Title: Divided mirror for mirror reflex cameras, together with associated mechanism and swivelling prism plus mirror swivelling
Inventor: GEGGERLE SIGMUND DR
IPC: G03B19/12
Filed: 1987-12-31
Abstract: Divided, swivelling mirror for mirror reflex cameras, together with associated mechanism and swivelling prism. In order to permit a free lens design in which there is no longer a need, as there was before, to take account of the large mirror box, and thus no longer a need, as there was before, to accept a deterioration in the quality of the lenses in conjunction with an increase in volume and weight, the camera mirror is vertically divided and positioned more steeply by approx. 15 degrees, and the two halves are no longer folded upwards, but are swivelled to the left-hand and right-hand sides upon being triggered via an arrangement of rods and slides.

Title: Impeller of a centrifugal compressor
Inventor: VELIKANOV GENNADIJ FEDOROVIC
IPC: F04D29/30
Filed: 1988-01-18
Abstract: The impeller of a centrifugal compressor contains a bearing disc (1) and a cover disc (2), between the inner surfaces (1a) and (2a) of which working blades (3) are arranged. The leading edges (4) of the blades (3) are arranged on the leading side of the impeller in a plane which is perpendicular to the impeller axis (Z).

IPC: F23G5/20
Filed: 1988-11-23
Abstract: The invention relates to a process and a device for reducing the carbonmonoxide content in the waste gases of garbage-incineration installations.

Title: Treatment of Alzheimer's disease by chelating aluminium - using electron-rich oxine derivs., e.g. ester(s) or urethane(s) or 8-hydroxy-quinoline or -quinaldine
Inventor: LEHMANN HANS-DIETER DR
IPC: A61K31/47
Filed: 1989-09-28
Abstract: Reducing the toxicity of aluminium ions in humans comprises chelating them to form an electron-rich oxine structure. The uncomplexed precursor of the complex is broken down by oxidn., hydrolysis or a coupling reaction in the body, to form substances excreted by the kidney. The complexing agent is pref. an electron-donator-substituted quinoline or quinaldine oxidised at position 8, esp. the 8-hydroxy deriv. masked by an ester or urethane gp. The detoxifying process pref. uses citrate, cis aconitate and/or fluoride together with the complexing agent. USE/ADVANTAGE - Al(3+) ions are suspected of causing Alzheimer's disease, esp. where a deficiency of citrate ions exists. The complexes remove Al(3+) from the brain and bloodstream, and are readily eliminated by the kidneys. They have higher affinity for aluminium than citrate, and can therefore remove aluminium from citrate complexes.

Patent DE-4027908-A1 (DE)
Inventor: BERGER MICHAEL DR
IPC: F23G5/50
Filed: 1990-09-03
Abstract: The invention relates to a combustion method, for example for refuse incinerators, wherein fuel is burned with addition of combustion air which essentially consists of oxygen-enriched ambient air. It is proposed to feed combustion air having an oxygen content increased over that of ambient air only in those phases of the combustion process in which essentially the total quantity of oxygen is consumed down to a residual quantity which can be preset as desired. The combustion air of increased oxygen content is thus introduced under control in accordance with the actual requirements of the combustion process.
