Title: Method for the regeneration of particle filter systems
Inventor: BERENDES HEINRICH
IPC: F01N9/00
Filed: 1993-02-09
Abstract: Proceeding from a method for the regeneration of particle filter systems for the exhaust gases of diesel internal combustion engines, a burner system being operated at least as a function of the exhaust gas back pressure during a certain period (regeneration) in order to burn off the soot particles in the exhaust gas flow deposited in a particle filter, and it being possible to operate the burner system for regeneration only once a value representing a stable operating condition of a diesel internal combustion engine has been attained, the object on which the invention is based, to improve known methods in such a way that the temperature at the particle filter inlet is kept as constant as possible during regeneration at a value predeterminable as a function of system variables of the particle filter system and/or of operating variables of the internal combustion engine, is achieved in that before regeneration commences a value for the exhaust gas back pressure is registered and compared with a value, inferable from performance characteristics, which as a function at least of system variables of the particle filter system and/or operating variables of the diesel internal combustion engine corresponds to a value for a charged or uncharged particle filter, and is implemented as a function of the result of that comparison in order to keep this variable as constant as possible. <IMAGE>

Title: Method and apparatus for cutting a brittle body with laser radiation
Inventor: BOLLMANN DIETER DIPL PHYS
IPC: B23K26/06
Filed: 1993-02-19
Abstract: The cutting of brittle bodies, in particular hollow bodies or plates, for example of glass or ceramic, is widely used in technology. In hitherto known laser-cutting methods, in each case a mechanically complicated movement of the laser beam relative to the body is necessary. In the method described here, the body to be cut is heated at the surface along the cutting line by the action of the laser beam in such a way that a thermo-mechanical stress builds up which leads to the fracture of the body to be cut at this cutting line. According to the invention, the laser beam is projected with suitable focusing optics onto the surface of the body in such a way that it irradiates the entire cutting line at the same time. The development of the fracture is assisted by modulating the irradiated laser intensity with respect to time. With the use of an annular mirror arrangement, the method described can be used, for example, for cutting off the pressed margin of drinking glasses.

Title: Device for detecting the overfilling of an overflow channel for liquids
Inventor: ROSBERG RAINER DIPL ING
IPC: G01V8/14
Filed: 1993-02-26
Abstract: In channels of very small cross-section it is difficult to detect various filling levels, since the differential pressure available for the measuring process is very small. By means of the novel device, the filling level in a small, preferably capillary, volume chamber is intended to be measurable. Provision is made of a liquid channel (4) and of an overflow channel (5) connected to it in terms of fluid and partially delimited by a plate (9) consisting of transparent material, the channel (5) having allocated to it a transmitter (7) for light and a receiver (8) for this light, the plate (9) making possible a total reflection of the light emitted by the transmitter (7), which light then reaches the receiver (8). A comparator for forming an evaluable measuring signal is connected downstream of the receiver (8). The device gives good measurement results with all liquids, including coloured ones. It is constructed in a compact manner and is insensitive with respect to externally acting influences. <IMAGE>

Title: Equipment group for pumping out oil, fuel and liquids in ships in distress
Inventor: ROSENBROCK KARL-HEINZ
IPC: B63B27/24
Filed: 1993-04-01
Abstract: In the case of ships in trouble, every salvage crew must first reach the ship, whether from a salvage vessel or from the shore. The attempt often fails because of the weather. In a heavy storm, the attempt to pump out oil, fuel or other liquids still present is not made at all. Oil, fuel and other liquids can be salvaged by the equipment group even in bad weather, storms and hurricane-force gusts. This can also be done from the shore or if the ship's tanks are below the water surface without having to go aboard the ship in trouble. If a ship (1) gets into distress, the duty of the crew is to cast the hose drum (4) overboard from the device (2) by means of a hydraulic system (12). The salvage vessel (8) called in can then quickly attach its suction hoses (5), carried by air cushions (6), to the hose drum (4) and the pumping-out can begin. Can be used in all ships even in inland waterways. <IMAGE>

Abstract: PCT No. PCT/EP94/01152 Sec. 371 Date Dec. 12, 1995 Sec. 102(e) Date Dec. 12, 1995 PCT Filed Apr. 14, 1994 PCT Pub. No. WO94/25509 PCT Pub. Date Nov. 10, 1994Described is a method of extruding a cross-linked polymer, the method calling for the polymer to be cross-linked to be extruded in granular or powder form with liquid additives. The method is characterized in that a granular or powder-form polymer with a fissured, porous surface is used. This granular/powder-form polymer with an irregular surface structure is fed through a feed line to a mixing zone by injecting at least one liquid cross-linking additive and subsequently extruding the mixture in an extrusion press. Obtained during this extrusion is improved distribution of the liquid over the polymeric particles, more uniform grafting of the cross-linking agent on to the polymer and hence, a homogeneously cross-linked product.

Title: Fermentation process for the continuous production of citric acid
Inventor: ANASTASSIADIS SAVAS
IPC: C07C59/265
Filed: 1994-03-07
Abstract: In the continuous production of citric acid by fermentation using yeasts, in particular of the genus Candida, a C/N ratio in the feed stream corresponding to 12-22, in particular 15-18, mole of glucose per mole of ammonium compounds is used with residence times between 60 and 120 h and glucose concentrations in the feed stream of 100-400 g/l. The atmospheric oxygen saturation in the fermenter is expediently set at 15-30%, in particular about 20%. The N concentration in the feed stream is, in particular, 50-150 mM. A C source concentration corresponding to > 200 g/l glucose in the feed stream is beneficial. pH values between 4 and 5.5, in particular around 5.0, are very suitable, and the temperature is, in particular, between 29 and 31 DEG C. Apart from the traces of iron in the  mu M range present in the medium, it is expedient to add no iron. The content of zinc, manganese, copper and magnesium ions depends on the N concentration and is optimised. Good results are obtained in continuous flow fermenters with biomass retention and unsupported yeast.

IPC: B29C65/34
Filed: 1994-11-23
Abstract: Thermoplastic moulded parts (5) may be joined by means of metal strips (3) provided with a plurality of pins (1). In order to anchor the metal plate in the plastic moulded part in a solid manner, the metal strips (3) are heated above the softening point of the plastic material and the pin-bearing side of the metal plate is then pressed into the plastic material (5). These metal strips (5) may then be at least partially embedded in an adhesive or filler layer. This process is particularly suitable to improve damaged plastic moulded parts, in particular car parts, such as fenders or projector housings. The moulded parts repaired by this process recover their original performance capabilities, in particular their dimensional stiffness, their shock-resistance and their visual appearance. When the thus repaired moulded parts are scrapped, they may be entirely recycled by the usual methods.
