Inventor: BERGER BEAT GUENTER
IPC: B01D29/11
Filed: 1993-04-20
Abstract: Le filtre à mazout échangeable destiné à être monté dans un dispositif de filtrage placé dans la conduite d'arrivée de mazout d'un brûleur à mazout présente un élément de filtrage poreux cupuliforme constitué de particules de polyéthylène frittées ainsi que d'un élément de fixation en polypropylène de forme sensiblement annulaire et relié à l'élément de filtrage. L'élément de fixation annulaire est relié uniquement à l'extrémité de l'élément de filtrage cupuliforme, sans s'engager dans celui-ci, du fait qu'à la surface de jonction des deux parties, les matériaux de ces deux parties sont partiellement fondus entre eux et/ou que le matériau de l'élément de fixation pénètre en partie dans les pores de l'élément de filtrage poreux. Le filtre à mazout est réalisé en une seule opération par un chauffage commun des granulés en polyéthylène et en polypropylène dans un moule en céramique au moyen de micro-ondes.

Patent WO-03039157-A1 (WO)
Inventor: SAAR EVA
IPC: H04N19/467
Filed: 2002-09-20
Abstract: The invention relates to a method for attaching an information-coding digital watermark to a time sequence of individual digital images (image sequence), in particular to a video film or video film sequence. According to said method, a digital and acoustic signal (sound sequence), which varies over time, can be associated with said time sequence. Said image sequence is divided into partial sequences, which comprise several individual images. Within one partial sequence, a parameter, which is immanent to said image sequence and/or associated acoustic signal, is modified in relation to the original, which is to be marked. The modified parameter is maintained over the total partial sequence and the information is coded in the sequence of the parameter modification, which varies from a partial sequence to another.

Title: Skin turning for flesh stripping machines - by moving suspension tackle along adjoining parallel paths
Inventor: ZAEPFEL HORST
IPC: C14B1/00
Filed: 1973-05-19
Abstract: The flesh from skins is normally stripped in two operations, each treating one half of the skin only. To turn the skin mechanically after the first half has been stripped, the skin is suspended from a twin chain conveyor on suspension tackle. The turning operation is done by advancing the suspension tackle on one chain far enough to turn it through nearly 180 degrees. The following stripping machine then receives the skin with the untreated half leading. This saves the extremely heavy labour required for turning the wet skins of large animals. It is also suitable for machines which do not operate on the flow line principle.
