Abstract: Gutter drain apparatus for emplacement in concrete decking includes a drainage trough and a cap member adapted to be detachably retained over the open top of the trough. The device is protected from the inward pressure of expanding concrete by grooves formed on the top of side walls of the trough. The cap member has depending latching members each having an inwardly facing bevel. These are adapted to enter the grooves and to slip past and engage outwardly extending lips provided on the inner side of the grooves to detachably latch the cap member on the trough.

Abstract: A cooling fluid path formed in a calibrating tool body member includes a plurality of parallel openings extending within the body member from one side of the body member. The one side of the body member includes a slot interconnecting the parallel openings. A plate member covers the one side of the body member to close the slot to form a fluid path. A plurality of baffle members, each positioned from the plate member and across the slot and within one of the openings partially along the length of the opening, forms a serpentine fluid path back and forth within each opening on both sides of the baffle and between adjacent openings within the slot.

Abstract: An electrically nonconductive watchcase for use with electronic timepieces is disclosed. By means of an internal plate electricity is conducted from the energy cells to the integrated circuit and display package without the need for utilizing the watchcase as a conductor. A clear latex boot provided over the integrated circuit and display package renders the unit substantially watertight.
