Abstract: A gear drive with a mono-block gear housing with a bottom aperture through which mounts a specially designed oil exclusion pan and bearing oil dams, over which a bottom-mounted access cover seals the housing in normal operation.

Abstract: A high power industrial gear drive with a cooling system that improves upon the designs of shaft fan and electrical fan cooling systems for gear drives by effectively increasing the wetted surface area of the gear drive housing through the introduction of heat exchange tubes through the internal gear drive oil sump and providing cooling surfaces directly in the sump oil for convection from air flow created by the fans through the heat exchange tubes.

Abstract: The disclosure involves a transfer switch having a stationary frame and a front terminal matrix for connection to circuit boards undergoing test. There are two stationary connectors mounted on the switch frame. A platform is supported by the frame for reciprocating movement between first and second positions. Such platform has two movable connectors thereon and when the platform is in the first position, one of the movable connectors engages or “plug-connects” to one of the stationary connectors. When the platform is in the second position, the other movable connector plug-connects to the other stationary connector. The stationary connectors are electrically coupled to respective test devices, e.g., a load board and a signal bus. Thus, the boards under test can be connected to one or the other of the test devices by shifting the position of the platform. A new method is also disclosed.
