A method for the manufacture of very low density mineral wool structural panels on a moving foraminous support wire (40) by frothing a dilute aqueous dispersion of mineral wool. The froth, a mass of delicate, non-resilient and non-uniform bubbles among the entangled mineral wool fibers readily breaks, is stripped of water and dried without substantial loss of the highly open, porous structural con...

A cementitious composite material exhibiting a unique combination of high strength, vacuum integrity and thermal properties. Objects made of the material may be cast from mixtures in which a major constituent is a filler which consists of stainless steel particles of particular shapes and sizes. The cast objects are characterized by the absence of a continuous network of interconnected pores and b...

A method for closing the opening of each of the through-holes formed in the pipe-wall of a resin pipe and extending parallel to the axis of said pipe, comprises pressing one end portion of said pipe in the direction parallel to said axis in a mold for closing said opening, said mold being connected to a high frequency current source, and heating said end portion by applying a high frequency curren...

A polycrystalline diamond tool comprising a diamond layer (A) is bonded to a support body (B) having a complex, non-plane geometry by means of a thin more than 3 mu m continuous layer (C) of a refractory material applied by PVD or CVD technique.

To prevent the formation of ghosts as sheets are pulled off a delivery drum (1) by a transport chain arrangement, the gripper mechanism (3-6) on the chain transport is movably located thereon to impart forward movement to the gripped sheet in addition to the movement of the chain and so that tension on the sheet is continuously maintained. The mechanism for imparting said additional movement inclu...

The connection of the facing ends of a tubular bone cut by an operation consists of a cylindrical metal pin with an open-cell metallic outer layer on a cylindrical metal core and with annular grooves for receiving stop surfaces which come to bear against the bone ends. The stop surfaces are suitably formed as flat interrupted rings of circumference slightly greater than half the circumference of t...

A concentrated, liquid, water-soluble softening composition for textiles contains: a) from 10 to 50 % by weight of at least one softening agent A chosen from the quaternary ammonium salts having at least two long C8-C22 alkyl chains, if necessary interrupted by an ester, ether, or amide group; imidazolinium salts; and the reaction products of fatty acids with polyamines chosen from the group of hy...

The invention relates to a medicament injection device in which the material to be injected can be distributed through injection points over a large area surface, whereby simultaneously the device can be easily secured at the injection points and can lie relatively flush with the body without taking up a great deal of space. A mounting support is provided on which several cannulae are held spaced ...

Die Erfindung besteht in einer Lagerung von Kunststoff-Formteilen (5) auf einem Implantat-Grundkörper (1) in der Weise, dass eine mit Spiel gelagerte Abstützung (8) und elastisch verformbare Vorsprünge (11) der Formteile (5) die einander zugewandten Oberflächen der beiden Elemente (1, 5) im Abstand voneinander halten. Dadurch ergibt sich eine elastisch verschiebbare "schwimmende" Lagerung der Form...

A computer memory management method for cache memory (10) uses a deconfirmation technique to provide a simple sequential prefetching algorithm. Access sequentiality is predicted based on simple histories. Each memory line in cache memory is associated with a bit in an S-vector (20), which is called the S-bit for the line. When the S-bit is on, sequentiality is predicted meaning that the sequential...

In a two-level hierarchical system for connected speech recognition, wherein the lower level consists of one or more processing units, the circuit (RIPAC) according to the present invention constitutes one of the aforementioned units, which also provides for performing an additional internal test function. The structure features two internal data buses (BUSIN, BUSOUT) and internal memories for mor...

Selbstschließender Kraftstoffbehälterverschluß (4) zur Befestigung auf einem Kraftstoffeinfüllstutzen (1), mit einer in Richtung auf einen Dichtsitz (8) vorgespannten, in Richtung auf das Innere des Einfüllstutzens verschwenkbaren Verschlußklappe (9) die von einem endseitig gelagerten Schwenkarm (13) getragen ist. Um eine kleine Bauweise und eine degressive Drehmomentcharakteristik beim Öffnen der...

Disclosed are improved ceramic compositions which are useful in the formulation of microwave susceptors and susceptor articles fabricated therefrom for disposable packages for the microwave heating of food items. The compositions include a novel microwave absorbing material and a binder. The novel microwave absorbing materials comprise selected ceramics in both their native and amphoteric forms. S...

In a master-slave multiprocessor (FIG. 1), a slave processor (110) includes a random access memory array (119) that serves at initialization time as the slave processor's boot memory and that serves during normal operation time as the slave processor's cache memory. A master processor (120) writes the slave processor's boot program into the memory array when the memory array is to serve as the boo...

A first line of cellular defense against many viruses, including those causing AIDS, is activation of an intracellular biochemical system termed the 2'-5' oligoadenylate/RNase L pathway. It is well known that this pathway malfunctions in individuals with progressive AIDs-related immune dysfunction, but the mechanism of malfunction remained obscure. An inhibitor substance, released in HIV infected ...
