Patent DE-3815540-A1 (DE)
Inventor: KRAMER ROLF
IPC: B61G5/02
Filed: 1988-05-06
Abstract: The invention relates to a hinged connection, in particular for multiple-unit rail vehicles in which at least one vehicle part is equipped with at least two running gears, each further vehicle part being supported on this vehicle part or on a further vehicle part and the hinged connection permitting horizontal and vertical deflection movements of the vehicle parts with respect to one another. The large constructional height of the lower coupling which impedes the construction of a lower floor level as well as unfavourable segment-like loading of the rings of the ball live ring and the necessity of an upper support between the carriage bodies are disadvantageous in the previously known embodiments. The object of the invention consists in constructing the hinged connection in such a way that an extremely low constructional height is achieved and the upper coupling between the adjacent ends of the carriage bodies can be dispensed with. This object is achieved in that a levering (5) which can be rotated about a vertical axis and has an outer and an inner ring (5a and 5b) is arranged between the vehicle parts (1 and 2), one ring (5a or 5b) of the levering (5) being connected to the one vehicle part (1 or 2) in a flexurally and torsionally flexible manner and the other ring (5b or 5a) of the levering (5) being connected to the other vehicle part (2 or 1) in a torsionally rigid manner by means of a horizontal joint (9). <IMAGE>

Title: Process for operating heating installation, and heating installation
Inventor: GUIDON WILLI
IPC: F24D19/10
Filed: 1988-06-15
Abstract: The heating installation contains a heating boiler having a burner and a heat-discharge system which is connected to the heating boiler via flow and a return. A regulating means with temperature sensors for the external temperature TA and the heating-boiler temperature TK controls the heating installation. In order to improve the heating installation, the regulating means contains a switching member which switches over the regulating means into an operating range B1 or B2. The first operating range B1 lies above a heating-boiler minimum temperature TKmin and requires a switching-temperature value S1 equal to a constant temperature value  DELTA Tkon. In the operating range B2 beneath the heating-boiler minimum temperature TKmin the switching-temperature value S2 is made up of the constant temperature value  DELTA Tkon and a variable temperature value  DELTA Tvar, which corresponds to the difference between heating-boiler minimum temperature TKmin and the heating curve KH. <IMAGE>

Title: Signal processing method for propagation-time (delay-time) difference measurement in a hyperbolic position-finding system
Inventor: HISSEN HELMUT DR ING
IPC: G01S5/06
Filed: 1988-07-06
Abstract: In the case of hyperbolic position-finding systems (navigation systems) having a plurality of spatially separated receiving stations, the received signal sections which are received synchronously by the receiving stations during a predetermined measurement time and are transmitted to the evaluation point are cross-correlated in pairs in a common evaluation point. If digitised received signals are present, the maximum of the cross-correlation function (KKF) is normally between two time-discrete values of the cross-correlation function, so that said values must be interpolated for precise determination of the position of the correlation maximum. For low-cost interpolation it is proposed to convert a section of the cross-correlation function for a first coarse interpolation by means of a fast Fourier transformation (FFT) into a spectrum and to extend said spectrum considerably, all the values in the extended part being set to 0, and the extended spectrum being transformed back, by means of an inverse fast Fourier transform, into a further cross-correlation function having a considerably smaller increment width. The maximum value of the further cross-correlation function and the immediately adjacent values are used as the basis for parabolic interpolation for precise determination of the maximum of the cross-correlation function, and thus for determining an estimated value for the desired propagation-time difference.
Patent DE-3825111-A1 (DE)
Inventor: HOHENSTEIN NORBERT
IPC: G01D5/243
Filed: 1988-07-23
Abstract: An impedance which can be influenced by a physical measurement quantity, for example a sensing capacitor for humidity measurement, is part of a freely oscillating harmonic HF oscillator, the resonant frequency and damping of which are to be determined. For this purpose, constant-frequency HF excitation pulses are applied to the oscillator. The resonant frequency of the oscillator is detected by counting the free oscillations between two excitation pulses. The damping is detected by sampling the envelope curve of the free oscillations, which are rectified, in particular, by a ring mixer, at at least two defined times between two excitation pulses. <IMAGE>

Title: Method of increasing the critical current density in metal-sheathed high-temperature superconductors
Inventor: SZULCZYK ANDREAS DIPL ING
IPC: H01L39/24
Filed: 1988-10-15
Abstract: In the forming (shaping) of the composite conductor required in the production of metal-sheathed high-temperature superconductors from ceramic materials (composite conductors) the superconducting properties of the conductor are at least partially lost. The superconducting properties can be restored by means of a subsequent heat treatment under oxygen in the temperature range of the orthorhombic phase. It has surprisingly been found that a targeted heat treatment in the temperature range of the tetragonal phase, preferably between 880 and 900@C, in vacuo or under a protective gas atmosphere, which is carried out before the oxygen aftertreatment, increases the critical current density.

Inventor: CHRISTOPHER AMY SUE
IPC: B41J29/38
Filed: 1989-06-16
Abstract: A printer having a number of optional features or operations is reconfigurable by software alone. The printer includes an EPROM (200, 202) that stores the software routines defining all of the optional operations of the printer. An EEPROM stores a jump table (Fig. 7) identifying each optional operation software routine as enabled or disabled. The information stored in the jump table for each enabled routine identifies the location at which the routine is stored in the EPROM; whereas, the information stored for each disabled routine includes a disable flag. An interface (252) allows a new jump table to be downloaded from a personal computer (212) into the EEPROM to enable disabled routines, to disable enabled routines, and to replace disabled routines by downloading a new routine into RAM (204, 206) to thereby reconfigure the printer. <IMAGE>

Filed: 1990-01-10
Abstract: Energy ray ablation is carried out with a pulsed photon ray, esp. laser ray, operating on a restricted area of a workpiece (I). (I) contains an ablation-promoting dopant (II), which absorbs the ray much more strongly than the actual material of (I). The novelty is that (II) is decomposed into a gaseous component (III) of relatively small mol. wt. by the absorption of one photon. Pref. (III) includes a permanent gas and pref. consists mainly of di- or tri-atomic mols. (II) is diphenyltriazene (DPT) or 9,10-dihydroanthracene -9,10-dicarboxylic anhydride (DADA) and/or 1,4,5,6-tetrachloro-7-phenyl -bicyclo-2,2,2-oct-5-en -2,3-dione (TPBD); and (I) consists of plastics, e.g. PMMA. USE/ADVANTAGE - The deg. of ablation is increased and the use of (II) giving gaseous (III) makes ablation more effective and cleaner. The process is efficient and gives sharp edges without marked thermal stress, even at relatively long wavelengths.
