Title: Trusted message transmission method involves transmission based on symmetrical encoding algorithm with key management center decoding and re-encoding message using key database
Inventor: BENZLER HARTWIG
IPC: H04L9/32
Filed: 1999-05-22
Abstract: The method involves transmission based on a symmetrical encoding algorithm, whereby the sender (A) provides his message (N) with an identifier (KE) and encodes them together or separately with a key to form a crypto message and transmits the crypto message with his own identifier (SA) to the key management center (SVZ). The center decodes the message by obtaining the key from a database, encrypts the message after providing the sender's identifier, then sends the encrypted message plus the original identifier to the receiver (E), which decrypts it using its key (SE).

Abstract: The method involves storing sub-images preceding the current sub-image of a sequence and forming a first complementary sub-image by comparing image point signals in the current and stored sub-images. A second complementary sub-image is formed by forming a mean value of two pixel signals of the pixel vertically adjacent to a pixel in the current image. A pixel of the first or second complementary sub-images is selected depending on spatial and temporal modification of the pixel signals and vertically adjacent pixels.  An Independent claim is also included for an arrangement for doubling the image repetition rate of an image sequence generated with the line jump technique.

Patent DE-19936566-A1 (DE)
Inventor: JUENGLING STEPHAN
IPC: C08C19/44
Filed: 1999-08-04
Abstract: Disclosed is a method for the production of a solution of high molecular polymers of conjugated dienes in a vinyl aromatic hydrocarbon by anionic polymerisation of said diene in the presence of an alkyl lithium catalyst. The invention also relates to a method for the production of resistant polymers of vinyl aromatic compounds. The process consists of initially polymerizing the diene in an aromatic solution consisting of a hydrocarbon which is devoid of any ethylene double bonds, until a molar mass of less than 10<5> is obtained. Thereafter, trialkyl aluminium with a higher molar mass than the alkyl lithium is added. The solution thus obtained is then diluted with a vinyl aromatic compound; thereafter, the polydiene is coupled to a polyepoxide or an alkyl(meth)acrylate to form a higher molecular polymer. The resulting solution is further treated to form a resistant polymer of a vinyl aromatic hydrocarbon, whereby the solution produced according to the above-mentioned process is polymerised in a known manner per se, optionally after further amounts of a vinyl aromatic compound are added.

Title: Hydraulic equipment driving closure mechanism of pressure injection mold, includes displacement control valve with spool configured for both control and braking functions
Inventor: DANTLGRABER JOERG
IPC: F15B13/043
Filed: 1999-10-22
Abstract: Hydraulic valve (20) controlling mold displacement is controlled in turn by precontroller-valve (55) connected to two pressure chambers (52, 53). Either can be pressurized from supply line (13), whilst the pressure in other is reduced. Throttling effect is produced on through flow, which depends only upon position of control piston ( spool in the hydraulic valve 20) relative to neutral position. Preferred features: Load (31) displacement is measured by a transducer (32). The hydraulic pump (10) throughput can be controlled in accordance with a predetermined load displacement/velocity diagram. Cross section available for flow in the control valve (20), between the feed- (P) and consumer- (A, B) connections is determined by sharp, orthogonal edges (43, 44) of the control spool (40). Outlet control edges (45, 46) are e.g. chamfered. For a given displacement from the neutral position, with opposite flow directions, the cross section available is greater between one consumer connection (A) and the corresponding outlet (T) than between the other consumer connection (B) and the corresponding (common) outlet (T). The hydraulic closure cylinder (25) is double-acting, the larger chamber (3) being the working, closure side, with similar provisions concerning the edges and throttling effect of the controlling spool valve (20). A corresponding 4/3 way valve is also claimed.
