Abstract: A wrist pin lubricating system for a multi-cylinder two-cycle engine comprises a passage system for collecting and distributing crankcase condensate to the piston wrist pin bearings. A slot in each piston skirt provides continuous communication between each wrist pin bearing and a passage in the cylinder wall delivering condensate from the engine crankcases. The condensate is collected at the low point of each crankcase and is pumped to the wrist pin bearings by the pressure differential between two crankcases. Check valves are provided in the passages to maintain a directional flow of the condensate.

Abstract: This invention provides a woven tubular gasket having a continuous integral attachment means which is contained within the woven tubular members and which has protrusions which extend through or are extendable through the walls of the woven tubular member or members and are adapted to engage openings in an appropriate surface or substrate on which the gasket is to be attached. The method of this invention provides for continuously forming the combination of the attachment means and the woven tubular member. The attachment means is fed continuously into the interior of the woven tubular member as it is formed to thereby incorporate the attachment means into the interior of the woven tubular member.

Abstract: The present invention provides a multiple platen-multiple position press or injection blow molding apparatus for use in the blow molding of containers in which a preform is molded onto a core and is moved relative to the core to space a body portion of the preform from the core when the core is in the blowing station to facilitate the temperature conditioning of the preform to achieve a desired biorientation of the thermoplastic material from which the preform is made when the preform is blow molded to form a container. The temperature conditioning may be achieved by allowing stabilization of the temperature gradient through the material of the preform with or without the assistance of a supply of gas to the preform at a desired temperature.

Abstract: This invention relates to internal combustion burners. In the burners according to the invention, the combustible mixture flows in counter-current to the combustion gases while in contact with the same, and the introduction of the mixture into the combustion chamber is effected along a wall of said chamber and the emitted gases leave the chamber along a second wall thereof, the two walls being opposite one another. The burners according to the invention, which have improved performance and versatility of use, are of use more particularly for mineral fibre drawing processes.

Abstract: A fire-resistant door comprises a core panel of mineral material, such as gypsum wallboard. A fiber mat, preferably comprising glass fibers, is at least partially embedded in each face of said core panel. An edge banding assembly disposed around the periphery of the core panel is centrally grooved to receive the panel edges. Facing sheets are affixed to the opposite sides of the edge banding assembly in spaced parallel relation to the core panel, and a spacer material at least partially fills the spaces between the facing sheets and the core panel.

Abstract: An exterior finishing system for a building. including particularly an exterior insulation system, which includes a fibrous mat-faced gypsum board, preferably a board in which the set gypsum core thereof is water resistant, and preferably one in which the set gypsum core is sandwiched between two sheets of porous glass mat, with the outer surface of at least one of said mats being substantially free of set gypsum, and means for preparing the board, including control of the viscosity of the aqueous gypsum slurry from which the set gypsum core of the board is formed. Also, the use of fibrous mat-faced gypsum board as the shaft liner panel in a shaft wall assembly.

Abstract: The process according to the invention consists of superposing a plurality of panels (1), of providing the pile thus produced with at least one enclosure (2) of shrinkable plastic material, of subjecting the pile to a first compression in a direction normal to its wide surface, of causing the shrinking of the enclosure (2) on the compressed pile to provide a package, of superposing in order of thickness a plurality of identical packages of compressed panels, of applying a flat rigid element (12) against each of the terminal surfaces of the pile of packages thus produced, of subjecting the said pile to a second compression, perpendicular to the flat elements (12) and of joining the pile of packages (5) thus compressed with the aid of assembly means.The invention is applied to the packaging of panels of compressible materials.

Abstract: An acidic aqueous coating composition comprising dissolved phosphate, dissolved aluminum, dissolved dichromate, inorganic colloidal particles and a water miscible organic component including an effective film-forming amount of a water miscible material comprising an ether of a polypropylene glycol, and preferably including also another glycol material, for example, a mono-ethylene glycol material or a mono-propylene glycol material, for use in forming a glaze coating, or a base coating when said composition includes also a particulate material.

Abstract: A wrap-around sleeve, for enclosing and protecting an object such as a wire bundle, comprises a plain weft-knitted sheet formed from a filament having an elastic modulus such that the sheet has a sufficiently high transverse curl force (which is the force with which the sheet tends to curl transversely) that the sleeve remains wrapped around the object without separate closure means. Preferably the elastic modulus of the filament is at least 4000 N.mm.sup.-2.

Abstract: A casket lid and method of manufacture is disclosed. The lid is formed by cutting corrugated fiberboard to form a blank having a central section and end sections, the central section being scored on parallel lines extended longitudinally of the lid, and the central section is flexed on the score lines to provide a domed configuration.

Abstract: Glass fibers for insulation uses are produced by means of a centrifugal spinner which introduces glass streams into an annular attenuating blast adjacent the periphery of the spinner. An improved product quality and/or production rate as well as prolonged spinner life are obtained by selection and utilization of a novel combination of structural and operating parameters characterized in particular by a spinner diameter and peripheral speed substantially greater than conventionally employed.

Abstract: A turf aerator includes a wheel-supported frame and drive means for propelling the frame across the ground at a predetermined rate. A pair of substantially vertical tine arms each having a plurality of downwardly directed turf coring tines attached to the lower end thereof are mounted on the frame for alternate penetrating engagement with the ground. A tine arm actuating mechanism produces an essentially elliptical movement of the upper end of each tine arm, the major axis of the elliptical movement being substantially vertical. A rocker mechanism indirectly connects the lower end of one tine arm with the lower end of the other tine arm such that the horizontal movement of one tine arm with respect to the frame upon engagement of that tine arm with the turf produces an equal and opposite horizontal movement of the other tine arm and vice versa. The aerator produces a substantially vertical insertion and withdrawal movement of the tines and a resultant minimal disturbance of the surrounding turf area.

Abstract: Fiber mats formed by attenuating molten streams of attenuable mineral material by subjecting the streams to the action of a hot attenuating gas blast. The gas blast induces gas from the surrounding atmosphere, and the combined blast and induced gas forming a fiber-carrying current. The current is directed toward a preforated fiber-collecting conveyor on which the fibers are deposited in the form of a mat and the gas of the current passes through the conveyor. Provision is made for withdrawing a peripheral portion of the fiber-carrying current at a point intermediate the zone of attenuation and the perforated fiber-collecting conveyor.
