IPC: G01N21/39
Filed: 1987-12-03
Abstract: In a process and a system for (trace) gas analysis, in particular for NH2 analysis in flue gases from power stations or industrial exhaust gases, a laser is switched to and fro between its two inherent resonance lines, one of the wavelengths corresponding to an absorption maximum and the other wavelength to an absorption minimum of the gas to be detected. The absorbance E and, consequently, the concentration of the gas to be analysed is derived from the ratio of the intensity attenuation at the two wavelengths.

Title: Hydraulic multiple telescopic cylinder
Inventor: KOPPERS MANFRED ING GRAD
IPC: F15B15/16
Filed: 1987-12-24
Abstract: The hydraulic multiple telescopic cylinder has a desired-value transmitter which is composed of a threaded telescope 4 and of a stepping motor 28 and which is coupled mechanically to a valve 27 for the pressure loading of the cylinder space or of the annular space of the multiple telescopic cylinder. The threaded telescope 4 consists of three telescope stages 5, 6', 7 which can be pushed one into the other and which are connected respectively to one another via a threaded connection 9, 10. The threaded connections 9, 10 run in the same direction and are not self-locking and have an identical pitch. The first telescope stage 5 is connected fixedly to the inner piston 23, and the last telescope stage 7 is connected to the valve 27 and to the stepping motor 28 by means of a journal 25. The valve 27 is actuated, that is to say the multiple telescopic cylinder is retracted or extended, depending on the axial position of the journal 25. The threaded telescope 4 converts the rotational movement of the stepping motor 28 into a specific axial deflection which activates the valve 27 in such a way that the multiple telescopic cylinder is correspondingly pressure-loaded until this axial deflection is cancelled again and the stroke position of the multiple telescopic cylinder corresponds to the desired nominal stroke position. <IMAGE>

Title: Root-ball basket for water plants
Inventor: SANDER RUDOLF
IPC: A01G13/02
Filed: 1988-01-07
Abstract: Water plants can be accommodated in an optimally secured manner in aquaria, fish ponds and similar vessels if they are assigned to a root-ball basket, the base and/or side walls of which are assigned one or more sucker-like attachments. Via these sucker-like attachments with their sucker plate, it is possible to fix the entire root-ball basket either on the base of the aquarium or on the side walls such that it is not possible, in particular for the fish, and especially for carp, to move the root-ball basket out of this position. Once the root-ball basket has taken up a position, this can no longer be changed even by current in the aquarium or other eventualities. Moreover, in particular if a corresponding articulation is assigned to the attachment, the root-ball basket, and thus the entire water plant, can be in each case moved into a position in which it has optimum development conditions. <IMAGE>

Title: Clamping device for measuring machines and machine tools
Inventor: WITTE HORST
IPC: B23Q1/52
Filed: 1988-02-17
Abstract: The clamping device for machine tools, which in principle is constructed as described in German Patent 3407003, differs from this clamping device by the basic part 1 being designed as a cylinder circular in cross-section, i.e. as a corresponding column. The surface of the clamping parts 2 which adjoin the circumference of the cylindrical basic part 1 is correspondingly curved. The grooves 4 and rails 3 are likewise curved so that the clamping parts can be displaced, i.e. "rotated", in a continuously variable manner on the basic part in the peripheral direction. In this way, a large number of different and complicated workpieces can be accommodated and machined in one set-up, if need be from five of the six possible sides. In order to provide for reliable and positive-locking restraint in the peripheral direction between clamping part and basic part, a worm-gear tooth system 10 is formed on each cylindrical circumference of the rail 3 of the basic part 1. Furthermore, blind holes 12 are provided at the root of the grooves 4 in each of the opposite side faces 6, running perpendicularly to the grooves and rails 3, 4, of each clamping part 2. The blind holes 12 run tangentially to the circumference and their radius is greater than the distance of the hole axis 13 from the root of the allocated groove. Worms 11 can be inserted into the blind holes from both side faces 6. The worms 11 have at their end faces a receptacle 16 for a tool, and their ... Original abstract incomplete. <IMAGE>

Patent DE-3818418-A1 (DE)
Title: Float flow meter
Inventor: BUSCHMANN HEINZ
IPC: G01F1/22
Filed: 1988-05-31
Abstract: Floats in flow meters were previously guided on a guide rod in the measuring tube, so that a rotation about the axis was possible. In media containing solids, there is a risk of deposits, which impair the free mobility, in the region of the guides. In the case of magnetic transfer of the height position, this led, moreover, to measurment errors, since the transfer magnet connected to the float is often "not round" with respect to the magnetic field, so that a rotation in the measuring tube leads to a variation of the indication without a change in the height position in the measuring tube. The arrangement of a guide slot (8), preferably in a float (25) of open bottom design, in which slot a guide insert (28) engages, has the advantage that no deposits can form in the region of the guides and that the float (25) is guided secured against rotation. <IMAGE>

Title: Thin-film varistor
Inventor: TIZABI DJAMSHID DIPL ING
IPC: C03C17/36
Filed: 1988-08-02
Abstract: Varistors (i.e. voltage-dependent electrical resistors which can be used as triggers in matrix displays) which, at a low voltage (e.g. 3 volts) have a very high resistance (e.g. 10<12> ohms) but at high voltage (e.g. 20 volts) have a low resistance (e.g. 10<5> ohms) may, according to the invention, be fabricated in large numbers on glass wafers in the form of three overlapping vacuum-deposited thin-film patches (sequence aluminium - silicon suboxide - aluminium), the aluminium patches being vapour-deposited in high vacuum (e.g. 10<-7> mbar), the silicon suboxide patches, in contrast, being vapour-deposited "reactively" from silicon in a residual atmosphere, at 10<-5> - 10<-6> mbar, of oxygen or air. Thus it is possible to fabricate, in a highly simplified manner, large-area liquid-crystal point matrix displays.

Patent DE-3830299-A1 (DE)
Title: Method and arrangement for determining internal thermal resistances of wafer-shaped semiconductor components
Inventor: LEIPOLD PHILIPP DIPL ING
IPC: H01L23/34
Filed: 1988-09-07
Abstract: Known methods for determining the internal thermal resistance of semiconductor components require measurement of the housing temperature, as a result of which it is possible to determine different thermal resistances depending on the choice of the type of probe (sensor) and of the measurement location. In order to solve this problem, the invention proposes abandoning direct measurement of the housing temperature and instead performing calculations through an indirect measurement of the depletion layer temperatures via a temperature-dependent parameter, e.g. the forward voltage across a gate cathode junction whose temperature dependence has previously been determined, of two or more semiconductor components, connected back to back, while combining the dissipation flowing through the semiconductor components. The method permits calculation of the thermal resistances on the anode and cathode sides. The method is suitable for all wafer-shaped semiconductor components, and can be applied with particular advantage to components having a structured cathode. The single figure of the drawing applies. <IMAGE>

Patent DE-3831772-A1 (DE)
Inventor: ROTH WERNER DIPL ING
IPC: A47B53/02
Filed: 1988-09-19
Abstract: Rolling shelves comprise several similar shelf elements that can be moved on multiwheel undercarriages on rails (10a, 10b, 11as, 11b) sunk into the floor, opening an access path to the desired element between any two other elements. Both double-axis and double-wheel undercarriages of each shelf element are mirror-symmetrical and run on corresponding offset pairs of rails (10a, 11a or 10b, 11b) of each undercarriage. The four points of contact (4a, 4b, 5a, 5b) between the wheels and the rails form the axially symmetrical corners of a trapezium, the parallel sides of which coincide from the top view with the two wheel axes (12, 13) of the undercarriage. The shelf element moves along the axis of symmetry (19). Two vertical or inclined stays (18a, 18b) that extend from two wheel cases (9a, 9b) maintain the carrying frame in an inclined position which makes it easier to vertically deposit the goods to be stocked and to vertically remove them from the support structures of stocked goods arranged on the carrying frame (15). An open space is created between the carrying frame (15) and the stays (18a, 18b) that extend from the wheel cases (9a, 9b), through which the next shelf element can move with its projection formed by its inclined carrying frame (15) and its attached undercarriages.

Abstract: In order to improve a process for disinfecting water, particularly water from swimming pools, the agent required for the disinfection being obtained as required in an electrolysis apparatus (12) having an anode space (76) and a cathode space (78) and being mixed with the water to be treated, and the electrolysis apparatus being fed with fresh electrolyte, while the spent electrolyte is removed from the electrolysis apparatus and passed into a waste water channel, so that essentially only environmentally acceptable waste water is delivered to the waste water channel, it is proposed that fresh electrolyte is fed to the anode space and cathode space in each case separately and directly as anolyte and catholyte, and that the spent anolyte and the spent catholyte are separately removed from the anode and cathode space. <IMAGE>
Patent DE-3843222-A1 (DE)
Title: Compressed-air weapon
Inventor: ZANNER GEORG
IPC: F41B11/683
Filed: 1988-12-22
Abstract: The compressed-air weapon has a compressed-air cylinder in which a piston is mounted such that it can be displaced longitudinally with the aid of a manually operable cocking lever in order to compress the air. A dropping catch is mounted on the cocking lever such that it can pivot and interacts with the tooth system of a locking bar which is mounted, such that it can be displaced longitudinally, on the cocking lever. During the normal pivoting motion of the cocking lever in the compression direction and in the air-induction direction, the dropping catch is disengaged from the tooth system of the locking bar, which carries out a movement relative to the cocking lever during the pivoting of said cocking lever. However, if the cocking lever is moved in a jerky manner in the air-induction direction, then the dropping catch falls into the tooth system of the locking bar as a result of its inertia, and prevents any further movement of the locking bar and of the cocking lever in the air-induction direction. This effectively prevents the dangerous knocking back of the cocking lever which can occur during the compression process if the hand of the person shooting accidentally slides off the cocking lever.
