Granted: 2008-07-29
Abstract: A nozzle tor a pilot light tor a flare stack, the nozzle being formed of a housing defined by an encircling cylindrical wall, with radially extending openings formed circumferentially around the encircling wall, and is made of material resistant against breakdown in a sour gas environment at temperatures at least less than 1200°C, preferably 98% by weight alumina ceramic. A cage holds the nozzle, which includes a base plate having a central aperture and first and second sides, a tube extending into the aperture from the first side of the base plate and fixed to the base plate, and plural retainers extending from the base plate and enclosing the nozzle. To form a pilot for a flare stack, a gas conduit is connected into an interior cavity of the nozzle. The cage is attached to a flame stack. The retainer members pass through the nozzle to protect the retainer members from the corrosive environment in which the pilot operates.

Abstract: The object of the present invention is to achieve in the telephone network a new type of procedure and system for call control and to meet a need observed recently in the telecommunication business for calls rated below normal tariffs especially between certain predeterminable subscriptions. The system of the invention does not require any substantial system changes in the telephone network. In addition, calls between predetermined subscriptions can now be rated according to a special tariff and the changes can be easily and flexibly included in the normal invoicing. When the number of subscriptions per customer is limited to two, the common call number for all customers is the same, e.g. 020100. When this number is dialled, the call is directed to the wired network subscription specified in the subscriber number pair, which is stored in a database, when the call is made from a mobile station, and vice versa. When the number of subscriptions connected to the system by a customer is greater than two the common call number comprises a prefix part which is the same for all customers and on the basis of which the telephone network exchange recognizes the service call of intelligent network calls and specially rated calls, and a suffix part which is an integer and which, via the intelligent network, determines the desired individual subscription among the subscriptions selected to be included in the system by the customer.

Title: Process for preparing nicotinic acid
Inventor: ZACHER UWE
IPC: A23L33/00
Filed: 1998-11-10
Granted: 2008-09-23
Abstract: Nicotinic acid is produced from aqueous solutions of ammonium nicotinate by spray-drying. The nicotinic acid may be freed from residual ammonium nicotinate by a thermal post-treatment in a fluidized bed or under reduced pressure. The process is suitable, in particular, for working-up the reaction mixture produced in the oxidation of 3-methylpyridine with atmospheric oxygen, with the ammonia and, if appropriate, the water, being able to be recycled. Nicotinic acid ("vitamin PP") is an important additive for foodstuffs and feedstuffs.
