An addressable transducer interface which may be associated with a particular electrical transducer, comprises means (107) for storing correction data for the correction of errors as herein defined relating to that transducer so that on addressing of the interface by external control means, the correction data may be transmitted to the control means together with measurement data from the transducer. The storing means is arranged to store said correction data in digital form. The interface inclu...

An interface for interconnecting heat pipes is disclosed. The interface is itself a special purpose heat pipe adapted to efficiently transfer heat from the condenser of a first heat pipe to the evaporator of a second heat pipe. Using the present invention, simple heat pipes can be interconnected to form a complex heat pipe structure for particular applications.

Stabilization of energy sensitive semiconductive devices by forming initial electrodes which are exposed through an overlying layer of semiconductor, dipping the exposed first electrode and the semiconductor layer in colloidal solutions, or well stirred suspensions of specified metal hydroxides, such as those of nickel, chromium, cobalt or related metals, followed by rinsing the non-sensitive side of the device in de-ionized water. After air drying, the deposition of an overlying second electrod...

Interfaces are detected in pipeline batching by means of a capacitance cell for determining dielectric constants. The batch fluid may be purified by a centrifugal filter to allow identification of the batch fluid by dielectric constant.

Stabilization of energy sensitive semiconductor devices by forming initial electrodes which are exposed through an overlying layer of semiconductor, dipping the exposed electrodes in solutions containing specified chemicals, such as metallic ion solutions of nickel, cobalt, chromium and related metals, followed by rinsing, drying, and the final deposition of an overlying electrode by metallization.

The present invention relates to a device for delivering a supply of gases to a patient. The device includes a patient interface and connecting member. The connecting member is preferably a L-shaped swivelled connector that is capable of being fixed into one of two positions, a first position where the connector is freely rotatable within the patient interface, and a second position where an interference between the interface and connector prevents the free rotation of the connector within the p...

Apparatus to detect and/or locate an inhomogeneity in a medium comprises a transducer to transmit frequency-modulated ultrasonic energy through the medium and a transducer to receive reflected energy. The transducers are connected to a phase-locked loop which maintains a required relationship between the phase of the transmitted modulation and the phase of the received modulation by adjustment of the modulation frequency. The modulation frequency adjustment is kept within predetermined upper and...

Provided are a method, system, and program for matching client interfaces with service interfaces. A client component includes at least one client interface and a target component includes at least one service interface. A data structure for the client component associates at least one client interface in the client component with one target component. For each client interface indicated in the data structure, a determination is made as whether there is one service interface in the target compon...

Stabilization of energy sensitive semiconductive devices by forming initial electrodes which are exposed through an overlying layer of semiconductor, dipping the exposed electrodes in solutions containing specified chemicals, such as metallic ion solutions of nickel, cobalt, chromium and related metals, followed by rinsing, drying and the final deposition of an overlying electrode by metallization.

An apparatus for carrying by a diver while underwater that provides information useful for enabling the diver to expeditiously and safely work on submerged vessels without the danger of tapping into an explosive gas. The invention is particularly useful for finding liquid/gas boundary in a submerged vessel or the pressure of liquid or gas behind the wall of a vessel. A transmitting transducer provides a low frequency acoustic tone burst that is transmitted toward the hull of the ship. The reflec...
