Title: Roller reefing system for sails and the like
Inventor: STEVENSON WILLIAM H IV
IPC: B63H9/10
Filed: 1987-07-15
Granted: 1992-07-28
Abstract: ABSTRACT The edge of a cambered flexible sheet to be rolled for flattening, usually the luff of a marine sail, is provided with a first securing means which extends along and is attached to only a predetermined intermediate portion of the edge to be rolled and which is employed to connect that edge portion to the stay or other rotatable member about which rolling is to occur.  The same edge of the sheet is also provided with a second securing means comprising flexible means which is attached to the sail and surrounds or embraces the rotatable member in such fashion that, before rolling of the flexible sheet on the rotatable member, and also during that early state of rolling when only the intermediate portion of the edge is rolled, the second securing means supports the edge of the sheet in proper relation to the rotatable member. The second securing means can extend continuously along substantially the entire edge of the sheet to be rolled.  The flexible means of the second securing means surrounds the rotatable member in such a fashion that, before the rotatable member is turned, the rotatable member is free to turn relative to the second securing means.

Title: Apparatus for particle determination in liquid metals
Inventor: HACHEY RAYNALD
IPC: G01N15/12
Filed: 1989-02-03
Granted: 1993-03-30
Abstract: ABSTRACT OF THE DISCLOSURE          The invention relates to apparatus as disclosed for example in U.S. Patents Nos. 4,555,662 and 4,600,880 for on-line particle determination in molten metals, wherein a sample of the molten metal is drawn by a vacuum through a calibrated passage in the side-wall of a heat-resistant tube while a current is established through the passage between two electrodes on either side thereof.  The passage of non-conducting particles through the orifice produces pulses whose magnitude and rate indicate respectively their size and the number of particles per unit volume.  The electrodes and their leads form an interference-receiving antenna so that the wanted test signal, whose signal/noise ratio is inherently low, is subject to interference from neighbouring sources, such as motors, fluorescent lamps and particularly induction furnaces.  The invention provides for the production of a cancellation signal to reduce the unwanted interference component in the test signal by means of a cancellation antenna sufficiently close to the detector electrodes to receive substantially the same signal, the antenna either feeding the cancellation signal to a differential amplifier also fed with the wanted signal, or being connected in series with the interference antenna.  The cancellation antenna can comprise a loop mounted on the head that supports the two electrodes.

Granted: 1995-03-07
Abstract: A noise blanker is disclosed which blanks out impulse noise emanating from the alternator, ignition systems of motor vehicles, and other sources.  This is accomplished by delaying an input IF signal while generating a blanking gate pulse occurring at the same time as the noise pulses.  These blanking pulses are then used to turn off the delayed IF signal precisely where the noise occurs, resulting in noise-free audio reception.  The noise blanker operates to detect noise pulses by detecting the leading edge of any narrow pulse which is received at the front end of the receiver and is reflected in the IF input signal.  At the same time, by virtue of the operation of an AGC amplifier the noise blanker's vulnerability to interference or capture by continuous-wave signals is reduced.

Title: Germanium channel silicon mosfet
Inventor: SOLOMON PAUL M
IPC: H01L29/78
Filed: 1989-09-14
Granted: 1992-04-07
Abstract: GERMANIUM CHANNEL SILICON MOSFET   ABSTRACT OF THE INVENTION          An alloy layer comprising germanium and silicon is grown on top of a silicon substrate.  The alloy layer is kept thin enough for proper pseudo-morphic, dislocation free growth.  A layer of silicon is applied to the alloy layer.  The initial silicon layer is from two to three times as thick as the alloy layer.  Approximately the upper two-thirds of the silicon layer is oxidized, either thermally, anodically or by plasma anodization.  The silicon layer that remains between the silicon dioxide and the alloy layer is kept thin enough so that a parasitic channel does not form on the interface between the silicon and the silicon dioxide.  The germanium alloyed channel is thus suitably bounded by silicon crystalline structures on both of the channel layer surfaces.  The barrier heights between silicon dioxide and silicon are very large thus providing good carrier confinement.  A suitably applied voltage will result in a region of high mobility charge carriers at the interface between the alloy layer and the upper silicon layer.
