Abstract: The amount of unsolicited bulk e-mail messages received by an e-mail user is reduced by providing the user with a temporary e-mail address and a permanent e-mail address. The temporary addresses are generated by a server on an ongoing basis. The current temporary address is linked to the permanent e-mail address such that e-mail messages sent to the current temporary address are forwarded to the permanent address and e-mail messages sent to a former temporary address are not forwarded to the permanent address and not received by the user. The method and system also provide a degree of anonymity to the e-mail user.

Abstract: The invention provides a removable and reusable door frame guard for a door frame comprising a door jamb, door stop and trim molding attached to a plaster wall. The guard comprises an elongated member having a substantially planar web with depending parallel side panels normal to the planar web. One or both of the side panels terminate with two right angled flanges adaptable for a gripping action with the trim molding and plaster wall. For the hinge side, one side panel has a width about equal to the width of the door stop and about terminates at the jamb, and this narrow panel is adaptable to abut the side of the door stop, as well as the jamb along the marginal edge, thereby providing a gripping action at this side of the guard. Thus, when the guard component is installed over the door frame, the elongated member is adaptable to at least partially engage the door jamb and abut the door stop, and at least one side of the guard is adaptable to grip the trim molding.

Abstract: A die and a method for forming a die to produce optically varying effects in a light reflective surface. A design generally formed as a plurality of parallel grooves of varying widths and depths are engraved in a soft metal foil adhered to a substrate. A hard metal coating is formed on the engraved soft metal foil in a metal plating bath. The hard metal coating, removed from the soft metal foil provides a die formed as a mirror image of the grooves engraved in the soft metal foil. The die is used to deform a reflective surface such that the surface produces optically varying effects. A die formed in the same manner with further processing is used to both deform a reflective surface and hot stamp it to a substrate.

Abstract: A voltage regulator is described adapted for use controlling the output of an AC generator. A voltage control field-winding excitation control circuit supplies direct current to the generator field in response to a driver. The driver, in turn, is operated in response to a switching regulator. A frequency sensing means generates a voltage proportional to the frequency of the generator. This frequency sensitive voltage is combined with a reference voltage to drive an asynchronous switching regulator. The switching regulator produces a train of output voltage control signals to operate the driver. Preferably power MOSFETs are used to control the flow of current to the generator field. Loss of voltage and high current protection features are included.
