Granted: 1992-08-04
Abstract: Abstract of the Disclosure:     In a repeater arrangement supplied with a sequence of input multiplexed signals to produce a sequence of output multiplexed signals, with stuff signals included in each of the input and the output multiplexed signals, the input multiplexed signals are demultiplexed by   demultiplexer into a plurality of demultiplexed signals assigned to channels and are stored in first-in-first-out (FIFO) memories with the stuff signals destuffed.  Stuff information related -to the destuffed signals is memorized in a stuff memory to be sent to a multiplexer.  The multiplexer carries out readout operations of the respective FIFO memories with reference to the stuff information by the use of readout pulses which have the same rate and which can reproduce the stuff signals.  A phase comparator compares phases of preselected pulses derived by the multiplexer and the demultiplexer with each other and controls a single phase locked oscillator coupled to the multiplexer.

Title: Method of drying a paper board or paper web
Inventor: LEHTINEN JUKKA
IPC: D21F5/00
Filed: 1989-01-12
Granted: 1992-12-08
Abstract: Abstract A method of drying a fibre web such as a paper or paper board web, wherein air is first removed from the web and a dryer felt, whereafter they are led together between two parallel metal bands  moving at the same speed as the web and the felt. For drying the web, the band on the side of the web is heated by means of a heating device before the band reaches the drying zone and, correspondingly, the band on the side of the dryer felt  is cooled before the band reaches the drying zone and comes into contact with the dryer felt. In the method, for adjusting the mechanical 2 compression exerted perpendicularly on the surface of the web,  the temperature of the cooling band is adjusted so that the difference between the condensation pressure of the steam condensed on the surface of the band on the side of the dryer felt and the pressure acting on the outer sur-face of the bands is substantially equal to the desired mechanical Z compression. Further, the drying rate of the web is adjusted by adjusting the temperature of the heated band by means of the heating device in such a way that a desired amount of water can be evaporated from the web within the drying zone. Since the pressure loss created by the steam flowing through the dryer felt is substantially insignificant with respect to the condensing pressure of the steam condensing on the surface of the band, and the temperature  difference  between  the heated band  and  the cooled band affects substantially this pressure loss only, these adjustments do not substantially affect each other and they can be carried out in desired order and adjusted suitably in view of the properties of the web to be dried.

Abstract: ABSTRACT A method is provided for enhancing processing and evaluating seismic data.  More particularly, a novel method is described for enhancing and evaluating common depth point seismic data.  Common depth point (CDP) gath-ers of seismic signals are processed to suppress random noise and coherent noise and to enhance primary reflection events while preserving geologically-induced amplitude variations as a function of range for the primary reflection events.  The processed CDP gathers of seismic signals can then be processed to obtain attributes descriptive of amplitude variations as a function of range for the selected primary reflection events whereby forma-tion lithology and fluid content can be evaluated.

Abstract: WEIGHT-ON-BIT AND TORQUE MEASURING APPARATUS               ABSTRACT OF THE DISCLOSURE    A drill String sub is disclosed for measuring the torque and axial compression in the drill string.  The drill string sub includes an outer tubular housing and an inner sleeve type apparatus mounted thereto for amplifying the strain the  sensors measure.  The sub further includes a section for compensating for the axial stresses due to the local pressure differential between the drill string bore and the well bore annulus and for the thermal gradients occurring during operation.  This  section includes a balance tube for isolating the internal bore pressure from acting on the strain amplifier and for creating an upward axial force on the tubular housing and strain amplifier which is responsive to this pressure differential to counter the axial stresses mentioned above.  The sensors are encapsulated in oil to avoid the effects of the corro-sion and electrical shorting which are promoted by drilling fluids.

Abstract: A centrifugal grinding mill including a grinding chamber of substantially circular cross-section with respect to an axis of symmetry and constrained to have nutating motion about a relatively stationary axis, a support for supporting the grinding chamber, a feed passage in communication with the grinding chamber, a driving assembly for driving the grinding chamber about the relatively stationary axis, and a constraint assembly for determining the form of nutating motion of the axis symmetry of the grinding chamber. The nutating motion of the grinding chamber during operation of the grinding mill causes a grinding charge carried in the grinding chamber to dilate and perform a tumbling motion within the grinding chamber. Further, the grinding chamber has a surface configured to exert pressure on the grinding charge so as to limit its dilation and provide effective containment of the grinding charge.

Abstract: In accordance with the principles for transcutaneous measurement of a blood parameter, such as the partial pressure of a blood gas, an electrochemical measuring electrode device (1) is applied to the skin surface (2) of a person. The electrode device comprises a body (10), e.g. a thick film substrate, which is thermostated to a predetermined temperature and, furthermore, includes sensor means (11) together with a membrane (14) confining an electrolyte solution within an electrolyte reservoir (15). Furthermore, the electrode device includes a jacket comprising an annular metallic body (16), a metallic body (4) and a thick film substrate (8) which is thermostated to the same temperature as the body (10) of the electrode device. When the body is brought into contact with the skin surface, an annular surface part of the jacket is also brought into contact with the skin surface so that a virtual heating jacket is established in the skin beneath the annular surface part so as to substantially direct all heat flow from the body to tissue directly beneath the skin surface. By measuring the power supplied for thermostating the body to the predetermined temperature, the local capillary blood flow in the tissue (2) beneath the skin is measured, and the blood parameter in question is measured by means of the sensor means (11). In an alternative operational mode, the electrode device is adapted to measure deep body temperature by thermostating the jacket to a temperature so that the temperature registered by a temperature sensor of the body and the temperature registered by a temperature sensor of the jacket are identical to one another and, consequently, identical to the deep body temperature.

Abstract: The system includes vertical posts with apertured disks secured thereto at intervals, coupling heads, wedge-like keys, scaffold pipes, coupling head extensions, and tank-link heads. Each coupling head has a horizontal slot receiving an apertured disk when the head is pushed into mounted position thereon, and has top and bottom key-receiving openings above and below such slot. A wedge-like key extends down through the top key-receiving opening, through a disk aperture, then through the bottom key-receiving opening, fastening the coupling head to the disk. Coupling heads for horizontal scaffold pipes have extensions insertable into the pipes. Diagonal scaffold pipes have tang-link heads, whose tank has an aperture for a pivot provided on an associated coupling head. Conventionally, the disks, coupling heads and pipes are all made of steel, the disks of 9 mm thickness and 122 mm diameter. The disclosed lighter-weight version employs disks and scaffold pipes made not of steel, but of light metal such as aluminum. The coupling heads although still of steel are differently designed, employing a smaller volume of material and thus lighter in weight. The disks are of 10 mm thickness and 124 mm diameter, producing a 33% loadability increase. Numerous other dimensional and configurational modifications of the standard elements compensate for any structural strength inferiority compared to the standard elements, but the herein disclosed lighter-weight versions thereof remain compatible with, and can be freely intermixed with, the heavier-weight standard elements.
