Abstract: An improved microprocessor-controlled sonar depth sounder, which is automatically operative to detect and lock to the bottom of a body of water, fill in the display below the detected bottom, change display scales in response to the detected bottom going off-scale, and reformat the entire display in response to a scale change. A memory is provided for storing target data up to the operable depth limits of the device, thereby allowing display reversing and display expansion or "zoom" of a predetermined portion of the display selected by a zoom cursor. The zoom or cursor is variably positionable at different depths. The device employs an improved variable sensitivity amplifier. Also disclosed is an improved water-resistant switch construction for marine electronic equipment.

Abstract: A caulking spout through which caulk may be dispensed from a dispenser into a corner joint at various angles of attack without an accompanying substantial change in the shape of the bead of caulk being dispensed. The spout comprises a body having a neck elongated along a body axis merging with a rounded tip traversing the axis and an outlet orifice formed in the rounded tip to one side of and off the body axis. An inlet orifice is formed in the end of the elongated neck distal the rounded tip. A channel communicates between the inlet and outlet orifices with a first channel portion extending from the inlet orifice along the body axis and merging with a second channel portion which diverges from the body axis and terminates at the outlet orifice.

Abstract: A method and apparatus for harvesting crops, such as mushrooms, wherein the method comprehends the growing of the crops in rows and the apparatus has a mobile frame adapted for transport along the row; a driven picking assembly mounted on the frame for rotational movement about an axis extending substantially transversely of the frame and having pairs of opposed, radially extending arms mounted thereon for pivotal movement toward and from each other; guides borne by the frame defining first paths of travel for the pairs of arms laterally of a picking station and second paths of travel for the pairs of arms toward each other into juxtaposition in the picking station; a sensing mechanism mounted on the frame adapted to detect crops in the row of predetermined maturity; and a control mechanism borne by the frame interconnecting the sensing mechanism and the guides adapted to direct a pair of opposed arms into the second paths of travel upon detection of a mature drop to pick the crop in the picking station.
