Patent EP-0279913-A2 (EP)
Inventor: JANSSEN HERMANN-JOSEF
IPC: F23C7/00
Filed: 1987-11-10
Abstract: A burner for burning liquid or gaseous fuels, especially heavy heating oil. A central fuel lance is surrounded by two annular channels that supply primary and secondary combustion air. The annular channels are surrounded by several outer fuel lances that are distributed along the arc of a circle and can optionally be displaced axially and by air nozzles that convey tertiary combustion air. The object is to burn fuel at a low output of pollutants in systems with a narrow combustion space. The burner has an annular flue-gas channel between the outer annular channel and the air nozzles. The burner opens into a chamber that is jacketed in ceramic and that a heat exchanger (flame tube) extends out of. Other nozzles that convey a component of the flow of tertiary air are mounted in the wall of the chamber.

Abstract: A manual sweeping apparatus comprising a housing, rollers which can rotate in contact with an original or a sheet of paper, an image sensor (15), a printer (21 memories (57), and a key-input section (53). When the housing is swept across an original (B), with the rollers kept in contact with the original (B), the image sensor reads (15) the image information from the original (B). The image information is stored in one of the memories (57). Character data is input by operating the key-input section (53), and is stored in another one of the memories (63). Thereafter, when the housing is swept across a sheet of paper, with the rollers kept in contact with the paper, both the image data and the character data are printed, in a combined form, on the sheet of paper.

These compounds comprise a specific type of UVA-absorbing chromophore covalently bonded to a specific type of UVB-absorbing chromophore. The chromophore moieties are covalently bonded together such that the electron systems of these moieties are directly coupled to thereby form a new chromophore. 
     The present invention further relates to sunscreen compositions containing the hereinbefore described type of sunscreen agents. Furthermore, the present invention relates to methods for protecting the skin of humans or lower animals from the effects of UVA and UVB wavelength radiation. This method comprises topically applying to the skin an effective coating of a sunscreen composition of the present invention.

Abstract: A fracturable x-y random access memory array for performing pushing and popping of data and fracturing the array simultaneously at a common address includes a row fracture circuit responsive to row addresses to fracture the array in the Y-direction and a column fracture circuit responsive to column addresses for fracturing the array in the X-direction. A plurality of memory cells are stacked in a plurality of columns to form an x-y organization which can be randomly accessed in response to the row and column addresses. The memory cells are responsive to a shift control driver circuit for bidirectional shifting of data by either pushing data into or popping data from at any point within one of the plurality of randomly addressable column at the same row and column addresses used to fracture the array defining a fracture point. Data in all the memory cells in the array with addresses higher (or lower) than the fracture point shift and the memory cells with addresses lower (or higher) than the fracture point maintain their data unchanged. A unique memory cell is also provided which is formed of a pair of cross-coupled latches which includes means for controlling a bidirectional shift by switching off power to one of the cross-coupled latches.

Abstract: A process for forming a plastic part (10) having a tubular portion (14) that is continuous and without any flash/mismatch due to mold parting lines in which an injec­tion mold is provided having a cavity formed with a cylindri­cal surface portion (24) and a core member (22) removably inserted endwise into the cylindrical portion. A molten plastic material is injected into the cavity so that it extends into the cylindrical portion (24) and around the core member (22). The core member is then withdrawn in an axial direction from the cylindrical portion after the plastic material therein has solidified enough to retain its tubular shape but before it has completely cooled to thereby enable the plastic material to shrink radially inwardly away from the cylindrical surface. Thereafter, the molded tubular shape (14) and the cylindrical mold surface (24) are moved relative to each other in an axial direction so that they are moved away from each other and the tubular portion is withdrawn from the mold, with the tubular portion yielding or flexing to whatever extent is necessary in order to clear the mold.

Abstract: In a process for the production of refractory mouldings based on dead-burnt dolomite and/or dead-burnt lime, even with enrichment by magnesium oxide, and with addition of a carbon-containing binder in amounts by weight of up to 6%, and a further addition of carbon in amounts by weight of from 0 to 20%, the advantages of high-temperature conditioning are utilised, but the loss of carbon is avoided and the shelf life of the refractory mouldings obtained is increased. This is achieved by subjecting mouldings to heat treatment up to 800 DEG C in a furnace whose atmosphere contains < 2% by volume of oxygen and > 8% by volume of carbon dioxide (CO2). Basic, refractory mouldings are obtained which emit virtually no smoke on heating when used in metallurgical vessels, in particular pans for steel treatment.
