A protective glove for protecting hands against cuts, burns, and injury to cold, etching, vibrations, friction and shock. The glove has a palmar hand portion and a palmar thumb portion. A dorsal hand rear portion and a dorsal thumb portion are connected to finger stall portions. Palmar and dorsal finger stall sections are in the form of a single integral piece of material in which the two dorsally extending and longitudinal edges are joined together along the mid-part of the dorsal side of the f...

A drilling jar having a tubular mandrel reciprocally disposed in a tubular housing and extending upwardly from the upper end of the housing. The upper end of the housing includes O-ring fluid seals located between the housing and the mandrel. The upper end of the housing forms an upwardly facing lower impact surface which abuts a downwardly facing upper impact surface around the mandrel. A wiping ring is anchored within the housing and extends upwardly within and beyond the lower impact surface ...

The peristaltic pump has a rotor which is placed around a drive shaft and made up of planet-wheels supported by a planet-wheel carrier. The planet-wheels are maintained in contact with the drive shaft by means of a flexible tube forming a pump body which is passed at least once around the planet-wheels and the suction and discharge ends of which are approximately opposite to each other. Each interval between the planet-wheels is fitted with at least one inner rolling support for the tube.

A method of making a composition useful for making a terpolymer laminate with polyvinyl chloride, polyurethanes and metals. The terpolymer is an alkyl acrylate or alkyl methacrylate where the alkyl group contains 1 to 30 carbon atoms with vinyl nitrile and N,N'-dimethylacrylamide. Improved adhesion is achieved where 1 to 50 parts of organic isocyanate or polyisocyanate is used per 100 parts of terpolymer, where the PVC contains high amounts of plasticizer and with some polyurethanes and metals.

This invention relates to an inexpensive phytase with a low Km value for phytic acid, DNA coding for the phytase, recombinant DNA having the DNA introduced thereinto, a transformant carrying the recombinant DNA, a process for preparing a phytase by use of the transformant, and an animal feed comprising the phytase.

A connector comprising a contact element support 12 and a plurality of contact elements 20, wherein said contact element support 12 comprises a first, e.g. upper surface provided with ribs 16 having walls 26 which define spaces 15 and a second, e.g. lower surface opposite said first surface and provided with recesses 25, and wherein each of said contact elements 20 comprises claws 44 adapted to cooperate with said walls 26 defining said spaces 15 and further comprises a mounting portion 30 adapt...

A toothbrush and replaceable brush head wherein the brush head is easily and positively inserted and removed by axial motion along the axis of the handle. The handle and head have cooperating tongue and groove configurations providing parallel guides to receive and retain the members in assembled relation by virtue of handle recesses and resilient catches on the brush head, while permitting ready disassembly to remove and replace the brush head. Further, the handle and brush head have cooperatin...

cDNAs were synthesized from the mRNA isolated from the mantle epithelial tissue of pearl oyster (Pinctada fucata) using reverse transcriptase and joined to a vector to give a cDNA library. A cDNA inserted in this cDNA library was caused to be expressed in Escherichia coli, for instance, to give a polypeptide corresponding to said cDNA. This polypeptide serves as a novel ingredient of cosmetic compositions, for instance.
