Abstract: A metal carrier and a production method thereof for
carrying an exhaust gas cleaning catalyst for automobiles,
autobicycles, and industrial equipment. The metal carrier
includes a metal honeycomb core body pressed into a metal
outer cylinder, and the joined portion of the a flat plate
and a corrugated plate forming the metal honeycomb core body
includes a solder material coated in spots or stripes at
peaks of corrugation of the corrugated plate. The solder
material in the joined portion of the flat plate and the
corrugated plate has a thickness of less than 100µm, the
positions of the joined portions are different between the
surface and backside of the flat plate and corrugated plate,
and the joined portions are present through an unjoined area
having a length of more than 5% of the length of the metal
honeycomb core body from an end face of the metal honeycomb
core body at the exhaust gas inlet side. The joined portion
of the outer periphery of the metal honeycomb core body and
the inner surface of the metal outer cylinder is a plurality
of stripes. The joined portions of the flat plate and the
corrugated plate of the outermost periphery of the metal
honeycomb core body and the metal outer cylinder are not in
line with each other, and the metal honeycomb core body and
the metal outer cylinder are joined intermittently in the 
axial and peripheral directions. In a production method of
the metal carrier, the metal honeycomb core body is pressed
into the metal outer cylinder while the slurry-formed solder
material coated at peaks of the corrugated plate maintains a
fluidity and the solder material coated on the inner wall
surface of the metal outer cylinder has no fluidity.

Title: Druckform für ein Rotations-Hochdruckverfahren
Inventor: OPITZ JOACHIM DR
IPC: B41M1/34
Filed: 1997-10-07
Abstract: Die Erfindung betrifft eine Druckform für ein Rotations-Hochdruckverfahren, bei
der die die Druckfarbe übertragenden Druckpunkte ein Grundraster bilden und von
einer durch Vertiefungen gebildeten Überstruktur überlagert sind. Derartige
Druckformen werden beispielsweise beim Flexodruckverfahren zum Bedrucken von
Glasplatten, beispielsweise Bildschirmen, mit einer Leuchtstoffschicht eingesetzt.
Dabei ist es erforderlich, daß die Druckfarbe einerseits homogon aufgetragen wird
und daß die im Druckbild erscheinenden Farbabdruckpunkte eine gleichmäßige
Randbegrenzung aufweisen. Erfindungsgemäß wird dazu die Druckform derart
ausgestaltet, daß die Überstrukturen relativ zu den Druckpunkten gleichartig
angeordnet sind und, falls die Druckpunkte periodisch über die Druckform verteilt
sind, bevorzugt mit derselben Periode den Druckpunkten überlagert sind. Außerdem
sind die Überstrukturen derart angeordnet, daß die Vertiefungen den Rand eines
Druckpunktes nicht schneiden.

Filed: 1995-04-20
Abstract: A method of grinding crankpins (56) of a crankshaft (54)
wherein the machine is under computer control and the grinding
wheel (40) is advanced and retracted under computer control so
as to follow the planetary motion of the crankpin as the
crankshaft rotates. This maintains grinding contact between
the wheel and the pin to allow the grinding of the latter. The
crankshaft is mounted between centres and is rotated by a drive
unit (52, 46), drive being transmitted to the end of the
crankshaft via a connecting means (10) which is torsionally
rigid in a plane perpendicular to the axis of rotation of the
crankshaft but which is readily deformable in other planes to
accommodate misalignment and so as to decouple the crankshaft
(54) from the drive (52,46) other than to transmit pure
rotation to the crankshaft.
