Abstract: The system is directed to preserve the starter/alternator in an IC engine installation from potential overload and failure in response to electrical load increases. The system controller monitors starter/alternator output and phase current and regulates output voltage when monitored currents reach predetermined thresholds. Output voltage is stepped down incrementally to check output currents at threshold non-failure creating levels. When current demand, i.e., load, decreases, output voltage is stepped up incrementally to return to an original set point for voltage.
Abstract: A compactly constructed locking device with a displaceable securing element fixing a detent element and actuated in a simple way into a detaining position or into a releasing position. The distance between a control cam and the securing element is selected in such a way that, with the detent element in the unlocking position, the control cam is axially displaced with respect to the control contour and is therefore located outside the range of action of the control contour. Only when the electromechanical drive is activated in order to displace the detent element into its locking position does the drive part with the control contour come into engagement with the control cam. The arrangement allows for sudden displacement into the locking position.
Abstract: The object of the invention is to provide a water immersion detecting circuit, which is free from false detection and is stable and highly sensitive in operation. There is provide a water immersion detecting circuit provided on a printed board 11 of an electronic unit and used for detecting water immersion of the electronic unit based on a change of resistance generated between a pair of sensor electrodes for detecting water immersion P10, p11, wherein the pair of sensor electrodes P10, P11 are positioned opposite to each other on the printed board 11, and a U-shaped slit (opening) 12 is formed between the sensor electrodes P10, P11.
Abstract: An electric wave shielding material provided to be adhered to a window. The material includes a body member composed of a light transmitting surface material; a light transmitting electrically conductive layer provided on the light transmitting surface material; and a light transmitting adhesive provided on at least a part of the light transmitting electrically conductive layer in such a manner that a part of the light transmitting electrically conductive layer is exposed to form a connecting electrically conductive portion. A connecting piece composed of a member for converting an electric wave into a heat energy is connected to the connecting electrically conductive portion, and includes an adhesive layer.
Abstract: An upper mixing region (210) and a lower mixing region (214) are fed with hot air via a radiator (203) and with cold air by way of respective bypass ducts (205, 208). Respective mixing flaps (212, 219) make it possible to adjust the temperature separately in the two mixing regions, from where the treated air is sent into different parts of the passenger compartment of the vehicle.
According to the invention, the two bypass ducts (205, 208) pass below the radiator (203) which makes it possible to minimise the length of the path for the hot air between the radiator and the de-icing outlet duct (221) situated at the upper part of the casing (200) of the installation, and consequently to accelerate a de-icing or demisting of the windscreen required urgently for reasons of safety.
Abstract: An embossed, decorative, man-made embossed article having an embossed surface portion containing at least about 80% by weight cellulosic fibers and sufficient binder to adhere the cellulosic fibers together into a structurally sound article having a specific gravity in the range of 0.96 to 1.08, a surface of said article having a pattern of embossed ticks stained to visually distinguish the embossed ticks from surrounding surface portions of said article, said embossed ticks formed in elongated bundles to replicate a wood grain pattern, said embossed ticks and said bundles of ticks satisfying the following criteria:
(a) at least 90% of said embossed ticks, in bundles of three or more adjacent ticks, are spaced at least 0.016 inch;
(b) at least 90% of said embossed ticks are embossed a depth in the range of 0.003 inch to 0.

Abstract: A cooling circuit for a vehicle engine, traveled by fluid under pump action, comprises a cooling branch with a radiator associated with a motor-driven fan unit, and a heating branch containing an air heater. A first device establishes a hot-starting state of the engine as a function of chosen conditions; and a second device, active in this hot-starting state, controls the speed of the pump and the speed of the motor-driven fan unit under chosen conditions, as a function of a first magnitude representative of the temperature of the fluid and of a second magnitude representative of the heating demand.
Abstract: A digitizer system includes a pointer (e.g. stylus or puck) for manipulation by a user over a work surface of a tablet. The tablet includes a menu strip area thereon. The location of the pointer on the tablet is shown by way of a cursor shape on a corresponding monitor or display which is in communication with the tablet. According to certain embodiments of this invention, the cursor shape shown on the display is changed as a function of the pointer's position within the menu strip area of the tablet. Thus, for example, a first cursor shape may be shown on the display when the pointer is over a first area of the menu strip, while a different second cursor shape may be shown on the display when the pointer is over a second area of the menu strip.
Abstract: A method for creating a releasable joint between two components wherein one of the components is elastically deformed by radial compressive forces in such a way that one effective circumferential contour corresponds to the corresponding effective circumferential contour of the other component with a predefined clearance, and the two components are fitted together. After being fitted together, a compressive joint is created by the fact that the deformed component is elastically deformed back by reducing or discontinuing the radial compressive forces. What is used as the elastically deformable component is a hollow body which has multiple cavities in its wall, and the radial compressive forces are exerted on the inner or outer contour of the hollow body located opposite the effective circumferential contour in such a way that their working lines, considered in the circumferential direction, run approximately centeredly through the cavities.

Abstract: A centrifugal pump includes a C-shaped sealing assembly including an annular spring disposed between opposing legs of a base member. The spring biases the legs away from one another into sealing positions. In other embodiments, a vertical pump may be provided so as to include an oil recirculation system which enables an oil-based lubricant to be utilized instead of grease. In still other embodiments, the axial location of a pump shaft may be adjusted by rotating a bearing housing relative to the bearing frame where the two are threadedly connected to one another.
Abstract: Apparatus for determining in-blow % carbon content and/or the First Turn Down Carbon of a BOF heat includes a light sensor housed within a temperature regulated case having a sighting window including air wipe means to shield the light sensor from steelmaking dust and fume. The apparatus also includes a means to generate a signal that corresponds to the amount of oxygen blown into the BOF during a heat, and a programmable logic controller. The logic controller is programmed to continuously process oxygen blown signals from the signal generating means, and light intensity signals received from the light sensor. The program calculates continuous in-blow % carbon content of the heat based upon the difference in light intensity from a point of maximum light intensity emitted from the BOF vessel in relation to the amount of oxygen blown into the BOF vessel during the same period of time.
