Patent CA-2093232-A1 (CA)
Inventor: BATTIGELLI JEAN
IPC: C22C32/00
Filed: 1992-08-03
Abstract: The only methods hitherto available for the production of mineral wool from materials such as basalt either utilize a stationary nozzle (blast drawing method) or external centrifuging whereby unsatisfactory yield and/or a not entirely satisfactory fiber quality, particularly with regard to a high content of unfiberized components, are achieved. By way of the invention, application of a fiberization method is suggested which, in spite of a high fluidity of the molten mineral material such as basalt, arrives at high quality fibers with a low bead proportion at good yield. This is made possible by selection of specific materials and their fiberization in specific conditions. Whereas fiberization of these fluid materials is carried out in external centrifuging at viscosities of a few tens of poises, fiberization by internal centrifuging at viscosities of more than 100 poises is required, according to the invention, in order to achieve a mineral wool for insulation purposes with a low bead content.

Inventor: CIDON ISRAEL
IPC: H04L12/56
Filed: 1993-05-10
Abstract: A protocol is defined for mixed data/voice/multimedia communications systems to transmit and receive high-priority, real-time traffic over low-speed digital communication links by embedding such high priority traffic in low priority, non-real-time traffic. High priority, real-time packets are thus transmitted without delay by preempting low-priority packets. Low priority, non real-time packets are held during preemption, and lowpriority transmission is automatically resumed after transmission of high priority packets has been completed. A protocol is defined for communications systems to exchangeinformation, at the time that a communication link is activated, defining their link capabilities for handling high priority, real-time packets and to agree on how this high priority traffic will be transmitted on the communication link.

Title: Propulsive thrust ring system
Inventor: LEMONT HAROLD E
IPC: B64C11/00
Filed: 1992-05-28
Abstract: A low-aspect ratio propeller system is provided with a multiple ring structure (42) formed with a plurality of circular or non-circular; annular, narrrow equivalent air foil rings (56.1, 56.2, 56.3; 56.4) which are held by rails (44) in a predetermined relationship with the propeller blades (44). The upstream ping (56.1) is located downstream from the tip vortex of the propeller (44) within the axial span of the propeller. One or more additional downstream-located rings (56.2, 56.3, 56.4) are used so as to provide at least one annular multiple ring-defined pump aperture (60, 62; 64) through or which peripheral vortices generated by the propeller blades (44) or fan blades may enhance the mass flow. These vortices increase thrust beacause their induction action on the rings, (56.1, 56.2, 56.3, 56.4) increase beneficial ring flow circulation. Augmented ring flow reduces the velocities in the expanding wake by increasing the mass flow. The destruction of tip and root vortices reduces noise. The multiple ring structure (42) also serves as a guard.

Title: Alloy coated metal base substrates, such as coated ferrous metal plates
Inventor: HIRAISHI MASAHIRO
IPC: C23C24/00
Filed: 1994-04-25
Abstract: A method is provided for applying a self-fluxing, self-bonding alloy coating of a hard facing alloy in powder form to a ferrous metal plate or substrate of melting point substantially higher than that of the hard facing alloy.  The method comprises providing a plate of a ferrous metal substrate to be coated in which a surface of the plate to be coated is cleaned, e.g., by grit blasting.  A retaining bank is formed substantially about a predetermined periphery of the plate by forming a ridge of a predetermined height on the clean surface to provide a confining zone into which a powder of the hard facing alloy is smoothly applied to a predetermined thickness to provide a composite of the alloy powder and the substrate.  The powder may have an average particle size ranging from about 40 mesh to about 400 mesh (U.S. Standard) e.g., about 80 mesh to about 325 mesh.          Following the application of the alloy powder to the confining zone to provide a composite, the composite is heated under substantially non-oxidizing conditions at a temperature sufficiently high to melt the alloy powder but below the melting temperature of the metal substrate, and thereby provide a dense alloy coating bonded to the ferrous metal plate or substrate.          The coated plate is then cooled under substantially non-oxidizing conditions to solidify the coa\ting.
