Patent DE-2362885-A1 (DE)
Title: Radiator block for engines - having pressed sheet metal heat transfer surfaces with staggered crimp for greater rigidity
Inventor: MOSOCHIN NIKOLAJ GAWRILOWITSCH
IPC: F28D1/053
Filed: 1973-12-18
Abstract: Radiator block for i.c. engines consists of two water feed headers with tubes running between them. In between the rows of tubes crimped plates are inserted to provide flow channels for the cooling air with extended heat transfer surfaces. The channels have direction changes at regular intervals causing each section to be offset from the previous one. Each plate has a series of such channels running parallel to each other. They are arranged symmetrically around a central axis of the plate. The plates are formed from an aluminium alloy. Sheets made in this construction have a greater intrinsic stability than a simple straight crimp. This means that a much thinner gauge sheet can be used to give effective contact of the tubes. Cheaper material such as aluminium can be used without the need for resorting to copper, brass and using lead/zinc solder. Maximum heat transfer is achieved for minimum weight. Plates can be placed back to back between tubes or a single plate can be used.

Title: Sludge density measuring device - having electrical analog output, using ultra-sonic input
Inventor: FRAHM JUERGEN
IPC: G01N29/032
Filed: 1974-11-26
Abstract: In a process for measurement of sludge density (solids concn.) by damping effect on ultrasonic waves employing piezo-ceramic converters in a water-tight immersed probe, a low-drift measurement analogous to damping measurement value is achieved by energising the converter with individual electrical impulses, each of which produces a single pattern of mechanical oscillations whose ultrasonic intensity is substantially dependent on the mechanical properties of the converter and its h older. The impulse-sequence frequency is selected at a sufficiently low value to ensure resonance of the converter and to ensure that the rest-properties of the converter can be reset before the next impulse is introduced. Used for measuring sludge density in pipeline flow or finding the level of sepd. solids in sludge thickness. A stable, reproducible analog output is obtd. together with simultaneous indication of mean solids concn. using only one probe.

Title: Diesel engine cylinder head - for easy reconditioning has brazed chrome alloy combustion face and cast steel flange
Inventor: JONES JUN ROBERT HOWARD
IPC: F02B1/04
Filed: 1975-02-19
Abstract: Cylinder head of a large Diesel engine (for locomotives) is a cylindrical body which represents by the face at one end a combustion surface and is sub-divided by ribs close to this surface into cooling channels. Axial bores provide access for valves and injectors. The face at the combustion side carries a brazed insert made of an iron-chrome alloy with the same expansion coefficient as the body. Service life of an iron-chrome insert is several times longer than that of a cast iron cylinder head. The absence of oxidation scale permits a better contact and heat transmission from metal to coolant. The main body (35) of the cylinder head is joined by brazing to the flange (16) and can be fixed together with it to the cylinder liner (shown dotted) by bolts through the bores (15). A recess (34) at the bottom receives an insert (36) made of an iron-chrome alloy which is also brazed to it. A spigot (14) ensures a good seal against the liner.
