Patent EP-0245019-A3 (EP)
IPC: A61K49/04
Filed: 1987-04-29
Abstract: A method for imaging the GI tract and the intestinal wall is 
described. The method comprises administering to a mammal a 
low density contrast medium comprising an oil in water emulsion 
containing from about 2 to about 50 percent by volume oil, and 
obtaining images of the GI tract and the intestinal wall. Also 
described is a low density contrast medium comprising an oil in 
water emulsion containing from about 2 to about 50 volume 
percent oil and a predetermined amount of soluble salts or sugars 
to maintain homeostasis in the intestine.

Title: Yeast promoter
IPC: C12N15/81
Filed: 1987-08-28
Abstract: A hybrid yeast promoter comprising constituents of the 5' non-coding PGK region and, as an upstream activation sequence, the upstream activation sequence of the GAL10 gene of Saccharomyces cerevisiae, and which does not contain the endogenous PGK upstream activation sequence. Preferably the GAL10 upstream activation sequence is provided at a site from which the PGK upstream activation sequence has been deleted. The hybrid promoter confers galactose regulation of gene transcription.
Patent EP-0266057-A3 (EP)
IPC: C12N5/00
Filed: 1987-09-25
Abstract: A synthetic gene encoding an exogenous 
protein has been assembled and inserted into a 
eucaryotic secretion expression vector containing the 
cytomegalovirus immediate early (CMV-IE) transcrip­
tional regulatory region, any one of a variety of 
mammalian secretory signal peptides and a portion of 
the bovine growth hormone gene encoding transcription 
termination sequences. The recombinant plasmid 
encodes the amino acid for the fusion protein that 
contains the mammalian secretory signal peptide and 
the amino acids of the protein to be secreted. This 
plasmid, when transiently introduced into cultured 
mammalian fibroblasts, directs the synthesis of the 
fusion protein, the subsequent proteolytic removal of 
the secretory signal peptide and the secretion of the 
protein into the culture media. The recombinant 
proteins produced by these cells are biologically 
active.
Patent EP-0263653-A3 (EP)
Title: Copier fuser control
IPC: G05D23/24
Filed: 1987-10-02
Abstract: A fuser temperature control using a resistive bridge driven power circuit. At the 
beginning of each positive half cycle of the AC line voltage, the possible firing of a triac (104) 
is delayed by 1090 microseconds. During this delay, the fuser temperature is checked by 
measuring the foil heaters resistance with a DC bridge circuit (102). One leg of this bridge 
circuit contains the foil heater (100). The other leg of the bridge has a potentiometer (110) to 
set the temperature of the fuser. The output of the bridge circuit is fed into a differential 
comparator (102) and D-type flip-flop (112). This combination gives high gain with very little 
sensitivity to noise. The differential comparator checks the fuser temperature (foil resistance) 
relative to the set point temperature (set point potentiometer). It determines whether the 
fuser temperature is above or below the set point temperature. The D-type flip-flop latches 
this information to either enable or disable the triac triggering circuitry for each full cycle of 
the line voltage. When the fuser temperature is below the set point temperature, power is 
enabled to heat the fuser. When the fuser temperature is above the set point temperature it 
is disabled to cool the fuser. This power decision is made at a rate of 60 Hz in order to keep up 
with the fusers instant-on characteristics.

Title: Net anchoring means
IPC: E04B1/76
Filed: 1987-11-26
Abstract: The present invention relates to a net anchoring means for anchoring of a reinforcing net outside an insulation layer which is secured for instance to a wall by means of a mounting means, for instance a collar sleeve (1; 3). The net anchoring means is introduced through a bore of the collar (3) of the mounting means (1; 3) and is prevented from being retracted in that hooks or nobbies (8) of the anchoring menas (6) engage the bore edge at the inner side of the collar (3). The anchoring means (6) also is formed with a through bore so that plaster can enter said bore thereby preventing the hooks or nobbies (8) from becoming released from the said bore edges.

Patent EP-0297989-A3 (EP)
IPC: G06F7/508
Filed: 1988-06-30
Abstract: In a multiplier unit implemented with carry/save 
adder stages and executing a modified Booth 
algorithm, the signals, required to complete the 2's 
complement in order to perform a subtraction 
operation during the multiplication procedure using 
carry/save adder cells, are entered in the first 
carry/save stage in the appropriate carry/save cell 
positions. In this manner, one less signal is 
processed by the time-critical least significant cell 
associated with each carry/save adder stage, thereby 
reducing the overall time delay associated with the 
multiplier unit and accelerating the multiplication 
operation.

Title: Bit map search by competitive processors
IPC: G06F12/02
Filed: 1989-06-28
Abstract: A method and apparatus for performing a bit map search 
of the allocation state of memory pages in a computing 
system. A competitive search is accomplished by a pair 
of dedicated microprocessors, each of which implements 
a differently optimized search procedure, to find a bit 
indicating an un-allocated page in the memory. The 
first processor to find such a bit interrupts the other 
processor. The first processor then calculates the 
free page location and informs the computing system of 
the location. The other processor is responsible for 
updating the bit map and summary buffers.

Title: Liquid crystal display device
IPC: G02F1/1368
Filed: 1989-11-28
Abstract: In an active matrix type liquid crystal display device 
which drives liquid crystal by applying voltage via a thin 
film transistor to each of transparent display electrodes 
(15) arranged in a matrix form, source buses (19) are each 
composed of a transparent conductive bus (19A) formed by a 
transparent conductive layer extending along each column of 
the display electrodes (15) and a metal bus (19B) formed by a 
high melting point metal layer overlapping and extending 
along the transparent conductive bus (19A). An insulating 
layer (23) is coated almost all over the surface of a base 
plate (11) on which the source buses (19) are disposed. The 
insulating layer has slot-like windows (19D) each extending 
along one side of each display electrode (15) so that the 
surface of the corresponding metal bus (19B) is partly 
exposed. A bus segment (19C) formed by a conductivity metal 
layer fills each slot-window (19D) to make direct contact 
with the metal bus (19B). With such a source bus structure 
in which the high conductivity metal layer and the 
transparent conductive layer are connected through the high 
melting point metal layer, the resistance value of the source 
bus (19) is small and remains stable for a long time.

Title: Wire-dot printer having printing wire driving device and manufacturing method thereof
IPC: B41J2/235
Filed: 1989-12-07
Abstract: A lever (130) for driving printing wires (198) has its 
outer end hooked to form a rotation support portion (196). 
A frame (100) for enclosing driving coils (130) and others 
has a yoke (150) having projections same in number as that 
of levers disposed on its end surface. The lever has the 
hooked supporting point locked by a recession formed bet­
ween the yoke projections and an end surface (114) of the 
frame and fixed by a retainer spring (210). When an exci­
ting current flows to the coils, the printing wires are 
struck on a platen round the supporting point. Since the 
lever is not provided with a rotating shaft member, the 
size in a cross direction is minimized. Accordingly, the 
number of levers enclosable in the frame is multiplied to 
enhance a packaging density.

Abstract: Alkyl phosphates, undiluted or dissolved in hydrophobic 
solvents are destroyed in situ by reaction with hydrogen 
peroxide in the presence of a 
catalyst system comprising a chromium 
compound, which dissolves in the aqueous phase, typically an 
alkali metal chromate, which is employed in conjunction with 
introduction of an alkali, preferably sodium hydroxide, or 
in the presence of an alkali buffer to keep the pH of the 
aqueous phase within a window spanning mildly acidic to 
mildly alkaline pH during the course of progressive 
introduction of the hydrogen peroxide, which often lasts 
from 3 to 10 hours, thereby enabling the oxidation of the 
alkyl phosphate to continue. The reaction is preferably 
carried out at a temperature of at least 60 o C, and 
particularly at about 65 to 75 o C, or at about the boiling 
point of the aqueous phase.
