Patent DE-4324154-A1 (DE)
Title: Device and method for analysis, with high spatial resolution, of at least one gas component in a gas mixture
Inventor: RIPPEL HARALD DR
IPC: G01N21/3518
Filed: 1993-07-19
Abstract: In the case of the device according to the invention and the method, a receiver apparatus (1) receives a natural emission spectrum (E) of a gas mixture (G). This emission spectrum (E) is split by a beam splitter (2) and filtered via a reference-filter arrangement (5) and a gas-selection filter arrangement (6) and imaged on a first and second 2D sensor field (3, 4). An image of the background is incident on the sensor field (4), while the radiation-wavelength range in which a gas component absorbs is incident on the sensor field (3). The processing instrument (8) processes the image signals of the two sensor fields (3, 4) and determines therefrom the spatial extent of the line integral of the particle quantity (n.L) of at least one gas component (G1, G2) in the gas mixture (G). This extent can be displayed two-dimensionally on a display instrument (9). The invention allows determination of spatial extents of line integrals of partical quantities (n.L) of individual gas components (G1, G2) in the gas mixture (G) by means of so-called two-dimensional differential emission spectroscopy in the shortest time, so that not only the extents of line integrals of partical quantities (n.L) themselves, but also dynamic processes in the gas mixture (G) can be investigated. <IMAGE>

Title: Toothed-belt drive
Inventor: REICHE ARMIN DIPL ING
IPC: F16H19/06
Filed: 1993-08-16
Abstract: In known toothed-belt drives for converting a rotary motion into a translational motion, continuous switching of the drive motor is required to reverse the motion. These solutions are involved since, to change direction, the motor has to be braked, switched and reaccellerated in the other direction of rotation. The new toothed-belt drive is intended to make it possible to convert a unidirectional rotary motion of a rotary drive into a reciprocating motion and to achieve high uniform speeds over the majority of the stroke. A carriage (5) of U-shaped design which is guided parallel to the longitudinal axis of the toothed-belt drive with the toothed-belt lengths (3) and (4) contains a slide (6) which can be moved in the carriage transversely to the longitudinal axis of the toothed-belt drive. Due to the force of the spring (8), a roller (9) attached to the lever (7) presses the slide (6) against the toothed-belt length (4) and the carriage (5). As a result, the carriage moves towards the right. In the reversal positions, the roller (9) runs onto cam elements, the lever (7) thereby being pushed across and a reversal in the direction of motion taking place. The toothed-belt drive permits simple conversion of a unidirectional rotary drive into a reciprocating motion, high, uniform speeds over the majority of the stroke being achievable. <IMAGE>

Title: Method for producing a temperature sensor sheathed with plastic and having a shortened response time
Inventor: HENSCHEL ADOLF
IPC: G01K7/22
Filed: 1993-08-28
Abstract: A method is described for producing a temperature sensor which enables a temperature sensor, for example having a plurality of plug and socket contact pairs, to be produced in one operation. In each case the plug and socket contact pairs, between which at one end the thermistor pellet is arranged, are inserted into an injection mould. Then, in only one operation, the plug flange, the central holding part and the sheath which surrounds the plug and socket contact pairs and the thermistor pellet on the other side are moulded. In this injection moulding process, on the sheath surrounding the thermistor, elevations are moulded on in order to achieve a turbulent flow of the boundary layers of the medium to be measured and thus a shortening of the response time of the temperature sensor.
Patent DE-4329595-A1 (DE)
Title: Process and apparatus for recycling wash or treatment liquids
IPC: C23C22/86
Filed: 1993-09-02
Abstract: A process and an apparatus are specified for recycling wash or treatment liquids, in particular from chromating baths, in which the used liquid, in particular from the chromating bath (32) is evaporated in an evaporator (50) and is then recondensed in a condensation device (66). During this process, the residual ion content, preferably the electrical conductivity, is monitored by means of a device (68) and the condensate obtained at high residual ion content or high electrical conductivity is collected in a first vessel (88), whereas when a preset threshold value is undershot, the condensate is diverted to a second vessel (90). The condensate from the vessel (90) having a low residual ion content can thus advantageously be used to supplement the wash liquid from one of the wash baths (38), while the condensate having high residual ion content from the first vessel (88) can be mixed with residues from the evaporator (50) and at least in part added back to the treatment bath (32). Overall, the service life of the treatment bath (32) is thus considerably extended and the efficiency of washing is improved without an additional desalting unit being necessary for this purpose (Fig. 2). <IMAGE>

Patent DE-4420136-A1 (DE)
Inventor: RUEB WINFRIED
IPC: B60T15/04
Filed: 1994-06-09
Abstract: The invention concerns a hydraulic valve used in particular to ease a spring-loaded brake and which has a housing (10) and an actuator element (40) mounted on the housing and adjustable in two opposite directions. The valve also has an obturator element (14) fitted so that it can move within the housing, a control spring (26) fitted between a mobile support element (27) and the obturator element and a reset spring (25) fitted between the housing and a support element (28). The force in the reset spring can be increased by moving the actuator element in one direction and, when the actuator element moves back in the opposite direction, the reset spring moves the control-spring support element in the direction which increases the force in the control spring. In order to keep the force necessary to operate the brakes low, mechanical force-magnification means (48, 51) are fitted to act between the reset and control springs. The resetting force which the reset spring is required to produce is thus relatively small, thus also making it possible to keep the force necessary to compress the reset spring small.

Abstract: A first measuring value signal is determined by a first measuring tube (1), whose ratio (V) of length (L) to the inside dia (D) is larger than a specified number (1.3), with which the faults can be neglected. A second signal is determined by a second tube (1), the ratio of (V) of length (L) to the inner dia. (D) of which, is smaller than the specified number (1.3), depending on the electrical conductivity of the connecting tubes, under the same conditions as the first signal. A first quotient (Ki) is formed from the first and second value signals. A constant voltage (generator G) is applied at a first pair (3a, 3b) of each second measuring tube (1). Measurement voltages (U1,U2) are tapped from a second pair (4a,4b) and a third pair (5a,5b) of electrodes of each second measuring tube, and in certain cases amplified, amplifier (6). Second quotients (U1/U2) are formed from these voltages (U1,U2). These second quotients are allocated to the first quotients (Ki) in a storage (8). The second quotient (U1,U2)x) is determined in a 3rd measuring tube (10, installed in a use place. The associated 1st quotient (K) is abstracted from the storage (8) across a second quotient (U1/U2)i) corresp. tot he determined second quotient (U1/U2)x). The measuring value signals of the 3rd measuring tube are multiplied with the first quotient (K) as a correction value.
