Patent EP-0008388-A3 (EP)
IPC: C04B2/10
Filed: 1979-07-30
Abstract: Bei thermischen Prozessen, insbesondere beim Brennen 
oder Sintern von Kalk, Dolomit oder Magnesit ist es zur Erzie­
lung guter Wirkungsgrade häufig notwendig, die Heißgase 
mit Hilfe thermisch hochbelastbarer Fördervorrichtungen. z. 
B. Gebläse oder Gebläsemühlen, an bestimmten Stellen der 
Öfen oder anderen Einrichtungen zum thermischen Behan­
deln der Güter abzuziehen und an anderen Stellen wieder 
zurückzuführen.  
     Damit die Fördervorrichtung auch bei Temperaturen zwi­
schen 600° und 1300°C und hohen Druckverhältnissen stabil 
arbeitet und dabei frei von Ablagerungen des geförderten 
Gutes oder der Stäube bleibt, ist die Fördervorrichtung als 
mechanische Vorrichtung ausgebildet und wird zumindest 
teilweise durch eine Kühlflüssigkeit, insbesondere ein Wär­
meträgeröl, das in einem geschlossenen Kühlkreislauf 
umläuft, gekühlt.

Filed: 1981-12-23
Abstract: Bei der Herstellung hydraulischer Teleskopzylinder wer­
den die einzelnen Rohre von vorgefertigten, kaltgezogenen, 
innen gehonten und außen rundgeschliffenen Stahlrohren 
abgeschnitten. Die Rohrstücke erhalten darauf an einem 
Ende einen äußeren Ring (17) und am anderen Ende einen 
inneren Ring (16). Diese Ringe sollen verhindern, daß die 
Rohrstücke im fertigen Teleskopzylinder auseinander gezo­
gen werden, und werden derart befestigt, daß die erforderli­
che Erwärmung so gering ist, daß die Rohre nicht deformiert 
werden, z.B. durch Kleben oder Hartlöten, und daß keine 
Nachbehandlung der Stahlrohre nötig ist. Wenn vorgefertig­
te Ringe mit Ausdrehungen für Schließ-, Abstreif- und 
Dichtungsringe verwendet werden, können die Rohrstücke 
unmittelbar nach dem Befestigen der Ringe zu einem 
Teleskopzylinder zusammengefügt werden. Gegenüber her­
kömmlichen Herstellungsverfahren ist dieses Verfahren wirt­
schaftlicher bezüglich Arbeitszeit und Materialien, und es 
erfordert keine Sondermaschinen.

Title: Apparatus for heating stacked dishes
IPC: A47J39/02
Filed: 1983-06-30
Abstract: The present invention relates to an apparatus for heating stackable dishes. The apparatus includes a shaft-like heatable housing with an open top which can be closed off with a cover. A support for a stack of dishes is disposed within the interior of the housing. The support moves translationally in the vertical direction on guide rails and is linked to endless chains which are driven by an electric motor. By operating the electric motor, the support with the stack of dishes is moved to a vertical position which is convenient for removing or inserting dishes. This movement may be executed following an automatic opening of the cover. The operator does not need to bend over or to stretch to reach the dishes. An automatic control further serves to lower the stack of dishes into the housing and to close the cover after the passage of a predetermined time interval at the desired vertical position.

Filed: 1983-03-31
Abstract: Apparatus for automatically or remotely dividing a two 
pump unit hydraulic steering system, upon detection of 
dangerous loss of fluid, into two independent steering 
systems in order to maintain steering capacity utilises an 
isolation valve (10) for blocking interconnecting piping (11, 
12) in conjunction with by-pass valves (15, 16) for relieving 
resistance by one ram group (24) to motion of another (25). 
The valves (15, 16) and the pump units (13, 14) are regulated 
automatically or remotely by a control unit (21) in response 
to detection of fluid loss to achieve steering by the ram group 
on the loss-free side.

IPC: G07C1/14
Filed: 1983-08-25
Abstract: There is disclosed herein an improved card reader for a 
security system utilizing a central controller and a plurality of 
card readers for controlling traffic through critical doors in a fa­
cility. The improved reader includes means for improving the 
system throughput by buffer storing large numbers of transac­
tions all occurring within a short time for time clock functions in 
time and attendance applications for hourly employees. Also 
disclosed are means for conditioned emergency responses to 
sensed changes in status of alarm contacts coupled to the 
reader and located in the vicinity of the reader within 2 miles. 
There is also disclosed means for temporarily storing transac­
tion information for transactions made during periods when 
communications with the controller are lost. During such de­
graded mode operation, access is granted to cardholders with 
the proper system code and their ID code and the time of the 
transaction are stored in a buffer. When communications are 
restored, the transactions saved in the buffer are sent to the 
controller.

Patent EP-0131429-A3 (EP)
IPC: B21D9/05
Filed: 1984-07-04
Abstract: Apparatus for draw-bending metal tubes and other elon­
gated workpieces of hollow section, in which a mandrel, sup­
ported on a bar within the tube, bears against the inner wall of 
the tube in the region of the bend and helps to prevent the 
tube section from collapsing or distorting. Vibration trans­
ducers (26) are attached to the bar to set up a standing wave of 
resonant vibration within the mandrel (19) and bar (14) which 
has the effect of reducing friction between the mandrel and 
the tube. A special coupling device (25) may be used to attach 
the transducers to the bar and may also serve to connect the 
bar to the fixed structure of the apparatus, and the invention 
includes the complete apparatus when tuned so as to gener­
ate a displacement antinode of vibration at the mandrel tip, a 
displacement node at the point of attachment of the coupling 
device to the structure, and agenerally so as to minimise 
waste of the vibratory energy.

Title: Method and apparatus for controlling ink-jet color printing heads
IPC: B41J2/01
Filed: 1985-07-12
Abstract: Method and apparatus are provided for controlling a group of ink-jet printing heads to selectively apply (or not apply) dots of one color and of substantially fixed size in random dot pattern arrangements to dot positions of a plurality of pixel areas located sequentially along a line scanned by the printing heads. A sequential series of F integral value color image density signals representative of the tone value at which a respective one of the pixel areas is to be printed by the colored dots is produced. A number of different dot pattern arrangements are listed in a table for the F integral values to produce the tone value representative of a density signal of such an integral value. One of the dot pattern arrangements is randomly selected whenever a color density signal of the integral value appears. The group of ink-jet heads apply colored dots onto the dot positions of the associated pixel area in accordance with the pattern randomly selected.

Abstract: A chair of the swivel and tilting type includes a seat (11) 
and back (12) supported on a pedestal with the seat and back 
being pivotal both rearwardly and forwardiy from a neutral 
position in which the seat is substantially horizontal. The 
principal pivot position (75, 76) for the seat in its relationship 
to the back is located on each side of the seat at substantially 
the ideal natural body pivot of the user which is somewhat 
above the seat and forward of the back. The back pivot (50) 
is located in the base (10) at the top of the pedestal and es­
sentially vertically below such seat pivot, the link (58) sup­
porting the back also supporting such seat pivotal support. 
The seat pivotal support may be rocked with the back sup­
porting link fore and aft the neutral position. An L-shape seat 
cradle (78, 81, 88) is pivotaliy suspended from the pivotal 
support and forms one link of a four-bar linkage, the opposite 
end of the seat cradle being pivoted to a front link (92), in turn 
pivoted to a fixed link (10) or such base, as is the link (58) 
supporting the back. A pair of opposed springs (40, 41) hold 
the chair in the neutral position and readily return the chair 
to that position. The described four-bar linkage provides a 
rearward seat/back tilt ratio of about 1 to 3, and a more li­
mited forward seat/back tilt ratio of approximately 1 to 2, 
respectively. The entire seat and back may be vertically 
adjusted, the back may be adjusted vertically with respect to 
the seat, and a spring loaded shoulder support (120) may be 
provided. The seat on its supporting link or cradle may be 
adjusted fore and aft to adjust seat depth. In addition, remov­
able, height adjustable arm rests (17, 18) may be provided 
mounted on the pivotal supports, such arm rest being side-­
to-side interchangeable to widen or narrow the distance 
therebetween.
