Abstract: The invention relates to a process for cleaning and decontaminating articles in a dry-cleaning machine with a filtered chlorofluorocarbon in a cleaning chamber. In order to simplify the cleaning and decontamination, the invention provides that, after introducing the articles into the treatment vessel of the dry-cleaning machine, an amount of water required for cleaning together with a cleaning intensifier sufficiently solubilising this amount of water in the solvent is added to the solvent bath, and after a certain period, the water content and dirt content in the bath is reduced or removed and that the bath is subsequently at least at intervals passed in a closed circulation through at least one microfine filter (Figure 2) via the piping system running from the treatment vessel. <IMAGE>
Patent DE-3710178-A1 (DE)
Inventor: GOEDECKE W D PROF DR ING
IPC: B30B15/16
Filed: 1987-04-01
Abstract: The control arrangement has a pneumatic-hydraulic power drive (14) with an actuating rod (17). The actuating rod (17) can be actuated pneumatically with small force over large distances by means of a working piston (40) and hydraulically with large force over small distances by means of a displacing piston (63). The displacing piston (63) can in turn be actuated pneumatically via a pressure intensifier (62/63). So that workpieces with freely programmable force/displacement profiles set in a controlled manner can be manipulated or machined, the actuating rod (17) is coupled to a displacement-measuring unit (20). The actuating pressure of the working piston (40) can be set independently of the actuating pressure of the displacing piston (63) as a function of an output signal of the displacement-measuring unit (20) (Fig. 2).

Title: Process and device for cutting ceramic material profiles
Inventor: PETAU ARNO DIPL ING
IPC: B26D5/30
Filed: 1987-04-21
Abstract: The aim of the invention is, with relatively low machine outlay and adequate cut quality, to prepare the profile sections such that they are grouped for automated removal. For this purpose, the profile section, cut to length by means of a cutting frame which is angularly adjustable as a function of the profile travel rate and the cut direction, is brought to a stop position, the latter being determined by a measurement sensor. When the further profile section, which has been cut to length in the interim, reaches this measurement sensor, the profile sections are conveyed jointly by one profile-section length. This process is repeated up to a predeterminable number of profile sections. Then the profile sections are jointly brought to a removal point, where a further measurement sensor triggers the automated removal. <IMAGE>

Title: Method for exactly adjusting bands (fringes, stripes) of an interference pattern parallel to an edge of a substrate
Inventor: HEISE GERHARD DIPL PHYS
IPC: G02B6/124
Filed: 1987-09-16
Abstract: For the lines or grooves (furrows) of an optical grating on a substrate (Sub) to run exactly parallel to a predetermined edge (Kt) of the substrate (Sub), the bands (Str) of the interference pattern (IM) used for generating the grating have to be adjusted so as to be exactly parallel to the edge (Kt). The novel method makes it possible for the bands (Str) to be adjusted in a very precise manner parallel to the edge (Kt). An optical deflection grating (BG) with grating lines (GL) which are resolvable at least with an optical microscope and lie exactly parallel to the predetermined edge (Kt) is generated on the substrate (Sub), which deflection grating (BG) is irradiated with an auxillary beam (HS) which lies in the plane (E1) or parallel to the plane (E1) of the two beams (S1, S2) generating the interference pattern (IM). The substrate (Sub) is adjusted such that the beams (gS, P) deflected by the deflection grating (BG) lie in the plane (E1) of the mutually interfering beams (S1, S2) or parallel thereto. Application to the assembly of integrated-optical Bragg reflectors on waveguides. <IMAGE>

Title: Method for eliminating hazardous exhalations in rooms
Inventor: HOELTER HEINZ DIPL ING
IPC: E04B1/72
Filed: 1987-10-17
Abstract: It is known that building materials are often used which, because of impregnation and similar treatment methods, exhale (emit) hazardous substances. In order to overcome this drawback it is proposed, according to the invention, that the construction surfaces themselves be provided with a chemisorbent layer which in turn is sealed off from the inside room by means of a visually attractive lining (covering layer). The chemisorbent layer can be equipped with vacuum drainage means. This advantageously takes the form of wallpaper (wall covering) which on its inside has an adhesive surface and behind which a chemisorbent layer is applied facing the wallpaper. The inner layer can take the form of a chemisorption filter compound.

Title: Method for ventilating a drying room
Inventor: HENNEL EWALD
IPC: F26B9/02
Filed: 1988-03-17
Abstract: A method for ventilating a drying room is specified, in the upper region of which articles to be dried are suspended and in the lower region of which people are located. Warmer air is blown into the upper region of the drying room than into the lower region and is also let out again. As a result, a boundary layer acting as a barrier forms between the two regions. The air from the upper region is thus unable to pass into the lower region of the drying room, with the result that the people located there are not exposed to any annoying smells.

Title: Mechanical, three-part car radio protection system for all makes of cars
IPC: B60R11/02
Filed: 1988-06-16
Abstract: To reduce theft of car radios it is necessary to present a system which, unlike conventional mechanical or electronic protection systems ensures that there is a stable "fixed connection" to the vehicle (splash wall). To achieve this it is necessary for the radio to be enclosed by a 'Part A' and then connected by 'Part B' to the splash wall and the associated 'Part C'. The connecting piece can, depending on the car producer, be adapted to the prevailing circumstances and therefore constitutes a variable connection, including a locking mechanism, between the car radio and the splash wall.

Title: Method for decreasing the concentration of vaporous condensable pollutants
Inventor: ERBEL HORST
IPC: B01D53/24
Filed: 1988-07-20
Abstract: In order to remove vaporous condensable pollutants, such as halogenated hydrocarbons, from air, it is known to cool the air to temperatures at which the pollutants freeze. Limits are set to this method, since at the lowest air temperature the air is saturated with the pollutant vapour. In order to decrease the pollutant concentration further, the air laden with pollutant is fed to a gas centrifuge (5) which divides it into a high-pollutant and a low-pollutant fraction. The high-pollutant fraction is cooled to condense out the pollutant and is returned again to the gas centrifuge (5) together with the low-pollutant fraction. The method is particularly suitable in degreasing units operating with chlorinated hydrocarbons. <IMAGE>
