Patent CH-655786-A5 (CH)
Title: Heat exchanger and use thereof
Inventor: CURTIUS FRIEDRICH
IPC: F28C3/18
Filed: 1981-07-03
Abstract: The heat exchanger is used for direct heat exchange between a steam flow and a colder flow of solid particles, and has a contact chamber (7) in which steam is condensed on the solid particles. A centrifuge device (8) having a centrifuge chamber (9) for the solid particles is provided in the heat exchanger, and condensate of the steam is immediately centrifuged from the solid particles again in this centrifuge chamber (9). In this way, the solid particles are heated by means of heat of condensation, but after leaving the heat exchanger are dry again and are not removed from the condensate. Such a heat exchanger can be used in a drying apparatus having a fluidised bed drier with a closed steam circuit, a proportion of the departing vapours being led into the heat exchanger in order to heat the flow of solid particles. <IMAGE>

Title: Resilient support for spherical gas or liq. storage vessel
Inventor: FEUERLEIN PETER DR ING
IPC: E02D27/38
Filed: 1976-04-21
Abstract: A spherical vessel for contg. gases or liquids is supported from beneath in the region of its vertical axis.  The support is provided by a layer of a material possessing elastomeric behaviour, firmly connected both to the underside of the vessel and to the upper side of the foundation.This layer is composed of separate support plates, covering the entire support area with the exception of narrow gaps between the plates; these gaps are filled with a sealing cpd.  The thicknedd of the support plates is pref. small by comparison with their area.  The plates may be perforated.  The support plates are of synthetic rubber based upon poly-2-chlorobutadiene.  The joints are filled with thioplast.The support provided to the lower dish of the vessel extends over almost the entire gross area, with the exception of the narrow gaps between the plates.  Effective support to the vessel is thus provided, whether it is full or empty.  The change in stress due to fluctuating load is thus considerably reduced.

Patent CH-559839-A5 (CH)
Title: Laminar lost formwork and reinforcing element - has rolled longitudinal stringers and intersecting cross bands from sheet strips
IPC: E04C5/06
Filed: 1972-08-18
Abstract: For use as lost formwork and reinforcement in concrete or mortar surfaces, and elsewhere, such laminar elements are normally made from punched-out sheet metal, or assembled from round iron bars and sheet strips. Intrinsic rigidity is here enhanced by producing both the rolled longitudinal shaped-sections and the alternately bent cross bands from strips of sheet metal. The bent cross bands and the longitudinal stringers may be interconnected by spot welding, or by detachable latching connection, and the longitudinal stringers may be laterally lattice-shaped. The cross bands may have holes through which concrete or mortar can trickle, to promote improved bonding.

Title: Automatic collecting device - for rusks at the oven outlet
IPC: A21C15/00
Filed: 1970-07-31
Granted: 1972-03-10
Abstract: Device is located at the end of a conveyor leaving the cooking oven. The rusks, arranged in longitudinal rows on the conveyor, arrive at the device which consists of a series of prismatic domes with vertical passageways between each dome to receive the rusks from the conveyor. It replaces the work of a number of persons who would otherwise be needed to remove the rusks from the rows by hand. The rusks are transferred by a blade to a box housing the prismatic domes where they tilt and fall into vertical passageways which have a width equal to the thickness of a rusk. On falling, each rusk meets a ball which causes it to tilt in its own plane so that it rests on the base of the passageway by its longeredge; the base of the passageway is formed by a conveyor which carries the rusks into corridors formed by flexible guides. The latter terminate in an outlet box; the rusks leave this in packets which are sent manually or automatically to a packaging machine.
