Title: Method of production of n-cyclohexylbenzothiazole-2-sulfenamide
Inventor: PODMANICKY STANISLAV
IPC: C07D277/80
Filed: 1993-05-26
Abstract: A method of production of N-cyclohexylbenzothiazolyl-2- -sulfenamide by reacting 2-mercaptobenzothiazole, which has the form of a raw product mould of a high-pressure aniline, carbon disulphide and sulphur reaction, with cyclohexylamine that is dosed in a mole ratio ranging from 1.5 to 5.0 per 1 mole of 2-mercaptobenzothiazole and with sodium hypochlorite that is dosed in a mole ratio ranging from 1.5 to 1.5 per 1 mole of 2-mercaptobenzothiazole, in a single mixed reactor by simultaneous dosing all three reaction components, at 10 - 80 degrees Celsius, or in two continual mixed reactors arranged in succession. In a first phase, cyclohexylamoniumbenzothiazolyl- -2-mercaptide is prepared at from 30 to 80 degrees Celsius, which compound is, in a second phase, oxidised with sodium hypochlorite at from 10 to 80 degrees Celsius thus obtaining cyclohexylbenzothiazolyl-2-sulfenamide. N-Cyclohexylbenzothiazolyl-2-sulfenamide is thereafter filtered from the reaction mixture. A filter cake is washed with an aqueous cyclohexylamine solution. Said aqueous cyclohexylamine solution used for the washing of the filter cake is reused for the reaction, optionally with an addition of concentrated cyclohexylamine.

Title: Process for producing granulate by spray granulation in fluidized bed and apparatus for making the same
Inventor: SCHUTTE RUDIGER
IPC: C01D7/38
Filed: 1996-04-03
Abstract: The invention concerns a process for producing granulates by fluidised bed spray granulation and a device therefor. Liquid starting substances can be converted into granulates by fluidised bed spray granulation. In order to ensure a high material throughput, a large number of nozzles which are also sensitive to blockages and encrustations must be installed. The invention makes it possible to avoid the drawbacks of prior art processes in that at least two at least partly facing spray nozzles (8) are arranged and the sprayed quantities are set in such a way that their sprays meet within the fluidised bed and there is no substantial overspray on a surface (4) bordering the fluidised bed or from the bed itself. The sprays from two facing spray nozzles meet either frontally or enclose an angle of less than 180 DEG ; this angle is preferably between 150 and 180 DEG . The device of the invention comprises a flow channel (1) with lateral spray nozzles (8), whereby two precisely or staggered opposite spray nozzles are directed in such a way that the sprays meet within the fluidised bed.

Title: Process and apparatus for regular distribution of three-phase electric load
Inventor: DAVID YAIR
IPC: H02J3/26
Filed: 1996-05-17
Abstract: An apparatus for and method of evenly distributing an electrical load across a three phase power distribution network. The current in each incoming phase and in each branch circuit is measured by a plurality of current sensors. The output of the current sensors are monitored by a processor. Associated with each branch circuit is a multi-pole switch and a conventional circuit breaker. Each switch is able to connect its corresponding branch circuit to any incoming phase or to disconnect the branch circuit from all three phases. The processor periodically monitors the current flowing through each incoming phase and based on branch circuit load conditions, reprograms the switches to keep the branch circuit loads evenly distributed across all three incoming phases. In another embodiment, a summing circuit combines the current capacities of all three incoming phases into a single summed output. This output is subsequently rectified and used to generate a single phase AC voltage which feeds all branch circuits in the system.
