An electromagnet, and partic. one for hydraulic valves, has a casing which seals off an axially moved armature and the space between terminals, and has a coil magnet. The casing is a magnetic circuit and is held against a terminal block with a non-magnetic spacer ring between them; this ring provides the magnetic gap between the face of the block and the magnetic yoke. The magnet is pref. sealed w...

Expandable rubber for curing tires, and the curing of tires therewith, composed of a specified rubber composition involving butyl rubber with low unsaturation combined with the utilization of stearic acid without castor oil.

Monoclonal antibodies to IFN- beta 2/IL-6 and hybridomas producing them and production and purification of glycosylated and unglycosylated IFN- beta 2/ IL-6 are disclosed. The protein is useful in the treatment of breast cancer, leukemia, infectious diseases and bone marrow progenitor cell disorders.

The separation of organometallic compounds and/or metal carbonyls from their solutions in organic media is effected according to the invention with the aid of semipermeable membranes of an aromatic polyamide.

PURPOSE:To continuously produce the above polarizing film and to obtain excellent polarization performance by continuously supplying a high-polymer soln. contg. dichromatic dyes at a specific ratio onto a water surface and sticking and integrating the resulted thin film onto the surface of a base material at the speed above or below the spontaneous development speed on the water surface. CONSTITUT...

PURPOSE:To obtain a multicolor emission EL device which is stable for a long time by using alkaline earth metal sulfide containing each metal which assumes RGB emission or white light emission. CONSTITUTION:A clear electrode 2 is formed in stripes on a glass substrate 1, and a first insulating layer 3 is formed thereon. Next, an EL emission layer 4 is formed on the first insulating layer 3. The EL...

An apparatus for displaying a travel path of a running body in which a direction detector (2) includes a geomagnetism sensor (21) as well as a rate-type sensor (22), such as a gyroscope or a gas rate sensor for detecting changes in the yawing direction of the moving body. In the apparatus disclosed, a difference angle between the directions detected by the rate-type sensor and the geomagnetism sen...

OPTICAL SHEET INSPECTION SYSTEM An optical inspection system inspects individual sheets having scrolled and unscrolled edges for defects in a production line with high transfer velocities. Each of the individual sheets are delivered in a production line with some spacing between them and potentially with some degree of skewness and offset from the production center line. The inspection system of t...

A hydrocyclone (10) establishes a first vortex (15) of fluent material at one end (e.g. in a top portion 4), and a second vortex at the other end (e.g. in a bottom portion 24). The first vortex is established within a porous surface of revolution (18) to which gas or other fluid is supplied, passing through the porous surface into the first vortex. The second vortex is established by a conical end...

This invention relates to a process for preparing a rigid, closed-celled polyisocyanate-based foam in the presence of water and a blowing agent. The blowing agent comprises one or more organic compounds, particularly halocarbons, having a boiling point of from 222K to 272K at atmospheric pressure, and is substantially free of organic compounds having a boiling point of 273K or greater. Preferred h...

Biaxially stretched, heat shrinkable monolayer and multilayer films comprising very low density polyethylene terpolymers of monomers (a), (b) and (c), where (a) comprises ethylene, (b) comprises a C6-C8 alpha-olefin and (c) comprises 1-butene or 1-hexene, have a very good combination of physical properties and processability including high shrinkage values and puncture resistance.

A process for preparing a permeable sheet of glass fibre reinforced thermoplastic material for moulding into a shaped product which includes binding thereto a surface layer of particulate material which is compatible with or inert to the thermoplastic content of said sheet and which acts to improve the surface finish thereof when the sheet is subsequently heated and chill moulded under pressure.

The process entails forming a droplet of water, cyclodextrin and base in a non-polar solvent such as methylisobutylketone using polyvinyl butyral as an emulsifier. A cross-linking agent such as epichlorohydrin is reacted with the cyclodextrin and emulsifying agent to form the spherical polymer bead.

This invention relates to novel blowing agents comprising a blend of (A) perfluoro- or partially fluorinated-(cyclo)alkanes and (B) one or more of hydrogenated chlorofluorocarbons, hydrogenated fluorocarbons and a low boiling (cyclo)alkane. These blowing agents perform as well as the conventionally used CFC's but are user friendly and do not have the adverse effect of depletion of the ozone layer....

A polyorganosilsesquinoxane fine powder having a moderate hydrophilicity, which is surface-treated with a block- or graft-copolymer comprising a polyoxyalkylene segment and a polysiloxane segment.
