Patent DE-3033226-A1 (DE)
Title: Pulse compression filter for single-double sideband data transmission - uses filter coefficients derived from bit values of time inverse sequence
Inventor: SEIDLER PETER DR ING
IPC: H04L1/24
Filed: 1980-09-04
Abstract: The pulse compression filter is used with test pulse sequences carried out in order to operate a single sideband or double sideband data transmission process with suppressed carrier. It is used in media with linear distortion and frequency shift as a result of the Doppler effect. The data are transmitted in the form of data blocks preceded by the test pulse sequence. The test pulse sequence is used to effect correction to the filter parameters and to continuously compensate the frequency in two orthogonal channels. The filter coefficients of the compression filter are equal to zero. They are derived from the bit values of the time inverse sequence associated with the pseudo noise sequence. A positive value of the time invese sequence produces a finite filter coefficient and a negative one produces a zero filter coefficient.

Title: Electron beam welding machine - with adjustable intermediate lens reducing aperture angle for same high directivity
Inventor: JUCKER JAN DR ING
IPC: B23K15/02
Filed: 1980-10-02
Abstract: Electron beam welding machine has an electron gun with a Wehnelt electrode between the cathode and the tubular anode. It produces a beam of high directivity and a large aperture angle which passes through an intermediate lens in the anode mount. This lens is set to focus the beam to a smaller divergent aperture angle and is followed by adjusting coils. The cut-off frequency for the magnetic reversal of the intermediate lens is at least 500 Hz. The high directivity results in a better weld penetration, i.e. a very deep and very narrow seam over a wide working range.

Title: Finger-print comparator using photodetector - detects coincidence between reference print and moving projection of actual print
IPC: G07C9/00
Filed: 1980-11-28
Abstract: The finger-print is applied to the sloping face of a prism. The finger-print is projected optically through a reference finger-print (1) on a transparent plate. Coincidence between the projected finger-print and the reference finger-print causes a first electrical output at a photodetector (12) whilst noncoincidence causes a second output. The image of the finger- print on the prism passes through a device (9) that causes it to move continuously in a given manner (e.g. in a spiral) in a given plane such that it moves in the same manner over the reference finger-print. If the finger-prints are identical the light incident on the photodetector will be greater than if they are not identical. The comparator can be used for comparing a finger-print on a security card with the user's actual finger-print in order to gain access to a building. The comparator can also be used to compare patterns other than finger-prints.

Title: Device for converting thermal energy into electrical or mechanical energy by means of a magnetic system
Inventor: BRUNGSBERG HEINRICH J
IPC: H02N10/00
Filed: 1981-02-21
Abstract: The widespread efforts for direct conversion of thermal energy into electrical energy have had no major success until now. The operating principle of the present invention is based on the property of ferromagnetic materials that they change their magnetic behaviour as a function of the temperature. Magnetic fluxes can thus be controlled and energies transmitted in suitable magnetic circuits. The results of previous proposals were unsatisfactory because of the slow changes in the magnetic fluxes. The characteristic feature of the invention is a system which makes possible rapid flux changes. This is done on the one hand by the construction of the part which can be influenced thermally in the magnetic circuit as a regenerator with a very small time constant and, furthermore, by the supply and extraction of the active heat to and from the regenerator via a compressed gas as the heat carrier. Excited by a control part, this gas oscillates in time with the operating frequency between two containers whose temperatures are below and above the Curie point of the magnetic material which can be influenced thermally. Sources for the magnetic flux are permanent magnets with a high specific energy content.

Title: Front panel for an electronic assembly
Inventor: EISENREICH GUENTER
IPC: H05K7/14
Filed: 1981-03-11
Abstract: The invention relates to a front panel for an electronic assembly for pushing into a mounting rack, in the case of which plug connectors and attachment elements are arranged in a grid having a grid size (M). The front panel (1) has at least one projection (2) with two opposite attachment surfaces (2a, 2b) to which a printed-circuit board (3) can optionally be attached. The distance (A) between the attachment surfaces (2a, 2b) is equal to an integer multiple of the grid size (M) less the thickness (C) of that part of the printed-circuit board (3) which is resting on the attachment surface (2a, 2b). A different distance to the adjacent assembly results as a function of the attachment surface (2a or 2b) to which the printed-circuit board (3) is attached. The maximum permissible voltage on the printed-circuit board (3) is governed by this distance. The front panel described can thus be used in a common manner for printed-circuit boards (3) carrying high voltage and low voltage. The distance between the attachment surfaces (2a, 2b) is in this case selected such that it always results in insertion in the predetermined grid of the mounting rack. <IMAGE>

Patent DE-3212644-A1 (DE)
Title: Foot support and method for production thereof
Inventor: VATTER PETER
IPC: A43B7/22
Filed: 1982-04-05
Abstract: In foot supports having a rigid supporting core (SK) and soft surface layers (BO, BU) which project beyond the front edge (VKK) of the supporting core and form a pliable edge region (VR), there is the problem of obtaining a soft transition of the flexural strength between the supporting core and the edge region, as well as the problem of obtaining maximally soft transitions of the flexural strength between the areas of the supporting core having different thicknesses. To solve these problems, a thin, elastic, dimensionally stable and pliable support layer (SS) is integrally formed, so as to be shear-resistant, at the lower and/or upper side (OFL, OF2) of the supporting core (SK), preferably with insertion of porous transition layers (US). In the transition region (UB) between the supporting core and the edge region, this results in a larger sweep and a gradual change in flexural strength. The supporting core is preferably designed as a homogeneous, plastic body capable of fluxural deformation. <IMAGE>
