Abstract: The invention relates to a furnace assembly adapted for the combustion of wastes. Its grating is arranged tiltable and a mass of mineral particles is mounted on the latter and for acting as a provisional and stationary furnace bed.

Abstract: A toy moving car is a toy car operated by a wireless electric device and comprises a car and a wireless electric transmitter in separation. All means including a driving means and a braking means are mounted on a bottom plate of the car. A pair of front wheels of the driving means are mounted on a front axle which is journaled in both sides of an axle support frame. The axle support frame is pivoted on the bottom plate. The braking means comprises a receiver, an electromagnet and a pair of brake disks. A sliding frame is adapted to slide laterally on the axle support frame and is equipped with the electromagnet having a pair of magnet cores. Each of the brake disks is fixed to each inside surface of the front wheels by a leaf-spring as a buffer. During a time that the receiver is receiving the electric wave from the transmitter, the electromagnet works and either one of the magnet cores which is closer to one of the brake disks sticks to said one brake disk.

Abstract: A self-powered toy animal comprises a relatively small toy animal and a relatively large toy animal having an openable mouth. Drive means is provided inside one of the animals connected to a line having its other end connected to the other animal and passing through the mouth of the large animal. In addition, the large animal has a pair of eyes provided with lids which automatically close when the mouth opens. This large animal, which may be constituted as a fish or the like, will therefore appear to pursue and then eat the small animal as it pulls the small animal into its openable mouth, simultaneously closing its eyes as the small animal passes through the mouth into the interior of the large animal.

Abstract: A toy has an upright hollow rectangular-section tower formed at one side at its upper end with an exit opening and on the other side at its lower end with an entrance opening. An inclined ramp has an upper end at the exit opening and a lower end at the entrance opening and there is provided at this entrance opening a pivotal flap which prevents air exiting from the tower but allows a small toy motor car which is displaceable along the ramp to move through the door into the tower. An elevator is vertically displaceable in the tower and has a bottom wall adapted to support the car and inclined from the entrance-opening side of the tower toward the exit-opening side of the tower.

Abstract: A guide follower of a vehicle for a transportation system is coupled to an onboard steering linkage by a bendable cable or equivalent. The bendable cable is taut to transfer the guide following movement of the guide follower to the steering linkage and is relaxed to disconnect the movement transmitting connection between them.

Abstract: Oxides of nitrogen can be removed efficiently from a gas containing such oxides of nitrogen by bringing said gas into contact with an aqueous solution containing an organic acid alkali salt and a salt of metal selected from the group consisting of Fe, Co, Ni, Cu and Mn in the presence of a sulfurous acid alkali salt. The efficiency for removing oxides of nitrogen is much improved by use of a polybasic acid alkali such as ethylenediamine tetracarboxylic acid alkali salt or nitrilo-tricarboxylic acid alkali salt as said organic acid alkali salt.
