Title: Method and device for contactless temperature measurement
Inventor: ZIMMERHACKL MANFRED DIPL ING D
IPC: G01J5/00
Filed: 1981-12-14
Abstract: The invention relates to a method and a device for carrying out contactless temperature measurements which are independent of the degree of emission on the basis of radiation pyrometry, the invention being applied in all branches of the economy. The aim of the invention is to enable use both in the high-temperature range and in the low-temperature range, a minimum of preconditions and preliminary information being required. The object consists in enabling a true determination of object temperature even given imprecise knowledge and/or a varying degree of emission. The essence of the invention consists in that a pyrometric arrangement which is sensitive in a plurality of spectral regions is used for the sequential detection as input variables of the band signals of the radiation of the measured object without and with auxiliary radiation of a known spectral composition which is reflected at the surface of the measured object, and to input said variables into a computer. The computer combines the input variables in such a way that the unknown variables, such as true object temperature and degree of spectral emission are determined by iterative solution of a system of nonlinear equations.
Patent DE-3152020-A1 (DE)
Title: Image generating device for producing coloured images of any size
Inventor: HACHT GERHARD VON DIPL ING
IPC: H04N9/31
Filed: 1981-12-31
Abstract: The so-called shadow-mask or slotted shadow-mask picture tubes are used for colour television. The spatial path of the electron beams in the shadow-mask picture tubes requires additional devices to a considerable extent. These additional devices make the production of shadow mask picture tubes technically complex and relatively expensive. In the image generating device according to the invention for displaying coloured images of any size, the light from three or more laser diodes in the three conventional basic colours of blue, green and red and possibly others, is directed into thin flexible optical waveguide tubes combined to form one optical waveguide tube bundle. The optical waveguide tubes are clamped in a clamping holder at the ends facing the laser diodes and are provided with a magnetisable sheathing at the other end. The magnetisable sheathing is surrounded by horizontal and vertical yoke magnets which have deflection coils for controlling the light in all four directions. The light emanating from the optical waveguide tubes falls through projection optics and is then directed by one or more deflection mirrors, following one another, onto the ground glass screen which is free of luminescent material or coated with luminescent materials, at least in the three basic colours of blue, green and red. Thus, the invention makes it technically much simpler and more inexpensive to produce image generating devices for displaying coloured images of any size.
Patent DE-3201655-A1 (DE)
Title: Circuit for equalisers
Inventor: LEUNIG PETER
IPC: H04H60/04
Filed: 1982-01-21
Abstract: The circuit is used in equalisers whose sections can be digitally controlled by a computer, in particular in studio systems. The circuit is characterised by one or more of the following features: opto-fets serve as switching elements; combinatorially connected networks are used to control the frequency and amplitude parameters; a part of the output signal of the amplitude regulator is returned to the input of the latter; and the amplification-defining network is used for both emphasis and de-emphasis. In the equaliser, transmission quality is retained, unlike conventional, manually controllable equalisers. Feedover of the digital control signal onto the electro-acoustic path lies below the audible threshold. The emphasis/de-emphasis amplitude occurs in exponential steps. The emphasis curves are mirror-symmetrical with the de-emphasis curves.
Patent DE-3204424-A1 (DE)
Title: Electrical apparatus
Inventor: SCHALLER WERNER DIPL ING
IPC: H02G3/08
Filed: 1982-02-09
Abstract: The invention relates to an electrical apparatus and to a method for producing the apparatus with the connecting lines inserted such that they are protected against the ingress of moisture. A device (5, 14) is used for this purpose which is held on the apparatus, clamps a cable or line connecting end (4) and produces a seal between the outside of the cable jacket (9) and the apparatus itself. In order to achieve the seal between the individual cores (16) and the insulation (17) of the individual cores and the cable jacket (9), such a quantity of solvents which dissolve the individual cores or their insulation are applied before the clamping process, preferably from the apparatus side, that a slight deformation in the region of the clamping is produced in order to form a common seal which cures after the deformation, without in this case having to reduce the insulation between the individual cores in an unacceptable manner. <IMAGE>

Title: Device for checking the directionally accurate guidance of a surgical tool
Inventor: KLUGER PATRICK DR MED
IPC: A61B17/15
Filed: 1982-02-16
Abstract: In some surgical interventions the required working direction of an instrument cannot be fixed on external structures but only by axial representation with an X-ray device, that is, the surgical tool must be aligned toward the beam path of the X-ray device. One example of this is, inter alia, the locking, remote from the body of an intramedullary pin. The invention relates to a device which displays on the screen of an X-ray amplification chain outside the target cover formed by the surgical tool whether the working direction of the tool coincides with the X-ray direction determining the required working direction. This object is achieved in that the device fastened on the surgical tool comprises X-ray contrast sight marks (1) which are radially aligned toward the axis of the working direction (2) of the surgical tool and are arranged in two levels (3) consecutively coinciding with each other in the working direction. The drawing is a diagrammatic representation of the arrangement. Any tilting of the actual working direction as compared to the required working direction of the tool is evident by the double imaging of the sight marks on the screen of the X-ray amplification chain. <IMAGE>

Title: Spring force drive for an electrical switch
Inventor: PEITZ THEO
IPC: H01H3/30
Filed: 1982-09-09
Abstract: A spring force drive for an electrical high-voltage switch has a switch-on spring (38) which drives the switch shaft (10) and hence the switch contacts of the high-voltage switch during switching on and a switch-off spring (48) which drives the switch shaft (10) during the switching-off process. The switching on spring and the switching off spring have allocated to them a first and second interlock respectively, which respectively fix the two springs in the tensioned state and release them during the switching on and switching off processes respectively. Two levers (28,30) are supported rotatably, with respect to the shaft and to one another, on the switch shaft (10), one of which levers is connected to the switch-on spring (38) and the other to the switch-off spring (48). Furthermore, a driver (14,16) is rigidly coupled to the switch shaft (10) and, in the case of a switch operation, the levers engage with the driver in such a manner that, on switching on, after unlocking the first interlock (60) of the switch-on spring, the tensioned switch-on spring is released so that the lever (28) operates the switch shaft via the driver, and such that, during switching off, after unlocking the interlock (76) of the switch-off spring, the tensioned switch-off spring is released, so that the lever (30) operates the switch shaft, likewise in the switch-off direction, via the driver. <IMAGE>

Title: Invertor circuit
Inventor: ROLLE SVEN ING GRAD
IPC: H02M7/5387
Filed: 1982-09-15
Abstract: In an invertor circuit in which two power field-effect transistor switches, which are connected in series and conduct in reverse, are connected to a DC voltage source and the load is connected between the junction point of the two transistors and the two poles of the DC voltage source, the slow transition of the integrated inverse diodes, which are present in the field-effect transistors, from the conducting mode to the blocking mode is a disturbing factor. For this reason, fast, discrete diodes (D1, D2) with very good low characteristic forward values, i.e. threshold voltage and equivalent resistance, are connected in parallel with the source-drain junctions of the field-effect transistors (T1, T2), the conducting-state voltage of the fast additional diodes (D1, D2) not reaching the threshold voltage of the integrated (parasitic) inverse diodes (DT1, DT2) of the field-effect transistors (T1, T2). The integrated inverse diodes (DT1, DT2) do not then participate in the current supply. <IMAGE>

Patent DE-3304005-A1 (DE)
Title: Centrifugal therapy device
Inventor: KELP HANS HEINZ DR
IPC: A61H1/00
Filed: 1983-02-03
Abstract: Centrifugal therapy device for application on the human body. Centrifugal therapy is especially intended for patients with spinal disorders in whom stretching of the spine is of therapeutic benefit (alleviation of pain, curative effect). These include, in particular, disc disorders with nerve compression syndromes. Stretching of the spine can reduce or eliminate the nerve compression. The device comprises a plate or a bar cross with a support facility for the patient. A motor sets the system into a rotating movement. The number of revolutions per minute can be adjusted. The patients are supported radially with the feet pointing outward, either individually with a counter-weight or in pairs lying opposite each other. In the case of fixing on the head, shoulders or chest the patients are supported on sliding special plates in such a way that spinal sections which are not to be treated move centrifugally en bloc when the centrifugal force commences, as a result of which a special stretching effect is imparted on those spinal sections which are to be treated and which do not lie on sliding plates. This results in immediate freedom from pain in vertebragenic nerve compression syndromes.
