Title: Centrifuge bowl with improved abrasion resistance - having grid formed from wedge-shaped bars with transverse and vertical mounting in conical bowl
Inventor: ASNER VLADIMIR ILITSCH
IPC: B04B7/18
Filed: 1977-07-07
Abstract: Centrifuge bowl for a sieve type centrifuge has a conical shape. It is constructed from segments each of which is in the form of a grid formed from a series of rods with wedge or trapezium shaped cross section. The narrow aperture between adjoining rods is mounted on the inner surface of the bowl and this serves to support the filtered material. The edges of the segments on both sides have reinforcement ribs mounted along the conical profile at the stress points of the segments. These ribs consist of a protective plate which in the longitudinal direction extends over the complete impact length of the segment on the inside of the bowl and which overlap the adjoining segments. Used in sepg. materials esp. abrasive ones such as coal and sand. The construction of the connection joints of the centrifuge ensures that premature failure of the weld connections and reinforcement ribs does not occur.

Title: Splitting glass blocks into two plates by thermal stresses - where block is first cooled and then heated so it cracks along score mark
Inventor: STAHN DIETER DIPL PHYS
IPC: C03B33/095
Filed: 1978-03-28
Abstract: A score mark or groove is made on the periphery of the block and between its two end surfaces to produce a zone of weakness. Cooling (a) is then used to create thermal stresses in the scored block, so the latter cracks along the score mark leaving only a small uncracked zone, heating (b) on the block is next used to complete the crack, thus forming two glass plates. Cooling (a) is pref. achieved by immersing the block in a bath of coolant, then allowing the block to return to room temp. in ambient air, or immersing the cold block in a water bath (b) at or above room temp. A clamp is pref used to apply compressive stress at the top corner of the block while the opposite corner is immersed in bath (a); the clamp is removed after cooling (a) and before heating (b). Used e.g. in mfg. optical components, where no expensive tools are needed to cut the block.

Title: Bend resistant crane type girder - has initial pressure stressing in pressure chord area subjected to external load
Inventor: SCHMIDT KARL PROF DR ING
IPC: E04C3/04
Filed: 1978-06-21
Abstract: The flexural stress girder, esp. in crane girder form, is prestressed by elements generating flexural tension in the girder, and pressure tension in the longitudinal direction in a prestressed area. Pressure prestressing is used in the area subjected to pressure under the effect of an external load. It can have an initial curvature opposing the load-imposed bending line (4), being at least partially restored to a straight configuration by its prestressing. This is distinguished by high bend resistance, with insensitivity to oscillation.
