Title: Image derived directional microphones
Inventor: ELKO GARY W
IPC: H04R1/40
Filed: 1990-05-08
Granted: 1995-04-18
Abstract: Second-order gradient directional microphones, both toroidal and unidirectional, derived using a first-order gradient sensor and an acoustically reflecting surface are disclosed. The sensor is positioned with its axis illustratively orthogonal to and suspended a few centimeters from a large acoustically reflecting surface. The resulting sensor image is phase reversed resulting in a transducer that is a linear quadrupole. The linear quadrupole can be described by two dimensions, the distance corresponding to the sensor's dipole distance and twice the distance from the reflecting plane. If the reflecting surface is large enough or if the wall of an enclosure is used, the resulting microphone becomes a second-order gradient unidirectional microphone. A perfect match between the sensor and its image from a good acoustic reflector results in an ideal second-order gradient microphone with 3 dB beam width of ?33° and no grating lobes below about 3 kHz for a spacing from the reflecting plane of about 2.5 cm. Toroidal directional microphones are formed using two or more sensors and an acoustically reflecting surface.

Title: Wash press modification for oxygen delignification process

IPC: D21C9/10
Filed: 1992-10-26
Granted: 1997-03-25
Abstract: Unbleached pulp is washed with an aqueous alkaline solution in a wash press to substantially uniformly distribute a first amount of alkaline material throughout the pulp.  The consistency of the pulp exiting the wash press is above about 18%, preferably between 25 to 35 percent by weight, and the high consistency alkali containing pulp is then treated with oxygen to effect /  The use of a wash press reduces the overall amounts of alkaline material utilized in the process compared to processes which add alkaline material to the pulp at low consistency.  Additional alkali may be applied, if desired, onto the high consistency pulp prior to oxygen delignification to provide a total amount of between 0.8 and 7 percent by weight of oven dry pulp. High strength, low lignin pulps are formed after oxygen delignification which may be further bleached to high brightness with reduced amounts of bleaching chemicals.

Title: Transportable reverse osmosis water purification unit
Inventor: HORNER KENNETH J
IPC: C02F1/44
Filed: 1993-10-07
Granted: 1998-07-07
Abstract: A self-contained, transportable reverse osmosis water purification unit has a limited throughput of no more than about 20 gpm of permeate in a single pass operation with reverse osmosis ("RO") modules which can be cleaned in place. When raw water is particularly fouled, the unit is operated in a double pass operation in which the permeate from the first pass is used as feed for a second RO module. The unit, referred to as a "purification container" "PC" or an ADROWPU because the PC is air-deliverable, comprises an enclosed weather-tight housing having a base on which the major components are removably mounted. For transportability, the PC has the overall dimensions of an ISO container, and is fitted with means to load and unload it on standard carriers. A high pressure pump is required to feed water freed from suspended solids to the RO modules.  The pump also delivers concentrate to a bladder tank where the concentrate is stored under pressure (about 100 psig) to flush a coarse filter automatically when it is plugged, which is often. Fine filters for solids removal are not plugged too often and can be replaced when the unit is not producing permeate. The ADROWPU is unique because of the economy of components used to produce a relatively large amount of permeate from any available raw water source. The placement of the components symmetrically about the center of mass of the PC is essential to allow the PC to be loaded and unloaded uneventfully, even if it is delivered by a helicopter.
