Date Jul. 9, 1981.Metal in the form of granules is solidified from the molten state by forming a jet of molten metal which is caused to pass through a vibrating orifice in order to divide the jet into individual drops and causing solidification of the drops by ...

A process is provided for making a liquid composition of a perfluorinated polymer having sulfonic acid or sulfonate groups in a liquid medium by contacting the polymer with a mixture of 25 to 100% by weight of water and 0 to 75% by weight of a second liquid component such as a lower alcohol, e.g., propanol or methanol, at a temperature of at least 180 DEG C. (at least 240 DEG C. when about 90% t...

Vesiculated polymer beads containing a pigment have in the past been produced employing a process using a polyamine base but this has introduced yellowing of the beads and avoidance of its use is desirable. Accordingly a process has been developed which produces vesiculated polymer beads which have a reduced tendency to be yellow. The new process involves forming an oil phase of the polyester resi...

In a process for the production of a shaped article involving the remelting of a polyamide which has been subjected to a drying stage, such as that which occurs during solid phase polymerisation, the stage of conditioning the polyamide prior to remelting can be reduced or even avoided by adding a controlled amount of water to the polymer when molten or immediately prior to its remelting.

The device makes it possible to optically inscribe and/or read at least two facing sides of disks in an optical memory system, whose disks are stacked. A linear motor displaces a mobile means incorporating recording-reading heads. These heads receive via a bidirectional optical connection data to be inscribed and coming from fixed light emitters-receivers. Each of the recording heads comprises two...

A low-density, low-friability, furfuryl-phenol thermosetting foam product is prepared by reacting, in the presence of a blowing agent and an acid catalyst, a furfuryl-alcohol monomer or polymer and a benzylic-ether phenol-formaldehyde resin, having a mole ratio of benzylic-ether phenol to formaldehyde of from about 1 : 3 to 1 : 11, which reaction provides a closed-cell, thermosetting foam product ...

In order to achieve a non-stick surface which is significantly harder wearing than hitherto, metal surface a is sand or shot blast and stainless steel or molybdenum is applied thereto so as to cover not less than 65% and not more than 90% thereof and provide a pervious intermediate substrate b having a micro-crenellated surface. Thereafter, a primer coat is applied to penetrate pervious layer b an...

1. A process for the treatment of acid waste water containing aluminum and iron, wherein (a) the acid waste containing small amounts of colloidal silicic acid is heated to just below boiling point so as to precipitate aluminum hydroxide and hydrated iron (III) oxide and is neutralized with calcium oxide and/or calcium hydroxide ; (b) the resultant aluminum hydroxide iron (III) hydroxide precipitat...

The magnet frame of a dynamoelectric machine comprises a removable, generally cylindrical inner member concentrically disposed inside a cylindrical outer member. The inner member is supported in a cantilever fashion at only one of its ends, and most of its outside surface is normally separated by a relatively small circumferential gap from the cooperating inside surface of the outer member. The ou...

An article surveillance system employs a label or tag containing a non-linear impedance element, such as a semi-conductor diode, connected to a metal antenna loop configured to pick up two distinct radio frequency transmissions displaced on either side of a selected center frequency. The non-linear impedance element connects opposing sides of a closed loop section at one end of the antenna to form...

A flowable concrete mixture which possesses high strength and which provides facile placement of the mixture in structural forms composed of cement glue and aggregates, the viscosity of the cement glue and volume weight of the aggregates being adjusted so that the aggregates are suspended in the cement glue and remain suspended until the cement glue hardens.

This invention is directed to novel urea derivatives of the general formula (I) wherein A represents one of the groups +TR X and Y, which may be identical to or different from each other, each represent hydrogen, chlorine or bromine; Z represents hydrogen or chlorine; Z' represents chlorine or fluorine; and Z'' represents hydrogen, chlorine, or fluorine.
