Inventor: NIKOLAISEN JOHNNY
IPC: C01F11/36
Filed: 1987-10-06
Abstract: The present invention relates to a method for purifying calcium nitrate melt/solution separated from the mixture obtained by dissolution of rock phosphate with nitric acid. The melt contains fluorine and phosphorus as main contaminants. The mol-ratio phosphorus/fluorine in the crude calcium nitrate melt/solution is adjusted to 3.5>P/F>0.3, possibly by extra addition of a phosphorus compound, and the mixture is then neutralized by ammonia to pH = 5-6. The precipitate thereby formed is removed while the filtrate, which is a purified nitrate of lime melt, is evaporated and further processed. The purification can be carried out in two stages, with a P/F-ratio in the first stage of 0.3-3 and 1-3.5 in the second stage. Phosphoric acid or a phosphoric acid containing solution is used as phosphorus compound.

Abstract: An auxiliary electrode for improving the consumption of oxygen in a gas-tight, sealed alkaline secondary cell is comprised of a synthetic nonwoven fabric and a film rolled onto the fabric. The film is a PTFE-bound activated carbon, and the side of the nonwoven fabric receiving the film is first impregnated with an aqueous cellulose ether mixture to develop a three layer structure including a highly porous, hydrophobic layer made of the nonwoven material, left in its original state and facing the electrolyte or gas supply, a hydrophilic impregnated layer, and a catalytically active hydrophobic consumption layer electrically connected with the cell's negative electrode and constituting the preferred location for oxygen reduction, at the resulting hydrophobic/hydrophilic transition layer. The auxiliary electrode is located outside of the ionic path between electrodes of opposite polarity, but in electron-conducting contact with the negative electrode, excluding the auxiliary electrode from unwanted interaction with the NO2/NH3-auto-discharge path.

Abstract: An injection molding thermal gated nozzle having a nose portion which extends forwardly to the cavity. The nozzle has a melt channel which extends through the nose portion to form the gate. An integral electric heating element has a forward portion with a generally rectangular cross section and a number of adjacent coils which form an inwardly tapered inner surface. Part of the inner surface of the forward portion of the heating element forms an inwardly tapered portion of the melt channel adjacent the gate, This direct contact of the heating element with the melt reduces considerably the cycle time of the thermal gate. The forward portion of the heating element is shaped by compressing it between tapered dies. It is then mounted between forward and rearward portions of the nozzle, and the assembly is integrally brazed together in a vacuum furnace.

IPC: E02F3/92
Filed: 1991-08-19
Granted: 1995-08-29
Abstract: For excavation of a clay seabed, particularly in a coffer dam to expose a buried pipeline therefor a minimum of three water nozzles producing water jets  and the associated effects 16, 17 and 18 are used.  The nozzles are mounted on a disc 12 which can move horizontally and vertically and which rotates in a horizontal plane.   The effect 18  (if operated alone) would produce a trench 22 having sloping sides.   The two effects 16,  17 enable a trench having vertical sides to be cut and enable the disc 12 to be moved downwardly until obstructed by the base of the trench.  The three nozzles are equiangularly spaced about the axis.  The rotation of the disc 12 makes the effect of the nozzles possible.

Granted: 1999-04-13
Abstract: A  system and method are provided  for combining multiple composite video signals into a single output data stream synchronised with  an  output  device.  The  system  includes means for decoding incoming composite video  signals into their  constituent  components,  memory  means  for  storing signals temporarily to  synchronise  such signals with the output  device,   and  a  multiplexor  for  combining  the synchronised signals for application to the output device. An  analogue  to  digital  converter  (ADC)  is  arranged  to convert incoming composite video signals into digital form, a digital memory is arranged to receive the digital output of the ADC, and a decoder is provided to sample the contents of  this  memory  under  the  control  of  timing  signals synchronised with the output device to develop synchronised digital  samples relating to the incoming composite video signals. These digital samples are then transferred to the multiplexor to enable the multiplexor to develop the single output data stream. This system requires less memory space than needed by prior art systems and enables high quality colour representations such as 24 bit RGB to be developed without increasing the memory requirement of the system.
