In a method and device for filtering a suspension of particles in a liquid the liquid is passed continuously through a porous membrane, particles from the suspenion gradually accumulating on the membrane and clogging its pores. The filtered liquid is caused to flow momentarily in the reverse direction to return the accumulated particles to the suspension and so unclog the membrane. To achieve this...

A vulcanization method and press in which at time-spaced intervals of 1 to 40 seconds, temperature measurements representing increments of heat supplied to the vulcanizable body are taken of a medium used for vulcanization. A summation of the measurements continuously during the vulcanization process represents the heat supplied to the body and when the summed heat quantity equals the total heat q...

The etching of dielectric oxide ceramics and dielectric single crystal oxides, particularly perovskite ceramics, is executed by means of laser radiation in an atmosphere having a reducing effect.

A grinding head has at least one expandable grinding tube mounted on an expansion cone. The expansion cone is carried by, and is rotatable with, an expansion rod which is coupled for rotation with a driven part of the head. The expansion rod and cone are movable by means of a ram to cause expansion and contraction of the grinding tube. The connection between the ram and expansion cone via the expa...

A head of a grab for handling gears (robotal devices) for heavy, slightly deformable parts, in particular accumulator lead plates, having engaging levers movable relative to one another, has bearing stirrups (20, 21) receiving the latter non-positively as a stack of parts, with which stirrups are associated in particular pressure plates (29, 30) arranged at right angles to the direction of movemen...

The colour analyser includes a stabilised halogen light source transmitting light via a light guide to a black box having one wall formed by the test surface to be analysed. Light reflected by the test surface is transmitted via a further light guide to a colour analyser comprising a system of filters. - The light guides may be concentric, and the source and analyser may either share a common box,...

Herbicide based on 1-phenyl-4-amino-5-chloro (or 5-bromo-)-pyridazone-(6) in the form of an aqueous suspension containing from 20 to 50 wt % of active ingredient, and silica and a block copolymer of propylene glycol, propylene oxide and ethylene oxide.

Improvements in molded articles from sinterable particulate solids, improvements in method for making such articles, and novel sacrificial binders for use in making such articles are disclosed. The sacrificial binders used in this invention comprise block polymers having the structural formula AB ?AB?n A wherein "n" is 0 or a positive integer, "A" is a linear or branched polymer that is glassy or...

A process is disclosed for converting a bis-(diol) terephthalate to dimethyl terephthalate, by interchange in a methanol medium in the presence of magnesium methylate as catalyst. In this way dimethyl terephthalate may be regenerated from scrap of polyterephthalate or copolyterephthalate filaments or films, for the purpose of manufacturing fresh polyterephthalates or copolyterephthalates which can...

A wholly aromatic copolyester composed mainly of isophthalic acid units and hydroquinone units, the total proportion of said isophthalic acid units and hydroquinone units being at least about 80 mole % based on the entire units, said wholly aromatic copolyester having a terminal carboxyl group concentration, measured by the method described in the specification, of not more than about 90 eq/106 g ...
