Title: Flow control method for short message service-busy subscriber
Inventor: ASTROM BO ARNE VALDEMAR
IPC: H04M3/46
Filed: 1995-11-29
Granted: 2007-03-27
Abstract: A flow control system and method in a global system for mobile communication (GSM) mobile telephone system for short message service (SMS). The SMS enables short text messages to be sent to and from mobile stations. The system and method is directed to a control for a service for messages sent to MSs (MT-SMs) and in particular to the case when several SCs send MT-SMs to the same mobile station subscriber. When several SCs send MT-SMs to the same subscriber, the first SC that establishes a short message dialog is allowed to be fully completed. While the short message dialog for this SC is established, any other SC attempting to send MT-SMs are detected and stored in a waiting list. After the short message dialog is completed, the same radio connection in maintained and each of the short messages corresponding to the SC addresses stored in the waiting list are sent by a first in-first to send principle.      More generally, the system and method controls messages sent by SMS during a busy condition which enable a better utilization of the network and the network entity resources.

Title: Process for the catalytic hydrogenation of aromatic nitro compounds
Inventor: BAUMEISTER PETER
IPC: C07C209/36
Filed: 1996-05-07
Granted: 2007-07-03
Abstract: One object of the invention is a process for the catalytic hydrogenation of aromatic nitro compounds in solution or in melt in the presence of hydrogen and at least one noble metal catalyst, nickel catalyst or cobalt catalyst, in which process a catalytic amount of at least one vanadium compounds is present, wherein the vanadium has the oxidation state 0, II. IV or V. It has been found that in the catalytic hydrogenation of aromatic nitro compounds the accumulation of hydroxylamines can be almost completely prevented by the addition of catalytic amounts of vanadium compounds, which usually results i n concentrations of < I% of hydroxylamine. The resulting hydrogenated products are whiter (purer) than those obtained without the addition of the vanadium compound because almost no azo or azoxy compounds are obtained. The hydrogenation, in particular the final phase, proceeds faster than without said addition. Accordingly, substantial advantages with respect to quality constancy and economy are obtained.

Granted: 2006-07-04
Abstract: The disclosure relates to a method of extinguishing fires, a fire-extinguishing compound and a fire-extinguishing system. The proposed method involves the preparation of a fire-extinguishing composition containing an oxidant and a fuel-binder, placing the composition in the area of the seat of the fire, initiating a sustainable fuel oxidising reaction producing combustion products in finely dispersed aerosol form, and then allowing the aerosol medium to act on the seat of the fire. According to the invention, the compositions in the aerosol products of combustion act in the immediate area of the fuel oxidation reaction to reduce the level of toxins and lower the equilibrium temperature of complete oxidation of the fuel-binder combustion products. To achieve this, a reagent is introduced into the aerosol combustion products of the composition which promotes a reduction in the equilibrium temperature of the full oxidation reaction of the fuel-binder combustion products. The reagent used consists of thermal disintegration products of a low-energy supplementary fuel. Also proposed is a compound suitable for the proposed method. The system is provided with a reactor containing means for reducing the level of toxins in the area of combustion of the composition.

Abstract: A dynamic splint has a bi-directional torsional dynamic tension unit (348) fastened between first and second struts (308)(388) to selectively deliver force opposing either extension or flexion. The tension unit (348) is mounted about a pivot post (34) and can be rotated between two positions. In the first position, the power unit is locked relative to the first strut (308) and the torsion spring opposes relative movement of the second strut (388) in a first direction. In the second position, the tension unit (348) is locked relative to the second strut (388). In this second position, the tension unit (348) opposes movement of the first strut (308) relative to the second strut (388), providing torsion in an opposite direction from that of the first position. Self-aligning contour plates (334) on the struts conform to the anatomy and provide a mechanical interlock to bony prominences on the patient's limbs.

Abstract: A rotary disc refiner includes a pair of spaced apart refiner discs for refining or grinding a material that typically is fibrous material such as wood pulp or the like. Pressurized vapor, typically steam, produced as a result of the refining or grinding is exhausted through a channel in the refiner disc which extends through the bo dy of the disc. Preferably, the channel is located in a refiner disc that rotates.

Title: Computer system and process for capture, editing and playback of motion video compressed using interframe and intraframe techniques
Inventor: HAMILTON JAMES
IPC: G11B27/034
Filed: 1998-03-30
Granted: 2007-02-27
Abstract: Random access to arbitrary fields of a video segment compressed using both interframe and intraframe techniques is enhanced by adding state information to the bitstream prior to each intraframe compressed image to allow each intraframe compressed image to be randomly accessed, by generating a field index that maps each temporal field to the offset in the compressed bitstream of the data used to decode the field, and by playing back segments using two or more alternatingly used decoders. The cut density may be improved by eliminating from the bitstream applied to each decoder any data corresponding to bidirectionally compressed images that would otherwise be used by the decoder to generate fields prior to the desired field.
