Patent DE-4244270-A1 (DE)
Inventor: UNO TADAO
IPC: B65G57/03
Filed: 1992-12-28
Abstract: A plurality of parallel sheet-bundle piling lanes 10 are fed by a common sheet-bundle feed lane 43 for gradually feeding sheet-bundles 8. At a communicating portion between the sheet-bundle feed lane 43 and each sheet-bundle piling lane 10, a sheet-bundle take-in lever 46 for taking the sheet-bundles 8 from the former lane to the latter lane is disposed. In each piling lane 10, an upper table 21 supports a series of sheet-bundles 8 but can be opened to allow each bundle to fall onto a respective pile 11. A lower table 31 supporting each pile 11 is lowered as the pile accumulates. Pushers 45, 28 and 34 propel the sheet-bundles 8 and the completed piles 11 respectively. Each bundle 8 is bound by binding 7 and the completed piles 11 are bound by binding 12, 13. The sheets are arranged in serial number order and may be banknotes, lottery tickets or postcards. <IMAGE>
Patent DE-4302189-A1 (DE)
Inventor: BEZLER WILHELM DIPL ING
IPC: B41F13/02
Filed: 1993-01-27
Abstract: The speed of a motor 8 driving a web traction roll 120 is controlled in dependence upon the sensed angle of an arm 106 carrying a jockey roller 100, the tension in the web 140 thus being regulated. A computer control system can set the desired value of web tension, via a signal to pneumatic cylinder 105, and set a nominal speed for motor 8. The system receives a signal representing the angle of arm 106. Traction roller 120 is provided with devices (figure 4) for sensing web wrapping around the roller, as it might after a tear. The motor 8 is stopped and cutting devices 145 and 146 are operated if such wrapping is detected. <IMAGE>

So that the stroke movement of the pin (2) is converted to a circular movement of the pressure indicator.The pressure pin (2) and the housing (1) are designed cylindrical in shape and guide bushes (9) are provided, which guide the pressure pin in its stroke movement, axially and centrally in the housing (1) and the O-rings in the bushes provide the sealing between pin and housing.
Patent DE-4303240-A1 (DE)
Title: Method for regulating pressure in hydrostatic drive systems
Inventor: STRENZKE HILMAR DR ING
IPC: F15B21/08
Filed: 1993-02-04
Abstract: In a method for regulating pressure in hydrostatic drive systems, the feed volume of a variable-displacement pump (1), by which a variable-displacement motor (2) is driven, is reduced, when a specific pressure level is reached, to a value which guarantees that the pressure level is maintained. It is proposed permanently to determine separately by means of an electronic module (7) the volume flows generated by the variable-displacement pump (1) and received by the variable-displacement motor (2) and to compare them with one another. Insofar as different volume flows occur, this is a signal that the permissable operating pressure is exceeded and pressure medium flows off via pressure-relief valves (4, 5). The feed volume of the variable-displacement pump (1) is therefore reduced by means of signals from the electronic module (7), until the volume flows are approximately equal. The volume flows of the variable-displacement pump (1) and of the variable-displacement motor (2) are determined indirectly by measuring the drive speed of the variable-displacement pump (1), the setting of the feed volume, the speed of movement of the variable-displacement motor, the setting of the absorbed volume and subsequent calculation. The advantage is that an otherwise conventional hydraulic pressure cut-off is avoided. <IMAGE>

Title: Binding heavy metal residues in ceramics - by moulding mixt of silt, water and e.g. electroplating sludge then firing
Inventor: BENDER ALBERT DIPL ING
IPC: C04B33/16
Filed: 1993-11-10
Abstract: Prepn. of ceramic bodies, in which heavy metal-contg. residues (HMR) are bound, comprises: forming a mouldable mixt. contg. HMR, water and silt; moulding a green body from the mixt.; and firing the mixt. to give a dense, sintered, stone- or brick-like body. Alternatively, a mixt. contg. HMR and silt is pressed and fired to give a prod. as above. Ceramic bodies obtd. by the process are also claimed. USE/ADVANTAGE - HMR are esp. hydroxide sludges, specifically from electroplating plants, chemical pptn. or dissolution processes or waste water purificn. plants (all claimed). Such materials are utilised and made harmless in ceramics, from which heavy metals are not, or only very slowly, eluted. Silt contaminated with harmful organic components (e.g. mineral oils or polychlorinated biphenyls) can also be disposed off, as well as other problem materials (added to the ceramic-forming mixt.) such as glass grinding sludges (e.g. as waste from the glass or enamel industry), used casting sand and blasting sand, dust from dry separators (e.g. waste gas purifying filters) and fly ash. The process uses silt, rather than (more expensive) clay. In some cases addn. of flux is unnecessary, since hydroxide sludges can act as flux.
