Title: Reactor and use thereof
Inventor: DEELEN WILLEM JOHANNES
IPC: C10G45/00
Filed: 1995-04-27
Abstract: Reactor comprising a normally vertically extending vessel containing (a) at least one inlet for gas and/or liquid, (b) at least one outlet for reactor effluent, and (c) at least one bed of solid material, wherein each bed of solid material rests upon a support layer which is horizontally fixed in the vessel, said support layer comprising at least one opening closed by a breakplate during normal operation.      During normal operation the openings in the support layers are closed by a breakplate, so that bypass of gas and liquid to the consecutive bed is avoided. The reactor is unloaded by cutting the caked catalyst into smaller pieces and breaking the breakplates. The catalyst pieces can then be removed from the reactor via the openings obtained.      The reactor is particularly suitable for use in the hydrotreatment of hydrocarbon oils.

Title: Manufacture of materials and work-pieces having fine grain for components in nuclear plant applicantions
Inventor: ALTER DIETRICH
IPC: C21D8/00
Filed: 1992-12-18
Abstract: Austenitic steel for components intended to be used in radiation zones of nuclear reactors is largely resistant to irradiation-inducing stress crack cor-rosion if its silicon, phosphorus and sulfur content is reduced in relation to standard commercial steel quantities and its grain structule has an average glain diameter under approximately 20 µm. The optimum grain structure is achieved when annealing is avoided at temperatures over 950 °C. When niobium is added as a carbide former leading to a fine dispersion of car-bides, an increased resistance to irra-diation ioduced stress corrosion crack-ing is still achievable when anneal-ing temperature under approximately 1075 °C are used.

Title: Method of operation of a radio system with dormant mode
Inventor: SERFATY SALOMON
IPC: H04B1/16
Filed: 1995-05-31
Abstract: A method is described of operating a radio system having a transmitter unit (10) and a receiver unit (11). At the transmitter unit, at least a portion (50) of an address is transmitted repeatedly for a predetermined period of time (T w), followed by a message. The receiver unit switches from a dormant, low power mode to a receive mode after a period of time in the dormant mode not exceeding the predetermined period of time (T w). In the receive mode address information is received and compared bit by bit with a predetermined address stored at the receiver unit. The receiver reverts to the dormant mode as soon as a negative comparison is made, to a predetermined degree of non-correlation, between address information received and the predetermined address, thereby saving battery power.

Title: Immunogenic lhrh peptide constructs and synthetic universal immune stimulators for vaccines
Inventor: LADD ANNA
IPC: A61P15/00
Filed: 1994-04-28
Abstract: This invention relates to immunogenic luteinizing hormone releasing hormone (LHRH) peptides that lead to suppression of LHRH  activity in males or females. When male rats are immunized with these peptides, serum testosterone drops and androgen-dependent organs atrophy significantly. These peptides are useful for inducing infertility and for treating prostatic hyperplasia, androgen-dependent carcinoma, prostatic carcinoma and testicular carcinoma in males. In females, the peptides are useful for treating endometriosis, benign uterine tumors, recurrent functional ovarian cysts and (severe) premenstrual syndrome as well as prevention or treatment of estrogen-dependent breast cancer. The subject peptides contain a helper T cell epitope and have LHRH at the C terminus. The helper T cell epitope aids in stimulating the immune response against LHRH. The peptides, optionally contain an invasin domain which acts as a general immune stimulator. In another aspect this invention relates to immunogenic synthetic peptides having an invasin domain, a helper T cell epitope and a peptide hapten and methods of using these peptides to treat disease or provide protective immunity. The peptide haptens of the invention include LHRH, amylin, gastrin, gastrin releasing peptide, IgE CH4 peptide, Chlamydia MOMP peptides, HIV V3 peptides and Plasmodium berghei.

Title: Food Processing Effluent Rendering Process and Apparatus
Inventor: O'CARROLL LYNDA C
IPC: C02F1/56
Filed: 1995-10-27
Abstract: A process for the rendering of an effluent stream from a food processing plant,  in which the effluent has or is made to have an acidic pH and carries  proteinaceous  material.  The  effluent  is contacted with an inorganic coagulant  (clay)  that together with the acidic pH effectively neutralises ionic charges on the proteinaceous material to cause the  proteinaceous  material  to precipitate  out  of solution.  The effluent stream is contacted with a biologically   derived   polymeric   flocculant   to facilitate settling of the precipitated proteinaceous material as flocs. The inorganic coagulant is present in an amount by weight of at least 1.5 times or 2.5 times the amount by weight of polymeric flocculant. Flocs are removed from the effluent stream to thereby render the effluent stream. A biologically derived co-flocculant is added to the effluent stream after contact with the effluent stream by coagulant and flocculant.  Insoluble salts of alkaline earth metals are added to the effluent stream after contact with the effluent stream by coagulant and flocculant. The process may be applied to unit operations within the food processing plant. Apparatus for floc treatment include a mixing and acidity setting tank, a conical settling vessel with baffled outlet,  a floc  seed supply for effluent entering the settling vessel, an effluent diffuser at the inlet to the settling vessel and an agitator set to delay agitation until floc settles in the settling vessel.

Abstract: There is disclosed a lure retriever for retrieving a lure on a fishing line, comprising a body, a lure release member mounted to the body and for releasing a snagged lure, and a friction drive system means for engagement with the fishing line to advance the lure release member to a snagged lure. This has the advantage of preventing disengagement of the fishing line with the lure which would otherwise occur when the user simply pulls the fishing line.   In addition to the foregoing advantage, the friction drive system provided on the apparatus, permits the apparatus to be drivable in a variety of either positive or negative inclinations.  This circumvents the  difficulties  previously  encountered in  prior  art arrangements.

Title: Process and apparatus for reducing bound water content of solid carboniferous materials
Inventor: BIELFELDT FRIEDRICH B
IPC: B30B9/24
Filed: 1996-09-17
Abstract: The invention relates to a process, a device and a press for reducing the water content, bound by capillarity in fibre cells, of pulverized solid carboniferous materials and/or sludges, especially raw lignite.  For large-scale industrial use of raw lignite by means of thermomechanical dewatering with better overall efficiency during flow throughput in large power plants, the process of the invention consists of a combination of the following process stages: a) an feed material preheated to approximately 60° Celsius is used, which at the beginning of the operating cycle is steamed from both flat sides in an essentially vapourtight pressure chamber, closed off and preheated to  100° Celsius, with water vapour superheated to  150° Celsius, while b)  the compressive pressure on the feed material  the pressure in the feed material due to bulk density, is at the maximum approximately equivalent to the introduced steam pressure of 5 bar to 8 bar, and c)  after a temperature of approximately 125° Celsius is reached in the feed material, the injection steaming is terminated and, depending on the granular size of the feed material, a high mechanical, specific pressure in the press up to a maximum of 75 bar is used for reduction to a residual water content of up to 20 percent by weight.
