Title: Method of producing a camshaft arrangement with shaft elements lying one inside the other
Inventor: AMBORN PETER DR ING
IPC: B23K26/28
Filed: 1993-03-03
Abstract: Method of producing a camshaft arrangement for valve-controlled internal combustion engines with two shaft elements lying one inside the other. The shaft elements are mounted one inside the other and can be rotated relative to one another by a limited angle, in which arrangement first cams, designated as inner cams, in particular for the inlet valves are connected to the inner shaft element and second cams, designated as outer cams, in particular for the exhaust valves are connected to the outer shaft element, and the outer shaft has wall openings through which fastening elements of the inner cams pass radially, and at least one of the shaft elements is composed of individual longitudinal sections. In this method, the individual longitudinal sections are made in one piece with at least one allocated cam or are connected to this cam, the cams are finish-machined, hardened and ground before the individual longitudinal sections are put together, and finally the individual longitudinal sections are connected to the completely finished cams. <IMAGE>

Title: Method for producing sensors, and sensor
Inventor: BENZ GERHARD DR
IPC: H01L21/306
Filed: 1993-05-06
Abstract: A method for producing sensors is proposed, the starting point of which is a laminated plate (5) having two monocrystalline silicon layers (1, 2) and an interposed etching layer (3). The upper silicon layer (1) is structured by forming trenches (4). By etching the etching layer (3) under part of the silicon layer (1) thus structured, it is possible to obtain sensor structures, for example a flexural beam (30) which is used in an acceleration sensor (Figure 8).

Patent DE-4336869-A1 (DE)
Title: Method for producing an MOS transistor
Inventor: LEE CHANG JAE
IPC: H01L21/8242
Filed: 1993-10-28
Abstract: A method for producing an MOS transistor is specified, by which all the process steps can be simplified, which increases the yield and the achievable integration density. In order to form a field oxide film, use is made of a Locos insulation technique by using a polysilicon film. A buffer oxide film, as is used for voltage suppression in the production of the field oxide film, and a polysilicon film, which is used for voltage buffering in this step, serve at the same time as gate oxide film or as gate. Accordingly, the steps for producing the field oxide film, the gate insulation film and the gate are not carried out independently of each other, which reduces the number of process steps in comparison with the number in a method in which steps for producing these structures are carried out independently of each other.

Title: Lubricant heating equipment and a lubrication system for internal tooling in tube mills
Inventor: KUEMMERLING ROLF DR ING
IPC: B21B25/04
Filed: 1993-11-24
Abstract: Known lubricant heating equipment and lubrication system, comprising essentially a storage container, nozzle ring, pipelines and filters, are used for lubricating internal tooling in tube mills, esp. continuous tube mills. The novelty is that the heating and lubrication systems are linked so that below a given internal tool temperature, or for a planned tool change, there is an automatic changeover from cold to hot lubricant.  On reaching a given tool temperature, the lubricant in the storage container is held at a base temperature of about 50 deg C and is continuously agitated. The surface temperature of the mandrel bars is ascertained prior to spraying.

Title: Operating method for impact breaker
Inventor: GRONHOLZ CLAUS DIPL ING
IPC: B02C13/09
Filed: 1994-03-17
Abstract: The impact breaker has a motor-driven sledge roller fitted on the circumference with at least two diametrically opposite sledge strips which on the outside are inclined roof-shaped (20a) with the rise running in the rotary direction. At predetermined time intervals the height of the front edge of the strips is measured and the motor speed and gap width, ie distance between impact mechanism and impact circle are adjusted dependent on the height of the profile.  The height and profile of the strips changes with increasing operation, ie the height decreases by an increasing amount. The speed of the motor, starting from a maximum speed value when the strip is new, as well as the gap width (a) are reduced. The extent of the decrease of the speed and gap width is made dependent on the material to be broken. A set of templates is used to determine the height and possible incline of the profile of the strips.

Abstract: Verfahren und Vorrichtung dienen zur Messung einer Wanddickenveränderung, insbesondere einer Wanddickenschwächung (14) auf der Innenfläche (6) eines Rohres (2), von außen her. Dazu wird auf die Innenfläche (6) eine radioaktive Belegung (10), bevorzugt in Form eines Gammastrahlers, aufgebracht. Bei Nuklearkomponenten aus dem Primärkreislauf eines Kernkraftwerkes ist eine solche Belegung (10) ohnehin vorhanden. Zum Auffinden des Ortes (xo) der Wanddickenminderung (14) wird die Strahlungsflußdichte (I) in Abhängigkeit des Ortes (x) entlang des Prüfobjekts (2) gemessen. Sodann wird am besagten Ort (xo) an der Außenfläche (4) die Strahlungsflußdichte (I) in Abhängigkeit von der Energie (E) gemessen; es ergibt sich eine Kurve mit Photopeak (P) und Comptonrücken (C). Schließlich wird eine vorgegebene Relation (V1, V2) zwischen einer charakteristischen Größe des Photopeaks (P) und des Comptonrückens (C) gebildet. Mit Hilfe von Eichkurven (V1*, V2*) kann hieraus auf die Tiefe (t) der Wandminderung (14) geschlossen werden. Auf diese Weise lassen sich nicht nur innen liegende Risse, sondern auch Wandverstärkungen quantitativ erfassen. Ein ähnliches Verfahren läßt sich auch durch Ausmessung der Photopeaks zweier verschiedener Nuklide ausführen.
