Abstract: A valve actuating assembly (10) including an input housing (12) and a circular drive wheel (14) rotatably supported by the input housing (12) and having a cylindrical outer periphery with a plurality of parallel teeth (16). A drive gear (22) is rotatably supported by the input housing (12) and is in meshing engagement with the teeth (16) of the drive wheel (14). The input housing (12) has a first pair of cable guide tubes (24) disposed opposite to one another on opposite sides of the drive gear (22). An output housing (28) is identical to the input housing and supports a driven wheel which is identical to the drive wheel (14). A first conduit (30) is connected to and extends between one of the guide tubes (24) of the input housing (12) and one of the guide tubes of the output housing (28). A second conduit (31) is connected to and extends between the other guide tubes (24) of the input housing (12) and the other guide tube of the output housing (28).

Abstract: A pitot tube assembly for actuating a marine speedometer including an elongated blade member with the pitot tube passage therein and rotatably supported by an integral plastic bracket. The plastic bracket has two spaced support arms with a pin extending therebetween for rotatably supporting the blade member. A pair of spaced slots extend through the bracket between the two support arms to define an integral resilient spring section which is engaged by a cam surface on the blade member. The cam surface on the blade member includes a first flat portion which engages the resilient section to maintain the blade member in the down position and a second portion extending from an apex at the juncture with the first flat portion at an angle so that, when the apex engages the resilient section and passes over center, the second flat portion would engage the resilient section to maintain the blade member in the raised position.

Abstract: A catheter assembly including a plastic tube having a cup-shaped bulb at one end and which is oval in cross section. The walls of the bulb are thicker than the remainder of the tube and a hub is molded about the bulb both interiorly and exteriorly thereof. The bulb is formed by placing the tube on a mandrel, which extends from a mandrel carrier, and thereafter placing the carrier on a base so that the upper end of the tube and mandrel extend through a slot and into a heating cavity defined by a housing. The upper end of the tube is subjected to radiant heat on opposite sides thereof to heat the circumference of the tube unevenly to form and define the cup-shaped bulb. The upper end of the tube is heated to a temperature close to its melting point.
