Title: Method of manufacturing ball joint between shoe and piston of reciprocating engine
Inventor: HUEHN BERND
IPC: F16C11/06
Filed: 1997-03-26
Abstract: A spherical or cup-shaped recess (2) on piston (1) or shoe (3) is so undercut as to give a cup over more than 180 degrees angle and a diameter (D) at equator line greater than the open diameter of the recess (2). A ball head (11) is moulded on shoe or piston as appropriate and pressed into the recess (2) so that recess rim area (6) is elastically deformed during this and grasps round the inserted ball head. When this is pressed in, the tension is evenly distributed in round the cup rim area (6). The expansion of the rim at this stage is supported by a fluid or gaseous medium (15) fed via a bore (7) in piston or shoe to the cup recess and pressurised (p). The rim of the recess can be radially slotted out to assist in its elastic deformation. The ball head is preshaped to give a flat on both sides and the exterior of the head is adapted to the internal surface of the recess cup.

Patent DE-19750300-A1 (DE)
Inventor: BORG SOEREN
IPC: F16K1/44
Filed: 1997-11-13
Abstract: The invention relates to a double seat valve with leak protection. A common drive mechanism is provided for operating both valve discs (6, 7). Said drive mechanism contains a cylinder (17) with a first working piston (18) which is subjected to the action of pressure springs (29, 22) at both ends and which is rigidly connected to the valve stem of the lower valve disc (7). Said valve stem (13) passes through the upper valve disc (6) and its tubular stem (14) telescopically and the top end of the shaft projects into the cylinder (17) where it supports an abutment (28) for the lower pressure spring (29) which pushes the upper valve disc (6) into its seat (8). A second working piston (36) which moves on and acts upon the tubular shaft is located in the cylinder (17) below the first working piston (18) and a third working piston (30) which acts on the lower valve disc is located above the first working piston. The invention provides that the first spring (22) is positioned so that it rests on the third piston (30). As a result, the drive mechanism consumes less air and the valve switches more rapidly.

At least one movable and at least one rigid cam element are assigned to the same catch.
Patent DE-19755192-A1 (DE)
Title: Capacitive pressure pickup for measuring pressure in IC engine combustion chamber
Inventor: LOEHR WIKHART
IPC: G01L9/00
Filed: 1997-12-12
Abstract: The sensor is encapsulated by a protective diaphragm (1). The combustion chamber pressure is transferred from the diaphragm as a force on a transfer plunger (2), for thermal decoupling. A lifting element is moved by the plunger, and its displacement alters the capacitance of a capacitor. The material of the measuring capacitor is chosen to match heat expansion coefficients, so that temperature changes produce insignificant capacitance changes.

Title: Method and apparatus for relating two coordinate systems for purposes of wear measurement on the lining of a metallurgical vessel
Inventor: KIRCHHOFF STEFAN
IPC: F27D21/00
Filed: 1998-03-02
Abstract: Measurement of the lining is carried out at specific reference points on the lining of a metallurgical vessel. Before the metallurgical vessel (20) is used, the position of at least three reference points (P1, ..., P4, ...) is determined to establish an object coordinate system for the vessel, and measurements on the vessel lining by a system (10) with use of electromagnetic radiation are carried out. After use of the vessel the positions of the reference points are determined by comparison of the position of the object coordinate system relative to the coordinate system of the measuring system (10). This in done by projection of the reference points onto the plane of an optical identification unit (8). Afterwards determination of the coordinates of the reference points and measurements on the vessel lining are carried out automatically by the measuring system (10). The apparatus includes at least one optical identificaton unit (8), as well as means by which the sender/receiver unit (1) is automatically directed to the reference points.
