Patent EP-0281123-A3 (EP)
IPC: H04R3/14
Filed: 1988-03-03
Abstract: Passive Lautsprecherboxen mit Umschaltern an einzelnen 
Weichenzweigen, meist im Mittel- und/oder Hochtonzweig, 
sind bekannt. Sie erlauben Pegelangleichungen an die 
Raumakustik und/oder geschmackliche Entzerrungen. Es sind 
auch Boxen, die von aktiven Netzwerken angesteuert werden 
bekannt, die zusätzliche passive, festinstallierte Fre­
quenzweichen enthalten und so "Passivbetrieb" ermögli­
chen. Der Erfindung lag die Aufgabe zu grunde, die 
Frequenzweiche einer Lautsprecherbox so auszustatten, daß 
eine Änderung des Gesamtcharakters der Lautsprecherbox 
zur Anpassung an unterschiedliche Marktgewohnheiten 
und/oder individuelle Kundengeschmacksrichtungen vorge­
nommen werden kann.  
     Die Lösung sieht vor, daß die Frequenzweiche als 
Mehrfachfrequenzweiche ausgebildet ist, deren sämtliche 
unterschiedliche Weichenzweige mittels eines zentral 
gesteuerten mehrpoligen Umschalters (S) wahlweise alter­
nativ an die Bereichs-Lautsprecher (TT, MHT) anschießbar 
sind, wobei für jeden Weichenzweig jeweils zwei korres­
pondierende Umschalterkontakte in zwei verschiedenen 
Schalterebenen (A, B) vorgesehen sind und diese paarweise 
abwechselnd geschlossen werden.  
     Mehrfach-Frequenzweichen, passiver Art, für Lautsprecher­
boxen.

Title: Needle valve nozzle for injection moulds
IPC: B29C45/28
Filed: 1989-03-09
Abstract: A valve which serves to admit hardenable metallic, plastic or other material into the die of a molding machine has a housing with a centrally located passage for a reciprocable needle-like valving element, an inlet for hardenable material at one side and adjacent one end of the passage, an outlet which is coaxial with the other end of the passage, an eccentric chamber disposed at the one side of the passage and communicating with the inlet, and an elongated gap which establishes communication between the chamber and the passage. The valving element is movable between an extended position in which it seals the gap from the outlet and a retracted position in which the gap admits hardenable material into the passage so that the admitted material can flow toward and through the outlet. The housing surrounds the valving element in the region of the gap along an arc of more than 180 DEG .

Title: Apparatus for attaching a strand-like drainage element in a press
IPC: B30B9/26
Filed: 1989-08-24
Abstract: The apparatus for attaching a drainage element (8) in a press for eliminating liquid from solid pressed material comprises a turn-lock fastener (16) by means of which the ends of the drainage element (8) are each detachably fastened to a pressure plate (5, 6) limiting the pressing chamber (7).

Title: Process for producing silicon carbide whiskers
IPC: C30B29/62
Filed: 1989-11-15
Abstract: A process for producing silicon carbide whiskers 
in which a source of silica is mixed with a residual oil 
or crude petroleum and the resultant mixture is heated in 
a substantially nonoxidizing atmosphere at temperatures suffic­
iently high to carbonize the residual oil or crude petroleum, 
thereby forming an intimate mixture of carbon and silica. 
The intimate mixture is then heated in a nonoxidizing atmosphere 
in the presence of a seeding component comprising an element 
selected from boron, the rare earths, Group IA, Group IB, 
Group VB, Group VIB, Group VIIB and Group VIII of the Periodic 
Table of Elements at temperatures sufficiently high to induce 
the reaction between carbon and silica to form silicon carbide. 
The resultant silicon carbide product will contain a relatively 
high concentration of silicon carbide whiskers.
Patent EP-0377973-A3 (EP)
Title: Sensor array and illumination system for a large depth-of-field bar code scanner
IPC: G06K7/10
Filed: 1989-12-12
Abstract: An improved sensor array and illumination scheme for a bar 
code scanner use a modified Scheimpflug arrangement optical system 
that simplifies signal processing. The preferred embodiment 
includes a detector array (131) comprising a multi-element array 
of photosensors (311) positioned in one Scheimpflug plane (141) and 
an illumination beam in the form of a sheet of light along the 
other Scheimpflug plane (119). The detector array (131) has a 
plurality of elements having a long axis and a short axis, with the 
long axis of the elements arranged substantially perpendicular to 
the image of the illuminated strip of the bar code tag. The 
projection of the long axis of the elements of the array (131) onto 
the other Scheimpflug plane (119) defines the working range of the 
optical system. So long as the bar code tag intersects the 
illumination beam within the working range, the image of the 
illuminated strip of the bar code tag will be substantially in 
focus across the elements of the detector array (131). Filtering 
allows substantially only the light from the illuminated strip to 
reach the detector array (131). Thus, substantially all of the 
light that reaches the detector array (131) is useful signal, and 
all the output data from the array during a bar code scan is 
relevant. The output signal from the array can be processed with 
conventional digitizing and decoding circuitry with audio signal 
processing techniques.
Patent EP-0375258-A3 (EP)
IPC: H01L21/304
Filed: 1989-12-13
Abstract: An improvement in silicon wafer flatness is obtained by reducing the 
time spent in polishing the wafer. After a conventional lapping operation, the wafer 
is coated with an etch resistant coating, typically silicon nitride. A polishing step 
removes the nitride coating on the flat surfaces of the wafer, but leaves a nitride 
coating on the sides of pits that are formed in the lapping operation. The wafer is 
then etched, typically in KOH, to remove the silicon surface to below the depth of 
the pits. The undercutting of the nitride coating removes the pits, or leaves relatively 
small protrusions in their place. The protrusions may be removed by a short 
polishing operation. Other wafer types and etch-resistant materials are possible. 
Integrated circuits are typically formed on the wafers by lithography techniques that 
advantageously utilize the improved flatness.

Title: Article manufactured by melt extrusion of a thermoplastic resin composition; thermoplastic resin composition
IPC: C08L67/02
Filed: 1990-01-26
Abstract: The invention relates to an article manufac­
tured by extrusion from a thermoplastic resin com­
position. The resin composition comprises a polybutylene 
terephthalate resin and a special type of alkylmethacry­
late - butadiene - styrene interpolymer.  
The melt strength of the polybutylene terephthalate 
resin is considerably improved by the addition of the 
interpolymer. As a result of the improved melt strength 
it is possible to obtain extruded articles, like tubes, 
having a small wall thickness.
