Patent NO-174983-B (NO)
Inventor: FAHRNI HEINZ
IPC: F24F7/007
Filed: 1990-07-20
Abstract: For the controlled ventilation of a room a duct portion (8) with a quantity control and measurement means is provided in the ventilating duct. The duct portion (8) surrounds a tubular hollow body (25) in the form of a flow body, which has two pressure measuring chambers (29, 30) arranged successively in the flow direction. They are provided with rows of openings (27, 28), which produce a connection to the flow cross-sections with different flow speeds. The quantity is measured by means of a differential pressure measuring device (20), which is connected by means of ducts (32, 33) to the pressure measuring chambers (29, 30). The apparatus has low flow losses and a low flow noise. As a result of its favorable flow guidance the apparatus can be positioned directly adjacent to branches of the ventilation duct.

Title: Carbon fibrils,method for producing same,and compositions containing same
Inventor: TENNETT HOWARD G
IPC: B32B9/00
Filed: 1985-12-04
Abstract: This invention concerns an essentially cylindrical discrete carbon fibril characterized by a substantially constant diameter between about 3.5 and about 70 nanometers, e.g. between about 7 and 25 nanometers, length greater than about 102 times the diameter, an outer region of multiple essentially continuous layers of ordered carbon atoms and a distinct inner core region, each of the layers and core disposed substantially concentrically about the cylindrical axis of the fibril. Preferably the entire fibril is substantially free of thermal carbon overcoat. The invention further concerns a plurality of such fibrils. The fibril or plurality of fibrils of this invention may be produced by contacting for an appropriate period of time and at suitable pressure a suitable metal-containing particle with a suitable gaseous, carbon-containing compound, at a temperature between about 850 DEG  C. and 1200 DEG  C., the ratio on a dry weight basis of carbon-containing compound to metal containing particle being at least about 100:1. The fibrils are useful in composites having a matrix of e.g., an organic polymer, an inorganic polymer or a metal. In one embodiment the fibrils are incorporated into structural materials in a method of reinforcement. In other embodiments the fibrils may be used to enhance the electrical or thermal conductivity of a material, to increase the surface area of an electrode or capacitor plate, to provide a support for a catalyst, or to shield an object from electromagnetic radiation.

Title: Activated rnase l as a marker for viral infections
Inventor: CARTER WILLIAM A
IPC: C12Q1/70
Filed: 1988-03-02
Abstract: A first line of cellular defense against many viruses, including those causing AIDS, is activation of an intracellular biochemical system termed the 2'-5' oligoadenylate/RNase L pathway. It is well known that this pathway malfunctions in individuals with progressive AIDs-related immune dysfunction, but the mechanism of malfunction remained obscure. An inhibitor substance, released in HIV infected cells or a virus directed inhibitor of biochemical intermediates in the 2'-5'A/RNase L pathway, Which by apparently physically attaching to the terminal product (RNase L) in the biochemical pathway, causes the entire system to malfunction which thus allows HIV to multiply uncontrollably has now been identified. The relative intracellular level of this newly-isolated inhibitor has prognostic significance with respect to the development of full-blown AIDS and eventual death.
