Title: Method for measuring and making visible UV rays
Inventor: BRUECK GERNOT K PROF DIPL PHYS
IPC: G01J1/58
Filed: 1993-02-12
Abstract: For measuring and making visible invisible ultraviolet light rays with the aid of photoluminescent substances (2), it is proposed to arrange fluorescent materials (2) of this type on the surface or in a UV-transparent film (1) made of fluorocarbon polymer, to subject this system to UV irradiation and to feed the visible light generated by the fluorescent materials (2) to a light-sensitive measuring element. In this way it becomes possible to displace the UV light into the visible range and to measure it with the aid of commercially available photosensors for visible light. At the same time, an exceptionally cost-effective night-vision device can be provided by means of the method. In a preferred application of the method, the UV light to be measured enters into the interior (20) of a hollow sphere (15), which has a high-gloss-polished inner surface (16) with a coating of fluorocarbon polymer (12), in which fluorescent pigments (2) are contained. Incident UV light is converted into visible light in the interior of the hollow sphere (15), the UV radiation being partially absorbed but partially scattered. Because of the fluorescent pigments preferably used, a uniform illumination results in the interior of the hollow sphere (15), so that the UV light converted into visible light can be measured using a commercially available photosensor (24). <IMAGE>

Title: Microcuvette system and use thereof in absorption photometry
Inventor: MAECHLER MEINRAD
IPC: G01N21/552
Filed: 1993-03-15
Abstract: A microcuvette system for absorption photometry contains a cylindrical cuvette tube (1) having a hollow core for holding a sample liquid (2) through which radiation is passed at least in a longitudinal part of the hollow core, the absorption of which radiation is subsequently measured. The cuvette tube (1) and the sample liquid (2) are coordinated in terms of refractive index so that they act as a stepped waveguide for the radiation, in which waveguide the sample fluid (2) forms the core and the wall of the cuvette tube (2) forms the cladding, so that the radiation undergoes multiple reflection, preferably multiple total internal reflection, at the outer wall of the cuvette tube (1) and the radiation passes through the sample fluid many times. <IMAGE>

Title: Hydrodynamic vehicle retarder with low residual drag - has profiled scoop-wheel rotor and stator with additional peripheral stator ports to augment fluid venting when disengaged
Inventor: VOGELSANG KLAUS
IPC: B60T1/087
Filed: 1993-04-06
Abstract: The hydrodynamic retarder has a drive shaft to which is attached a profiled scoop wheel rotor (2) which rotates in close proximity to a fixed stator (3) having scoop chambers similar to the rotor (2). The rotor (2) and stator (3) are enclosed by a housing (4) and the scoops together make up a toroidal torque-dissipating space (10). An additional unit supplies hydraulic fluid for torque control to the space (10) via the inlet ports (5,6) and the slots (8) in the rotor (2) and the fluid is vented after retardation at the outlet port (7) via the slots (9) augmented by the slots (11) in the stator periphery. USE/ADVANTAGE - Ensures rapid venting of torque chambers when disengaged with minimal residual drag due to air turbulence/unexpelled fluid. High speed running when disengaged does not produce excessive temp. rise due to optimal profiling of scoops.

Title: Determn of catecholamine in biological sample - by inducing fluorescence then analysing using chromatography, with addn of maleimide to prevent interference
Inventor: YASUDA KENJI
IPC: G01N33/52
Filed: 1993-10-20
Abstract: Determination of analyte(s) (I) selected from catecholamines and/or their metabolites in a biological sample comprises inducing fluorescence in (I), after pretreatment, using a fluorescence inducing reagent (II). The fluorescent prod. is then separated by liq. chromatography and analysed. The novelty is that a predetermined amt. of maleimide (III) is added before the sample is rendered fluorescent. Alternatively, (i) in the pretreatment step the sample is added to a sample vessel to which a predetermined amt. of (III) has been added and mixed with a solvent; (ii) (III) in solid form and a solvent for (III) are prepd. separately then mixed before the sample is rendered fluorescent; or (iii) (III) is added during prepn. of the sample for fluorescence induction. Appts. for the determn. is claimed, comprising a device for delivery of a predetermined amt. of sample, connected to a pretreatment device; appts. for contacting the pretreated sample with (II); a chromatography column for adsorption and sepn. of the fluorescent prod.; and a fluorescent intensity detector; where a predetermined amt. of (III) is supplied to the sample delivery device or the pretreatment device. Pref. a processor is included, to calculate, store and display the fluorescent intensity. Also claimed is a reagent for the determn., including solid (III) and a solvent for (III), which are mixed before use. USE/ADVANTAGE - The process is used e.g. for determn. of very low concns. of norepinephrine, epinephrine or dopamine in urine, blood or spinal fluid. Addn. of (III) prevents other components of the sample from interfering with the fluorescent peaks of (I). (III) reacts with thiol cpds. and aminoacids in body fluids, preventing these cpds. from reacting with (II). More accurate results are then obtd.

The thickness of the inner walls (10) gradually increase in a linear manner as from the radial inner side to the radial outer side. USE/ADVANTAGE - The unit is an extruded honeycomb structure made of a material such as ceramics or plastic. A fluid passing through the passages has a uniform velocity as it flows through the passages. Further, the catalytic efficiency of a catalytic converter made of such a honeycomb is enhanced.
Patent DE-4400510-A1 (DE)
Title: Container, in particular drug container
Inventor: MAASER ARNFRIED
IPC: A61J1/20
Filed: 1994-01-12
Abstract: The invention relates to a container, preferably to a drug container, for the sterile mixing of drugs consisting of two or more components.   The container is designed such that further containers are located inside the container, the further containers housing the different components separately. Using an injection cannula which is initially introduced into the outer container and then consecutively into the inner containers (ampoules), the mixing procedure principally takes place by the conventional method and the drug is subsequently drawn into the syringe. The opening of the outer container through which the cannula is introduced is filled by a type of silicone plug which ensures that the interior of the outer container remains sterile even after introduction and removal of the injection cannula. Since handling is practical, the time expenditure is in no way higher than before, and in fact it is rather less, and the risk of injury to the user is likewise less, while storage of an open ampoule in the container is unproblematical because the interior is sterile and - and this is probably the most significant advantage - infectious diseases caused by non-sterile medicaments can thus be avoided. Various embodiments of the container according to the invention permit its application in many medical fields. <IMAGE>

Title: Integrated semiconductor circuit and method for testing the same
Inventor: KITAGUCHI AKIRA
IPC: G01R31/28
Filed: 1994-02-11
Abstract: An integrated semiconductor circuit is disclosed which can be tested with a high speed clock at normal operating level or higher, which is used even in the case of a relatively inexpensive IC tester which cannot deliver the high speed clock pulses, and a method for testing the same. An exclusive-OR gate (2) of the integrated semiconductor circuit receives the first test-clock pulse (TCLK1) via the first test-clock pulse input terminal (P1) in the first input and the second test-clock pulse (TCLK2) via the second test-clock pulse input terminal (P2) in the second input in order to output a high speed clock (SCLK) which results from the test-clock pulse, at an A input of a selector (3). In this way, the integrated semiconductor circuit internally generates the high speed clock at a higher frequency than the test clock for driving the internal circuit, as a result of which it is tested when using the relatively inexpensive IC tester at a clock frequency at normal operating level or higher. <IMAGE>
Patent DE-4405766-A1 (DE)
Title: Transmitting, processing and/or storing digital colour TV signal
Inventor: SEELIGER ROLF
IPC: H04N11/04
Filed: 1994-02-23
Abstract: The digital colour TV signal consists of a digital luminance signal, Y, and two colour difference signals, U,V. Under normal conditions, a standard quantity of data is transmitted for the luminance signal, and standard quantities of data for the colour difference signals. If the amplitude of the luminance signal falls below a selectable value, the quantity of luminance data in the signal is reduced, e.g. by decreasing the word size, and the quantities of colour difference data are increased, e.g. by increasing the word size. This prevents lack of definition in the colour signal from becoming noticeable in pictures of low brightness.

Title: Digitally modulated data signal DC-free transmission method in e.g. magnetic storage
Inventor: LOEW ANDREAS
IPC: G11B20/14
Filed: 1994-08-27
Abstract: The method involves including, in the signal, a train of code words, whose transit length is limited to that of symbols (1,7).  The code signal is delayed for a duration of n bits, where n is an integer greater than unity.  From respective blocks of non-delayed and delayed code signal are determined two digital sum variations (DSV1,2). The variations are compared for their signs for generating sign dependent separating words with a given bit pattern.  The separating words are inserted between adjacent blocks.  The code signal is then inverted, based on NRZI coding, in dependence on the respective bit pattern of the separating words.
