Abstract: A piping jacket for insulating a piping element to prevent heat transfer and to protect the piping element from moisture and other elements. The piping jacket has a first edge portion with a curved edge and a second edge portion with a plurality of projections that interfere with the curved edge to secure the piping jacket around a piping element when the piping jacket is in a closed position. The piping jacket can have two or more rows of projections along the second edge portion to accommodate piping elements having different outer diameters. The piping jacket can also be formed by two separate body sections positioned around a piping element and pressed together so that projections along a first edge portion and a second edge portion of the inner body section interfere with the curved edges of a first edge portion and a second edge portion of the outer body section.

Abstract: A tool holder for a tool drive with an outer and an inner concentric drive shaft. A first adapter is detachably held by a conventional clamping system in a receptacle of the outside drive shaft. A second adapter is concentrically mounted in the first tool receptacle of the first adapter so as to rotate with respect to the first adapter. The second adapter has a tool receptacle which can be inclined by a pivoting element. Thus, a tool can be eccentrically inserted and concentrically driven. This makes possible certain machining modes, for example the machining of a hollow shaft, since inner threads can now be turned rather than cut.

Abstract: A natural draft combustion system having a housing enclosing at least a portion of a material heating container and at least one combustion space in heat exchange relation with the material heating container and extending from a heat inlet side of the housing to a heat outlet side of the housing. A downward angled burner having a burner outlet in fluid communication with a heat inlet to the at least one combustion space is disposed on the heat inlet side. A natural draft combustion products exhaust conduit in fluid communication with the at least one combustion space is disposed proximate the heat outlet of the housing. As a result, a flame produced by the burner is introduced into the combustion space with a downward velocity component, which, in turn, results in improved efficiency over comparable conventional systems.

Abstract: A fluid transfer apparatus utilizing a slanted cain disk to oscillate and rotate a set of pistons arranged in a circle. Channels associated with the pistons and piston housing effect the transfer of fluid from a first location to a second location, as well as the pressurization or depressurization of the fluid, during movement of the pistons. The apparatus can be used as a high-pressure fluid pump, a fluid-powered motor, a fluid distribution valve, or another fluid transfer device.

Abstract: An absorption heat pump achieves improved efficiency by lowering the low cycle temperature of the circulation fluid. This is accomplished by adding a crystallization-inhibiting compound to the circulation fluid which substantially depresses the temperature at which the absorbent salt in the fluid begins to crystallize.

Abstract: An apparatus and method for increasing the heating efficiency of a nonwoven web using heated air are provided. A flow modifier including a turbulence inducing bar arrangement is positioned between the heated air supply and the nonwoven web. The flow modifier increases the turbulence of the heated air before it contacts the nonwoven web, resulting in more thorough penetration of the web by the air, and better convective heat transfer between the heated air and the nonwoven web.

Abstract: A remotely controllable gaseous fuel burner having a burner body with a fuel inlet, a fuel outlet, and a constricted throat region immediately upstream of the fuel outlet. A concentrically disposed and longitudinally movable fuel conduit is disposed within the burner body forming an annular region between the burner body and the fuel conduit. The fuel conduit having a conduit fuel outlet forms a conduit fuel inlet in a wall of the fuel conduit. The outer surface of the conduit fuel outlet immediately upstream of the conduit fuel outlet is tapered and has an outside diameter larger than the inside diameter of the constricted throat.

Abstract: An absorber and evaporator combination for use with an absorption heat pump (including chillers and air conditioners) as well as with other apparatus in which a vapor is absorbed by a liquid absorbent or a liquid or gas is cooled by evaporative cooling is disclosed. The absorber and evaporator are designed as vertical plates that can receive films of either absorbent (on the absorber) or refrigerant (on the evaporator) flowing down them. A liquid refrigerant is distributed across the top edge of each vertical surface of the evaporator. Likewise, for the absorber, a liquid absorbent is distributed across the top edge of each vertical surface. The distributors for the refrigerant and the absorbent are constructed and arranged so that they distribute their respective liquids without creating droplets. In one embodiment, two vertical evaporator surfaces and two vertical absorber surfaces are assembled into one absorber/evaporator panel.

Abstract: A switching cabinet having a rack with an upper and lower frame and vertical and horizontal struts which are disposed horizontally. The upper and lower frame have corner cavities, to which vertical frame profiles can be connected. The vertical frame profiles have profiled segments which are turned towards an inside of the rack. Access to the inside of the rack is improved when the vertical frame profiles may be mounted or dismounted afterwards which can be done with few components and involves little effort during mounting by including vertical profiles on at least one side of the rack, whose ends and profiled segments can be inserted into the corner cavity from the outer side of the rack, and by placing and fixing the profiled segments onto the connector of a corner cavity.

Abstract: An arrowhead having at least one blade, preferably between two to six blades, which are interchangeably mounted in a pivotal or a fixed position with respect to a blade carrying body. A pin is used to retain a corresponding blade in a pivotal or a fixed position with respect to a blade carrying body. When the blade is pivotally mounted a bias force of a retaining member is preferably selected so that each blade remains in a normally closed position during flight or during handling of the arrowhead, but yet responsively and quickly moves to a fully open position upon impact or when a sufficient opening force is applied to the blade. A blunt leading surface of the pivotal blade in its normally closed position presents a convex curve to the target surface thereby insuring good transfer of opening force to the blade when striking the target.

Abstract: A switch cabinet having a rack with vertical frame pieces, wherein the vertical frame pieces are coupled to a lower unit or to an upper unit. Electronic components can be assembled by connecting two adjacent vertical frame pieces to a separate assembly unit with connecting elements and by fixing the components to be assembled.

Abstract: This invention relates to a package of a plurality of containers unitized with a flexible carrier. The carrier is constructed from a plastic planar sheet having a plurality of container receiving openings arranged in longitudinal rows and transverse ranks.

Abstract: An adapter with an adapter housing, which can be fixed in place on the bus bars of a bus bar system and which receives terminal contacts, which can be connected in an electrically conducting manner with the bus bars. An equipment holder for fastening electrical installation equipment can be connected in various positions with the adapter housing. The equipment holder has holding elements and the adapter housing has receiving elements for the holding elements of the equipment holder. Continuous adjustability between the equipment holder and the adapter housing is achieved because the holding elements of the equipment holder are designed as support strips, which can be inserted into receiving elements of the adapter housing which are embodied as receiving grooves, or as edge strips, and which are continuously displaceable along and fixable within the receiving elements.

Abstract: A die system for the extrusion of polymer permits external cleaning and maintenance without shutting down the operation. Removable die inserts are located on one or both sides of the die opening section through which polymer is extruded. The inserts are spaced from the die opening section, by a very small distance, so as to avoid interfering with the opening section. When molten polymer accumulates and burns in areas surrounding the die opening section, the inserts can be removed and replaced without interrupting the extrusion of polymer.

Abstract: A switching cabinet with a rack having a base made of length and depth struts with connected vertical frame pieces. The vertical frame pieces are inserted into a cavity formed by the ends of the length and depth struts and are welded with the base to form a corner connector. It is possible to create a switching cabinet with a simple corner connector mounted on the rack. It is also possible to achieve precise alignment of the vertical frame pieces by providing them with centering pieces which are aligned with stops of the length and depth struts.
