Patent EP-0263288-A3 (EP)
Title: Extended floating point operations supporting emulation of source instruction execution
IPC: G06F9/44
Filed: 1987-08-25
Abstract: In a system which emulates execution of source CPU 
instructions (21) and includes a translating unit (translator) (20) 
for converting source instructions (21) to target instructions (23) 
and a target CPU instruction unit (10) for processing and 
issuing translated target instructions, provision is 
made for accelerating instruction, translation, issue, 
and execution when certain source floating point 
arithmetic instructions are emulated for execution. 
When a source floating point arithmetic instruction is 
emulated, a token is placed in a wait queue in the 
translator (20) to prevent the translation of any source 
instructions and issue of any target instructions 
until condition and interrupt information is available 
and validated. In addition, emulation of source 
RX-type floating point instructions is enhanced by 
provision of registers in the instruction unit which 
receive X-field denoted operands, and which thereby 
permit a target CPU execution unit to perform the 
emulation by conducting register-to-register operations.

Patent EP-0251681-A3 (EP)
IPC: G03H1/00
Filed: 1987-06-24
Abstract: A method of manufacturing integrated circuits using 
holographic techniques by interference between an input 
beam (S) and a reference beam (R) generated from laser 
sources (24,25). A holographic image of the object 
formed on a mask window (19), is formed on recording 
emulsion coated on a glass slab (16) by means of 
interference between the input beam (S) which has passed 
through the mask (18) and the reference beam (R) which is 
reflected from the surface (X) of a prism (22) in contact 
with the glass slab (16). In order to reproduce the 
holographic image on a silicon slice which replaces the 
mask (18), the reference beam is replayed in the reverse 
direction through the prism (22) such that the 
interference between the input beam (S) and the replayed 
reference beam (R) causes the holographic image to be 
created as a real image in the silicon slice.

Title: Air cooling ring for plastic film
IPC: B29C48/90
Filed: 1988-01-07
Abstract: A dual flow air ring (10) is used to cool the exterior surface of thermoplastic tube (40) after the plastic is extruded from an annular die (20). The surface of the wall forming the divider between the upstream and downstream flow paths which confronts the extruded tube (40) is shaped to include a region of decreasing diameter in the direction of tube travel so that the flow path for air issuing from the lower discharge (37) formed between the extruded tube (40) and the surface is caused to converge. This converging flow stabilizes the tube (40) thereby permitting more vigorous cooling and consequently higher production rates.

Abstract: Sulfated polysaccharides, such as fucoidan, dextran 
sulfate, heparin and 
-, κ- and λ-carrageenans proved to 
be potent and selective inhibitors of human 
immunodeficiency virus type 1 (HIV-1)  in vitro . No 
toxicity for the host cells was noted with these compounds, 
so that the selectivity indexes, as based on the ratio of 
the 50% cytotoxic dose to the 50% antiviral effective dose, 
were equal to or in excess of 100.  
     Dextran sulfates of low molecular weight (5000, 
8000) exhibited a significant inhibitory effect on HIV-1 at 
a concentration that was not markedly inhibitory to the 
blood coagulation process.

Patent EP-0279685-A3 (EP)
IPC: H01J37/32
Filed: 1988-02-19
Abstract: A glow discharge unit suitable for making 
surfaces such as carbon-coated electron microscopy 
grids and glass cover slips hydrophilic. The use of 
a vacuum leak detector (Tesla coil) in place of a 
conventional high voltage power supply and a small 
plastic desiccator for the vacuum chamber make the 
unit very inexpensive. Due to the small volume of 
the chamber and the simplicity of the unit, the 
whole glow discharge process can be carried out in 
only 2 to 3 min., a time considerably shorter than 
that required for conventional vacuum evaporators. 
The hydrophilic surfaces thus obtained improve 
adsorption of particles by several orders of 
magnitude in preparation for negative staining, 
freeze-drying and other procedures.

Patent EP-0335105-A3 (EP)
Title: Method to prevent surge of a centrifugal compressor by vent control
IPC: F04D27/02
Filed: 1989-02-22
Abstract: In the case of known control methods the intake volume flow to the compressor and the compressor final pressure measured after the compressor are included in the venting control. Disturbances in the through-flow which have their cause in a process downstream from the compressor are thereby only detected once they have spread through the compressor to the intake side. Under unfavourable conditions intervention by the venting control may therefore already be too late to prevent surging of the compressor. The new method is intended to rectify this drawback. 
<??>The new method proposes that in addition the delivery flow to the process downstream from the compressor be detected and taken account of in the venting control. This results in prompt reaction of the venting control to changes in the through-flow which are caused by the downstream process. 
<??>The new method is particularly suitable for the control of turbocompressors on which the downstream process is a possible cause of disturbances with changes in the through-flow.

Abstract: A method and apparatus for minimizing memory 
read latency in a digital computer system which includes a 
system control unit (SCU) with an associated main memory, 
and a plurality of independent central processing units 
(CPU's), each CPU having an associated writeback cache. 
Data requests from a requesting CPU start a normal read

concurrently begin a search for the location of any 
modified version of the requested data in the SCU data 
storage location directory, which stores the location of 
modified data located in both the SCU main memory and the 
caches of all the CPU's. The SCU main memory read cycle 
is aborted if a modified version of the requested data is 
found in any of the CPU caches, and the modified version
