Date Apr. 20, 1989.A gripping and rotating tong device for handling drill rods, drill bits and other corresponding, at least partially rod-like pieces. The tong device comprises a housing fastened to a movable transfer device, the housing having an axial hole and a radial aperture for taking the piece to be handled from outside the housing to inside it, and in the housing it has grippers which grip the workpiece introduced into the housing, and parts for rotating the grippers. The grippers include at least two locking ring gears which rest in bearings rotatably in relation to the housing, at least one of them having cogging on the outer periphery and each having a notch extending to the center, along which notch the workpiece can pass to the center of the ring gears and away from them. The rotating of the ring gears is effected by at least one gear, the workpiece centered with the ring gears rotating together with them. The centering and/or releasing of the workpiece is effected by a limited turning of one ring gear in relation to the other ring gear, produced by the starting, ending or changing of direction of the rotation.

Abstract: A phase-locked loop is formed by a series circuit of a counter, a register, an arithmetic unit, a low-pass filter, a PI-filter, and a voltage-controlled oscillator. The digital, internal clock signals generated by the oscillator are counted in a counter and are transferred into the register and stored as a current counter reading at points in time determined by time interval clock signals. For example, the time interval clock signals are acquired from reference clock signals by means of a divider and exhibit a lower frequency than the internal clock signals. A drive signal in digital form is determined in the arithmetic unit on the basis of the current counter reading, on the counter reading of the preceding evaluation interval, and on a rated value. This drive signal proceeds via a digital low-pass filter, PI-filter, and D/A converter to the control input of the oscillator, and controls the latter such that the internal clock signals coincide in phase with the reference clock signals.

Date Jan. 26, 1989.The invention concerns a method of constructing a heat exchanger as well as a heat exchanger constructed in accordance with said method. The method comprises piling of essentially similar corrugated thermal transmission plates to cover each other and connecting the spaces between the plates from their edges to inlet and outlet conduits for the mediums participating in thermal transmission so that through every second space between the plates is passed a flow of heat giving medium and through every second space between the plates a flow of heat receiving medium. Essential to the present invention is that the pressure losses of flows and the thermal transmission coefficient of the exchanger are established by piling the thermal transmission plates one over another so that the grooves in different plates are placed at a selected angle with each other. To make this possible the invention uses essentially circular thermal transmission plates or regular polygonal thermal transmission plates in which the direction of the grooves is such that the grooves in plates piled on top of each other may cross selectively at least in two different angles with each other.

Abstract: In a process for the manufacture of copper arsenate, an arsenic-containing material is subjected to an oxidative pressure  leach  with  sodium  hydroxide  forming  a  leach solution   containing sodium arsenate.   Sodium arsenate solution is mixed with a solution of copper sulfate for the formation of a   copper and arsenic-containing solution without the precipitation of copper arsenate.  The copper and     arsenic-containing  solution  is  treated  for  the precipitation  of copper arsenate with formation of sodium sulfate solution.  At least one of the sodium arsenate-containing solution and the sodium sulfate solution  is subjected  to  electrolysis  with membranes  for  at  least partial  conversion  to  arsenic acid  and  sulfuric  acid, respectively, and sodium hydroxide.  The generated sodium hydroxide is used in the process, the sulfuric acid may be a by-product or is recycled for use in the preparation of copper  sulfate  solution,  and  the arsenic acid  is  used instead of sodium arsenate in the formation of the copper and arsenic-containing solution.

Title: Dental floss holder
Inventor: TARRSON EMANUEL B

Granted: 1994-05-10
Abstract: ABSTRACT OF THE DISCLOSURE    A dental floss holder is in the form of a box with a drawer in it.  The bottom of the drawer includes a hub which is spring biased to push a bobbin mounted thereon toward an opposite side of the box.  The bias is such that the bobbin drags with a predetermined force on an opposite side of the box to maintain tension in the floss.  A result is that the bobbin does not unwind while in the holder, thereby precluding a snarled floss line.  Also, the tension gives a smooth "pull" which adds a "feel" of quality to the floss.  The "feel" does not change as the diameter of the bobbin changes with either an exhaustion of floss or changes in the diameter of a full bobbin.  The hub is mounted on a dome having sides with a shape which guides and directs any floss falling off the bobbin back onto it.
