Title: Removal of ammonia from isocyanic acid-ammonia mixts. - by adding an ether at specific temp. and cooling, so that an isocyanic acid-ether adduct condenses out and ammonia is sepd. as gas
Inventor: STERN GERHARD DIPL ING DR
IPC: C01C3/14
Filed: 1989-08-29
Abstract: Ammonia is removed from gaseous mixts. of HNCO and ammonia (I) by adding an ether (II) to the mixt. at 250-600 deg.C and then cooling. An HNCO/ether adduct condenses out and the ammonia is sepd. and removed as gas. Pref. the reaction mixt. is brought into contact with a diluent and cooled; (II) is added at 320-380 deg.C.; (II) is a cyclic ether or an ether of formula R1O-(R3-O)n-R2 (with R1, R2 = linear or branched alkyl, aryl, alkylaryl or aralkyl; R3 = linear or branched alkylene, arylene, alkylarylene or aralkylene; n = 0-5), pref. a dialkyl or diaryl ether; the adduct-forming ether (II) is also used as diluent, pref. in excess, so that when the mixt. is cooled, (II) serves as diluent for the adduct. USE/ADVANTAGE - HNCO is useful for the synthesis of unsymmetrical ureas, carbamates, thiocarbamates, organic isocyanates, etc.; mixts. (I) are obtd., e.g. by thermal decompsn. of urea; the process enables the direct prodn. of a stable HNCO/ether adduct from such mixts. without the formation (and subsequent decompsn.) of cyanuric acid; the adduct can be used directly in the above syntheses.

Title: Apertured support plate for catalyst receives loose fibres - before bonding, compaction and catalyst application to interstices
Inventor: GRIMM DANIEL
IPC: F01N3/28
Filed: 1989-08-31
Abstract: The basis for a catalytic plate is formed by applying a loose mass of fibres, esp. metal fibres (3) to both faces of a metallic support structure (1) of woven, knitted or netted wire, or possibly perforated or expanded metal sheet. The fibres are bonded to the support structure, esp. by sintering, to provide a stable structure. A rolling or other flattening process modifies the reinforced structure to the desired catalytic plate thickness, producing level surfaces (8,9). Catalyte material is then applied in slurry of powder form to fill the interstices of the structure, which may finally be sprayed with a binder. ADVANTAGE - No fibres need mixing into the catalyst itself, and the final prod. is resistant to abrasion, flaking and temp. variations.

Title: Catalyser protection by detection misfiring cylinder detection - cutting of fuel to misfiring cylinder and making fuel mixt. to remaining cylinders leaner
Inventor: KLENK MARTIN DIPL ING
IPC: F02D41/14
Filed: 1990-01-26
Abstract: A method of protecting a catalyser from overheating involves using a cylinder selective method of misfire detection and interruption of the fuel supply to a cylinder in which a misfire is detected. When the fuel supply to a cylinder is cut off, the fuel mixture delivered to the remaining cylinders is made leaner. If the fuel cannot be cut off owing to an injection valve fault, the mixture is enriched for all cylinders and the engine power limited.

Title: Claw clutch for locking differential gear - has small holding force and release force on sliding sleeve
Inventor: FRIEDL REINHARD
IPC: F16D11/08
Filed: 1990-07-07
Abstract: The claw clutch has a sliding sleeve (70) which slides the movable half (60) of the clutch (6) against the fixed half (50) via intermediate members (77) spread out round the circumference, thereby closing the clutch and then fixing with an axially aligned locking face (74) each intermediate member (77) axially between a support face (64) of the movable half (60) and an axially fixed retaining face (4) in the locking position. The support face (64) and the retaining face (4) form a wedge angle (65) so that with a closed clutch (6) a torque of the clutch (6) produces via an axial deflecting force of the coupling teeth (51,61) at each intermediate member (77) a radial force which presses the intermediate member (77) against the locking face (74). When the sliding sleeve (70) is moved back and thus releases the intermediate members (77) the torque opens the clutch. USE - Claw clutch for differential of motor vehicle.
