Title: Method of operating I.C. engine
Inventor: SPEIL WALTER DIPL-ING
IPC: F01L1/24
Filed: 1994-04-29
Abstract: The control cam actuates the gas valve (5) by a cam follower (2) which is formed as a rocker arm or drag lever. The cam follower acts on the valve by a lever-end and is supported on a cylinder head (4) by a support which contains a hydraulic play compensator (9).The cam follower has two operating positions in relation to a stroke-cycle of the control cam (8) during the engine operation.

Patent DE-4430814-A1 (DE)
Title: Method for controlling a digital copier and digital copier for a two-side document-copying mode
Inventor: OHTANI MASAYUKI
IPC: G03G15/36
Filed: 1994-08-30
Abstract: In a digital copier which can be operated using a two-side document-copying mode, when an automatic document feed unit (ADF) is used, a second side of this document is read when the two-side document-copying mode is selected and the resulting image data are written into a storage device which can accommodate image data which represent two documents. A first side of the document is then read and stored while, at the same time, the image data which represent the second side, are read out and printed by means of a printer. Then, image data which represent the first side are read out and printed. In consequence, the document can be replaced before the previous side has been copied completely. As a result, an additional time period which is otherwise used for replacing documents is no longer needed. The overall time in which a copier is occupied can thereby be reduced as a result, this giving rise to an efficient operation of the copier. One of two different types of interruption devices is furthermore freely selectable, so that scanner and printer can be used independently of each other based on the interruption mode.

Abstract: Le but de l'invention est de réaliser un télescope à réflecteur composé d'un tube (2) agencé à l'intérieur d'un logement sphérique (1) et d'une calotte de support (4) dans laquelle est monté le logement sphérique (1). Dans un télescope à réflecteur connu, le tube peut être mis en rotation autour de son axe polaire et de son axe de déclinaison, ce qui requiert deux systèmes différents d'entraînement. En outre, l'accès au logement sphérique se modifie selon la position de celui-ci. Afin d'éviter ces inconvénients, le logement sphérique (1) est rotativement monté autour d'un axe horizontal (8) à l'intérieur de la calotte de support (4) et celle-ci est rotativement montée autour d'un axe vertical (50) dans une charpente de base (5), ce qui assure un accès stationnaire continu au logement sphérique (1), donc au tube (2). En outre, l'entraînement du logement sphérique (1) peut être très facilement construit.

Title: Process and device for operating a gas turbine with introduction of additives
Inventor: CZECH NORBERT
IPC: C10L10/00
Filed: 1989-01-19
Abstract: In a process involving at least one burner in a combustion chamber, damage to the components of the gas turbine due to the presence of vanadium in the fuel is prevented by spraying an aqueous solution of a magnesium compound separately into the combustion chamber. A device for carrying out the process consists of a burner (1) known per se with devices for spraying water (2) or steam (3). Said device communicates with a reservoir (4) through a dosing device (5). The invention replaces the use of expensive, oil-soluble magnesium compounds by the simpler, more economical use of water-soluble magnesium salts.
