Abstract: A filter element used for gas filtration, having a composite homogenous structure of inorganic fibers and reactant, the reactant reacting either physically or chemically with contaminants in waste gas passed there through in order to remove the contaminants and thereby enabling the filtered gas to be more safely released into the atmosphere.

Abstract: A heat activation method for activating a thermosensitive adhesive label having a support and a thermosensitive adhesive layer which is formed on the support and is not adhesive at room temperature, so as to make the thermosensitive adhesive layer adhesive with the application of heat thereto, includes the step of bringing the thermosensitive adhesive layer into contact with a surface portion of a heating medium, at least the surface portion of the heating medium being made of a silicone resin and having a peel strength of 2 g/mm or less with respect to the thermosensitive adhesive layer. There is also disclosed a heat-activating apparatus for heat-activating the above-mentioned thermosensitive adhesive label.

Abstract: A thermosensitive recording label including a substrate, a thermosensitive coloring layer formed on one side of the substrate, and a thermosensitive adhesive layer which is formed on the opposite side of the substrate and which includes a thermoplastic resin and a tack applying agent and which is usually non-adhesive and becomes adhesive when activated by heat, wherein the thermoplastic resin includes a natural rubber which is graft-copolymerized with a vinyl monomer.

Abstract: A thermosensitive recording adhesive label has a support, a thermosensitive coloring layer provided on one side of the support, and a thermosensitive adhesive layer which is formed on the other side of the support, opposite to the side of the thermosensitive coloring layer with respect to the support, and is adhesive above room temperature, with the thermosensitive coloring layer having a surface smoothness of 200 to 10,000 sec when measured by the method of Ohken-shiki prescribed in Japan Tappi No. 5, and the thermosensitive adhesive layer having a surface smoothness of 60 to 3,000 sec in terms of Bekk's smoothness.

Abstract: An apparatus for detecting internal pressure of a can has a reaction detector comprising two sets of fixed members and load cells arranged slightly narrower than the outside diameter of a can body and in a slightly different spaced apart from each other and a buckling detection sensor for detecting a displacement of the center of a cover. The reaction detector and the buckling detection sensor are mounted on a frame adjustable in position according to the kind of cans to be tested. The can is made to pass between two fixed members and load cells while being held by side retaining belts provided along the conveyor while being prevented from rotation. The same part of a can body is forced with different amounts of force and the reaction at that time is measured and converted into internal pressure of the can. The internal pressure of a can is thus measured accurately by this apparatus even if there are deviations in the roundness of the can body.

Abstract: An apparatus for flowing and filling liquified gases, which fuctions to flow and to fill liquified bases into cans from a liquified gas storage tank immediately before seaming of the cans. The apparatus includes a solenoid for attracting an upper portion of a needle of a flow valve formed from a needle valve to open and clode the valve. A pulse motor adjusts an opening-degree of the valve. A valve opening-degree detecting device detects the opening degree. A direction changing nozzle is formed with a nozzle opening obliquely descended in a direction of transporting a can, below the flow valve. A line speed and a balve open amount in a high speed region and a low speed region are respectively set to thereby obtain a line speed/valve opening-degree conversion table, on the basis of which an opening-degree of the valve can be controlled following the line speed.

Abstract: Apparatus for dropping and sealing liquefied inert gases into a can immediately before rolling of a canning can, and applying internal pressure to the can after sealed. Liquefied gases supplied from a liquefied gas main tank to a liquefied gas storage tank set in gas pressure lower than that of the main tank is controlled by a bucket or ball type float valve to maintain a constant liquid level at all times. A given amount of liquefied gases are dropped from a dropping nozzle into a can by means of a dropping valve actuated by a sensing signal of the can. Internal pressure of the storage tank is maintained constant by releasing vaporized gases within the tank through a regulating valve. This released gas shields the liquefied gases released and dropped towards the circumference of the dropping nozzle and the nozzle to prevent vaporization of the dropping gases and freezing of the nozzle. To prevent the nozzle from being frozen, it is preferred that a nozzle portion is made of a suitable synthetic resin.

Abstract: A method and apparatus for cutting and peeling the packaging material of an elongated package containing a product comprise gripping the packaging material of the package at the upper portion and all over the length thereof after said package is fed from a feeding section to a certain position in a cutting section, thrusting the cutting blades of a cutter member into the packaging material to cut a continuous cut line between the gripped upper side thereof and the product, forcedly peeling off the packaging material of the package fed to a certain position in a peeling section, discharging the exposed product into a delaying and storing section where the product is shifted stepwise and successively to be delayed and stored therein, and delivering the product to a discharging section where the product is received and discharged successively and intermittently.
