Abstract: A power switch for a battery is disclosed, which includes a battery-receiving chamber having anodic and cathodic contacts for the battery, an aperture provided centrally in the anodic contact, and a switching mechanism having a protrusion which is movable through the aperture relative to the anode of the battery. The switching device comprises an on-off switch which is positioned within the battery receiving case to minimize damage to the switch. The switch operates by moving the anode of a battery towards and away from a contact to make or break a series circuit between a plurality of batteries located in the battery-receiving chamber. Movement of the anode in an axial direction is effected by axial movement of a protuberance on the switching device.

Abstract: A wireless-controllable toy car with a winch mechanism is disclosed which is provided, in addition to driving wheels and the winch mechanism, with an electric motor for driving and controlling the wheels, another electric motor for controlling the winch mechanism, and a change-over switch for switching a power circuit for the electric motors.

Abstract: A multiple wheeled toy car featuring a remotely controlled front wheel steering and a single powered, middle, rear wheel for propulsion. Two other rear wheels flank the powered wheel. The flank rear wheels are each mounted upon a freely moveable road wheel arm with a limiter to limit upward travel of the arm. These flank wheels contact the surface and tend to resist lateral displacement of the car's rear end when the car has been placed into a hard turn.

Abstract: A direction-converting device for a toy car is disclosed, in which the toy car is provided with an electromagnet having an exciting iron core with its opposite sides being energizable to different polarities and a magnet having opposite end faces with different polarities, in which one core portion of the electromagnet at its free end has a width equal to or larger than a width of the opposed end of the magnet, and in which the electromagnet or the magnet is fixed to one end of a controlling element which in turn is arranged at a middle portion of a steering element. The one core portion of the electromagnet may be divided into two portions, between which is arranged another magnet.Thus, the device ensures a neutral position of the steering element reliably in the deenergized state of the electromagnet.

Abstract: A driving apparatus for use in a movable toy is disclosed, and includes a mobile body, an immobile body, a plurality of permanent magnets fixed to the mobile or immobile body, at least one electromagnet fixed to the other body so as to co-operate with the permanent magnets, a pair of contactless switches, and a circuit for exciting the electromagnet winding depending on the state of energization of the contactless switches and the position of the permanent magnets relative to the electromagnet. The driving apparatus is capable of not only rotary movement but also straight movement.

Abstract: A rechargeable wireless-control toy racer is disclosed which includes a wireless transmitter, a control signal from which is received by a wireless receiver for controlling the toy racer. In accordance with the invention the toy racer contains a battery as a power source and is provided with a recharging connector terminal therefor, and that the wireless transmitter is provided with another recharging connector terminal to be connected to another power source and connectable to the first-said recharging connector terminal.

Abstract: A remote-controllable toy car is disclosed in which a car body is connected to an operating device through a single or a plurality of optical fibers. The toy car may be controlled in a simple optical communication system and is suitable for a small child.

Abstract: A burner apparatus for a smelting furnace comprising a burner body having a tip insertable into and withdrawable from a burner inserting bore in the wall of the furnace, a seal bar insertable into and withdrawable from the bore for closing the bore, shifting means for alternatively positioning the tip or the seal bar in alignment with the bore, and means for driving the tip and the seal bar into and out of the bore. When the burner is not used for auxiliary combustion, the seal bar is inserted into the bore to prevent the bore and the burner nozzles from clogging with splashes of molten metal and slag.

Abstract: A direction converting device for a toy car has an electromagnet energizable to a desired polarity upon change of a running direction and at least a pair of magnet elements arranged oppositely thereto and maintained at different polarities from each other.

Abstract: A water-cooled lid made of steel tubing and removably mountable on the top of the body of an electric furnace comprises a small central top portion having electrode inserting bores, a circular ring along its outer periphery and a plurality of sectorial segments arranged radially between the top portion and the circular ring. Each of the sectorial segments has a zigzag cooling water channel formed by steel tubing, extending along circumferences concentric with the lid and having a cooling water inlet and cooling water outlet. The zigzag channel is formed by bending a single steel tube into zigzag portions folded together in intimate contact with one another. Alternatively the channel is formed by a plurality of steel tubes arranged side by side in intimate contact with one another along circumferences concentric with the lid and steel frames having communicating chambers in communication with the open ends of adjoining tubes.

Abstract: A wireless trans-ceiver control system for a motor driven toy vehicle having a transmitter for generating a predetermined carrier of selected high frequency, and a receiving unit including a super regenerative detection circuit for receiving the high frequency carrier and normally producing an amplifiable noise signal which is attenuated by the high frequency carrier. A relay switch, for reversing the power to the electrical motor driving the toy vehicle, is energized by the amplified noise signal to retain the switch in one position and release the relay to a second position when the high frequency carrier from the transmitter attenuates said noise signal. In a modification, a gearing train drives the vehicle in one direction in one position of the switch but drives the vehicle in the same direction and also turns the wheels for turning the vehicle in the second position of the switch.
