A digital radio receiver generates coherent signals for synchronous detection without use of a phase-locked loop by employing an adaptive notch filter to cancel the desired signal. The cancelling signal is employed as the coherent signal for synchronous detection. The invention obtains faster locking to the desired signal, a wider capture range, and more efficient software coding in a digital sign...

An improved method for detecting small leaks in underground pressurized piping systems is disclosed. In particular, the method comprises the steps of taking pressure measurements over identical time intervals from a product line at a pressure above the pump discharge pressure while the product pump is running. Thereafter, the absolute value of the difference between successive pressure decays is c...

A seismic shut off valve includes a cripple column responsive to seismic movement. A toggle spring overlies the cripple column. Latch pins extend from the toggle spring into a valve body to hold a popper valve in an open position. During an earthquake, the cripple column buckles causing the toggle spring to bow upwardly under spring force exerted on the toggle spring through the latch pins from th...

A fluid pump with a rotary impeller is disclosed which comprises an electromagnetically-driven, bearing-free, seal-free rotary impeller (16) levitated by localized opposed, magnetic forces and by fluid forces, or by localized opposed magnetic forces only. Levitation by localized opposed magnetic forces alone or by a combination of magnetic and fluid forces of an impeller driven by electromagnetic ...

The invention is an absorbent article such as a sanitary napkin, comprising a main body portion which is divided into a first half and a second half by a principle transverse centerline, and an oriented hook fastening material joined to the first half and second half of the main body portion. The oriented hook fastening material is oriented in a direction having a vector component perpendicular to...

An improved process for the copolymerization of ethylene and alpha -olefins utilizing highly dilute alpha -olefin feedstreams to effect high conversions and catalyst productivities. The process is particularly adaptable to copolymerizing the alpha -olefin content of commercially available, diluted refinery feedstreams such as Raffinate-II.

A process and a system for the continuous manufacture of polymeric foams. Reactive chemical components and additives comprising a low boiling blowing agent are mixed under pressure in a mixer (11); the mixture is then frothed before chemical reaction takes place by feeding the mixture through a pressure equalizing and frothing device (13) comprising an elongated pressure-drop zone (17) opening int...

An engineered lighting system for high speed video inspection includes an array of light emitting diodes (10) including light emitting diodes for use in time delay integration (TDI) inspection of web materials (38). The light emitting diodes (10) of the array are selectively controllable to accomplish sequential illumination and carefully controllable imaging of a specified section (42) of a conti...

A banknote selector comprises an aperture (16) obstructed by a rotary shutter (5), the angular position of which is insensitive to the vibrations of the selector. The shutter (5) comprises means for detecting attempts at "string" fraud (13), in which a person attempting fraud introduces a document (20) equipped with strings (13) intended to recover the document (20) once the benefit has been obtai...

The viscosity of bitumen, bitumen-like mixes based on polymer and bitumen and mixes of bitumen and additives is reduced by mixing said bitumen or mixes with at least one gas in a dynamic high shear mixer or in a static mixer.

Polymeric materials, particularly polyethylene (PE) are crosslinked by using a new continuous method based on photo-initiated crosslinking with UV-light. In the method of processing, the polymer, after mixing with suitable crosslinker, photo-initiator, and possible stabilizers, is extruded into a suitable shape whereupon the still warm, soft melt, directly after extrusion ("on line") is crosslinke...

The application discloses a process for making a polymeric powder which is readily dispersible in water to provide a composition useful for forming an enteric coating on pharmaceutical dosage forms and also a process for using the powder for its intended purpose.

Manufacture of a cement-based mixture containing reinforcing fibres and forming a paste by mixing cement and, per 100 parts by weight of cement, approximately 5 parts to approximately 20 parts by weight of a pulverulent first material whose particles have a mean diameter of between 1/5 and 1/10 of the mean diameter of the particles of the said cement, approximately 20 parts to approximately 35 par...

An aqueous sizing for reinforced glass fibers provides improved processing properties, shear strength and compatibility with phenolic resin reinforcers. The coated, reinforced glass fibers are useful in filament winding and pultrusion wherein the coating is an aqueous sizing comprising a ureido-modified amino silane coupling agent and a polyvinyl pyrrolidone film-former. The sizing is free of epic...
