Abstract: Clearing landmines is a dangerous activity and the danger is increased when trying to clear a landmine without triggering an explosion. An excavator for landmines is provided, which includes a first actuator that vertically moves a mounting plate. Two or more secondary actuators are mounted to the mounting plate, and each of the secondary actuators are able to extend and retract a tool. Each respective tool has drill bits or prongs for penetrating a ground surface. A neutralizer is also provided, and it includes: a robotic clamp to grip a landmine and to reposition the same; a cutting tool to cut an opening into the landmine; a steaming module to eject steam into the opening; and a catcher to collect melted explosive material that exits the landmine.

Abstract: A toy appendage assembly includes an elongated member, an offset shaft having a first end coupled to a coupling end of the elongated member, and a wheel coupled to a second end of the offset shaft. The offset shaft is coupled to the wheel at a location away from the center of the wheel. The coupling end of the elongated member is at least partially spherical in shape and is capable of rotating within a support structure. The elongated member has a first axis, and the offset shaft has a second axis, where the first axis is angularly offset from the second axis. The coupling end serves as a pivot point for the elongated member and the offset shaft.

Abstract: The present invention is concerned with a scroll wall arrangement for a scroll compressor. The scroll wall arrangement comprises a fixed scroll having fixed scroll walls and an orbiting scroll having orbiting scroll wall. Scroll wall arrangement has an inlet at a radially outer portion thereof and an outlet at a radially central portion thereof. A first flow path is defined by the orbiting and fixed scroll walls and extends from the inlet to the outlet, gas entering the arrangement through inlet at a first pressure and exhausting through outlet at a second pressure higher than the first pressure. Scroll wall arrangement comprises a second inlet through which gas can enter at a third pressure and follow a second fluid path where it is exhausted through the outlet at the second pressure. Two flow paths are thus provided having respective inlets. The third pressure at which gas enters through inlet is different from the first pressure, and lower than the second pressure.

Abstract: A method of assembling a scroll pump comprises the following steps carried out sequentially: the step of mounting a first bearing means (20) and drive shaft (14) for rotation relative to a housing (12): the step of fastening a first flange portion (48) of a bellows arrangement (34) relative to the housing (12); the step of fastening an orbiting scroll (26) to a second flange portion (56) of the bellows arrangement (34): and the step of fixing a second scroll (28) relative to the housing (12) for co-operation with the orbiting scroll (26). The second flange portion (56) is fastened to the orbiting scroll (26) with fasteners (60) which extend through a through-bore (61) in the orbiting scroll and engage with the second flange portion.

Abstract: An electronic throttle control system having a housing 22 with a motor 40, throttle valve 60, gear mechanism 100, and failsafe mechanism. A main spring member 130 positioned between the housing 22 and a gear mechanism 104, which in turn is attached to the throttle valve shaft 62, biases the throttle plate 60 towards the closed position. A spring-biased default mechanism 132, 134 biases the throttle plate 60 from its closed position to a default or “limp-home” position.

Abstract: An electronic throttle control system having a housing 22 with a motor 40, throttle valve 60, gear mechanism 100, and failsafe mechanism. The failsafe mechanism comprises two springs 130, 150 and two levers 140, 160 which are used in combination with a gear member and an adjustable stop screw 170 on the housing.
