The yarn handling machine employs a bobbin gripper which engages a bobbin positioned at a collection position and moves the bobbin to a transfer location whereat the bobbin is transferred into a cradle mechanism. Both the bobbin gripper and cradle mechanism are moved together to position the bobbin at a winding position. During the latter phase of movement, the bobbin gripper pivots on a carrier a...

Lumps of a mineral or like material comprising two or more solid phases at least one of which is electrically semi-conductive and of different conductivity and permittivity from the other or others are subjected while immersed in water or other high dielectric medium, to the action of an electrical discharge of high enough potential to ionize the mineral. The discharge so generated crushes the lum...

An apparatus and method for assembling battery cell elements having a plurality of electrode plates of alternating polarity separated by a continuous interleaved insulating sheet. The apparatus includes a separator sheet supply station; a creaser for forming transverse creases in a length of separator sheet at longitudinally spaced fold points; a first plate loader for positioning a first set of e...

X-ray apparatus and method for producing discrete images of a human organ in fluctuating motion, e.g., the heart and related vessels. Each image is derived at a selected time related to the cardiac cycle. The images are independently presented on respective discrete areas within a common image plane. A source of X-rays irradiates the organ. A physiological synchronizer produces timing signals with...

1. Process for the production of non-shrinking foams which contain urethane groups by the reaction of compounds with a molecular weight of from 400 to 100,000 which have at least 2 active hydrogen atoms with polyisocyanates in the presence of water and/or organic blowing agents, silicon compounds and optionally in the presence of catalysts and other auxiliary agents, characterised in that the sili...

PURPOSE:To obtain effective gaseous fuel and lumped ashes as resources from solids in a system for using separated and dried sewer sludge and gases for drying, heating and fuel, by supplying part of separated solids to a gasifying device and the rest to a cyclone combustion chamber. CONSTITUTION:The dry sewer sludge and gases separated in a separator 5 are heated to high temp. with a heat exchange...

An installation for vehicles moving automatically, without human intervention, between starting and arrival points along a predetermined path consisting of stops, junctions, crossings, inlets, outlets of elevators, etc. An installation in which each self-propelling vehicle is adapted to carry a load and has steering-wheels and a central driving-wheel as well as optical detectors designed to read a...

Relatively long metal microfilaments made from film forming metal material are described. The microfilaments can be used to make superior high strength structural materials and/or can be used as reinforcing materials in plastic and rubber compositions. The microfilaments are made by forming a liquid film of molten film forming metal material across a coaxial blowing nozzle 5, applying a blowing ga...

The port cap comprises a hollow body member having a wall at its first end, a second end which is open, and a hollow interior. The closed end of the body member carries a hollow projection having a first end which is ...

The application deals primarily with the guidance and positioning of a travelling automatic servicing device (16) relative to a plurality of operating stations (12), e.g. of a spinning machine, which are to be serviced thereby. Aspects of the communication of information between the device and the stations are also dealt with insofar as they are associated with the guidance and positioning feature...

An industrial wastewater treatment method is described whereby heavy metals dissolved in the wastewater are precipitated as a slurry which, when allowed to settle, will form a sludge containing at least 10 weight percent solids. In the method, an aqueous suspension or solution of a neutralizing agent is introduced into a first reactor. A suspension containing particles of carrier agent is also int...

An expandable molding composition for the production of a cross-linked foam material, and a process for the manufacture of the foam from a mixture of polyolefin and a selected, partially crystalline ethylene-propylene terpolymer, a blowing agent, and optionally a crosslinking agent are disclosed.

An improved seal is disclosed for hydraulically sealing a piston-cylinder assembly used in activation of a floating caliper disc brake. The improved seal comprises an annular groove circumscribing the cylinder wall within which a ring type elastomeric seal is seated so as to sealingly engage the piston. The floor of the annular groove has a flat portion and sloped portion. By varying the ratio of ...

A device for continuously measuring the azimuth and slope of a drilling line includes a gyroscope and an accelerometer station disposed in a container suspended from a cable.
