Patent EP-0389097-A2 (EP)
Inventor: HAAS ZYGMUNT
IPC: H04B10/272
Filed: 1990-02-14
Abstract: This invention is directed toward providing higher speed local and/or metropolitan area optical networks by storing light in the fiber of an optical network to resolve collisions between advancing packets. 
     One condition that needs to be resolved in packet-switched networks occurs when two packets attempt to exit a switching node (100,102,104,106) on the same output link. With this invention, collisions of optical packets are resolved by coupling all packets that cannot be forwarded onto the reverse links for transmission to the node they came from. With this invention, each branch of a network, for example, a star type of network, is provided with an optical fiber path (108,110,112) having two parallel opposite-­directed, optical links which can be selectively configured to form either a direct straight throughput or a loop-back path. 
     Prior to advancing a packet to the next occurring path, a test is made to determine if it is occupied with a packet. If it is not occupied, the packet is advanced along the forward optical link to the next node. If it is occupied, then the two optical links of the optical path directed to the previous node are very rapidly configured to form a loop-back path, and the packet is sent around the loop-back path, again and again, as required, until the path to the next node is cleared.

Abstract: A hair conditioning shampoo is described, which contains C 6 , C 8  and/or C 10  alkyl sulfate and/or C 6 , C 8  and/or C 10  alkyl lower alkoxylate sulfate as an anionic detergent component, a water insoluble conditioning agent(s) from the group of silicones (preferably a certain type of aminosilicone), polyethylenes, paraffins, isoparaffins, microcrystalline waxes, C 18-36(mixed)  fatty acids or such triglycerides, high fatty alcohol esters of a high fatty acid (such as stearyl stearate), beeswax, cationic conditioning agent, such as a quatenary ammonium or any mixture thereof, and a stablilizer for the shampoo, in water. Among adjuvants that may be present are lauric monoethanolamide, cocodiethanolamide, and hydroxyethyl cellulose, other thickeners and viscosity modifiers, pH adjusting agents, antioxidants, perfumes and colorants. The presence of the C 6 , Cs and/or C 10  alkyl sulfate and/or C 6 , C 8  and/or C 10  alkyl lower alkoxylated sulfate surprisingly improves conditioning of the hair, compared to shampoos containing other detergents that contain longer chain alkyl groups.

Abstract: A tipped annular hole cutter is made by brazing all the cutting tips (30) simultaneously to the cylindrical wall (12) of the cutter body. The tips (30) have outer and inner lands (32, 34) which locate against the outer and inner surfaces (52, 54) of the cylindrical wall (12). This accurately locates the tips radially during brazing. The radially inner face (46) of the tip (30) is inclined so as to define an inner clearance face which has the necessary circumferential and radial clearances without there being any need to grind the inner face (46) after brazing. 
     The tips (30) are received in skewed slots (18) whose angle of skew (alpha) is less than the angle of spiral (beta) of the flutes (70). The front rake face (43) is ground to provide an optimum cutting action whereas the flutes are designed independently to achieve optimum chip removal.

Abstract: A processor (302) presents a sequence of images of a workspace that is stretched to enable the user to view a part of the workspace in greater detail. The workspace includes a middle section (20) and two peripheral sections (22, 24) that meet the middle section on opposite edges. Each of the sections appears to be a rectangular two-dimensional surface and they are perceptible in three dimensions. When the user is viewing the middle section as if it were parallel to the display screen surface, each peripheral section appears to extend away from the user at an angle from the edge of the middle section so that the peripheral sections occupy relatively little of the screen. When the user requests stretching, the middle section is stretched and the peripheral sections are compressed to accommodate the stretching. When the user shrinking, the middle section is shrunk and the peripheral sections are expanded accordingly. The workspace includes display objects that may cross the edges from the middle section to the peripheral sections during stretching. Stretching and shrinking are performed in small steps to preserve object constancy for display objects that cross the edges. The display objects can have fixed sizes, in which case each display object is perceived as being tacked to the workspace at a point. Alternatively the display objects may stretch and shrink with the workspace, in which case additional internal detail may become visible as a result of stretching, and each display object is perceived as being glued to the workspace over its entire extent. Additional display objects can become visible as a result of stretching.

Abstract: A method of monitoring a plating bath which combines ac and dc voltammetry to accurately measure major and trace constituent concentrations. The method involves applying both ac and dc voltammetric signals to a pretreated electrode in contact with the plating bath solution, measuring the ac and dc response current spectra, and comparing the resultant spectra to determine which provides maximum spectral detail for monitoring particular constituents with minimum interference from other constituents. Then, the ac and dc response current spectra are each used to monitor the particular constituents for which each provides the best accuracy. The method complements and is easily integrated with known voltammetric techniques and equipment.
