A method of manufacture of an abrasive body for use as a wear part, cutting tool insert or the like, includes the steps of providing a mixture comprising an organometallic polymer capable of being pyrolised to produce ceramic particles, and a mass of abrasive particles such as diamond or cubic boron nitride, applying heat to the mixture to cause the polymer to polymerise, and sintering of the pyro...

There is now provided a closed cell rigid polyurethane foam having improved flame resistance by empolying a combination of an organo-phosphorus compound having at least two isocyanate reactive hydrogens with a secondary or tertiary mono-halogenated aliphatic hydrocarbon having three to six carbon atoms.

The core of a piece of a conventional rope is withdrawn and a stiff rod is inserted as a new core (6). The stiff rod (6) may have a dry coating of a thermosetting glue so that the strands (7-9) will be fixed to it when heated. The decorative rod can be used for example as a curtain rod, as a curtain tie-back, or as a hand rail.

A chair mechanism (1) has a seat support (11) and a backrest support (50) which can pivot about pins on a fixed support (2). They are interconnected so that their tilting is synchronised. A lock (30) locks the seat support (11) at a certain tilt position with respect to the fixed support (2) and therefore in turn locks the backrest support. The lock (30) has lock members (36, 37) with ridges or te...

An installation is for removing individual textile tubes (2) from a container (1) through an extraction opening (3) by means of an extractor (4), which rotates round an axis (5) and has grooves for accommodating individual tubes (2). The contours of the extractor (4) vary between the grooves (7) in relation to the extraction opening (3) in accordance with the position of the extractor (4) during i...

Physiologically active caledothricins A-I and their salts, which are useful for the treatment of mycotic diseases. Also strains belonging to the genus Pseudomonas capable of producing the caledothricins upon cultivation.

A gas boiler valve assembly comprises a gas path (3) extending between a gas inlet opening (4) and a gas outlet opening (5) to a burner, adjustably intercepted by a disk (17) operated by respective membrane control means (21). Advantageously, the valve assembly comprises control devices (22, 23) capable of driving in a broad modulation range the membrane control means (21) in response to the air f...

A cutter and transport roller of the type described that is used for webs of materials is particularly well suited as a counter-roller in a machine for winding on continuously supplied webs of film, paper, or similar material. A separating body is installed within the internal space of the roller and together with the periphery of the roller this defines at least one pressure chamber that is conne...

A tissue product and method are disclosed in which individual discrete tissue sheets which overlap each other are wound into a roll. The overlapping provides a means for pop-up, one-at-a-time tissue dispensing. Preferably, the sheets are dispensed axially from a coreless roll. The overlapping sheets within the roll can be interleaved as well as overlapped to increase the frictional engagement betw...

Date Feb. 22, 1996The invention relates to a method for the heat treatment of meat products in a feeding element (4) by means of high-frequency electromagnetic waves, and an apparatus for the execution of the method. The invention also relates to an advantageous ...

This invention pertains to an improved process for preparing chiral or racemic phenylalaninol (PAO) by hydrogenation of L(+)- or racemic 2-amino-1-phenyl-1,3-propanediol (APPD) in the presence of a strong volatile acid. Furthermore, a more valuable form of PAO such like N-blocked PAO was found to be directly produceable from the hydrogenation mixture without isolation of PAO, when a volatile acid ...

Ion selective ceramic membrane with high proton conductivity, which membrane is formed of lanthanide phosphate being doped with one or more metals Me from Group IIA of the Periodic Table and having a composition: Ln1 DIVIDED xMexPO4 wherein Ln is lanthanum, cerium, prasedymium, neodymium, samarium, europium and/or gadolinium; and $$

An ion selective ceramic membrane with high proton conductivity is provided herein. Such membrane is formed of lanthanide phosphate which is doped with at least one metal Me which is selected from Group IIA of the Periodic Table, and which has a composition: Ln1-xMe x PO4, wherein Ln is at least one of lanthanum, cerium, praseodymium, neodymium, samarium, europium or gadolinium; and 0~x~0.5.

A process for activation of metal hydrides is accomplished by incrementally hydriding and dehydriding the metal a plurality of times in a pulsed manner until the desired degree of activation is obtained. Metals useful in the formation of hydrides for applications such as batteries are advantageously activated by hydriding/dehydriding process. This process involves repeatedly stepping the potential...

After the prodn. of the model frame (10, 11), planks (12) are sawn with a contour which permits adjacent planks to be located side by side, connecting to the curvatures determined by the model frame. The sawn planks are softened by heating with steam and are then fitted whilst still warm onto the model frame, being tensioned against it by being bent, so that they conform to the frame curvatures. G...

The two timber components each have an opening (17) passing through at an angle to the longitudinal direction and with a cross-section of an equilateral triangle. Each opening receives in the crossing region the part of the other timber component longitudinal extent which through the presence of the opening has a cross-section of an equilateral triangle.
