    摘要: A safety barrier comprising a support, a partition frame hingedly connected to the support, and a retractable membrane attached to one end of the partition frame. The partition frame and the support can be extended across an opening, such as a doorway, to securely position the barrier within the opening. The partition frame includes a first member hingedly connected to the support and a second member slidingly engaged to the first member. The retractable member may be deployed toward an opposite end of the partition frame to close off the opening.

    摘要: An array of stabilizing devices for disposition under an object, each device having a base and a central upright, hollow, frusto-conical structure with a retention arm adjustably positioned within the top thereof. The object to be retained is positioned on portions of the bases of the devices, and the retention arm of each device is positioned over a portion of the object, such array to aid in retaining the object in an upright position.

    摘要: A talking book includes front and back panels. A microcassette tape player and logical circuitry with left and right infrared detectors are located at the top of the back panel. A ring binder is located at the left of the back panel adjacent the spline and below the left and right infrared detectors. A housing below the ring binder carries an infrared source that energizes the left and right infrared detectors. The housing also carries a headset jack. A conduit located beside the ring binder accommodates wires between the logical circuitry and the housing.
