In accordance with the invention, the separator is made of chopped glass fibers having an average diameter of no more than 5.0 microns. The battery is fabricated such that...

Laser irradiation is used to depolymerise surplus encapsulation which is in the form of a thin film extending from an encapsulation of the device. Where the surplus is a thin sheet lying for example over a heatsink or over and between leads the laser irradiation may also vaporise the surplus without damage to underlying parts of the device. Where the surplus is present as a surface layer at an ext...

The invention relates to a sheet feeder for the individual feeding of sheets to a sheet treating machine. A first sheet pile is carried by a main pile table, and sheets from this sheet pile can be fed by a sheet separating device, optionally via a first feed table, to the sheet treating machine. A further sheet pile is carried by an auxiliary pile table. Sheets can be fed by a second sheet separat...

A method and a device for adjusting the X-radiation of an X-ray apparatus, in particular that of a mammographic apparatus, in which the radiation ( PHI 4) having penetrated the photographed object (5) is examined in the beginning of the photography in order to avoid over-exposure of the patient, and on the basis of this the energy spectrum of the radiation is adjusted by regenerative coupling (8, ...

Support for a radiation source (2A) of multiple orientation associated in operation with a radiology table (4) situated transversely to a horizontal axis y-y, comprising : - a radiation source (2A) equipped with movement means (15) and associated in operation with at least one detector (3) for said radiation, - first means permitting a first movement of said support (1) in a plane transverse to...

A compressed air thread splicing device for producing a knot-free thread connection by splicing includes a splicing head having a splicing channel formed therein with two at least partially open ends for receiving threads to be joined in a given insertion direction and for alternately tangling, intertwining, swirling and winding fibers of the threads around each other, the splicing head having at ...

The invention relates to an X-ray tomograph in which the X-ray tube can perform movements which are independent of each other in two directions at right angles to each other. The X-ray tube in a first support can be moved in the transverse direction which is connected to a second support extending in the longitudinal direction which in its main direction is journalled so as to be movable in a stan...

A method for the gaseous reduction of particulate ores to metals in a moving bed, vertical shaft reactor using a reducing gas externally supplied from a solid or liquid fossil fuel gasification unit. The reducing gas is reformed in a reforming zone located within the reactor and treated prior to injection into the reduction zone of the reactor. A portion of the reducing gas produced in a coal gasi...

Halides of Si and Ti, B, P, or Ge and oxygen or steam are introduced into a reaction vessel and heated in a vapor phase to form fine glass particles by oxidation or hydrolysis. The fine glass particles are deposited on a substrate. The deposited fine glass particles are heated and vitrified into a transparent glass layer, which is etched to form a core having a desired pattern by a reactive sputte...

A catalyst system and process are provided for producing polyurethane foams using a carboxylic acid blowing agent, wherein an organic polyol and an organic polyisocyanate are contacted with a catalyst system comprising a dialkylcyclohexylamine and an N-substituted alkoxyalkyl piperazine.

A tire bead assembly of a bead core, apex and gum tie strip is made by laying the gum tie strip about a non-inflatable annular member of triangular cross-section and across the slant surface of the member. The apex is wrapped then about the tie strip and about the slant surface of an annular inflatable bag. After the core is pressed coaxially on the tie strip so as to indent the member and thus pr...
