An acoustic method and apparatus for investigating an earth formation penetrated by a borehole are described. Acoustic transducers are mounted on a tool to accurately determine the distance between a segment of the tool and the wall of the borehole. The acoustic transducers are positioned in such manner that the stand-off distance between individual resistivity measuring electrodes in an array, wh...

A light weight lead-acid battery (30) having a positive terminal (36) and a negative terminal (34) and including one or more cells or grid stacks having a plurality of vertically stacked conductive monoplates (10, 20) with positive active material and negative active material deposited on alternating plates in the cell or grid stack. Electrolyte layers (26, 28) positioned between each monoplate ar...

Water and air brake of known type for zero-loss transforming of the mechanical energy of a wind turbine into heat being usable for e.g. room heating or grain drying. The heat is taken from the brake in the form of heated water/liquid or air in dependency of it being a liquid or air brake. These brakes can be provided with an overbraking system of a known principle for the prevention of wind turbin...

A method and apparatus for forming a palletless package having a plurality of layers of objects, the bottom layer of which is formed with cavities to receive the fork arms of a lift truck. A stack of the objects to be packaged is first formed in a palleting device by placing the objects in a plurality of layers each having the same base area. Then, an additional layer of objects is placed on top o...

1330599 Electro-chemical analysis BOEHRINGER MANNHEIM GmbH 16 June 1972 [18 June 1971] 28230/72 Heading G1N The invention relates to a process for the quantative determination of substances by catalysis by an enzyme in an oxygen containing solution and measuring the variation of oxygen content electro-chemically. An air-bubble-free "block" of sample solution is introduced into a stream of buffer s...

An electrically releasable safety ski binding in which a measuring system determines the load applied to a skier's leg during skiing and a release mechanism incorporating an electromechanical converter such as a solenoid acts on a clamp device securing the ski boot to the binding to release the ski boot when the aforementioned load reaches a dangerous level. To prevent the binding becoming inopera...

A heel holder includes a sole holder which is supported for pivotal movement about a horizontal axis on a support member and has a control surface. A locking lever pivotally supported on the support member has a nose engageable with the sole holder control surface. A spring housing having a release spring therein is pivotal about the sole holder pivot axis, and a slide member movably supported in ...

A heel holder includes a base plate mountable on the ski, a sole holder supported for vertical and transverse horizontal movement relative to the base plate, a first locking mechanism for yieldably resisting upward movement of the sole holder away from a closed position adjacent the base plate, and a second locking mechanism which prevents transverse horizontal movement of the sole holder until it...

This invention relates to an improvement of the adhesion of brass-coated steel tire cord to a vulcanized rubber composition. The adhesion is obtained by adding an aromatic triazole and an organo cobalt compound to an unvulcanized rubber compound in order to obtain metal-rubber bonding when vulcanized. Tires formed by the above process have good resistance to heat and moisture.

Disclosed is a packaging material suitable for manufacturing synthetic sausage casings, comprised of a cellulose hydrate base layer, an optional adhesive layer and a layer of a vinylidene chloride-containing copolymer, as well as several methods for preparing the packaging material and sausage casings therefrom.

A masonry cement is prepared by dry mixing portland cement, diatomaceous earth and a water-swellable colloidal clay, such as bentonite. Accordingly, the crushed limestone and other ingredients previously included in masonry cements for admixture with portland cement can be completely eliminated and substituted by diatomacious earth and water-swellable colloidal clay. In this manner, a combination ...

The two-component cement system of the invention comprises a first component which contains 100 parts by weight of a cement and 0.13 to 10 parts by weight, based on the solids content, of an active agent which reduces the amount of water and is based on a polyalkylarylsulfonic acid, selected from the group of naphthalenesulfonic acid/formaldehyde condensation products, anthracenesulfonic acid/form...

PURPOSE:To realize reduction in cost by forming electrode of the three-layered structure on a compound semiconductor substrate where the ohmic contact metal, barrier metal and aluminium are sequentially stacked. CONSTITUTION:An n type growth layer 12 and a p type growth layer 13 are sequentially formed on the GaP n type compound semiconductor substrate 11, an AuGe film is formed on the rear side, ...

The subject invention is a foamable composition based on a blend of a carbon monoxide- or sulfur dioxide-containing ethylene copolymer and a vinyl or vinylidene halide polymer, and the closed-cell foamed article produced therefrom.
