Title: Method of starting up a nuclear reactor, and a light-water and spectral-shift nuclear reactor for doing so
IPC: G21C7/26
Filed: 1985-05-30
Abstract: For operating a PWR with spectral shift during all combustion cycles and with undermoderation during some cycles only, the reactor structure is designed for receiving either one of two types of fuel assemblies, having the same geometry.

IPC: C22B30/00
Filed: 1987-01-22
Abstract: Mineral acids are freed from heavy metals, especially copper, arsenic, antimony and lead by precipitating the metals in sulfide form. To this end, the mineral acid is reacted with hydrogen sulfide or an alkali metal sulfide solution under pressure and with thorough agitation, and formed solid matter is subsequently separated from the mineral acid under the pressure selected. The mineral acid may conveniently by admixed initially with a filter aid and then treated with hydrogen sulfide or the alkali metal sulfide solution.

in one connector housing includes a receptacle comprised of 
a pair of split semi-cylindrical segments each pivotally moun­
ted to a drive shaft and adapted to threadably engage a threa­
ded member on a second connector housing. Rotation of the 
drive shaft causes the segments to interengage with the 
threaded member whereby to hold the housings together but 
rearward axial movement of a forwardly biased operating 
sleeve circumposed about the receptacle brings an annular 
groove thereon into register with outward annular ribs on the 
segments allowing the ribs to be received in the groove and 
the segments to pivot relative to their mounting whereby to 
release the threaded member.

Filed: 1987-06-10
Abstract: A combined digital-to-analog converter and latch 
memory circuit (10) includes an R-2R resistive ladder 
network (12) and a current-controlled latch memory 18. The 
R-2R resistive ladder network has plural input nodes (100 
and 102) and an analog signal output (104). Each of the 
input nodes corresponds to a different bit of a digital word 
that is to be converted to an analog signal. The current-­
controlled latch memory includes plural subcircuits (14 and 
16). Each of the latch subcircuits uses an amount of 
current to store the logic state of the bit of the digital 
word and to derive directly the node of the R-2R resistive 
ladder network. This configuration promotes the efficient 
use of space, power, and circuit elements.

Title: Slow-release composition for abating acid water formation, and method of making the same
IPC: A01N25/10
Filed: 1988-05-07
Abstract: Various chemolithotrophic bacteria such as Thiobacillus ferrooxidans by direct or indirect mechanisms catalyze the oxidation of metal sulfides and produce acid, i.e. suilfuric acid and soluble metal salts at a much faster rate than chemical oxidation. Elimination of such bacteria would inhibit the formation of the acid. The natural production of such acids is particularly troublesome in mines e.g. coal mines, since acid water is produced which is damaging to the environment. An effective method of abating or eliminating such acid water production is to apply a bactericide such as a biodegradable organic surfactant which at low pH values are bactericides and hence inhibit the bacteria from catalyzing the metal sulfides. The affected acid water site can thus be treated with the surfactant which provides a temporary or short term result usually for a few months. A long term solution, that is 1 year to several years, is provided through the use of a slow release composition of the present invention in which a heterogeneous matrix contains a thermoplastic domain and an organic surfactant domain. A suitable porosity is created when proper amounts of surfactant are utilized so that a long term slow release composition is formed. A method of making the heterogeneous matrix or slow release composition involves the dry blending of a thermoplastic compound and various processing aids, subsequently adding a bactericide thereto and mixing under shear and heat the resulting molten composition. A suitable slow release article can be formed such as pellets.

Title: Bit oriented communications network
IPC: H04L12/417
Filed: 1988-08-17
Abstract: A bit oriented communications network includes a plu­
rality of nodes (10, 11) interconnected by a broadcast 
communications medium (20). Each node (10, 11) samples 
inputs (17) connected to it and broadcasts the values of 
those inputs. A11 of the nodes then monitor the broad­
casts and map selected bits to outputs (18) connected 
locally through an output mapping process. Connections 
are established between inputs (17) and outputs (18) by 
the output mapping process, which in a first described 
embodiment functions by maintaining a map address, which 
specifies a selected node and a selected input value within 
that selected node. The output mapping is then performed 
by monitoring the broadcasts until the broadcast from the 
selected node is heard, and then extracting the selected 
input value from that broadcast and routing that input 
value to an output bit. A "connection" is thereby estab­
lished between the output and the selected input, and such 
connections may be changed simply by changing the output 
mapping selections.  
     Both the input and output bits may be either physical 
devices (14, 15, 16) or, as described in a second embodi­
ment, may be exchanged with an external system (31, 33, 
34, 35, 36, 37, 38) through a shared memory (30).  
     A Dynamic Time Division Multiple Access (DTDMA) time 
slot allocation scheme is used to synchronize transmissions 
from each node (10, 11) in a round robin fashion. Each 
node is allocated one time slot for transmission and 
maintains a current time slot value in a gap timer. The 
gap timers of all nodes are synchronized by monitoring 
a source address field in the round robin broadcasts.
