Title: Air-jet loom with two=part constrictors - which separate on beat-up to permit shortened sley movement
Inventor: SCHEFFEL WALTER
IPC: D03D47/30
Filed: 1979-01-15
Abstract: Constrictors of an air-jet loom are in two sections, comprising lower plates fixed to the sley and upper plates, not co-planar with the lower ones, mounted independently so that the paths of the upper edges of the two sections intersect as the sley moves towards beat-up and at beat-up the upper plates are closer to the pivot of the sley than they are at weft insertion. Action of the two-part constrictors allows a shorter sley movement, and hence a smaller shed to be employed, permitting higher weaving speeds. At the same time, stresses and abrasion are diminished and energy consumption and noise prodn. are reduced.

Title: Conveyor in chipboard prodn. - where wire carrier lengths on slats pass near sprinkler to ensure accurate chips orientation
IPC: B27N3/14
Filed: 1979-05-12
Abstract: In the prodn. of chipboards etc. the particles sprinkler is stationary, the feeder system has two parallel synchronised chains with flexible conveyor e.g. wires which lie on slats and have crossbars projecting at their ends. Feeder is linked to the conveyor whose slats are fixed n the parallel chains, there are gaps in the slats at intervals depending on the length of the conveyor wires, crossbar stops fit into these gaps underneath the conveyors and also project at the ends. Sprinkler system does not upset orientation of the particles because it is close to the conveyor wire and the gap is not affected by the crossbar stops.

Title: Water purificn. by ozone - through side stream for contact with oxygen recycled via nitrogen adsorber and ozoniser
Inventor: BERGER MICHAEL DIPL CHEM DR RE
IPC: C02F1/78
Filed: 1979-12-11
Abstract: In a water purificn. system by an ozone treatment, a side stream is purified by absorption of ozone in a contact reactor from an ozoniferous oxygen stream which absorbs the released nitrogen and is returned to an ozoniser for recycling to the contact reactor. Before the oxygen stream enters the ozoniser, a controllable amt. of the absorbed nitrogen is extracted by adsorption. A pipe passes 1000 cu.m/h raw water through a reaction stage which also receives a side stream of 20 cu.m/h from a pump via an ozone enrichment washer. A pipe circulates ozoniferous oxygen. The gas leaving contains 86 vol.% oxygen, 12.4 vol.% nitrogen and 1.6 vol.% water vapour. After passing through a dryer with silica gel filled absorbers, a 10% side stream is passed through an adsorption plant, i.e. zeolitic molecular sieves, for 100% nitrogen adsorption. Pure oxygen is added from a pipe downstream of the bypass line to make up the oxygen loss. This system reduces the costs for investment and for operation to a min.
