Patent EP-0295389-A3 (EP)
IPC: C01F7/16
Filed: 1988-04-20
Abstract: Die Erfindung betrifft ein Verfahren und eine Vorrichtung 
zur Herstellung von Keramikpulvern.  
     Aufgabe der Erfindung ist es, ein Verfahren zur Herstellung 
von feinen Keramikpulvern mit Teilchengrößen unter 5 µm zu 
schaffen, bei welchem keine ultrafeinen Pulver entstehen und 
bei welchem größere Temperaturschwankungen in der ersten 
Heizzone aufgrund von Schwankungen bei der Zudosierung der 
Lösung bzw. der Suspension vermieden werden.  
     Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß das 
Versprühen der Lösung oder der Suspension und/oder das Ver­
dampfen des Lösungsmittels mit Hilfe eines zuvor auf eine 
Temperatur im Bereich von 500° C bis 800° C erhitzten Gases 
erfolgt, die Partikelchen zur Reaktion und zumindest teil­
weisen Kalzination auf 900° C bis 1000° C erhitzt werden und 
in einer Abscheidezone auf eine Temperatur zwischen 150° C 
und 500° C wieder abgekühlt werden.

Patent EP-0319998-A3 (EP)
Title: System for carrying out connection management control of ring network
IPC: H04L12/437
Filed: 1988-12-09
Abstract: At least three control patterns are used for a 
connection management control of nodes (1) in a ring 
network, each node determining a changeable communica­
tion status in accordance with a communication status of 
the own node and the nature of the control pattern 
received from an upstream node. The own node transmits 
one of the control patterns, selected in accordance with 
the changes in the communication status, to the 
downstream node. The control patterns indicate respec­
tive conditions of the own node so that the communica­
tion enable status of the ring network, as a whole, can 
be autonomously established by the nodes per se without 
employing a monitor node or supervisory node.

Title: Triangle waveform generator for pulse-width amplitude multiplier
IPC: H03K4/06
Filed: 1988-06-22
Abstract: A triangle waveform generator for a pulse-width amplitude multiplier includes a digital-to-analog converter and a charge transfer network. Clocked signals applied to the converter, which includes a resistor chain for providing a set of different potentials, sequentially select ones of the potentials and supply two of them to the charge transfer network. The network weights each of the potentials received, then combines them at an output node. By employing appropriate clocking of the converter, a triangular waveform having a plurality of discrete steps results.

Title: Yarn, method for making it, and nozzle to put the method into effect
IPC: D02G1/16
Filed: 1989-04-07
Abstract: A yarn, in particular a sewing yarn, is described which has at least one first yarn component in the form of a core and at least one second yarn component fluidised with the first yarn component. The second yarn component is arranged predominantly in the outer region, based on the finished yarn. The fluidised yarn has between about 0.02% by weight and about 20% by weight of granular particles which are incorporated in the yarn cavities and/or arranged on the outside of the yarn. The granular particles have a particle diameter between about 4  mu m and about 400  mu m. A process for the production of the yarn is also described, in which at least one first yarn component is fluidised with at least one second yarn component in a turbulent fluid stream, the first yarn component being wet with an aqueous dispersion or suspension of the granular particles, the density of which is greater than 1 g/cm<3>. In a further process, a mist consisting of finely divided water droplets and granular particles, and/or a dust of the granular particles, is added to the fluid stream, the granular particles having a density > 1 g/cm<3>. A nozzle for carrying out the process is also described, which nozzle is provided with a fluidising chamber and an outlet orifice for the finished yarn, the fluidising chamber and the outlet orifice consisting of ceramic or having a ceramic covering. <IMAGE>
Patent EP-0345686-A3 (EP)
Title: Pressure swing adsorption apparatus and process for recovery of oil-soluble vapors
IPC: B01D53/04
Filed: 1989-06-05
Abstract: In a pressure swing adsorption system used to recover an oil-soluble solvent, monomer or hydrocarbon vapor such as 1,1,1-trichloroethane or styrene from a gaseous stream such as air, an oil-sealed vacuum pump may be used without substantial absorption of vapor into the oil if the oil in the pump is heated to a temperature substantially above the dew point of vapor in the gas stream leaving the pumps. Prior to this invention, oil-sealed vacuum pumps cannot be used to recover oil-soluble compounds because the vapor dissolves in the oil as the desorbed vapor and backpurge gas pass through the pumps. The thinning of the oil hurts the lubrication and seal within the pump and floods the pump.

Abstract: A bag-filling device is provided with clamping devices retaining the initially flat bags in the region of the side edges of their opening rims, and with suckers engaging on opposite sides in the region of the opening rims and pulling these sides apart, and with a filling nozzle. In order to prevent the powdery material from adhering to the bag walls in the region of the engagement of the suckers, a transverse strip (22) of elastomeric material is in each case provided at least beneath the sucker(s) (21, 21') on each side on the sucker supports (17, 17'), which strip presses the pulled-apart edge regions of the bags (14) tightly against the side walls of the filling funnel.

Title: A cross-point contact-free floating-gate memory array with silicided buried bitlines
IPC: H01L29/788
Filed: 1989-10-27
Abstract: A contact-free floating-gate non-volatile memory cell 
array (1) and process with silicided NSAG bitlines (2,4) 
and with source/drain regions (SD) buried beneath 
relatively thick silicon oxide (5). The silicided 
bitlines (2,4) have a relatively small resistance, 
eliminating the need for parallel metallic conductors 
with numerous bitline contacts. The array (1) has 
relatively small bitline capacitance and may be 
constructed having relatively small dimensions. Isolation 
between wordlines (13) and between silicided bitlines 
(2,4) is by thick field oxide or by P/N junction or trench 
isolation. Wordlines (13) may be formed from silicided 
polycrystalline or other material with low resistivity. 
Coupling of programming and erasing voltages to the 
floating gate (8) is improved by extending the gates (8) 
and (10) over the thick field oxide and perhaps by using 
an insulator with relatively high dielectric constant 
between the control gate (10) and the floating gate (8). 
The resulting structure is a dense cross-point array of 
programmable memory cells.

Title: Jet wiping nozzle
IPC: C23C2/38
Filed: 1989-09-12
Abstract: In the gas jet wiping of galvanised wire strip or tube, 
the gas jet wiping nozzle 10 and, preferably a reactive gas 
containment vessel 30 used for modifying the surface 
coating on the wire 16, are made in two or more non-annular 
parts 17,18;31,32 which when abutted together form an 
annulus. The parts may be releasably held together in their 
abutted annular form until the wire 16, strip or tube 
requires to be rethreaded, then the parts 17, 18;31,32 can be 
separated from one another transversely of the direction of 
travel of the wire 16, strip or tube through the nozzle 10 or 
containment vessel 30. The threading of the wire 16, strip 
or tube through an annular nozzle 10 or containment vessel is 
thereby avoided.
