Abstract: A chewing gum stick dispenser includes a generally box-shaped container having a slot therein for dispensing a single stick of gum. A scissoring pair of swing arms utilizes tensioning means for urging the contained sticks of gum toward an operator wall. The operator wall retains a slidable operator having a seat adapted to engage a single stick of gum and push it partially through the dispensing slot. The container further includes a pivoted cap which can be opened to provide easy refilling of the container.

Abstract: A coaxial cable structure incorporating a physical interruption in the outer jacket or sheath of the cable. This interrupts the continuity of the outer conductor and serves to block DC (direct current) and low frequency electrical signals. Also, it greatly reduces heat transmission along the cable. The interruption is achieved by placing a specially fabricated stub in series with the coaxial cable. The resulting coaxial cable assembly acts like a band-pass filter which, although blocking DC and lower frequency electrical signals, is able to transmit RF (radio frequency) signals at selected frequencies. The entire assembly, including the stub, can be made hermetic.

Abstract: Stereo apparatus having angled speakers so as to direct sound at a desired angle relative to the ears of the listener. The disclosed arrangements enhance the stereo sound effect and provide accurate stereo imaging, as well as sound stage expansion, through the proper placement and orientation of speaker units relative to the ears of a listener. The speaker units may be positioned at optimum angles of incidence and distances relative to the ears of a listener. Adjustable positioning means are provided to enable control over the horizontal spatial dimension of the stereo sound. The speaker units may be fixed at a preset orientation, or pivotally mounted for positional adjustment by the listener. Speaker units and releasable mounts may be provided for attachment to eyeglass-style temple pieces for added convenience and comfort. A number of mounting arrangements for simplifying selection of the desired earphone angle are disclosed.
