  • Patent number: 7377860
    Abstract: An improved golf club head is disclosed which comprises the positioning of secondary weights at such low, rearward and outward locations that it causes an alteration in the traditional look of the club head wherein each secondary weight has a portion of the weight that bulges outwards of the natural contour of the club head.

  • Patent number: 5936505
    Abstract: A circuit breaker has a body providing a lever pivotally mounted on the upper end thereof. Two terminals are disposed within the body, wherein the first terminal forms a bimetal thereon. The terminals are electrically connected with each other in a normal state. A linkage is mounted on an end of the lever, which forms an isolated member on the lower end of the linkage. Pressing the lever, the isolated member of the linkage will moved upwards to separate the two terminals. When the lever is held by some heavy substances, the bimetal can be deformed to disconnect with the second terminal in over-current for cutting out the circuit.

  • Patent number: 5933069
    Abstract: An electrical breaker includes a casing with a pushbutton pivotally connected to the top thereof, an alloy plate extending from one of two inside walls of the casing and connected to a first prong extending from the casing, a push member and an L-shaped member pivotally connected to the first end of the pushbutton, a biasing member biasing the push member to let the protrusion of the push member press against the other inside wall which has a recess defined therein. The distal end of the alloy plate is pushed by the push member to contact the second prong when the first end of the pushbutton is pushed, and the distal end of the alloy plate is disengaged from the second prong by the horizontal portion of the L-shaped member when an overload current passes through the alloy plate which curves to push the first end of the pushbutton upwardly.

  • Patent number: 5892426
    Abstract: A titterboard type switch with security structure, wherein a relay unit is disposed between two terminal legs connected with power wires and an electrothermal conductor is connected between the relay unit and one of the terminal legs, whereby when powered on, the electrothermal conductor is slightly heated and in the case of overload, the electrothermal conductor creates high temperature. The relay unit is disposed with a resilient movable contact pushable by a sliding member for controlling whether the movable contact contacts with the other terminal leg or not. The sliding plate is pushed by a swinging plate which is shifted by a push button via a linking unit.

  • Patent number: 4424422
    Abstract: A thermostatically controlled electric fuel heater for raising the temperature of diesel fuel flowing from a fuel tank to a fuel filter to prevent precipitation of wax crystals in the fuel filter and consequent filter clogging at low ambient temperatures includes a heat conductive tube incorporated as part of the fuel line a short distance upstream of the filter. An electric heating assembly is positioned on the tube and includes an electric resistance heating element helically wound about the tube and controlled by a thermostat responsive to the temperature of the tube and located upstream from the heating element. The thermostat includes a molded plastic frame having a central opening through which the tube passes. The thermostat includes a bimetallic thermal element secured to the frame and arranged to actuate a snap-action switch carried by the frame. The frame includes a baffle for thermally isolating the thermal element from the heating element.

  • Patent number: 4144427
    Abstract: A single pole molded case circuit breaker having a spring powered trip free contact operating mechanism including an extendable toggle connected at one end to a releasable cradle and connected at the other end to a movable contact, a latch for holding the cradle in reset position, and an automatic trip means for operating the latch to release the cradle upon the occurrence of predetermined overload conditions, is provided with anti-rebound means which prevents the movable contact from moving toward closed circuit position except under the influence of the operating mechanism. The anti-rebound means includes engaging formations of the cradle and toggle which cooperate to block the toggle from being extended unless the cradle is in its reset position. As the cradle moves to trip position it engages the toggle to kick the contact arm toward open position.

  • Patent number: 4008453
    Abstract: A thermal change-over switch has a switch arm movable between first and second contact positions with an intervening dead center position, a temperature responsive bimetal element is connected to the switch arm through a prestressed resilient element so as to effect quick switch-over of the arm from either position to the other while maintaining contact pressure up to the time of switch-over.
