Patent DE-4205792-A1 (DE)
IPC: G01N1/24
Filed: 1992-02-26
Abstract: The invention concerns a process and a device for taking samples in particular from waste gases containing substances of moderate and low volatility in a gas or aerosol phase. To this end, partial current is diverted and conducted into a separation area, where the substances to be tested from the partial current, either in dust-bonding form or in the condensate, undergo a separation process and are fixed. When applied to a specific sample for the analysis of organic substances of medium to low volatility, in particular polychlorinated dibenzo (p) dioxins (PCDD) and polychlorinated dibenzofuranes (PCDF), the separation process can be restricted according to the invention in such a way that the partial current, together with the gaseous and liquid water portion contained in it, undergoes a two-stage separation process, where it is drawn through an inert dust-filter region, and drawn through a region filled with an adsorber such as a synthetic adsorbent resin with a multi-reticular structure. The gaseous water contained in the waste gas is not removed before being drawn into the adsorber region, nor is the dew point lowered by dilution.

Title: Cross cutting machine for continuously moving soft e.g. clay tubing - has four pneumatically operated radial cutter blades which move together with emerging tubing and cut through quadrants at length required
IPC: B29C48/25
Filed: 1992-05-13
Abstract: A machine for cross-cutting a continuously moving soft and plastic material, particularly a tube of clay or similar, has a cutter which advances at the same speed as the moving material and in the same direction. The cutter is moved by the material itself. Pref. the emerging tubing (12) is cut by a system mounted so as to move along a track (19). The tubing (12) passes out inside a ring (21) which has four freely revolving guide rollers (23). A ring (25) turns in the annular space (26) between the extrusion (12) and the hole (22) in the ring (21); it is driven (28) to and fro (29) by a cylinder (33) and arm (31). Four pneumatic cylinders (35-38) have pistons (43-46) attached to cutters (39-42). When a length of extruded material has emerged and reaches the cutters a sensor triggers the blades and the whole cutter system advances with the tubing (12); at the same time the cylinder (28) drives the cutters (39-42) through a quarter-circle and they hence cut through the complete tubing. The system then reverses for the next length. ADVANTAGE - The machine cuts lengths of the material without damaging it. It requires only very simple controls.
