Patent SE-512316-C2 (SE)
Inventor: GUSTAFSSON PER ERIK
IPC: B29C67/20
Filed: 1993-03-01
Abstract: The present invention is for method and means by the manufacture of a product of expanded polymer, by which is obtained a weight per unit volume which is essentially lower than that of homogeneous expanded material. The starting material for the manufacture of a product according to the invention can be either a specially manufactured starting material or scrap and recovered material. The pieces of expanded polymer are supplied in controlled quantities through a feeder (3) to a space (1) for the application of glue drops which are sprayed into the space from one or more dies (6). In the space (2) the pieces of polymer are dried by means of microwave energy which is obtained from an energy generator (9) and magnetrones (10). The dried pieces then are discarded from the space (2) together with the air flow through the opening (11). By the manufacture of a product according to the invention one starts from the pieces with glue applied to them as described above. The pieces are put into some kind of mould wherein they are pressed against each other. Thereupon the material is heated so that the glue becomes sticky and the pieces attach to each other. The heating is done by means of microwave energy which finds its way into and homogenously heats the whole volume of material. The method according to the invention makes it possible to manufacture products which retain their elasticity and have a weight per volume unit essentially lower than that of the starting material.

Abstract: In a method for signalling a noise substitution when coding an audio signal, the time-domain audio signal is first transformed into the frequency domain to obtain spectral values. The spectral values are subsequently grouped together to form groups of spectral values. On the basis of a detection establishing whether a group of spectral values is a noisy group or not, a codebook is allocated to a non-noisy or tonal group by means of a codebook number for redundancy coding of the same. If a group is noisy, an additional codebook number which does not refer to a codebook is allocated to it in order to signal that this group is noisy and therefore does not have to be redundancy coded. By signalling noise substitution by means of a Huffman codebook number for noisy groups of spectral values, which are e.g. sections made up of scale factor bands which do not have to be redundancy coded, an opportunity is provided to indicate the presence of a noise substitution in a scale factor band in the bit stream syntax of the MPEG-2 Advanced Audio Coding (AAC) Standard without having to interfere with the basic coding structure and without having to meddle with the structure of the existing bit stream syntax.

Abstract: The qualitative and/or quantitative gas analyzer uses a gas sensor with a predetermined heating cycle. The device has at least one chamber, containing a socket mounted sensor element which is receptive to a specific gas component and an apertured cover. The cover is rotatable relative to the sensor chamber, or vice versa, so that the aperture can be aligned with the chamber in order to expose the sensor to the test atmosphere for a predetermined interval. An independent claim is also included for the use of the analyzer in which conductivity-time profiles are measured for a particular component and compared with calibration profiles for various concentrations and conditions. The preferred detector devices are semi-conductors which may be used in conjunction with gas permeable filter membranes to provide gas specificity. The cover may be rotated by a stepping motor drive.
