Title: Method and apparatus for pumping high consistency pulp
IPC: F04D7/04
Filed: 1988-07-01
Abstract: The present invention relates to a method and apparatus for pumping high consistency pulp, which invention is especially suitable for pumping high consistency fiber suspensions in the pulp and paper industry. One of the problems in the prior art techniques has been the difficulty of bringing high consistency pulp to the impeller of the pump or like, because high consistency pulp tends to form strong fiber network, which stops the pulp flow. A method has been developed as a solution to the problem, in which liquid is discharged from pulp during the pumping process and the liquid is fed back to the pulp to be pumped upstream of the pumping. This method is enabled by an apparatus, in which at least part of the surfaces of the pump (1) are arranged with filter surfaces (6, 7, 8, 9, 10), through which the liquid separated from pulp is returned either directly in front of the suction opening (11) of the pump (1) or to some other suitable place in the mass tower.

Title: Method for cleaning soil or the like, contaminated by extractable organic pollutants
IPC: B01D11/02
Filed: 1989-01-27
Abstract: In a method for cleaning earth soils or similar soil materials polluted with organic harmful substances, the latter are extracted by means of a suitable solvent from an aqueous suspension of the soil materials. After the solvent which has taken up the extractable organic harmful substances, the solvent is distilled and recycled into the process. The distillation bottom product, which contains the extractable organic harmful substances, is disposed of, for example, by incineration or in a landfill. The remaining suspension is separated into water and soil, and the aqueous phase is recycled into the process. If the water is polluted with free cyanides, it must be passed over a purifier earth for removing the cyanides, before it is used again.

Title: Op branching for starting micro-routines
IPC: G06F9/26
Filed: 1989-11-24
Abstract: A mechanism for translating a particular macroinstruction 
into its associated microprogram routine in a general 
purpose microprogrammed computer where the macroin­
struction is capable of execution by either hardware 
or by microprogram. A table-look up approach is 
employed for a microprogrammed macroinstruction. The 
table is embedded in random-access-memory and contains 
entries representing the origins of various micro­
program routines to execute the macroinstruction. The 
table entries are addressed by bits generated from the 
operation-code of the macroinstruction. The output of 
the table is used to address a single level control 
store containing the microprogram routines. Hardware 
is assembled in a single facility that is accessible 
by the microprogram routines to minimize the size of 
the microprogram routines required to execute the 
macroinstruction.

Title: Minimizing the interconnection cost of electronically linked objects
IPC: G06F17/50
Filed: 1990-05-25
Abstract: The interconnection costs of electronically linked 
objects is minimized by the successive partitioning of the 
initial logic design. The partitioning is based upon the 
electrical properties of the drivers and loads of the 
linked objects forming the design. Further, time critical 
connections are weighted so as to further minimize 
interconnection cost. A further method refines the result 
of the successive partitioning by calculating each linked 
object's contribution to the overall delay of the design. 
Both the design of device function and timing and the 
physical realization of the electronically linked objects 
are solved jointly to make use of the information 
available from the logical and physical designs.
Patent EP-0403972-A3 (EP)
IPC: H04N3/18
Filed: 1990-06-15
Abstract: A transformer coupled amplifier drive circuit (40,60) 
and method especially suited for providing a saw-tooth 
current waveform to an inductive load (32) for horizontal 
deflection applications in CRT monitors and the like are 
described.  
     When the input switch (44) is closed, the input of the 
amplifier (26) is energized by a current (45,65) through the 
series connected primary (48) and energy is stored in the 
transformer (46) magnetizing field and in the amplifier 
(26). Conduction in the transformer (46) secondary (50) is 
blocked by the diode (56).  
     When the input switch (44) is opened, the input 
charging current (45, 65) stops and the collapsing primary 
(48) magnetizing field produces an oppositely directed 
current (47,67) which flows through the secondary winding 
(50), the diode (56), the series connected inductor (52) and 
the input to the amplifier (26). The demagnetization energy 
stored in the transformer (48) cancels the energy stored in 
the amplifier (26), thereby reducing total dissipation, and 
the inductor (52) controls the fall time independent of the 
rise time.

Abstract: A nonlinear noninverting amplifier design (22) for 
receiving and amplifying an input signal (20) in an 
optical communication scheme having a nonlinear inverting 
feedback (32) is disclosed. The inverting feedback (32) 
varies nonlinearly with the input signal (20) to avoid 
saturation of the amplifier (22) while providing a zero 
state input amplitude signal to reduce the amplitude of 
the input signal (20) required to turn-on the feedback 
(32), thus allowing the amplifier (22) to operate with a 
wide variation of optical generators, paths, and 
converters. A nonlinear noninverting amplifier design 
(22) is provided which eliminates the need for automatic 
gain control circuitry and can be designed as an 
integrated circuit.
