Patent EP-0025833-A1 (EP)
Inventor: GRAF RUDOLF
IPC: H01H33/24
Filed: 1980-07-19
Abstract: A gas-blast switch provided with two coaxially arranged contact elements which can be brought into and out of engagement with one another by carrying out an axial movement. The first contact element which is connected with a drive is arranged in a fixed reference position forwardly of a blast nozzle. The blast nozzle is connected at its inlet side with a compression chamber or space which can be pressurized during the cut-off stroke of the gas-blast switch. In the cut-on stroke of such gas-blast switch the second contact element engages with the blast nozzle. The second contact element is surrounded by a screening body which, in turn, can be shifted back by means of the blast nozzle, during a cut-on stroke of the gas-blast switch, out of its advanced position in the cut-off position, against the action of a spring, along the second contact element. In order to more rapidly increase the spacing between both contact elements at the start of a cut-off stroke than such would correspond to the path of the cut-off stroke, the screening body and the second contact element are coupled with one another so as to perform opposite movements in relation to one another.

Abstract: The thermostatic operating element (7), which is usually accommodated in the setting member (6) of a thermostatic valve, is influenced by the ambient air. An increase in the temperature of the ambient air leads to the valve closing. Additionally, however, the thermostatic operating element (7) is also influenced by the heating medium, an increase in the latter being expressed in an additional closing movement of the valve closure member (21). As a result, in total the valve is closed more tightly than is justified by the temperature increase in the air. The unfavourable influence of the heating medium on the thermostatic operating element (7) in the setting member (6) can be at least largely compensated by the installation of an additional operating element (23, 24), which likewise influences the degree of opening of the valve, but is subjected to the heating medium, the operating movement of which operating element is opposite to that of the ambient air operating element (7) under a temperature change in the same direction. The additional operating element (23) can either be formed by a bimetal element (28) or an expansion member (30), the coefficient of expansion of the latter being greater than that at least of the valve spindle (15). <IMAGE>

Abstract: A method and device (12) are disclosed for preparing the skin of a patient (P) to ensure good electrical contact between a medical monitoring electrode (10) and the patient's skin relative to a reference electrode (16) secured to an already prepared site on the skin of the patient (P). The electrode (10) or the tips of the preparation device (12) includes an abrasive pad impregnated with an electrolyte for providing good electrical contact with the patient's skin. When a monitoring electrode (10) is used, the abrasive pad is secured to the skin and is rotated in a housing having an adhesive annular rim which is secured to the skin. The abrasive pad is rotatably driven by the preparation device (12) which continously measures the impedance between the pad of the electrode and a reference electrode (16) secured to a prepared site on the skin. Rotation of the pad terminates within a predetermined period or when the impedance between the pad (10) and reference electrode (16) falls to a predetermined value, whichever occurs first.

Abstract: The production of layer capacitors is rationalised in that, in the case of winding a plurality of mother capacitors above one another onto a drum having a large diameter, isolating layers (7) are wound inbetween the individual mother capacitors such that they project only by the magnitude of the thickness of the end face contact layer (3) beyond the region of the dielectric films (6). After making the end face contact, the edges (9) of the isolating films (7) are eroded away, with the contact metal adhering thereto. <IMAGE>

Le passage d'energie au travers du noyau est modifie en raison d'evenements qui se produisent dans une ou plusieurs des gaines ou dans le cas ou il n'y a pas de gaines, en raison d'evenements qui ont lieu dans un fluide ambiant. La modification resultante de l'energie transmise est une mesure de ces evenements qui a leur tour sont une mesure de l'analyte. L'energie peut etre d'un type quelconque parmi plusieurs types d'energie pouvant etre transmise au travers du noyau d'une extremite a l'autre et susceptible de modifications par reaction dans la ou les gaines ou le fluide ambiant. L'energie peut etre electromagnetique, electrique ou sonique.

Abstract: In a diaphragm pump the diaphragm separating the delivery chamber from the working chamber is clamped between a cylinder body and a cylinder cover in pressure-balancing arrangement. For this purpose a pressure-balancing space is provided to be radially outside and to encircle said diaphragm clamping surface, the pressure balancing space communicating wtih the working chamber through at least one communicating passage. Furthermore, a separate annular seal member is disposed to be radially outside the pressure balancing space chamber between the cylinder cover and the cylinder body to seal-off the pressure balancing space and the working chamber from the outside. This enables the diaphragm pump to be used at discharge pressures far greater than 350 bars and simultaneously permits the use of plastic diaphragms which are reliable in operation and have a large displacement capacity.

Abstract: In a data encoding system, digital data is encoded by adjusting the time position of each transition of a rectangular waveform with respectto to the immediately preceding transition and in dependence on the value of two bits of the digital data which can have any one of four values: 11, 10, 01 or 00. Fig. 1A shows the basic clock, and Fig. 1B the encoded waveform. Immediately after a previous transition T1, the system encodes the next pair of bits and makes the next transition at a time position T2 dependent on the value of these bits. If the bits are 00, the next transition T2 is spaced from T1 by eight clock periods. If the bits are 01, T2 can occur either at time t 7  or t i . If the bits are 10, T2 can occur either at time t 6  ort z . Finally, if the bits are 11, then T2 can occur either at time t s  or t 3 . In order to choose between the two time spacings available for the pairs of bits 01, 10 and 11, the system uses a decision map designed to keep the mean DC offset at zero and the mean time spacing constant.
