Title: Apparatus for manufacturing chlorine dioxide
IPC: C01B11/02
Filed: 1986-12-16
Abstract: Chlorine dioxide is increasibly used to bleach pulp and the like. Chlorine dioxide is produced in a reactor, which contains a plurality of superimposed bubble cap trays, which are provided with passages for the gas and with duct, which is independent of the gas passages and serves as an overflow for the liquid. In order to maintain a maximum ClO3/acid ratio for the longest time possible, the reaction chamber above each bubble cap tray is divided into a large number of reaction compartments by vertical partitions, which define openings for the passage of the reaction liquid. Acid can be supplied to each compartment. The partitions can be used to define in each reaction chamber any desired number of reaction compartments, which are connected in parallel for the flow of acid and are connected in series for the flow of the chlorate solution.

Title: Process for recovering refractile bodies containing heterologous proteins from microbial hosts and the use thereof
IPC: C07K14/555
Filed: 1986-06-25
Abstract: A refractile material containing a heterologous protein is recovered from a host microorganism cell culture transformed to produce the protein. One recovery process involves disrupting the cell wall and membrane of the host cell, removing greater than 99% by weight of the salts from the disruptate, redisrupting the desalted disruptate, adding a material to the disruptate to create a density or viscosity gradient in the liquid within the disruptate, and separating the refractile material from the cellular debris by high-speed centrifugation (Figure 1 Another version of such a recovery process comprises the further steps of solubilizing the refractile material under reducing conditions, organically extracting the solubilized refractile material, and isolating said refractile material from the extractant (Figure 2).Preferably the protein is recombinant IL-2 or IFN-β and the salt removal step is carried out by diafiltration.
Patent EP-0200611-A3 (EP)
IPC: H04N5/08
Filed: 1986-04-08
Abstract: A color image processing system is described which 
provides more realistic hard copy color images from 
composite video system input signals than previously 
available. The image processing system includes a 
synchronization separator 20 which operates to separate 
the synchronization pulses from the analog video 
information supplied. The separator includes an amplifier 
with a pair of input terminals. The video is coupled to 
one of the input terminals and a feedback loop coupled 
between an output terminal and the other input terminal. 
In this manner the negative synchronization pulses may be 
amplified while the positive video signals are limited. 
The extracted sync signal is used to control an 
analog-to-digital converter 70. The analog video 
information is then converted to digital form by an 
analog-to-digital converter. The converter operates under 
control of a time base generator 100, including a 
programmable delay line 300, which receives 
synchronization pulses from the synchronization separator, 
and following a programmable time delay supplies a control 
pulse to the converter to cause it to sample the analog 
waveform and convert it to digital format. The generator 
100 employs a delay line 300 to detect the fraction of a 
system clock period between the sync pulse and the next 
clock pulse. The specified number of clock pulses are 
allowed to elapse. Then the delay line 300 is used to 
provide the necessary further delay. Once the signal is 
digitized, it is converted from an additive color system 
to a subtractive one and enhanced before being supplied to 
the color plotter 8.

Title: Device for the execution of a transitional connection between two right-angled contiguous surfaces
IPC: E04F19/04
Filed: 1987-12-01
Abstract: A device is disclosed for forming a connecting transition between two perpendicularly adjoining surfaces, of which at least one surface is provided with a rigid covering, in particular ceramic tile. The device allows for compensation of the varying stresses occurring in the surfaces bounding the joint combined with adequate sealing of the area of transition. The device is intended to find application in particular as a connecting transition between the edge of a bathtub and the adjoining wall and consists of a single-piece plastic angular profile. A sealing strip with a softened sealing lip is molded onto a leg of the angular profile which is formed of hardened material so as to extend the leg. The sealing lip has an adhesive profile arranged on its outer side in the lengthwise direction of the angular profile. By virtue of its elasticity, the molded sealing lip of the single-piece profile is biased against the surface to be sealed. Because the sealing lip is kept connected to such surface by an adhesive connection, it always acts against such surface in a sealing manner.

IPC: C23C4/18
Filed: 1987-03-19
Abstract: Techniques are described for the formation of an 
abrasive surface layer (14) on an article (12). The 
surface layer (14) is characterized by a single layer 
of particles (18) which are evenly spaced apart, in a 
high density arrangement, within a metallic matrix 
(16). In the deposition of the particles (18) on the 
article (12), a vacuum is drawn through a perforated 
plate (42), wherein the location of each perforation 
(44) corresponds to the desired location of one 
particle (18) on the article surface (11). The 
vacuum holds one particle (18) over each perforation 
(44) in the plate (42), then the plate (42) is 
positioned over the article (12) and the vacuum level 
adjusted so that the particles (18) fall onto the 
article (12). The matrix (16) is then deposited by 
plasma arc spraying a superalloy powder. The 
invention is particularly suited to the formation of 
an abrasive layer on the tip surface of a blade used 
in a gas turbine engine.

Abstract: A method for preparing a fecal sample for immunoassay testing 
comprising the steps of dispersing a sample of from 1 to less than 
10 wt.% of a stool sample in an aqueous fecal test solution 
formulated with one or more preservatives, analyte stabilizing 
agents and endogenous interference reducing agents. The fecal 
solids are then permitted to settle to form a liquid phase 
substantially free from fecal solids, and the clarified liquid 
phase is removed to provide a test sample free from fecal solids. 
The fecal test solutions contain suitable stool stabilizers such as 
buffers and antimicrobial agents, analyte protecting agents such as 
proteolytic, reductive or oxidative enzyme inhibitors, endogenous 
assay interfering enzyme inhibitors such as a reducing agent, and 
non-specific binding inhibitors such as animal proteins. The stool 
sample should be fresh or be fresh frozen and thawed immediately 
before dispersion in the buffer solution. The sample is suitable 
for any solid-phase immunoassay determination of a fecal sample 
analyte.  
     A method for determining analyte in a stool sample comprises 
conjugating anti-analyte antibody adhered to a insoluble support 
with analyte in the clarified sample, and determining the presence 
and extent of such conjugation. For determining human hemoglobin 
in a sample of human stool, the aqueous fecal test solution 
preferably contains a proteinase inhibitor, formaldehyde and an 
animal albumin.
