Patent EP-0440867-A1 (EP)
Inventor: BAUMGAERTNER MANFRED DR-ING
IPC: G01F1/66
Filed: 1990-02-09
Abstract: An ultrasonic flow measuring tube (1) for measuring the speed of a fluid flowing through the measuring tube is constructed with a rectangular cross-section. The lower measuring tube wall (4) supporting the measuring transducer (7, 8) has a U-shaped configuration in longitudinal section, and its limbs are formed by two bevels (5, 6) arranged at a distance from one another and facing each other. The measuring transducers (7, 8) are inserted into these bevels (5, 6) in such a way that their insides form a plane surface. The angular position of the bevels (5, 6) is selected such that the ultrasonic beam (9, 10) of the respectively transmitting ultrasonic transducer impinges vertically on the diaphragm of the respectively receiving ultrasonic transducer after simple reflection at the inside of the opposite upper measuring tube wall (11) or after multiple reflections on the insides of the upper and lower measuring tube walls (4, 11). <IMAGE>

Abstract: Process for manufacturing plastic-sheathed pipe couplings by injection moulding, in which an inner socket element, provided with a thread for screwing in a fitting, is coupled in a torsionally resistant manner to an outer plastic socket element in an injection mould. This process is to be further developed in such a way that, with comparatively little outlay, a permanent coupling is achieved between the inner socket element, provided with a thread for screwing in a fitting, and the outer plastic socket element, which coupling remains completely tight even under extreme mechanical and thermal loads. This is achieved by the outer plastic socket element being injection moulded from a low-melting olefin material, whereupon a core element, the outer surface of which corresponds to the inner surface of the pipe coupling to be manufactured, is inserted into the socket bore, and then a higher-melting olefin material is injected between the core element and the inner surface of the plastic socket element in order to produce the inner socket element, the said higher-melting olefin material melting the surface of the outer plastic socket element and fusing with it.

Abstract: A heat and moisture exchanger has an element 4 formed by a strip of bacterial filter material that is folded laterally into pleats and bent into a loop so that the folds 41 and 42 extend radially. The element 4 is sealed around its outer edge into a circular casing 1 having axial, tapered ports 2 and 3 at opposite end. A conical gas diverter 46 and 47 is sealed into a central opening of the element 4 on each side.

Title: Photodiode array

IPC: H04N1/028
Filed: 1991-06-20
Abstract: A photodiode array comprises a plurality of n channels, each channel having a photodiode (1) which is reverse biased such that it acts as a current source (2). Each channel further comprises an A/D converter for providing a digital output signal (DATA) which is representative of the photocurrent (Iph) provided by the photodiode (1) and therefore of the intensity of the light impinging on the photodiode (1). The A/D converter comprises a controllable current source (5), an integrator circuit (3,4) , a comparator (7) for comparing the output signal (Vout) of the integrator with a predetermined signal (Vthreshold), a logic circuit (6) for controlling the current source (5) in response to the output signal (Vcomp) of the comparator (7) such that Vout is kept within a certain range. Preferably, the current source (5) provides current in the form of charge dumps to and/or from the integrator (3,4). The number of dumps in one direction is counted by a counter (8) and is a digital measure of the photocurrent (Iph). The photodiode array is particularly useful in spectrophotometers since the provision of a separate A/D converter for each channel allows simultaneous processing of all the photosignals in the array so that spectra distortions arising from time delays in processing the photosignals are avoided.
