Patent EP-0200896-B1 (EP)
IPC: G01F1/66
Filed: 1986-03-19
Granted: 1991-01-02
Abstract: In a method and apparatus for generating a signal proportional to flow in a pipe using probes strapped onto the exterior of the pipe, two ultrasonic pulse trains at a carrier frequency are sent in opposite directions from one probe to the other. Two lower frequency signals are extracted from the two respective pulse trains and analyzed to detect a phase difference. The phase difference corresponds to a difference in the travel times for the two pulse trains caused by the flow velocity in the pipe. The two lower frequency signals are converted to digital data samples which are stored with reference timing data. A microelectronic processor synchronizes the two sampled waves, using the timing data, before comparing the sampled waves to determine the phase difference. The processor and associated circuitry also measure the travel times of the two ultrasonic pulse trains and generate an output signal proportional to flow based on the measured phase difference and the measured travel times.

Abstract: A firing mechanism with safety device for firearms, especially sport and hunting rifles and shotguns, with at least one barrel and a firing pin associated therewith and operable by way of a striker member in that the member is movable into an uncocked position, under the influence of the force of a compressed spring, against the firing pin after a trigger lever locking the striker member in a cocked position has been placed into a release position, and with at least one trigger with an associated rocker arm. In order to secure the firearm against unintended firing of shots due to external impact effects, the striker member is fashioned as a slide and is displaceable in the longitudinal direction from a rearward cocked position into a forward uncocked position. The trigger lever has an angled, curved, or like configuration and is arranged at the striker member so that it extends in the longitudinal direction and is pivotable about an axial support in such a way that, in the cocked position, the rear end of the trigger lever is secured by the rocker arm and the front end of the trigger lever rests in the forward direction on a stop fixedly formed within the frame and locks the striker member in the cocked position; this locking action being releasable by freeing the rear end of the trigger lever by way of the trigger-operated rocker arm and pivoting the trigger lever in such a way that the support of its front end at the stop is eliminated.

Granted: 1992-01-15
Abstract: The invention relates to a device for the controlled release of one or more active ingredients to a liquid, particularly a controlled release pharmaceutical tablet obtained by compressing a mixture of two granulates in a weight ratio of 30:70 to 70:30, said granulates having particle sizes of 0.4-2.0 mm. One of the granulates, the restraining phase granulate, comprises one or more active ingredients dispersed in a matrix of an insoluble substance, and the other granulate, the housing phase, comprises a soluble material and a penetration rate limiting material, one material optionally having both functions. In the compressed device, the granulates form two distinct phases, each of which is continuous. The housing phase fills large continuous pores in the restraining phase. A zero-order release rate can be obtained with the devices.

Abstract: A flat sealing ring (3) has a rectangular cross-section. As a result of the design of the sealing surfaces on the components (1, 2) to be sealed, a plate spring-like bending with simultaneously compressing deformation of the sealing ring (3) takes place, as a result of which excellent sealing is ensured, even with extremely small pressing forces. In this case, the range of use extends from ultra-high vacuum up to high pressure, and from cryogenic temperatures up to high temperatures. Because of the relatively simple geometry of the sealing edges, these can be produced extremely cost-effectively, with commercially available processing tools.
