Abstract: The invention relates to a hot asphalt recycling system for adding any used and then ripped asphalt from its original place into new asphalt production, having a heat-insulated frame with a closed volume; at least one RAP material transmission channel within frame, transmission channel being embodied so as to produce a geometrical shape with at least three edges; a transmission line displacing within the RAP material transmission channel and comprising a plurality of transmission plates positioned thereon at certain intervals; optionally a feeding mechanism feeding RAP material to transmission line at a certain speed; an accumulation reservoir formed within frame to store the RAP material heated to a certain temperature without causing any temperature fall; optionally a discharge mechanism providing the transfer of accumulated hot RAP material; and optionally a discharge unit to discharge the RAP material within the transmission line to the exterior when it becomes necessary.

Abstract: A flame used to heat a process material may be extended or otherwise shaped by the application of voltages using electrodes.

Abstract: An abdominal exercise device has an elongated body with a first seating end having a tailbone pad mounted thereon, adjacent a raised second lumbar support end. The lumbar support end has a multi-curved upper surface, including a concave portion between raised side rails that conforms to the lumbar region of a person's body to allow the person to achieve a better, more comfortable workout, with accelerated and improved results.

Abstract: A sheet of a cross-linkable and foamable polyolefin resin is thermally treated on an endless conveyor belt formed of a plain weave wire net. A plurality of parallel, spaced apart rolls are disposed in a direction perpendicular to the direction in which the conveyor belt runs for supporting engagement and rolling contact with the conveyor belt to maintain the flatness of the conveyor belt.

Abstract: A conveyor is driven in a helical endless fashion within a horizontally annular baking chamber while carrying products to be baked. The air within the chamber is heated by means of burners disposed beneath the conveyor and in non-parallel relationship thereto. Heated air is drawn through an air permeable cover across the top of the chamber and into an upper air space thereabove. The air is circulated from that upper air space to a lower air space located beneath the chamber. The air is then circulated into the chamber through an air permeable floor disposed across the bottom of the chamber. The permeability of the cover and floor varies in order to assure a uniform passage of heated air therethrough.

Abstract: The present invention is an oven and method of operation for heating thermoplastic articles. Articles are fed into the oven on a conveyor belt. There is a heating plate directly beneath the article bearing surface of the conveyor belt which heats the supported side of the article. The surface of the article not in contact with the belt is heated by conventional means within the oven.

Abstract: An endless belt (1) transports supports (6) on which electronic components have been placed. The supports have a layer of solder which is to be melted to make electrical contact with the components assembled thereon. A hot plate (8) is arranged at the downstream end of the belt (1). In order to ensure uniform heating of the supports through the belt, the hot plate is provided with openings (10) in its plane, belt-contacting surface. The openings are connected to a vacuum pump (16) and the vacuum keeps the belt in intimate contact with the hot plate.The installation is particularly intended for use in assembling hybrid micro-circuits, whether using thin film technology or thick film technology.

Abstract: An apparatus is provided for heating a continuing series of articles, such as canned or bottled potable goods, to substantially room temperature in order to prevent condensation from forming on the containers. The apparatus comprises an elongated housing having an interior housing chamber and open on each longitudinal end. An endless conveyor transports the articles from one open end of the housing and to the other end of the housing along a substantially horizontal plane. An elongated trough is disposed under the conveyor and is partially filled with heating water so that the articles are partially submerged in the water as they are transported through the housing. A recirculation system is also provided for continuously reheating the heating water.

Abstract: In ovens which are divided by baffles to form zones, and through which conveyor belts pass, seals are positioned to prevent the flow of gases between zones. The seals are positioned between the baffle and the belt, and comprise a plurality of brushes extending from the baffle across the width of the belt and positioned so that at all times at least one of the brushes is in contact relationship with a non-foraminous portion of the belt.

Abstract: A baking method and a kiln to bake many tiles rapidly and continuously which comprises providing endless chains, set fire-proof L-shaped supporting parts that tiles are inserted into, which are provided with an inserting apparatus that puts tiles to be baked intermittently and nearly horizontally at the front end and a rotating loop belt, to receive baked tiles, covered by a wall for keeping them hot at the rear end, and, rotating said chains in and beside the kiln and passing tiles to be baked with holding them in a standing position through the kiln.
