Title: Water soluble polymers for detergent compositions
IPC: C09K8/03
Filed: 1989-01-09
Abstract: Detergent compositions include water soluble 
polymers which serve as builders, lime soap 
dispersants, and antiredeposition agents. The water 
soluble polymers, which fall into two structural 
classes, are especially useful in commercial heavy 
duty liquid detergent compositions, with which they are 
compatible in effective amounts. The water soluble 
polymers enhance several detergent properties such as 
antiredeposition and lime soap dispersancy with a 
concomittant loss in other detergent composition 
characteristics. Further, the polymers are compatible 
with enzyme containing liquid detergents. In the first 
structural class surfactant radicals are distributed 
along the polymer chain, which also includes pendent 
carboxyl and/or carboxylate salt radicals. An example 
of a polymer within this class is represented by the 
formula: 
  
wherein: EO = ethylene oxide  
C₁₆-C₁₈ = a(C₁₆-C₁₈)alkyl group or an aralkyl 
or alkaryl group in which the alkyl portion 
contains 16 to 18 carbon atoms.  
In the second structural class the polymers are 
terminated by a surfactant radical. The water soluble 
polymers are also effective dispersants for a number of 
particulate materials including kaolin clay and 
powdered coal, and inhibit the precipitation of calcium 
chloride and barium sulfate.

IPC: C30B23/02
Filed: 1989-06-09
Abstract: Method of depositing an oxide superconductor on 
a substrate by epitaxially growing a 0.05-2.0 micron 
thick, single crystal buffer layer of magnesia or cubic 
zirconia on a single crystal sapphire substrate; and then 
growing an oriented oxide superconductor layer on the 
buffer layer. The sapphire substrate with a thin buffer 
layer provides for low dielectric losses (negligibly 
larger than sapphire by itself), the oxide superconductor 
can be oriented in a desired direction to provide higher 
current carrying capacity, and reaction between the 
sapphire substrate and the oxide superconductor (especial­
ly that due to diffusion of aluminum) is minimized. 
Preferably, the buffer layer is 0.1-1.0 micron thick, 
magnesia in a (111), or (100), or (110) orientation.

Title: Optical fibre monitoring
IPC: G01L1/24
Filed: 1989-09-29
Abstract: A clip-on device for detecting whether or not an optical fibre F is carrying a light signal subjects a first portion of an optical fibre to microbending and detects any light escaping from the fibre as a result. The device comprises an anvil 2 having an undulating surface and a pulsed pressure pad 1, driven by a motor 10, for urging an optical fibre F against the undulating surface of the anvil so that a portion of the fibre is subjected to microbending of a gradually increasing extent. A second portion of the fibre is subjected to macrobending by a light guide 8 or 9, which macrobending is insufficient, by itself, to cause a substantial amount of light to escape from the fibre, but serves to concentrate the light caused to leak from the fibre by microbending of the first portion of the fibre. A control unit 13, operatively coupled to the photodetectors 6 and 7 associated with the light guides 8 and 9 and to the pressure pad 1 gives an output indication on receipt of a signal from the photodetector 6 or 7 that escaping light has been detected and, on receipt of such signal, stops the motor 10 so that the pressure pad 1 is stopped from further increasing the extent of microbending of the portion of the fibre. <IMAGE>

Title: Method of forming an oxide liner and active area mask for selective epitaxial growth in an isolation trench
Inventor: ROBINSON FREDERICK J
IPC: H01L21/763
Filed: 1990-04-23
Abstract: A new method is used to fabricate an isolation trench to 
prevent spurious epitaxial growth at the top edge of the trench 
opening and at pin holes in oxide over the active area. The 
method involves etching a deep trench into a semiconductor wafer 
that is patterned with a mask oxide layer, and then depositing a 
low temperature oxide, followed by growing a thermal oxide layer 
under the mask oxide and in the trench. When the oxide at the 
bottom of the trench is removed to provide a seed for the growth 
of selective epitaxial silicon, an oxide layer thick enough to leave a 
protective coating over the active area and at the trench opening 
is provided which prevents spurious epitaxial silicon growth.
Patent EP-0398634-A3 (EP)
Title: Bias current control for potentiometric measurements
IPC: G01N27/416
Filed: 1990-05-15
Abstract: Apparatus and method are provided to ensure accuracy of a measurement signal obtained using a potentiometric sensor (10) placed in a solution (12). The apparatus includes an interface amplifier (26) that generates a relatively large turn-on bias current whenever the amplifier is initially powered on. To avoid polarization of the potentiometric sensor (10) by the turn-on bias current, a switch device (40) is used to direct the turn-on bias current along a path away from the potentiometric sensor (10). The switch device (40) is controlled using a timer circuit (42) that causes a change in position of the switch device (40) after a predetermined time delay. During the time delay, the bias current reduces to a normal value and polarization of the potentiometric sensor (10) has been avoided. An accurate measurement of a physical parameter associated with the solution can then be taken without the detrimental effect of the turn-on bias current on the potentiometric sensor. The apparatus has particular utility in obtaining water quality data, such as hydrogen potential, specific ion potential and oxygen reduction potential.

part in the polymerization vessel but also near the 
interface between the gas phase part and the liquid phase 
part, so that the thus obtained polymer can provide a molded 
item having few fish eyes and low in initial coloration,

Title: Solid state image pickup apparatus with automatic correction of defective pixels
IPC: H04N5/335
Filed: 1993-03-15
Abstract: A solid-state image pickup apparatus for use as a video camera has a 
defect detecting mode and an operation mode. The solid-state image 
pickup apparatus includes a solid-state image sensor (2) having pixels 
(I cr ) arranged in rows and columns for producing an output signal 
representing a detected image. The solid-state image sensor operates 
in a field reading mde for reading electric charges from the pixels in 
approximately one field period such that the electric charges of the 
pixels (I₄₁, I₃₁; I₄₂, I₃₂) of two adjacent columns are summed before 
being outputted from the solid-state image sensor, the summed electric 
charges being different in even and odd-numbered fields, and also 
operates in a frame reading mode for reading electric charges from the 
pixels in approximately one frame period such that the electric charges 
of the pixels (I₄₁, I₄₂; I₂₁, I₂₂) of one of two adjacent columns are read 
in even-numbered fields and the electric charges of the pixels (I₃₁, I₃₂; 
I₁₁, I₁₂) of the other of two adjacent columns are read in odd-numbered 
fields. The positions of defective pixels of the solid-state image 
sensor are detected in the defect detecting mode, the defective pixels 
causing noise in the output signal at corresponding times in sampled 
data of the output signal. The detected positions of the defective 
pixels are stored in a memory (13). When the defect detecting mode is 
selected, the solid-state image sensor is controlled to operate in the 
frame reading mode.
