Abstract: Abstract A process for the production of a diagnostic de-vice which is envisaged, in particular, for the detection of a pathologically increased concentration of dehydro-genases in fluids of humans, animals or plants and con-sists of a carrier and a substance mixture, in which in each case with exclusion of UV radiation, the substance mixture, which has been adjusted to a pH  value in the acid range, is brought into contact, in Liquid form, with the carrier and the combination of carrier and substance mixture is subsequently dried and then enclosed in a packaging casing which is opaque to light of higher energy than red light. The process has the peculiarity that the dried combination of carrier and substance mixture in the packaging casing is securely sealed against entry of air and moisture.The device thus produced can be stored for a long time before use, without its ability to function being substantially changed.

Abstract: Abstract of the Disclosure Disclosed is an exposure device which is mounted on a base and in-cludes two exposure lamp arrangements with shutters, as well as a movable mounting support and a stationary mounting support.  The movable mounting support is adapted for being displaced between side walls by means of two compressed air cylinders.  Positioning elements, which are swivelled upward, have end faces which contact stop faces at the back of a frame of the movable mounting support, when the positioning elements adopt a horizontal position. A motor is provided for driving drive rollers.  Positioning pins which are engaged by springs are extended by the action of compressed air cylinders, in order to adjust masters provided with register perforations, on glass plates of the frames and to accommodate a plate which is to be exposed.  A vacuum pump is connected with suction means, which are arranged in the frames.  Thus the present invention provides an exposure device which renders it possible to obtain perfect exposure of two photosensitively coated sides of a vertically arranged plate, while preventing air pockets from forming between the two sides of the plate and the masters pressed against them, and which allows uncom-plicated changing of masters.

Abstract: WIRELESS TELEPHONE SYSTEM WITH              HIGH LEVEL DIAL PULSE SIGNALLING     ABSTRACT OF THE DISCLOSURE           A wireless extension telephone system includ-ing a base unit connected to a telephone line and a re-mote extension unit.  Both base and remote units each include a radio receiver and a radio transmitter.  Also included in the remote unit is a modulator connected to the radio transmitter and circuitry limiting the amplitude of modulated signals produced by said transmitter.  A dialing circuit connected to the modulator causes the amplitude of each outgoing signal representing a dial pulse to be transmitted at a level substantially higher than when no dial pulses are present.  At the base unit a dial pulse detection circuit differentiates between the modulated signals received by the associated radio re-ceiver, providing connections to the telephone line in response to signals of a first amplitude and breaking the line in response to each received pulse of a higher level amplitude.

Abstract: NORMALLY-OFF, GATE-CONTROLLED ELECTRICAL CIRCUIT    WITH LOW ON-RESISTANCE                    ABSTRACT OF THE DISCLOSURE         An electrical circuit includes a JFET serially connected to an IGFET, the gate of the IGFET constituting the gate for the circuit.  Biasing structure, such as a resistor, is connected between the circuit gate and the gate of the JFET for forward-biasing the P-N junction of the JFET extant between its gate and channel regions.  When this P-N junction is biased by more than about 0.6 volts for silicon JFET, the JFET gate region injects current carriers into the JFET channel region, whereby bipolar conduction occurs in the JFET channel region and low on-resistance for the circuit is achieved.         In a preferred circuit the biasing structure comprises an IGFET, which advantageously results in the circuit gate having a high input impedance.

After reading, the strips are moved to the waste receptacle.  Means is provided for insuring that each test strip is delivered to reading position in registration with the read head of the photometer, and means is also provided for pressing each test strip flat against the reading station platform.
