Patent DE-3043303-A1 (DE)
Inventor: SCHWENDTNER MANFRED DIPL ING
IPC: H03H11/16
Filed: 1980-11-17
Abstract: An electronic arrangement for determination of reactive power, including two transducers delivering at their outputs measuring voltages proportional to supply current and supply voltage. An additional phase shift of 90 DEG  between the two measuring voltages is produced by phase-shifting elements. A signal proportional to reactive power is produced in a following multiplier element. To preclude as far as possible variation of amplitude and phase shift occurring on frequency fluctuation in a frequency range close to rated frequency of the power supply, an all-pass is connected as a phase-shifting element ahead of each of the two respective inputs of the multiplier element whereby one all-pass is designed to produce a phase shift of +45 DEG  and the other all-pass is designed to produce a phase shift of -45 DEG  at the rated frequency of the power supply.

Title: Electrical installation apparatus having a supporting device for mounting in a waterproof surface-mounted housing
Inventor: TISCHNER HANS
IPC: H02G3/18
Filed: 1981-01-10
Abstract: The invention relates to a waterproof electrical installation apparatus having a supporting device for mounting apparatus insert, in a waterproof surface-mounted housing. It has the object of matching the apparatus insert and the housing lower part to one another such that both parts are held in the housing lower part by a clamping effect, without any special aids. In this case, the housing lower part is provided with mutually opposite guide grooves into which resilient elastic lugs on the supporting device are inserted in a clamping manner. The guide grooves are incorporated in so-called brackets which are constructed as mouldings and are used as a support for the supporting device. Since the brackets extend as far as the edge of the housing lower part and the supporting device rests on top there with the apparatus insert, there is a relatively large free space, which allows electrical conductor wires to be wired up without any problems, between the base of the housing lower part and the base of the apparatus insert.

Title: Method of increasing the measurement accuracy of a gas analyser
Inventor: EHRFELD WOLFGANG DR
IPC: G01N21/3504
Filed: 1981-04-24
Abstract: 80% of the applications of gas analysers are in the field of process automation and environmental protection and require precise determination of concentrations of gas components in gas mixtures in the ppm range, accompanied by appropriate measurement accuracy and high reproducibility of the measurements. This can be achieved by calibrating the measuring system and operation checks at closely spaced intervals of time. In contrast to the known methods, in the proposed method the light attenuation is treated not solely as a function of the partial pressure of the light-attenuating gas component, but allowance is also made for other effects which govern the light attenuation, such as gas temperature, the concentrations of various gas components, the total pressure of the gas mixture, and the gas components which alter the measured signal as a result of absorption. The advantages achieved with the proposed method are that a substantial expansion of the possible applications of gas analysers is made possible by relatively simple measures and that traces of a gas can be measured with increasing accuracy and improved reproducibility of the values even in the ppm range.

Title: Method and device for preventing accidents with semi-automatic firearms
Inventor: BUNGE RAINER
IPC: F41A17/00
Filed: 1981-12-30
Abstract: The invention serves for preventing accidents with semi-automatic firearms. It consists of a method and a device. The method is characterised by the use of a manoeuvre cartridge (a cartridge with a propellent charge, but without a projectile) as the uppermost cartridge in the firearm magazine. To guarantee the automatic reloading of the following <<live>> cartridge, the device (see drawing 1) is attached to the muzzle of the firearm. This closes the barrel, so that the case of the manoeuvre cartridge is ejected as a result of the gas backpressure and the following (live) cartridge is reloaded. The device is pierced by the projectile of this cartridge. The method, in conjunction with the device, is suitable for preventing most of the accidents occurring with semi-automatic firearms, since these are mainly caused by the first shot which, however, is not live when the method is used. <IMAGE>

Filed: 1982-03-06
Abstract: The invention relates to a method for producing two-dimensional images that can be identified only from a specific viewing angle, and to an image plate produced using the method. The production of these images is performed by resolving the image structure 10 that is to be imaged into information elements arranged in a point matrix, then sub-dividing the matrix surfaces of the overall image structure 10 into two partial matrix surfaces which each have too small a number of information elements for an optically perceptible reproduction of the image structure, and then arranging the partial matrix surfaces in a relative position such that they are mutually congruent only at a specific observer location, in which case they form the image structure 10. The image plate 1 can consist of a transparent base plate 2, on one side 3 of which there is arranged a base film 5 with information elements 7, 7a of one partial matrix surface of the image structure 10. The other base film 6 with the information elements 8, 8a of the other partial matrix surface of the image structure 10 is located congruently relative to the base film 5 on the other side 4 of the base plate 2. The upper base film 5 is designed to be transparent, while the lower base film 6 can be designed to be transparent or opaque. <IMAGE>
