Title: Hydrodynamic axial thrust bearing - has adjustable spring loaded bearing pads located by spherical seats
Inventor: NEUMEYER HANS-JOACHIM
IPC: F16C17/06
Filed: 1977-01-17
Abstract: A hydrodynamic axial thrust bearing has a flanged base ring (12) which carries a number of equally spaced convex location pads (40). Each pad locates a concave spacer ring (42) such that the curved faces are in contact. The outside face of the spacer ring is flat, and placed on it is a bearing pad (32) which has a convex location face. A spring loaded coupling pin assembly (22) is used to maintain an adjustable bearing pad location. Due to some radial freedom of the bearing pad (32), each bearing face (16) is able to find its correct axial position when the bearing is under load.

Title: Automatic start=up of flame cutting operations - where change of electrical resistance of flame indicates its contact with workpiece
Inventor: PUSCHNER PETER DR ING
IPC: B23K7/10
Filed: 1977-06-02
Abstract: A gas burner is automatically guided along a path to find the edge of a workpiece which is to be cut by the flame. The resistance of the flame between the burner and the workpiece is monitored in an electric or electronic circuit, and the change in resistance which occurs when the flame impinges on the workpiece is used for automatic starting of the preheating phase and the cutting phase. Cutting O2 is ref. fed through the burner as it is moved towards the workpiece, and the cutting O2 is switched off when the burner is over the piece and the preheating phase commences. Several burners may be actuated in this manner in a time-multiplex cycle. The resistance of the flame is pref. measured in an a.c. circuit at a defined frequency using a tuned filter.

Title: Liq. chromatography eluant changing system - uses neutral gas as flushing medium
Inventor: HUBER J F K PROF DR
IPC: G01N30/38
Filed: 1977-09-26
Abstract: Method for changing the eluant in the on-line operation of a liq. chromatography column uses, after the column has been cut off from the first eluant, a gas which is neutral relative to the eluant and to the sample material. The gas is passed at a raised temp. through the column until the first eluant has been displaced or evaporated. The column is then switched over to the second eluant. The eluant can be changed on line without having to take sample components from the chromatograph and having to treat them in a separate analytic operation.

Title: Marking tool for plastics labels - has spring adjustment of axial force to prevent damage to cutting tool
Inventor: MUELLER MANFRED
IPC: B44B3/06
Filed: 1977-11-26
Abstract: A tool for marking letters or numbers on plastic labels which are attached to hard surfaces has a cylindrical body (1) with a motor (4) driving a chuck (14) which holds the marking tool or stylus. A spring (16) between the bearings (9) (11) controls the axial force exerted on the marking tool. This axial force can be adjusted by a knob (18) attached to a pin sliding in a helical slot (19) which moves the housing (10) of the upper bearing (11) downwards and compresses the spring (16). The axial force is adjusted so that the tool just penetrates the plastic label and is not damaged by the hard under-surface.

Title: Isolator for spherical fuel elements - has duplicated turnstiles with spheres blown across by helium when blockage occurs
Inventor: LOIMANN EUGEN ING GRAD
IPC: G21C19/20
Filed: 1978-12-22
Abstract: Each of the pair of devices permitting the passage one by one of spherical fuel elements in an arrangement for singling out the spheres so that they can be counted, in spected, etc., has >=1 means by which a blast of gas can be directed across and near enough parallel to the surface of one device towards the second device of the pair. Used in the fission zone of a stacked ball reactor which may contain three million spherical fuel elements, which are cooled by a stream of gas through the stack; fresh balls being introduced at the top, whilst used balls are extracted from the bottom. Invention provides an escapement mechanism through which the balls pass one behind the other, and in which, in the event of breakdown no balls remain in front of the damaged mechanism, since they are removed by the device which remains intact. The He gas already available for cooling is used and a stream of gas at 47 m/s enables a sphere 60mm in diameter and weighing 200g to clear an obstacle 10mm high.
