Patent EP-0326382-A3 (EP)
Title: Polymeric compositions
IPC: C02F1/52
Filed: 1989-01-26
Abstract: Water absorbent particulate polymers and their uses 
are described. Friable aggregates may be made by 
bonding substantially dry polymer particles with an 
aqueous liquid and drying the aggregates. These 
aggregates can be broken down to the individual polymer 
particles upon mixing with an aqueous medium and thus can 
have the flow properties of relatively coarse particles 
and the performance properties of relatively fine 
particles. They may be soluble and used as flocculants 
or viscosifiers or binders for, for instance, iron ore 
pelletisation. Alternatively they may be swellable and 
insoluble, for instance for converting a sticky 
particulate mass (such as coal fines filter cake) to a 
crumbly solid. When pellets are formed by compression 
moulding from a crumbly solid made by mixing water 
absorbent polymer particles with a sticky mass of 
inorganic particles (such as a coal fines filter cake) 
improved properties are obtained when the absorbent 
polymer particles are introduced in the form of a 
dispersion in water-immiscible liquid.

Title: Reading and decoding recorded data
IPC: G11B20/14
Filed: 1989-02-15
Abstract: In a method an apparatus for decoding data recorded on magnetic storage medium such as a "swipe card" to yield decoded data values, a magnetoresistive sensor is used to read the data as a pulse stream from the medium and to measure the widths of the received pulses. The data is preferably stored in the medium by the technique of two-frequency phase coherent recording (F2F). By comparing the widths of pulses to be decoded with the widths of previously read pulses to which data values have already been allocated circuitry for derivin a clock signal from a self-clocking recorded signal can be dispensed with. Pulse widths may be measured by monitoring the output of counters (20) incremented by a fast clock for the duration of each pulse, and the pulse widths are compared by comparing counter outputs stored in a memory (28) using a microprocessor (26). To allow data to be read from the recording medium at a wide range of pulse repetition rates without excessively increasing counter capacity, thecounters (20) may be clocked at a variable rate dependent on the repetition rate of the received pulses.

Title: Width determination of fractures intersecting a borehole
IPC: G01V3/20
Filed: 1989-09-29
Abstract: The present invention is directed to utilizing data indicative of formation resistivity 
and calculating the width and depth of a fracture therefrom. In the preferred embodiment, 
the present invention employs data acquired from a formation microscanner tool. 
Potential fracture locations are detected for acquired formation microscanner tool data 
preferably by taking into account the relatively slowly varying conductivity changes in the 
rock matrix, and separating them out from the high and narrow peaks generated by 
fractures. Each potential fracture location can be depicted as current from the formation 
microscanner tool versus azimuth, wherein the current measured by the formation 
microscanner tool is essentially flat for the formation but peaked for potential fracture 
locations. I have found that the area under the peak, herein referred to as "additional area 
under the curve, A", is related to the width of each potential fracture location according to 
the following equation, based on the specific tool parameters: 
  
The resistivity values for the formation and mud, R t  and R m , respectively, are typically 
known values. Thus, by calculating A, preferably by an areal integral, the width of each 
potential fracture location can be determined. The present invention optionally removes 
potential fracture locations indicative of spurious and scattered data, thereby obtaining 
sharper fracture images. Of the locations retained, the width of each fracture location is 
calculated according to the above equation and plotted as a function of azimuth and depth.

Patent EP-0587278-A3 (EP)
IPC: B01D63/10
Filed: 1993-07-09
Abstract: A sandwich of a permeate fabric material within 
a folded sheet of semipermeable membrane is spirally 
wound together with a sheet of porous feed pathway 
material about a mandrel which, upon its removal, 
provides a central hollow region in the wound element. A 
single band of adhesive seals the outer end of the 
envelope, and once wrapping is completed, a thin layer of 
porous tape holds the winding tight. A porous small 
diameter tube is inserted into a pocket adjacent the fold 
in the semipermeable membrane material near the center of 
the winding and serves as a permeate discharge conduit. 
Axial ends of the spirally wound subassembly are 
sequentially potted in resin to complete the basic 
fabrication of the element. Communication with the feed 
pathway material is provided by drilling through the 
resin into the center hollow region. The spirally wound 
element can be used as a replacement cartridge for a 
device having a permanent housing, or it can be 
integrally bonded within a surrounding pressure vessel 
assembly to form a disposable water purification unit. 
Feedwater supplied to the open center region flows 
spirally outward, while permeating purified water flows 
spirally inward to the porous tube which serves as a pure 
water discharge conduit.
