Patent EP-3886090-A3 (EP)
Inventor: ZAMORA ESQUIVEL JULIO
IPC: B60R16/023
Filed: 2020-12-11
Abstract: Techniques are disclosed to use existing vehicle speakers alone or in conjunction with other sensors (e.g. SRS sensors and/or microphones) that may already be implemented as part of the vehicle to identify acoustic signatures. Suitable low-cost and widely available hardware components (e.g., relays) may be used to modify the vehicle's existing speakers for a bi-directional mode of operation. Moreover, the vehicle's existing of audio amplifiers may be used to amplify signals collected by the speakers when operating in "reverse," and process these collected signals to determine vehicle state information.

Inventor: GUO BINGQING
IPC: H04L45/00
Filed: 2021-11-12
Abstract: This application provides a communication method and apparatus, so that a problem that a packet cannot be further processed because a segment identifier is unavailable can be resolved, and communication reliability is improved. The communication method and apparatus may be applied to a broadband access system, a metro access system, a backbone network system, LTE, or NR. The method includes: A first network device receives a first packet. The first packet may include a first segment identifier and a second segment identifier. If the first segment identifier is unavailable, the first network device obtains the second segment identifier based on the first segment identifier, and updates a destination address in the first packet with the second segment identifier, to generate a second packet. In this way, the first network device can process the second packet based on the second segment identifier.

IPC: C07F7/20
Filed: 1982-02-09
Abstract: Gegenstand der vorliegenden Erfindung ist ein Verfah­
ren zur Reinigung von Hexamethylsisiloxan, das durch 
Toluol oder andere Lösungsmittel, die sich destillativ nicht 
vollständig von Hexamethyldisiloxan abtrennen lassen, ver­
unreinigt ist. Das Verfahren läßt sich in gleicher Weise zur 
Reinigung von Hexamethyldisiloxan einsetzen, das durch 
andere Substanzen verunreinigt ist. Es basiert auf der 
Tatsache, daß Hexamethyldisiloxan mit Acetonitril ein bisher 
unbekanntes Azeotrop bildet. Dieses Azeotrop bildet eine 
schwerere, acetonitrilreiche Phase und eine leichtere, hexa­
methyldisiloxanreiche Phase, die miteinander nicht misch­
bar sind. Dieses Azeotrop siedet bereits bei 71,4°C und 
ermöglicht auf diese Weise eine Abtrennung von Hexame­
thyldisiloxan bei relativ niedrigen Temperaturen von seinen 
Verunreinigungen. Man führt dazu eine oder mehrere 
Schleppdestillationen in Gegenwart von überschüssigem 
Acetonitril durch und trennt das Acetonitril aus der dabei 
anfallenden leichteren Phase wieder destillativ ab. In Erfül­
lung der gestellten Aufgabe wurden neben dem oben 
genannten azeotropen System auch noch ein azeotropes 
System aus Hexamethyldisiloxan und Toluol sowie ein 
weiteres aus Acetonitril und Toluol gefunden. Alle drei 
azeotropen Systeme sind ebenfalls Gegenstand der vorlie­
genden Erfindung.

Abstract: Inlet swirl control means for I.C. engines includes, for 
each inlet port (12, 12′) of an engine, a movable insert sleeve 
(35, 35′) slidingly mounted in the inlet passage (13, 13′) of the 
port as a liner for the passage, the or each insert sleeve

projects to a variable extent into the bowl (14, 14′) of the port. 
The disposition and degree of protrusion of each tongue into 
its associated inlet port bowl controls the degree of swirl 
generated in the associated cylinder. Simultaneous adjust­
ment of the dispositions of the protruding tongues (37, 37′) 
of all the insert sleeves is carried out automatically during 
the running of the engine in response to variations in engine 
operating conditions such as engine speed and load. Such 
adjustment is effected by moving each insert linearly and/or 
rotating it in its associated inlet passage.

Title: Injection molding nozzle probe and stack molding apparatus
IPC: B29C45/32
Filed: 1985-05-20
Abstract: This invention relates to an improved heated nozzle probe for injection molding and an improved stack molding system in which it is used. Each nozzle probe has an inner helical shaped heating element which extends into the pointed tip, and a separate outer one which does not. In addition to providing more heat to the pointed tip, this has the advantage that a standard unit can be used for various applications. In the stack molding system, two heated nozzles are arranged in alignment to bridge the parting line and the pointed tip of only the downstream one is heated. Combined with tapering the aligned gates to gradually increase in diameter in a downstream direction, this has been found to considerably reduce stringing and drooling problems as the mold opens for ejection.
