Title: Recombinant pseudomonas exotoxin: construction of an active immunotoxin with low side effects
IPC: A61K47/48
Filed: 1987-09-23
Abstract: The present invention relates to various modified forms of Pseudomonas exotoxin exhibiting low toxicity to human or animal cells by itself but retaining its enzymatic activity. The modified Pseudomonas exotoxin of the present invention has ADP ribosylating activity but lacks all or part of domain II (responsible for translocation across cell membrane) of the native toxin. A preferred modified Pseudomonas exotoxin of the present invention further comprises a modification in the receptor binding domain IA of the native Toxin. Conjugates (immunotoxins) comprising a modified Pseudomonas exotoxin and a targeting carrier, such as an antibody or a growth factor, methods for producing a modified Pseudomonas exotoxin or conjugates thereof and compositions suitable for administration to a mammal for achieving targeted cytotoxin activity are also disclosed.

Title: Non-human carbonyl hydrolase mutants, dna sequences and vectors encoding same and hosts transformed with said vectors
IPC: C12N9/54
Filed: 1987-04-28
Abstract: Novel carbonyl hydrolase mutants derived from the amino acid sequence of naturally-occurring or recombinant non-human carbonyl hydrolases and DNA sequences encoding the same. The mutant carbonyl hydrolases, in general, are obtained by in vitro modification of a precursor DNA sequence encoding the naturally-occurring or recombinant carbonyl hydrolase to encode the substitution, insertion or deletion of one or more amino acids in the amino acid sequence of a precursor carbonyl hydrolase. Such mutants have one or more properties which are different than the same property of the precursor hydrolase.
Patent EP-0246875-A3 (EP)
IPC: C08L63/00
Filed: 1987-05-20
Abstract: A modified liquid polymer is produced by reacting in the presence of a 
catalyst at least one mercaptan-terminated liquid polymer having functional 
linkages in the backbone with an amount below stoichiometry of at least one 
multi-functional cross-linking agent having mean or average functionality 
greater than 2. The amount of the cross-linking agent(s) is calculated by 
stoichiometry such that between 1 and 60 per cent of the mercaptan groups, 
preferably between 3 and 30 per cent, of the original liquid polymer or 
polymers are reacted. The multi-functional cross-linking agent may be a 
polyfunctional isocyanate-terminated polymer or a polymer having oxirane ring 
functionality such as a polyfunctional epoxide resin. Modified liquid 
polymers produced by the method retain cross-linkable mercaptan 
terminations and when cross-linked display improved mechanical properties 
and are useful for example in adhesives, sealants, coatings, extrusions and 
mouldings.

IPC: G01N27/12
Filed: 1987-06-17
Abstract: Hydrogen Sulphide is a toxic gas present in many environments. It is necessary for a detector to be highly sensitive and not to respond to other common gases. The sensor is made up of electrodes (5) coated with a thin layer (6) of material comprising the oxides of molybdenum and tungsten and in the presence of hydrogen sulphide gas, changes its resistance. The layer is formed in such a way that a bronze-like ordered lattice is formed, containing molybdenum, tungsten and oxygen ions.
Patent EP-0270205-A3 (EP)
IPC: A61M27/00
Filed: 1987-08-20
Abstract: A biomedical implantable shunt is provided having an 
enlarged generally circular pump body (12) and a perforated 
distal and proximal catheter (20, 22) attached to said body. The 
catheters are intended to have excess length so they can 
be cut to proper length as necessary to fit a specific 
patient. The pump body includes a vestibule (14) at the outlet 
end directly connected to the distal catheter (20). A pair of 
one-way miter valves (60, 62) are provided within the pump body. 
The inlet valve (60) is directly connected to the entrance 
provided for the proximal catheter (22) while the outlet valve 
is positioned within the vestibule which is connected to 
the distal catheter. A longitudinal ridge (88) is provided in 
the base member (46) of the pump body with one end of the 
ridge positioned directly under the inlet valve to 
eliminate the possibility of the valve becoming sealed in 
the closed position during the pumping operation. 
Additional longitudinal as well as transverse ridges (90, 94) can 
be provided in the base section as well as the interior 
of the pump dome (30) to provide strength and rigidity within 
the pump body. The pump body portion of the shunt is 
formed as a one-piece integral unit by means of injection 
molding. Two separate mold cores are provided which are 
cantilevered with the pump body core supported by the 
vestibule core. The vestibule core is in turn supported 
from the interior of the mold so as to hold both cores in 
proper position and alignment during the molding process. 
The inlet and outlet apertures for the proximal and 
distal catheters respectively, are sized according to the 
elasticity and tear-resistance of the materials used in 
the molding process so that the cores can be extracted 
from the article without tearing or otherwise injuring 
the pump body material.

Patent EP-0295409-A3 (EP)
IPC: G06F1/10
Filed: 1988-05-03
Abstract: Using a variable-duration clock, together with 
programmable duration definition means to alter the 
clock waveform (8) within strict rules, permits the 
programmer to arrange appropriately short durations 
for short data transfers, and to arrange appropriately 
longer durations for longer data transfers in an array 
processor of myriad processing elements. There is no 
need to allow sufficient time in every clock cycle for 
worst case data transfer between remote processing 
elements (3).  
     The clock waveform has three recognizable edges 
(A,B,C) regardless of loss of sharpness during its 
travel to the various processing elements. The 
convention that three skew-sensitive activities, READ, 
WRITE and OPERAND SUPPLY conform to respectively 
assigned edges as follows:  
A = READ;  
B = OPERAND SUPPLY;  
C = WRITE (Read next)  
     The processing elements synchronize with the clock 
waveform, which is optimized for the instructions of 
the program being executed. There is no time wasted 
allowing for worst case data transfers possible in 
certain instructions but not possible in other 
instructions.

Title: Improved teletext receiver
IPC: H04N7/088
Filed: 1988-05-04
Abstract: There is described an improved receiver for an information 
transmission system, represented by a plurality of pages, each one 
selectable by the user among all those which are receivable, some of 
said pages being of the so called revolving type, the receiver 
comprising a memory (3) for one or more of said pages, command means (1) 
providing for a plurality of keys, which may be pressed by the user 
in order to produce command signals, control means (2), coupled to said 
command means in order to produce suitable active signals as a 
consequence of said command signals, and a decoding circuit (4) coupled 
to said control means, capable of receiving, selecting, processing 
and displaying the information pages when said active signals are 
received, wherein one of said command signals is the so called "stop" 
(or Halt) signal, which is used to stop the automatic changing of 
said revolving pages; the main characteristics of the receiver is 
represented by the fact that said control means provide, when said 
"stop" signal coming from said command means is received, for 
verifying if the page which is actually received is a revolving page, 
and in the affirmative case, for sending out active signals to said 
decoder and said page memory, so that, beside freezing the displaying 
of the page which is actually received, the pages following the page 
which is actually received and pertaining to the same group of 
revolving pages are memorized in said memory.

and data can be programmed into the spare memory cells 
after the completion of the manufacturing process. The 
operation of programming data into the spare memory 
cells of the spare memory cell array (20) is effected by 
use of a write-in address buffer (22) and a write-in 
decoder (21). When a row or column including a defec­
tive memory cell is designated in the main memory cell 
array (11 and 12), the row or column of the spare memory 
cells in the spare memory cell group (20) is activated.
