A process for manufacturing expanded polystyrene panels includes the following stages: (a) Preparation of pre-expanded panels of polystyrene by extrusion and simultaneous injection of propellent agent into an extruder fitted with an extrusion die of suitable type and in particular fitted with means allowing for good mixing of the molten polymer with the propellent agent and means allowing for unif...

Weld seams of parisons formed in an inert atmosphere during extrusion followed by blow molding with a blowing gas containing an oxidizing agent are extremely strong when compared with conventional seams formed in the presence of air. By sealing in an inert atmosphere and subsequently blowing the parison with a mixture of nitrogen and fluorine, a container is produced having both high weld seam str...

PURPOSE:To detect the excitation of resonance and the detection of two nuclides independently by arranging two coils on a cylindrical surface parallel with the axis of a sample tube diagonally while crossing each other at the right angle while a third coil is arranged on the axis intersecting said two coils at the right angle. CONSTITUTION:A first detection coil is arranged on the outer surface of...

PURPOSE:To obtain surely a device for combining strings which uses a plastic combining member with strong adhesive connection by following method in which the combining parts of strings are kept at the predetermined position on the tops of protrusions in the forming space for a combining member in the internal cavity of metal dies, and at this condition injection molding is carried out. CONSTITUTI...

PURPOSE:To make an exhaust gas purifier compact by constituting the valves which control the secondary air by means of the suction pipe negative pressure and car speed in an integral structure. CONSTITUTION:When an engine is decelerated, a throttle valve Vth is closed and due to the large suction pipe negative pressure a high negative pressure is applied to the chamber b of a diaphragm 46 through ...

PURPOSE:To prevent the ternary catalyst from being burnt by cutting the supply of the secondary air during the deceleration and acceleration of an engine and a high load operation. CONSTITUTION:Two diaphragms are provided on a control valve V, and the negative pressure downstream a throttle valve Vth is applied to one diaphragm 46, and the atmospheric pressure or said negative pressure is applied ...

PURPOSE:To make an exhaust gas purifier compact by reducing the pipe lines of valves which cut the secondary air of an exhaust system during the deceleration and acceleration of an engine and a high speed operation. CONSTITUTION:Two valves 38, 39 driven by two diaphragms 46, 53 are integrated into a valve body V, to which a solenoid transfer valve 57 is fitted to form a unit. When an engine is dec...

PURPOSE:To fit the catalyst with no damage by compressing a flat plate-shaped shell to a monolith catalyst periphery by use of a predetermined shape mold. CONSTITUTION:A wire net cushion material 3 is wound around a monolith catalyst 1', and they are placed between mold frames 6, 6' with predetermined curves 6a, 6a'. An outer shell with an overlapping bent section 2a formed at one end of a flat pl...

PURPOSE:To obtain a secure seal with less number of parts used by forming a V-shaped recess at a joint between an exhaust manifold and a catalyst container and by providing a V-shaped seal there so as to contact under pressure with the catalyst. CONSTITUTION:When a ''Monolith '' catalyst 1 is to be installed below an exhaust manifold 11, the flange of the exhaust manifold 11 and that of a catalyst...

A filter for intravenous liquid administration is provided having a filter housing; a filter chamber in the housing; an inlet member and an outlet member in the housing in fluid flow communication with the filter chamber; a filter in the filter chamber disposed across the line of fluid flow through the chamber from the inlet member to the outlet member so that all through flow must pass through th...

PURPOSE:To achieve the bottom-adhesion of a tubular vessel having high adhesion-strength without scattering the powder and particles of synthetic resin by applying ultrasonic vibration to the flat bottom of said vessel made of synthetic resin with a mouth part retained downward, in the direction crossing the bottom obliquely. CONSTITUTION:A piston rod 13 and a press-plate 14 are pulled back by t...
