Title: Terminal for battery electrodes
Inventor: SUZUKI MASAO
IPC: H01R13/24
Filed: 1995-12-18
Abstract: The present device provides a terminal mounted on the surface  of  a  printed  circuit  board  and,   more particularly, to a terminal used for reliably contacting the electrodes of a battery.  In a terminal comprising a housing and a plurality of spring contacts mounted in the housing, the curved parts of the spring sections of the spring contacts extend externally from one surface of the housing in different arrangement.   Since the positions of the curved parts are different, the spring actions of the contacts against the contact target members are not localized.   Even if the shape of the contact target members varies largely, these members can be held reliably.

Patent CA-2179463-A1 (CA)
Title: Technique and apparatus for measuring a direct current flowing through a conductor at high voltage
Inventor: LABRIOLA DONALD P II
IPC: G01R15/22
Filed: 1996-06-19
Abstract: A technique and circuit for measuring direct current flowing through a conductor at a high voltage employs a capacitor connected in series with the conductor, and a neon lamp connected in parallel with the capacitor. The series connected capacitor and conductor are connected to a high voltage source such that the current flowing through the series connected capacitor and conductor charges up the capacitor. Since the capacitor and the neon lamp are connected in parallel, the voltage across the electrodes of the neon lamp follows the voltage across the capacitor. When the voltage across the electrodes of the neon lamp reaches the lamp's ignition voltage, the neon lamp fires, and discharges the capacitor until the voltage across the electrodes of the neon lamp falls to the lamp's extinction voltage. The light signal generated by the neon lamp is picked up by a fiber optic cable and transmitted to a remote receiver for processing.  The direct current flowing through the conductor may then be calculated by the remote receiver from the frequency of the transmitted light signal, or a qualitative indication of the current may be made through visual observation of the lamp's intensity.

Abstract: A tire tread that is applicable to retread a worn tire carcass. The tire tread includes a cured tread portion having a first shoulder and a second shoulder. A first uncured wing portion extends from the f first shoulder and a second uncured wing portion extends from the second shoulder. Further, an end section at each end of the tire tread portion is uncured. When the tire tread is wrapped around the tire carcass to be formed to the tire carcass and form a tire retread, the first and second wing portions extend down the side walls of the tire carcass and the uncured end sections of the tire tread contact each other.     The tire carcass is placed within an autoclave, and the autoclave is heated under pressure such that the tire tread is cross-linked to the tire carcass. During the autoclaving step, the uncured wing portions are cured and cross-linked to the side walls of the tire carcass, and the uncured end portions are cured and cross-linked to each other. A mold segment is positioned within the tire tread pattern where the end sections of the tire tread meet in order to prevent the tire tread pattern from being damaged at the uncured end sections during the autoclaving process.
