Patent DE-3407010-A1 (DE)
Title: Body of hardened, metastable cast iron and process for the preparation thereof
Inventor: WIZEMANN KURT
IPC: C21D5/04
Filed: 1984-02-27
Abstract: A body of hardened, metastable cast iron having an at least partially martensite-type microstructure, which contains graphite segregations and which is nitrided in an outer volume region extending from one surface into the body, is to be improved in such a way that said body is highly stable to sliding and rolling and at the same time is highly resistant to wear due to adhesion and abrasion. To this end it is proposed that the outer volume region, with the exception of finely dispersed globular graphite segregations, be essentially free of graphite. Moreover, a process for preparing such a body is proposed, by which the outer volume region can be obtained by nitriding prior to hardening by heat treatment of the cast iron.

Patent DE-3426044-A1 (DE)
Title: Running wheel for vehicles of all kinds
Inventor: ABRAHAM SIEGFRIED
IPC: B60B19/00
Filed: 1984-07-14
Abstract: Rapid heavy vehicles stress the carriageway often a thousand times more than passenger cars. The problem can be reduced with wide tyres, double tyres and double axles, but not resolved. Track-laying vehicles are also out of the question because they are of a very complex design and are costly to maintain and do not permit high speeds. Above all, the invention is to provide an inexpensive, rapid running wheel with a large contact surface of the tyre. For this purpose, the concept of the running wheel which is reduced to a running and guide ring is adopted. However, all the constructional measures which are intended to keep the guide ring in an approximately circular shape during travel are dispensed with here. The flattening on the carriageway is desired and is even constructionally promoted in diverse ways. This takes place for example by means of a flat support of the guide ring on the body of the vehicle or separation and insertion of horizontal elements into the guide ring.

Title: Device for the flat lapping or surface grinding of workpieces
Inventor: BRUGGER RUDOLF DIPL ING
IPC: B24B37/10
Filed: 1984-09-07
Abstract: In order to achieve high degrees of accuracy in terms of dimension and shape in flat lapping or surface grinding, the abrasive carrier (St) is arranged displaceably on the sliding plane (Ge) of a level sheet-like joint and is coupled to a gear mechanism (G, G'), the driven member of which describes an epicycloid or hypocycloid. Two gear mechanisms (G, G') arranged at a distance from each other are preferably used, their driven members describing shortened hypocycloids. The driven members are coupled to the abrasive carrier (St) by means of coupling members (Ku, Ku') which are preferably formed as leaf springs. Exact guiding of the abrasive carrier (St) on the sliding plane (Ge) is preferably ensured by a magnetically provided initial stressing force. The device according to the invention is suitable, in particular, for the precision machining of the end faces of optical waveguides. <IMAGE>

Title: Hydraulic working cylinder
Inventor: ERSOY METIN DR ING
IPC: F15B15/14
Filed: 1984-12-22
Abstract: The invention relates to a hydraulic working cylinder, in particular for scissor systems in scissor-type lifting tables and the like. Despite all endeavours, it is unavoidable that the piston rod and piston will tilt in the cylinder sleeve during extension of the piston. The guide for the piston rod in the cylinder sleeve is damaged and worn after a relatively short time. In order to avoid this, it is proposed according to the invention that the piston have a guide for guiding the piston in the cylinder sleeve, that the piston rod run in the cylinder cover in a seal, and that a further guide for guiding the piston rod in the cylinder sleeve be arranged below the cylinder cover.

Title: Doppler log for a vehicle, particularly a watercraft
Inventor: STEFFENS HANS DIPL ING
IPC: G01S15/60
Filed: 1984-12-24
Abstract: For the purpose of accurate determination of the velocity component (vH, vL) in the horizontal and vertical direction independently of the velocity of sound, this Doppler log exhibits a transmitting and receiving device (12) for sending out wave energy and for receiving the reflected wave energy from two selective directions of reception (A, V), inclined to the transducer plane (14) and located symmetrically with respect to the normal of the transducer plane (14), and from a third selective direction of reception (O) coinciding with the normal. The directions of reception (A, O, V) are adjusted by suitably shifting the phase ( phi ) of the received signals of the individual transducers (15). The Doppler frequency (fA, fO, fV) is determined from each direction of reception (A, O, V). From the Doppler frequencies (fA, fV) of the inclined symmetrical directions of reception, the Doppler difference ( DELTA f) which is a measure of the velocity along the longitudinal axis (16) of the vehicle is determined, on the one hand, and, on the other hand, the Doppler sum ( SIGMA f) is determined. A processor (27) calculates from the Doppler sum ( SIGMA f) and the Doppler frequency (fO) from the third direction of reception (O) a velocity term (T) which is logically combined with the Doppler difference ( DELTA f) and the elevation angle ( epsilon ) for determining the accurate horizontal and vertical components (vH, vL) of the vehicle velocity. <IMAGE>

Title: Method for the production of, in particular, thick-walled tubes
Inventor: MARTIN OSWALD DIPL ING
IPC: B23K33/00
Filed: 1985-02-28
Abstract: To improve the quality of the weld seam and to save on welding consumables, a method for the production of, in particular, thick-walled tubes which are bent round from a sheet-plate blank and welded together with a longitudinal weld on the inside and the outside is designed in such a way that, first of all, only the chamfers for the relatively small inner weld seam are formed at the longitudinal edges of the flat sheet-plate blank and then the longitudinal edges of the sheet-plate blank are bent slightly in a known manner, whereupon the sheet-plate blank can be bent round in a known manner on a three-roll bending machine. The longitudinal edges are then tacked on the outside at the butt joint, whereupon the inner weld seam is produced. In the following method step, the welded joint of the outer weld seam is milled out to the root of the inner weld seam in a process involving removal of the tack welds and the outer weld seam is then produced, the compression zones formed during the initial bending of the sheet-plate blank being largely eliminated by the milling out of the seam. It is advantageous to employ an outer weld seam with a bell-shaped cross-section although a V seam is also possible.
