Abstract: A method for controlling combustion in a furnace into which combustible material, e.g., urban refuse, industrial waste, and a controlled quantity of combustion air are fed. The furnace includes a mixing/stirring region where unburnt gas and secondary combustion air are mixed and stirred. A part of exhaust gas derived from the furnace is blown into the mixing/stirring region depending on variation in the quantity of the secondary combustion air, and a flow rate of mixture gas consists of the exhaust gas and the secondary combustion air to be fed into the mixing/stirring region is maintained within a predetermined region so that effective combustion takes place.

Abstract: The invention relates to a balancing device for a two-component supporting arm arrangement for an X-ray unit, with a first and a second supporting arm. The one end of the first supporting arm is mounted pivotably about a horizontal first shaft on the X-ray unit. The other end is connected pivotably about a second shaft to the one end of the second supporting arm, at whose other end an apparatus is secured. In order to obtain a balancing device which is of simple and straightforward construction and is therefore relatively inexpensive, the invention proposes that each supporting arm (7, 8) be provided in each case with a lever arm (12, 13) which is part of a parallelogram system whose connection nodes (15 to 18) are arranged at the free end of the lever arm (12) on the first supporting arm (7), on the second shaft (10) and at the free end of the lever arm (13) of the second supporting arm (8), the remaining connection nodes (18) in the parallelogram system being acted upon by a force which acts as a balance for the supporting arm arrangement (7, 8) around the first shaft (9), so that the supporting arm arrangement is balanced in every position. …<IMAGE>…

IPC: D21H17/45

Abstract: Neutral sizing of raw cellulose pulp in a conventional aqueous suspension at a neutral pH for producing sized, acid-free raw paper by bulk sizing with the use of aqueous cationic copolymer dispersions having a minimum cation activity of 20  mu mol/g of solid, more than half of the cationic charge being located on the surface of the dispersion copolymer particles, in combination with polymeric retention aids, the weight ratio of the polymeric retention aid to the cationic dispersion copolymer being preferably 0.3:1 to 0.005:1, in a quantity of up to 2 % by weight of cationic dispersion copolymer, relative to the dry weight of the raw cellulose fibres. The bulk sizing is effected by intensive mixing of the neutral size components with the raw cellulose fibre suspension, with the proviso that either the polymeric retention aid is first added and the cationic plastic dispersion is then metered in, or the two agents are metered separately at the same time into the cellulose fibre suspension, if appropriate with the additional use of inert fillers, pigments, dyestuffs and conventional auxiliaries, and subsequent isolation of the acid-free raw paper in the conventional manner, if appropriate as raw paper webs or raw paper boards, and drying of the bulk-sized neutral raw paper. In the combination according to the invention with the polymeric retention aid, the cationic polymer dispersion surprisingly shows a synergistic increase in its bulk-sizing effect in the neutral pH range.

Abstract: A method and apparatus are disclosed for closed-­loop phase modulation to measure rate and control phase modulator gain errors in an electrical signal representing the phase difference between first and second light signals from lightwaves counterpropagating in an interferometric rotation sensor including a closed light path with a phase modulator (10) in the path. In the method a serrodyne signal is summed along with a gain bias signal and a rate bias signal, the result of which is multiplied with a gain signal derived from the difference between the first and second light signals. This resulting signal is then applied to the phase modulator.

Title: Pulse-driven accelerometer arrangement
Inventor: MCBRIEN GREGORY J
IPC: G01P15/125
Filed: 1990-02-22
Abstract: An accelerometer arrangement includes an acceleration sensor that includes two capacitor plates having respective parallel mutually facing major surfaces which bound a sensing gap therebetween. A plate-shaped electrically chargeable proof mass is resiliently mounted in the gap in parallelism with the major surfaces for displacement in response to the action of acceleration forces thereon out of a substantially central rest position toward one or the other of the major surfaces depending on the direction of the acceleration forces. An electrical potential difference is established between the capacitor plates to generate respective electrostatic fields between the capacitor plates and the proof mass which cause a proof mass electrical potential variation having a magnitude and sense depending on the extent and direction of the displacement of the proof mass out of its rest position. The variation is evaluated and an a pulse train that is proportionate to the variation is generated and supplied to the proof mass to establish thereat a voltage sufficient for electrostatic forces caused thereby between the proof mass and the capacitor plates to return the proof mass to the rest position thereof against the action of the acceleration forces on the proof mass.

Abstract: An improved architecture for a Prolog interpreter is described. Implicit arguments are substituted for classical explicit arguments. The implicit arguments are supported by preassigned register allocation managed by the interpreter. The interpreter also exploits improved Prolog Object processing in which the first bit of the Prolog object word is used as a flag to indicate whether the object word is a type pointer or type descriptor. Significant improvements in interpreter execution result from the usage of these techniques.

Title: Acoustic detection apparatus.
Inventor: CAULFIELD DAVID DONALD
IPC: G01N29/00
Filed: 1990-03-05
Abstract: The present invention relates to an apparatus for use in detecting the substance of an object contained within an enclosure. The apparatus is comprised of an acoustic transmitter for transmitting a pulse of acoustic energy at a first side of the enclosure. A first acoustic receiver is provided for receiving acoustic energy reflected from the object to produce a reflected acoustic energy signal. A second acoustic receiver is provided for receiving acoustic energy which has been transmitted or refracted through the object to produce a transmitted acoustic energy signal. A signal processor is connected to the transmitter and to said first and second receivers. The signal processor processes the transmitted pulse of acoustic energy, the reflected acoustic energy signal and the transmitted acoustic energy signal to produce an object signature indicative of the object. A comparator is provided for comparing the object signature with the signature of known objects to determine the substance of the object. In accordance with the present invention, ''enclosure'' is defined as being a hollow box like structure having an object to be detected and identified with respect to its substance located therein, for example, a suitcase containing an object, or a quantity of material having an object to be detected and identified with respect to its substance buried therein, for example, an object buried in the earth relatively close to the surface.

Abstract: Un filtre (10) à canaux multiples trie, classe et élimine les signaux de bruit ou les signaux indésirés des signaux d'intérêt. Le filtre effectue un traitement de signaux parallèles optiques en temps réel pour canaliser et éliminer efficacement les spectres indésirés des divers signaux d'intérêt dans un environnement de fréquences radio denses. Ceci a pour effet de transformer un canal de signaux qui est perturbé par des signaux indésirés, des interférences et du bruit en un nombre de canaux individuels qui sont taillés spectralement sur mesure pour les signaux sélectionnés d'intérêt. Le processus de filtration est effectué par modulation d'un signal porteur laser avec le signal d'intérêt et en effectuant toutes les fonctions de filtration optiquement puis en transformant par abaissement tous les signaux filtrés à leur fréquence radio d'origine. Des éléments de l'invention comprennent un modulateur acousto-optique (20), une lentille de transformation de Fourier holographique (24), un diviseur de faisceaux cubiques intégrés (28) pour produire un réseau de faisceaux de signaux (72), et un réseau de faisceaux de référence (70), un filtre à entaille adaptatif (32), un filtre de spectre de puissance holographique (34), une lentille de transformation de Fourier inverse holographique (40) et un réseau photomixeur (92).
