Apparatus and method for control of actuator anchor plate release time in spring-biased electromagnetically-actuated positioning systems for gas exchange valves in internal combustion engines in which a ferromagnetic actuator anchor plate is moved back and forth between two actuating solenoids. Pursuant to the invention, the poles of the solenoid core and the anchor plate are separated by a member...

In order to accommodate a relatively large number of paper storage reels (11-17) with diameters of relatively large size in correspondence with a relatively large paper reservoir in a space of relatively small dimensions, storage reels (12-15) are also arranged in side-by-side relationship, i.e. laterally offset with respect to the paper feed slots (21-27) of the printer (20). The path segments of...

A heel-holding device for cross-country and touring skiing boots releases the boot in directions transverse to the longitudinal axis of the ski and in the vertical direction when predetermined release values are exceeded. Through a special design and selection of materials, the number of separated parts of the binding have been minimized.

The invention relates to a process for the production of a flameproofed foam in the form of a foam web. According to the invention, an open-cell foam web having a thickness of 5-50 mm is passed, in the compressed state, into an impregnation bath containing carboxyl-containing latex and zinc salt of a polymetaboric acid and/or aluminium hydroxide and is homogeneously impregnated while being relaxed...

The invention relates to a process for the production of a polyurethane-based foam which does not melt on exposure to an ignition source and which has been impregnated with an organic binder containing solids. According to the invention, the impregnation of the foam is carried out in such an amount that the dry content of the impregnant makes up from 2 to 10% by weight of the unimpregnated foam.

The invention relates to a device for attaching a bag to a body belt, bag strap or the like, there being fastened spaced apart on the back of the bag the two ends of a transversely running carrying strap and, approximately centrally and with spacing below said carrying strap, the one end of a holding strap running transversely to the carrying strap, and the holding strap being passed below the bel...

In the production of a low-flammability polyurethane composite foam which is consolidated from polyurethane foam flakes with admixture of a binder by press moulding at elevated temperature, it is provided according to the invention that, in order to achieve specific calibration of the burning characteristics within wide limits and especially to achieve specific physical values, untreated standard ...

Flame resistant polyurethane foams are prepared by impregnating an open-cell polyurethane foam with a mixture of a carboxyl-containing polychloroprene latex, a zinc salt of a polymetaboric acid and optionally aluminium hydroxide.

This invention describes molded flexible polyurethane foam surfactants which can be used in foam having high concentrations of reinforcing graft copolymer solids.

A two axis rate and linear acceleration detecting multisensor is formed by mounting a pair of accelerometers of the constrained mass type within a case. The accelerometers are mounted orthogonal to each other in vibratory units responsive to an electromagnet therebetween. Rate is determined from the coriolis acceleration force experienced by the accelerometers which vibrate 180 degrees out of phas...

Films (sheets) of aromatic copolyamides of the dicarboxylic acid diamine type whose shaping substance comprises certain recurring structural units and which have specific criteria with respect to Staudinger index, tear strength, volume resistance, dielectric strength, dimensional stability and water absorption capacity are used to produce heat-resistant insulation materials or as substrates for fl...

The object of the present invention are new thermoset resins having quickened curing, a process for their preparation, and their applications. The resins according to the invention consist, at least in part, of the products resulting from the polycondensation of one or more pyridine derivatives containing at least two methyl groups in the 2, 4 or 6 positions, with one or more aromatic dialdehydes,...

This brake actuator has a rod (7) which can be adjusted either hydraulically by means of a piston (9) or mechanically by means of a swivel lever arrangement (26, 27, 29) and the continuation of which, shaped as a ball pin (20), is mounted in a limitedly swivel-movable manner in an axial swivel bearing (17), and as a result permits limited swivelling movements of the rod (7) upon mechanical actuati...

To remove small particles from surfaces of solid bodies at least one laser pulse of high power density (excimer laser) is directed onto the surface. The method is particularly suited to clean Si-masks used in electron-beam lithographic devices. An arrangement for in-situ-cleaning of masks in accordance to this method is integrated in such an electron-beam lithographic device.

The invention relates to a process for the sulphonation of semifinished products or finished parts of polyaryl ether sulphones using gaseous SO3, and to the products produced by this process.

There is provided a porous cellular material comprising a plurality of cavities each defined by a substantially spherical wall formed of a rigid intermeshing matrix of ceramic needles said wall being pierced by at least one aperture to provide access to the cavity, and the or each aperture having a diameter such that the ratio of the diameter of the aperture to the diameter of the cavity into whic...

A film having antistatic properties, and a composition for its manufacture comprise a polyether block amide copolymer and an aromatic sulfonamide antistatic agent. The film can be used for packaging static sensitive devices.

High density polyethylene films, preferably containing blends of HDPE resins or microcrystalline wax, are oriented to a deformation ratio of about 2 in the machine direction and about six or more in the transverse direction to give films having good dead-fold and water vapor transmission characteristics making them highly suited for packaging, particularly for dry foods when coated with or coextru...
