Abstract: A process is disclosed for the production of free-flowing, non-caking, stable granular ammonium sulphate containing micronutrients comprising granulating ammonium sulphate in the presence of a granulating aid which is stripped zinc electrolyte derived from an electrolytic zinc operation.     An  effective  amount  of  stripped  zinc electrolyte is used to yield a final ammonium sulphate product containing about 0.4% to 1.3% by weight zinc, up to about 0.16% by weight magnesium and up to about 0.09% by weight manganese.  The stripped zinc electrolyte, typically containing 20-25 g/L zinc,  2-4 g/L magnesium,  1-2 g/L manganese and sulphuric acid, may be added during reaction of ammonia and sulphuric acid prior to granulation.   A free-flowing, non-caking, hard, ammonium sulphate granular fertilizer having a pH of about 2 to 7.5 as 10% solution, containing by weight 0.4% to 1.3% by weight zinc, up to about 0.16% by weight magnesium and up to about 0.09% by weight manganese is produced.

Abstract: ABSTRACT            The present invention provides a computer system and method of using the  same.  Add-on memory cards  for  the  system  are provided which cards have error correction code logic on the card, and logic to do partial writes of data words. The system has a central processing unit (CPU), a BUS interconnecting the CPU and the  add-on memory cards. The  CPU or  associated components are configured to write data and read data from the add-on memory as several data bytes constituting data words. The system is further configured either within the CPU or as a separate function to generate parity bits associated with each of the bytes of data the CPU writes to the add-on memory and to read parity bits associated with data the CPU reads from the add-on memory and regenerate new parity bits and compare the newly generated parity bits with the original parity bits to detect data errors on data read from the add-on memory. The system itself does not contain error correction code (ECC). The add-on memory has ECC logic to identify any byte having a single bit error in the data bytes or the parity bits written by the CPU to the add-on memory and to correct all single bit errors in data read from the add-on memory to the CPU. The error correcting code includes logic to generate parity bits in the data bytes written by the CPU to the add-on memory and logic to compare the parity bits written by the CPU with those generated by the error correcting code logic. Also provided is a circuitry card technique to block or by-pass error reporting and correcting during initialization.

Title: Process for catalyzation in electroless plating using chitosan or a chitosan derivative
Inventor: OMURA YOSHIHIKO
IPC: C23C18/20
Filed: 1995-02-16
Abstract: There is disclosed a novel process for catalyzation for trapping of a catalyst metal involved with the adhesion of an electroless plating to a substrate. The process is carried out by employing neither the sensitizing-activating method nor the catalyst-accelerator method.            Specifically, in forming an electroless plating on the surface of a non-conductive substance as a substrate, the surface of the non-conductive substance is coated with a treatment liquid containing at least chitosan or a chitosan derivative before the steps of catalyzation and electroless plating to form a hydrophilic coating film on the surface of the non-conductive substance.  The hydrophilic coating film traps and fixes thereon a catalyst metal such as palladium through chemisorption thereof by the action of chitosan or the chitosan derivative.  As a result, a state that a sufficient amount of the active catalyst is borne on the surface of the substrate can be secured in the step of electroless plating to enable the electorless plating strong in adhesion to the substrate to be uniformly and efficiently formed on the surface of the substrate.

Title: Stage lighting lamp unit and stage lighting system including such unit
Inventor: HUNT MARK ALISTAIR
IPC: H05B37/02
Filed: 1993-09-21
Abstract: A stage lighting lamp unit includes a processor for receiving control data from a remote console. Beam orientation data for the lamp unit is passed to the lamp in the form of the x, y and z co-ordinates of a point in space through which the beam is to pass. The processor divides the required lamp travel into a number of stages dependent on execution duration data sent with the position data, and calculates, for each stage, a new value for pan and tilt angles for the lamp. These values are passed to pan and tilt controlling co-processors which control servomotors for pan and tilt operation. The lamp unit also incorporates a rotatable shutter for interrupting the lamp beam when required. The shutters of all the lamps in a system can be instructed from the remote console to open and close in synchronism, thereby providing a stroboscopic effect.

Abstract: METHOD FOR CONTROLLING AN OZONE BLEACHING PROCESS       ABSTRACT A method for controlling the gas recycle loop of an ozone bleaching process wherein an ozone generator produces an ozone containing gas from an oxygen containing feed gas and delivers the ozone containing gas to an ozone reactor at a variable flow rate responsive to reactor ozone demand.  Pulp is bleached with the ozone containing gas, thereby producing an exhaust gas having a flow rate that varies in response to the flow rate of the ozone containing gas delivered to the ozone reactor.  The exhaust gas is then recovered and its flow rate is modified within the recycle loop so that an amount equivalent to reactor ozone demand is returned to the ozone generators.  The oxygen content of the oxygen containing feed gas is monitored at or near the inlet of the ozone generator and an amount of fresh oxygen is supplied to the oxygen containing feed gas to obtain a predetermined level of oxygen therein .  Additionally, an amount of exhaust gas may be purged at a rate substantially equivalent to the rate fresh oxygen is supplied.  However, the pressure at the ozone generator is also monitored and the purge rate is adjusted in order to maintain constant pressure at the ozone generator.

Title: Predistortion method and apparatus for laser linearization
Inventor: CORNISH PETER W
IPC: H04B10/58
Filed: 1994-04-18
Abstract: A predistortion circuit reduces composite second order intermodulation distortion products inherently generated by a laser diode. A radio frequency signal is split into a primary and secondary signal and the secondary signal is amplified by an amplifier biased at a starvation current level so as to produce intermodulation distortion products having an amplitude relatively large compared to an amplitude of a fundamental generated by the amplifier. The amplitude and phase of composite second order intermodulation distortion products generated by the amplifier are adjusted so as to substantially match those inherently generated by the laser diode by the primary electrical signal, with the products being about 180° out of phase relative to those generated by the laser in response to the primary signal. The adjusted distortion products are combined with the primary electrical signal, and the combined signal is fed to the laser diode resulting in an output of the laser diode having minimum composite second order intermodulation distortion products.
