Abstract: A toy hand grenade has a plurality of bores which receive soft darts. A launcher is received in each bore and is spring loaded. An actuator retains the launchers in a spring-loaded, unactuated position. The actuator is displaceable relative to the body to release the launchers and substantially concurrently eject the darts from the hand grenade. A pin or a clip may be employed to lock the actuator in a locked position. A timer is employed to delay actuation of the actuator to release the launchers and eject the darts from the hand grenade. A sandbag ring is imposed to ensure proper orientation and stability of the hand grenade for the timer actuated feature.

Abstract: A fuel pump module with an inlet fuel filter has a vapor inlet in communication with the interior of the filter and constructed to reduce the size of larger vapor bubbles trapped within the filter before they are ingested by the fuel pump downstream of the filter to limit the amount of fuel vapor ingested by the fuel pump at one time. Preferably, a tubular inlet sleeve is integrally connected with the fuel filter and press fit onto the inlet of the fuel pump as a subassembly with the vapor inlet passage formed in the inlet sleeve. The vapor inlet passage may be a slot formed in the inlet sleeve providing a reduced area flow path through which vapor in the interior of the filter may pass before entering the fuel pump.

Abstract: A toothbrush employs a bristle guard for the prevention of contamination and deformation of toothbrush bristles. The bristle guard comprises an arm, which is received within, and pivotally connected to, the toothbrush handle. The pivotal connection allows the arm to move between a guard position and a brushing position. In the guard position, the arm extends from the handle and supports the toothbrush in a rack style holder. In the brushing position, the arm is substantially received within the toothbrush handle allowing conventional use.

Abstract: For a fuel pump mounted within a module in a vehicle fuel tank, a stand pipe is provided in communication at its upper end with a return fuel reservoir and at its lower end with the inlet of the fuel pump to deliver fuel from the return fuel reservoir when the level of fuel in the reservoir rises above the upper end of the stand pipe. The return fuel reservoir has an inlet in communication with a fuel return line through which excess fuel in the fuel system is delivered to the return fuel reservoir. This "weathered" return fuel is delivered to the fuel pump inlet through the stand pipe when the level of fuel in the reservoir is sufficiently high to prefer use of the weathered return fuel by the fuel pump.

Abstract: An in-tank fuel pump and reservoir canister module having a fuel filter mounted in the module base adjacent the bottom of the tank and defining a filter chamber having an outlet connected to the inlet of an electric fuel pump received directly in the tank exteriorly alongside of an upright overflow-type reserve fuel canister. A canister bottom outlet is closed by a flow controlling valve and/or by an always-open restricted orifice communicating with the filter chamber for returning engine bypassed reserve fuel from the canister reservoir to the pump inlet, either continuously and/or only when a low level supply of fuel in the tank to the filter is interrupted. The valve is operated by a diaphragm portion of the filter, base-mounted between the canister outlet and filter chamber and also communicating directly with the tank, the valve opening against the bias of a coil spring in response to pump suction acting on a capillary seal formed on the diaphragm filter to thereby allow reserve fuel to flow into the filter chamber. At system shut-down a filter backwash flow can occur from the canister reservoir. The pump rotary vane impeller chamber has an internal vapor purging passageway communicating at its outlet directly with the interior of the tank so as not to be subjected to any anti-purging gravity pressure head differential existing between the fuel level in the canister reservoir versus that of the main body of fuel in the tank.
