Abstract: A design of finned units, intended for example for thermal regenerators, heat exchangers or burners for liquid fuel. The finned units are manufactured by simultaneous spiral winding of a strip forming fins and a spacer element forming a distance between the fins. The spacer elements are wholly or partially removed when fixing elements have been introduced in a number of holes distributed about the circumference. The cross-sectional area of each fixing element is equal to or smaller than the cross-sectional area of the corresponding holes in the fins. As a consequence thereof each fixing element prevents movement of the fins exclusively in a plane perpendicular to said fixing element.

Abstract: A cover assembly is used for retaining members such as the heat exchanger elements of a heat exchanger in clamping engagement with a diaphragm which is interposed therebetween. The cover assembly has an inner plate and an outer plate which form a chamber within which a fluid medium is contained. The fluid is pressurized to provide force distributed uniformly over the surface of the inner plate, thereby enabling this plate to resist forces which would otherwise tend to cause it to buckle, and assuring clamping pressure to clamp the members together over their entire contact area to enable good thermal transfer therebetween.

Abstract: As a permanently implantable fixture means for prosthesis and the like in a human body, especially for implanting a dental prosthetic structure, a means composed by at least two parts has been proposed for attaching the prosthetic structure to bone tissue. A first part of the attachment unit is intended to be applied in such a way in the bone tissue that it will remain embedded in said tissue during all of the time required for healing the damage which occurs when the first part is attached to the bone and while the bone tissue grows into the attachment, and a second part of the attachment unit, serving as mounting unit for the prosthetic structure and so shaped that it may be attached to the first part of the attachment unit and pass through such weak tissue covering the bone tissue. The mounting unit is intended to combine the attachment unit inserted into the bone tissue with a prosthetic structure located outside of the weak tissue. Such permanently implantable attachment means have been used for permanently attaching dental prosthetic structure to the jawbone in human bodies. The jawbones rather often have a narrow crosssection, and the longitudinal direction of the cross-section may be diverge sharply at different parts of the same jaw and/or the same jawbone but especially between the upper jaw and the lower jaw. This, among other reasons, results in so-called over-bite or under-bite, respectively. As the attachment units must, for technical reasons, be well centered in the jawbone, the longitudinal directions of the attachment units will not always be in alignment mutually in the same jaw, nor between the upper jaw and the lower jaw. This is a serious disadvantage, because the longitudinal direction of the teeth in the prosthetic structure should be in alignment with the longitudinal direction of the attachment unit. A compromise between these demands either a weak or completely unsatisfactory attachment in the jawbone or non-aligned prosthetic structure. Therefore, there is a need for an attachment means of the kind indicated above, in which the said first part attached to the jawbone may form an angle with the said second part to which the prosthetic structure is attached.
