Abstract: ABSTRACT A signal recognition system for reproducing a condition of an input signal as a condition of an output signal only when the input signal condition persists for at least a predetermined time interval is disclosed.  The system includes circuitry for periodically scanning the input signal condition.  Also included is a first memory for storing a start value indicative of the time interval, a second memory for storing a value indicative of the time already counted since the detection of a difference between the input and output signal conditions and a third memory for storing the output signal condition. A processor brings the start value from the first memory into the second mem-ory when no difference is detected and modifies the value in the second memory each time such a difference is detected and until a value is reached indicating that the time interval has been counted.  The output signal condition in the third memory is then changed.  The system is characterized in that the first memory only stores a single start value for all conditions of the input signal and the processor performs the modification in the second memory independently of the first memory.  Hence, the first memory is relatively small and does not have to be accessed each time the value stored in the memory has to be modified.

Abstract: Abstract of the Disclosure Diphenylamines or N,N'-diphenyl-phenylenedi-amines can be obtained by heat-reacting an aniline or a phenylenediamine with preferably an excess of a phenol in an amount of 4 to 20 moles per mole of the aniline or phenylenediamine in the presence of a hydrogen transfer catalyst and a cyclohexanone corresponding to said phenol.         The excess phenol used in the reaction undergoes reduction in the reaction system to form a cyclohexanone, which in turn reacts with the aniline or phenylenediamine to form a Schiff base and is thus consumed.  The Schiff base forms the intended product by means of a dehydrogen-ation reaction, and the hydrogen evolved at this time reduces the phenol to form a cyclohexanone.         The phenol present in excess thus becomes in the system a solvent, a starting material for the cyclo-hexanone, and an acceptor of the hydrogen that forms as a by-product at the time of formation of the intended product.  Hence, it becomes possible to obtain the intended product at a high selectivity from the anilines and phenylenediamines.     The process of this invention is an advan-tageous process for the industrial production of espe-cially the nuclearly substituted diphenylamines.

Abstract: ABSTRACT          SOLUBLE SURFACTANT ADDITIVES FOR AMMONIUM          FLUORIDE/HYDROFLUORIC ACID OXIDE ETCHANT SOLUTIONS     Silicon trioxide etching solutions with soluble surfact additives are provided.  The improved silicon dioxide etchants are produced by adding soluble per-fluronated surfactant additives to standard oxide etch-ants in the manufacture of integrated circuits.  These surfactant additives are unique because they remain dis-solved in the oxide etchant (ammonium fluoride/hydro-fluoric acid mixture) even after 0.2 micron filtra-tion.  In addition, the filtered solutions retain their surface active properties and are low in metallic ion impurities.  The surfactant additives provide etchant solutions with lower surface tensions, which improves substrate wetting and yields better etchant perfor-mance.  The surfactant does not leave residues or adversely affect etchant profiles.

Abstract: ABSTRACT: Method of controlling a data-processing system and data-processing system.           In data-processing systems, such as a public or a private telephone system, a data network or a computer communication network it is often necessary to simultaneously establish a purality of connections, maintaining or interrupting the same between terminals connected to the system. Apart from these communication control functions a plurality of further functions have to be carried out, such as data managements, system protection and maintenance. All these functions are regarded as processes which are worked in common with other processes in parallel by the system. In order to avoid duplication of processing means and to restrict the complicity driving in accordance with the invention is carried out that at the beginning of the data procession in the central control a process is created which will  carry out a function demanded, for example, by a terminal. Inside this process one or more partitions are created for carrying out a partial function of the demanded function, whilst to each parti-tion is allotted a local memory space, which can only be used by the partition concerned, whilst between the partition associated with the same process an information channel is created. By arranging in one process interrelated or to be interrelated system partitions (in particular terminals), an effective and economic data processing can be obtained.

Abstract: Abstract In a channel specially designed to fasten semi-rigid mineral fibre in-sulation to masonry walls, it is known to be constructed from 20 gauge galvanized steel or other suitable material.  The channel is designed to have pre-punched holes along its length for fastening of the channel to the masonry wall.  The top portion of the channel is knurled to allow easy entry of the drywall screw.  The unique feature of the channel are the teeth running along its length which are pressed into the surface of the butted together sections of the insulation providing a strong grip between the two adjacent pieces of insulation.  Of prime importance to the success of this system is the recent technological advancements of the mineral fibre itself which allows the teeth of the channel to engage the insulation fully and hold without mechanical support rather than be repelled or pushed back by the inherent nature of the insulation material.  After the insulation is secured to the masonry wall by concrete nail fastening systems, the drywall is screwed to the channel.

Abstract: ABSTRACT OF THE DISCLOSURE           A method for actuation of a gas intake or exhaust valve which is electromagnetically held in its opened and closed posi-tions by an actuator assembly having a ferromagnetic element attractable by actuating solenoids.  Control of the holding cur-rent flow through the solenoid coil is provided by a relaxation circuit element, and the excitation current is directly monitored and measured.  Upon deexcitation of the coil and relaxation cir-cuit element activation, the decay current is not measured but is instead simulated.  The relaxation circuit is supplied with pulsed current during the stationary phase of the valve, the current being measured in the pulse cycle during current supply, and is turned off upon exceeding a ceiling value.  After the decay current has reached a threshold value, the current is turned on and permitted to rise momentarily.  It is thereafter cycled off and on between an I1 and I2 value which is only about 10-20% of Imax, the capture current.
