Patent DE-2624343-A1 (DE)
Title: Filter for dusty gases - with series modules each having falling sand curtain as filter medium
Inventor: GEIGER FRANZ ING GRAD
IPC: B01D46/34
Filed: 1976-05-31
Abstract: A gas filter module has a curtain of falling sand or quartz particles of size 1-4mm as filter medium. The module is used for the continuous filtration of dust-laden gases partic. at high temp. e.g. =750 degrees C. Compared with filters having static packed beds of sand, this construction gives a lower and constant press. loss and allows the use of gas velocities in a higher range e.g. =2-6m/s thus reducing equipment size.

Title: Regeneration of activated carbon - by indirect contact with heat transfer medium having system for optimum heat usage
Inventor: NOACK ROLF DR ING
IPC: B01J20/34
Filed: 1976-09-10
Abstract: Process for desorption and regeneration of activated carbon granules is carried out in plant with vertical passages down which the granules flow by gravity and having a heat transfer medium in cross flow on the outside. The device is separated into a series of heat transfer zones. In these the carbon is successively preheated and then heated up to the desorption or regeneration temp. It is finally cooled. The heat-transfer fluid is heated in an extremal heater. When it leaves a zone in which it is giving up heat to cooler granules, it passes on to zone where it picks up heat from hot granules and in this way cools them. It flows from the heater to the hot zone, then to the preheat zone and finally to the cooling zone. Alternatively, a separate fluid can be circulated round the preheat and cooling zones. Process is used for the regeneration of activated carbon on which a poisoning material has been deposited, esp. SO2. The system gives max. thermal economy and thus reduces the fuel required for the process.

Title: Textile strip delivery mechanism to conveyor - uses air jets with components in travel direction and towards edges
IPC: B65H23/24
Filed: 1976-10-22
Abstract: The mechanism delivers a moving strip of material esp. stiff textile strip onto a conveyor, having nozzles shortly before the transfer point. These discharge jets against the material, having a component towards the transfer point and in the travel direction of the material, while another component is directed towards the adjacent edge of the latter. A support and guide surface for the material can be provided on the opposite side to the nozzle, and sufficiently close to the conveyor for the intervening gap to be only slightly wider than the material thickness. The portion of the surface nearest to the conveyor can be hinge-mounted.
Patent DE-2655925-A1 (DE)
Inventor: SELD SIGURD
IPC: B02C4/32
Filed: 1976-12-09
Abstract: The device has a hydraulic force-generating device which serves to press the rollers (6, 8) together and has a pressure-force transducer (20). The working pressure space (30) of the transducer (20) is fed with hydraulic pressure medium via an adjustable pressure control valve (36) which determines the working pressure in the transducer (20). In addition, the working pressure space (30) is connected to a discharge line (34) via an adjustable pressure-limiting valve (28). The two adjustable valves (28, 36) can be coupled to one another in such a way that the respectively set nominal pressure of the pressure-limiting valve (28) is higher than the respectively set nominal pressure of the pressure-control valve (36) to such an extent that flowback via the pressure-limiting valve (28) does not take place under normal operating conditions. As a result, it is ensured that the hydraulic fluid does not have to be continuously circulated so that the power losses associated with it are eliminated. <IMAGE>

Title: Combined identifier and selective calling evaluator - compares received signal including start signal and check digit with stored identification signal
Inventor: DALLMANN HORST
IPC: H04W88/02
Filed: 1977-01-29
Abstract: A combined identifier and selective calling evaluator, esp. for radio telephony, generates a binary coded identification signal and compares it with a received selective calling signal which is part of a composite word frame including a start signal and a check digit. The incoming signal is fed to a first evaluator circuit, a second evaluator circuit and a first comparator which, together with an identification signal store are coupled to outputs of a timing circuit. The output of the identification signal store is connected to the second output of the comparator and with a unit for the formation of start and check digit signals. The arrangement generates a first indication if the selective calling signal corresponds with the identification signal and a second indication if they don not correspond.

Title: Satellite docking and stabilising control - uses controlled waveforms transmitted down link lines
Inventor: BSCHORR OSKAR DR ING
IPC: B64G1/64

Title: Laser extinction measuring device - measures high dust concentrations using laser beam and laser line filter removing extraneous light
Inventor: HOELTER HEINZ ING GRAD
IPC: G01N21/25
Filed: 1978-01-11
Abstract: The device measures dust content of gases in gas channels. It utilises the properties of a laser beam, such as high light intensity, small beam divergence and monochromatic light. It, therefore, makes possible direct and continuous measurement of high dust concentrations ingas channels with any desired dia. The whole channel dia. can be used for measurement even with large channels. The monochromatic light makes possible the use of a laser line filter, so that the device is very insensitive to generally disturbing external light.
