Abstract: A motorized swing for disabled persons and children which provides pendulous reciprocal movement as well as rotational movement. Electric motors drive mechanisms for inducing reciprocal and rotational movement either separately or in combination. Sensory activated switches are electrically connected to said motors to allow handicapped persons and children to control the movement of said swing.

Abstract: A new method and apparatus for performing a drill stem test in an open (not cased) borehole are disclosed. When the borehole is initially drilled, the drilling process induces a skin damage near the external surface of the open (not cased) wellbore. It is necessary and desirable to bypass, reduce, or eliminate the skin damage in order to provide a free or natural flow of well fluid from the reservoir in the formation into the wellbore. However, in order to determine the degree of skin damage which exists near the external surface of the wellbore, reservoir parameters such as pressures, temperature and flowrates of the formation fluid flowing from the reservoir into the wellbore is first measured in the presence of the skin damage. The skin damage is then bypassed, removed, eliminated, or reduced by, for example, perforating the external surface of the wellbore.
