Abstract: A car seat is described which includes a panel in the form of a substantially rectangular sheet of plastic material having seat and back portions connected to each other by an integral hinge. The seat and back portions each have a major central area formed with an array of T-shaped elements arranged in columns and rows and each having a T-shaped supporting surface. The T-shaped elements of adjacent rows are staggered and intermeshed to form a lattice of elongate substantially uniform width channels each extending about the periphery of an associated T-shaped section and oriented parallel to one of the directions of the rows and columns. The continuity between the channels aligned along the directions of said rows and channels is repeatedly interrupted by the T-shaped sections. A continuous stiffening bead is provided about each central area to define a peripheral channel open in the direction of the supporting surfaces.

Abstract: A thermoelectric display device is described which includes a thermoelectric element having a surface which exhibits a reversible temperature which is a function of the magnitude and direction of a current passing through the element. The thermoelectric element includes two dissimilar conductors joined in overlapping relation over a predetermined area to form a junction. The junction is advantageously formed by overlapping a p-type semi-conductive layer and an n-type semi-conductive layer, which may or may not be separated in the region of overlap by an electrically conductive layer of material. A cholesteric crystal material is disposed on the surface of the thermoelectric element in the region of the junction thereof in thermally conductive relation therewith, the liquid crystal material being variable between different optical states as a function of the temperature to which the same is exposed.

Abstract: A telephone answering apparatus has a forward drive time delay relay which causes a tape bearing a series of messages to advance for approximately 30 seconds subsequent to the reproduction of the last message in the series. The forward drive time delay relay cooperates with a recording amplifier so as to prevent recording of information on the advanced portion of the tape. The relay also cooperates with an erase circuit to cause recorded information on the advanced portion of tape to be erased to thereby create a no-signal or silent portions of tape. The advanced portions of the tape are detectable by a no-signal detector during rewind of the tape which automatically stops rewind when a no-signal portion is detected. A method is disclosed for generating silent portions on a tape and for automatically stopping rewind in a telephone answering apparatus at points, prior to complete rewind, where the no-signal portions are detected.
