Patent EP-0240146-A2 (EP)
Inventor: MUNTER ERNST AUGUST
IPC: H04L7/04
Filed: 1987-02-25
Abstract: The invention provides a method of redundantly encoding 2 n  binary words into 2 m  encoded binary words, wherein m > n, well as circuits for the encoding and decoding of the encoded binary words. The m words exhibit x invariant bits between themselves and the n words and the m - x bits are mapped uniquely to the remaining n - x bits of the binary words. As a result, the encoding and decoding circuits require translation devices of greatly reduced size from what would be expected through conventional design. The encoded data also exhibits all the desirable attributes of edge density and DC balance.

Abstract: Processes and apparatus for treatment of flowing slurries of particulate material mixed in liquid employ a wide, elongated downwardly-slanted, metal tray with upturned edge flanges, cable-suspended for unrestrained vibratory flexing and undulation. The tray is provided with a plurality of ultrasonic transducers mounted on its underside, and the flowing slurry is delivered to the upper tray end, flowing lengthwise down the tray in a shallow flowing sheet. Ultrasonic vibratory energy coupled through the tray to the flowing slurry has a "microscopic scrubbing" action on all particles and agglomerates, breaking the surface tension on the particle, cleaning particle surfaces, and separating different constituent particles and coatings of gels, slimes, algae, clay or mud. Mixtures of fine particles of coal or other valuable minerals with ash, clay, rock or sand particles are separated with unexpected efficiency by these techniques.

Abstract: This invention relates to a smoke generating bomb or shell used for example to break up riots or to provide a screen for troops. The body (13) and tail member (14) of the bomb are constructed out of cross-link plastic material. Incorporated between the smoke composition (30) and the inner wall of the bomb body is an insulating sleeve (35). The cross-linking of the plastic can be achieved by either gamma irridation or by the use of cross-linking additive agents. The use of plastic body and sleeve is likely to reduce the cost of manufacture considerably.

Abstract: Metallic precision attachments/telescopic crowns are usually used as a releasable connection for a combined fixed/removable denture. Metal-based precision attachments must generally be soldered, welded or cast on. The incorporation of the precision attachments necessitates a considerable expenditure in terms of material and time. In the case of a loss of friction, metallic precision attachments/telescopic crowns can only be repaired (if at all) at considerable financial expense. 
<??>In order to provide a denture attachment which is cost-effective and can be used in many ways, spark erosion is used to introduce a groove profile between the telescopic crown and the attached crown of the denture part, into which groove a profile rod made of polyamide is inserted as an elastic friction element. The friction element thus formes a frictionally engaged attachment between the telescopic crown and the crown arranged on this.
