A process for producing bilayer vesicles from a colloidal solution comprising mixed micelles of a bilayer-forming substance and a detergent, comprises removing the detergent from the micelle-containing colloidal solution by means of flow-through dialysis whereby the colloidal solution is dialyzed against a dialysis liquid in a chamber whose walls are at least partially formed by a semi-permeable m...

According to the method of the invention for removing at least one layer of reinforcing elements (4), such as steel cords, etc. from a breaker or belt (6) located between the tread area (3) and the carcass (5) of a rubber tyre; the tread area of the tyre is first removed down to the layer of reinforcing elements by rasping off this tread area, and afterwards each reinforcing element (4), for examp...

A manually powered winch has two geared drive trains. Both originate from a simple set of gear teeth (7) formed into the diameter of a drive input shaft (5). The final drive, common to both gear trains, to an internal gear track (18) on the drum (3) of the winch is one part (12) of a two-part gear (8,12). The part (12) is directly borne by a hub (20) on an axle (10) in the winch. Its gear teeth ar...

A modified low-density flexible polyurethane foam product having a relatively high degree of firmness as well as commercially acceptable dielectric heat sealing characteristics. The product formulation includes an intermediate constituted by a mixture of polyol and a polymer/polyol in a ratio imparting to the product a predetermined degree of firmness, and a thermoplastic additive whose dielectric...

For the production of wrapped wire rings, especially bead cores for tyre beads, the core ring (8) to be wrapped with a wrapping wire (5) is driven by being periodically and successively grasped at points which move in the circumferential direction of the core ring (8) and are situated in mutually opposite pairs on both sides of the core ring (8) with the aid of a pair of driving discs (11) which a...

A melt-molded film of a wholly aromatic polyester, said film having in its plane two perpendicularly crossing directions in each of which the Young's modulus and strength of the film at 25 DEG C. are at least about 200 kg/mm2 and at least about 5 kg/mm2 respectively, the product of the Young's moduli of the film in the two directions being at least 8x104 (kg/mm2)2, and said wholly aromatic polyes...

In an address-controlled data traffic between a processor (P) and at least one process element (PE), each addressing accepted for the process element (PE) is counted. The result of the count is signalled to the processor (P) so that the latter can compare the number of addressings initiated by it with the number of accepted addressings and thus the correct operation of the data processing device c...

The invention relates to a method for automatic optical testing of glass products, e.g. hollow ware. In such products, annular thick spots (bands) can occur on the wall during production, and have to be rejected. This has been done to date through visual testing by humans. The test object is now arranged between a test pattern and the lens of a camera or another electrical transducer, and the dist...

1462485 Phenoplast resin foams derived from expandable resoles SAINT-GOBAIN INDUSTRIES 20 Feb 1974 [5 March 1974] 7777/74 Headings C3C and C3R [Also in Division B2E] Chemically neutral phenoplast resin foams are made by coating or mixing uniformly a blowing agent on to or with a solid resole-type chemically neutral phenoplast resin in particulate form, which has been made by condensing 1-3À1 moles...

A multilayer film structure is inhibited against the accumulation of static charge on the surfaces thereof by the inclusion in a buried primer layer thereof of a linear high molecular weight water-soluble quaternary ammonium chloride polymer.

The cylinder (10) is vented outwardly in the interior of the diaphragm cylinder by a vent (29) which allows the intrusion of dirt and moisture. The diaphragm cylinder interior is isolated from the guide tube interim (12) by an annular sealing ring or spaced rings (31) seated between the guide tube (12) and the piston rod (14) and sealing the annular chamber (9). The ring is rigidly seated either o...

The non-flammable rigid foam e.g. used as a building material complies with the requirements of DIN 4102 and which provides a non-toxicity of the combustion fumes according to DIN 53436. It has a mass ratio of resin component:filler of at least 1:2,5 and a bulk density amounting to 50 kg/m3 to 450 kg/m3. The resin component is formed by reaction of 50-62 mass parts resolic resin, 0-15 mass parts f...

A method of preparing a foamable polyvinyl system resin composition which renders a non-flammable, high strength to weight ratio foam product comprises, reacting at least 0.05 parts by weight of an organic radical initiator per 1 part by weight of polyvinyl system resin with the components consisting essentially of (a) at least one polyvinyl system resin (b) 2-100 parts by weight of at least one i...

A low density synthetic resin foamed body and a manufacturing method therefore which method is characterized by the steps of filling a mixture of 100 parts by weight of an ethylene-vinyl acetate copolymer, 20-80 parts by weight of a foaming agent, and 1.0-5.0 parts by weight of a crosslinking agent in a mold closing the mold with a lid, heating the mold to form a foamed body, cooling the foamed bo...

A heat shield (50) is positioned on a piston (14) in spaced relation to a friction element (16) to prevent heat transfer directly by conduction. The heat shield (50) opposes a boot seal (24) to keep the latter also spaced from the friction element (16).
