Appl. No.:

8/112751

Inventors:

Michael L. Dougherty - Sanford FL
Norman E. Warner - Winter Springs FL

Assignee:

S&H Fabricating and Engineering, Inc. - Sanford FL

International Classification:

F16L 13007
F16L 3320

US Classification:

285 39

Abstract:

A tube coupling comprising a metal tube of relatively uniform thickness and having a radially outwardly expanded integral sleeve at one end thereof, and a radially extending tube shoulder being defined at the juncture at which the sleeve is expanded outwardly, the tube having a throughbore of a first inner diameter, and the expanded sleeve having a throughbore of a second inner diameter greater than the first inner diameter and concentric therewith. A cylindrical, hollow insert is located concentric with the axis of the tube, the insert including a radially extending annular collar at one end thereof. The collar has a tube end face abutting the radial tube shoulder and inertially welded to the tube at the interface of the tube end face and the radial tube shoulder. The insert includes at its other end a cylindrical barrel portion having hose locking and sealing means. A flexible hose is supported on the insert barrel portion and secured and sealed relative to the sleeve and the insert by the sleeve being crimped over the insert barrel portion to thereby extrude the hose into the sealing and locking grooves permanently holding the hose in compression.

Assignee:

S&H Fabricating and Engineering, Inc. - Sanford FL

International Classification:

F16L 3320

US Classification:

285256

Abstract:

A hose coupling comprising a metal tube and a cylindrical insert concentrically arranged and held fast within the tube. The tube includes a radially outwardly flared sleeve integral with the tube and providing a tube end and a stop shoulder at the juncture at which said sleeve is flared outwardly. The insert includes (i) a barrel portion extending substantially the full length of the insert and (ii) a radially outwardly flared integral collar at one end of the barrel portion. The collar has an end face abutting the tube stop shoulder, an opposed hose end face, and a tapered circumferential land engaging the sleeve and extending axially at an outwardly diverging uniform taper from the tube end face to the hose end face. The sleeve is preformed to include a circumferential seat portion for seating the collar with the seat portion diverging outwardly at a uniform taper equal to that of the collar and beginning at the tube stop shoulder and continuing to a point at least equal to the length of said collar. A flexible hose is held within the sleeve and supported on the insert barrel portion and abutting the hose end face of the collar.

International Classification:

B64D 41/00
B60R 16/03
F01D 15/10

Abstract:

In some examples, a system includes a load configured to generate propulsion based on power received from a bus via a power converter. The system also includes a controller configured to determine that a voltage magnitude on the bus is not less than a threshold level in a first instance and cause the power converter to deliver a first magnitude of power to the load in response to determining that the voltage magnitude is not less than the threshold level in the first instance. The controller is also configured to determine that the voltage magnitude on the bus is less than the threshold level in a second instance and cause the power converter to deliver a second magnitude of power to the load in response to determining that the voltage magnitude is less than the threshold level in the second instance, the second magnitude being less than the first magnitude.

B64D 27/24

Abstract:

In some examples, a system includes a bus and a first power converter connected to the bus. The system also includes a second power converter connected to the bus, the second power converter having a topology different from the topology of the first power converter. The system further includes a power source and an energy storage device connected to the bus via the first and second power converters, respectively. In addition, the system includes a source controller configured to control the first power converter and a storage controller configured to control the second power converter. The system also includes a system controller configured to determine a first set point for the first power converter, transmit an indication of the first set point to the source controller, determine a second set point for the second power converter, and transmit an indication of the second set point to the storage controller.
