Abstract: An ammunition magazine for dispensing uniformly-sized spherical projectiles such as paintballs into a gun adapted to shoot said projectiles has a generally oblong, closed container having a channel defined in its bottom from a distal axial end to an outlet port located in a lowermost, median portion of the container. The proximal portion of the container floor defines a slanted platform which extends above and beyond the outer port so that projectiles are urged by the platform toward the distal end of the channel from where they roll under the platform and into the outlet port. A helicoidal stirring arm projects from a distal area of the platform obliquely over the exposed part of the channel. The steering arm is driven by an electrical motor controlled by a switch conveniently mounted on the side of the magazine. The arm spins in a ball-uplifting direction to break any jamming of the balls above the channel.

Abstract: A portable, organized carrier for holding a variety of odd-sized goods includes two sets of layered, co-nesting, pocket-mounting flaps foldable around a comparted core area. The folded flaps are capped and clamped together by a pair of shell-like covers mounted at opposite longitudinal ends of the carrier. Shoulder and waist straps as well as a handle allow for use of the carrier as a backpack or a tote bag.

Abstract: An articulated device for protecting the knee as well as above-the-knee and below-the-knee leg portions comprises a first part shaped and dimensioned to cup the knee and cradle a small section of the leg above it. A second part forming a greave for the below-the-knee portion of the leg is slidingly connected to a longitudinal plate which is hinged at its top to the lower edge of the first part. An adjustable elastomeric strap biases the second part away from the first part, allowing the two parts to move axially in relation to one another during flexion and extension of the knee, while keeping the device tautly against the leg and knee at all times.
