Abstract: A light device for a bicycle includes a hollow main casing to be attached to a handlebar stem of the bicycle, a first magnet member, a second magnet member having a polarity opposite the first magnet member, a coil member disposed between the first and second magnet members, and a rotary magnet piece disposed adjacent to the first and second magnet members. The first and second magnet members, the coil member and the rotary magnet member are arranged inside the main casing. The rotary magnet member rotates with the front wheel of the bicycle. A light casing is attached to a front open end of the main casing. A light bulb is disposed inside the light casing and is electrically connected to the coil member. The rotation of the rotary magent piece induces electric current in the coil member which powers the light bulb.

Abstract: A liquid pouring device comprises a conduit, a screwed cap, a partition plate, a tension spring, a valve collar and a funnel. The partition plate inserted in the conduit divides the conduit into one long channel and one short channel for the liquid and air to flow. The screwed cap with a gasket is fixed to the top end of the conduit for screwing on the container from which the liquid is to be poured. The stopper is fixed to the lower end of the partition plate and the valve collar is slidably fitted over the small part of the conduit. The tension spring is fitted over the conduit between the valve collar and the flange of the conduit. The funnel is connected with the valve collar. Thus, the liquid can be poured from the liquid container into an empty container smoothly and safely.
