Title: Polymer-asphalt mixing process
IPC: C08J3/00
Filed: 1988-12-13
Abstract: The present invention relates to a two stage 
process for the incorporation of plastic and 
ethylene-propylene rubber into asphalt. In the first 
mixing stage, a rubber-rich masterbatch is prepared by 
mixing asphalt, plastic and the rubber. In the second 
stage of mixing, additional asphalt is mixed with the 
masterbatch. The first stage is completed in polymer 
mixing equipment while the second stage is completed in

oscillator signal are employed. The signal developed by the 
first receiver channel is used to drive in phase (I) and 
quadrature (Q) counters of a Costas-loop, which phase-locks to

Title: Apparatus and method for processing simultaneous radio frequency signals
IPC: H03H17/02
Filed: 1989-06-02
Abstract: In a signal processing system, a weighting function is applied 
to incoming signal pulses in response to a signal edge detector 
(48). A weighting function is applied both to the detected 
large signal pulse and to the time surrounding the signal 
pulse within a window but at different times so that small 
signals, if they occur overlapping in time with the leading 
or trailing edge of the detected large signal, are weighted 
independently of the large signal. The weighting functions 
are multiplied with the incoming signals and then sent to 
conventional signal processing apparatus (58).

Title: A method for detecting and avoiding erroneous decombining in combining networks for parallel computing systems
IPC: G06F15/173
Filed: 1989-06-21
Abstract: A method to detect and avoid erroneous message de­
combining in the switching nodes of message combining 
multistage interconnection networks used to connect the 
multiple processors to the multiple memory modules of 
the shared memories used in parallel computing systems. 
The method assigns a unique ID to each switch and tags 
each combined message with it. This ID is also tagged 
to the reply messages. During decombining the 
message's ID is matched with the switch's ID, if they 
do not match the message is not decombined. According 
to a further feature of the invention, it is possible 
to provide sufficient information in the ID field to 
allow a routing error to be detected.

IPC: F02F1/42
Filed: 1989-12-20
Abstract: An intake manifold (16) and cylinder head intake 
passageway (34) for an air-cooled internal combustion 
engine (10). The manifold is substantially S-shaped 
and generally vertically oriented and communicates a 
carburetor (18) having a horizonal bore (72, 80, 82) 
with an overhead valve cylinder head (14) having a

elevation above that of the carburetor. The manifold 
has a turbulence inducing ridge (94) at the entrance 
from the carburetor and the cylinder head intake 
passageway has a similar ridge (120) at the entrance 
from the manifold. Each elbow bend in the manifold and 
in the cylinder head passageway is provided with a flat 
area (100, 108) at the outside curve of the bend which 
prevents puddling of fuel in the arcuate section of the 
bend and which causes any fuel which collects there to 
be spread out in a thin film which is then reintroduced 
into the air stream by a wedge-shaped ridge (102, 112) 
transverse to the flat area and rising therefrom to a 
ridge peak.

Title: Flame arrester
IPC: A62C4/02
Filed: 1989-12-22
Abstract: A flame arrester (1) for a pipe line (5) is provided 
comprising a detonation attenuator (4) mounted within an 
arrester chamber (13) between a quenching element (3) and a 
backflash flame inlet (12). The attenuator (4) is generally cup-­
shaped, aligned with the inlet, of greater diameter than the 
inlet but of lesser diameter than the arrester chamber, and 
is positioned close to the inlet so as to circumscribe it. 
The major portion of the high pressure central portion of a 
detonation wave generated by a backflash is received by the 
cup and reflected back into the pipe. Some of the detonation 
wave passes around the cup and impinges on the arrester 
element - however it has been delayed sufficiently to ensure 
complete quenching of the flame front in the element.

Title: Process for preparing a foodstuff from cereals and its use
IPC: A23L7/20
Filed: 1990-02-01
Abstract: Cereal is softened in water. Subsequently it is allowed to germinate, that is for 3 to 7 days, preferably 5 to 6 days, in particular 5 days for rye and 6 days for wheat, inclusive of the softening time. After the germination process the moist, fully enzymically active, germinated cereal is heated to 40 to 70 DEG C, preferably 50 to 60 DEG C, in particular about 55 DEG C and subjected to  heat treatment at this temperature over a time period of 8 to 24 hours, preferably 10 to 14 hours, without the moisture content being reduced. Subsequently, the cereal thus treated is if desired dried under mild conditions. The grains thus obtained have good swelling properties and, as an additive in the production of bread or baked goods, improve their flavour, moistness and freshness retention capacity. Moreover the product can also be used as a flavour intensifier.

Title: "unknown" response processing in a diagnostic expert system
IPC: G06N5/04
Filed: 1990-03-21
Abstract: A diagnostic expert system incorporating a cause-effect 
graph is disclosed in which "yes", "no" and "unknown" are 
valid possible responses to a query. Each node in the graph 
is assigned a local decision factor LDF) based on a given 
node's desirability for selection during best-first search 
and a collapsed decision factor (CDF) based on the average 
values of the LDFs for all its daughter nodes. For a 
current node being processed, a list of all its daughter 
nodes is obtained and examined to remove all daughter nodes 
that have been visited before in the current transition and 
all daughter nodes which have prerequisites that are not 
met. Then, the daughter node with the largest LDF is 
selected and its test function is executed. If the user 
response is "yes", the daughter node is made the current 
node, and a list of its daughter nodes is obtained to 
continue the process. If the user response is "no", the 
daughter node is added to the closed list, and the process 
continues with the next daughter node of the current node. 
If the user response is "unknown", the daughter node's CDF 
is compared with the LDFs for the other daughter nodes of 
the current node which are not on the closed list and which 
have their prerequisites met. If the CDF is larger than all 
the LDFs, the daughter node is made the current node to 
continue the process; otherwise, the daughter node with the 
largest LDF is selected, and its test function is executed 
to continue the process.

Title: Multi-cylinder dryer for paper machine with supported draw of web
IPC: D21F5/04
Filed: 1990-02-15
Abstract: A multi-cylinder dryer for a paper machine, comprising several drying 
groups (101...600) placed one after the other, wherein drying cylin­
ders are placed one above the other in stacks, preferably in vertical 
stacks. In subsequent groups the web (W) is passed from one drying 
cylinder onto the next drying cylinder by means of single-wire draw 
so that the drying cylinders (0,10,20,30,40,50,60) in the single-­
wire draw groups are placed outside the loops of their drying wires 
(1,11,21,31,41,51,61). The web (W) is passed as a supported draw 
from one single-wire group to the next single-wire group by using at 
least two transfer-suction rolls (4,12,14,22,24,32,34,42,44,52). 
The first transfer-suction roll is placed inside the loop of the 
drying wire of the former single-wire draw group. The last transfer-­
suction roll is placed at the proximity of the first suction roll 
inside the loop of the drying wire of the latter single-wire draw 
group at the proximity of the first drying cylinder. The transfer 
of the web (W) from one wire group to the next wire group takes 
place substantially all the time supported by a drying wire. Thereat 
the web is subjected to a difference in pressure that keeps it in 
contact with the drying wire, as a rule a negative pressure effective 
from the drying-wire side.
