Patent NO-160314-C (NO)
Inventor: BUSCHULTE WINFRIED
IPC: F23D11/40
Filed: 1985-08-15
Abstract: The invention relates to a hot-gas generating burner comprising a nozzle discharging a fuel jet which then enters a mixing tube, and an orifice plate surrounding the outlet of the nozzle. The casing of the burner is divided by the orifice plate into an upstream-disposed precombustion chamber which includes the nozzle, and a downstream combustion chamber which contains the mixing tube. The orifice has a central passage for the fuel jet which is discharged from the nozzle and a number of openings surrounding the passage. In order to reduce the noise concomitant with the operation of the burner, the spacing between the peripheries of the neighboring openings equals at least 50% of the diameter of the openings, and/or the openings in the orifice plate are associated with at least one air duct in the direction of flow.

Title: In vitro and in vivo growth-promoting proteins and peptides for kidney epithelial cells
Inventor: TOBACK F GARY
IPC: C12N5/06
Filed: 1998-05-22
Granted: 2003-01-16
Abstract: Novel growth peptides derived from protein factors having molecular weights of about 22 and 45 kDa stimulate mitogenic activity of epithelial, but not fibroblastic cells, in particular, kidney epithelial cells. A source of the factors is scrape-wounded kidney epithelial cells in culture. Synthetic peptides having sixteen amino acids or less, in particular a hexapeptide, YPQGNH (SEQ ID NO: 2) maintain the mitogenic activity. The peptide AQPYPQGNHEASYG (14-Ser) (SEQ ID NO: 15) is effective in reversing acute renal failure in animals. The growth-promoting characteristics of the 22 and 45 kDa proteins and the peptides are useful in treating and diagnosing patients with kidney disease. Nucleotide sequences that encode the factor are useful to develop probes to locate similar factors, to identify genetic disorders involving the factor, and to produce the factor by genetic recombinant methods. The nucleotide sequences and fragments thereof, are also useful for diagnosis and treatment of kidney disorders.

Abstract: The invention relates to an indicator device for an indicator formed of individual indicator elements, where an optical fiber having an associated bore in an indicator board located in front of the indicator elements is assigned to each indicator element, with switching elements between the ends of the optical fibers and the associated bores of the indicator board, which are assigned to the individual optical fibers, which switching elements can be selectively brought into a non-indicating position by means of electromagnets, where they cover the end of the assigned optical fibers, or into an indicating position, where the optical fiber is uncovered.  This indicator device can be utilized in a simple manner for displaying arbitrary luminous signals in that each optical fiber is closed off by a reflecting body which extends into a compartment of a housing open in the direction of the indicator board and which is held in a hole in the bottom of the compartment, that the switch element is embodied as a flap, which is rotatably seated with its rotational axis in the area of the open side of the compartment and which covers the open side of the compartment in the non-indicating position, that the reflecting body is disposed outside of the rotational axis of the flap and is used laterally as a stop for limiting the rotational movement of the flap to approximately 90°, and approximately one half of which is pivoted into the compartment in the indicating position, so that the end of the reflecting body is uncovered, and that a light collector is fixed in the associated bore of the indicator board, which is embodied as a section of a solid body made of glass or a transparent plastic material and at least the front face of which facing the reflecting body is polished.
