Abstract: A toy vehicle has hinged and lockable doors, trunk lid, and hood, each with an internal U-shaped shackle, clevis, or claw projecting inwardly. A single locking plate is slidably positioned inside the vehicle. The plate has an integral sliding bolt at each position which is adjacent a shackle, clevis, or claw. The internal hub of each wheel has an integral, cam shaped member formed thereon to be captured or released by detents on the locking plate. A key fits through a key hole in the bottom of the vehicle in order to slide the plate forward or aft, as the key turns. As it so slides, a bolt or detent on the plate slides through or out of each shackle, clevis, or claw and engages or disengages the cam members, thereby locking or unlocking the doors and wheels.

Abstract: The invention relates to drum processing apparatus for in the treatment of photographic material. The apparatus comprises a stand, a processing drum rotatably mounted on the stand, and means for intermittently axially displacing processing liquid in the drum causing the liquid to oscillate axially in waves traversing the length of the drum. The drum is axially slidable relative the support. During rotation of the drum, it is variably axially displaced against drum biasing means to cause processing liquid in the drum to oscillate axially. The present apparatus, which is simple and convenient to construct, ensures uniform and continuous contact of the processing liquid over the photographic material treated in the drum.
