Filed: 1985-03-15
Abstract: A process for the preparation of urea in which a carbamate- and free ammonia-containing urea synthesis solution is formed from carbon dioxide and excess ammonia in a synthesis zone at a pressure of 125-350 bar, at least a portion of the carbamate present in the urea synthesis solution is decomposed in a stripping zone at the pressure of the synthesis zone or at lower pressure by heat supply and countercurrent contact with a stripping gas, the carbamate decomposition products, together with a portion of the excess ammonia and the stripping gas, are removed from the stripping zone as a gas mixture, at least a portion of the gas mixture obtained is condensed in a condensation zone and the stripped urea synthesis solution is processed into a urea solution or solid urea. The process is characterized in that in the condensation zone also at least 30% of the equilibrium amount of urea achievable under the reaction conditions is allowed to form and the carbamate- and urea-containing mixture is supplied to the synthesis zone.

Title: Solution-phase dual hybridization assay for detecting polynucleotide sequences
Inventor: DATTAGUPTA NANIBHUSHAN
IPC: C07H21/00
Filed: 1986-02-21
Abstract: A dual hybridization assay method for detecting the presence of a particular polynucleotide sequence in a test sample wherein hybridization is accomplished in a solution phase. Two soluble polynucleotide probes are employed which hybridize to mutually exclusive portions of the sequence to be detected. The first, or separation, probe comprises a reactive site for a reaction partner, preferably a binding site (e.g., biotin) for a binding substance (e.g., avidin). After hybridization, the resulting solution is contacted with an immobilized form of the reaction partner whereby dual hybrids comprising the sequence to be detected and the detection and separation probes become immobilized. The immobilized fraction is then separated and the detection probe determined in one of the separated fractions. Preferably, the detection probe is labeled such as with a specifically bindable ligand, e.g., biotin or a hapten, and is detectable by binding of a labeled binding partner, e.g., enzyme-labeled avidin or antibody. The assay method has the advantages of a dual hybridization technique plus the kinetic and manipulative advantages of a solution-phase assay.

Title: A process for the production of a member by shaping build-up welding
Inventor: GEISSELER MAX
IPC: G21C19/32
Filed: 1987-03-19
Abstract: Built-up or facing material is melted in an electric arc between a parent member and at least one electrode movable relative to the parent member. As the electrode moves, at least one welding parameter is varied in a predetermined zone of movement in order to form an open channel. After passing this zone, the original welding parameters are restored and a former is placed over the channel to complete the cross-section of the channel. Welding continues until the required wall member has been reached. The former can be subsequently removed by dissolving or decomposition. The open channels may receive neutron-absorbent material where the member is used as a cylindrical storage receptacle for nuclear fuel elements.

IPC: D21F7/08
Filed: 1999-12-14
Abstract: A press fabric for the press section of a paper machine has a base fabric which includes a nonwoven mesh fabric. The base fabric, or a layer thereof, is assembled in integral form using a strip or strips of the nonwoven mesh fabric. The assembly may be effected by spirally winding the nonwoven mesh fabric in a plurality of non-overlapping turns, by abutting each turn of the nonwoven mesh fabric against that previously wound, and by joining each turn of the nonwoven mesh fabric to that previously wound to form an endless loop. Alternatively, a plurality of endless loops of equivalent length are formed from separate strips of nonwoven mesh fabric, and arranged in a side-by-side abutting relationship. The endless loops are then joined, one to the next, to provide a base fabric, or component thereof, in the form of an endless loop. <IMAGE>

Title: Centifrugal separator and rotor therefor
Inventor: SAMWAYS ANDREW
IPC: B04B5/00

Granted: 2009-11-18
Abstract: A rotor (10, Fig 2) for a centrifugal separator (12) for circulated engine lubricant is formed by end walls (44, 46) and radially outer and inner side walls (42, 52) that define a separation and containment region 82. The wall (52) is defined by a tubular tension member (50) that surrounds a rotation axis (30) and extends between and through the end walls to keep them in position. Mounted within first and second ends (72, 74) of the tubular tension member are a first-end closure plug (86) and second-end closure plug (88) respectively. The plug (88) has a passage (90) to admit liquid into the tubular member, but otherwise each plug is seated to inhibit passage of liquid from the member end. Each plug comprises a body component seated by interference fit and has an integral axially extending component (86', 88') that forms a mounting pin by which the rotor can be mounted within bearing parts (24, 28) of the housing. Any closure plug may be assembled from separate plug body and mounting pin component that is fixed or rotatable with respect to the body. The closure plugs may extend along the tubular member and be coupled to each other or be formed integrally as a unitary body. Alternatively, assembled plugs may share a common mounting pin component that extends between discrete plug bodies.

Title: Digital cordless telephone set
Inventor: HOKAO TOMOAKI
IPC: H04M1/00
Filed: 1998-02-10
Granted: 2001-09-19
Abstract: In a digital cordless telephone set as a subsidiary unit, when both a radio wave from a radio base station connected to a public line and a radio wave from a master unit connected to a private line can be received, a sensor detects whether the subsidiary unit is placed on a charger. If the subsidiary unit is placed on the charger, the simultaneous wait mode is set while assigning the private line to a priority system and the public line to a nonpriority system. If the subsidiary unit is not placed on the charger, the simultaneous wait mode is set while assigning the public line to the priority system and the private line to the nonpriority system. In any case, the incoming call wait period of the nonpriority system is set to be longer than the normal period. With this arrangement, the frequency of turning on the main power supply of the subsidiary unit can be decreased to minimize power consumption in the incoming call wait mode.
