Abstract: A weight for correcting imbalance in a rotary element includes a number of discrete weights. The number of discrete weights is selected to substantially correct the imbalance. A piece of double sided tape has sufficient length for the number of discrete weights to be adhered to the length of double sided tape. A removable film protects the side of the tape opposite the side to which the discrete weights are adhered. The film reduces the likelihood of contamination until the film is removed to expose the side of the tape opposite the side to which the discrete weights are adhered, permitting the weight to be applied to the rotary element.

Abstract: L'invention concerne un procédé et un système utilisables pour la fourniture de services géographiques spécifiques à un récepteur (4), dans un réseau de télécommunications par satellite: en l'occurrence, on utilise l'information de localisation d'emplacement véhiculée par un signal composite que transmet un répéteur terrestre (3). Le répéteur en question reçoit par satellite ledit signal composite, établi sur plusieurs voies de données à multiplexage temporel, et il retransmet ce signal avec un numéro d'identification d'émetteur unique fournissant l'identité du répéteur (21). A la réception du signal composite depuis le répéteur terrestre, le récepteur détermine l'emplacement géographique courant du récepteur sur la base du numéro d'identification de l'émetteur (24). Ensuite, le récepteur compare l'emplacement courant du récepteur et l'information d'en-tête acheminée dans les voies de données pour sélectionner l'information dans les voies de données correspondant à l'emplacement géographique du récepteur (25), moyennant quoi le récepteur fournit l'information sélectionnée à un utilisateur du récepteur.

Abstract: A bond for.a.metal single layer abrasive tool can be easily chemically and electrochemically stripped from the metal core of a recovered used tool to facilitate reuse of the core. Relative to conventionally bonded tools, the speed of stripping the novel bond is quick, and the stripped core has a smooth, clean surface which needs only minimal mechanical repair prior to reuse. The composition of the novel bond consists essentially of copper, tin and titanium. It can be brazed at temperatures below diamond graphitization and is chemically compatible with diamond.        Hence, the bond is particularly useful for the manufacture of large diameter, superabrasive metal single layer abrasive wheels employed in the construction industry.      The bond can be applied to the cutting surface of the abrasive tool as a uniform mixture of bronze alloy, titanium compound and copper powders. The powders may be mixed with a liquid vehicle and applied as a paste. The method. of brazing the bond incorporates heating the bond composition to a temperature at most about 880°C to melt the bronze alloy and titanium compound components, and raising the temperature to at least about 900°C to dissolve the copper. The bond can also include an about 10-200 µm thick barrier layer of copper coating the cutting surface between the core and the bond composition.

Title: Rehalftoning of gray halftones with optimal screen frequency for robust suppression of moire
Inventor: XU BEILEI
IPC: G06T5/40
Filed: 2003-05-14
Granted: 2008-08-12
Abstract: Optimal rehalftone screen frequencies are found by searching frequency space for points that are maximally spaced from significant frequency components of an input image halftone screen or screens. Selecting a rehalftone screen having a maximally spaced frequency produces more of the highest frequency possible. High frequency moiré are visually unobjectionable. Optimal rehalftone frequencies may be found near the maximally spaced points where system or other constraints limit the usefulness of the maximally spaced points. Rehalftone screen frequencies in the range of about 1.4 to about 1.8 times the fundamental frequency of the input image halftone screen are often optimal. A rehalftone screen frequency of 1.5 times the fundamental frequency of the input image halftone screen is often optimal when the input image is monochrome and uses a dot screen.
