Patent DE-4215997-A1 (DE)
Inventor: LAUTENSCHLAGER GERT DR
IPC: F23G5/50
Filed: 1992-05-13
Abstract: Whereas in the state of the art a constant combustion power was sought in waste incineration plants, so that different amounts of waste were supplied to the incineration grate depending on the calorific value, it could be ascertained the legal requirements concerning the degree of combustion could be better complied with by maintaining on the grate a layer of materials to be burned having a uniform thickness. Grate loading and transport speed of the material to be burned, generated by movable grate bars, are thus regulated depending on the amount of waste on the grate or its zones. The hydraulic pressure of the grate drive is used for measurement and regulation.

Title: Compressor discharge flap valve - has inclined stop which changes angle in region of valve flap attachment for progressive action
Inventor: KAWAI KATSUNORI
IPC: F04B39/10
Filed: 1992-08-11
Abstract: The aperture (18) in a valve plate (4,5) is opened and shut by a flap valve (20) with a disc-shaped head section (20a) continuing into a neck section (20b). A holding member (21) mounted to the valve plate (4,5) has an inclined surface (21a) which determines how far the flap valve (20) opens. The angle of the inclined surface (21a) changes in the area contacted by the head section (20a) of the valve (20) when the aperture (18) is fully open. USE/ADVANTAGE - Curved geometry of valve stop prevents the valve flap from sticking to the stop, thus avoiding reduced volumetric efficiency caused by delayed return.

IPC: G01N27/447
Filed: 1993-06-15
Abstract: An assembly washes a sample depositor which is used to place a serum sample in an electrophoresis sample (serum) holder by means of electrophoresis. The novelty is that the assembly incorporates: a vessel (11) to hold a buffer soln.; a transporting medium (21) to hold one or more sample depositors (25), such that one end of the serum holder is brought in contact with a buffer soln.
