Title: Stabilized vacuum apparatus for industrial multiple-bed hide driers
Inventor: CORNER ANTONIO
IPC: F26B5/04
Filed: 1994-03-21
Granted: 2005-05-31
Abstract: The apparatus includes a main vacuum source (PA) that can be connected to a series of evaporation beds (1, 1', 1") to product a negative pressure having a preset value in the beds, in steady-state operating conditions. There is a secondary vacuum source (P B) which is suitable to produce, in one bed at a time, a negative pressure which is close to the steady-state value, and there is a valve means to selectively connect each bed, which is initially at ambient pressure, first to the secondary vacuum source (P B) and then to the main vacuum source (P A), so as to eliminate substantial pressure variations in the remaining beds when each bed is connected to the main vacuum source. The valve means includes, for each bed, a first electric valve (4, 4', 4") on a line for connection to the outside environment, a second electric valve (5, 5', 5") on a line (3, 3', 3") for connection to the secondary vacuum source (P B), and a third electric valve (6, 6', 6") on a line (2, 2', 2") for connection to the main vacuum source (P A). There is also a control unit (7) suitable to control the cyclic sequential opening and closure of the first, second and third electric valves of each bed.

Granted: 2005-10-04
Abstract: A method of converting industrial, domestic or other sludge (12), into a pelletized or granular fertilizer, as well as a sludge converter (10) for practicing the method. The sludge is dewatered to form sludge cake solids which are dried in a dryer (70), and then sorted with a sorter (80) into a sorted product comprising oversized, undersized and standard sized product. A  portion of the sorted product is recycled for mixing and sizing in a mixer (60) with the dewatered sludge cake solids. To control dust and odors, cyclones (130) and a condenser (140) remove a substantial portion of the gaseous particulate matter and condensable gases from the converter and any remaining heat energy to the dryer. The heat source exhaust gas by-products are filtered in a bag house (190) using a conditioner additive, such as lime or sodium bicarbonate (192), which may be reclaimed and supplied to the standard sized product to serve as a pelletizing binder, to enhance the fertilizer nutrient vale, or to enhance the fertilizer shelf life.

Abstract: An isolated and purified lactoferrin receptor protein is isolated and purified from bacterial pathogens, including Moraxella and Neisseria, and has a molecular weight of between about 70,000 and about 90,000, as determined by SDS-PAGE. Such lactoferrin receptor protein may be provided in combination with a lactoferrin receptor protein from the bacterial pathogen of a molecular weight of about 100,000 to about 105,000 daltons. The lactoferrin receptor protein may be produced by providing a solubilized membrane preparation from the bacterial pathogen containing lactoferrin receptor proteins, non-lactoferrin receptor proteins and other contaminants, complexing the lactoferrin receptor proteins with lactoferrin and purifying the resulting complexes substantially free from the non-lactoferrin receptor proteins and the other contaminants, and separating the novel lactoferrin receptor protein from the complexes. The lactoferrin receptor protein is useful in diagnostic applications and immunogenic compositions, particularly for in vivo administration to a host to confer protection against disease caused by a bacterial pathogen that produces the lactoferrin receptor protein or produces a protein capable of inducing antibodies in a host specifically reactive with the lactoferrin receptor protein.

Abstract: An increasing problem with the pulping chemical recovery system,  is the presence of chloride and potassium in the recovery boiler. Chloride and potassium increase inter alia the stickiness of carryover deposits and dust particles to the recovery boiler tubes, which accelerate fouling, corrosion and plugging of the recovery boiler. As the environmental legisla-tion becomes more stringent,  the degree of system closure increases. The present invention relates to a process by which the collected precipitator dust is leached, at a temperature exceeding 50°C,  for a residence time sufficient to get a chloride and potassium enriched leach solution and to remove at least a part of the content of metal ions in a solid phase. Said leach solution is electrochemically treated, preferably in an electrodialysis cell, in order to remove at least a part of the chloride and potassium therein. By the present process, the problem of sticky deposits in the recovery boiler can be substantially reduced. This means an improved energy effi-ciency as well as a higher degree of recovery of the pulping and bleaching chemicals.

Title: Cam-operated timer test procedure
Inventor: WEAVER ROBERT FRANCIS
IPC: H01H43/10
Filed: 1997-05-28
Granted: 2000-10-10
Abstract: An appliance timer has features to facilitate automated assembly or manual assembly. A timer housing base accepts timer components from two directions, and installation of components in either direction is along a straight axis. A motor in the timer engages a gear train which turns a drive cam. The drive cam impartsmotion to a camstack which then engages timer blade switches, and the blade switches operate the appliance. A subinterval is also supplied on the timer to allow periodic operation of a switch without the use of the camstack. The timer also features a quiet manual advance which removes the blade switches from communication with the camstack to allow an operator to select various timer programs without any of the clicking noises that are usually associated with timer program selection. Furthermore, a detent slider is positioned in communication with the camstack to provide a tactile feel for the operator of the timer when selecting between various timer programs.

Title: A distributed buffering system for atm switches
Inventor: WILLS JEFFREY MERLIN
IPC: H04L12/56
Filed: 1997-12-11
Granted: 2003-02-25
Abstract: The present invention provides for an ATM switch for transferring ATM cells from input channels to output channels.  The switch has a plurality of input and output ports, each connected to input and output channels respectively. The ATM switch also has a switch block connected between each one of the input ports and each one of the output ports to convey the cells from the input ports to the output ports, and a backpressure signal circuit.  Each input port has an input buffer which holds cells which arrive faster from an input channel than the input port can transmit to the switch block, and each output port has an output buffer holding cells when the cells arrive faster from the switch block than the output port can transmit.  The backpressure signal circuit sends a signal from a congested output buffer to those input port buffers which have transmitted a cell to the output buffer (during congestion) so that the input port buffers cease transmission.  The cells destined for the output buffer are then stored in the input port buffers.

Abstract: A one-part, low viscosity, moisture curable composition which exhibits excellent shelf stability in the absence of water, but which quickly cures at ambient conditions upon exposure to moisture in the air is a substantially anhydrous mixture containing an acetoacetate functional compound and a polyisocyanate functional compound. The composition can be suitably formulated for use as an ambient temperature, moisture curable adhesive, sealant or coating composition. The acetoacetate functional compounds have a relatively low viscosity as compared with conventional isocyanate functional compounds and thereby reduce or eliminate the need for plasticizers, organic solvents, or both. The cure chemistry of the composition simultaneously consumes and generates moisture at approximately the same rate thereby facilitating rapid cure under even low humidity conditions, and allows for efficient and facile curing of even thick layers of the composition.

Title: Information network access apparatus and methods for communicating information packets via telephone lines
Inventor: RICHARDS ROGER ST PATRICK
IPC: H04L12/413
Filed: 1996-09-11
Granted: 2002-05-21
Abstract: Access to a CSMA/CD (Carrier Sense Multiple Access with Collision Detection) network (10) is provided via a telephone line (12) by providing a master modem (34) at the head end and a slave modem (32) at the subscriber end of the line.  The master modem provides a CSMA/CD interface (36) to the network and controls half duplex communications with the slave modem via the line to avoid collisions of information packets on the line. The information packets are enveloped in frames on the line with error checking information; control information between the modems is contained in the same and/or in separate frames. The modulation method and signal bandwidth can be varied depending on errors to provide optimum communications capacity via any particular line, and a ratio of upstream to downstream information packets can be varied depending on buffer fills at the modems. The master modem can be multiplexed for multiple lines. The modulated signal frequencies are above telephone signal frequencies so that each line can be frequency diplexed for simultaneous telephone communications.
