Patent DE-4109234-A1 (DE)
Title: Slider ring packing with housing and axially pointing radially inner arm - has compression-spring, support, rubber ring and axial protuberances
Inventor: PESCH KLAUS DIPL ING
IPC: F16J15/36
Filed: 1991-03-21
Abstract: The slide ring packing (1) has a housing (2) with an axially-pointing, radially-inner arm (12). An axially-operating compression spring (3) in the housing has a free end cooperating with a support (5) holding the slide-ring (4) elastically sealed against it. A plate-spring-shaped rubber ring (6), positioned between the support and inner arm, has an axially-pointing protuberance (7) fixed radially as an elastic seal between the slide-ring (4) and the support (5). The rubber ring moves axially on the inner arm of the housing (2). The inner arm runs parallel to the slide-ring's axis (13) near the rubber ring's seating. The end (14) of the inner arm has radial protuberances (15). ADVANTAGE - The slide ring packing exerts an almost even axial force and gives a better seal.

Title: Multiple wood-planing machine equipment - has feeler-operated limit switch stopping tool-slide movement
Inventor: MARTIN OTTO
IPC: B27C1/08
Filed: 1991-05-07
Abstract: The equipment is for a multiple wood-planing machine, having adjustable feed rollers spaced apart in the feed direction and bearing against the surface of the work. Rotary planing tools are similarly mounted and adjustable, some of them on slides, and work against the different faces. A feeler mechanism (2) is mounted on a slide (1), having one or more movable components (5, 6). As the slide is moved forward in relation to others, these come to bear against feed rollers (7, 8) and/or their shafts (9) and actuate a limit switch (10) stopping the forward movement. USE/ADVANTAGE - No collision between machine parts even through operating errors.

Title: High-power reverse-flow-scavenged two-stroke engine - features supercharging by continued admission of air through diaphragm control to scavenging port before fuel injection
Inventor: JURACK KURT
IPC: F02B29/00
Filed: 1991-06-04
Abstract: Air is inducted (8) and lubricant injected (12) during the downward stroke which compresses air in the crankcase (13) until the piston (1) uncovers the exhaust port (9) leading to a rotary valve (3) of wider cross-section (5). The partial vacuum draws air through the scavenging port (10). The compressed air flows through the transfer port (7) into the combustion chamber while the valve (30 rotates to half-close the exhaust port (9) before fuel is injected (14). The diaphragm control (11) continues to admit air until the scavenging port (10) is closed. ADVANTAGE - Engine power and efficiency are increased without loss of fuel.

Inventor: FOERSTER HARALD PROF DR MED
IPC: C08B35/02
Filed: 1991-07-11
Abstract: In order to prepare physiologically tolerated water-soluble starch esters, the invention proposes that starch is converted by acid hydrolysis or enzymatic hydrolysis to a partially hydrolysed form with a mean molecular weight in the range from 10,000 to 500,000 Daltons. This partial hydrolysate is then acylated, in aqueous solution, with the anhydride or halide of an aliphatic monocarboxylic acid with 2 to 4 carbon atoms or an aliphatic dicarboxylic acid with 3 to 6 carbon atoms, or mixtures thereof, and an alkalinization agent, to give a product with a substitution ratio in the range from 0.1 to 1.0 mole/mole. Salts are removed from the resulting reaction mixture. The starch esters thus obtained are highly suited for clinical use, in particular parenteral administration and administration in the diet.

Title: Fluidised bed bag filter - for simultaneous dust and noxious gas removal from industrial waste gas
Inventor: JIPP ROLF DIPL ING
IPC: B01D46/02
Filed: 1991-07-19
Abstract: In a fluidised bed bag filter and a process for simultaneously dedusting and cleaning industrial waste gases, tubes are spaced about the filter bags in the dust chamber so that the higher concn. gas-dust-additive mixt., entering the top of the dust chamber, flows downwardly outside the tubes into a hopper for initial dust removal and gas cleaning and then the lower concn. mixt. flows upwardly in the tubes for residual dust removal and gas cleaning by the filter bags. The tubes pref. have conical ends in the region of horizontal supply of the gas-dust-additive mixt. to cause reactant dispersion and turbulence for enhancing noxious gas removal. The dirty gas supply pipe pref,. has motor-driven flap valve which allows passage of e.g. 110 percent of the total gas amt. in the open position and e.g. 90 percent of the total gas amt. in the closed position. ADVANTAGE - The filter allows simultaneous dust removal, desulphurisation, NOx removal and aerosol removal and is esp., useful for equalising the fluctuating gas cleaning levels of a preceding absorber or fluidised bed combustion unit.

Abstract: A transducer for inductively generating a measurement signal which reproduces the relative position of two bodies which can be moved with respect to one another comprises at least one exciter coil fed with alternating current for generating a magnetic flux, a measuring coil arrangement across which voltages can be picked up from which the measurement signal is derived, and a flux guiding device of ferromagnetic material which guides the magnetic flux generated by the exciter coil on an annularly closed measuring path in such a manner that at least a part of the magnetic flux passes through the magnetic coil arrangement, and at least one of the voltages which can be picked up across it changes in dependence on the movement of one of the two bodies with respect to the other one. To achieve a particularly high measuring accuracy and fidelity of characteristic, the measurement signal is formed as a quotient of two intermediate signals, at least one of which depends on the instantaneous position of one of the two bodies with respect to the other one, and it is ensured that each of the intermediate signals includes differences (W U1, W U2) of voltages supplied by the measuring coil arrangement (30). <IMAGE>

Patent DE-4209797-A1 (DE)
Inventor: SCHROEDER JUERGEN
IPC: H04B10/2507
Filed: 1992-03-26
Abstract: A method for the bi-directional transmission of digital data via an optical fibre is specified, by means of which in each case the bits of data streams to be transmitted are compressed packet by packet in constant number by factor of >2 to form bursts without changing the transmission rate. The bursts of one transmission direction are transmitted by a station in the intervals between the bursts of the other transmission direction from the respective transmitter via the optical fibre to the other station. To determine the transmission rates in the stations, mutually independent external clock generators are used at the two ends of the optical fibre. If the frequencies of the two clock generators deviate from one another, the bursts of the data stream with the lower transmission rate are in each case shifted by one bit width of the associated continuous data stream at intervals compared with the bursts of the other data stream. The respective receiver is informed of the shift in the bursts by the burst preceding the first burst to be shifted by means of at least one corresponding information bit.
