A method of correcting optical exposure masks comprising on a substrate transparent to the exposure radiation used a mask structure not transparent to the exposure radiation used, in which areas to be corrected of the exposure masks are covered with a material not transparent to the exposure radiation used, characterized in that the areas to be corrected of the exposure mask, whilst masking the...

The present invention provides a device and method for protecting, by means of a casing, a measuring instrument or a specialzied tool fixed to the end of a drill string. Said drill string has substantially at is end and before said tool a first guide member and said casing has a second guide member, said first and second guide member being adapted for cooperating together so as to allow movement o...

A sheet product made from a composition comprising 30 to 95% by weight of a polyarylenethioether resin having a substantially linear structure with a melt viscosity of l,000 to 40,000 poise [temperature = 3l0 DEG C, shearing rate = 200 sec<-><1>] and 5 to 70% by weight of a fibrous reinforcing material, which composition is formed substantially into the form of a sheet through the melting state of...

A modified fibrous material useful as a reinforcing matrerial for rubber articles is produced by applying a cold plasma treatment to a fibrous material comprising at least one type of synthetic fibers selected from aromatic polyamide fibers and polyester fibers under a reduced pressure; by applying an ion-plating treatment with a polyamide vapor to the resultant cold plasma-treated fibrous materia...

The invention relates to a process for making woven fabrics, in particular multilayered woven fabrics, on a weaving machine, and proposes to achieve very gentle weft insertion even at a high weft density that the weft densities should be above 20 picks/cm, that the individual picks are initially not beaten up, and that beating up does not take place every time until after insertion of a complete g...

An expandable alkenyl aromatic polymer composition and methods of preparation are provided. The composition is admixed with a volatile blowing agent and an expansion aid which includes a polyphenylene ether. The composition may be extruded and then expanded by exposure to steam or hot air or may be impregnated with blowing agent and then expanded.

The resistance to oxidation of polyolefin thermoplastic foams if improved by the incorporation into such foams of a polyvinyl ether of a C6 - C30 alcohol, preferably polyvinyl octadecyl ether.

A cold-drawn unbalanced biaxially oriented linear low density polyethylene film having a transverse direction draw ratio selected from greater than 1 to less than 3 and a machine direction draw ratio of less than 6 but greater than the transverse direction draw ratio. The film has enhanced tensile and puncture resistance while maintaining acceptable tear properties and is used for shipping sacks.

A fluid bed reactor for treatment of refractory materials with a hot fluidizing gas and a method to use same. Both the refractory materials and the fluidizing gas are introduced from the top of the reactor. Unusually high reaction temperatures of up to 2000 DEG C. are maintained in the reaction chamber due to the presence of heating elements within the reactor and due to countercurrent heat trans...

Die Erfindung betrifft ein Verfahren zum Verkleben von geprägten Polyvinylchloridfolien auf Metallbänder und -blechen, das dadurch gekennzeichnet ist,daß man einen wärmeaktivierbaren, vernetzenden PVC/Metall-Klebstoff zweischichtig aufträgt, wobei die erste Klebstoffschicht auf das Metallband aufgetragen und bei üblichen Temperaturen getrocknet und darauf die zweite Klebstoffschicht aufgebracht un...

A process for improving properties of a synthetic resin powder which comprises: subjecting a latex of a graft-copolymer whose back bone is a rubber to coagulation, and adding a lubricant to the graft-copolymer in an amount of 0.01 to 10 parts by weight based on 100 parts by weight of said graft-copolymer. According to the present invention, the bulk specific gravity of a synthetic resin powder can...

There is provided a process for producing a highly water absorptive polymer, which comprises irradiating ultraviolet rays on a highly water absorptive polymer having carboxylic groups and/or carboxylate groups with its water content being 0.01 to 40 parts by weight per 1 part by weight of said highly water absorptive polymer to obtain a highly water absorptive polymer having a lower content of unp...

Precursor microporous material comprising a matrix consisting essentially of linear ultrahigh molecular weight polyolefin, a large proportion of finely divided water-insoluble siliceous filler, and interconnecting pores is stretched to increase the porosity and provide regions of stretch-induced molecularly oriented polymer in the matrix.

A pump off/gas lock motor controller for electrical submersible pumps (ESP) uses a flow rate or flow/no-flow sensor to shut down the ESP when it no longer is pumping fluid so that damage to the ESP is avoided.

Process for the partial oxidation of fuel using a multi-orifice burner comprising a central channel and three concentric channels encircling the central channel. Fuel is supplied through the second concentric channel at a specific velocity: oxygen is supplied through the other channels at specific mass flow distribution and velocities.

The foams are produced by reacting polyisocyanate and waterglass without use of a blowing agent. Foaming of the reaction mixture is achieved by the CO2, released in the reaction of isocyanate groups with water, in a controlled manner by the addition of a polysiloxane/polyether block copolymer.

The stages of the method which are to be carried out manually are extremely simplified and the degree of utilisation of the blank prior to cutting can be determined objectively and weighed up against the subjective feeling of the suitable selection of the structure. When cutting patterned materials, it is also guaranteed that the pattern on the part to be cut out has been selected in a simple mann...

Porous particles of vinyl resin are disclosed where said particles are non-spherical in shape, highly porous, skinless and friable. Processes are also disclosed for producing these novel particles. The particles are preferably PVC and exhibit an ability to absorb large amounts of plasticizer in a short time.
