Abstract: An electro-pneumatic door-operating system in passenger transport vehicles, in particular for outer swing doors of buses. A drive cylinder (3) which can be acted upon on both sides can be connected to a compressed air source (1) via a reversing valve (2). The reversing valve (2) can assume three valve positions for the closing movement, the opening movement and a powerless state in which the drive cylinder (3) is acted upon on both sides. The powerless state is triggered by actuation of an emergency release (4). An emergency control device for triggering an opening movement of the door has a bistable relay (5) with a first relay contact (5.1) which effects the closing movement in a "CLOSED" position and effects the opening movement in an "OPEN" position and is connected to a voltage source (SP) on the one hand via the driver's pushbutton (S1) and on the other hand via a second relay contact (5.2) and an opening switch (S2) which closes in the event of an attempt at opening. The relay (5) has a T input (5.3) which is connected to the driver's pushbutton (S1) and an S input (5.4) which is connected to an emergency switch (S3). When the emergency switch (S3) is actuated, the first relay contact (5.1) is placed in the "OPEN" position and the second relay contact (5.2) closed. When the opening switch (S2) closes, the opening movement of the door is effected. <IMAGE>

Abstract: A detecting device, for example in the form of a test tube or a dosimeter having a carrier impregnated with a colour indicator for indicating a discolouration reaction, requires, to carry out a measurement, a reagent liquid stored in a separate reagent stock reservoir. To carry out a measurement, the reagent stock from the stock reservoir has to be brought into contact with the porous carrier. In order to enable a uniform wetting of the surface of the carrier exposed to the reagent solution after draining the reagent solution from the stock reservoir, provision is made for the insertion, between the carrier (5) and the reagent stock reservoir (3), of a reagent collection chamber (6) into which the reagent solution (19) discharges and is trapped therein when the stock reservoir (3) is opened and into which the carrier (5) passes for the purpose of simultaneously wetting its end face (7) which is exposed to the reagent solution (19). <IMAGE>

Abstract: The invention relates to a method for the production of an optical cable (OC), in which in each case a group of optical waveguides are mechanically combined to form a band (BD), this band subsequently being subjected to a stranding operation. The optical waveguides (LW1-LW4) are subjected to pretorsion in the formation of the band. The subsequent stranding operation is carried out in such a way that the stranding torsion occurring in the process is directed opposite to the pretorsion of the optical fibres, so that the resulting torsion of the optical fibres (LW1-LW4) in the finished cable (OC) is reduced.

Abstract: Disclosed is a system that transmits a data file between two computer systems (202, 224) using facsimile transmission. The file is converted (620) into a FAX graphical image by the transmitting system, then transmitted (622) using a standard CCITT FAX protocol, and converted (534) back to an ASCII format in the receiving computer system using optical character recognition (OCR). A significant advantage of this system is that it avoids the requirement that the two FAX facilities be capable of directly transmitting an ASCII file. Instead, the two FAX facilities need only be capable of using the CCITT standard FAX protocol. Another advantage is the elimination of the noise induced by the printing and re-scanning of the file during file transfer.

Abstract: In a power supply circuit, upon turning on of a switching element (S1), a sinusoidal resonance current flows through a series resonance circuit (4) and a smoothing capacitor (C3) of a dc output circuit (3) is thereby charged. This resonance current is reversed after a half cycle and a rectifying diode (D1) is thereby reversely biased whereby the resonance path is cut off and the resonance current is automatically ceased. While the switching element is on, exciting of an inductance and charging of a capacitor are made in a parallel resonance circuit (5), though resonance is not made therein. By turning off the switching element (S1) in a crrent zero state thereafter, a parallel resonance by the parallel resonance circuit (5) is started. The switching element is turned on at a timing when voltage of the parallel resonance circuit has returned to a power source voltage. A power supply circuit performing all switching operations at a voltage zero state or a current zero state is realized with a single power source and a circuit design thereby can be simplified.
