Patent DE-19819604-A1 (DE)
Title: Dosing plug valve suitable for petrochemical plant
Inventor: HOEBBELMANN FRANZ
IPC: F16K15/02
Filed: 1998-05-02
Abstract: The angle between the conical casing line and the conical axis (24) of the sealing surfaces (13, 14) of the casing (1) and the plug (15) exceeds 10 deg  and is preferably 15 deg -25 deg .  Preferred features: There is a pressure-equalizing channel passing between the space on the large end face of the plug to that at the smaller end face. In the casing there are two flushing channels which can be shut off, discharging into the two spaces. Flushing gas supply passes through these channels. Springs act against the top of the plug to force it and conical seat faces together. The springs are stacked rings, especially star rings. The casing (1) includes a screwed-on outer cover (2) opposite the conical sealing faces. The plug shaft projects through it and has an end face pressing against the springs. The plug is held to the shaft against rotation but has axial movement. The drive shaft (23) includes a bearing (31) supported by the cover. Needle roller bearings and shaft seals are also included.

Patent DE-19829584-A1 (DE)
Inventor: HAHN DIETER
IPC: C21D5/00
Filed: 1998-07-02
Abstract: The invention relates to a method for forming a neck in a cylinder bore to avoid the effects of polishing on an inner cylinder displacement surface made of cast iron and designed for a piston of an internal combustion engine. According to said process, the region of said displacement surface which is occupied by the fire area of the piston upper dead centre is hardened. Said region is hardened so that the cylinder bore has, in this region, a neck resulting from the conversion of austenite into martensite. The neck and hardening on the displacement surface are obtained by inductive hardening of the boundary layer.

Title: Error testing method of RAM especially for mobile radio equipment
Inventor: HERNDL THOMAS
IPC: G11C29/42
Filed: 1998-09-10
Abstract: The method involves sequential and periodic reading of data words from the memory, followed by processing and re-writing into the memory. The data words are provided with parity bits for error/fault tests. A data word (D) is read from an address (3) during a clock-cycle (T) and a parity bit (P) is added to the word. The new data word (D4) is written in to the next higher address in the subsequent clock-cycle (T5), after reading a data word (D5) from the next higher address.  After N clock-cycles, the data word is re-read and has a parity bit added to it. The parity bit is compared with the preceding parity bit of the data word (D4) and a new parity pit (P4N) is added to the new data word (D4N) and then stored. The new, processed data word (D4N) is then written into the next higher address (5), after being read out from the address.
