Title: Digital communications equipment using differential quaternary frequency shift keying
Inventor: SUTTON JEFF REYNOLDS
IPC: H04B1/713
Filed: 1994-10-17
Abstract: A digital radio transceiver uses a differential 4-ary frequency shift keying (D4FSK) modulation scheme to achieve a radio that is low cost, miniaturizable, low in power consumption and high in spectral efficiency. An adaptive digital "slicer" (31) looks at a digitized FM video signal produced in the receiver to determine if the data sent is a 00, 01. 10 or 11. The digitized FM video signal is first processed by a differential decoder (31), the output of which is input to a peak detector. The peak detector outputs a signal upon the occurrence of a three-step transition. Two and three step transition are separately  detected and used to perform digital clock recovery. A carrier detect circuit uses a digital bit filter to produce a carrier detect signal (CD) that is reliable and glitch-free. The digital radio transceiver uses frequency hopping spread spectrum transmission (23). A switchable loop bandwidth frequency synthesizer provides for glitch-free switching between a wide hopping bandwidth and a narrow bandwidth between hops.

Title: Latex with resistance to bacterial growth
Inventor: DUNN EDWIN REED
IPC: C08K3/00
Filed: 1996-05-15
Abstract: The growth of bacteria in latex is an age old problem. To control the growth of bacteria in latex, chemical bactericide are of ten added to latex . This invention discloses a technique for providing latex with resistance to bacterial growth. It is based upon the discovery that ions of a metal from Group Ib of the Periodic Chart, such as copper, silver, or gold, will provide latex with resistance to bacterial growth. The subject invention more specifically discloses a latex which is comprised of (1) a polymer, (2) water, (3) an emulsifier and (4) ions of a metal from Group Ib of the Periodic Chart. In most cases, the metal ions will be present in an amount which is within the range of about 1 ppm to about 50 ppm. As a general rule, silver ions are preferred. By utilizing a combination of standard organic chemical bactericides and Group Ib metal ions, the level of chemical bactericides and metal ions needed to satisfactorily control bacteria growth can be significantly reduced. Such a combination of chemical bactericides and Group Ib metal ions accordingly offers excellent cost advantages and provides treated latex with a high degree of protection against bacterial growth. The present invention further reveals a latex which is comprised of (1) a polymer, (2) water, (3) an emulsifier, (4) ions of a metal from Group Ib of the Periodic Chart and (5) an organic chemical bactericide.

Title: Wood/coal burning heater
Inventor: ROGERS DALE CLAYTON MARK
IPC: F24B5/02
Filed: 1996-07-15
Abstract: A stove primarily for burning wood or coal, but the same principle could also be used on stoves or heaters designed for any other fuel, This stove is equipped with a conventional firebox with an overhead and underneath draft. But the present aparatus is also equipped with a heat exchange area totally encircling the firebox which keeps the firebox itself hotter as the firebox heat doesn't dissipate directly out into the room, Then as the smoke and heat leave the firebox they have to totally encircle it thus traveling a longer distance before leaving the stove and entering the chimney. This results in more heat dissipating out into the room from the same amount of fuel,

Title: Free radical oxidation process and installation for treating liquid effluents contaminated by organic substances
Inventor: GUY CHRISTOPHE
IPC: F23G7/00
Filed: 1996-10-16
Abstract: In  the  process  and  installation  for decontaminating a liquid effluent contaminated by at least one organic substance, a gaseous combustible is burned in a reactor to produce a flame containing hydroxyl free radicals OH° and oxygen O2 and that flame is centered on the geometrical axis of the reactor. A helical flow of liquid effluent is produced on the inner cylindrical wall of the reactor to cause a direct contact between the hydroxyl free radicals and the  organic  substance  contaminating  the  liquid effluent.  By means of the hydroxyl free radicals, the organic substance is oxidized in liquid phase.  The high temperature of the flame enables completion of the oxidation of the organic substance,  in liquid phase, by means of the oxygen O2 present in the flame. At the outlet of the reactor, the liquid and gaseous products  are  separated;  the  liquid  product  is collected while the gaseous product is evacuated.

Title: Methods of identifying patients having an altered immune status
Inventor: OCHOA AUGUSTO C
IPC: G01N33/53
Filed: 1995-07-07
Abstract: Methods of identifying a patient having an altered immune status involve determining an immune status index for the patient and comparing it to the immune status index in healthy individuals. In general, an immune status index is the ratio of the amount of a protein that varies significantly in a patient with an altered immune status to the amount of another protein that is substantially invariant in both healthy and immune-altered individuals. Variable proteins can be TCR subunit proteins, T lymphocyte signal transduction pathway proteins, polynucleotide binding proteins or biological response modifiers (BRM). In addition, the ratio of a TH-1-type BRM to a TH-2-type BRM, the ratio of cytoplasmic to nuclear levels of polynucleotide binding proteins, the pattern of protein binding to an oligonucleotide probe that comprises the protein binding region of a gene for a BRM, or the pattern of distribution of T lymphocytes in a density gradient following density gradient centrifugation are also suitable as an immune status index. The methods are useful in identifying patients exhibiting immunosuppression, hyperimmunity and autoimmunity, as well as in assessing the immune status of a patient undergoing organ transplant.

IPC: B21B15/00
Filed: 1997-02-26
Abstract: In a steel pickling process, especially for stainless steel strip, employing an aqueous hydrochloric acid pickling solution, the Fe(III) ion concentration is maintained at 1-300 g/l, for constant pickling capacity of the solution of pH less than 1, by oxygenation (preferably aeration) to effect re-oxidation of the Fe(II) ions generated during pickling, the redox potential being maintained at a value of 0-800 (preferably 400-600) mV as measured between a Pt electrode and an Ag/AgCl reference electrode in the solution. Also claimed is a continuous rolled steel (especially stainless steel) strip production line employing the above process, in which the strip is subjected to mechanical treatment (e.g. stretch-levelling and/or peening), primary pickling, working (e.g. rolling), annealing, final pickling and finishing (e.g. skin pass rolling), at least one of the pickling operations being carried out by the above process.
Patent CA-2198664-A1 (CA)
Inventor: DURANT RAYMOND J
IPC: B25B27/00
Filed: 1997-02-27
Abstract: An apparatus for quickly and efficiently removing valve packing from a valve of the type having a threaded or non-threaded valve stem. In general, the apparatus includes a sleeve adapted to be positioned about the portion of the valve stem which extends exteriorly of the packing. The sleeve is rotatably connected to a translation mechanism operable in conjunction with the exposed portion of the valve stem. Depending on the type of valve and whether the exposed portion of the valve stem is threaded or smooth and whether or not the valve stem is capable of rotation, the translation mechanism can either be threadingly mated or clamped onto the valve stem to cooperate therewith for translating the sleeve toward or away form the packing. When the translation mechanism is operated, the rotatably connected sleeve is caused to translate along the valve stem. A plurality of curved teeth depend from the sleeve in such a manner that they all curve in the same rotational direction with respect to the sleeve. When the sleeve is rotated in that rotational direction and a downward force on the sleeve is applied by operating the translating mechanism, the teeth are forced to penetrate down and into the packing material. Once embedded, the translation mechanism can be operated in the opposite direction to apply an axial removal force to the sleeve and, hence, the teeth, thereby extracting the valve packing in which the teeth are embedded. Advantageously, since the sleeve is rotatable independently of the translation mechanism, the rotational force on the sleeve can be maintained or furthered to ensure the teeth remain embedded in the valve packing and to provide relative twisting motion between the valve packing and valve packing housing to facilitate removal of the valve packing. The teeth are readily removable and replaceable with different teeth or other implements for performing a variety of functions relating to removal of the valve packing, such as cutting, chiselling gouging, cleaning and polishing.

Title: Intraluminal graft and method for insertion thereof
Inventor: DICKERSON TIMOTHY S
IPC: A61F2/82
Filed: 1995-10-06
Abstract: An intraluminal graft/stent (10) includes a hollow tubular member with inner (13) and outer (14) wall members, defining a cavity (C) in which is positioned a time delay, heat activated material (16) partially filling the cavity. Upon implantation of the graft/stent (10) in the blood vessel to be repaired, the time delay, heat activated material (16) will foam and expand to completely fill the cavity causing the outer wall to sealingly engage the interior wall of the blood vessel. The inner wall, upon expansion, provides a conduit for the flow of blood. Under one embodiment, a flexible support member (22) encircles the outer wall member and, by virtue of its shorter length and smaller cross-sectional size than the outer wall member, causes enlarged cuffs (29) to be formed at opposing ends of the graft/stent upon completion of expansion of the time delay, heat activated material.
