Abstract: A heat exchanger has a plurality of like plates each in turn provided with a base portion substantially on and defining a base plane and having a pair of generally parallel opposite outer edges, and respective lips bent upward from the outer edges and forming and lying on an attachment plane substantially parallel to the base plane. Adhesive bonds or welds secure the plates together in a stack to form generally perpendicular flow passages parallel to the plane. The lips of each plate extend generally perpendicular to the lips of the adjacent plate and the plates are secured together with the connection plane of each plate lying on the base plane of an adjacent plate. Each plate is formed between the respective opposite edges with a plurality of integral bumps projecting from the respective base plane toward the respective connection plane. These bumps each have an apex lying on the respective connection plane.

Abstract: The invention relates to an apparatus for making up feed water for a power station having a steam circuit with a steam turbine /3/ and a feed water circuit with a turbine condenser /5/. The apparatus comprises aregulated multi-stage adiabatic evaporator/5/ produces distillate from raw water for making up the feed water. The heating inlet /8/ of the evaporator /15/ is connected to the stream circuit through an ejector /14/. The distillate outlet /36/ of the evaporator /15/ providing distillated water, is connected to the feed water circuit at the turbine condenser /5/ or after it through water delivering means /19, 20/.

Abstract: Convector with finned tubes [1, 2, 3, 4] for conducting a first heating medium and an upright channel [42] for a second medium around at least one of the finned tubes [1]. A lower finned tube [1], a side finned tube [2] and an upper finned tube [3] are rigidly connected in series for the first medium so that they constitute a self-supporting structure. The side finned tube [2] constitutes a first side bording element for the upright channel [42], the second side bording element is either a further side finned tube [4] rigidly connected in parallel or a stiffening side plate [60].

Abstract: A power assisted steering gear having a movement transmitting drive member connected to and rotatable with the steering unit, one portion of which that determines the axis of rotation is formed by the connection between the steering nut and drive member. Another portion is formed by a ball pivot fitting into the nest of a double acting piston and a further ball pivot fitting into the nest of an axial slide valve of the piston which is set outside the axis of rotation.

Abstract: The invention is, on the one hand, a heat exchanger comprising at least one tube (1) and at least one ribbing made of a heat conducting material folded to a concertina-like shape, where the ribbing has ribs (2), each of them being substantially perpendicular to the axis (10) of the tube (1) and comprising wings (4A, 4B) and a rib base (3) between them, and where the ribs (2) are attached to the tube (1) at their rib base (3). At least one of said wings (4A, 4B) of each ribs (2) comprises patterns interrupting the continuity of the wing material, and/or bent surfaces making an acute angle (.alpha.) to a plane perpendicular to the axis (10) of the tube (1). The patterns may be cutouts (7A, 7B), holes (8), outpressed parts (9) or embossings (17A, 17B).

Abstract: Apparatus for carrying out thermodynamic processes in which a work medium undergoes mutually opposite phase transitions. The apparatus comprises casings consisting of confining plates and spacers therebetween, the casings being arranged in stacked relationship. Each casing encloses a plurality of phase transition compartments in superposed relationship. There are orifices in the confining plates through which pairs of phase transition compartments open directly into one another so as to form a number of work chambers. These are also passages delimited by the spacers in the casings for connecting the work chambers in series and passages delimited by the spacers in the casings for introducing and drawing work medium into and from the phase transition compartments. Finally, there are passages delimited by the spacers in the casings for supplying and abducting heat to and from the work medium.

Abstract: The invention is, on the one hand, a method for drying products, especially corn or articles, in the course of which the products to be dried are traversed by a drying gas, the moisture content of the drying gas is diminished by contacting it with a desiccant liquid, and the desiccant liquid is at least partly regenerated after the contact. According to the invention, the drying gas stream flows through at least two layers of products to be dried successively, and before or after flowing through each layer of products it is brought into contact with the desiccant liquid.

Abstract: A method of and apparatus for drying products with a gas stream passing the product to extract moisture therefrom and a contacting device producing at least one desiccant liquid layer in the vicinity of the product to be dried, which liquid layer removes moisture from the gas. The gas stream is bubbled through a substantially horizontal liquid layer or can pass between liquid film conducting elements. The desiccant liquid is continuously regenerated. By means of several partial gas streams and a contacting device having more separated liquid film modules, a counter-current type of drying is possible. The product to be dried can be heated to a predetermined temperature by the desiccant liquid through the drying gas stream.

Abstract: Hydraulic servo steering gear having a cylindrical, double-acting working piston connected to a steering shaft by a rack-and-sector gear connection, especially for motor vehicles comprises a piston-and-sleeve type control mechanism arranged in the working piston. The cylindrical outer surface of the sleeve of the control mechanism is fitted loosely, with a radial gap, in the seat formed therefor in the double-acting working piston. The control sleeve is secured against axial and angular displacement.

Abstract: The invention concerns hydraulic control valves suitable for e.g. motor vehicle steering gear. A variety of control port configurations are formed between cooperating ribs and bores on the control piston -- which may be rotary or axially displaceable -- and on the control sleeve. In each case the resulting control ports are defined by circular arcs having a common chord arranged at right angles to the direction of the control displacement for example at right angles to the direction of the control displacement for example at right angles to the direction of rotation of a steering spindle.

Abstract: An apparatus for use in transferring heat and mass, having a receptacle for a liquid with a pile lock and a liquid distributor surface onto which the pile lock supplies a film of the liquid. The distributor surface faces downwards and liquid withdrawing means act to withdraw the film of liquid from the surface and carry it to an outlet means. The heat and mass transfer takes place on the liquid withdrawing means.
