Abstract: A moisture sensor device for detecting the degree of wetting of a transparent pane by drop-shaped precipitation. The sensor device is provided with a beam guide element, which is affixed to the pane by an optical adhesive. A beam transmitter and a beam receiver are each associated with a lens. Such a sensor device solves the problem of guaranteeing optimum conditions for the generation and output of rays into and out of a beam guide element. Aspherical lenses are associated with and arranged at a short distance from the beam transmitter and the beam receiver. Each lens has a surface facing the beam transmitter or beam receiver which in outline is fashioned according to a polynomial selected to be equal to or greater than the third degree and is developed to form a body of rotation.

Abstract: In a bath rim fitting or other fitting, in which a shower hose extends through a plate or the like and whose back is difficultly accessible, it is proposed to connect the shower hose to the fixed pipe with the aid of a pressure hose. The pressure hose is sufficiently long that it can at least be drawn up to the plate opening by pulling on the shower hose, so that it is possible to replace the latter in front of or outside the plate.

Abstract: A rack for a control cabinet comprising a plurality of frame pieces which are connected to each other in the area of the rack corners. A quickly and easily assembled rack with high torsional stiffness is created where the front horizontal and vertical frame pieces as well as the rear horizontal and vertical frame pieces are miter-cut on both ends and fixedly welded together to form a front and rear frame. The frame pieces used as depth braces are closed off on both ends by fastening plates provided with at least two fastening screw receptacles. Correspondingly distributed through-bores are cut in the corner areas of the frame. In each corner area of the frame, a cover plate is fastened on the frame by fastening screws. The fastening screws are inserted into fastening bores of the cover plates and screwed through the through-bores of the frame into the fastening screw receptacles of the fastening plates connected to the depth braces.

Abstract: A double-layer pipe bend for a pipeline includes an inner pipe of cast steel, an outer pipe of weldable steel surrounding the inner pipe, and connecting flanges at the ends of the pipe bend. The connecting flanges are welded to the outer pipe. The inner pipe and the outer pipe are formed such that a pressure-compensating layer can be formed by the transported medium between the pipes. Another pressure-compensating layer can form between an inner wearing ring and an outer coupling ring of each connecting flange. The wearing ring and, thus, the inner pipe, is axially secured by a groove in the wearing ring and a radial collar in the coupling ring.

Abstract: An apparatus and method for controlling a windshield wiping system, based on a connection threshold defined for starting operation of the windshield wiping system, a disconnection threshold defined for ceasing operation of the windshield wiping system in an intermittent mode of operation, and a disconnection threshold defined for ceasing operation of the windshield wiping system in a continuous mode of operation. The apparatus includes a sensor apparatus and a circuit arrangement. The sensor apparatus which generates a signal the value of which varies based on the degree of liquid or dirt on the windshield. The sensor signal is then processed by a microprocessor. The thresholds are defined based on the sensor signal.

Abstract: The physiological parameters of heart rate, respiratory and snoring sounds, the degree of oxygen saturation of the blood, and the bodily position of the patient are measured and stored in coded form by means of portable apparatus. The stored data are transferred to a computer and then analyzed. The mobile apparatus comprises a detection and storage unit (2) and the following pickups: three EKG electrodes (3), one laryngeal microphone (4), an oximeter-finger sensor (5) and a position pickup (6). The apparatus permits an ambulatory diagnosis of sleep apnea which is comparable in its meaningfulness to diagnoses based on stationary sleep laboratory tests for sleep apnea.

Abstract: A method for controlling a vehicular windshield wiping system, the wiping system being controlled in response to recognition of a particular rain pattern, and being capable of distinguishing between the presence of moisture and dirt on the windshield. The wiping system is also controlled according to a plurality of operating thresholds established to ensure smooth operation of the wiping system during varying conditions, and is controlled according an amplification autoranging strategy to ensure the wiping system functions properly independent of certain conditions, such as the type of windshield on the vehicle. The wiping system includes at least one wiper blade, and a sensor mounted to the windshield for monitoring a portion of the windshield. The sensor generates a signal having a value which varies as both moisture and dirt collect on the monitored portion.

Abstract: A keyboard has keys arranged in parallel columns with all of the keys in a respective column projecting from a front plate the same distance. The keys of a first column are arranged to project a smaller distance from the front plate than the keys of an adjacent second column.

Abstract: A motor-vehicle door latch has a bolt projecting from a support and movable by an actuator between an advanced and a retracted position, and a housing movable between an open, a partially closed, and a fully closed position. A latch fork can engage the door bolt to retain same and lock the door. The servoactuator can, when the bolt is engaged with the fork, move the housing between the partially and fully closed positions. A pawl pivots on the housing between a holding position retaining the fork in the latched position and a freeing position permitting the fork to move out of the latched position. A release lever on the housing displaces the pawl from the holding to the freeing position. A opening lever on the housing operatively engageable with the support is coupled to the pawl for moving it from its locked to its unlocked position on movement of the opening lever from a cocked to a rest position.

Abstract: Calcium sulfate alpha hemihydrate and foundry sand are milled to cement fineness and form a hydraulic binder, as a mixture with both high early setting strength and excellent water resistance. The composition relies upon a sulfate activation of the foundry sand rather than an alkali activation thereof.

Abstract: A closure device for drinking from a liquid container (2) is sealingly mounted with a bottom part (3) of a main body thereof extending into an opening of the container. A top part (4) has a circular-arc portion with a groove (6) therein. Liquid-emitting and air-admitting bore holes (10, 11) are positioned in a base of the groove. A pivotally movable cap (14) is mounted on the top part covering the groove. When the cap is pivoted, it causes a flexible hose (12) mounted in the liquid-emitting bore hole to bend and thereby closes it. At the same time, the bent hose closes the air-admitting opening.

Abstract: A hand brake for a motor vehicle includes a hand lever pivotably supported on a support bracket fixed to the vehicle body, and an adjusting disc likewise supported on the support bracket and connecting the hand lever with a pull member leading to a wheel brake shoe. A detent pawl supported on the hand lever cooperates with a toothed segment formed integrally with the support bracket and is released with an actuation rod longitudinally displaceable in the hand lever. The hand lever is connectable with the adjusting disc by a coupling pawl supported on the hand lever and slidably engaging a guide pin secured to a side surface of the support bracket. The adjusting disc is springbiased in the rotational direction so that it provides for progressive pull member displacement/force ratio.

Abstract: An arrangement for fixing a clamp to a C-shaped rail comprises a fixing plate urged against inner arms of the rail by a compression spring, the plate having a width which fits between inner arms so that it can be inserted from above, and a length, which fits between the arms of the C-shape, diagonally opposite portions of the ends of the plate being shaped to permit it to rotate between the arms of the rail. The spring is located between the head of a spigot fixed to the fixing plate and a supporting plate. The ends of inner arms are arranged to be located in grooves in the fixing plate.
