Etching negatives e.g for graphic and cartographic purposes, are produced by a chisel (10) moving over and into a lacquer which is applied on circular opaque glass plates (3,4). The plates are rotatably mounted on large ball bearings (12,13) supported on consoles (19,20). The outer cages of the bearings carry cups (11) which support the glass plates. The consoles also support circular fluorescent ...

The present invention relates to a method for fine positioning vehicles in exact relationships to geographic reference markings, whereby the vehicle (1) is adapted to fetch and deliver loads (2) preferably goods carried on loading stools or pallets, at fetching and delivering points (3-14), whereby it is required that the vehicle (1) repeatedly may be brought to exact positions relative to said fe...

A hot tire forming method whereby at least some of the elements constituting each tire are formed starting from respective masterbatches, which are mixed with given chemical compounds inside respective continuous mixers to obtain respective final mixes, which are hot-fed to respective continuous production means, such as extruders, for obtaining semifinished products, which are hot-fed onto a fini...

A tire curing system in which a number of mobile curing units, each designed to house a respective green tire, are selectively and independently fed along a loop circuit having at least two parallel branches, the ends of which branches are connected to a common section extending through a station for loading and unloading tires on and off respective curing units; each curing unit incorporating a m...

A run-flat pneumatic radial tire is equipped with a prestressed helical coil which is positioned inside the tire crown radially inwardly of the tread thereof. The coil is wound to approximately 50 percent of its free diameter to prestress it and the outer surface has a resin-impregnated tape applied thereto. The tape serves to hold the coil in a predetermined condition while the taped coil is cure...

A process for producing a tire reinforcement is characterized by the fact that each reinforcement cord is projected individually into its place in the reinforcement. For this purpose, a machine is used which comprises laying members comprising essentially a rotary conduit which projects the cord by a radially outer extremity of the conduit and rollers which impose a linear speed of laying of the c...

The dissolution rate of water-soluble polymers in water can be precisely controlled. This is accomplished by inverting a water-in-oil emulsion containing the water-soluble vinyl polymer into water which contains at the time of inversion an exact amount of an emulsifier system having an HLB number which has been predetermined to produce a specific solubility rate for the water-soluble vinyl polymer...

Improved coatings on polycarbonate are formed by polymerizing a mixture containing (1) an oligomer or a reactive resin having a molecular weight between 400 and 4,000 and containing at least two acrylic groups per molecule, and (2) an N-vinyl derivative of straight-chain or cyclic secondary amide, the polymerization being carried out in the presence of a photoinitiator.

A process for manufacturing an atomized amalgamable alloy having mold adaptation characteristics superior to other atomized alloys and comparable or better than those for ad-mixed type alloys (alloys which are mixtures of spherical and irregularly shaped particles), and physical properties comparable to ad-mixed alloys. The process includes the steps of: producing a melt of an amalgamable alloy; a...

An actuating device for a vehicle brake rigging, comprising a service brake and a spring parking brake. The device comprises, apart from a service brake cylinder (1) and piston (2) and a parking brake cylinder (15, 17) and piston (12), a ratchet wheel (8) disposed between the two pistons, non-permanent connection means (6, 7) provided between the ratchet wheel and the service brake piston; and fur...

Polyorganosiloxane foams are obtained by blending, dispensing and curing two-part polyorganosiloxane compositions comprising a liquid hydroxyl endblocked polydimethylsiloxane, a liquid alkyl orthosilicate as the curing agent, a catalytically effective amount of a tin compound, a blowing agent and, as a foam stablilizer, a resinous organosiloxane copolymer comprising trimethylsiloxy units, SiO4/2 u...

Solid particles are coated with a uniform and continuous polyamide layer by immersion in a reaction medium capable of forming polyamides by anionic polymerization in solution.

An adhesive composition and a method for its use in bonding rigid PVC elements. The adhesive composition comprises: (1) a first dissolved PVC polymer having a K-value of about 58 +/- and a second dissolved PVC polymer having a K-value of about 45 to about 52; (2) at least one cyclic organic solvent; and (3) at least one non-cyclic organic solvent.
