Title: Measuring time average values - is for improved control response, using digital sampling and continuous integration, within limits
Inventor: BECK HANS-PETER DIPL ING
IPC: G06J1/00
Filed: 1980-11-26
Abstract: The arrangement is for measuring the time average of analogue measurement values and enables rapid continuous measurement of effective values, real and imaginary components, apparent power and time dependent Fourier coefficients. It enables the dynamic response of control loops to be improved, esp. in the initial build-up period to be made. The measurement value or Fourier coefficient, if required after multiplication by analogue input parameters, is converted into time discrete form using a clocked (2) sample and hold circuit (1) with a certain sampling rate. The output of the sample and hold circuit goes to an analogue to digital converter (3) which drives a first adder (5) and a shift register (4) whose number of stages equals the measurement period divided by the sampling rate. The circuit contains further summation and register circuits, a factor element (6) and a feedback loop.

Patent DE-3123178-A1 (DE)
Title: Digital measurement converter
Inventor: BORST HUGO DR DIPL ING
IPC: G01R19/12
Filed: 1981-06-11
Abstract: The digital measurement converter converts the stochastic signals output by a detector for ionising radiation, particularly pulse signals, into smoothed signals. It exhibits a digital number store (21) in the processing path of the detector signal. The storage content n of the number store (21) is repetitively changed at time intervals  DELTA tn by a numerical value  DELTA n in such a manner that the quotient qn =  DELTA n/ DELTA tn depends on the storage content n over a number of changes in the storage content n through the numerical value  DELTA n, at least in the mean. Such a digital measurement converter allows the approximately continuous processing of detector signals, the measurement information contained in the detector signals being transferred approximately without time delay to the output signals of the measurement converter. By appropriately designing the processing path, the stochastic detector signals can be subjected to different conversion processes such as, for example, to the continuous smoothing of the stochastic detector signals, the continuous smoothing of a number of detector signals to be linearly combined with one another, the time differentiation of detector signals to be smoothed, the continuous statistic estimation of the time integral of a smoothed detector signal and the multiplicative combination of detector signals with other signals supplied to the measurement converter but not stochastic. <IMAGE>

Title: Device for the uniform distribution of a two-phase flow
Inventor: PICKERT DETLEF
IPC: F02M69/50
Filed: 1981-06-12
Abstract: The invention relates to a device for the uniform distribution of a two-phase flow fed via an inflow line and containing a liquid and a gaseous component, in particular a two-phase flow of a fuel-air mixture, consisting of liquid fuel and air, of an internal-combustion engine, over several outflow lines. In order to obtain as accurate and as uniform a distribution as possible of such a two-phase flow over the outflow lines with simple and not very complicated means, the inflow line and the outflow lines arranged symmetrically to the inflow line are to be connected via a distribution space whose cross-section of passage is dimensioned in such a way that the pressure in the flowing mixture remains essentially constant upon entering the distribution space. It is expedient here if the distribution space is of essentially disc-shaped design and if one end face of the housing enclosing the distribution space is designed as a piston adjustable against a spring. <IMAGE>

Patent DE-3134565-A1 (DE)
Title: Rod shears
Inventor: WEPNER JOACHIM
IPC: B23D23/00
Filed: 1981-09-01
Abstract: In rod shears, material is displaced by the penetration of the blades into the workpiece, as a result of which both the sheared-off section and the remaining rod part attempt to escape forwards or backwards out of the shearing zone. Since rod holders have to be provided in the interest of a shearing plane running at right angles to the longitudinal axis of the rod, an elastic stress builds up first of all between the rod holder and the blades during the shearing operation. During the further shearing operation, the elastic stress results in impact loading of the blades and non-uniformity of the material in the area of the shearing plane. The invention enables unintentional faults of this type to be rectified owing to the fact that the rod holder cannot only be pressed in the vertical direction onto the rods but in addition can also yield in the pressed state in the opposite direction to the feed direction of the rods by such an amount as corresponds to the elongation of the workpiece during the shearing. The rod holder is advantageously of two-piece design in the form of a holder slide and a holder base, and both parts are displaceable at right angles to one another. Here, the holder base can move against the force of tension springs in the horizontal direction relative to the holder slide and thereby enables the rods to slide back during the shearing without having to dispense with the pressure applied to the rods in the vertical direction.
Patent DE-3139389-A1 (DE)
Title: Spectacles
IPC: G02C5/18
Filed: 1981-10-03
Abstract: In known spring hinges a spring mechanism is accommodated in a small housing in the interior of the hinge region. This device is expensive and also not entirely operationally reliable, since the springs can break. Because of the relatively large housing, the system is suitable only for bulky spectacles, because then the spring hinge mechanism does not stand out. The invention produces in a simple way an aesthetic spring hinge that is constructed from simple components, has a long life, and can also be used without changing the frame. The bow rising angle can be adjusted as previously. According to the invention, this is achieved when a second hinge half is provided behind a second bow riser surface in an inwardly open niche which is a little longer than this second hinge half, a longitudinal guide device is provided in the longitudinal direction of the straight region of the ear bow on the second hinge half and in the niche, there is provided in the niche and on the second hinge half in each case a stop surface such that when it is stopped the second hinge half is in its hindmost position and the bow riser surfaces touch one another, the stiffening rod, which is anchored at its end region in the ear bow, is connected to the second hinge half and mounted in an axially displaceable fashion in a longitudinal bore of a first sublength of the ear bow, the first sublength is followed by a compression element whose front end face bears against the rear end face of the first sublength and whose rear end face bears against the front end face of a second sublength, situated further behind, of the ear bow, the distance between the rear end face of the front sublength and the front end face of the rear sublength being smaller than the length of the unloaded compression element, and the stiffening rod passes transversely through the compression element and is firmly anchored in the second sublength. <IMAGE>

Title: Method for producing a diet beer
IPC: C12G3/08
Filed: 1981-11-12
Abstract: The invention relates to a method for producing an alcohol- and calorie-reduced diet beer which is low in carbohydrates, wherein wort is fermented in such a way that the fermentable carbohydrates and the dextrins, which ferment only with difficulty and which are converted into fermentable carbohydrates by an addition of diastase solution, will have been fermented to leave not more than 0.75 metabolisable carbohydrates per 100 ml of beer and the alcohol content of the beer is reduced in vacuo. In order to produce a diet beer with a high wort content in an energy-saving method without adversely affecting its flavour, the alcohol content of a beer which has been brewed from a wort with an effective original wort content of 7 to 8% is concentrated to the level of a beer with a high wort content in such a way that the beer is treated briefly in a thin-film evaporator at a temperature of approx. 30 DEG C to approx. 50 DEG C for a period of 1 to 10 seconds.

Title: Housing for power connecting relays in telephone systems
Inventor: UEBERLEE SYLVIA
IPC: H01H50/02
Filed: 1982-03-04
Abstract: The invention relates to a housing for power connecting relays in telephone systems comprising a baseplate, a printed circuit board inserted therein, a protective cap and a cover panel with an inserted central panel or with a covering cap. This housing is to be reduced to such an extent that the connecting relay can be inserted in an empty housing to DIN 49073, thus allowing flush-mounted installation. Despite the reduction in the external dimensions, the creepage paths and clearances between the soldering eyelets of the power circuit and those of the telecommunications circuit on the printed circuit board are to be large enough to guarantee the values required by VDE regulations for increased test voltage. This object is achieved according to the invention by providing the protective cap with an intermediate wall which engages in a slot of the printed circuit board located between the power circuit and the telecommunications circuit.
