摘要:
A plate-type heat exchanger (1), comprising at least one stack plate pair (2) with in each case two stack plates (3, 4) aligned substantially parallel to one another such that between the in each case two stack plates (3, 4) there is enclosed a fluid-tight fluid duct (5) for conducting a fluid, in particular water, and comprising an inlet and outlet opening (6, 8) for the fluid, should be simple and cheap to produce and should be of compact design and should operate reliably. Said problem is solved according to the invention in that the heat exchanger (1) comprises at least one electrical resistance heating element (10), and the at least one electrical resistance heating element (10) is thermally connected to the stack plate (3, 4) and/or is mechanically connected indirectly or directly to the stack plate (3, 4), such that the fluid can be heated by means of the electrical resistance heating element (10).

An adhesive attachment assembly is provided for mounting an attachment member such as a threaded stud or the like onto a substrate, wherein the attachment assembly includes a heat source (18) for rapidly curing a selected adhesive bonding agent (16). The adhesive attachment assembly includes a first attachment component defining a base surface (24) for receiving the curable bonding agent thereon (16), and a second attachment component (28) adapted for temporary connection to the substrate. Upon pressed mounting of the first attachment component with bonding agent (16) thereon onto the substrate, the second attachment component (28) is movable into temporary engagement with the substrate, and a spring member reacts between the first and second (28) attachment components to apply a positive force urging the first attachment component toward the substrate for the duration of the bonding agent cure time.

摘要:
A heat distributing device (1) which includes a concentrated heat source (2, 2a) and a stack (3) of metal foils (4, 5) wherein the heat source is encapsulated between two of the layers of metal foil. The heat source can be a resistance heated wire which extends linearly and has a free end spaced inwardly from an end of the stack. The outer edge of the stack can be open (6) or sealed (7). The stack can include metal wool (8) and/or insulating material (9) between layers of the metal foil. The heat distributing device can be used to provide uniform heating across an outermost layer of the metal foil. For instance, the heat distributing device can be used to heat a side-view mirror (11) of an automobile.

摘要:
A floorcovering having a built-in heater which comprises a planar sandwich structure including an underlining layer of heat insulating material, at least one heating element provided on one surface of the underlining layer, an electric conductor provided on the one surface of the underlining layer so as to cover the heating element, a surfacing layer overlaying the conductor on one side of the heating element opposite to the underlining layer, and a lead wire for connecting the conductor to the ground.
摘要:
A diffusion pump includes a flat metal boiler plate (13) having an upper face (14) defining a floor for a pool of a vaporizable diffusion pump fluid or oil and a flat lower face (16) against which the metallic sheath (33) of a tubular electric heater (17) is pressed by a coextensive massive clamping plate (19). The heater (17) has a tendency to be overheated if only air is its thermal load. To prevent overheating of the heater (17) because of variations in the geometry of the heater sheath (33) which tend to cause air spaces between the sheath (33) and the face (16) of the boiler plate (13), a thin flexible metal crush plate (18) is disposed between the clamping plate (19) and the heater. The crash plate (18) has a plurality of spaced, raised dimples (37) adapted to contact many portions of the heater sheath (33) throughout the length of the sheath. As the clamping plate (19), the crush plate (18) and the heater (17) are urged toward the boiler plate (13) by nut and bolt assemblies (20, 21), the dimples (37) are deformed wherever they are in contact with the heater sheath. The deformed dimples (37) urge virtually the entire length of the sheath (33) into contact with the face (16) of the boiler plate and insure that pressure is applied to the heater sheath at the points of contact. Since there are many points of contact, the occurrence of local overheating, i.e., hot spots, is virtually eliminated.
