Abstract: A grinding and polishing apparatus wherein an air grinder is incorporated in the tool attaching spindle of a machining center main body in exactly the same manner as in the other exchange tools so that grinding and polishing operations can be performed. The tool attaching spindle is centrally formed with a tool mounting bore and a compressed air feed passage. The air grinder is attached to the tool mounting bore and driven by fluid being fed from the compressed air feed passage. The apparatus further includes air feed control means, whereby supply of fluid to the compressed air feed passage is started after the base portion of the air grinder is mounted in the tool mounting bore and supply of fluid is stopped immediately before the air grinder is removed from the tool mounting bore.

Abstract: In order to improve the accuracy of borehole survey systems utilizing probes with inertial components including inclinometers, two ring laser gyro units are included to provide rotation information 56, 58 to the system. When the probe is moving in a borehole, inclinometer information 50, 52, 54 is used 78 to produce a synthetic rotation signal 80 to take the place of a third gyro and the earth's rotation OMEGA , 68 is used 66 for a similar purpose in combination with signals from the two ring laser gyros when the probe is stopped (Vp = 0 at 74). Wire line velocity Vp, 60 is used in combination with the inclinometer and gyro information to provide signals representing the probe velocity and position (152). Coordinate transformations 64, 104, 126-130 are provided in the probe to transform the inertial signals and wire line velocity signals into earth reference coordinate system. Kalman filtering 142 incorporates non-inertial velocity data to reduce the effect of errors inherent in the generation of various input signals to the system. <IMAGE>

Abstract: A method of maintaining a given content of a substance A in an aqueous solution where it is continuously consumed and where the redox potential E, at least within the range of concentration used, approximately satisfies the equation:    E = G + F(x)   wherein x is the content of A, F is a function of x whose derivative dF/dx approaches zero when x assumes a high value, and G on the whole is independent of x but is influenced by other parameters, such as pH, temperature or the like. The addition of A is controlled in such manner that a set value of the redox potential is maintained. The set value is determined by increasing or decreasing the addition of A in a predetermined manner, whereupon the redox potential is measured, and the measured value is used for determining the set value. <IMAGE>

Abstract: A refiner (50) for producing mechanical pulp has greater spacing between bars (13,24,124) of the refiner grinding elements than is conventional. The grooves (15) between the bars have a sloping bottom (16,25,125) making an angle of about 1-30 DEG  (preferably 5-20 DEG ) with respect to a straight line between the bars. The width of the grooves is about 10-50 mm. The relative rotation of the refiner elements (whether disk shaped (20,21), cylindrical, or conical (10)) with respect to each other results in sequential refining by providing a moving tension field, with successive compressions before impacts, and expansions, achieving increased fiber flexibility, more fiber rolling motion, and less fiber cutting. Pulp produced has increased fiber flexibility yet maintains a high content of long fibers, and higher refiner capacity also ensues. Also, the refiner can be used to mix treatment chemicals -- such as bleaching chemicals in liquid form -- into kraft pulp at high consistency (e.g. about 30-55%).

The placer arms (10) should be mounted on the slides (4) and adjust toward their pivot axis (14) together with the slides. ADVANTAGE - Placer arms adjust to suit pipe length and ar mounted on program controlled magazine slides for correctly timed movement.

Abstract: A multi-roll calender for treating a web material, of the type which develops a linear force, has at least two rolls stacked one above the other in a press plane. A lower roll is constituted as a sag-compensation roll. The other rolls in the calender stack are all equidistant relative to the sag-compensation roll, i.e., they are supported the same distance away from the two supports of the rolls. One of the outermost rolls (either the top or the bottom roll) is fixed in a stand while all the other rolls are movably mounted. The moveable rolls can be acted upon by support forces acting in the plane of the stack. The support forces and the internal pressure of the sag-compensation roll are adjustable via a control device, e.g., a computer, so that even when the rolls sag, the linear force distribution of the rolls is identical over their width.

Abstract: The process is , and comprises adjusted periods with alternating high and low sound strength through signal damping or signal amplification. An electrical signal is emitted from a signal emitter (11) such as a tape recorder and is received-processed by one or more sound reproduction units (13,14). The electrical signal is damped or amplified periodically (cyclically). Each period is adjusted with a section where the sound reproduction unit (14) emits sound at low strength and a section where sound is emitted at high strength. This is achieved using at least one signal damping-amplifying unit (12) connected between the signal emitter (11) and the sound reproduction unit (14) and having a clock circuit, time adjustment unit, an activating memory circuit, a deactivating memory circuit and a damping-amplification circuit.

Abstract: A method for controlling an electrostatic precipitator unit, which comprises discharge electrodes and collecting electrodes. Between the electrodes a varying high voltage is maintained by a pulsating direct current supplied thereto. Under the action of the electric field between the electrodes, the particles, charged by the current therebetween, are moved towards the collecting electrodes and deposited thereon. Dust deposited on the collecting electrodes is removed by mechanical rapping. One or more mechanical impulses are supplied to the electrodes individually or in groups in a predetermined manner. All collecting electrodes of the unit are cleaned during recurrent, relatively short, rapping periods separated by rapping intervals of essentially longer duration. During the whole rapping period or during an introductory part of the rapping period, the voltage between the electrodes is reversed in relation to the voltage between the electrodes during the intervals between the rapping periods. The frequency, pulse charge and/or pulse duration of the pulsating direct current are varied, thereby obtaining a plurality of combinations of frequency, charge and duration. An optimal combination of frequency, charge and duration is established. Amplitude and/or duration of the reversed voltage are adjusted in dependence on the pulse frequency for the established optimal combination of frequency, charge and duration.
