Title: Process and apparatus for purifying exhaust gases
Inventor: WETTERMANN HARRY
IPC: B01D53/50
Filed: 1993-07-15
Abstract: In a housing through which granules and admixed sorbent recirculate through a housing from top to bottom, various temperature zones are formed which make possible the dry chemical reactions for desulphurisation, defluorination, denitration and afterburning. Moreover, dedusting takes place in the granules migrating downwards. Thus the measures according to the invention give a multistage purification system for exhaust gases in a single housing using a dry process.

IPC: H03H17/06
Filed: 1994-01-29
Abstract: The non-recursive polyphase filter network has L branches, where the incoming samples are delayed by a delay register chain, and the delayed samples are multiplied by filter coefficients h1,.... hN and the product is summed. A maximum of (N/2) multipliers are used, where (N/2) is the next integral value after N/2 so that, instead of two multipliers to multiply the two values about the centre of the impulse centre of the sequence, where symmetric coefficients are used, only one of these multipliers is used. An adder is used to sum the two values before multiplication. The second input of the adder is connected to the corresp. tap of the delay chain.

IPC: H04L9/08
Filed: 1994-06-04
Abstract: The invention pertains to a device for decryption of digital information and the process for decrypting  this information, wherein the decryption device allows authorized persons access and denies access to unauthorized persons. The aim of the invention is to devise a process with which information can be distributed to more than one receiver in a user-friendly way, with a low technical-admininstrative complexity for the information encryption. This process would also involve a special processor that performs the decryption reliably and economically and that guarantees key analysis and protection of the decryption algorithm. With reference to the figure, the aim is achieved by the decryption device which consists of an integrated circuit (1) with a central processor (CPU-2), as working memory an internal nonvolatile random access memory (RAM-3) that cannot be read out, an internal nonvolatile random access memory (ROM-4) that cannot be read out and interface (5), with an external nonvolatile random access memory (ROM-6) effectively working with the integrated circuit (1) so that a data path (a) links the latter with the central processor (CPU-2), the interface (5) being situated between the central processor (CPU-2) and the personal computer (7), which are linked with data path (b), each decryption device differing from the others by the contents of the external memory (ROM-6) and/or that of the internal memory (ROM-4) and being partly integrated in an integrated circuit.

Title: Process and apparatus for enriching and purifying aqueous hydrogen peroxide solutions
Inventor: SHIMOKAWA SHIGEKI
IPC: C01B15/013
Filed: 1994-09-12
Abstract: The invention relates to a process and an apparatus for producing enriched, purified aqueous hydrogen peroxide solutions, by means of which it is possible to obtain high-purity hydrogen peroxide solutions which are also suitable, in particular, for use in the electronics industry. The apparatus comprises:   (I) a vaporisation device (2) for vaporising the crude hydrogen peroxide solutions to give vapours containing liquid in the form of a liquid mist, (II) a gas-liquid separation device (4) for separating the vapours from the liquid mist and (III) a distillation column (6) for the fractional distillation of the vapours freed of the liquid mist. It is characterised in that the gas-liquid separation device (4) comprises at least two and preferably two or three cyclones (26, 28, 30) connected in series. The connection in series of the cyclones (26, 28, 30) gives a highly effective separation of the liquid mist from the vapours which are then concentrated by being subjected to the fractional distillation. Even if only two cyclones are used, the concept of the invention leads to high-purity H2O2 solutions of a quality which was not obtainable according to the prior art, since the H2O2 solutions have considerably reduced contents of impurities. <IMAGE>

Patent DE-4441874-A1 (DE)
Inventor: HECHT HANS DIPL PHYS
IPC: G01F1/68
Filed: 1994-11-24
Abstract: Known devices for measuring the mass of a flowing medium have a temperature-dependent measuring component which is housed in a measuring channel and around which the flowing medium flows. In a turbulent flow, unstable separation occurring in the measuring channel causes so-called background noise of the measuring signal emitted by the measuring component so that accurate measurement is difficult. The device according to the invention comprises, upstream of the measuring component (20) in the region of an inlet opening (36) in the measuring channel (33), a flow obstacle (50) taking the form of a trip edge (51) in order to generate in the region thereof a temporally and spatially stable separation area (54) such that temporally and spatially unstable separation areas are prevented. In this way the measuring signal background noise can be reduced. The invention is used for measuring the mass of a flowing medium, in particular for measuring the intake air mass of internal combustion engines.

Title: Ring-spinning machine extended draw-work which excludes torque fluctuation
Inventor: WOLF HORST
IPC: D01H1/22
Filed: 1994-12-30
Abstract: In a spinning machine, esp. a ring-spinning machine, there are draw-works (31) having two, pref. three lower cylinders (11,12,13) placed one after the other, working in conjunction with upper rollers and extending over a large number of spinning stations (14). To reduce torsion the cylinders are driven from both ends and at least one pref. the middle (12) is driven by a rotating field magnet (15). Between the magnet and its driven cylinder end (16) is interposed a gear drive, esp. a helical gear (17) with a large step-down ratio to greatly reduce the magnet rotation speed. This arrangement makes it impossible for torque transmission in the reverse direction, i.e. from the lower cylinder to the magnet.

Abstract: A disk brake with a caliper (2) that contacts a disk (1) has on one side an application device. The application device has a cam lever (4) rotatable around an axis parallel to the brake disk plane and which preferably cooperates by means of a tie-bar (6) with one or two adjusting spindles (7, 8) against which a brake lining (10) is supported. The two adjusting spindles (7 and 8) are coupled by a toothed belt (12).
