A techniqu for producing measurements of physical characteristics of subsurface media near a borehole penetrating the earth is disclosed that uses multiple transducers positioned along a borehole tool. A number of transducers of a first type, such as transmitters, are separated from each other along the tool by a preselected separation, and a number of transducers of a second type, such as recei...

The invention relates to a process for producing sacks for bulk material which have, in a side wall in the vicinity of a transverse weld seam, a filling slit extending parallel to said seam as well as a film strip which is arranged in the region of the filling slit, serves as separating means and is welded to the side wall, an anvil being guided in the plastic tube taken off from a reel, thereby l...

An apparatus (1) (Figure 1) serves especially for applying sizing liquor to warp yarns, for example filament yarns. The apparatus, in addition to a liquid tank (5) for sizing liquor (6) and a liquid feed (7) equipped with a pump (8), has a wetting body (4). This wetting body (4) has a liquid-permeable surface (9), on the wetting support of which the warp yarns (3) are guided along. Sizing liquor (...

Highly soluble complexes of 2-(4'-thiazolyl)benzimidazole are prepared using glycolic acid. The aqueous solutions prepared therefrom are stable and may be used for anthelmintic and antifungal purposes. Additional compounds, especially other fungicidal agents, may be combined for compositions of broad spectrum.

The invention relates to an arrangement for the fail-safe periodic testing of electronic devices, for example programmable-memory controllers. The aim of the invention is to increase the safety (reliability) of electronic devices. The invention is based on the object of creating an arrangement which emits a defect signal even in the event of an element of the arrangement failing. According to the ...

The substrate of conventional reagent test devices is replaced by polyester screen material having a nominal filter rating of from about 80 to about 130 microns such that liquid present in the reagent matrix material of the test device is retained therein and prevented from running over onto other reagent matrix areas present on the same reagent test device.

The present invention relates to a process for the preparation of phenol-formaldehyde foams by mixing a resol phase having a viscosity of between 8 and 60 poises and a novolac phase comprising a true novolac, a blowing agent, phenolsulphonic acid and, optionally, phenol, the relative amounts of resol phase and of novolac phase being such that the resol phase represents 45 to 75% by weight of the m...

An apparatus for use particularly in department stores or supermarkets, which apparatus comprises a computer and a storage unit, and is designed as an information and display system. This apparatus allows a user to select desired information stored in the storage unit in a simple and reliable manner. Moreover, direct dialogue between the user and the apparatus is possible. To these ends, a large a...

The present invention provides an additive with a prolonged duration of action for concrete and cement mortar, which additive contains a liquefier and a retardant, wherein the liquefier is an acid group-containing ketone-aldehyde condensation product and/or co-condensation product of at least one ketone and at least one aldehyde.

Arrangement for preventing collision on grinding machines, which arrangement possesses a control for the feed drive and a path-measuring system in the feed axis, using an emergency shutdown device, a tachometer generator and a speed control for the feed drive, in particular for plunge-cut grinding. The aim is to reduce the idle times of the grinding process by fully utilising the maximum possible ...

In a continuously variable transmission apparatus for a vehicle having a slip type clutch disposed between a drive shaft of an engine and an input shaft of a continuously variable transmission mechanism, a torque detecting device to detect torque of the engine, an engine speed detecting device to detect rotational speed of the engine, an output shaft speed detecting device to detect rotational spe...

Disclosed is a water-based thermosetting epoxy composition of a water compatible epoxy resin, about 5 to about 35%, based on a total solids, of a water compatible impact modifier, about 1.5 to about 7%, based on the weight of the epoxy resin, of a water compatible epoxy hardener, up to about 0.3%, based on the weight of the epoxy resin, of a catalyst, and sufficient water to provide a viscosity of...

In order to provide enhanced reliability in the measurement of downhole parameters within a borehole, each downhole parameter is sensed by a pair of detectors 131, 132 and a stream of datapoints representative thereof is generated. Each stream of datapoints is analysed by a processing system 135 relative to the expected statistical norms and physical parameters known to be associated with the char...

Curable fiber resin matrix composites comprising epoxide prepolymers and organic polyamines modified with a heat- and moisture-resistant resin to control flow and tack are disclosed. The cured fiber resin matrix composites exhibit high toughness combined with excellent hot/wet strength.

Orthogonal indicia of orientation of a drilling tool 22 at the end of a drill string 18 within a borehole 12 are measured by a pair of sensors at intervals of a first frequency. Pressure pulses indicative of the tool face angle are generated in the mud flow passing along the drill string 18 by means of a mud flow valve in response to each measurement, and the pressure pulses are sensed at the surf...

Admixture compositions for hydraulic cement compositions are disclosed which comprise a borate ester of a polyhydroxy compound and a hydraulic cement binder. The new admixtures provide increased slump retention in hydraulic cement compositions while causing only a relatively minimal increase in the initial and final setting times of the cement mix. Also disclosed are admixture compositions for hyd...
