Title: Homogeneous-heterogeneous catalyst system for polyolefins
Inventor: SHAMSHOUM EDWAR SHOUKRI
IPC: C08F4/60
Filed: 1992-09-08
Granted: 2003-04-15
Abstract: This invention concerns a catalyst system comprising at least one homogeneous catalyst and at least one heterogeneous catalyst, specifically, a metallocene catalyst and a conventional Ziegler-Natta catalyst, respectively. This invention is useful in the polymerization of any polymer in which separate polymerizations with a homogeneous catalyst and with a heterogeneous catalyst are possible, but preferably, polymerization of olefins, more preferably, a-olefins, and, most preferably, propylene. This invention provides a catalyst system which facilitates use of a homogeneous catalyst but eliminates the disadvantages of such a system. This invention produces a polymer with molecular weight distribution (MWD) as broad or broader than the MWD of the heterogeneous catalyst alone. Hydrogen can be used to control molecular weight distribution of a polymer produced with this invention.

Title: Gps tracking system
Inventor: BROWN ALISON K
IPC: G01S5/00
Filed: 1992-11-19
Granted: 2003-11-18
Abstract: A low cost tracking system employing satellites of the global positioning system (GPS) is suitable for applications involving radiosondes, sonobuoys, and other objects. The tracking system includes a sensor mounted on each object which digitally samples the GPS satellite signals and records them in a data buffer. The digital samples are then transmitted, at a rate lower than that at which the GPS satellite signals were sampled, over a data telemetry link, interleaved with other telemetry data from the object. The GPS data is processed in a data processing workstation where the position and velocity of the sensor, at the time the data was sampled, is computed. The data buffer in the sensor is periodically refreshed, and the workstation periodically computes the new position and velocity of the sensor. Differential corrections are also provided at the workstation to aid in signal acquisition and to increase the precision of the position fix.

Title: Cmos strobed comparator
Inventor: VINCELETTE SCOTT
IPC: H03K3/356
Filed: 1992-04-03
Granted: 2002-06-11
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.

Title: Steel mesh heating system with reduced magnetic field
Inventor: WILDI THEODORE
IPC: H05B3/40
Filed: 1994-12-22
Granted: 1998-10-13
Abstract: A heating system using steel mesh or steel rods, such as are used for reinforcing concrete.  The magnetic field associated with such a system can be significantly reduced by causing a current to flow in a set of conductors that are superposed on, and in close proximity to, the current-carrying wires of the steel mesh or steel rods. The total current in the conductors is essentially equal to and 180 degrees out of phase with the  total  current  in  the  wires.    The  significant reduction of the magnetic field improves the power factor of  the  heating  system,  eliminates  the  flicker  and distortion  of  the  image  on  sensitive  computer  and television and other cathode ray tube  screens,  and diminishes  possible  biological  effects  on  living organisms.
