Abstract: Non-woven fabrics are produced from oriented foam fibrillated webs contaning 50 to 98 wt. % polypropylene and 2 to 50 wt. % polystyrene. The webs are assembled in a plurality of layers and then bonded by heat and pressure either with or without the presence of an adhesive. In a preferred aspect films especially of polyethylene or ethylenevinyl acetate copolymers are used as the bonding agent.

Abstract: Non-woven fabrics are produced from oriented foam fibrillated webs containing 75 to 98 wt. % polypropylene and 2 to 25 wt. % polyethylene. The webs are assembled in a plurality of layers and then bonded by heat and pressure either with or without the presence of an adhesive.

Abstract: A method for transporting tar sands in an open pit mine utilizing novel flexible belt conveyors between a receiving area and a discharge area which comprises providing a conveyor belt having an upper surface layer of a novel elastomeric material which is flexible at low temperatures and is substantially resistant to excess swelling when exposed to petroleum liquids containing up to 30 volume percent aromatics at temperatures in the range of -60.degree.F to +100.degree.F, applying a thin layer of said petroleum liquid to the surface of said belt and thereafter transferring tar sands on said belt from a receiving area to a discharge area.

Abstract: A laundry oil containing 0.02 to 2.0 weight percent 8-hydroxyquinoline as an antibacterial agent and the process of laundering mops and other fabrics used to wipe dust with such oil. In a preferred aspect of the invention the mops, etc. are laundered directly with the oil. When copper is present in the laundering apparatus the laundry oil preferably contains 0.0001 to 0.5 weight percent benzotriazole.

Abstract: Non-woven fabrics are produced from polyolefin foam fibrillated webs. The webs are treated with corona discharge to improve the adhesion thereof when they are laminated under heat and pressure to form a non-woven fabric.

Abstract: Non-woven fabrics are produced from oriented foam fibrillated webs containing 75 to 98 wt. % polypropylene and 2 to 25 wt. % of an ethylene-vinyl acetate copolymer containing from 2 to 40 wt. % vinyl acetate and 60 to 98 wt. % ethylene. The webs are assembled in a plurality of layers and then bonded by heat and pressure either with or without the presence of an adhesive. In a preferred aspect films especially of polyethylene or ethylene-vinyl acetate copolymers are used as the bonding agent.

Abstract: A laundry oil contains 0.0001 to 0.10 weight percent phenyl mercury oleate as an antibacterial agent. Also disclosed is the process of laundering fabrics used to wipe dust with such an oil and a concentrate for adding to an oil prior to its use as a laundry oil.

Abstract: A method is disclosed for preparing a porous structure of ultra high molecular weight polyethylene. A heterogeneous composite of the polyethylene and a particular hydrocarbon is heated to a temperature above the melting point of the hydrocarbon but below the melting point of the polyethylene. The composite is then shaped. After such shaping the temperature is then raised to a temperature above the melting point of the polyethylene and maintained until complete fusion of the polyethylene particles occurs. Thereafter the hydrocarbon is extracted from the cooled shaped structure.

Abstract: Process of dehydrocyclizing C.sub.6 -C.sub.10 paraffins using a sodium zeolite X or sodium zeolite Y, which zeolite has been ion exchanged with from 0.10 to 1.2 weight percent platinum, the catalyst calcined and the platinum then reduced with hydrogen to the free metal. Said catalyst is characterized by its rather high platinum dispersion. In an especially preferred aspect of the invention, the catalyst is given a final ion exchange with a sodium salt such as sodium bicarbonate. The dehydrocyclization reaction is carried out at from 500.degree. to 560.degree.C and preferably from 510.degree. to 555.degree.C using a partial pressure of hydrogen of from 10 to 300 p.s.i.g. and preferably 50 to 200 p.s.i.g. to form benzene and alkylbenzenes.

Abstract: Disclosed are novel synthetic lubricants containing major amounts of tertiary diamides having the following structural formula: ##EQU1## wherein N = 4-12 ##EQU2## wherein R = H, alkyl radical having C.sub.1 -C.sub.5m = 2-8x = 1-5These lubricants have low pour points and excellent thermal stabilities.

Abstract: Spray oil compositions for controlling post-emergence weeds comprising a non-phytotoxic paraffinic oil and an herbicide selected from the group consisting of cyclohexyl-3-trimethylene-5,6-uracil; 1-n-butyl-3(3,4-dichlorophenyl)-1-methyl urea; 5-amino-4-chloro-2-phenyl pyridazine-3-one; and 3-methoxycarbonyl amino phenyl-n-(3-methyl phenyl)-carbamate.

Abstract: An improved method of transmitting power in a hydraulically operated mechanism which comprises adding to the operative liquid a certain amount of a tertiary diamide having the following structural formula: ##EQU1## wherein ##EQU2## and wherein R R H, alkyl radical having C.sub.1 -C.sub.5m = 2-8x = 1-5The tertiary diamide imparts to the liquid the property of swelling seals in the mechanical system and thereby prevents leakage.

Abstract: An improved crayon wax composition having a wax base, stearic acid, pigment and an additive mixture which comprises polyethylene having a molecular weight between 500,000-6,000,000 is disclosed. Use of the polyethylene in small amounts enables the replacement of higher melting point waxes with low-melting point paraffin wax of 120.degree.-140.degree.F, while still maintaining the required performance qualities of the crayon wax.
