Abstract: An adaptive control system is provided for an internal combustion engine. The engine has a flywheel (ll) and is connected through resilient shafts (l2, l4), and gear box (l3) to vehicle wheels (l5). The flywheel (ll), shafts (l2, l4) and wheels (l5) form a resonant system which has a particular resonant frequency for each gear ratio. The control system includes two memories (35, 38) containing fixed and correction schedules for the spark advance. The values are stored as a function of engine speed and spark advance. Values are extracted by an interpolation method and added to form command values for a dwell control device (l7). 
<??>A perturbation generator (40) generates a square waveform at a frequency which is at least three quarters of the highest resonant frequency of the resonant system. The spark advance values are perturbed in accordance with the polarity of this waveform. A window generator (43) generates a series of positive and negative windows, each window lagging a respective half period of the square waveform by a fixed phase shift. During each positive or negative window, engine fire periods are accumulated in a respective one of two accumulators (44, 45). In a slope calculation device (46), the slope of engine output with respect to spark advance is calculated from the accumulated fire periods in the two accumulators. An updating device (47) uses the slope to make corrections to the values stored in the correction schedule. Each correction is proportional to the slope and the corrections are made by a method which is symmetrical with the interpolation method used when forming the command values.

Abstract: Method and apparatus for testing hermetic seal integrity of sealed packages and containers, are provided. The method includes placing a sealed test package having at least one semi-flexible surface, within a test chamber. The pressure within the test chamber is changed from a first value to a second value, over the time interval of a test cycle. During the time interval of the test cycle, both the pressure within the test chamber and displacement of the semi-flexible surface of the test package are continuously measured, and produced therefrom, are a first analog data signal proportional to the pressure within the test chamber, and a second analog data signal proportional to the displacement of the semi-flexible surface of the test package. During the time interval of the test cycle, the first analog data signal is converted into a first discrete data sequence, and the second analog data signal is converted into a second discrete data sequence. From the first discrete data sequence and the second discrete data sequence, a correlation estimate is computed in accordance with principles of statistical analysis, as to provide a reliable measure of hermetic seal integrity of the test package.

Abstract: L'appareil et le procédé décrits permettent d'analyser un échantillon grâce à l'utilisation d'un point de virage colorimétrique résultant d'une réaction entre l'échantillon et un titrant ou de la présence d'un indicateur. Ledit appareil comprend une unité de titrage (A) commandée par ordinateur/mircroprocesseur et une cuve de titrage pourvue d'un agitateur à vitesse constante (C). Ledit appareil comprend en outre un organe détecteur de couleurs (D) capable de produire un signal électrique devant alimenter l'ordinateur/microprocesseur en réponse à un changement de couleur indiquant le point de virage d'une réaction concernant le composant de l'échantillon et le titrant. Ledit procédé consiste à régler le pH de l'échantillon à la valeur appropriée et à effectuer le titrage de l'échantillon avec un titrant qui produit un changement de couleur indiquant la forme finale d'une réaction entre le titrant et le composant de l'échantillon, que l'on détermine en utilisant un temps d'addition du titrant constant manipulé par l'ordinateur/microprocesseur. Le changement de couleur est détecté par l'organe détecteur de couleurs (D), une force électro-motrice stable acceptable pour l'ordinateur/microprocesseur étant produite. La force électro-motrice ainsi produite alimente l'ordinateur/microprocesseur afin de permettre la détermination du point de virage par l'équation de Keller-Richter ou par une équation équivalente.

Abstract: A valve unit, in particular for use at the suction inlet of a pumping apparatus, comprises a ball valve having a ball (2) and a seat (1) for controlling the flow of liquid between an inlet (18) and an outlet (19). A spring (3) forces the ball (2) into the seat (1). An actuating pin (8) projects through the valve seat (1) and contacts the ball (2). The actuating pin (8) is designed such that liquid can pass alongside the pin through a passageway (22). The armature (14) of a solenoid (12) can be pushed against a membrane (10) which is in contact with the actuating pin (8) so that the ball (2) is lifted from the seat (1) and the valve is opened. Since the opening and the closing of the valve unit can thus be actively controlled, the switching operation of the valve unit is very well reproducable resulting in a more uniform flow of the liquid delivered by a pumping apparatus connected to the outlet (19) ofthe valve unit.

IPC: C08J9/32
Filed: 1988-04-08
Abstract: The method of the present invention includes mixing a low viscosity thermoset resin and microspheres together without melting the thermoset resin and extruding the mixture to form a continuous strand of paste-like uncured material. The continuous strand is gelled on a conveyor which preferably includes a radiant heater or other means for accelerating the gelling of the continuous strands into solid form. The strands are then cut or chopped into pellet form and may be coated with an adhesive or B-staged material in preparation for forming into structural reinforcements. The pellets are filled with microspheres in the amount of 20 to 35% of resin weight. The pellets may include unexpanded thermally expandable microspheres which permit expansion of the pellets when exposed to heat to provide a pellet having a bulk density as low as 9 pounds per cubic foot. The pellets may be formed of a thermoset resin such as a polyester resin or epoxy resin, vinylester resin, polyurethane resin, or phenolic resin and may include organic, inorganic or glass pre-­expanded microspheres. Alternatively, the pellets may include unexpanded thermally expandable thermoplastic microspheres or a liquid blowing agent if expansion of the pellets is desired. A cure aid or curing agent may be included in the pellet mix to facilitate curing of the pellet in the final reinforcement and other additives may be incorporated in the pellet mix to improve extrudability or other properties of the pellets.

Abstract: The invention relates to a two-piece pipe clamp (1.1) stiffened by stiffening ribs (2.9, 3.9), with a connecting pipe (6) for a sprinkler nozzle. The heads of the sprinkler systems fitted on the ceilings of the rooms to be protected are mostly heated by local heat generation which raises the spray heads to a specific temperature and automatically brings them into operation. The planning and testing of the systems and all the parts are the responsibility of the Verband der Sachversicherer (Association of Property Insurers). The pipe clamp (1.1) to be designed in this case has to satisfy the object of ensuring an adequately stiff connection between the drilling clamp and the pipe clamp (2, 3) and of permitting simple, exact positioning of the individual drilling clamps (2). The low-loss right-angled branching through the connecting pipe (6) of the liquid flowing out of the pipe (1) is supported by means of a nozzle insert (7) of the de Laval type. <IMAGE>
