Inventor: CUYPERS MARTINUS H
IPC: B23F15/06
Filed: 1990-09-28
Abstract: A cutter for producing face gears, comprising a disc-shaped cutter body with cutting teeth fitted on periphery. The cutting edge of each cutting tooth lies in a surface of revolution which is produced by turning an imaginary gear wheel of infinitely low thickness about the axis of the cutter and simultaneously about its own axis.      Each cutting tooth of the cutter is of such a shape that the cutting tooth is re-grindable, without the shape of the cutting edge of the cutting tooth changing as a result.      This is achieved through the fact that the profile of each cutting tooth shifts in planes from the cutting edge of the cutting tooth to the rear side thereof in the direction of the axis of the cutter.

Title: Strain-gauge mounting for force-sensing touch-screen
Inventor: GARWIN RICHARD L
IPC: G06F3/041
Filed: 1992-06-29
Abstract: STRAIN-GAUGE MOUNTING FOR FORCE-SENSING TOUCH-SCREEN            ABSTRACT OF THE DISCLOSURE      A mounting for supporting a portion of a touch-panel or display and for measuring the force at the mounting due to a force applied to the touch-panel is described incorporating a touch-panel or display, a frame, a spring or  beam  having  one  end  rigidly  attached  to  the touch-panel or to the frame with the other end free to rotate and attached to a torsion bar, wire, or strap.

Abstract: Known methods of transferring between centres the handling of an active connection between a user and a mobile terminal in a telecommunication system designed for mobile communication generally have the disadvantage that the routing obtained is inefficient. By investigating botha first route between a first switching centre and the user and a second route between a second switching centre and the user for common centres which are able to handle call control and connection control separately, of which the common centre situated nearest the first switching centre is designated as central intelligence point or, if the latter is not found, by designating the centre situated nearest the user as central intelligence point and then setting up a connection between a central intelligence point found in this way and the second switching centre, the most efficient routing is obtained.

Title: Cmos strobed comparator
Inventor: VINCELETTE SCOTT
IPC: H03K5/24
Filed: 1992-04-03
Abstract: An all CMOS voltage comparator circuit which incorporates a strobed latch. A strobe signal precharges the entire circuit to a known state which is independent of the input voltages and in which substantially no static current is drawn. Under static conditions after the circuit has been strobed, the source-coupled pair is virtually disconnected from the supply voltage(s) and draws almost no current, as well. then the circuit is strobed, a source-coupled FET pair amplifies the differential input signal, with positive feedback provided through a pair of cross-coupled PMOS load transistors, as well as cross-coupled NMOS cascode transistors. The source-coupled pair feeds a pair of output buffers, or drivers, whose FETs are sized such that a "low" voltage level is generated on both outputs until the source-coupled pair resolves the input voltage difference (i.e., the differential input voltage exceeds the switching threshold). At that time, the outputs become complementary digital levels and are usable.

The operator includes a drive gear secured to a base on the frame, a sun gear pivotable about the axis on the base and drivably engaging the drive gear, a primary arm with a planetary gear rotational-ly attached thereon and drivably engaging the sun gear, a secondary arm pivotally mounted about a second axis on the base, and a pair of drive links pivotally intercon-nected between the planetary gear and the secondary arm. A bracket is fixed to the sash side opposite the one sash side, a first connecting arm is pivotally connected at one end to the primary arm and at the other end to the bracket, and a second con-necting arm is pivotally connected at one end to the secondary arm and at the other end to the bracket, where all of the arms cooperate to move the sash bottom sidetoward and away from the frame to control opening and closing of the sash in response to rotation of the drive gear. The base includes a fixed primary arm stop which engages the primary arm to prevent lateral shifting of the window when thesash is closed against the frame. The base also includes a fixed secondary arm stop which engages the secondary arm to prevent lateral shifting of the sash during initial opening of the sash from a position closed against the frame.

Title: Differential screening protocol that allows the detection of marginally induced or repressed mrnas
Inventor: LEMKE STEPHANIE J
IPC: C12Q1/68
Filed: 1993-02-08
Abstract: ABSTRACT           The invention differential screening technique, single plate one transfer (SPOT), which allows for the sensitive and reliable detection of mRNAs induced or repressed only 2 to 3 fold or less with respect to background.  The basis for this technique is to symmetrically spot in quadruplicate or more on a single plate, a large number of potentially positive plaques obtained from  a primary, conventional screen.  Only one lift is made from this plate in order that there will be minimal variability in DNA transfer.  This filter is cut into symmetrical sections such that DNA from all plaques are multiply represented on each section.  The sections are next hybridized with different probes. Since each section contains an approximately identical amount of DNA per plaque, one may accurately detect mRNAs that are induced or repressed only slightly above background.

Title: Continuous ore feeder for soderberg aluminum reduction cells
Inventor: NORDQUIST JAMES H
IPC: B25D17/28
Filed: 1991-10-04
Abstract: Improved methods and apparatus for carrying out the methods are disclosed for feeding alumina into a Soderberg type aluminum reduction cell (10), so as to maximize efficiency of the cell. The apparatus includes a continuous point feeder assembly (12) connected to the cell structure over an exposed peripheral portion of the cryolite bath. The feeder assembly includes an alumina feed hopper (40) and a pair of vertically disposed feeding bins (56). Each feeding bin receives alumina from the hopper. A piston and cylinder assembly (46) is connected to the feeder assembly and arranged to drive a crust breaking member (44) down through bath crust (17) to form a temporary opening. The crust breaking member includes discharge port covers (62) which cover the lower ends of the feeding bins when the crust breaking member is retracted, and uncover the lower ends when the crust breaking member is extended, thereby opening feed discharge ports (60) and allowing a predetermined quantity of alumina to flow through the opening and into the bath. The point feeder assembly is actuated at predetermined, frequent intervals and the hopper refilled as necessary.  Occasionally, the peripheral crust is broken by an elongate horizontal breaker bar (34) and a supplemental charge of alumina is forced into the bath to achieve maximum concentration.
