Abstract: Multi-reflection effects are reduced by avoiding or eliminating sound reflections from an electro-sound transducer (805). 
     This is achieved by applying acoustic matching layers (802, 804) to front and back surfaces of a piezo-electric element (801) of the transducer (805) to provide phase cancellation of sound waves reflected respectively by surfaces of the layers (802, 804) and the element (801).

IPC: C09K8/02

Abstract: Detergent compositions include water soluble polymers which serve as builders, lime soap dispersants, and antiredeposition agents. The water soluble polymers, which fall into two structural classes, are especially useful in commercial heavy duty liquid detergent compositions, with which they are compatible in effective amounts. The water soluble polymers enhance several detergent properties such as antiredeposition and lime soap dispersancy with a concomittant loss in other detergent composition characteristics. Further, the polymers are compatible with enzyme containing liquid detergents. In the first structural class surfactant radicals are distributed along the polymer chain, which also includes pendent carboxyl and/or carboxylate salt radicals. An example of a polymer within this class is represented by the formula:
     wherein: EO = ethylene oxide  
C 16 -C 18  = a(C 16 -C l8 )alkyl group or an aralkyl or alkaryl group in which the alkyl portion contains 16 to 18 carbon atoms. In the second structural class the polymers are terminated by a surfactant radical. The water soluble polymers are also effective dispersants for a number of particulate materials including kaolin clay and powdered coal, and inhibit the precipitation of calcium chloride and barium sulfate.

Abstract: A system for restructuring an input/output control system having a first (10) and a second (20) input/output controllers each of which respectively connects a first (15) or a second (25) group of peripheral devices in a lower level and a data processing apparatus in an upper level, and controls data transfer operation between each of the corresponding group of peripheral devices and the data processing apparatus, wherein each of the first (15) and second (25) group of peripheral devices is also connected to the input/output controller corresponding to the other group of peripheral devices (25,15) so as to realize a cross call function. Each of the first and second input/output controllers (10,20) respectively holds its own control data, which is used for controlling a data transfer operation between the corresponding peripheral devices (15,25) and the data processing apparatus. When a situation which requires one of the input/output controllers to be in an off-line state arises, that fact is notified to the other input/output controller and the control data held in the one input/output controller is transferred to the other input/output controller. The other input/output controller receives the transferred conrol data and restructures the control data so that the other input/output controller can control the data transfer operation between the data processing apparatus, and all the peripheral devices which were originally under its control 
and all the devices originally under the control of the one input/output controller wherein the above situation has arisen.

IPC: G01V5/10

Abstract: The nature of hydrogenous fluids filling the pore spaces in formations surrounding a well bore are determined by irradiating the formations with bursts of high energy neutrons and using the ratio of time-­dependent parameters related to the decay of epither­mal neutron populations above two different energy levels to provide values indicative of the kind of fluid present, independent of porosity. The measure­ment above the higher of these energy levels, approxi­mately 0.4eV, indicates the existence of hydrogenous fluid, water and hydrocarbons, in the formations; the lower threshold measurement, above approximately 0.15eV, is indicative of the structure of the molecule in which the hydrogen molecule is bound and the porosity. A pulsed neutron generator in a sonde irradiates the formations with 14meV neutrons and a pair of detectors, one shielded by cadmium to establish the 0.4eV threshold energy level and the other, shielded by gadolinium to establish the 0.15eV threshold energy level, respond to epithermal neutron populations created by irradiation to provide count rate information. Time related parameters of the count rate information, e.g. the decay constants, provided by each detector are derived. The ratio of the respective parameters is used to identify the type of fluid in the formation, independent of porosity. The method and apparatus can determine water satura­tion, i.e. percentage of water in the formation fluid and can identify specific types of hydrocarbons under 100% hydrocarbon saturation conditions.
