Patent DE-19803897-A1 (DE)
Title: Ring seal suitable for positioning between two flange adapters in pipe line system meets international standards
Inventor: BARRY LEMON
IPC: F16L23/22
Filed: 1998-02-02
Abstract: The elements of the pipeline are connected with flanged elements positioned opposite each other and with a ring seal (1) between them. The joint area is covered by flanged fittings which are kept in place by means of bolts. The ring seal is made of Elastomer(RTM) or PTFE(RTM), shaped in order to cover the flanged area completely and has semi-circular recesses (2, 2A) for the insertion of bolts radial arranged around the outer edge.  By placing the seal (1) in a specific way the positioning of the recesses matches three different international standards for the connection of pipes.
Patent DE-19804196-A1 (DE)
Inventor: MOCK RANDOLF DIPL PHYS
IPC: G01M15/00
Filed: 1998-02-03
Abstract: In order to diagnose coupled piezo-mechanical systems, methods are used which utilise the electric characteristic curves of the piezo-element (11) contained in the piezo-mechanical systems. These electric characteristic curves contain information on the mechanical state of the whole piezo-mechanical system and this information can be interpreted by appropriate evaluation methods. This makes it possible to carry out a diagnosis which enables functional disturbances or failures of the piezo-mechanical system to be recognised (for example, the wear or failure of particular components). An important field of application is the diagnosis of fuel injectors controlled by piezo-actuators.

Patent DE-19808282-A1 (DE)
Title: Roof batten and ashlar stripper tool
IPC: E04D15/00
Filed: 1998-02-27
Abstract: The two sections (14,16) of the working foot (12) have gripper claws (18) which lie in the tipping plane of the stripper handle but in opposed directions to the side. One section of the foot (12) has an opposed claw to engage the ashlar or batten from below or from the side. The other section of the foot offers an abutment spaced outward to the side in the form of a bearing edge. The foot sections have downwards curved claws in the handle length sense (L) so both can act as gripper or bearing edges as required. Otherwise the sections can have separate claws and abutments or again one section is fitted with two spaced claws which are integral with the sheet metal bearer. This projects both sides from where fixed to the handle to form the foot sections (14,16).

Filed: 1998-04-06
Abstract: Preparation of chewable pastilles, containing e.g. a water-soluble polymer (I), active agent(s) (A) and additives/auxiliaries (including isomaltol as sugar substitute) involves predissolution of various components in water under specific temperature conditions before addition of (A).

The process involves: (i) predissolving the additives and auxiliaries, including isomaltol as sugar substitute, at constant stirring speed for at least 5-20 minutes at 90-130 deg C; (ii) boiling the obtained solution at 100-140 deg C for at least 15-45 minutes; (iii) predissolving (I) (preferably gum arabic) at constant stirring speed for at least 30-90 minutes at 85-110 deg C; (iv) forming the base mixture by mixing the products from (ii) and (iii) at constant stirring speed; and (v) cooling and incorporating (A) with constant speed stirring.
Patent DE-19826684-A1 (DE)
Title: Separation of oxygen from air for subsequent enrichment
Inventor: NOACK ANDREAS
IPC: F02M25/10
Filed: 1998-06-16
Abstract: Oxygen is separated from air by absorption at a relatively high pressure in a virtual molecular sieve and passes by centrifugal force into a comparatively low-pressure region where desorption takes place. Oxygen is absorbed in a virtual molecular sieve made of activated carbon fibers with pores of 0.5-0.7 nm. The fibers (22) run radially on a centrifuge disc whose surface is divided into two domains - a high pressure and a low pressure one. The domains are separated by a barrier (16), made of thermoplastic material, so that gas can only pass through the pores of the fibers. Atmospheric air is admitted at relatively high pressure at an air inlet (24). The absorbed oxygen, boosted by centrifugal forces, passes through the fibers and the barrier into the low-pressure domain (20) where it is desorbed and sucked out at an oxygen outlet (26). The oxygen is then used to enrich another air stream, e.g. the air intake to an IC engine, an incinerator plant, a glass furnace, etc. The unit can be small enough to form part of a motor vehicle.

The slurry is subjected to hydrothermal crystallization to obtain crystalline zeolite which is washed with water and oven dried. Fly-ash and caustic soda are mixed in the ratio of 1:1.2, ground and sodium aluminate or aluminum hydroxide are optionally added to obtain a fine homogeneous fusion mixture. The mixture is heated in an inert vessel at 500- 600  deg C for 1-2 hours to obtain a fused mass which is cooled, milled and mixed in distilled water for 8-10 hours, with simultaneous optional addition of sodium aluminate or alum solution, in the presence or absence of sodium chloride. An amorphous alumino-silicate slurry is obtained by optional addition of zeolite-A seeding. The slurry is subjected to hydrothermal crystallization at 90-110  deg C, for 2-4 hours, to obtain crystalline zeolite which is washed with water and oven dried at 50-60  deg C.
