Patent DE-3035926-A1 (DE)
Title: Weaving patterned fabric with variable weft density - by putting weft stop motion temporarily out of action
Inventor: NAMENYI PETER
IPC: D03D13/00
Filed: 1980-09-24
Abstract: During the formation of a woven fabric, the insertion of the weft is interrupted in predetermined zones, whilst simultaneously the weft stop motion is put out of action, to give a fabric having a patterned construction. As the sheeding of the warp threads is changed over, the weft stop motion is brought back into action, in accordance with the original programme. Zones having different, predetermined density of weft threads, with a variable intercrossing of warp and weft are thus obtd. Used for fashion or industrial fabrics having different and/or identical degrees of shrinkage and elasticity. Different densities of weft cancan be inserted without resort to complicated means of varying the let-off speed of the beam.

Title: Controlling feed rate of petroleum product - to double drum coking system, giving optimum coke prodn. in each drum
Inventor: BRUCE CHARLES R
IPC: C10B55/00
Filed: 1980-12-19
Abstract: The method of the invention is for predicting an optimal flow rate of petroleum into a coking drum during a coking cycle using a digital processing unit. It involves establishing a reference level in the coking drum and inputting petroleum into the drum. The presence of coke is also detected at the established reference level. Then the total quantity of petroleum inputted to the coking drum at the established reference level is automatically derived as is a petroleum flow rate for filling the coking drum to a desired capacity at the end of the coking cycle. The process control unit in combination with a conventional double drum coking system optimises the prodn. of coke in each of the drums since the appropriate coking process variables are continuously and automatically monitored and controlled.
Patent DE-3105720-A1 (DE)
Title: Flame tube boiler
Inventor: WIESER RUDOLF DR
IPC: F22B7/00
Filed: 1981-02-17
Abstract: The invention relates to a flame tube boiler having one or more pre-combustion chambers for the firing of coal dust or other barely ignitable fuels. The separate, double-walled pre-combustion chamber which is cooled by water and has an arched base and insulated inner surface makes it possible to form a rotating reversing flame and thus provides optimum preconditions for good ignition and complete combustion of the coal dust. The pre-combustion chamber is prefabricated in the factory and can be mounted - even subsequently -on the flame tube boiler in a short period of time. Already operating flame tube boilers can thus be converted from oil or gas firings to firings on coal dust. In terms of the fuel, this conversion not only increases the supply reliability, but also permits a reduction in fuel costs to be achieved since, nowadays, the heating cost of coal dust is considerably lower than the heating costs of heating oil or natural gas. <IMAGE>

Title: Construction system for, in particular, multi-storey buildings
Inventor: MENGERINGHAUSEN MAX DIPL ING D
IPC: E04B1/30
Filed: 1981-04-30
Abstract: The invention relates to a construction system for, in particular, multi-storey buildings with supports, crossmembers and floor panels, wall panels and ceiling panels or roof panels and/or unitised units. In the case of such structures known hitherto, complex foundations to be erected by means of in-situ concrete were necessary in order to absorb the vertical forces channelled away via the supports. The invention provides for the arrangement, on the outer periphery of the supports, of at least two force-channelling panels, parallel to the support axis and not located in one plane, such that the central planes of said panels cut the support axis, that the force-channelling panels are connected, by mechanical connecting means, on the crossmembers, prefabricated compound units and/or unitised units, and that, from the supports, crossmembers and prefabricated compounds units and/or unitised units provided with force-channelling panels, there is formed a lowermost unitised-unit slab which is stable in terms of statics and, instead of an in-situ-concrete foundation, channels away all the forces, acting vertically in the supports, downwards into the bottom of the structure and absorbs the moments from horizontal forces of any origin. The construction system according to the invention is mainly used in the construction of multi-storey residential buildings and functional buildings, e.g. schools and small hospitals (excluding high-rise buildings).
