Abstract: A toy gun projects matter from a plurality of discharge ports, such as barrels or nozzles, which are irregularly located on the gun. The gun may incorporate a figurine in its structure to simulate an object such as a creature or a vehicle. The discharge ports may simulate a plurality of weapons carried by or on the figurine, such as cannons, machine guns, lasers or the like and may be adapted to project matter in solid or liquid forms, such as darts or water. A pump mechanism pressurizes gas or liquid, typically air or water, to facilitate the discharge of such projected matter. A distribution mechanism conducts the pressurized gas or liquid to the discharge ports.

Abstract: A gun projects matter from a discharge port, such as a barrel or nozzle, that is movably carried, so that the direction of discharge is variable with respect to the body of the gun. A manual direction controlling mechanism may be implemented for the movable discharge port, whereby the variable direction of discharge is directly controlled by a user, or an automatic direction controlling mechanism may be implemented such that the direction of the movable discharge port is automatically varied in response to the operation of a discharge actuating mechanism of the gun. Multiple discharge ports, capable of aiming in multiple directions simultaneously, may be incorporated to facilitate the projection of liquid or solid projectiles toward multiple or moving targets.

Abstract: A toy for projecting water or other fluid matter employs a generally unpredictable discharge actuating mechanism to provide a surprise discharge from a rotatable nozzle. The toy further employs a manually operable discharge stopping mechanism to allow users to strike or press on the toy to stop a discharge once it has begun. A variety of propulsion mechanisms may be employed for rotating the nozzle to allow discharge toward players in multiple directions.

Abstract: A multi-shot airgun employs a hand crank for cocking and firing of an air pump, and advancement of a multi-projectile magazine. Turning the crank causes the pump's plunger to be cycled back and forth to cock and discharge the pump. Turning the crank additionally actuates a projectile advancement mechanism. The advancement mechanism sequentially positions a plurality of projectiles in firing alignment with an air discharge port of the pump. Continuous rotation of the crank results in discharge of the projectiles in rapid succession. A high capacity magazine is provided in the form of a long, continuously looped ammunition belt to allow extended firing time between loadings.

Abstract: Air operated apparatus for successively launching a plurality of projectiles are disclosed.

Abstract: In a simultaneous marking specific binding assay for an analyte is a liquid sample, such as urine during pregnancy or fertile period test, wherein the liquid sample is simultaneously incubated with a first specific binding reagent immobilized on a solid phase carrier surface and with a second specific binding reagent dissolved or dispersed in the liquid sample and which bears a label by means of which the result of the assay can be determined, the improvement that prior to the incubation the second specific binding reagent is contained within a layer (2a) of readily soluble or dispersible solid material superimposed on the solid phase carrier surface (2a) on which the first specific binding reagent is immobilized.

Abstract: A projectile launching device is disclosed herein having, in its simplest form, a single elongated launching tube or barrel, onto the rearward end of which is pivotally mounted a lever assembly having a latch member and a release member coupled to one another about the pivot. The release member extends across the rearward end of the barrel and the latch member extends forwardly along the barrel. The barrel is open at its forward end to receive a shaftlike projectile. A hook is carried at the forward end of the latch member to protrude through a slot radially into the barrel for engagement with a tab on the projectile shaft. A spring, housed inside the barrel, rests against the release member of the lever assembly such that when a projectile is inserted into the barrel it compresses the spring against the release member and pivots the lever assembly to force the hook into the barrel and into engagement with the projectile tab, thereby preventing the spring from ejecting the projectile from the barrel.
