摘要:
A scalper blade assembly for cleaning a conveyor belt. The assembly includes an adjustment structure for adjusting a force applied against the blades for biasing the blades into engagement with the conveyor belt. The adjustment structure includes a ratchet mechanism for incrementally adjusting the biasing force and a clamping structure for maintaining the position of blades and resisting forces applied against the blades from the conveyor. In addition, a blade support assembly is provided for facilitating mounting and replacement of scalper blades. The support assembly includes a support member and a locking member located within the support member, where movement of the locking member relative to the support member is operable to engage and disengage engagement members associated with the blades in locking engagement with the support member.

An ultrasonic flow meter has been adapted for such measurements in the submarine environment. Connected to a collection funnel, the meter houses two piezoelectric transducers mounted at opposite ends of a cylindrical flow tube. By monitoring the perturbations of fluid flow on the propagation of sound waves inside the flow tube, the ultrasonic meter can measure both forward and reverse fluid flows in real time. Laboratory and field calibrations show that the ultrasonic meter can resolve groundwater discharges in both the forward and reverse directions on the order of 0.1 μm/s (

Concepts for conveniently arranging devices for the transduction of signals to and from voltage and current domains to infrared radiation domains is described. Specifically, optoelectronic components and methods of making the same are described. In one aspect, the optoelectronic component includes a base substrate having a pair of angled (or substantially perpendicular) faces with electrical traces extending therebetween. A semiconductor chip assembly is mounted on the first face of the base substrate and a photonic device is mounted on the second face. Both the semiconductor chip assembly and the photonic device are electrically connected to traces on the base substrate. The semiconductor chip assembly is generally arranged to be electrically connected to external devices. The photonic devices are generally arranged to optically communicate with one or more optical fibers. The described structure may be used with a wide variety of photonic devices. In some embodiments the base substrate is formed from a ceramic material having the electrical traces formed thereon. In other implementations the substrate includes a backing block having a flexible printed circuit substrate adhered thereto.

A method of determining the position of a target comprising the steps of: providing a transmitter or a plurality of transmitters to transmit a signal to the target, providing a receiver or a plurality of receivers to receive signals reflected from said target. Determining the time of arrival information of said reflected signal at the or each receiver; using information pertaining to the position of the or each receiver and/or the or each transmitter and with the information obtained determining the target position. Preferably the signal includes a modulated or coded portion unique to the transmitter; and said signal portion is associated with the or each particular transmitter by virtue of said signal portion. The signal maybe a mobile phone transmission, DAB, digital TV, digital Radio or digital satellite transmissions.

A Distributed Object System includes an Event Collection Mechanism (14) which receives information on the creation, deletion and actuation of objects within the system. The Event Collection Mechanism passes on the collected events to an Event Dispatch Mechanism (16) with which user applications may register. The Event Dispatch Mechanism forwards details of events to the User Applications, according to the criteria selected by the user. A method is provided for linking all reported events back to the object which was ultimately responsible for their creation.
