Abstract: Apparatus is provided for adapting an analog depth sounder for the calling out of the depth at regular time intervals. In one embodiment, a self-contained adapter module is mounted to the face of the depth sounder so as to cover the depth sounder display, with the module including a transparent plate carrying a detector array and with electronics and speaker carried at the center of the array. In this embodiment, the detectors are arranged in thin radially extending lines to permit accommodation to displays of different diameter. Alternatively, small detectors are arranged along a circle having a diameter which overlies at least a portion of the orbiting radiating element which radiates along a considerable length. This alternative array configuration also accommodates a range of display diameters. As a further alternative, to accommodate different diameter displays, the thin line detectors may be replaced with radially extending light pipes with detectors at their ends.

Abstract: A wall hanger is disclosed in which a bow tie arrangement having porous end portions is mounted on the back of a picture to be hung on a wall. The bow tie is made to adhere to the back of the picture by the penetration of adhesive through the porous end portions, thereby to give strength to the hanging system. In one embodiment the adhesive is applied through the porous end portion and onto the picture backing, with the adhesive applied separately. In another embodiment, a bow tie type hanger is made of preformed and stretched nylon. In a still further embodiment, the hanger includes two separated pad portions with a flexible member between the pad portions in which the flexible member is offset from the plane of the pads to permit engagement of a hook when the hanger is adhesively attached to the back of a picture.
