Patent NO-177908-C (NO)
Inventor: DURBUT PATRICK
IPC: C11D3/43
Filed: 1990-09-20
Abstract: A liquid detergent composition which is in liquid crystal form comprises a synthetic organic surface active agent, as the detergent component, which preferably includes one or more nonionic detergents of the ethoxylated higher fatty alcohol type, and a lesser proportion of anionic or cationic surfactant, such as sodium dialkyl sulfosuccinate or dicoco dimethyl ammonium chloride, a cosurfactant, such as tripropylene glycol butyl ether, a solvent for the soil, such as an isoparaffin of 9 to 11 carbon atoms or methyl cocoate (ester of methyl alcohol and coco acids) and water, with the water usually being the major component. Such compositions are useful for cold or room temperature cleaning of lipophilic soils, such as animal fats, from hard surfaces and from fabrics, and may be used as pre-treatments to loosen such soils from substrates to facilitate easier cleaning of dishes and laundry with conventional or the invented detergent compositions. The invention also relates to concentrated versions of the compositions, which are not in liquid crystal state but which upon dilution with water are converted to such state. Also within the invention are processes for pre-treating and cleaning materials soiled with lipophilic soils, using the invented liquid crystal detergent compositions. Additional processes of the invention are those in which liquid crystal detergent compositions are made by diluting concentrated compositions with water, and those in which lipophilic materials convert liquid crystal detergent compositions to microemulsion form, which latter processes occur during pre-spotting and cleaning applications when the liquid crystal detergent composition contacts the oily soil on surfaces being treated.

Title: Re-vegetation of tailings areas using recovered phosphates
Inventor: SHERIDAN JOHN PATRICK
IPC: C05B21/00
Filed: 1990-02-26
Granted: 2000-09-12
Abstract: This invention relates to re-vegetation o fmine teailings deposit areas. Generally mine tailings are highly acidic, having a pH of 2.0 or lower on a continuing basis. Fly ash from sanitary incinerators may have high amounts of phosphates of calcium, magnesium, or aluminum. If the fly ash is spread on the mine tailings deposit area, and water is introduced, complex chemical reactions arise which may result in the production of metal sulphides and phosphoric acid or super-phosphates of the metals. In any event, if metal sulphides are produced they are generally stable, and the phosphoric acid or metal superphosphates will release phosphates in a useable manner to any vegetation being grown in the area where the fly ash has been spread on the acidic mine tailings deposit area.

Title: Technique for object orientation detection using a feed-forward neural network
Inventor: MORRIS ROBERT J T
IPC: G06T7/00
Filed: 1990-03-29
Granted: 1993-10-12
Abstract: A TECHNIQUE FOR OBJECT ORIENTATION DETECTION      USING A FEED-FORWARD NEURAL NETWORK          Abstract The present invention relates to a technique in the form of an exemplary computer vision system for detecting the orientation of text or features on an object of manufacture. In the present system, an image of the features or text is used to extract lines using horizontal bitmap sums, and then individual symbols using vertical bitmap sums, using thresholds with each of the sums. The separated symbols are then appropriately trimmed and scaled to provide individual normalized symbols. A Decision Module comprising a Feed-Forward Neural network and a sequential decision arrangement determines the "up", "down" or "indeterminate" orientation of the text after a variable number of symbols have been processed. The system can then compare the determined orientation with a database to further determine if the object is in the "right-side up" "upside-down" or "indeterminate" orientation.

Title: Beam current limiter with brightness control threshold extension
Inventor: NEAL CHARLES BAILEY
IPC: H04N5/59
Filed: 1990-04-05
Granted: 2000-03-28
Abstract: A brightness limiter is responsive to a beam current control signal in a predetermined range of beam current operating values with an extended operating threshold for reducing brightness and reducing beam current. Operation of the brightness limiter responsive to certain noise in the beam current control signal during retrace is inhibited, the brightness limiter being otherwise responsive to the beam current control signal at operating values below the threshold. Operation of the brightness limiter may be inhibited by passing the beam current control signal through an AC filter. Alternatively, operation of the brightness limiter may be inhibited during retrace by interrupting propagation of the beam current control signet, or by preventing operation of the brightness limiter, for example, responsive to flyback pulses or pulses in timed relationship to flyback pulses.

Title: Chlorine-free wood pulps and process of making
Inventor: CRONLUND MALCOLM
IPC: D21C9/153
Filed: 1991-10-08
Granted: 1997-09-30
Abstract: This  invention provides for a batch and continuous process with countercurrent recycle of bleaching filtrates  for the    delignification and   bleaching   of   pulp.   Oxygen delignification of pulp is achieved in excess of from about 50% to  about  76%  as  measured  by  kappa numbers, while the pulp viscosity is minimally decreased in the range of from  about  2 to  about 5 cps. Bleaching of delignified pulp is achieved with peroxy compounds and ozone and pulp brightness of from about 82 to  88  ISO can be achieved with pulp containing zero level TOX from chlorine based bleaching chemicals and zero level  of  AOX in  the bleach effluents. Higher brightness of from about 90 to about 92 ISO can also be  achieved  by  addition  of  very  low levels  of  chlorine  based  bleaching chemicals. Corresponding bleach effluents contain  less  than  200  ppm  AOX.  Bleaching filtrates  can be recycled for pulp washing and for use with an organosolv pulping process which results in significant  energy savings and   mitigation  if  not  elimination  of  pollution typically  associated  with  chlorine  based  bleaching.   This invention  also relates to bleach pulp product derived from the process  and to an apparatus for carrying out the process.

Title: Uplink null intrusion rejection for satellite communications systems
Inventor: PROFERA CHARLES EDWARD JR
IPC: H04B15/00
Filed: 1993-02-11
Granted: 2001-11-20
Abstract: A satellite communications system includes a feed array and reflector receiving antenna coupled to a dual-mode network, for generating two channels, with independent signals representing two beams, one for each channel. Each output channel of the dual-mode network contains redundant information relating to a plurality of information channels. In the absence of an interfering signal or intrusion, the combined signals are amplified and block frequency-converted, then de-multiplexed into separate channels, which are each applied through selection switches to a transmitter multiplexes for retransmission. An alternate signal is tapped from each of the two received signal channels, phase controlled, and combined, to produce a combined signal representing a receive antenna beam with a null controllable in position in response to phase. The combined signal is demultiplexed into separate information channels. In the presence of an intrusion in one of the channels, the selection switch for that channel is set to an alternate position, in which the alternate signal is selected for transmission. Since the alternate signal includes a null in the receive beam, the position of the null may be set to the location of the intrusion signal to suppress the signal.
