Compositions, methods, and systems for manufacturing articles, particularly containers and packaging materials, having a highly inorganically filled matrix. Suitable inorganically filled mixtures are prepared by mixing together an organic polymer binder, water, one or more aggregate materials, fibers, and optional admixtures in the correct proportions in order to form an article which has the desired performance criteria. The inorganically filled mixtures are molded to fashion a portion of the mixture into a form stable shape for the desired article. Once the article has obtained form stability, such as by heating to remove water by evaporation, the article is removed from the mold and allowed to harden to gain strength. The articles may have properties substantially similar to articles presently made from traditional materials like paper, paperboard, polystyrene, plastic, or metal. They have especial utility in the mass production of containers, particularly food and beverage containers.

A molded cementitious architectural product for use in building construction has a cementitious body made of a molded cementitious material, the surface of which is polished (i.e., burnished) to better resemble natural stone. The polished surface is formed by exposing a portion of the molded cementitious material while in a green condition, more particularly after initial set but before final hardening of the hydraulic cement binder, and burnishing the surface before final hardening. Burnishing the surface of the green cementitious material before final hardening aligns the cement particles at the surface and seals the surface. The inclusion of an organic polymer binder within the cementitious material, such as an acrylic or latex polymer, assists in creating a polished surface resembling natural polished stone. The extent of cement hydration may be determined by monitoring the temperature of the cementitious material within the mold. Hydration may be slowed by quenching the molded green cementitious material with water to extend the window of time within which burnishing may be carried out before reaching final hardening.

Apparatuses and methods for removing support material from and/or smoothing surfaces of an additive-manufactured part are disclosed. Apparatuses may include a spraying chamber, a support surface within the spraying chamber, and one or more nozzles having the ability to spray a fluid at the additive-manufactured parts. The fluid may include a liquid and solid particles carried by the liquid. The support surface may have the ability to support the additive manufactured part. The apparatus may include a tank having the ability to hold at least some of the fluid. A heater may be included for heating the fluid to a desired temperature.

A method of reducing the surface roughness of articulating surfaces of orthopaedic implants is provided. The method includes the steps of providing an abrasive particle providing a chemical including at least one of an oxidant, a corrosion inhibitor, a complexing agent and a surfactant, combining the chemical with the abrasive particle to form a slurry, and polishing the implant with the slurry.

A door operator or a door closer having at least one housing and at least one piston supported to be movable in a reception of the housing. The surfaces of the reception and/or of the at least one piston have been treated by exposure to electromagnetic radiation.

The invention provides a rotary wheel bracket clamp holder device and a spinning machining method for a large thin-wall curved face product. The rotary wheel bracket clamp holder device comprises a tool rod, a wheel base and a spinning rolling wheel which is in a three-arc combined shape. The spinning machining method for the large thin-wall curved face product comprises the steps that the periphery of a plate-shaped blank with good ductility is fixed to a tool or a die, the whole is put on a large vertical lathe platform, a spinning device is fixed to a lathe saddle, a lathe programs a curved face circular curve, rapidly spins the blank and carries out feeding machining according to an arc track in a layered circular step-by-step manner, and the blank plastically deforms under the action of the rotary wheel and forms a curved face in an accumulation manner. By means of the rotary wheel bracket clamp holder device and the spinning machining method, the product quality and the production benefits are greatly improved, it is ensured that the fracture phenomenon caused by excessive stretching cannot occur during the stretching process, the surface smoothness degree is kept, and no scratches appear on the surface.

The present invention provides an intake port design that provides a low thermal inertia characteristic, thereby decoupling the surface temperature of the intake port walls from that of the coolant through use of an air gap formed between the intake port and the cylinder head. At idle and part-throttle, the intake port is at a higher surface temperature yielding better cold-start emissions, better mixture preparation, and less dense intake charge (“thermal throttling”) for better fuel economy. At wide-open-throttle, the intake port is at a lower surface temperature yielding better volumetric efficiency for improved torque and reduction in knocking tendency enabling higher compression ratio for improved fuel economy and performance. The intake port design of the present invention can be manufactured with a hydroform manufacturing process resulting in improved dimensional consistency and smooth surface finish. Additionally, the process eliminates some cylinder head machining processes.

A combustible pesticidal product is disclosed which comprises a structural element formed from a pulp of organic fibrous material, cellulose fibres, wood free fibres or mixtures thereof, the product including one or more pesticides which product on combustion emanates the pesticide into the atmosphere. Typically the combustible product will be a mosquito coil which has been impregnated with one or more insecticides effective against mosquitoes. On combustion of the coil, insecticide is emanated into the atmosphere for a period of 7-8 hours.

The surface of a tooling insert is coated with a polymer layer having a low surface energy in order to cover surface irregularities and thereby provide a smooth surface against which a composite part may be compression molded.

The invention is a low center of gravity animal toy. The toy is a scooter type device that includes a cross bar mounted on a pedestal. The cross bar is knurled for extra grip and enables an animal, usually a large bird, to grip the cross bar with their beak and scooter over a surface. Safe and fun interactive and solo play for parrots or other animals is provided.
