Title: Hot slat, esp. from waste incinerator, is cooled in trough - with water recycled back to trough after cooling and filtering
Inventor: HICK HELMUT
IPC: F23J1/00
Filed: 1978-03-18
Abstract: A method of continuously cooling hog slag from a combustion or firing plant, esp. a waste incinerator, consists of discharging the hot slag into a trough containing water, and maintaining the water level by make-up of cold water and removal of hot water. The hot water removed from the trough is cooled, mechanically purified and recycled back to the trough. During interruptions or faults which require the trough to be emptied of water, the extra quantity of water is stored within the recycling circuit plant. Pref. the hot water from the trough, passes to a slag bunker, then to a setting tank, to a pump chamber, and to a water collecting and mixing tank. Other process water may be introduced into the recycling circuit. By recycling the water, a minimum amount of discharge in to the public drainage system and thus a minimum amt. of pollution results.

Patent DE-2911981-A1 (DE)
Title: Gas pressure regulator for burner - has control element of offset spherical valve operated by gas pressure
Inventor: FEUCHT FRIEDRICH
IPC: G05D16/06
Filed: 1979-03-27
Abstract: Regulation problems at low valve openings are overcome by off-setting the pivots of a spherical valve, the position of which is controlled by the pressure of the gas entering the burner. A pre-set regulating spring, connected to a diaphragm which is operated by the falling gas pressure, opens the spherical valve via a bar. The pivot of this valve is offset relative to the axis of the opening through which gas enters, thus allowing some gas to enter the space behind the operating diaphragm via a channel, immediately the valve moves from the fully closed position. This results in greatly improved regulation at small valve openings.

Title: Viscosity determination on liquids - using calibrated capillary tube with mechanism to generate various rates of shear in the liquid
Inventor: SINN HARTMUT DIPL ING
IPC: G01N11/08
Filed: 1979-04-05
Abstract: Flow characteristics of liquids esp. biological liquids are measured by determining the pressure drop across a capillary tube section. A fixed volume of liq. is drawn through in a constant time and the pressure drop is accurately monitored. An auxiliary liquid can be used if necessary. The sample liq. is drawn through by a piston type pump through the test section to control its temp. under rest conditions. It is then pump. This is followed by a high shear action to determine the viscosity in the non-Newtonian region. For use on biological liquids esp. blood. Because the system is programmed, the measurement is easy and different liquids can be checked without problem.
