Title: Changeover valve for spraying jets - has ball closure in cylindrical chamber for changing pressure by tilting
IPC: B05B1/16
Filed: 1978-06-15
Abstract: The changeover valve is used for the pressurised jet of a liquid and air stream in a spray head with outlet nozzles. The pressurised jet is changed over from a relatively high pressure to a relatively low pressure jet. Large area covering spray is ensured at low pressure. The closing seats (6, 7) for the blocking elements are arranged in a chamber (12) below the supply channel (3) on the inlet openings (8, 9) of the nozzle. The supply channel (3) has additionally a positional safety element for the blocking element. The spherical blocking element is held in the cylindrical chamber and can be readily moved from one seat (6) to another seat (7) by tilting the valve chamber.

Patent DE-2835633-A1 (DE)
Title: Analogue picture formation system - uses letter printing mechanism with line indexing varied to form continuous curves which may be formed in both coordinate directions
Inventor: PICHL ORTWIN DIPL ING
IPC: G01D9/20
Filed: 1978-08-14
Abstract: The picture formation system uses a mechanism printing letters and numbers, particularly in a (7 x 5) pattern on metallised paper (2), for the simultaneous formation of analogue pictures such as curves and diagrams. The printing head slides across a paper support, which indexes for the desired line intervals. To produce an analogue picture, in place of the rigidly-defined line-indexing movement there is a variable feed mechanism (15). During picture formation this is changed over to an indexing feed movement corresponding to the vertical interval between the individual printing members, so that continuous curves can be formed in the direction of both coordinates.

Patent DE-2915968-A1 (DE)
Title: Hot gas filter - removes hydrocarbon(s) and dust by passing through moving horizontal bed of mineral particles
IPC: B01D53/06
Filed: 1979-04-20
Abstract: Hot gas flows with a bitumen and hydrocarbon content and laden with dust, e.g. from the reconditioning of asphalt courses, are purified by passing them through a continuously moving horizontal filter bed. An endless conveyor moves a filter bed of mineral particles across a filter chamber at an adjustable speed while the gases are passed across it. A pref. mineral matter are chippings which are used during the prepn. of the new asphalt road surface as aggregate. This prevents the rapid clogging of all filter media by bitumen and dust and recycles them in a satisfactory manner. The filter bed consists of chippings from standard road making material which can be controlled in height by the shutter and by the speed of the wire belt conveyor with its variable-speed motor.
