Abstract: A harness supported bag adapted to be carried on the back of a person is adapted for storing a liquid refreshment such as water, fruit juice or the like. A tube extending from the bag to the front of the person enables the latter to draw liquid refreshment during ambulation. In one alternative embodiment, a transparent pocket is superposed over the bag for receiving indicia to identify the person during a race (e.g. a marathon) whereas in another alternatively preferred embodiment, supplementary reservoir means are provided having a passage connected to the bag and manually activatable valve means for selectively enabling a person to transfer the contents of the supplemental reservoir to the bag during running or other physical activity.

Abstract: A new and improved tethered-ball, hitting practice apparatus is disclosed that includes a base member, a vertical support member connected to and supported by the base member, a tether-assembly-retaining member connected to and supported by the vertical support member, and a tether assembly connected to and supported by the tether-assembly-retaining member. The tether assembly includes a tether cord and a spindle for adjusting the tether cord length. The spindle stores and pays out the tether cord and permits a portion of the tether cord to hang freely from the apparatus. A connector is provided to connect the freely hanging tether cord portion to a ball. The tether-assembly-retaining member includes guide elements for guiding a portion of the tether cord from the spindle to the freely hanging tether cord portion. In addition, the tether-assembly-retaining member includes a hollow body portion having an open end and an orifice in a side portion of the hollow body portion.

Abstract: An access security system employs a non-duplicatable key made from an optically transmissive material having gradient refractive index and diffusive properties which provide the material with a non-duplicatable quality. The system provides a high level of security comparable to many biometric systems and is well suited for use in the prevention of unauthorized access to high security areas.
