Title: Modulated plasma glow discharge treatments for making superhydrophobic substrates
Inventor: PALUMBO GIANFRANCO
IPC: E03D13/00
Filed: 1999-09-07
Abstract: The present invention deals with a method of treating polymeric or non polymeric articles for making their surface superhydrophobic, i.e.  characterized by static water contact angle (WCA) values higher than about 120~, preferably higher than 130~, more preferably higher than 150~. The method consists of a modulated glow discharge plasma treatment (1) performed with a fluorocarbon gas or vapor compound fed in a properly configured reactor vessel where the substrates are positioned. The plasma process deposits a continuous, fluorocarbon thin film with superhydrophobic surface characteristics, tightly bound to the substrate. The substrates of interest for the present invention may include a wide range of materials in form of webs, tapes, films, powders, granules, woven and non-woven layers; substrates can be porous or non-porous, molded or shaped, rigid or flexible, made of polymers, textiles, papers, cellulose derivatives, biodegradable materials, metals, ceramics, semiconductors, and other inorganic or organic materials.  Preferably, the substrate is formed into a desired shape or configuration, depending on its intended use, before being subjected to the treatment object of this invention. When organic synthetic resins are chosen, such substrate materials could be fabricated from polyethylene, polyacrylics, polypropylene, polyvinyl chloride, polyamides, polystyrene, polyurethanes, polyfluorocarbons, polyesters, silicon rubber, hydrocarbon rubbers, polycarbonates and other synthetic polymers. A particularly preferred polymeric substrate is polyethylene or polypropylene.

Title: Hydrocarbon cracking process and device using two successive reaction chambers
Inventor: ESPEILLAC MARCELLIN
IPC: C10G11/18
Filed: 2001-07-03
Abstract: The effluents from each chamber are fractionated in a separate part of the same fractionating column (12) which is partially divided and at least one resulting section (13,44a) from the separate fractionating is totally or partially reinjected into the other chamber. Hydrocarbon cracking in a fluidized bed reactor in which the heat bearing particles, which are also catalytic, circulate in two successive reaction chambers (1,16) in each of which they are put in contact with at least one section of hydrocarbons. The reaction effluents from each chamber are sent to the same fractionating unit. The hydrocarbons injected into the first reaction chamber spend less time there than the hydrocarbons injected into the second reaction chamber, with the time in the first chamber being 0.05 to 5 seconds, preferably 0.1 to 1 second and the time in the second chamber being 0.1 to 10 seconds, preferably 0.4 to 5 seconds. The flow through the first chamber is essentially downwards and that in the second is essentially upwards. In the partially divided fractionating column, the heavier effluents from each chamber are fractionated separately whilst the lighter effluents are combined. The section which is reinjected is a slurry or heavy distillate containing HCO and/or a diesel section containing LCO. The heavy effluents from the first chamber are reinjected into the second. Alternatively, the lighter effluents are fractionated separately and the heavy effluents are combined, with the petrol section from the second chamber reinjected into the first. The reinjected fraction can be mixed with other fractions and/or undergo intermediate treatments before reinjection, such as hydrogenation, hydrodearomatization, hydrodesulfurization or hydrodenitrogenation. Upstream of the second chamber particles are injected both from the first chamber and from a regenerator. Device to carry out this process, comprising a partially divided fractionating column with a zone containing two separate fractionating compartments (38,39) and a common compartment (41). This divided zone can be at the top or bottom of the column and the means of division is a flat or cylindrical vertical wall.

Abstract: The invention is related to signaling in cellular telecommunication systems, namely to reduction of resources used by signaling. According to the invention, a list of neighbor cell information is communicated to a mobile static in compressed form. Preferably, the neighbor cell information list is transmitted in such a way, that a table reciting parameter values in use by the neighboring cells, and for each of these cells, each value listed in the table is represented by a pointer such as an index to the table. In this way, same parameter values do not need to be repeated for each cell using the same values. The neighbor cell information list can be further compressed by expressing a first frequency parameter value in the normal way, but expressing further frequency parameter values relative to the first, or as in a further embodiment, relative to the previous frequency parameter value. Such ways of representing frequency values allow the use of fewer bits to represent the frequency values.

Inventor: HADAR RAMI
IPC: H04L1/00
Filed: 2000-07-28
Abstract: A method of assigning downlink time slots to receive units where the units may generate data using different modulation schemes. The method preferably assigns the downlink time slots as a function of the complexity of modulation schemes employed by the units. Further, the method preferably assigns the time slots from the least complex modulation scheme to the most complex scheme. The method may further assign uplink time slots to transmit units where the transmit units may generate data using different modulation schemes. The method preferably assigns the uplink time slots as a function of the complexity of modulation schemes employed by the uplink units. Further, the method preferably assigns the uplink time slots from the least complex modulation scheme to the most complex scheme. In other embodiments, the downlink time slots are assigned as a function of the bit per symbol rate employed by the receive units, preferably from the lowest bit per symbol rate to the highest bit per symbol rate. Further, the uplink time slots are assigned as a function of the bit per symbol rate employed by the transmit units, preferably from the lowest bit per symbol rate to the highest bit per symbol rate. The present invention is also a method of simplifying the encoding of a predetermined number of bits of data into frames. The method adds error coding bits so that a ratio of the frame length times the baud rate of the frame times the bit packing ratio of the data divided the total bits of data is always an integer. The method may also convolutionally encode the bits of data so that the same equation is also always an integer. The present invention is also a method of updating the weights of a FIR filter where the filter processes symbols having variable modulation rates. When the modulation rate of the incoming symbols changes, the weights corresponding to the first symbol having the new modulation rate are changed based as the symbol propagates through the filter.

Title: Adjustable-backset latch system for locksets, and method
Inventor: WINARDI MICHAEL
IPC: E05B55/00
Filed: 2000-08-11
Abstract: An adjustable-backset latch system for a lockset includes three main subsystems; a bolt retraction system (12), a backset-adjustment system (14), and a deadlatching system (16). By virtue of thesimplicity of the design of the backset adjustment subsystem, theuser can change the backset from 2-3/8" to 2-3/4", and vice-versawith one hand. A pin (76) is simply moved through a "U"-shaped slot (68) formed in a housing (34) and the housing and bolt actuation components are extended simultaneously by the desired backset increment. The bolt retraction system of the present invention uses a cam (40) in which the distance from a point (42) about whichthe cam rotates and the end of the cam, and the distance to a smaller cam pin (46), are selected to multiply the relatively small angular distance transversed during a half-round rotation of the knob or handle into the desired retraction distance of a main bolt. The deadlatching system uses two springs (52, 54), one of which not only biases an auxiliary bolt (20) to its extended position, but also biases a deadlocking dog (118) so as to pivot into a blocking position preventing the main bolt from being retracted completely, in the event an intruder attempts to move the bolt.

IPC: A61P31/04
Filed: 1999-10-22
Abstract: A method of preventing necrotizing tissue injury in gastro-intestinal tract comprising orally administering glutamine is described. Glutamine protects tissues along the gastro-intestinal tract by blocking translocation of bacterial agents (such as gram (-) bacteria), other infectious agents, toxins, chemicals, and injurious substances. The intraluminal/apical presence of the glutamine optimizes mucosal defense and increases nutrient absorption.  Glutamine may be administered to pre-term or full-term infants, children and adults. Enteral glutamine is useful in treating neonatal necrotizing enterocolitis for reducing inflammation caused by bacterial translocation and injury. Oral glutamine is also useful in treating gastro-intestinal dysfunctions. When glutamine is orally administered it coats gastro-intestinal mucosa thereby treating infectious and/or inflammatory conditions of the gastro-intestinal tract. It is useful in treating pathologic conditions with lowered transepithelial electrical resistance (TEER) by acting as a curative agent. Glutamine may be provided in any form such as powder, capsules, acid-resistant slow-release microcapsules, in a reconstituted liquid or the like.  Glutamine may also be orally administered in a mixture. Other drugs for treatment may also be administered with the glutamine. Glutamine is administrable via naso-gastric tube, especially for preterm infants.
