Abstract: There is disclosed an arrangement for mounting a heating coil relative to a supporting wall of a clothes dryer heater housing. An insulator has a main body portion adapted to secure the heating coil relative thereto and a base portion adapted to be seated in fixed relation to the supporting wall. The base portion has first and second flanges which curve downwardly and outwardly from the insulator. The support wall has two raised tab members which are adapted to define between these tab members and the supporting wall a recessed channel for receiving the first flange of the insulator. The supporting wall further has two spaced apart guide members for engagement with opposite sides of the second flange of the base member to prevent relative lateral movement of the insulator. The supporting wall has a pivotably movable locking flange which is pivotable about a crease located between the two guide members. The locking flange has a hook adapted to move into engagement with the second flange of the insulator to prevent the insulator from being pulled away from the supporting wall surface.

Abstract: An acid corrosion inhibitor composition is provided for petroleum wells and water wells subjected to stimulation with acid solutions. The inhibitor combines cinnamaldehyde and preferably an organo-sulfur compound. The inhibitor provides a reduced rate of corrosion and fewer instances of pitting than inhibitors which include cinnamaldehyde alone.

Abstract: A firestop coupling assembly (10 or 210) for allowing the passage of utility members (50 or 52) through a penetration in a partition (54 or 56) while preventing the transmission of fire and smoke through the penetration. The coupling assembly includes an outer sleeve (12 or 212) and an inner conduit (16 or 216). The outer sleeve has a concentric indention (12D or 212D) around its inner surface within which is mounted an intumescent material (20 or 220). In one (1) embodiment, the inner conduit is mounted in the open top end of the outer sleeve so that the second end (16B or 216B) of the inner conduit is adjacent the intumescent material. In another embodiment, the inner conduit is adjustable along the length of the outer sleeve. A plug (22 or 222) can be provided in at least one end of the inner conduit allowing passage of at least one (1) utility member through the assembly. In another embodiment, the inner diameter of the inner conduit is only slightly greater than the outer diameter of the utility member so that the utility member can be solvent welded to the inner surface of the inner conduit. When the coupling assembly is exposed to heat, the intumescent wrap expands into the inner passageway of the outer sleeve and prevents the transmission of smoke end fire through the coupling assembly.

Abstract: A freshness-retaining agent for an agricultural or horticultural product comprises an organic acid and a hydrgencarbonate. The organic acid may preferably be an organic acid which in the presence of water given off from the agricultural or horticultural product, reacts with the hydrogencarbonate such that carbon dioxide gas is gradually generated, for example, cinnamic acid, benzoic acid or citric acid or a derivative thereof. The hydrgencarbonate may preferably be sodium hydrogencarbonate. The freshness of the agricultural or horticultural product can be retained by causing the freshness-retaining agent to exist in the same atmosphere as the agricultural or horticultural product such that the freshness-retaining agent is allowed to gradually generate carbon dioxide gas in the presence of water given off from the agricultural or horticultural product.
