Title: Routing logic means for a communication switching element
Inventor: HENRION MICHEL ANDRE ROBERT
IPC: H04L12/56
Filed: 1991-03-11
Granted: 1999-04-06
Abstract: Routing logic means (RL) for a communication switching element (ISE) of a self- routing multi- stage switching network and able to transfer cells or packets of information from any of its inlets (I1-32) to any of its outlets (O1-32).  The outlets of the switching element are arranged in routing groups containing one or more of them and of which the identity is derived by the routing logic means from an output- port- address (OPA) identifying an output of the switching network and contained in the self-routing- tag (SRT) associated to the cell.  This cell is then transferred to one of the outlets belonging to the selected routing group.       The routing logic means (RL) are also able to control the transfer of a cell through the switching element according to the execution of a predetermined routing function selected amongst a plurality of routing functions (RS, DI, MC, BH, IS).  This routing function to be executed is selected by the routing logic means according to a routing- control- code (RCC) also contained in the self- routing- tag (SRT) and each value thereof identifies a specific transfer pattern constituted by a predetermined sequence of routing functions to be executed in the switching elements (ISE) through the switching network (SN).

Granted: 1995-08-29
Abstract: In a process and a device for fitting at least one electrically conducting detector wire in a plastic cable duct which can be laid in the ground so that said detector wire is embedded and surrounded on all sides, it is suggested to make a wire-receiving groove in the duct-sheath, then to lay the wire in the receiving groove, and finally to lead a separate, softened filler material into the receiving groove and weld it to the duct-sheath. In this way, the detector wire is reliably embedded in the duct-sheath.

Title: C-beam force sensor
Inventor: VANGERPEN HARLAN WELBERT
IPC: G01L1/04
Filed: 1991-09-24
Granted: 1996-07-30
Abstract: A draft force sensor includes a generally C-shaped member formed by a beam and a pair of lugs which both project to one side of the beam.  Coupling holes are located in each lug and the centers of the holes are off-set from the centerline of the beam.  One end of a flexible strap is fixed to one lug and the other end of the flexible strap is adjustably attached to the other lug.  Alternatively, both ends of the flexible strap may be coupled to the lugs by adjustable support devices which are pivotally connected to the beam.  The strap is curved and concave in a direction facing the beam and is biassed to urge the supports and the lugs away from each other.  A displacement transducer is mounted between the beam and the central portion of the strap.  The displacement transducer senses the change of distance from the beam to the "arch" of the strap and generates an electrical signal indicative of the force on the ends of the C-shaped member.

Abstract: The  scroll  wrap  portion  of  a  centrifugal  blower housing is joined to the opposite scroll side portions thereof using uniquely configured double tab locking joints spaced apart around the peripheries of the scroll side portions.  To form the joints, spaced series of tabs formed along the curved side edges of the scroll wrap are extended outwardly through corresponding peripheral slots in the scroll sides, and are brought into side-by-side adjacency with outwardly projecting tabs formed on the scroll sides at their peripheral slots. Supported series of forming tools positioned outwardly of the opposite scroll sides are forced inwardly against the side-by-side tab pairs in a manner tightly rolling them together to simultaneously form all of the double tab locking joints around both of the scroll  side  peripheries.    The  rolled  joints  mutually interlock  portions  of  each  of  the  scroll  sides  with adjacent  portions of  the  scroll  wrap  in  a  manner essentially preventing any appreciably relative movement between the scroll wrap and side portions at their joined areas.

Title: Method and circuit for detecting burst signal
Inventor: ONO MITSUHIRO
IPC: H04L27/00
Filed: 1992-10-09
Granted: 1999-01-19
Abstract: A phase angle ~ of a received signal is calculated according to a formula ~ = tan-1 (Q/I), where I and Q are magnitudes of baseband signals obtained by quadrature detection of the received signal, and an angular velocity .DELTA.~ of the phase angle ~ is calculated.  A variance parameter .SIGMA.~ is calculated from a deviation ~ = .DELTA.~ - .DELTA.~, where .DELTA.~ is a moving average of the .DELTA.~, andthe variance parameter .SIGMA.~  thus calculated is compared with a reference value to decide existence of a burst signal.  Since the decision is performed essentially not based on an amplitude of the received signal but based on a phase of the received signal, fluctuation of the amplitude of the received signal does not affect the decision.

Granted: 2002-12-03
Abstract: A composition of matter which comprises Tumor Necrosis Factor (TNF) and Interleukin-4 (IL-4) has been disclosed, This composition inhibited the growth of human breast cancer cells, human vulvar carcinoma cells and human histiocytic lymphoma cells a dose-dependent manner. The growth characteristics of human breast cancer cells were minimally affected when exposed to TNF or IL-4 alone. However, the combination of these two cytokines together inhibited the growth of these cells in a dose-de-pendent manner. Additionally, interferon-gamma (IFN-g) caused a further potentiation of the antiproliferative effects of the TNF and IL-4 composition.

Abstract: A protective passive oxide layer is formed on the inner surfaces of metal heat pipes or tubes including their end caps, welds and accompanying hardware through the use of an oxygen encapsulation method.   After cleaning the tube and its accompanying parts, the tube is reassembled and existing gases within the tube are removed thereby creating a vacuum inside the tube.  The tube is then filled with pure oxygen and sealed.  After the oxygen is sealed within the tube, the sealed tube is heated thereby forming a passive oxide layer, such as magnetite (Fe3O4) on the inner surface of the tube.

Abstract: A dispensing nozzle is provided with uniform, very-small diameter orifices of 0.001 to 0.015 inch (25 to 400 microns) by slotting at least one of two preferably- conical abutting faces between relatively movable parts defining a nozzle wall. The orifices can be formed by cutting with a broach to form an array of slots in a conical plug structure that fits against a complementary conical seat. Micro-orifices are defined between the conical structure and seat, preferably with an internal diameter of about 0.004 to 0.007 inch (100 to 170 microns) for dispensing uniform small droplets of thin oil/water invert emulsions. The conical structure can be liftable from the seat for flushing the slots by use of a spring mount, whereby increasing the dispensing pressure lifts the plug and flushes the slots. A filter screen reduces the tendency of the nozzle to clog. The dispensing nozzle provides an efficient and cost effective means to form uniform small droplets, enabling ultra low volume spraying of agricultural active agents in thin invert emulsions, for example obtaining effective applications at one pint to one quart per acre.
