Title: Method for the production of a fuel gas for burning in a combustion chamber
Inventor: LEIBRANDT GEORG DR
IPC: F02C3/28
Filed: 1993-03-06
Abstract: A fuel gas, which has previously been burnt in a combustion chamber, is added to a combustion gas produced in a pressure firing system in order to increase the temperature to more than 1150 DEG C. The fuel gas is produced by low-temperature carbonisation of fine-grained coal in a combustion reactor heated by the pressure firing system. The coal is pneumatically fed to and through the combustion reactor by means of the combustion gas, which has previously been compressed to a higher pressure. The flow of coal and combustion gas, controlled in an adjustable throttle cross-section, is expanded to a lower pressure before entering the combustion reactor.

Title: Method and installation for working frame-wood members for window frames
Inventor: HIRSCH WILHELM
IPC: B27M1/08
Filed: 1993-03-31
Abstract: In a method for working frame-wood members for window frames, one frame-wood member or a pair of frame-wood members is moved from a starting position transversely to its longitudinal direction in a first movement region past end-working tools into an end position and during this process is mortised (slotted) at its respective first end. It is then taken directly from its end position into a region outside the first movement region, turned through 180 DEG  without interposition of a further working operation and then taken back into the starting position or the vicinity thereof. While this is taking place, a further frame-wood member or pair of frame-wood members is moved in the first transverse-movement region past the same end-working tools and provided with mortises. Subsequently, the first pair of frame-wood members is moved a second time past the same end-working tools and during this process mortised at its respective second end, and finally each frame-wood member is moved in its longitudinal direction along longitudinal-profiling tools and during this process profiled on at least one longitudinal side.

Title: Piston of two-part design for extreme stresses
Inventor: BRAUNGARTEN GUNTER DIPL ING
IPC: F16J1/00
Filed: 1993-05-19
Abstract: The invention relates to a piston of two-part design for extreme stresses. To reduce thermal loads in conjunction with an improved build-up of lubricating film on the cylinder wall, even in the case of high mean pressures, and to avoid sticking of the rings and reduce costs, the piston is characterised in that the first ring land has a height of about 6% to 14%, preferably 10%, of the piston diameter and is provided with a shape curve which is determined by the characteristic of the temperature gradient across the height of the first ring land.   In addition, the oil-collecting grooves, situated on the inside of the slider surface, for the coolant and/or lubricant are arranged with their feet above a cylinder plane drawn through the centre of the hinge-pin bearing. There is only one spray nozzle for spraying the piston. At the upper edge of the outer surface, the slider has a chamfer in a range of from 10 x 15 DEG  to 15 x 15 DEG . The second ring is configured as a simple rectangular ring.

Patent DE-4324612-A1 (DE)
Title: Room-enclosing wall structure for a building
Inventor: WILZ HUBERT
IPC: E02D27/30
Filed: 1993-07-22
Abstract: Instead of the conventional solid construction method involving an extremely high degree of outlay, use is made, for the exterior wall of a residential building, of a wall structure in which the load-bearing wall element is a steel sheet-piling wall anchored fixedly to the base of the residential building. A retaining system has preferably already been fitted on the steel profiles of the steel sheet-piling wall at the factory, which retaining system serves for the fixed connection to the claddings of the wall structure itself and/or other structural elements of the building, for example ceilings. The retaining system thus makes it possible to provide a fixed connection, above the base of the building, of further reinforcements to the steel sheet-piling wall, which reinforcements, at the same time, also prevent the steel profiles of the steel sheet-piling wall from spreading apart outwards. Using the steel sheet-piling wall makes it possible to restrict excavation to the actual area used for the lowermost storey, and there is no need for any barrier (insulation) against ground moisture and the penetration of water since the steel profile can have water-tight connections. Furthermore, with a suitable selection of profiles, the steel sheet-piling wall permits great advantages for the interior installation as a whole, and there is a large amount of space available for insulating material.

Title: Dental articulator
Inventor: SCHREIBER HANS DR DR
IPC: A61C11/02
Filed: 1993-08-19
Abstract: There is proposed a novel dental articulator whose essential component is a side shift adjustment means which is released in a defined manner (15) and pivots back via a spring mounting into the starting position. At the same time, it must be emphasised that the guide element (20) ensures free viewing of the condyle ball (2) due to the open condyle element (8). This is impossible with the conventional articulators. Moreover, the element (19) makes it possible to carry out a proper retrusion movement. It is, of course, possible for the guide elements (20) to be produced individually. <IMAGE>

Patent DE-4421843-A1 (DE)
Inventor: SYKORA JUERGEN
IPC: H01L21/306
Filed: 1994-06-22
Abstract: The present invention describes a process and a device for removing particles from objects, especially as an alternative to ultrasonic or chemical cleaning. The objects to be cleaned are inserted in a process chamber (14) which is closed by a plate (24). The objects (18) are then moistened by a wetting device (42). The process chamber is then evacuated until the moisture on the objects has become ice. The ice coating is liquefied again by repressurising the chamber. The particles are easily removed from the surface of the objects by this step in the process. This process for removing particles optionally comprises a subsequent drying process. It is environment-friendly and suitable in particular for highly sensitive objects.

Title: Slatted base for furniture on which to lie
Inventor: ERBE GUNTRAM
IPC: A47C23/06
Filed: 1994-09-09
Abstract: In known slatted bases, the upper slats are assigned lower slats which prevent the mattress from sagging. In this case, the upper slat deflects in a first bending region on its own and in a second bending region together with the lower slat. By means of the slatted base according to the invention, a high degree of lying comfort is achieved at reduced production cost. For this purpose, the upper slats (1) consist of profiled bars which are open at the bottom, are U shaped, are curved upwards and are made of fibre-reinforced plastic. The lower supporting slats (4), which consist of straight profiled bars with approximately rectangular cross-section, are arranged therebelow, plunging from below into the upper slats (1). As a result of this configuration of slats and supporting slats, a very high degree of adaptation during deflection is achieved, without complicated, laterally tiltable slat holders being necessary. <IMAGE>
