Abstract: Die Zeit zum Auswechseln von Kassetten (6) in einem 
Extrusionskopf (1) ist möglichst klein zu halten, um den 
Produktionsausfall, der durch den eigentlichen Kassettenwechsel und 
die ggf. eintretenden Folgeerscheinungen bedingt ist, klein zu halten. 
Bisher werden Kassetten (6) u.a. dadurch ausgewechselt, daß sie in 
ihrer eigenen Längserstreckung in einer entsprechenden Ausnehmung im 
Extrusionskopf (1) verschoben werden.  
     Um die Zeit zum Auswechseln 
einer Kassette (6) zu reduzieren, ist eine schwenkbare 
Kassettentrommel (10) mit zwei Ausnehmungen (13, 14) vorgesehen. In 
einer Ausnehmung (14) befindet sich die in Betrieb befindliche 
Kassette (6), während aus der anderen Ausnehmung (13) nach dem 
Verschwenken eine in Betrieb gewesene, alte Kassette (6) entnommen und 
durch eine neue ersetzt werden kann. Durch die Schwenkbarkeit der 
Kassettentrommel (10) können die Kassetten (6) beim Wechsel quer zu 
ihrer Längserstreckung bewegt werden. Die für diesen kurzen Weg 
erforderliche Zeit ist so gering, daß die Extruder in der Regel nicht 
angehalten zu werden brauchen.

Patent EP-0378186-A3 (EP)
IPC: H03K17/082
Filed: 1990-01-10
Abstract: Die Erfindung bezieht sich auf einen AC-Schalter, 
insbesondere AC-Näherungsschalter. Um die bei herkömmlichen 
Schaltern durch die Reihenschaltung eines Thyristors und 
einer Zener-Diode am Ausgang eines an der AC-Quelle 
liegenden Vollwellengleichrichters schlechte 
Schaltpunktstabilität zu verbessern, sind bei der Erfindung 
der Thyristor und die Zener-Diode durch ein MOS-FET (T3) 
ersetzt, der durch eine von einer Eingangsstufe (1,2) 
angesteuerte Steuerstufe (3) angesteuert wird. Die Steuerstufe 
(3) steuert einen weiteren MOS-FET (T4) eines Sourcefolgers (T4,6) 
an, über den bei ausgeschaltetem Gleichrichter (4) die 
Eingangsstufe (1,2) aus der AC-Quelle mit Spannung versorgt wird, 
während beim eingeschalteten Gleichrichter (4) für die 
Spannungsversorgung eine durch den MOS-FET (T3) stabilisierte 
verhältnismäßig kleine Ausgangsspannung des Gleichrichters (4) 
verwendet wird, die wegen des durchgeschalteten MOS-FET (T4) 
praktisch in voller Stärke an der Eingangsstufe (1,2) und der 
Steuerstufe (3) liegt. Wegen der stabilisierten kleinen 
Ausgangsspannung ist die Verlustleistung auch bei 
vergleichsweise großen Strömen klein, weshalb die 
temperaturabhängigen Bodenelemente, die für die 
Schaltpunktstabilität verantwortlich sind, nur 
vernachlässigbar wenig wärmebelastet sind. Mittels eines 
Stromsensors (8), der Steuerstufe (3) und des MOS-FET (T3) ist es 
bei jeder Phasenlage der Spannung der AC-Quelle möglich, im 
Falle eines zu großen Stromes, den Gleichrichter (4) zu 
sperren.

beam (1) during the drilling. The travelling central­
izer (5) of the arrangement comprises two jaw halves 
(12a, 12b) mounted in a carriage (8) provided for the 
travelling centralizer so as to be pivoted about 
journals (13a, 13b) parallel to the feeding beam (1). 
Each jaw half (12a, 12b) comprises a wheel (9a, 9b) 
moving along the guideways (10) of the feeding beam 
(1) and keeping the jaw halves (12, 12b) pressed 
against each other during normal drilling so that 
jaws (14a, 14b) form a drill rod centralizer con­
centric with the drill rod (4). The guideways (10) 
comprise at the forward end of the feeding beam (1) 
a portion (L) which extends downward from the 
straight guideway portion. When the travelling 
centralizer reaches this downwardly extending guide­
way portion, the wheels (9a, 9b) are displaced down­
ward along the surface of the guideways, so that the 
jaw halves (12a, 12b) are pivoted about the journals 
(13a, 13b), thus drawing the jaws (14a, 14b) of the 
travelling centralizer apart from each other so that 
the chuck (3) is able to pass therethrough.

Title: Hydraulic operated impact drilling device, especially for bolt drilling
IPC: B25D9/12
Filed: 1991-08-10
Abstract: Rotary impact drilling devices possess, as main components, an impact mechanism and a rotary mechanism, which can be operated individually or jointly as a function of the working conditions. To prevent unnecessary wear in particular on the impact piston and its sealing elements during purely rotary operation, the use of a stop element (31) is proposed, by means of which the impact piston (3) can be lifted off from the tool-insertion end (12) after the impact mechanism (1) has been switched off. The stop element (31) displaceable in the longitudinal direction of the impact piston is constructed and controlled in such a way that it assumes, as a function of the influenceable pressurisation, either an impact-operating position which is displaced in the direction of the impact-piston tip (3a) and in which the impact piston (3) can act on the tool-insertion end (12), or is displaceable, when subjected merely to a control pressure, in the direction of the return-stroke movement (arrow 21) of the impact piston (3) to such an extent into a rotary-operating position that the impact piston is gripped, carried along and thereby freed from the tool-insertion end (12). <IMAGE>
