Patent DE-4026732-A1 (DE)
Inventor: MODIC RUDOLF
IPC: B01D53/72
Filed: 1990-08-24
Abstract: The invention concerns a process for purifying an oxidation waste gas evolved in a pressurized reaction process and laden with aliphatic and/or aromatic substances, with at least partial recovery of the energy contained in the waste gas. The waste gas stream is relieved in a relief turbine in order to generate mechanical or electrical energy. The waste gas to be purified is evolved, in particular, in an oxidation process with a gas containing oxygen, e.g. air oxidation of paraxylol (p-X) by the so-called Witten DMT process for producing dimethylterephthalate (DMT). According to the invention, the waste gas is burned under pressure and the flue gases produced are used to generate mechanical or electrical energy in a relief turbine. The process advantageously includes the following main steps: (a) partial condensation at approximately 35-60  DEG C of the substances to be removed by washing; (b) absorption with paratoluyl acid methyl ester (p-TE) or a mixture of p-TE and benzoic acid methyl ester (BME); (c) absorption with BME and/or methanol; (d) absorption with water; (e) combustion under pressure, possibly with a supply of oxygen and combustible products.

Title: Knitted fabric fault detection - registers reflection pulses to stop the knitter if pulses are repeated from same position on the material
Inventor: ROSENBAUM GERT DIPL ING
IPC: D04B35/20
Filed: 1990-12-14
Abstract: To control faults in knitgoods, produced by a knitter, the reflection principle is used with a constant and adjustable recognition sensitivity. A fault in the knitted piecegoods (1) is registered as a reflection pulse through a control unit (3) within an infinite number of separate steps, where the scanning stretch across the fabric width gives the location of the reflection pulses of a given scanning step. A fault seach field is formed within the scanning stretch for a freely selected number of knitting machine working cycles, and the given scanning step is inserted into the centre of an equal number of scanning steps. A fault tracking phase is executed, so that on achieving a freely selectable min. number of further detected reflection pulses, within the fault search field, the knitting machine can be switched off. Additional reflection pulses, outside an already opened fault search field, are processed separately and independently in the same way. The scanning steps are derived from an incremental unit coupled to the drive motor or gearing components which rotate in the same direction. ADVANTAGE - The system can observe a number of faults in the fabric, at the same time, independently of the knitter speed and external lighting, and the knitter is only stopped when a fault is repeatedly detected at the same spot in the material.
