Abstract: A cordless portable composite foam roller generates and applies heat and/or cold to muscles, and operates using an internal rechargeable power source combined with a flex-proof heating layer when in use. The cordless foam roller includes an elongated cylindrically-shaped body having a sandwich of heating layer(s) and textured exterior surface, and an inner cavity for hosting the rechargeable power source components.

Abstract: A portable heating device for heating plastic tubing or pipe has a straight, hollow heating tube with an inner diameter larger than an outer diameter of the plastic tubing or pipe to be heated therein. A hot air gun directs a flow of hot air into the heating tube. A heat adjustment mechanism holds the hot air gun at an adjustable distance from the plastic tubing so that the hot air flow at the input end is at an optimum temperature range for softening the plastic tubing. The device is inexpensive to manufacture and easy to assemble, and avoids the use of expensive mechanical components. An optional heat retaining tail piece equipped with a cooling fan may be used to transfer the hot air flow air quicker through the heating tube.

Abstract: A method for removing a twin-spool turbine including a front fan, a HP module with a HP rotor, and a LP turbine module, an intermediate casing including a support bearing for the HP rotor, the HP rotor being retained in the bearing by a link nut, the method including inserting a tool for unscrewing the link nut after having released access to the link nut, and preheating the link nut before starting the unscrewing tool.

Abstract: The continuous firing furnace includes: a single or a plurality of heating units (120), each of which includes a casing (120b) provided with a through-hole (120a) in a transport direction of a material to be heated, a heating section (160) that heats the material to be heated, and a movable section (150) that is provided at a lower portion of the casing and that supports and allows the casing to move in a horizontal direction, wherein through-holes are formed so as to be able to communicate with each other in the transport direction; a single or a plurality of cooling units (122) configured to cool the material to be heated, each of which includes a casing (122b) provided with a through-hole (122a) in the transport direction of the material to be heated, and a cooling section (170) that cools the material to be heated, wherein through-holes are formed so as to be able to communicate with the through-holes of the plurality of heating units; and a pressing section (124) configured to press the single or the plu

Abstract: A preheat burner assembly and method for preheating forming dies includes a frame, a burner manifold and a link assembly. The burner manifold as a plurality of burner orifices for preheating the forming dies. The burner manifold is connected to a fuel source. The link assembly mounts the burner manifold to the frame for movement between a stowed position and a deployed position. The burner is moved via the link assembly to a deployed position for preheating the forming dies. The forming dies are preheated. The burner manifold is subsequently moved via the link assembly from the deployed position to an upright stowed position.

Abstract: A carriage includes two or more beams each having a number of orifices for receiving a number of rods and for allowing the rods to be retained between the beams for supporting the objects to be heated by the kilns or furnaces. The beams each includes two end bulges each having a groove for receiving two ends of two bars, and for forming a stable supporting structure. The beams each includes a lower cavity and an upper projection for engaging with each other and for allowing the beams and the carriages to be superposed or piled with each other.

Abstract: Elliptically shaped reheater conduits extend downward into a portion of a flow path that extends through a lower chamber interior space of a kiln chamber. Each of the reheater conduits has opposite ends, defines a length that extends between the opposite ends and is perpendicular to the portion of the flow path that extends through the lower chamber interior space, defines a first cross-dimension that is perpendicular to the length and parallel to the portion of the flow path, and defines a second cross-dimension that is perpendicular to both the length and the portion of the flow path. The second cross-dimension is less than the first cross-dimension. Each of the reheater conduits defines outlets positioned along the length of the reheater conduit. Each reheater conduit defines a pair of vertices between which its second cross-dimension is defined, and the outlets are proximate the vertices.

Abstract: A semiconductor commutator which is constructed by joining a semiconductor region of the first conductivity type and a semiconductor region of the second conductivity type, wherein there is provided a grain boundary which is located near a junction surface of the semiconductor region of the first conductivity type and the semiconductor region of the second conductivity type so as not to cross said junction surface.

Abstract: A movable dryer for lumber products comprising a housing able to be displaced on rails secured to a slab and provided with a first roller bearing on the ground. A first motor is mounted on the housing and actuates a lifting jack which imparts a vertical movement to the housing. A second motor is mounted on the housing and actuates the first roller. A second roller assembly bears on the rails and is integral with the lifting jack. Provision is made for a fan for circulating the air through the housing and a heating device for supplying the required thermic operating gradient to the dryer. A control is provided for controlling the aforesaid dryer operations, thus enabling the dryer to be moved from a first resting location to a second one.

Abstract: This scrap metal preheat apparatus includes a conveyor made from deck plates which are of generally U-shape in vertical section, and an apertured or wire mesh metal support layer positioned on and conforming to the contour of the interior of the deck plate but spaced therefrom, which deck plate and support screen are of flattened U-shape in section, and supports for the deck plate, the apertured support layer being operatively secured to the supports and/or deck plate at the upper edge portions of the apertured support layer which overlap upper edges of the deck plate, and the apparatus includes support members for the support layer aiding in spacing it from the deck plate.

Abstract: A metal heating apparatus including a plurality of flattened U-shaped in section metal desk plates positioned in longitudinally overlapped relation to form a metal conveyor and an article receiving unit, a plurality of metal support plates or saddles below the deck plates and having complementary recessed upper surfaces contoured to receive and receiving the deck plates therein; bolt anchor means are positioned on the lower surfaces of the deck plates, and offset support means are secured to the saddle plates whereby bolt means can be attached to the support means and extend to and be secured to the bolt anchor means for anchoring the deck plates to the support means, but to permit some relative movement therebetween upon changes in heating and cooling conditions.
