A method for feeding a dosed mixture of splicing air and liquid into a splicing chamber of a compressed-air splicing device, including a valve movable from a receiving to an operating position upon receiving a splicing signal, the valve having a dosing chamber determining the quanity of splicing liquid by the volume thereof, and a mixing chamber, and an element containing a liquid supply, includes...

Splicing head operated by a compressed gas for use in an automatic splicing device for producing by splicing a thread connection without knots, having a splicing head with at least two openings to admit the compressed gas, which accepts the two threads which are to be joined together, and has the capability to effect the mutual tangling, interwining, mixing and/or winding around of the fibers of t...

In fan-beam computed tomography apparatus, timing reference pulses, normally occurring at intervals t, for data transfer and reset of the many integrators (approx. 500) in the signal path from the detector array 10, are generated from the scan displacement, e.g. using a graticule 19 and optical sensor 20, to relate the measurement paths geometrically to the body section 1. Sometimes, a slow scan r...

Method of assessing the effect of periodic inversions of current polarity in electrochemical processes. The method comprises the reading and recording of the variation of the shape and magnitude of the current, the variation of the voltage, the variation of the active internal resistance, and the variation of the electrode potentials during the forward and inverse current intervals and during the ...

Polyesters are combined with UV-stabilizing substances in order to produce an end product, such as a film, sheet, ribbon or filament, by mixing polyester granules and the UV-stabilizing substance in powdered form at an elevated temperature such that at least the exterior surface of the polyester granules is soft, thereby to cause the powdered UV-stabilizing substance to adhere to the individual po...

A flexible polyurethane foam for sound insulation purposes has viscoelastic properties in the temperature range of - 20 to + 80 DEG C and a loss factor of at least 0.3, in the case of a density of less than 90 kg/m<3> and a modulus of elasticity of less than 10<6>N/m<2>.

Stable crosslinked polyurethane aqueous emulsions are prepared by (1) forming in an inert solvent a branched prepolymer derived from (a) an amine containing alcohol having two or three -OH groups, (b) a hydrophobic polymeric diol or triol, (c) a mixture of an aliphatic and an aromatic polyisocyanate and (d) optionally a urethane-forming catalyst; (2) admixing the reaction product ...

An automatic guided vehicle travels for a predetermined distance by detecting the distance covered, and thereafter stops when the mark located at the desired stopping point is detected by at least one sensor. Obstacles on the route, and cumulative error therefore have very little influence on the vehicle's travel, so that accurate travel control is obtained.
