Dyestuffs of the oxidizable developer-coupler type wherein the developer is a novel 4,7-diaminoindazole of the formula: ##STR1## wherein one of the R's represents C.sub.1-4 alkyl and the other R represents a substitutent selected from the group consisting of C.sub.1-4 alkyl and H (and the water-soluble salts thereof) are very satisfactory for coloring hair. They are readily oxidized by atmospheric oxygen at room temperature without a catalyst, and they provide intense, bright, and fast dyeings in a short time. They are applied in conventional manner from aqueous medium.

Systems, methods, and devices for inelastic gamma-ray logging are provided. In one embodiment, such a method includes emitting neutrons into a subterranean formation from a downhole tool to produce inelastic gamma-rays, detecting a portion of the inelastic gamma-rays that scatter back to the downhole tool to obtain an inelastic gamma-ray signal, and determining a property of the subterranean formation based at least in part on the inelastic gamma-ray signal. The inelastic gamma-ray signal may be substantially free of epithermal and thermal neutron capture background.

Systems, methods, and devices for two-way communication with a downhole tool string are provided. In one example, a method may include placing a downhole tool string into a pressure riser of a well while at least one component of the downhole tool string is not activated. Thereafter, a wireless control signal may be issued through the pressure riser to the downhole tool to cause the downhole tool string to activate the component. The wireless control signal may involve an acoustic signal, an optical signal, and/or an electromagnetic signal such as electrical dipole coupling or magnetic dipole coupling.

Mollusc processing apparatus and related methods are disclosed. Molluscs are held in holders by one of their shells, illustratively the bottom shells, and are moved between a series of processing stations. At a shell cut station, an opening is cut into one or both of the shells of each mollusc. The next processing station includes a cutting blade to cut the adductor muscle and viscera of each mollusc away from its non-held shell, illustratively the top shell, and a shell detach mechanism to detach the non-held shell from the held shell. One or multiple air blasts are directed toward the viscera to loosen it from the held shell, and at a vacuum station the loosened viscera is pulled from the held shell. A second muscle cut station includes another cutting blade to cut the adductor muscle from the held shell.

A method is provided to detect neutrons using a boron-shielded gamma-ray detector, which will detect the 0.48-MeV prompt gamma ray due to the 10B (n,α)7Li reaction. The gamma ray detector can be a proportional gas counter, a scintillation based detector, or a semiconductor detector. Monoenergetic prompt gammas will produce a sharp peak in the pulse height spectrum of a gamma-ray spectroscopy detector. By surrounding a gamma detector with a layer containing 10B, we can measure the gamma signal and neutron signal at the same time and at the same physical location in an instrument. The approach can be used to measure neutron porosity simultaneous with gamma-ray counting or spectroscopy at the same location as long as the 0.48-keV gamma-ray from the neutron reaction does not interfere with the gamma-ray measurement.

The invention concerns a communication system via ACARS messages intended to be placed onboard an aircraft, said system comprising a router (310, 310′) adapted to route said messages from and to a plurality of VHF, HF, SATCOM sub-networks. The system comprises a switch (360, 365) and an AoIP conversion gateway (380), the switch being connected to an HF or SATCOM transceiver module (340, 350) by means of a first two-way link (341, 351), and to said AoIP gateway by means of a second two-way link (381), the switch being adapted to select said first two-way link when it lies in a first switch position and the second two-way link when it lies in a second switch position, the switch lying in the second switch position if the aircraft is on the ground or less than a predetermined distance from the ground, otherwise it lies in the first position.

A fluid pump assembly is disclosed for performing in a damp environment. A pump member is provided that drives a quantity of fluid. A pump housing encloses the pump member and includes a breather hole for circulating cooling air around the pump member during operation. A cover is provided that substantially covers the breather hole and defines a tortuous path that enables air to circulate through the breather hole while preventing entry of water thereto.

A system and method of adding hyperlinked information to a television broadcast in which an interactive content icon is used. The broadcast material is analyzed and one or more regions within a frame are identified. Additional information can be associated with a region, and can be transmitted in encoded form, using timing information to identify the frame with which the information is associated. The system comprising a video source and an encoder that produces a transport stream in communication with the video source, an annotation source, a data packet stream generator that produces encoded annotation data packets in communication with the annotation source and the encoder, and a multiplexer system in communication with the encoder and the data packet stream generator. The encoder provides timestamp information to the data packet stream generator and the data packet stream generator synchronizes annotation data from the annotation source with a video signal from the video source in response to the timestamp information. The multiplexer generates a digital broadcast signal that includes an augmented transport stream from the transport stream and the encoded data packets. A receiver displays the annotation information associated with the video signal in response to a viewer request on a frame by frame basis. A viewer can respond interactively to the material, including performing commercial transactions, by using a backchannel that is provided for interactive communication. The interactive content icon can be used to inform a viewer of the presence of hyperlinked information, for teaching the viewer how to use the system, and for informing the viewer about the hyperlinked information.

摘要:
A weather forecasting umbrella includes a display device in the umbrella's handle that provides a visual indication of the day's weather, such as the probability of precipitation. The display device may take the form of one or more lamps that emit a color, or flash at a varying rate, to indicate forecast weather conditions. The weather forecast that is displayed is preferably obtained using a wireless receiver built into the umbrella that receives data via a wireless paging or cell broadcast network. A display screen may be used to display forecasted information in more detail, including the likelihood of precipitation and/or the forecast high and low temperature for the day.
