Patent DE-3925663-A1 (DE)
Inventor: KEESEN HEINZ WERNER DR ING
IPC: H04N19/60
Filed: 1989-08-03
Abstract: An apparatus for the transmission and reception of block coded discrete cosine transformed digital video signal having coefficients representing a DC component and a plurality of AC components of various importance. A means responsive to the digital signal separates and stores like components of the transformed digital signal. The like components are assembled into segments which define a portion of a picture. Addresses of the segments are generated and added thereto. The segments are modulated for transmission by a modulating means. Upon reception the modulated segments are demodulated by a demodulating means. The like components of segments are stored responsive to the addresses. A means, coupled to the storing means and responsive to the addresses, reconstructs from the like components, the block coded discrete cosine transformed digital video signal.

Title: Continuously variable arrester for hydraulic cylinder - uses partially hollow piston rod to receive arresting component
Inventor: SZEBOLD JOHANN DIPL ING
IPC: F15B15/26
Filed: 1990-03-15

Abstract: An austenitic structured steel alloy with enhanced abrasion resistance contains the following components (% wt.):C 1.5-2; Mn 8.0-14.0; Si 0.5-1.3; Cr 1.0-3.0; Ti 0.8-2.0; Al 0.3-0.7; B 0.005-0.025; P 0.12 max.; S 0.04 max. and the rest Fe with its usual impurities. The alloy itself (pref. a Mn hardened steel), by virtue of its method of prepn. contains embedded particles of prim. and sec. carbides, and has optimal compsn. (I) of (% wt.) C 1.8, Mn 12, Si 1, Cr 2, Ti 1, Al 0.4, B 0.01, P 0.12 max., S 0.04 max., and the rest Fe. USE/ADVANTAGE - Useful for making armour plate, and also in installations for crushing, hammering, and breaking up metal. Has good toughness and notched bar impact strength. In an example, the additives corresponding to the steel alloy (except Al, Ti, and B) were mixed and melted in an induction oven with a neutral or basic brickwork lining. The Al (either in the form of pure Al or an Fe/Al alloy) was then added to the melt shortly before addn. of the Ti and B, thus minimising the volatilisation loss, and bringing the alloy to the desired compsn.  (I). The alloy was then cast at a temp. of 1500 deg.C. in a casting mould, and specimens of it were soln. annealed, then quenched in water. The finished specimens exhibited increased stability towards erosion and notched bar impact, also a better toughness and hardness.
