Abstract: BINOCULAR INDIRECT OPHTHALMOSCOPE WITH CAMERA               ABSTRACT OF THE DISCLOSURE         An improved portable ophthalmoscope of the binocular indirect type wherein the ophthalmoscope has a camera mounted thereon for photographing the fundus of the eye of a patient when the ophthalmoscope is worn on the head of a clinician.  The ophthalmoscope has an adjustable head assembly providing a support for an observation housing having reflecting surfaces permitting a stereo scopic view of the fundus of the patient's eye.  The camera is mounted at the front of the head assembly near the observation housing and the camera can be actuated with a foot switch or other actuator.  A light source is also carried by the head assembly and has means for directing light into the patient's eye.  Light reflected from the fundus is received in the observation housing. In several embodiments of the invention, the camera is mounted above the observation housing and receives a part of the reflected light from the fundus while the remainder of the reflected light can be simultaneously received for binocular viewing by the clinician.  In another embodiment, the camera is at one side of the observation housing and receives light rays reflected laterally to the one side. Side mirrors in the observation housing permit binocular viewing forwardly of the ophthal-moscope, one of the side mirrors being half-silvered or pivotally mounted in the housing to permit reflected light to enter the camera at the same time as or alternately with binocular viewing of the eye of the patient.

Abstract: A BUILT-IN GROUP DELAY TESTING ARRANGEMENT                 FOR AN FM RADIO SYSTEM by ABRAM FROESE                     LARRY Y. Onotera ALVIN Liebelt Muhammed Jamil Abmed Abstract of Disclosure The baseband input to a frequency modulation transmitter is switchably connectable to a square-wave generator, the amplitude of the square-wave being adjusted to provide a predetermined deviation of the FM radio transmitter.  The output signal of a pilot oscillator is also applied to another input of the transmitter.  This pilot signal is subjected to phase modulation because of group delay which exists in the system and this adversely affects the signal during transmission through the system.          In contrast, the prior art uses commercial test sets which are expensive.  At the receiving end of the radio system, the receiver output includes the pilot signal which has been phase modulated by the group delay slope in the system, because of the square-wave test signal.  This phase modulation is detected in a phase lock loop, prior to being amplified, rectified and applied to a meter so as to provide an indication of the group delay slope in the system.

Abstract: ABSTRACT OF THE DISCLOSURE        A tile perforating unit wherein tile is continuously advanced through a frame by advancing means.  Moveably mounted on the frame and directed toward the tile is at least one perforating tool.  From an initial position, the tool extends and engages a point along the wall of the tile at which perfor-ation is desired.  As the tool moves to maintain engagement with the advancing tile a harpoon is extended from the tool to perforate the tile wall.  Once perforation is completed, the harpoon is withdrawn and the tool retracts and returns to the initial position for repeated perforation of the tile.
