Abstract: A method for extracting oil material from bran includes a filter member having a number of orifices, for supporting bran or husk or chaff of grains. One or more burned elements are then disposed on top of the bran, to burn the bran, and to heat the oil material of the bran to fluid status, and then to collect the oil material in a receptacle. One or more further filter members may further be disposed between the bran and the receptacle. The oil material may further be heated before the oil material is packaged for marketing purposes.

Abstract: A telescopic lock device is used for locking a steering wheel in an automobile and includes an elongated tubular lock body, a central rod secured coaxially in the lock body, and a telescopic tube slidable axially between the lock body and the central rod. When a key is inserted into the key driven unit of the lock body, the rotation of the key can move a movable element into the central bore of the lock body to engage in a selected one of a row of axially aligned notches in the telescopic tube so as to lock the telescopic tube on the lock body. Each of the lock body and the telescopic tube has a forked paw portion which rides on the rim of the steering wheel so as to retain the telescopic lock device on the steering wheel.
