Title: Filter for aerating and venting aerosol-containing spaces
Inventor: BILLER GERD
IPC: B01D46/24
Filed: 1984-09-12
Granted: 1985-10-10
Abstract: A filter for aerating and venting aerosol-containing spaces is made up of at least two annular filter layers (3, 5) lying coaxially one within the other. Of these two filter layers, the first filter layer facing the aerosol space serves for separating out liquid particles from the aerosol flowing through the filter, whereas the second filter layer (5) facing the atmosphere serves for the separation of solids during aeration. To prevent exit to the atmosphere of liquid collected between the two filter layers, between both filter layers is mounted a perforated reinforcing wall (4), in which, however, the holes are absent at the axial ends up to a restricted height. As a result of the unperforated region of the reinforcing wall (4), the liquid collected in the intermediate space between the first filter layer (3) and the reinforcing wall (4) can only flow back into the aerosol space through the first filter layer. <IMAGE>

Title: Recovering masks after spraying car e.g. underseal(s) with plasticised PVC - by using hard PVC masks, removing them after the spraying, heating to drive off plasticiser and grinding down to granules for reuse
Inventor: HEILAND ROLF
IPC: B29B17/00
Filed: 1993-01-28
Granted: 1994-02-10
Abstract: Stable masks, for covering parts of car component, etc. which are coated with soft (plasticised) PVC i.e. to prevent those parts from being coated, are regenerated after use. In the process the masks are made of hard PVC and are removed when the components have been coated; the coating is then converted to hard PVC by driving off its plasticiser in a heat treatment; the masks obtained, which are now coated with hard PVC, are ground down to granules and these are fed to a conventional application. Pref. the underseal of cars is applied using hard PVC masks where required. The masks also become sprayed with the underseal, and are removed afterwards and collected, so leaving the bare areas concerned. The sprayed masks are e.g. passed through an oven so as to drive off the plasticiser from the coating but also the smaller quantity which was originally in the hard PVC masks. The accumulated hard PVC is fed to a disintegrator and ground down to granules. These are stored until required, when they are fed e.g.t o an extruder to produce e.g. drainpipes. The grinding process itself generates heat which aids the liberation of plasticiser. ADVANTAGE - The procedure recovers the masks after they have been coated with plasticised PVC.

Title: Working face air=conditioning method for underground mines
Inventor: HENTING HANS
IPC: E21F3/00
Filed: 1994-11-28
Granted: 1995-11-02
Abstract: The method involves the working face (1) being located between an air gallery (2) and a conveyor gallery (3). Air flows through the air gallery to the coal-face and leaves via the conveyor gallery. The water cooled air pre-cooler is located in the air gallery prior to the deep cooler (5) cooled with ice. In the air gallery the inflowing air is firstly fed through the pre-cooler and there cooled to the pre-cool temp.The pre-cooled air then arrives at the deep cooler where it is cooled to the end temp. of approximately 5 deg. C. This increases the air humidity to 100% as water condenses. The condensed water is disposed of by means of a water separator (6).
