Patent DE-4305669-A1 (DE)
Title: Elliptical rotary internal combustion engine
Inventor: HUA MIAO
IPC: F02B55/00
Filed: 1993-02-24
Abstract: How can the air resonance pressure, generated by the combustion be fully converted to a drive force, the internal combustion engine's own mechanical power consumption be reduced and the structure of the internal combustion engine still be of simple and compact design? The elliptical rotary combustion engine solves such problems by means of the invented structure, because it has the advantages of lower fuel consumption, greater capacity, lower exhaust noise, reduced inherent mechanical power consumption, shorter acceleration time, more even and quieter rotation and less vibration. In the structure of the elliptical rotary internal combustion engine the VA chamber (Fig. 2) is divided and larger than the AK chamber (Fig. 2) by a suitable ratio. In this way the air resonance pressure generated by the combustion in the VA chamber (Fig. 2) can drive the VA rotation (No. 5 of Fig. 1, Fig. 16 to 18) until it is equal to the external air pressure, for which reason this engine can fully convert such pressure into drive force. The VA rotation (No. 5 of Fig. 1, Fig. 16 to 18) is driven by the air resonance in each direction at an angle of approximately 300 DEG , so that this engine can prolong the period of its working stroke in relation to the period of its rotation. The elliptical rotary internal combustion engine uses five simple combined systems making it simpler and more compact. <IMAGE>

Title: Device for the digital shape control of profiles
Inventor: ROESEL OLAF
IPC: G01B5/20
Filed: 1993-04-27
Abstract: The traditional shape control of ships' frames, deck beams etc. is carried out using templates which are often prepared in accordance with loft lines. The production of control templates is very costly. A further disadvantage is that only the accuracy of the shape can be checked using the control templates. It is further known that profiles are shaped using the method of the inverted line. The disadvantage of this method is that longitudinal and transverse shrinkage influence the dimensional accuracy of the degree of shaping. The invention seeks to provide a remedy. The invention is based on the problem of providing a device for the digital control of shaped profiles, in particular of ships' frames, deck beams, etc. which makes possible the control of their accuracy as regards shape and their dimensional stability by measuring the profile contour at the moulding edge at arbitrarily freely selectable distances. The measurement itself is controlled using a computer (eg. a PC) and is evaluated in a manner suitable for the data by means of specially prepared software. In order to enable mechanised quality control in the production of ship parts, a pick-up table and a measuring table are arranged on the moulding edge of the shaped profile at freely selectable locations, each table having a wind-up device for accommodating a measuring wire and measuring and guide rollers and clamping elements and a traveller having measuring rolls arranged above and lateral sliding and guide rollers is used in such a manner that it ...
