  • Patent number: 11142350
    Abstract: A drag sail deployment assembly has an enclosure supporting four boom deployment assemblies and four retractable booms. Each boom deployment assembly includes a hub and motor. The hub is configured to hold a wound boom and to rotatably pay out the wound boom. The motor is disposed at least in part within an interior of the hub, and rotates the hub. Each boom is associated with a corresponding one of the four boom deployment assemblies. Each boom includes a plurality of spring elements disposed within a sleeve. Each boom is wound onto the hub of the corresponding boom deployment assembly in a first configuration wherein the spring elements are compressed toward each other. Each boom is configured to expand into a second configuration wherein central portions of the spring elements are spaced apart from each other when the boom is unwound from the hub of the corresponding boom deployment assembly.

  • Patent number: 9556912
    Abstract: An oil deflector is provided comprising a ring-shaped body having a first face and an axial projection extending from the first face. The projection has a radially inwardly facing deflection surface. An oil deflector-bearing assembly includes a bearing, the oil deflector, and a carrier with a plurality of radial oil grooves. The second face of the oil deflector is arranged adjacent to an axial face of the bearing and the carrier is arranged adjacent to the oil deflector so that the projection is at least partially received in one of the oil grooves for deflecting an axial flow of oil.

  • Publication number: 20160238090
    Abstract: A wedge clutch, including: an inner race including first and second sides facing in first and second opposite axial directions, respectively and a radially outermost surface sloping radially inward from the second side to the first side; an outer race located radially outward of the inner race; a wedge plate radially disposed between the inner and outer races and including third and fourth sides facing in the first and second axial directions, respectively, a radially innermost surface sloping radially inward from the fourth side to the third side, and a first plurality of retention features; and an axially displaceable retention ring including a second plurality of retention features. In a free-wheel mode the inner and outer races are rotatable with respect to each other and the second plurality of retention features is engaged with the first plurality of retention features to block radially outward expansion of the wedge plate.

  • Patent number: 4949214
    Abstract: An automatic override circuit is responsive to the magnitude of instantaneous current flow through a monitored conductor to produce an output signal which can actuate a solenoid or a ground fault interrupter to automatically trip a circuit breaker in repsonse to an excursion of current flow which exceeds a predetermined maximum current overhead level. The short circuit protector can automatically override a thermal trip delay and cause the circuit breaker to trip instantly or delay tripping for a prescribed period of short circuit events which exceed the maximum current overload level. In one embodiment, a control signal is generated which actuates a solenoid which is coupled to a thermal magnetic circuit breaker. In an alternative embodiment, the control signal is utilized for automatically triggering a ground fault interrupter.

  • Patent number: 4665304
    Abstract: A heating element for bathroom and similar mirrors is formed as a laminate for placing behind a conventional mirror glass. The laminate has separate foil conductor patterns forming distribution and return conductors for the supply current, and a continuous conductor layer formed by a higher resistivity conducting paint or coating extending between the conductor patterns. Preferably the conductor patterns are formed as longitudinal bands on a continuous web of insulative substrate material which is then cut into lengths which are mounted on backing sheets of appropriate size and which carry buses to establish connection between the conductor bands and an electrical supply.

  • Patent number: 4316187
    Abstract: Method and apparatus for verifying the load rating of an active alternating current distribution circuit at a power outlet. The load rating of the distribution circuit is verified by measuring the change in line voltage at the power outlet as different loads are applied. The no-load line voltage is factored out by summing an analog signal derived from the no-load line voltage with a reference voltage to produce a null balance. When the distribution circuit is loaded by a programmed load or by the load of an external appliance such as a resistance heater, the loaded circuit waveform is transformed and rectified to produce a relatively low amplitude no-load direct current waveform. The transformed, loaded circuit waveform and the null balance waveform are summed, amplified and measured. The amplified sum corresponds exactly with the drop in line voltage across the distribution circuit at the power outlet.
