Abstract: An improved tamper resistant bottle cap and neck for bottles which hold liquid. The bottle cap of the present invention includes a circular cover, a skirt depending from the periphery of the cover, and a tamper evidencing lower portion. A raised ring formed on the outer and upper surface of the bumper roll typically used in blow-molded containers protects the lower edge of the cap from tampering by making the lower edge of the ratchet ring in the case of a thread-on cap (or the lower edge of the removable portion of a skirt in the case of a push-on cap) less accessible to potential tamperers. Thread-on caps with helical threads and a ratchet ring, or push-on caps with skirts having removable lower portions, may each be equipped with an arched or curved pull tab. The pull tab in each instance is designed to accommodate a raised ring on the bumper roll of the neck of a blow-molded bottle. By designing the pull tab to accommodate the raised ring on the bumper roll the presence of the ring does not induce unwanted stresses and deformations into the pull tab or the skirt or ratchet ring to which the pull tab is connected.

Abstract: The surge arrester has an arrester housing, two electrical power connections (16, 17) which are routed out of the arrester housing, and at least one varistor, which is arranged in the arrester housing (1, 2), is in the form of a disc and has two contact points which are provided on the end faces. The contact points are each electrically conductively connected to one of the two electrical power connections (16, 17).      The varistor contains a non-metallized active part (12) and two elastic contact elements (11, 13) which are pressed against the end faces of the active part (12), forming an electrical contact. The end surfaces (12a, 12b) may be convex or concave instead of being plane-parallel and, if they are in the desired plane-parallel form, form a small angle with respect to one another.      The elastic contact elements (11, 13) and the non-metallized end surfaces (12a, 12b) allow good electrical contact in all cases. Since, during manufacture of the active part, the geometric tolerance limits can be kept relatively wide, the surge arrester can be produced extremely cost-effectively.

Filed: 1999-06-08
Abstract: A technique to switch between upper and lowercase alphabetic characters in a wireless communication device measures the period of time in which a numeric key is held in the depressed position by the user.      If a numeric key is pressed by the user for a period of time less than a predetermined threshold time (212), the selected alphabetic character is displayed in a default character case. If the selected numeric key is held in the depressed position for a period of time exceeding the predetermined threshold period, the character case is altered and the altered alphabetic character is displayed for the user (214). The user selects the desired alphabetic character by activating a selected numeric key one or more times corresponding to the desired alphabetic letter. If the selected numeric key is held in the depressed position for a period of time exceeding the threshold period during any of the button depressions (212), the system automatically changes to the altered alphabetic character case (214). The alphabetic character case is controlled on a character by character basis such that entry of a new alphabetic character uses the default character case unless the selected numeric key is again held in the depressed position for a period of time exceeding the predetermined threshold.
