The use of a small amount of a polyhydroxy containing anthraquinone compound in a rubber ply or skim stock greatly improves the humid aged adhesion of the rubber stock to brass plated steel cords or fabric. This invention is particularly useful in tires with steel cords or belts. The following formula describes the anthraquinone compound: where two of the R's are hydroxyl radicals and th...

A thin film resistor is fabricated by forming a thin resistive film on an insulating substrate. The resistive film comprises a mixture of silicon nitride and dispersed particles of a metal selected from tungsten, molybdenum and or their silicides. Pref. the thin film is formed by sputtering and has a resistivity between 10 power minus 3 and 10 power 9 ohms/cm. Advantage - the design can be used e....

A process for preparing a crystalline, anhydrous sodium salt of -19-deoxyaglycone dianemycin by precipitation from a dry methylene chloride-hexane solution.

The invention is N-acyl and dihydro-N-acyl analogs of the family of antibacterial and antitumor agents known collectively as the E33288 complex.

The invention relates to the direct detection of human papillomavirus DNA. The recently developed polymerase chain reaction has been modified in order to improve sensitivity and specificity. It is possible, by choosing suitable oligonucleotide primers (amplimers) and reaction temperatures, for individual HPV genes to be identified among the total cell 4 DNA and amplified to such an extent that non...

Internal cells with specified spacing are arranged in rows within an internal cell area where the main logic circuitry is formed. Wiring lines for interconnections are distributed in the spaces between neighbouring cellular arrays. A surrounding bonding pad area for external circuit connections contains a reference voltage supply pad and lies inside an external cell area allotted to cells contg. i...

The fixation element comprises bearing plates 10, 11 which are positioned at a distance axially spaced from each other and which have projecting snap-in members 13, 18 which are intended to engage corresponding openings defined wi...

A button body (10) of an open-faced button includes an ornamental face disk (13) rotatably supported on a cylindrical retainer (14) firmly fitted in the tubular stem (15) of a button back (12). The retainer (14) has an axial hole (33) for receiving the shank (48) of a tack (11), and a radial groove (32) extending transversely across the axial hole (33). The radial groove (32) and the axial hole (3...

Compositions, comprised of a dinitrophenol in an aromatic hydrocarbon solvent, which compositions further comprise a sufficient amount of a phenylenediamine such that a greater amount of dinitrophenol is in solution than would be present in solution if such phenylenediamine were not present, exhibit unexpectedly desirable low temperature stability, and may be diluted with additional solvent to be ...

An installation for the mfr. of an absorbing pad for breast feeding mothers for absorbing surplus milk from the breast incorporates a punching installation for the punching out of discs from a web of absorption material. The discs form the inner layers of the pads and are conveyed by a conveyor. A water-proof paper is connected to a covering material by a joining device after the inner layers have...

Lead is recovered from lead-containing scrap metal in an electrolytic process employing an aqueous solution of C1-4 alkanesulfonic acid as the electrolyte at a high concentration, scrap lead as the anode, and an electroconductive cathode, impressing an electromotive force across the solution between the electrodes to provide a specified steady-state concentration of lead salt in the electrolyte, a...

The present invention relates to a combination of a Savonius type rotor (20) and a deflector plate device (101) which serves as an augmentation apparatus which considerably increases the power output of the Savonius type rotor and also improves its self-starting ability and smoothness of operation. The invention also describes a novel Savonius type rotor (20) of greater efficiency than existing Sa...
