A rail pad or other shaped article in the form of a resiliently compressible extrudate having a textured surface and comprising particles or granules of cork or similar resiliently compressible cellular material substantially homogenously dispersed throughout a polymeric matrix of generally saturated thermoplastic synthetic resin, preferably ethylene/vinyl acetate copolymer, which has a stiffness ...

Alkyl aromatic hydrocarbons useful as chemical raw material, solvents and the like are provided in high purity by hydrocracking of a fraction rich in alkyl aromatics and lean in aliphatic hydrocarbons over a particular zeolite catalyst associated with a hydrogenation/dehydrogenation component. The charge stock is characterized by substantial absence of hydrocarbons lighter than benzene. The techni...

PCT No. PCT/SE84/00206 Sec. 371 Date Feb. 8, 1985 Sec. 102(e) Date Feb. 8, 1985 PCT Filed May 30, 1984 PCT Pub. No. WO84/04876 PCT Pub. Date Dec. 20, 1984.The coordinates are determined for arbitrary points on the contour of any body (1). This is achieved by producing a line (13) circumventing the body (1). The circumferential line (13) is moved along the body (1) and is reproduced in various posi...

The catalyst contains components at the following ratio: ferrous oxide 20-75 and chromic oxide 25-80 in % by mass. The catalyst may comprise oxides of cobalt, nickel, manganese, copper, zinc and titanium in an amount of 1,5 to 25 % by mass.

A disposable absorbent structure is provided by an initially molten film, generally extruded, an absorbent unit and fabric. The components are laminated and provide a highly stable, flexible and soft product which contains at least about 5 mls of body exudate per gram.

A sanitary napkin. The sanitary napkin comprises a central absorbent pad and flaps extending from each longitudinal edge of the central absorbent pad. The body of each flap contains a flexible axis about which the flap can fold on itself. The sanitary napkin preferentially bends at the line of juncture between each flap and the longitudinal edge of the central absorbent pad. When the sanitary napk...

The door comprises a leaf (1), provided with a glass pane (3), and a frame (2). The vertical, hinge-side frame spar (5) consists of the light metal profiles (6, 7) which are connected via insulating bars (8). The frame spar is equipped with additional profiles (11) which lie symmetrical to the centre plane (10) of the frame and are anchored in grooves (9) of the light metal profiles (6, 7). These ...

A device for boring tunnels to accommodate electrical cables or conduits in the thickness of an insulative material of a composite wall panel exhibiting a layer of this material covered on one or both sides with a rigid facing sheet made up of a mobile system and a positioning and guiding device for the mobile system. The mobile system incorporates a boring member mounted at the end of a flexible ...

A process for production of infra red reflecting fluorine containing tin oxide coatings on flat glass comprises directing on to a hot glass surface a suspension in a carrier gas of a finely divided solid volatile inorganic tin (IV) compound, free from carbon-tin bonds, containing both chlorine and fluorine. Especially preferred tin compounds are ammonium hexahalostannates of the formula (NH4)2SnH...

Providing a transparent layer of an oxide of an element from group IVa of the Periodic Table, notably TiO2, by providing a substrate with a solution of a compound of the element which upon heating is converted into the relevant oxide, drying the film and heating the dried film so as to form the transparent layer of the oxide. The oxide thus obtained is a form having a comparatively low refractive ...
