Abstract: A thread cutting mechanism is adapted to be attached by a bracket to a portion of the body of a sewing machine. The mechanism includes a cylindrical hollow tube on the peripheral wall of which the bracket is fixed, along the length of which a guide slot or groove of a given length is formed, and within which a compression spring is inserted. The tube is slidably engaged along its inner wall with an elongated operation rod having both ends projecting outwardly from the corresponding ends of the tube so as to enter into the center of the compression spring and having a pin slidably engaged in the guide slot or groove of the tube and normally pressed against the rear end of the guide slot or groove through the action of the compression spring. The front end of the operation rod is fitted with a cutter for severing a sewing machine thread.

Abstract: In an engine automatic control system for a vehicle for automatically connecting an electric source in the form of a battery with an engine starter and an ignition circuit in response to disengaging operation of a clutch device of the vehicle, for maintaining the ignition circuit conductive while the vehicle runs, and for automatically making the ignition circuit non-conductive when the vehicle is arrested, the engine control system comprises a setting circuit interposed between an ignition switch and the ignition circuit for selectively setting the engine control system to its operative condition and a cancelling circuit coupled with the setting circuit for automatically cancelling the operative condition of the engine control system when the stored voltage of the battery is lowered to or below a predetermined low value.
