Title: Gas pressure reducing valve - uncouples from diaphragm and shuts under excess pressure
Inventor: SCHLADERER MAX
IPC: G05D16/06
Filed: 1990-10-31
Abstract: The gas-pressure-reducing valve comprises a housing (1) divided by a diaphragm into governor-spring and regulation chambers (3,5).  The latter has a union with valve (10) for the feed pipe (6), also one for the discharge pipe (7). The valve moves on and off a seal (8) under the effect of movement of the diaphragm (2), which is transmitted to it by a mechanism (11-22) and generated by the opposing pressures of the regulation chamber and governor spring (4). Pressure above a first threshold value holds the valve against this seat, while below a second threshold value the valve is held against a secondary seat (9), and it is open in the intermediate position. The mechanism includes means (17, 18, 22) for uncoupling the diaphragm from the valve when a third and highest threshold value is exceeded, whereupon the valve is pressed against the secondary seat. USE/ADVANTAGE - Fully protects any units connected to discharge pipe against excess pressure.

Patent DE-4114042-A1 (DE)
Inventor: DITTMANN GUENTER DIPL ING
IPC: F27D15/02
Filed: 1991-04-29
Abstract: The invention concerns a device for heat treatment of bulk materials, in particular a cooling device for cooling cement klinker from a furnace comprising a materials transfer device in a region below the furnace outlet and through which cooling gas passes, associated with an ordinary grate cooler which conveys the materials to be cooled. The invention proposes that the materials transfer device be composed of at least three longitudinal sections (I, II, III), the first section (I) having a stationary, inclined stepped grate (11), the middle section (II) having a comparatively short push grate (13) and the third section (III) having a further stationary, inclined stepped grate (15). The device ensures effective distribution of the material to be heat treated across the direction of transport, reliable break-up of incrustations formed for example on the bed of bulk materials, and finally overall enhanced recovery or recuperation of heat from the klinker back into the furnace system and hence further reduction of the specific heat requirement of an entire cement klinker production line.

Title: Cross-wound bobbin removal device
Inventor: BUNGTER HELMUT
IPC: B65H67/06
Filed: 1991-05-03
Abstract: To remove doffed bobbin from a cross winder, therecirculating carrier belt (14) has a fixed laying place (1-6)for each bobbin (19) doffed at a spinning station (12). A system(17,18) at the unloading end (16) of the carrier belt (14)identifies each bobbin (19) according to its laying place (1-6)and records the necessary data. Pref. at each carrier beltunloading position, where there is a bobbin classification unit,the bobbins are transferred to a holding position at a bobbinstorage stretch, to be gathered into a tightly packed row. Thestorage stretch is a belt parallel to and pref. below the carrierbelt. The holding position of the storage belt also forms theremoval end of the belt. As the unloaded bobbins (19) passthrough the classification unit (17,18) they are also identifiedby their laying place (1-6) on the carrier belt. When the carrierbelt (14) has been cleared of bobbins, it is moved forwards orbackwards until the laying spaces (1-6) are exactly perceived inplace at each winding station (12) for the bobbin (19) to betransferred by the doffer (13). After each bobbin has been placedon the storage belt, the storage belt is advanced by a bobbinwidth. The bobbins are automatically classified and given dataidentity on transfer from the carrier belt to the storage belt.

Patent DE-4129153-A1 (DE)
Inventor: KOLDITZ JOACHIM DIPL ING
IPC: G21C17/017
Filed: 1991-09-02
Abstract: A process is disclosed for inspecting heat exchanger tubes in a heat exchanger. Heat is transferred from a first medium to a second medium that is isolated from the first medium in a gas- and liquid-tight manner, and the heat exchanger tubes are fixed into position by spacers. In order to inspect a heat exchanger tube, a measurement probe is inserted therein and the tube is exposed section by section to an electromagnetic alternating field having a predeterminable frequency that generates local eddy currents in the tube wall. The local eddy currents induce in an eddy current sensor a voltage signal that varies depending on the state of the material and the thickness of the tube wall. In order to detect the position and the tight fit of a spacer, the voltage signal induced in a tube section by a spacer is stored and the voltage signals stored during inspection of a heat exchanger are evaluated by comparison with a reference signal.
