Abstract: PCT No. PCT/SE88/00182 Sec. 371 Date Aug. 23, 1989 Sec. 102(e) Date Aug. 23, 1989 PCT Filed Apr. 11, 1988 PCT Pub. No. WO88/08050 PCT Pub. Date Oct. 20, 1988.Apparatus for manufacturing pulp fiber from lignocellulose-containing material is disclosed, including a preheater, a defibrator with a pressurized housing, a conveying screw to convey the preheated lignocellulose-containing material from the preheater to the defibrator, a horizontal separator, a blow pipe for transferring the defibrated lignocellulose-containing material and steam from the defibrator to the horizontal separator, in which the horizontal separator includes a pulp outlet, a steam outlet, and a screw conveyor which includes screw threads which have a screw thread angle which substantially corresponds to the angle at which the blow pipe enters the horizontal separator. The screw conveyor in the horizontal separator feeds the defibrated lignocellulose-containing material from the blow pipe to the pulp outlet in the form of a pulp plug which maintains the pressure within the separator, and a steam transfer line is provided transferring the separated steam from the steam outlet to the preheater. The flow resistance in the blow pipe and the steam transfer line is less than the flow resistance in the screw conveyor between the preheater and the defibrator so that the steam flows from the defibrator to the horizontal separator and to the preheater. Methods for manufacturing pulp fiber from lignocellulose-containing materials utilizing this apparatus are also disclosed.

Abstract: Magnetic Susceptibility Imaging (MSI) comprises a means to magnetize the tissue to be imaged, such as a first Helmholtz coil, which produces a high-strength external magnetic field to which unpaired electrons of paramagnetic molecules of tissue, which includes primarily deoxyhemoglobin and oxygen, couple in a positive sense, and to which orbital electrons of diamagnetic molecules of tissue, such as proteins and water, couple in a negative sense to produce a secondary magnetic field. The imaging system further comprises a means to null the external magnetizing field, such as a second Helmholtz coil which, for example, confines the flux of both said coils to a single plane such that the component of the secondary field perpendicular to this plane is the only field with a nonzero component. The said secondary field component is detected by a detection means, such as an array of Hall voltage detectors. The detection is performed over a sample space, and the signals recorded of the said secondary field are used to reconstruct the magnetic susceptibility function of the body using the reconstruction means of the present invention, such as a Fourier Transform Algorithm.

Title: Automatic system for adjusting the output impedance of fast cmos drivers
Inventor: BELLA VALTER
IPC: H04L25/02
Filed: 1990-07-26
Granted: 1994-05-17
Abstract: Abstract An automatic system for adjusting the output impedance of fast CMOS drivers which measures and corrects impedance mismatch  between  a  dedicated  reference  driver  and  a dedicated   reference   transmission  line   and   which correspondingly adjusts the output impedance of a number of slave drivers.  The output impedance of the reference driver is measured by feeding a clock signal to the input of the reference driver and then by measuring the voltage at the input of the reference transmission line at the centre of the positive half of the clock signal.   The measured voltage is compared with a reference level and, accordingly,  a voltage pulse is supplied to charge or discharge a capacitor whose terminal voltage controls of the driver output impedances. The reference transmission line  is  terminated  by  a  resistance  equal  to  its characteristic impedance.
