Inventor: VIESSMANN HANS DR
IPC: F24H9/00
Filed: 1991-07-13
Abstract: The flat heating gas draught tube is intended in particular for useful heat heating boilers of small capacity with atmospheric or gas blower burners and consists of two parallel and fluid-tight  metal wall sheets (4) which are interconnected along two opposite edges and delimit the water-bearing inner space except for inflow and outflow openings and which are provided with undulating parallel shapes. According to the invention, such a flat heating gas draught tube is designed in such a manner that the shapes are formed out on the metal wall sheet (4) as extrusion press stampings, which reduce the original thickness of the metal wall sheets (4), in the form of outwardly directed gas-side ribs (1) running parallel to one another, in relation to which, on the water side in the region below the respective rib feet (2), correspondingly running grooves (3) are formed in the metal wall sheets (4) of the flat tube, the depth (T) of the undulations being dimensioned smaller than the height (H) of the ribs and the distance (A) of the ribs (1) from one another being the same or approximately the same as the height (H) of the ribs. <IMAGE>

Abstract: A sealing arrangement and an associated sealing element (24) are used for sealing two parts, especially for sealing two hollow transmission shafts (10, 12) which can rotate with respect to one another. The sleeve-like sealing element (24) has at least one end side (26) constructed as a sealing surface. Furthermore, a spring element which is pretensioned against the sealing surface is provided. In order to ensure reliable sealing irrespective of the pressure ratios and to prevent friction losses and wear on the sealing surface, a spring element (36) is provided which loses its spring pretensioning at elevated temperatures. The spring force of the spring element (36) is intended to be effective at least during initial assembly. At the operating temperature of the parts (10, 12), the spring element (36) in contrast loses its spring force. The at least one spring element (34) is preferably integrally formed on the sealing element (24) and constructed as an axially extending tab.

Abstract: A starter system for an internal combustion engine having a casing provided with a mounting circumferential surface adapted to be substantially closely fitted into an associated mounting bore provided in the engine or a transmission housing associated therewith, and a mounting flange extending radially from the casing and provided with a mounting end surface perpendicular to a longitudinal line of the output shaft of the starter system and spaced from the mounting circumferential surface along the longitudinal line. Because of the presence of the distance between the mounting end surface of the mounting flange and the mounting circumferential surface of the starter casing closely fitted into the mounting bore, the reaction force acting on the pinion is prevented from being amplified and transmitted to the mounting surfaces by means of an undesirable lever action.

Abstract: An optical disk data storage system utilizes a plurality of substantially parallel interrogating light beams to simultaneously read data from an equal number of data-storing formations at a surface of a storage disk. Preferably, an even number of data-track-reading light beams are utilized, with an additional central beam being used for reading a pre-formatted tracking formation, allowing the reading beams to remain centered upon the associated data formations. A laser-like source provides a single output beam which is split, as by a grating and the like, to provide a plurality of simultaneous, substantially continuous beams. In a system in which data can be written to the optical disk, a plurality of writing light beams, each having data different from the data contained in any other writing light beam, is assigned and utilized to write a different data stream to an associated one of the plurality of readable formations. A central pilot track is illuminated to generate tracking error and focus error signals which are fed back through the system to keep each of the pair of reading beams tracking along, and focused upon, the associated one of the pair of readable data formations.

Abstract: An improved curved-plate, double-hull tanker construction is provided, having reduced or eliminated transverse reinforcing structure in its midbody (224), except for bulkheads (210). The hull, though double, can compare in weight to conventional single hulls, despite being entirely made of mild steel plate. It is made of significantly fewer pieces, with a reduction in welding footage. More of the steel is used in the form of plate (24, 54), rather than more expensive shapes. Improved productivity is possible, resulting from standardization of parts, less scrap, greater use of jigs and fixtures, automated welding, blast-cleaning and painting, so that not so much staging is needed, the work environment can be safer, and the product can be produced at a lower unit labor cost. Preferably, cathodic epoxy painting (124, 126) is used for durability and reduction in problems due to blast cleaning, solvent evaporation and generation of refuse. Extending the double hull structure (236) from the bottom and sides of the hull to the main deck can provide space for fuel oil to be located safely away from the skin of the ship, rather than in possibly vulnerable deep tanks at the stern. The constructional technique is believed to be applicable to vessel hulls (236) in the 70,000 DWT to 300,000 DWT range. The vessel hull midbody module subassemblies (182) may be assembled into modules (212), hull midbodies (224) and vessels (236).

Title: Gearing system.
Inventor: YOUNG NIELS O
IPC: F16D3/18
Filed: 1991-02-19
Abstract: A gearing system includes a pair of gear support plates arranged to rotate about parallel but offset axes with the plates extending parallel to each other in parallel radially extending plates. Each plate includes axially extending teeth in the form of sections of lune shaped elements having concave and convex opposed surfaces. The teeth are interdigited axially such that various pairs of interdigited teeth will be in cooperating surface contact. Rotation of each support plate about its own axis causes the teeth to orbit relative to each other and engage in a driving relationship in a smooth manner, with the convex portion of certain teeth engaging smoothly with the concave portion of adjacent teeth. The gearing system provides a 1:1 speed ratio and has application as an Oldham coupling or synchronizer for a scroll fluid device.

Title: Television set with separate processing of luminance signals and chrominance signals.
Inventor: KAADEN JUERGEN
IPC: H04N9/77
Filed: 1991-03-02
Abstract: The luminance signal (Y) generally has a greater bandwidth and therefore a shorter transit time than the chrominance signal. To compensate this difference in transit time, a retardation stage must be provided in the path of the chrominance signal (Y). For a luminance signal of high bandwidth, this is a relatively complex and costly component. The aim is to simplify this harmonization of the transit times of luminance signal and chrominance signal. To equalize the transit times, instead of the luminance signal being retarded, the chrominance signals are read at higher speed from memories (M2, M3) during a time interval which is not visible in the picture. The present invention is particularly suitable for image storage devices for HDTV sets with high picture frequency and/or line frequency.
