Title: Process for the preparation of heteroalicyclic N-nitro compounds
Inventor: MILLAR ROSS WOOD
IPC: C07D263/26
Filed: 1992-01-16
Abstract: A method of preparing heteroalicyclic N-nitro compounds consists of the steps of reacting a heteroalicyclic N-monosilylated compound with dinitrogen pentoxide, preferably within an inert organic solvent and within the temperature range -10 DEG C to +10 DEG C, and separating the N-nitro product from the silyl nitrate co-product thus obtained. The nitrodesilylation method is capable of producing heteroalicyclic N-nitro compounds in high yields of typically 60 - 80%, and generates a silyl nitrate co-product which is relatively easy to remove by distillation in the presence of excess N2O5. Reagents containing two or more N-silyl groups per molecule can be employed yielding useful high explosive materials containing a corresponding number of N-nitro groups per molecule.
Patent DE-4232652-A1 (DE)
Inventor: HUENLICH KLAUS
IPC: H04L12/54
Filed: 1992-09-29
Abstract: Using the method according to the invention, the allocation of switching resources (VR) of a communications system (KS) is controlled for connections in which cells (Z) transferred to the communications system (KS) by a communication terminal (KE) are to be switched without loss of cells. In this method, a log-on information and resource requirement information (ai, ri) transferred during the connection signalling are entered connection-individually into a communications-system-related routing table (LT) and when the first cell (Z) to be transferred without loss is received, this and the further cells (Z) are switched with the aid of the registered switching resources (VR) if no resource availability information (rvi) dependent on the traffic load in the communications system (KS) is entered in the routing table (LT). If the switching is successful, a resource busy information (rbi) is inserted into the routing table (LT) as a result of which the switching resources (VR) are exclusively allocated to the connection for switching the cells (Z) to be transferred without cell losses. <IMAGE>

Patent DE-4236047-A1 (DE)
Inventor: BECK ERHARD
IPC: B60T8/36
Filed: 1992-10-24
Abstract: A hydraulic system with an antilock system and/or a drive slip control has a master cylinder (2), electromagnetically controlled inlet and outlet valves (5, 6) for pressure modulation and a hydraulic pump (8) for returning the hydraulic fluid diverted during the diminishing phase of the braking pressure or for supplying an auxiliary pressure. The hydraulic valves (5, 6), in particular the inlet valve (5), are designed in such a way that when the valves are controlled by an alternative signal or by a pulse sequence whose frequency or whose pulse duration/pulse pause ratio is set to the valve characteristics, the valve armature (9) takes a dosing position. This dosing position, and therefore the opening of the valve, depends on the alternative or pulse control signal and on the pressure differential acting on the valve armature (9). The noises caused in particular during regulation by means of the inlet valve (5) are thus considerably reduced.
