Patent DE-3213597-A1 (DE)
Title: Exhaust gas purification system
Inventor: GRAMS HERBERT
IPC: F23J15/04
Filed: 1982-04-13
Abstract: The advantages achieved by the invention are, in particular, that a highly favourable and long-duration contact time of the exhaust gases with the scrubbing liquid is achieved by the oven channel scrubbing and mixing chamber scrubbing, by which means the scrubbing effect is optimised. Further advantages are that the circulation system for scrubbing liquid and also the heating system with exhaust air and fresh air have low capital costs and operating costs. However, it is essential that a large part of the gases, purified in the circulation system with scrubbing liquid, with added fresh air, is returned via a blower to the combustion oven. The advantage of this lies in the high preheating of the hot air (higher efficiency of the oven) and a very clean exhaust air, from which the majority of the impurities and also the sulphurous acid, sulphur dioxide etc., has been scrubbed out. When exhaust air is this clean, the dew point of sulphuric acid can be undershot, and in the extreme case the exhaust gases can leave the stack at room temperature without increasing environmental pollution.   <IMAGE>

Patent DE-3305945-A1 (DE)
Title: Loading platform for ramps
Inventor: ALTEN KURT
IPC: B65G69/28
Filed: 1983-02-21
Abstract: The invention is based on loading platforms for ramps which have a tilting platform plate which can be raised by a lifting cylinder and can descend automatically when the lifting cylinder is released. In order to be able to restore the platform into its rest position after operation thereof, the return pipe for the lifting cylinder is allocated a pressure switch which responds to a banking-up pressure occurring in the return pipe when the platform plate descends and controls the return of the platform plate into its rest position. Said pressure switch may be allocated a time switch which prevents the switch from becoming effective until after expiry of a certain time. Thereby errors as a result of the platform being straddled by heavy loads, which might also allow a banking-up pressure to occur, are eliminated.

Title: Filter spectacles
Inventor: GRIMM WOLFGANG DR RER NAT
IPC: G02B27/22
Filed: 1983-03-11
Abstract: Filter spectacles for viewing coloured images, in which a partial image in the form of a colour separation is offset in the horizontal direction with respect to the partial image containing all the other colours. Each eye of the viewer is assigned a filter. The spectral transmission curves of these filters form a region of minimum transmittance between the wavelength regions assigned to the partial images. The curves overlap in this transmittance region in such a way that the transparency there is 1-3%. The filter spectacles serve chiefly for viewing monoscopically taken television pictures in which the red record is offset in the line direction. The right eye of the viewer is assigned a red filter lens and the left eye a green filter lens, with the result that the viewer sees the television picture as three-dimensional.
