    Abstract: A door-closer hinge includes a first flap secured to a door, a second flap secured to a door frame, and an automatic closer as restored by a restoring spring and having a longitudinal casing secured to the second flap, in which a rotor vane fixed on a rotor having a needle passage formed in the rotor is operatively rotated with respect to a cylinder vane fixed inside a cylinder which is filled with a hydraulic oil and disposed around the rotor to thereby form a rotary-movement shock absorber for quickly opening a door when the oil is rotatably driven to contract the two vanes for quick flow of oil to the left, or for slowly closing the door when the oil is slowly returned to the right to expand the two vanes to allow oil flow merely through the smaller needle passage in the rotor.

    Abstract: A door closing device has an upright tube closed at the bottom and containing a damping liquid, a sinker weight being arranged in the tube and connected to a flexible cord which extends out of the top of the tube for connection to a door so that a door is automatically closed when released, the sinker weight falling under gravity to pull the door closed. The device includes a passage extending through the sinker weight with a valve seat formed at the lower end of the passage and co-operating with a buoyant self-seating valve member (preferably a plastic ball which is not captive relative to the weight) which controls liquid flow through the passage when the weight sinks. As the door is opened, the weight is pulled rapidly upwards and lifts off the buoyant valve member. Preferably, the valve member substantially seals the passage in the weight and there is a clearance around the weight for passage of the damping liquid during closing of the door.

    Abstract: A hood tilt retardation system comprising a shock absorber mounted on the side of upstanding member near the motor truck engine provides cushioning of the hood descent into its fully open or closed positions in the final segments thereof. This cushioning is augmented by a pair of springs attached to the hood and upstanding member for movement thereabout and functioning as a counterbalance to the hood weight during the hood reciprocal movement between its open and closed positions.

    Abstract: A door closing device which is easily mounted on, and easily removed from, an offset pivot hinge. The door closing device has an outer sleeve, an inner member rotatably mounted in the outer sleeve and a coil spring having opposite ends thereof connected to the outer sleeve and the inner member, respectively. The door closing device is mounted on, and operatively connected to, the pivot hinge by non-rotatably fitting the inner member and the outer sleeve with a pivot pin of the pivot hinge and a hinge plate pivoted on the pivot pin, respectively .The door closing device is provided with a door closing speed damping mechanism, a door stopper mechanism, and/or a preset mechanism for the door closing torque, which are assembled within the outer sleeve.
