Title: Sense amplifiers
IPC: G11C7/06
Filed: 1987-04-22
Abstract: A sense amplifier (11) includes two cross-coupled field effect transistors (M1, M2) coupled by capacitors (C1, C2) to respective bit lines (BL2, BL1) from a memory cell. During a precharging operation, the capacitors (C1, C2) are charged to precharged voltages indicative of the threshold dispersion voltage between the two transistors (M1, M2). Thereafter, during a sensing operation, the precharged voltages are applied to the gates (G1, G2) of the transistors (M1, M2) to compensate for the threshold dispersion voltage.

Title: Articles and methods for protecting substrates
IPC: H02G15/00
Filed: 1987-05-18
Abstract: This invention provides articles and methods for surface protection which comprises a layer of a gel material having a cone penetration of about 100 to about 350(10<-><1> mm) and an ultimate elongation of at least 100% and a covering layer of a flexible material which is flexible when installed on the surface to be protected and is hardenable or curable so that after installation the covering layer hardens to hold the gel layer in position and protect the gel layer from mechanical and other environmental conditions. This invention is particularly suitable for providing surface protection for underwater structures by applying the gel layer to displace the water from the surface which is underwater and providing a water curable covering layer which, after being applied to the surface, cures underwater to provide the required mechanical protection for the gel layer.

Patent EP-0272031-A3 (EP)
IPC: F24S90/00
Filed: 1987-12-07
Abstract: A waste or solar heat powered cooling apparatus 
utilises a heat collector (11) to convert waste or solar 
energy into heat stored in water. An evacuated chamber (13) 
houses a desiccant bed (14) and a sprayer (26) which 
introduces an adsorbate into contact with a heat exchanger 
conduit (31) extending within the chamber. Evaporation of 
the adsorbate in contact with the conduit cools a medium 
circulated within the conduit between the chamber (13) and a 
chilled water reservoir (32). The evaporated adsorbate is 
adsorbed by the desiccant bed (14) until a predetermined 
temperature or saturation level is reached, at which point, 
heated water from the collector (11) is passed through heat 
exchanger conduits in the desiccant bed (14) to regenerate 
the desiccant bed. Iterative adsorption and regeneration 
cycles maintain the chilled water in a desired temperature 
range.

Filed: 1988-01-28
Abstract: An analog-to-digital converter (10) comprises a 
set of comparators (12a-12f) for providing a set of 
different output signals whose logic states are a 
function of an analog input signal voltage and one or 
more reference voltage signals supplied by a resistive 
network (16). The comparators are connected to a 
decoder (20) for processing the thermometer code outputs 
of the comparators to generate a digital word output 
corresponding to the voltage amplitude of the analog 
signal. Several of the comparators are also connected 
to an error checking network (22), including a 
preconditioning circuit (100) and a detection circuit 
(102) for processing these comparator outputs to provide 
an error signal whenever one or more of the comparators 
are not operating properly. The error checking network 
and decoder are connected to an error correction circuit 
(26) for correcting the digital word signal in 
accordance with the error signal. Also, comparator 
circuits are provided which are well-adapted for high-­
speed operation and error checking.

minimum distance of the upper edge (11) of the sole (10) from its 
bearing face and to an acceptable maximum distance of the lower 
edge of the sole (10) from its bearing face. In this way, ski 
boots that can be used in conjunction with certain ski bindings 
can be sorted out in very simple fashion from those that are no 
longer suitable for this purpose.
Patent EP-0372578-A3 (EP)
IPC: G06F15/16
Filed: 1989-12-08
Abstract: A computer system in a fault-tolerant configuration 
employs three identical CPUs executing the same instruction 
stream, with two identical, self-checking memory modules storing 
duplicates of the same data. Memory references by the three CPUs 
are made by three separate busses connected to three separate 
ports of each of the two memory modules. The three CPUs are 
loosely synchronized, as by detecting events such as memory 
references and stalling any CPU ahead of others until all execute 
the function simultaneously; interrupts can be synchronized by 
ensuring that all three CPUs implement the interrupt at the same 
point in their instruction stream. Memory references via the 
separate CPU-to-memory busses are voted at the three separate 
ports of each of the memory modules. I/O functions are imple­
mented using two identical I/O busses, each of which is separate­
ly coupled to only one of the memory modules. A number of I/O 
processors are coupled to both I/O busses. Each CPU has its own 
fast cache and also local memory not accessible by the other 
CPUs. A hierarchical virtual memory management arrangement for 
this system employs demand paging to keep the most-used data in 
the local memory, page-swapping with the global memory. Page 
swapping with disk memory is through the global memory; the 
 
 
global memory is used as a disk buffer and also to hold pages 
likely to be needed for loading to local memory. The operating 
system kernel is kept in local memory. A private-write area is 
included in the shared memory space in the memory modules to 
allow functions such as software voting of state information 
unique to CPUs. All CPUs write state information to their 
private-write area, then all CPUs read all the private-write 
areas for functions such as detecting differences in interrupt 
cause or the like.

Title: High purity polyether polyols and process for preparing the same
IPC: A23L33/20
Filed: 1990-05-29
Abstract: The present invention concerns high purity 
polyether (PEG) polyol compositions and, preferably, 
polyethylene glycol (PEG) compositions which are useful 
to provide low calorie food for those who wish to 
control their tendency to be overweight. A process for 
the purification of polyethylene glycol through cation 
and anion ion exchange resins is known. However, this 
process does not remove the PEG oligomers. The present 
process comprises subjecting the polyether polyol 
compositions to membrane filtration to remove 
substantially all of the impurities, leaving only less 
than about 10 parts per million of the low molecular 
weight oligomers in the polyether polyol composition.
