IPC: H04J1/00
Filed: 1986-06-09
Abstract: This invention relates to a modular 
contiguous channel multiplexer (46) having one or more 
modules (41, 42) that produce an asymmetric filter 
function that is combined with responses from other 
modules (44) to produce an overall symmetrical 
response. The multiplexer (46) 
can have channels (1, 2, 4) arranged in any order of 
relative frequencies and one or more channels (3, 5) 
can be added or removed from the multiplexer (46) 
without disturbing the operation of the existing or 
remaining channels (1, 2, 4). A method of constructing 
the multiplexer (46) involves choosing a downstream 
channel first, then choosing sequentially the channel 
immediately upstream from the channel last chosen and 
choosing filters (f, f1) of each channel to meet 
certain criteria. The filters (f, f1) of each channel 
are identical to one another but are not necessarily 
identical to filters (f, f1) in adjacent channels.

Abstract: Electrically conductive paths are produced on 
a polymeric substrate (e.g. l3 or 24) by laser (e.g. ll 
or 2l) writing, i.e., by tracing desired paths on the 
substrate by a laser beam. The resulting paths comprise 
electrically conductive carbon as produced by thermal 
decomposition of substrate surface material; the paths 
can serve; e.g., as electrical interconnections akin to 
printed circuitry on a wiring board. Optionally, the 
conductivity of paths can be enhanced by electroplating 
a suitable conductor metal or alloy onto the paths.

Title: Work piece gripping device on forging manipulators
Inventor: SCHUBERT PETER
IPC: B21J13/10
Filed: 1987-08-12
Abstract: A forging manipulator has two pairs of workpiece gripping arms which operate in respective mutually perpendicular planes. Each pair of arms is operable by a respective independent actuating mechanism, so that the respective pairs of arms can accommodate workpiece dimensions. The two actuating mechanisms comprise: a common bore in the gripper carrier of the manipulator, defining two co-axial fluid pressure cylinder disposed end to end, a respective annular piston in each of these cylinders, a respective hollow piston rod extending from each piston towards the gripper arms, one of these piston rods extending within the other piston rod, and a respective wedge at the forward end of each piston rod, for operating the corresponding pair of gripper arms on movement of the piston rod. The wedges slope in opposite directions, and the pistons move simultaneously in opposite directions. This provides a very compact construction and allows material and tools to be delivered to and removed from the manipulator from the rear through the hollow piston rods.

Patent EP-0260785-A3 (EP)
IPC: H03G7/00
Filed: 1987-06-12
Abstract: An amplifier includes first and second transistors having 
emitters connected to a first current source, feedback from 
the second transistor collector to its base being supplied 
through a base-emitter path of a first Darlington pair in series 
with a first diode. A second current source is connected to 
the first Darlington pair emitter. Third and fourth transistors 
have emitters connected to a third current source with feed-­
back supplied from the fourth transistor collector to its base 
through a second Darlington pair and a second diode. The 
second Darlington pair emitter is connected to a fourth current 
source and resistively coupled to the first Darlington pair 
emitter. Constant currents are supplied to the second and 
fourth transistor collectors and an input voltage across the 
first and third transistor bases controls allocation of current 
between the first and second Darlington pair emitter-collector 
paths to produce a differential output current proportional to 
the input voltage when both Darlington pairs are on. When 
the input voltage is highly negative, the first Darlington pair 
turns off and a biasing circuit reverse biases the first diode to 
prevent the second transistor from saturating and substantially 
discharging capacitance at the base of the first Darlington 
pair. Thus, the first Darlington pair can rapidly turn on when 
the input voltage is subsequently driven more positive. When 
the input voltage is highly positive, another biasing circuit re­
verse biases the second diode to prevent the fourth transistor 
from saturating.

IPC: C07C67/00
Filed: 1987-06-16
Abstract: A process is provided for preparing 
N-acyl-aminothiophenols, e.g., N-acetyl-para-aminothiophenol, 
or aminothiophenols, e.g., para-aminothiophenol, by reacting a 
hydroxy aromatic ketone, e.g., 4-hydroxyacetophenone (4-HAP), 
with hydroxylamine or a hydroxylamine salt, to form the oxime 
of the ketone, subjecting the oxime to a Beckmann 
rearrangement in the presence of a catalyst to form the 
N-acyl-hydroxy aromatic amine, e.g., N-acetyl-para-aminophenol 
(APAP), reacting the N-acyl-hydroxyaromatic amine with an 
N,N-di(organo) thiocarbamoyl halide, e.g., 
N,N-dimethylthiocarbamoyl chloride, to form an 
O-(N-acyl-aminoaryl)-N,N-di(organo) thiocarbamate, e.g., 
O-(N-acetyl-para-aminophenyl)-N,N-dimethylthiocarbamate, 
pyrolytically rearranging the 
O-(N-acyl-aminoaryl)-N,N-di(organo)thiocarbamate to form an 
S-(N-acyl-aminoaryl)-N,N-di(organo)thiocarbamate, e.g., 
S-(N-acetyl-para-aminophenyl)-N,N-dimethylthiocarbamate, and 
hydrolyzing the latter compound to obtain the N-acyl 
aminothiophenol or aminothiophenol. The N-acyl 
aminothiophenol may be reacted with an acylating agent to form 
the N,S-diacyl-aminothiophenol, e.g., 
N,S-diacetyl-p-aminothiophenol, or may be further hydrolyzed 
to the aminothiophenol, e.g., p-aminothiophenol.
Patent EP-0279400-A3 (EP)
IPC: B29C45/30
Filed: 1988-02-15
Abstract: This invention relates to an injection molding 
system having a number of nozzles conveying melt from an 
elongated manifold to a common cavity. In the preferred 
embodiment, each heated nozzle has a melt channel which is 
offset from a central valve pin bore for conveying the 
melt to the gate. The melt channel extends through a side 
portion of the nozzle which is bolted to the side surface 
of the manifold. The bolts provide a seal against leakage 
of the pressurized melt, while at the same time allow 
slight lateral movement between the manifold and the 
nozzle. This provides for thermal expansion of the 
manifold relative to the nozzle which is accurately 
located in a well in the core The system is used 
for large cavities which require large flow volumes and 
avoids the difficulty of accurate machining of the large 
molds to provide sealing.

Title: Method for regulating access by concurrent transactions to resources
IPC: G06F9/46
Filed: 1988-02-24
Abstract: A method for regulating access by concurrent transactions to 
hierarchically-related resources distributed about a loosely-coupled 
multiprocessor system is disclosed. Lock requests are first decided by 
a local lock manager (2a...2n) 
and then by a central lock manager (1). When a single 
local lock manager (2a...2n) 
holds locks on a resource, that local lock manager 
has sole interest in the resource. While a lock manager has sole 
interest in a resource, it can acquire locks subsidiary to the resource 
without consulting with the central lock manager (1). Sole interests of 
objects are shifted dynamically for optimising local control of 
objects, thereby minimising communication and transaction wait time.

reflection terminators having an impedance that is varied by a 
diode. The resistor is placed at a point on the transmission 
line having the lowest voltage when the greatest power loss is 
realized by the phase shifter.

Title: Color cell texture
IPC: G06T15/50
Filed: 1988-12-16
Abstract: In computer image generation color definition 
is defined by a luminance or brightness (Y) component, 
an in-phase component (I) and a quadrature component 
(Q), which may be defined directly in a data base or 
derived by conversion (35) from red(R), Green(G) and 
Blue(B) component data, and which are appropriately 
processed before being (re-)converted to more 
traditional RGB components for color display control. 
Scaling and redesignating YIQ data (38) permits 
representation by fewer bits than a RGB scheme during 
processing. Also, Y values may be processed at one 
level of detail while the corresponding I and Q data 
values may be processed at a lesser level of detail. 
Translucency information may also be accommodated.
