Patent EP-0007781-A1 (EP)
Inventor: KUMMEL WINFRIED
IPC: H04R3/00
Filed: 1979-07-19
Abstract: The invention concerns a method of controlling the current supplied by a current source to a load. The current is supplied to the load 12 via a first conductor 11 from the current source 10 and the current in the first conductor 11 is monitored by a second conductor 13 disposed alongside the first so that a current is induced in the second conductor 13 which is proportional to the current in the first conductor 11. The signal in the second conductor 13 is fed back to control the supply of current by the current source 10 in dependence upon the behaviour of the induced signal. 
     The invention is applicable to the short circuit protection of amplifier end stages and the control of loudspeaker amplifiers in the resonance frequency region.

Abstract: Au cours de ce procédé, une quantité d'un mélange expansible est coulée dans un moule (1), après quoi, le moule est obturé à l'aide d'un bouchon (16) à travers lequel une dépression est créé dans la chambre (4) du moule (1) pour permettre le moussage du mélange. La dépression est maintenue un certain temps après que le mélange moussant ait rempli la totalité du volume du moule. A la fin de la période de polymérisation du mélange moussant, la dépression peut être ré-appliquée au moule, de préférence pendant plusieurs cycles pour provoquer l'éclatement des cellules de la mousse obtenue.

Abstract: L'invention concerne un procédé de préparation de sels d'aryldiazonium en solutions aqueuses. Le procédé selon l'invention est caractérisé en ce que la réaction de diazotation est réalisée par des vapeurs nitreuses (mélange NO ; NO2 ; N2O3) riches en NO (rapport molaire NO/NO2 à l'équilibre compris entre 2 et 100). Le rendement en sel d'aryldiazonium est quantitatif par rapport à l'amine et par rapport aux vapeurs nitreuses transformées. Les solutions aqueuses de sels d'aryldiazonium peuvent être utilisées de manière classique. Elles ouvrent l'accès aux composés amino-azo-aromatiques.

Abstract: A Schottky collector transistor (PNM) inverter circuit is used to implement a positive logic, multiple input, single output NAND gate or a single input, multiple output NOR gate. The NAND function is achieved by merging two PNM inverters in a common emitter configuration, such that the common emitter also comprises the base of a dual collector NPN load transistor, and each PNM base comprises an NPN collector. Circuit densities are approximately double the densities of comparable 1 2 L configurations. Both speed and speed-power product are improved over conventional I-L (Fig.2).

Abstract: The back flow stop has an inflow connection piece (2) and an outflow connection piece (3) coaxial to the latter. Its valve (24) is formed by the sealing ring (23), acting as valve seat, and the closure member (20), displaceable along the supporting rod (14). A loading spring (16) inside the pot-shaped closure member (20) is supported by its one end (17) against the pot base (19) and by its other end (18) against a supporting member (15) which is firmly connected to the supporting rod (14) and is hence fixed relative to the housing (1). The closure member (20) is moved from its upper displacement end position into its lower displacement end position by the hydraulic pressure, counter to the force of the loading spring (16). Its lower end interacts with a sealing ring (27) in the lower part (7) of the housing and, with the latter, forms a drain valve (28). The latter is closed shortly before the opening of the valve (24), with the result that the water entering via the connection piece (2) can only flow off via the outflow connection piece (3). If the admission pressure is too low or there is a flow reversal, the drain valve (28) opens and the valve (24) is then simultaneously closed. Penetration of back flowing water, which is generally contaminated, into the inflow connection piece (2) is thereby prevented. <IMAGE>

Abstract: A powered dental scaler is disclosed of a type which drives a vibrating scaling tip (26) in a circular or ellipsoidal pattern of motion. A scaling tip (26) having working surfaces provided by the edges (104,106,108) of an elongated, curved element which has a cross-sectional configuration in the shape of a multi-sided figure, e.g., a triangle or a diamond, is particularly useful with a scaler having this type of vibrational pattern. Each of the longitudinal edges (104, 106, 108) has a radius of curvature in the range of about 0.025 mm to about 0.127 mm. The free end (94) of the scaler work tool (26) preferably terminates in rounded or ball-shaped configurations, and the working surfaces can be joined along inactive edges by a convex surface to provide "safe" surfaces. The absence of sharp edges or points on the scaler tool work surfaces substantially reduces the likelihood of damage to tooth dentin, cementum or gums.

Abstract: The present invention is intended to solve the problem of the reliable acquisition of accurate temperature data for a miniature calculator provided for the application of family planning methods. The calculator is provided with a receptacle removably carrying a thermometric probe for providing the temperature measurement in a digital form. The circuits of the probe comprise an oscillator including a temperature responsive resistance element to be placed in contact with the area of the temperature to be measured, Tx. The output frequency fx of this oscillator is a function of Tx, and is measured by a counter controlled by a signal formed from a reference frequency fr provided by a reference oscillator and further provided to a frequency divider. A comparator compares the contents of the counter to that of a memory, and in case the counter contents is higher than the stored contents, the comparator controls the entry thereof to the memory so that the probe operates as a maximum thermometer. The contents of the memory is read in serial fashion by the system of the calculator when the probe is replaced into its receptacle.

Abstract: A Soren-rotor expansion engine having two Soren-rotors (25) on parallel axes, the mutually engaging blades and slots of the screw pitches of which form expansion cells, of continuously changing volume, on rotation, which alternately and intermittently come into connection with the connecting openings of a compression and ejection channel, that is to say the inlet and the outlet opening (11, 12) for the driving medium, which openings are arranged in each case in one of the two inner housing or transportation chamber end walls (9, 10) which would otherwise be virtually contacting the rotor end faces. On one of the end walls of the transportation chamber a moveable closure device (20, 22) is provided with which the cross-section of the relevant connecting opening, or the angle range in which one of the channels is connected to the expansion cells formed by the blades and slots, can be varied in terms of its position and/or extension in the circumferential direction of the rotation. In the end wall on the low-pressure side, the inlet opening can be closed by two control plates (20, 22) moveable counter to one another, which are each allocated to a rotor. The closing movement of the control plates takes place as a reduced ratio of the closing angles. The control plates are adjustable via a toothed drive (34, 37, 38). <IMAGE>
