Title: Injection molding methods, injection molding apparatus and injection nozzle devices for use in molding multiple-layer articles, and multiple-layer injection molded articles
IPC: B29C45/16
Filed: 1984-04-11
Abstract: For co-molding a plurality of articles from a plurality of 
polymeric materials, a preferred molding apparatus has a 
plurality of valve-controlled co-injection nozzles (296) and 
injection cavities (102). The polymeric materials (A to E) 
are melted and fed from their sources (202, 204, 206) by 
screw extruders (214, 216, 218) to a set of rams (232, 234, 
252, 260, 262) which appropriately pressurize and move 
streams of the polymeric materials to feed block (296) each 
associated with or forming part of a respective nozzle (296) 
for injection into the related cavity (102). The streams 
leaving the rams (232, 234, 252, 260, 262) are conveyed along 
respective runner ducts (220, 222, 257, 258) to a runner 
extension member (276) in a runner block (288), and in the 
runner extension each material stream is divided into a 
plurality of branch streams. Each branch stream is ducted to 
flow splitters in the runner block (288) for further division 
into plural feed streams equal in number to the number of 
nozzles (296), and the separate feed streams are then fed one 
to each nozzle (296). The apparatus is configured such that 
for each material, the plural feed streams reach their 
respective nozzles (296) after passage along ductings of the 
same length and geometry to ensure that the streams enter 
their nozzles as nearly as possible in the same condition, 
ready for injection. Each nozzle (296) receives the 
polymeric materials (A to E) as separate feed streams and 
combines them appropriately into a plural-layer 
plural-material stream for injection. The nozzles all have 
pin and sleeve valves (800, 834) to control admission and 
flow of the different materials to their central channels 
(240) wherein the combined stream is formed. Valve operation 
is under microprocessor control (2040) and the valves - which 
are effectively substantially identical - are coupled to 
common valve actuating cams (850, 856) for operation in 
 
 
unison, so that at any instant in the molding cycle the 
combined streams formed in the nozzles (296) for injection 
are as near as possible identical to one another. By 
appropriately controlling the pressures of the polymeric 
material streams and by appropriately controlling the timing 
of valve operating movements, precise control is obtainable 
whereby e.g. internal layers of the injected articles are 
positioned where best suited depending on the service 
requires of the articles.  
     The method and apparatus are applicable to the 
production of injection or injection blow molded articles 
such as containers for commestibles and beverages.

Title: Rnase l inhibitor as a marker for virus infections
IPC: G01N33/573
Filed: 1988-03-02
Abstract: HIV-directed inhibitors of the natural 2′-5′A 
antiviral defense pathway, diagnostic procedures and 
materials, and modalities for treating viral 
disorders are described. HIV-induced inhibitors of 
RNase L in patients with lymphadenopathy (LAS), 
AIDS-related complex (ARC) and acquired immune 
deficiency syndrome (AIDS) were isolated and 
identified. Functional 2-5A is not able to activate 
RNase L in the peripheral blood mononuclear cells 
(PBMC) in these patients; endogenous dsRNA, 
especially mismatched dsRNA, activates 2-5A 
synthetase which results in an increased 
concentration by endogenous 2-5A.

verdrängt wird. Das Werkstück (W) wird mit einer axialen 
Vorschubgeschwindigkeit von mindestens 3 mm pro 
Werkstückumdrehung, bei hohlen Werkstücken vorzugsweise mit 
mindestens 5 mm pro Werkstückumdrehung, entlang seiner 
Werkstückachse (A) in Vorschubrichtung (II) bewegt. Die sonst 
bei gewissen Materialien auftretenden Schwierigkeiten können 
dabei vermieden werden, wobei auch die 
Produktionsgeschwindigkeit neben der Qualität gesteigert 
werden kann. Das Verfahren ist auf Werkstoffe und Werkstücke 
anwendbar, die bislang als sehr schwer bearbeitbar galten. 
Bei hohlen Werkstücken, welche eine Innenprofilierung auf 
einem Dorn erfahren, wird das so mit hohem axialen Vorschub 
vorgeschobene Werkstück vorzugsweise auch beim Rückschieben 
gewalzt. Der Rückschub sollte höchstens gleich gross wie der
