Patent EP-0160857-A3 (EP)
IPC: B29C48/07
Filed: 1985-04-13
Abstract: Mehrschichtig zusammengesetzte Rohlaufstreifen für 
Luftreifen werden in Einrichtungen mit zwei und mehr nach 
einem gemeinsamen Mundstück fördernden Strangpressen 
als einheitlich zusammenhängende Profilstreifen hergestellt, 
wobei die Teilströme verschiedener Elastomermischungen 
nach dem Ablaufen von einer feststehenden Trennzunge in 
einer dem Mundstück unmittelbar vorgeordneten Vorschab­
lone in haftende Verbindung miteinander zusammengeführt 
werden. Die Erfindung stebt eine verbesserte Haftung der 
Teilströme aneinander an, und sie erreicht dies durch 
Vergrößern der Haftflächen und durch Erzeugen von Relativ­
bewegungen der nebeneinander fließenden Stromfäden in 
dem Grenzflächenbereich.  
     Nach einer Ausführungsform der Erfindung kann dies 
durch Ausbilden der Oberflächen der Trennzunge mit auf­
einanderfolgenden Erhöhungen und Vertiefungen und nach 
einer anderen Ausführungsform durch Ausbilden der Vor­
derkante der Trennzunge mit aufeinanderfolgenden Aus­
nehmungen und Vorsprüngen erreicht werden.

Title: High speed data bus structure and system
IPC: G06F13/40
Filed: 1982-10-19
Abstract: In a very high speed data bus system for communication among the various functional units that may constitute a large computer system each functional unit has an associated port which operates to accept all related information that makes up a communication, or if this cannot be done, to accept none of the information. To implement the indivisibility of transfers, the control logic for each port includes screening circuitry responsive to the state of the port's input buffers, and further responsive to flags from the functional unit for selectively accepting or rejecting bus information, and further includes screening constraint circuitry to ensure that the port accepts all or none of the information that makes up the transfer. Depending on the flag, the rejection may be total, or may apply only to a designated class of transfers.

Patent EP-0209112-A3 (EP)
IPC: G02F1/1362
Filed: 1986-07-15
Abstract: Light blocking spacer material is disposed so as to at 
least partially cover the data and/or gate lines in a variety of 
liquid crystal display (LCD) devices. The material prevents 
spurious visual information from being displayed as a result 
of high RMS supply voltages applied to the data lines, such 
voltages acting to switch liquid crystal material at inoppor­
tune times and to thus degrade the displayed image. The 
light blocking material also enhances the displayed image 
by acting as a spacer between the front and back LCD de­
vice panels to insure uniform cell spacing. Light blocking 
material is also employed at the same time to prevent light 
from reaching light sensitive thin film field effect transistors 
(FETs) which operate to switch each cell or to establish gray 
levels therein. The light otherwise has a tendency to dis­
charge the LCD cell, also hampering device function.
