Title: Tufting bar for holding row of tufting elements - secured by clamping screws in keyed groove in bar permitting replacement of individual elements
Inventor: DOERR HANS-JOACHIM ING GRAD
IPC: D05C15/22
Filed: 1980-05-20
Abstract: A row of needle, knife or gripper elements in a tufting machine is held in a bar having a longitudinal groove, perpendicular to the direction of production, to house the shafts of the elements. One of the faces of the groove has a longitudinal ridge or notch which engages a corresponding notch or ridge on the shaft, and in the opposite side of the bar are staggered rows of clamping screws, of which there is at least one to each element, to secure the elements in the groove.

Abstract: Method and unit for the irrigation of planted noise protection walls, roof plantings or delimitations of areas with constructions made of concrete, expanded concrete with no-fines texture, iron, steel, aluminium, plastic or wood. Noise protection walls which are partially planted are known. Unless it rains heavily, they must be irrigated. The method applied for dispenses with constant servicing. It allows planted walls to be erected at any desired site. An additional supply of water during dry periods is not necessary. Rock wool plates standing in the P.E. sack are arranged inside the free interior of the construction of durable material in such a way that they form a 10 cm thick wall along the longitudinal axis of the construction (drawing 2). This rock wool wall absorbs 85% of its volume of water. Together with the P.E. sack, it forms a sort of water container. The humus soil and therefore the plants are supplied with water via bundles of capillaries, or directly in the area of the free part of the rock wool plate. The interior of the construction is filled with humus. The compost is held by means of support boards (drawing 2). After planting, the water supply flows in the direction of the small arrows and ensures the growth of plants in the noise protection wall. <IMAGE>

IPC: F23C10/00
Filed: 1981-11-28
Abstract: The fluidised-bed coal firing for rotary kiln drying installations is to be improved in such a way that shut-downs, which unexpectedly become necessary, of the rotary kiln cannot lead to local overheating and distortions of the rotary kiln, which are to be ascribed to the fluidised-bed coal firing which still continues to run for a short period - up to eight minutes. This is achieved by heat-resistant water addition nozzles which are arranged in the reaction chamber of the fluidised-bed coal firing or in the hot gas entry zone of the rotary kiln and which release water after the coal dust feed has been switched off.

Title: Process for producing porous mouldings of polycrystalline boron carbide with self-bonding by pressureless sintering
Inventor: KRIEGESMANN JOCHEN DIPL ING DR
IPC: C04B38/00
Filed: 1981-12-16
Abstract: The invention relates to a process for producing mouldings of boron carbide, wherein boron carbide powder having a bimodal grain size distribution is precompacted from a coarse grain and a fine grain fraction without additional use of sintering aids to form green contacts and is then sintered without pressure at temperatures between 1900 DEG C and 2150 DEG C in the presence of a blanketing gas atmosphere. The mouldings thus obtained are polycrystalline and porous, and have a uniform grain size distribution and pore distribution. Their density is fixed by the density of the green contact, since only a very slight shrinkage of at most 1.5 % or virtually none at all takes place during the sintering step, and they have a flexural breaking strength from at least 100 up to about 200 N/mm<2>.
