Granted: 2010-05-25
Abstract: An injection needle particularly intended for transferring a representative fluid sample into a sample bottle (1) which is closed by a membrane (2) made from a rubber elastic material. The needle comprises a tubular inner wall (6) having a needle point (8), and a tubular outer wall (10) concentrically surrounding and radially spaced from the inner wall (6) at least along a portion thereof distant from the needle point (8) and, at its end facing the needle point, having a conically tapering portion (12) sealingly engaging the inner wall (6). The outer wall (10) is provided with at least two apertures (14, 16) spaced longitudinally of the needle. When using the injection needle for the above purpose, fluid is injected into the sample bottle (1) from a fluid source of interest, by inserting the injection needle into the sample bottle through the membrane to a level at which the penetrated portion of the membrane (2) sealingly engages the outer wall (10) of the needle between the spaced apertures (14, 16) in the outer wall, such that initially some of the fluid that is injected into the bottle is allowed to flow into the annulus between the inner and outer walls of the needle (4), through the aperture (14) of the outer wall at the inside of the membrane, and hence out through the aperture (16) of the outer wall at the outside of the membrane.

Title: Method and device for producing an insulating glass pane
Inventor: LISEC PETER
IPC: E06B3/663
Filed: 2005-06-13
Granted: 2009-09-15
Abstract: The invention relates to a method for producing an insulating glass pane while using an elastoplastic strip as a spacer, during which the strip is drawn from a supply reel and, with one of its lateral faces, is pressed onto the first glass pane while forming a spacer that encircles near the edge, and afterwards the second glass pane is placed upon and pressed. The inventive method prevents the strip pressed onto the first pane from shifting before and, in particular, when the second glass pane is pressed on. To this end, an elastoplastic strip is used that has stepped lateral faces of which the upper strip-shaped partial surfaces are coated with a highly adhesive, film-like glue, and the slightly lower strip-like partial surfaces are coated with another glue that is water-vapor diffusion-tight, particularly a butyl glue, before the strip is pressed onto the first glass pane. The upper partial surfaces of the lateral face of the strip are preferably already coated with the highly adhesive, film-like glue during the production of the strip and are covered by protective films until the strip is used. The protective films are removed immediately before the water-vapor diffusion-tight glue is applied to the lower partial surfaces.

Abstract: The invention relates to a method of synthesizing a mono audio signal based on an available encoded multichannel audio signal. The encoded multichannel audio signal is assumed to comprise at least for a part of an audio frequency band separate parameter values for each channel of the multichannel audio signal. In order to reduce the processing load in synthesizing the mono audio signal, it is proposed that the parameter values of the multiple channels are combined at least for a part of an audio frequency band in the parameter domain. The combined parameter values are then used for synthesizing the mono audio signal. The invention relates equally to a corresponding audio decoder, to a corresponding coding system and to a corresponding software program product.
