IPC: B01J20/28
Filed: 1998-02-07
Abstract: The support grid comprises an expanded metal (2) with grid bridging sections (3) forming an angle with the grid plane.  Preferred Features: The structure is a multilayer (12-18) of expanded metal sheets in direct contact with each other. They are alternatively separated by spacers. The first layer in the airflow are electrically heated. Insulation intervenes between layers. Layers are connected in parallel or series arrangement. Layers in contact are adhered or soldered together. Layers, if appropriate with spacers, are tensioned together. Successive layers have differing grid bridging section orientation. They are preferably orientated by rotation through 90 deg  with respect to each other. The support structure is located in a plastic casing, preferably of high temperature-resistant plastic. Variations on the foregoing principles are also described. An absorbent coating on the grids is optimized for selective removal of various gases.  The first layer removes moisture and/or acid gases. A later layer removes hydrocarbons, especially from petrol.

Title: Nail file for finger nails
Inventor: SCHWARZ ADELBERT THEODOR
IPC: A45D29/04
Filed: 1998-02-11
Abstract: The nail file has a filing surface, consisting of a dry synthetic resin laminate film (e.g. melamine or phenol), which is applied to the file body under pressure and at temperature. At the same time, a special sieve-like filing surface structure is imprinted using a pressure sieve. Independent of direction of use, the sieve structure gives high abrasion combined with good smoothing. The file body consists of plywood, and after application of the resin coating, all layers are compressed, the structure is imprinted, and the final file shape is cut out, all in the same working process.

IPC: B01D7/02
Filed: 1998-03-12
Abstract: An assembly produces drinking water by extracting moisture from desert air with a relative humidity in the range of approximately 18 to 20 % using regenerative energy.

Title: Method for operating a drive piston in the drive cylinder of an injection system
Inventor: HAUSER DANIEL
IPC: B29C45/82
Filed: 1998-09-18
Abstract: A method is claimed for operating a drive piston (4) in a drive cylinder (5) of an injection system (1) of a moulding machine during an injection cycle, in which some fluid under pressure is delivered to the drive cylinder (5) in a predetermined phase of the injection cycle, on one side (12) of the drive piston (4), by a reduction piston (15) fitted to a part of the piston (16) of greater diameter to which is connected to a piston part (17) of lesser diameter. Essentially at the same time that this pressure is applied, a counter pressure acting in an opposite sense is equally delivered by a source of fluid under pressure (20) on the other side (9) of the drive piston (4). The pressure on this side is able to be modified and the drive piston (4) is thus pressed between the two forces acting in opposite senses.The device used to put this method into service is also claimed and incorporates a drive piston (4) in a drive cylinder (5) of the injection system (1) of a moulding machine. On one side (12) of the drive piston (4) the drive cylinder (5) is coupled to a reduction piston (15) fitted to a part of the piston (16) of greater diameter to that connected itself to a part of the piston (17) of lesser diameter. The other side (9) of the drive piston (4) and the drive cylinder (5) is coupled to a source of fluid under pressure (20) delivering a counter pressure in an opposite sense. This side (9) is associated with a device (7) for the adjustment of the pressure.
