conventional distillation.

Abstract: The present invention provides a two component resin coating system which when mixed forms a curable coating composition. The first component comprises a polyamine terminated polyepoxide adduct which has been salted with a controlled amount of acid. The salted adduct is dissolved in a co-solvent having a specifically defined solubility parameter polar component and water. The second component comprises a low molecular weight water insoluble polyepoxide cross-linker which is optionally dissolved in the selected co-solvent. When the two components are blended together, the polyepoxide resin cross-linker is dispersed in the microemulsified state throughout the salted adduct solution and the resulting composition exhibits improved pot life, freeze-thaw stability, and film forming properties.

Title: Object and person identifying and information transmission system
Inventor: VOGEL KLAUS DIPL-ING
IPC: G01S13/74
Filed: 1981-01-20
Abstract: The system consists of a reader (LG) and an identification carrier (identification arrangement KA) attached at the object to be identified or at the location of information storage, which carrier(s) radiates the electromagnetic read signals coming in from the reader (LG) back to the reader (LG) with a plurality of delayed echoes, representing the information content, via a radio field (F). The identification and information transmission should take place in an interference- and forgery-proof manner and with a simple configuration of the system. For this purpose, the invention provides that frequency-, phase- or amplitude-modulated read pulses are transmitted from the reader (LG) to the information carrier (identification arrangement KA) and that echo pulses representing the information content are radiated back with a delay time  tau x, with the minimum delay not being less than  tau 0 with respect to the read pulses and which echo pulses have a predetermined signal/noise ratio compared with noise reflections triggered by the read pulse and coming from more distant noise reflection points. In the reader (LG), the received echo pulses are supplied, after corresponding demodulation and amplification, to subsequent evaluating circuits via a time window switch (12) controlled by a clock processing circuit (T), and distributed to fixed bit positions. A system according to the invention is suitable for identification arrangements of all types, for example also in traffic systems. <IMAGE>

Abstract: Apparatus and method for chromatographic separation and quantitation of different ions of like charges in a sample, e.g., cations or anions. Referring to anion separation, a sample including at least one highly ionized (strong) weak anion and at least two poorly ionized (weak) cations (or vice versa) is directed with a developing reagent through an ion exchange separation column in which the weak anions, separated as a group from the strong ones, are directed to a suppressor ion exchange bed in which the developing reagent is converted to a weakly ionized form. The strong acids are directed to an anion concentrator column which retains the anions but pas- sesthe remainder of the solution. Thereafter, the weak anions are dissolved in a developing reagent and separated on a chromatographic separation column.The resolved anions are then directed to a detector. If the detector is of the type employing a conductivity cell, the solution is passed through a second suppressor column prior to the detector.
