Title: Device for testing empty bottles
Inventor: YUGUCHI RENPEI
IPC: B08B9/46
Filed: 1988-10-08
Abstract: The device contains bottle-holding assemblies which, in each case, have a bottle fastening which is fastened on the upper end of a holding shaft and onto which the bottle is fitted, and a bottle-neck holder which is fastened on the lower end of a holding shaft and can engage in the bottle neck of a bottle.

Patent DE-3840696-A1 (DE)
Inventor: HENSELL BERND DIPL ING
IPC: B21B27/00
Filed: 1988-12-02

Title: Process and device for the cleaning and/or removal of layers of halohydrocarbon-containing residues on metallic surfaces by means of non-polluting treatment agents
Inventor: THEERKORN UWE DIPL ING
IPC: C23G5/00
Filed: 1988-12-22
Abstract: In the manufacture of metallic workpieces, a sealing protective layer for the surface is frequently required. However, before this protective layer is applied, cleaning or removal of layers of the surface is carried out. In this case, halogenated hydrocarbon-containing cleaning agents provide good service, but their value is reduced by the incompleteness of the cleaning and by the risk to the environment. The invention discloses a process and a device which detaches the halogenated hydrocarbon-containing cleaning agents in a fluidised bed (2) in a blasting gas atmosphere from the surfaces of the workpieces (1) and converts them into gaseous constituents. The outlet mixture at the exit of the fluidised bed (2) can then be separated by means of filters into non-polluting, pure and re-usable substances. Such a process with the associated device can be used from cleaning of a clip to removal of a layer from a car wheel rim, such that there is a wide field for the application. <IMAGE>

Title: Cleaning waste gas from wood drier by electro:filter - with cooled electrodes condensing water-vapour to form aerosol scouring film
Inventor: BOEHLER HARALD GEBHARD
IPC: B01D53/32
Filed: 1989-05-03
Abstract: Waste gases from wood-drying plant and contg. solid particles, tarry and resinous materials undergo preliminary spray washing before transfer to an electro-filter. Here the collector electrodes are cooled. Water vapour in the gases condenses on the cooled electrodes to form a descending liq. film carrying away both liq. and solid aerosol particles. The spray electrodes for the filter may also be cooled to form a similarly acting liq. film. Cooling is by electrically insulating liq., such as transformer oil. At least one of the two electrodes may be a tube of non-metallic corrosion-resistant material whose conductivity derives only from the condensate film, and cooled on to surface remote from the counter electrode. USE/ADVANTAGE - For drying veneers and other wood prods. Despite low power consumption, purificn. is effective in meeting legal demands, esp. on fine mist emission, with no problems for sticky materials.
