Title: Method and installation for the preparation of packaging materials containing fibres
Inventor: BAECHLE VOLKER
IPC: D21B1/02
Filed: 1993-05-03
Abstract: Method and installation for the preparation of packaging materials containing fibres, in particular of so-called Tetra-Packs, the packaging surface first being roughened. The fibres are next broken down in a container (4) which is filled with water. Finally, the fibres are separated out from the remaining components of the packaging by means of tumbling and finally separated. The method can be carried out in a particularly advantageous manner by using a novel tumbling tube (61). Within the tumbling tube (61), a flexible tube (62) is arranged continuously coaxially in such a manner that an annular space (63) is formed between the inner wall of the tumbling tube (61) and the tube (62). The annular space (63) can be repeatedly cyclically exposed to compressed air via valves (65). The water, with the components of the packaging dispersed therein, is fed through the interior of the tube (62). During the passage through the tube (62), the components of the packaging are tumbled many times as a result of the contraction of the tube (62). By this means, the fibrous components can be separated carefully and without mechanical damage from the composite material. <IMAGE>
Patent DE-4315278-A1 (DE)
Inventor: SCHMELZ HELMUT DIPL PHYS DR
IPC: F01N3/20
Filed: 1993-05-07
Abstract: A method for the controlled introduction of a reducing agent into a nitrogen oxide-containing exhaust gas leaving an internal combustion engine through an exhaust line having a catalytic converter built in for reducing nitrogen oxide, includes detecting at least one operation-relevant parameter of the exhaust gas, of the catalytic converter and optionally of the engine to determine the nitrogen oxide rate. An intermediate value is determined for the reducing agent rate as a function of the nitrogen oxide rate. The intermediate value is reduced by a rate of the reducing agent desorbed by the catalytic converter or raised by a rate of the reducing agent adsorbed by the catalytic converter. An apparatus for performing the method includes a control unit. A device detects at least one operation-relevant parameter of the exhaust gas, of the catalytic converter and optionally of the engine. A reducing agent supply unit introduces the reducing agent into the exhaust line upstream of the catalytic converter. The control unit is intended to adjust a rate of the reducing agent introduced into the exhaust gas as a function of the parameters, while taking into account a rate of the reducing agent adsorbed by the catalytic converter or desorbed by the catalytic converter.

Title: System for obtaining pork
Inventor: SEIDEL BERND DR SC TECHN
IPC: A22B7/00
Filed: 1993-05-21
Abstract: The invention relates to a system for obtaining pork. The aim of the invention is the maximum reduction of the number of personnel needed for roughly cutting up halves of pigs compared to systems in use at present. The object is achieved in such a manner using analogue technology that the suspended halves of pigs are positioned. The positioned halves and parts thereof then pass cyclically along the active configuration-measuring conveyor, through the head-separating device, the front leg-separating and flank preseparating device, the punching station for the front leg, the punching station for rough cutting up, the haunch cutting-up device and the cutting-up belts. Figure 1 explains the invention. The baffles 4 position the halves 1 and 2. The displaceable baffle conveyor 5 moves the halves to the active configuration measuring conveyor 10. This results in the arrangement of the head-separating device 16, the front leg-separating and flank preseparating device 19a, the punching station 26a for the front leg, the punching station 26b for rough cutting up, the haunch cutting up device 44 and the conventional cutting-up belts 46. <IMAGE>

Title: Method for cutting back a loosely buffered fibre
Inventor: BOEHME RALPH DIPL ING
IPC: G02B6/245
Filed: 1993-07-27
Abstract: In a method for cutting back a loosely buffered fibre (1) which comprises a small metal tube (3) with at least one optical fibre (5) extending therein, such as are used, for example, in earth cables or aerial cables, the wall thickness of the small tube (3) is reduced at a cutting-back point (7) by the removal of material. In the longitudinal direction of the loosely buffered fibre (1) and at a distance to the cutting-back point (7), a bead (11) which points inward in the radial direction is formed in a section (9), which is to be removed, of the small tube (3). The small tube (3) is now severed at the cutting-back point (7) and the section (9), which is to be removed, of the small tube (3) is drawn off over the at least one optical fibre (5) (Fig. 1). <IMAGE>

Title: Volume-flow regulator (controller, governor) for pneumatic conveyance of solid matter
Inventor: FELDHAUS BERND
IPC: G05D7/00
Filed: 1993-08-11
Abstract: Overpressure conveying systems transport solid matter by expansion of compressed air. For reasons of operational reliability, a high flow rate is frequently employed, which has the result that the conveying time, the pipeline wear and the energy consumption are unnecessarily high. The invention relates to a device which, without external energy, creates a closed-loop control circuit which optimally counteracts the abovementioned negative factors. The volume-flow regulator (1) exhibits, with its oversized working piston, an essential feature. Through the pressure regulator (2) with secondary relief, a constant pressure (e.g. 1.5 bar) is transmitted onto one working-piston area, which moves the volume-flow regulator into the normal "open" position and releases a maximum flow of solid matter. If the quantity of transporting gas, regulated in quantity by a valve (3), allows approximately 1.8 bar to act on the other piston area via a filter (4), the volume-flow regulator moves into the "closed" direction as a result of the blowing-off pressure regulator (2) and thus reduces the supply of solid matter until an equilibrium is established. The volume-flow regulator can optimise any kind of solid matter conveyance and is used on all movable and fixed pressure conveying vessels. <IMAGE>

Title: Hose-connection device
Inventor: WIECZOREK EDWARD
IPC: F16L19/065
Filed: 1993-09-01
Abstract: Relatively rigid hoses are not suitable for being pushed directly onto connection pipes. Tapered-ring screw connections which are suitable for this purpose are expensive. The hose-connection line according to the invention has the features that a tapering (5) and pressure-exerting ring (9, 17) are retained in captive fashion by a termination ring (8) inserted in the receiving bore (3), that the pressure-exerting ring (9, 17) projects outwards through the termination ring (8) and has a collar (11) there, that, by axial loading of the collar and adjustment inwards or outwards, the hose (15) is fixed or released, and that an elastomer ring (14) is inserted between hoses (15) and receiving bore (3). As a result, rapid hose mounting has become possible. <IMAGE>

Title: Method and system for storing thermal energy (heat energy)
Inventor: BACHERT HANS-JUERGEN DR
IPC: F25B17/08
Filed: 1993-09-30
Abstract: The present invention relates to a method and a system for storing thermal energy, chiefly as solar energy, by means of a thermal energy reservoir which alternately absorbs thermal energy with the aid of a heat carrier (heat-carrying medium, heating medium), and also gives it off again via said heat carrier. The method is characterised in that, in a manner temporally coupled to the supply of thermal energy, the heat carrier gives off thermal energy to a preferably thermochemical storage material in which the thermal energy is used for desorption of a working medium, and in the reverse case of the sorption of the gaseous phase of this working medium is given off again to the heat carrier.

Title: Compact baffle grid assembly redirects gas and particle flow downwards
IPC: F23J3/04
Filed: 1993-12-24
Abstract: An assembly separates particles or droplets from heterogenic (dispersed) fluids such as suspensions, spray or dust, esp. large particles from a gas. The novelty is that the dispersion phase carrier medium passes through a baffle grid which imparts a downwards flow direction towards the particle collection zone. The baffle grid is enclosed at the rear and sides to form a shaft. The particles are removed at different points within the shaft cross-section. The baffles may be of different shape and their position settings may be tilted as required.
