Patent DE-19712186-A1 (DE)
Title: Control device for fuel metering of internal combustion engine
Inventor: THIEME MICHAEL
IPC: F02D41/22
Filed: 1997-03-22
Abstract: The control device (10-21) meters fuel for an internal combustion engine, using signals like speed and load signals. It evaluates the speed run-up during the start and corrects the fuel metering according to the evaluation of the speed run-up. Correction possibilities for individual cylinders are provided for the injection signals in the starting case. The respective injection signal for each individual cylinder during starting is determined in dependence upon the switch-off time and a physical model for the treatment of leakage quantities. The switch-off time is measured, or approximated to, from the difference of engine temperature between the switch-off time and the new-start time.

Title: Head positioning error compensation in hard disk drive
Inventor: JEON DO-YOUNG
IPC: G11B19/04
Filed: 1997-04-15
Abstract: The method involves controlling a hard disk drive which includes a digital signal processor programmed with a feedback control algorithm and a repetition control algorithm.  The method includes the step of preserving the data of position error signals according to the sectors which are recorded along a certain track, in a track following mode.  The PES data are sequentially stored in a table. The correction values for a repeating follow-up error are determined through processing of the PES data for the corresponding sector, and the PES data for the preceding and the following sectors.  These are read from the table, and through the feedback control algorithm and the repetition control algorithm in the next, following period of the corresponding track.

Title: System recovering excess energy radiated by electrodeless light sources excited by microwaves
Inventor: STOBBE RALF
IPC: H01L31/0445
Filed: 1997-04-18
Abstract: This system recovers energy radiated from electrodeless light sources, especially rotating, cooled spherical lamps containing small quantities of argon and sulphur or selenium. These are subjected to the electromagnetic fields of micrometric waves, focused by a wire cage. Glaring, cold and resembling sunlight spectrally, the  light enters a lengthy light tube with internal, partially-reflective layer. This directs the light through apertures onto the surface to be illuminated. The light tube is surrounded by a second coaxial tube. Plastic screens occupy the interspace. In this new development, on their curved surfaces (10) a photovoltaic layer (12) converts transmitted light into direct current. Alternatively, the light tube (1) is at least partially surrounded by a casing (14) substituting for the screens. This is similarly coated, and has light outlet apertures.

Title: Recovery of hydrofluoric acid and nitric acid from air vented from metal pickling plants
Inventor: ROESCH GERHARD
IPC: B01D53/56
Filed: 1998-02-21
Abstract: In a first stage hydrofluoric acid (HF) is removed from air by washing first with dilute HF solution and then with clean water. In a second stage, nitrogen oxide (NOx) is removed by treatment with an aqueous solution of nitric acid (HNO3) and hydrogen peroxide (H2O2). In the first washing in dilute HF, the dwell time of the air stream in the active zone is ca. 2.5 seconds. When washing with water the dwell time is ca. 1.5 seconds. The H2O2 is added to the liquid in the NOx washer immediately before the HNO3 enters the packed column. The amount added is about 1.8 times the stoichiometric requirement. The mean dwell time of the H2O2 in the absorption zone of the NOx washer is a maximum of 120 seconds.
