Abstract: A method of producing a continuous fiber reinforced bent resin pipe, including winding a continuous reinforcing fiber on the outer surface of a tube-like flexible core mold while such core mold is straight in shape, the flexible core mold which is straight when unloaded being capable of keeping a cross section defined in radial direction when the core mold is bent. The core mold on which the continuous fiber has been wound is then bent and placed into a cavity defined by an outer mold formed of split molds each having an inner surface forming the predetermined outer configuration of a bent pipe. A liquefied synthetic resin is caused to be cured between the outer and the core molds to integrate both the fiber and resin. Thereafter the molded product is removed from the outer mold and the core mold is removed from the molded product.

Abstract: A process of packaging goods particularly foodstuffs in which the goods are placed in a first container for example a plastics bag or a tray having a deformable lid, sealing the container except for an aperture provided by an open valve.

Abstract: A pretreatment system for wheat to be floured comprises a plurality of friction type wheat polishing machines disposed in series relation to form a continuous wheat polishing process line. Each polishing machine includes a perforated tubular polishing member mounted on a frame and a frictionally polishing roll rotatably mounted on the frame. The polishing roll is disposed with the polishing member and cooperates therewith to define therebetween a polishing chamber. Upon the rotation of the polishing roll, it causes wheat grains supplied into the polishing chamber to be agitated and brought into frictional contact with each other to strip a pericarp from each wheat grain, to thereby polish the same. A moisture supplying device supplies moisture to the polishing chamber of at least one of the polishing machines, to add the moisture to the wheat grains flowing within the polishing chamber, to thereby increase a frictional contact force between the wheat grains.

Abstract: A method of detecting oil aerosol in an air flow. The contaminated air is passed between an electrode (11) and an electrically conductive catalyst (14), and an electrical discharge therebetween causes electrostatic precipitation of oil on to the catalyst. Air flow and discharge are stopped, and the catalyst is heated with the air substantially stagnant until the catalytic combustion temperature of the oil is reached. The heat generation due to such combustion is sensed and used to produce an output signal indicative of the quantity of deposited oil.
