Patent EP-0156315-A3 (EP)
Title: Circuit for testing the correct operation of a data transmission system
IPC: H04L1/24
Filed: 1985-03-21
Abstract: A circuit arrangement is provided for completely testing the operability of a data transmission facility which has a four-wire connected to a two-wire line via a hybrid and in which an echo compensation circuit is connected between the data signal output line and the data signal receiving line of the circuit arrangement. The data signals appearing on the data signal output line are supplied to the hybrid without delay as well as delayed by a fixed time interval which is selected to exceed the longest time leading to a correlation between delayed and undelayed data signals. The echo compensation circuit is driven only with the delayed data signals.
Patent EP-0166926-A3 (EP)
IPC: C08G18/62
Filed: 1985-05-11
Abstract: A radiation-curable polyethylenically unsaturated 
polyurethane resin is disclosed which cures to provide cured 
coatings possessing reasonable physical integrity at room 
temperature, a tensile modulus of less than about 10000 psi 
at -40°C., preferably less than 5000 psi at -60°C., and a high 
index of refraction, above 1.48. This polyurethane resin is 
constituted by an essentially saturated, halogenated, dihyd­
roxy-terminated linear liquid polybutadiene polymer, in 
which the halogen is preferably chlorine, reacted with an 
organic diisocyanate and an ethylenically unsaturated 
monomer carrying a single hydroxy group to form a 
diethylenic diurethane having a halogen-containing essen­
tially saturated polybutadiene backbone. Coating composi­
tions are disclosed which consist essentially of the above 
polyethylenically unsaturated diurethane having a polybuta­
diene backbone together with less than 40% of a liquid 
solvent therefor which is preferably a monoethylenically 
unsaturated liquid having a low glass transition temperature, 
and the compositions preferably include a photoinitiator 
enabling cure on ultraviolet exposure. These coatings are 
used as a buffer coating on optical glass fiber.

Title: Device and method for controlling a sluicing operation for a pile of bulk goods
IPC: B65G53/10
Filed: 1985-05-25
Abstract: An apparatus having a charging lock chamber which can be alternately closed off with respect to a supply container by a movable closure head and an annular sealing edge in opposite relationship thereto as a seat therefor, on the one hand, and from a pneumatic conveyor conduit by a flap, on the other hand, for charging a feed of particles of bulk material into the conveyor conduit, is to require inter alia only one conveyor vessel for the virtually continuous conveying of bulk material, is not to require a metering device disposed at an upstream location, and is also to be suitable for conveying pressures of around 6 bars. That is achieved in that associated with the sealing edge is at least one annular feed duct for a curtain of air which is directed towards the closure head, and that the flap which is pivoted at one end has a force storage device engaging beneath it and in its closure position bears against the substantially horizontal edge of a mouth opening (18) of the charging lock chamber. Disposed downstream of the flap is an air feed device for the conveyor conduit and the sealing edge is provided on a resilient sealing ring which extends over an annular groove and which provides a wall portion of the feed duct, which wall portion can be deformed by means of air fed thereto in such a way that said sealing ring is at a spacing from an edge of the annular groove, thereby forming a blowing gap.

Abstract: A pipelined instruction execution system including a micro­
store (20a) for storing sequences of microinstruction 
addresses associated with each macroinstruction, a nano­
store (20b) for randomly storing unique microinstructions, 
and an execution unit (30) for executing the microinstruc­
tions is provided with a no-op/prefetch apparatus (50), 
which prevents a microinstruction address, stored in the 
microstore, from accessing the nanostore and forces a no-op 
address into the nanostore when the execution unit executes 
a conditional microbranch instruction. During the execution 
of the no-op microinstruction in the execution unit, the 
no-op/prefetch apparatus permits either the next sequential 
microinstruction address following the conditional micro­
branch instruction to access the nanostore or another non-­
sequential microinstruction address to access the nanostore, 
the selection of the next sequential microinstruction 
address or said another non-sequential microinstruction 
depending upon the outcome of the execution of the condi­
tional microbranch instruction by the execution unit.

Title: Processing paper and other webs
IPC: B41F27/12
Filed: 1987-05-13
Abstract: A printing apparatus has an array of cartridges (40,41,42) for printing a web (2) of e.g. paper passing through the array, and one or more units (48,49) containing printing medium. The cartridges (40,41,42) each are capable of transferring the printing medium from the units(s) (48,49) to the web (2). The unit(s) (48,49) and the cartridges (40,41,42) of the array are relatively movable, to allow the unit(s) (48,49) to interact successively with at least two of the cartridges (40,41,42). In this way it is possible to change printing from one cartridge (40,41,42) to another, allowing changes to be made to what is printed, without halting the movement of web (2) significantly. The present invention also proposes that the cartridges (40,41,42) may have printing cylinders (43,44,45,46) of different sizes, and furthermore that a mobile unwind stand may be used to move web material to the printing apparatus, and the web output from the printing apparatus processed by sheet folding techniques.

Abstract: An electroless copper plating bath is improved so 
as to facilitate its regeneration in an electrodialysis 
cell. The bath includes elevated amounts of an added 
salt, preferably as Na salt. The elevated sodium ion 
level serves as additional counter-cation to hydroxyl 
ion which is produced at the cathode of the 
electrodialysis cell. The excess anion from the added 
salt increases the rate of out-migration of by-products, 
such as formate ions and sulfate ions, relative to 
hydroxyl ions through an anion permselective membrane.

mounted. The heating element (15) has two generally pa­
rallel legs (17,18) and a bight portion (19). A well 
(40), mounted at one end in the mounting plug (2), pro­
jects along and substantially parallel to the legs (17, 
18) in heat exchange relation therewith. A thermal cutoff 
(50) in the well (40) is electrically connected in series 
with one end of a two-ended electric resistance element 
in the sheathed heating element (15). A thermally con­
ductive bridge is mechanically and thermally connected to 
and between the legs (17, 18) of the sheathed heating 
element (15) and the well (40) containing the thermal 
cutoff (50), which is mounted against the inner wall of 
the well (40). The legs (17,18) of the sheathed heating 
element (15) are bent back upon themselves, and a bracket 
(37), connected to the two reaches of at least one leg, 
permits relative axial movement but prevents lateral move­
ment of the reaches of the legs (17,18) with respect to 
one another. The mounting plug (2) is made of solid copper 
or copper alloy, as is the sheath (16) and well (40). A 
molded closure (68) has holes through which terminal pin 
(47) from the thermal cutoff (50) and a terminal pin (30), 
from one end of the resistance element (15), extend. The 
molded closure (68) has a boss (74) with a blind hole (75) 
into which a terminal pin (29) connected to the other end 
of the heating element (15) and to another terminal pin 
(49) of the thermal cutoff (50), extends.

Abstract: Die Erfindung bezieht sich auf ein Sprenggeschoß zur Split­
tererzeugung.  
     Bekannte Sprenggeschosse, bzw. Gefechtsköpfe sind zur Ge­
währleistung der Abschußfestigkeit im Heckbereich relativ 
dickwandig ausgebildet. Dies führt bei Sprengzerlegung zu 
einer gewissen Splittergröße, bzw. zu einer sehr unter­
schiedlichen Splittercharakteristik -von Geschoßhülle und 
Geschoßboden.  
     Um derartige Nachteile zu vermeiden, wird erfindungsgemäß 
ein Splittergeschoß, bzw. ein Gefechtskopf vorgeschlagen, 
das/der einen Geschoßboden von etwa der gleichen Stärke 
wie die Geschoßhülle aufweist und daher eine gleichmäßigere 
Splittercharakteristik besitzt. Die Wandstärkenverminderung 
im Geschoßheckbereich wird unter Reduzierung der Empfind­
lichkeit gegen radiale Gasdruckbeaufschlagung dadurch er­
reicht, daß die Geschoßhülle 12 im Heckbereich bis an den 
Geschoßboden 38 reichend zylindrisch ausgebildet, das Füh­
rungsband 40 in direkter Nähe zum Geschoßboden 38 ange­
ordnet und der Geschoßboden 38 kalottenförmig nach außen 
ausgewölbt ist.
