Abstract: 1. Method for demodulating a FSK signal with signal elements (bits) of constant element length (T) and in each case one of several predetermined frequencies (omega i ) according to the correlation method, in which for correlating the filtered, digitized incoming signal (A) is multiplied pairwise with periodic, orthogonal correlation signals (Bi , Ci ) of the predetermined frequencies (omega i ), the multiplication signals (A . Bi , A . Ci ) are integrated, sign-independent integration values (¦ SABi ¦, ¦ SACi ¦), these values are combined pairwise and the sums of these values are compared with one another for forming the demodulation signal (Y) to be emitted, characterized in that each multiplication signal (A . Bi , A . Ci ) is continuously supplied on the one hand in undelayed form and on the other with the reverse sign delayed by one element length (T) to an associated integrator (44 to 47), that continuously a decision signal (X) is emitted, whose signal value (xi ) is associated with the largest of the sums, that the particular signal value (yi ) of the demodulation signal (Y) is in each case retained for as long as the mean standing time (ri ) of the signal value (xi ) of the decision signal (X) associated with said signal value (yi ) is higher than the mean standing times (rj ) of all the other signal values (xj ) of the decision signal (X) averaged during the same time period (t), that the signal value (yi ) of the demodulation signal (Y) is modified, as soon as the average standing time (rj ) of one of the other signal values (xj ) of the decision signal (X) is higher than the means standing time (ri ), averaged in the same time period (t), of the signal value (xi ) of the decision signal (X), which was associated with the previous signal (yi ) of the demodulation signal (Y) and the new signal value (yj ) of the demodulation signal (Y) is that corresponding to one of the other signal values (xj ) of the decision signal (X) (i = 1, 2, 3 ...; j = 1, 2, 3 ...; j Not= i).

Abstract: The switching mat consists of two, facing, electrically conductive contact surfaces (1, 2) which are movable the one against the other. Between these are contact windows (4) in electrically-insulated buffer elements (3) the latter being perpendicular to the contact surfaces and elastically ductible. In the area of the contact windows (4), jutting contact nobs (5) are provided on at least one of the two contact surfaces (1, 2), with the distance between contact nobs (5) and the opposite contact surfaces (1, 2) (or the opposite contact nobs) when the switching mat is not charged being not greater than the elastic spring stroke of the buffer elements (3). The contact nobs (5) can be formed of bulges in a film forming one of the contact surfaces (1, 2). To produce the bulges, a difference in pressure is built up between the inside and outside of the switching mat after the sides of both contact surfaces (1, 2) have been sealed, so that bulges are formed in the area of the contact windows (4) on the inside. The bulges are fixed by means of a hardening layer of sufficient form rigidity applied to the outside.

Abstract: A microscope using deconvolution is described, in which the light distribution in the double cone formed by the light is modulated. The modulation is performed in the spatial domain, which distinguishes the system from modulation in the temporal domain such as is known in telecommunications engineering. Optical radiation is modulated by inserting into one of the planes of the microscope a modulating pattern in which the radiation source is sharply imaged. The modulated light traverses the further elements of the beam path and finally impinges on a television camera. The output signal of the television camera is fed to a computer. As an example, 64 sequential object positions are recorded in 64 different focal planes and transmitted as digitised images to the computer, where they are stored and deconvoluted, use being made of an algorithm which takes account of the presence and absence of light in the various regions of the double cone. In order to adapt the algorithm to the modulation pattern employed, a matrix of data is recorded which reproduces the three- dimensional pulsed response of the microscope by means of the modulation pattern. This is performed by Fourier transformation or any other convolution algorithm. This data matrix takes account of the properties of the optics of the microscope, and is transformed into improved images by a convolution algorithm. These images have a superior 3D-resolution, which cannot be achieved at the same speed using other methods. <IMAGE>

Abstract: A vehicle multiplex system includes a multiplex controller (30) mounted in a fuse block (14) of the vehicle (10). Both power buses (22) and control buses (CB1-CB6) radiate from the fuse block (14), and the control buses (CB1-CB6) interconnect the controller (30) with respective input and output units (36, 38) distributed about the vehicle (10). Preferably, the controller (30) selects one of the control buses (CB1-CB6) as an active bus at any given time and isolates the remaining control buses (CB1-CB6) both from the active control bus and from the controller (30). In this way, system reliability is improved, and electromagnetic interference is reduced. By positioning the multiplex controller (30) in the fuse block (14), wiring requirements for the multiplex system are simplified and the multiplex system is more readily integrated into the electrical system of the vehicle (10).

Abstract: A process to produce a pipe section of an expandable shaft is described. An inner jacket, an outer jacket and, between them, a middle layer are applied one on top of the other in sandwich design to an inner mould corresponding to the inside diameter of the pipe section, with mould pieces corresponding to openings (15) in the pipe section attached to the inner mould. The inner jacket and the outer jacket consist of synthetic resin-impregnated fibres (1, 2, 4, 5, 10) and the middle layer consists of a honeycomb material. The pipe section is distinguished in particular by light weight and the associated further advantages, in particular with respect to its ease of handling. In order that the necessary openings (15) do not weaken the structure of the carbon fibres (10), the latter are laid around the mould pieces producing the openings (15) and the sandwich structure is subsequently impregnated with the synthetic resin.

Abstract: The invention concerns apparatus for molding thermoplastic tubing having solid annular ribs. The apparatus is of the type where a tubular mold is defined by cooperatively interengaged mold block of a pair of mold assemblies. An annular extrusion orifice for the tube extends into the mold tunnel and tubing is extruded about a mandrel. The invention provides an accumulator chamber in the region of the extrusion nozzle to provide for pressure differences which build up at that point. Thus, the effective volume of the accumulator chamber can compensate for the varying requirement for the thermoplastic material resulting from the varying radial wall thickness.

Abstract: A procedure and means for filtering and homogenizing liquid substances and for automatic cleaning of the filters. In the procedure are utilized an ultrasonic generator (4) connected in conjunction with the filter unit (1; 2) and ultrasonic oscillators (1.11; 2.11) thereto connected, their power and frequency being controlled on the basis of the differential pressure present across the filter units (1; 2), the liquid pressure acting in the filter unit, the liquid flow rate, signals from liquid temperature pick-ups. In order to enhance the cleaning event of the filter elements (1.2; 2.2) taking place with ultrasonics, the filter unit (1; 2) is emptied during the cleaning phase, making use of compressed air conducted into the filter. In order to facilitate the liquid filtering event and to reduce the need of cleaning action with ultrasonics, during normal filtering an ultrasonic power is maintained which is sufficient for homogenizing the liquid. The filter unit (1; 2) furthermore contains one or several cylindrical filter elements (1.2; 2.2).
