Title: Method and device for extrusion, particularly of edible masses
IPC: B29C48/94
Filed: 1987-07-09
Abstract: The mass to be extruded is forced into an extrusion duct (die) (1) so as to make it emerge in the extruded state from the outlet end (3) of the duct in a direction (2) generally-axial of the duct itself. An annular flow of fluid is generated around the outlet end (3) of the extrusion duct (1), oriented in an axial direction relative to the extrusion duct (1), and surrounds the extruded mass, preventing it from bending accidentally. The extruded mass is divided into pieces by a cutting operation (9) carried out within (7) the zone in which the annular flow of fluid acts.

Title: Charge amplifying trench memory cell
IPC: H01L27/108
Filed: 1989-02-06
Abstract: A charge amplifying memory cell and its method 
of making based on trench technology. A 
trench is formed which reaches through an n-type well 
region (32) to a p⁺-type substrate (30). A triple layer 
(36, 38, 40) is formed on two sidewalls of the trench 
consisting of two capacitive insulating layers and a 
intermediate p⁺ polysilicon layer. The trench is then 
at least partially filled with a conductor, such as 
polysilicon (42), facing the triple layer. Thereby, 
the intermediate polysilicon layer acts as a charge 
storage node with capacitance to both the substrate and 
the polysilicon filling the trench. The insulating 
layer facing the well is opened with a contact hole 
near its top so that a p⁺ transistor drain (44) is 
formed in the adjacent well by diffusion from the 
polysilicon through the contact hole. A p⁺ transistor 
source (50) is doped into the well with a gate region 
between it and the drain to provide a write transistor. 
A p+ region (46) is also formed adjacent a sidewall of 
the trench other than the one containing the contact 
hole so that a read transistor is vertically formed in 
the n-type well between it and the substrate. The 
intermediate p⁺ polysilicon layer acts as the electrode 
of this read transistor, whereby stored charge is 
amplified by the read transistor.

IPC: D21F1/00
Filed: 1989-06-07
Abstract: The invention relates to a double-layer fabric as the wire screen for the wet end of a paper machine.

Abstract: Der Transmix-Schweißschutzvorhang dient der Abschirmung von 
Arbeitsplätzen in Werkhallen oder im Freien, an denen Gas­
schweiß - oder Lichtbogenschweißarbeiten durchgeführt werden. 
Um an ein und demselben Arbeitsplatz sowohl Gasschweiß- wie 
auch Lichtbogenschweißarbeiten ausführen zu können und um 
dabei den Schutzvorschriften Rechnung zu tragen, ist der 
Transmix-Schweißschutzvorhang so gestaltet, daß er bei 
variablen Abständen nach oben oder unten einen mittleren, un­
durchsichtigen, in der Breite und Länge ebenfalls variablen 
Teil (3) enthält, der Außenstehende vor der beim Lichtbogen­
schweißen entstehenden Strahlung schützt.  
Der obere und untere Teil des Schweißschutzvorhanges besteht 
aus durchsichtigem Material (2), wie es bisher allein beim Gas­
schweißen verwendet wurde. Dieses durchsichtige Material er­
möglicht Außenstehenden teilweise den Einblick in den ab­
geschirmten Arbeitsplatz, wodurch Unfälle oder sonstige 
Ereignisse - auch beim Elektroschweißen - von außen erkannt 
werden können.  
Während bisher Elektroschweißarbeiten nur hinter voll­
ständig undurchsichtigen Vorhängen möglich und durchführbar 
waren, die keinerlei Einblick von außen gestatten, kann - be­
dingt durch die Einsehmöglichkeit von außen - bei Arbeits­
unfällen o.ä. im Rahmen der Durchführung von Elektroschweiß­
arbeiten schnellstmögliche Hilfe und Unterstützung erbracht 
werden.

Title: Method and device for stacking stackable elements in groups
IPC: B65G57/112
Filed: 1989-08-03
Abstract: For the stack-wise collation of stackable elements (14) supplied in a single row, the latter are gripped separately and are raised to oblique moving tracks (18) during their further movement in accordance with their respective stacking height. Subsequently, the stackable elements (14) of each stacking group are slowed down from the bottom to the top in succession and in this way moved above one another and stacked. In each case a plurality of stackable elements (14) of a stacking group (52, 54) or adjacent stacking groups can be raised simultaneously. The stacking of the adjacent next stack is begun already before stacking of one stack has been completed. This continuous, interleaved manner of operation permits a very fast collation of the stackable elements (14), which are, moreover, handled in an extremely gentle manner. <IMAGE>
