Abstract: Gegenstand der Erfindung ist eine Vorrichtung für das 
Aufdampfen von anorganischen Verbindungen mittels einer 
Photonenerzeugenden thermischen Strahlungsheizquelle in 
kontinuierlich betriebenen Vakuumbedampfungsanlagen. 
Die Vorrichtung besteht aus dem Aufdampfgut, das aus pul­
verförmigen anorganischen Verbindungen mit Schmelzpu­
nkten > 1000°C, gegebenenfalls im Gemisch mit Elementen 
mit Schmelzpunkten > 1000°C durch Vermischen unter Form­
gebung hergestellt worden ist und aus der thermischen Strah­
lungsheizquelle, wobei Aufdampfgut und thermische Strahl­
ungsheizquelle kontaktlos verbunden sind. Das Aufdampfgut 
ist als mindestens ein vorzugsweise poröser Festkörper 
ausgebildet und Festkörper und/oder thermische Strahlung­
sheizquelle sind beweglich angeordnet. Die Bewegung des 
Aufdampfgutes kann dadurch bewerkstelligt werden, daß 
dieses entweder auf einem Träger beweglich angeordnet 
oder mit einem beweglich angeordneten Trager verbunden 
ist, derart, daß der unbeweglich angeordneten thermischen 
Strahlungsheizquelle kontinuierlich unverbrauchtes Aufdam­
pfgut nachgeliefert wird. Mit Hilfe dieser Vorrichtung können 
beliebige Substrate insbesondere Folien in kontinuierlichen 
Vakuumbedampfungsanlagen mit hochsmelzenden an­
organischen Verbindungen durch einfaches oder reaktives 
Aufdampfen mit hoher Aufdampfrate gleichmäßig be­
schichtet werden.

Filed: 1987-12-03
Abstract: There is disclosed a method and additives to be 
employed in said method whereby the fouling of metal 
surfaces with copper deposits resulting from acid cleaning 
of copper alloy surfaces, be they all of the same metallurgy 
or merely elements within the overall system is markedly 
reduced by adding to the rinse of flush formulations 
commonly employed following an acid treatment, a chelating 
agent for copper, and, subsequently adding a copper 
corrosion inhibitor to the conventional neutralization 
fluid.
Patent EP-0238246-A3 (EP)
IPC: H02G15/117
Filed: 1987-03-10
Abstract: The long term water instrusion resistance of cable splice systems that use 
a gelable encapsualtn that is pressurized prior to gelation can be improved by 
providing pressurization means that maintain the pressure on the cured 
encapsulant above a given pressure  p ₂ >  p ₀, where  p ₀ is the ambient 
E 
pressure. 
Absent such pressurization means, the pressure on the encapsulant typically 
decreases with time due to creep or relaxation of nominally rigid components, 
e.g., a plymeric closure around the encapsulated splice, or vaires due to 
differential thermal contraction. The pressurization means comprises one or 
more energy storage elements, e.g., an elastic member such as a spring, or a 
volume of compressed gas. In a preferred embodiment, an elastomeric "bag" 
(23) is formed around the completed cable splice, the two havles (24, 24′) of a 
plastic closure placed around the bag, the two halves fastened together with 
spring clamps (30), liquid encapsulant introduced into the bag, and the 
encapsulant pressurized to a pressure  p ₁ >  p ₂. The spring clamps typically are 
dimensioned such that a gap exists between the two halves of the plastic closure 
for any pressure 
>/=  p ₂, at any temperature within a specified temperature range, 
at least up to the design life of the splice system. The existence of the gap 
assures that the spring clamps maintain pressure on the encapsulant within the 
closure.

Title: Circuit protection device
IPC: H02H9/04
Filed: 1987-09-22
Abstract: A circuit protection device for protecting an 
electrical circuit from a voltage transient, e.g. a 
voltage transient caused by an electrostatic discharge, 
lightning or a nuclear electromagnetic pulse, comprises 
a threshold switching element formed from an amorphous 
composition comprising germanium, selenium and 
optionally antimony, and a pair of electrodes in con­
tact with the composition.  
     The devices generally exhibit a good balance of 
physical properties including switching speed, energy 
required to latch them in their low resistance state, 
high resistance state (off) resistance, threshold 
voltage and capacitance, which enables them to be used 
successfully to protect electrical circuits from such 
transients.

Title: Method and apparatus for winding a web
IPC: B65H18/16
Filed: 1989-02-22
Abstract: The invention relates to a method and apparatus for on-machine winding of a web, in which a Pope reeling drum (10) is used, over which the web (W) to be wound passes. A reel spool (11) is driven by so-called centre drive. New reel spools (11 min ) are brought into connection with the reeling drum, after which the web (W) is conducted away from a fully wound roll to be wound onto a new reel spool. The method comprises, in combination, the following steps: an empty reel spool (11 min ) is brought into the grip of primary arms in such a way that bearing members (25) at both ends of the reel spool (11 min ) are being supported by guiding elements at each end of the reeling drum (10) in such a manner that the outer shell of the reel spool (11 min ) is not engaged with the reeling drum (10). The empty reel spool (11 min ), preaccelerated to winding speed, is brought into nip contact with the rotating reeling drum (10), the web (W) to be wounded running through the nip. Due to said nip contact, or only after it, the web breaks off or is severed by means of a double-sided adhesive tape wrapped round the reel spool (11 min ), whereby the web (W) begins to wind onto the empty reel spool (11) and the winding is continued by centre drive of the reel spool (11) and/or nip drive until the roll is fully wound, after which the above steps are repeated.
