Patent DE-3829512-A1 (DE)
Inventor: BERGER HERMANN
IPC: G01F1/20
Filed: 1988-08-31
Abstract: The upwardly extending outlet of a pump contains a non-floating permanent magnet which tends to assume a lower end position but is propelled upwardly in response to admission of a metered quantity of liquid into the outlet to initiate the emission of a signal by a sensor. The emission of such signal persists as long as the actuator remains above its lower end position. The sensor is connected with the resetting input of a counter by way of an OR circuit. The n-th output of the counter transmits a signal to an alarm signal generating circuit in response to transmission of a certain number of consective timing pulses to its counting input prior to transmission of a signal to the resetting input. The timing pulses are transmitted by a generator which also transmits pulses to the pump to thus determine the frequency of admission of liquid into the outlet. A rectangular wave oscillator receives signals from the sensor and transmits a series of signals to the OR circuit with a delay which equals or approximates the length of the interval between two consecutive timing pulses. The oscillator starts to transmit signals to the OR circuit only if the signal which is emitted by the sensor persists during the aforementioned delay. This ensures that no alarm signal is generated if the viscosity of pumped liquid is so high that the actuator is incapable of returning to its lower end position during the interval between successive admissions of liquid into the outlet.

Title: Process for the regeneration of arsenic-contaminated sorbents
Inventor: KAIZIK ALFRED DR
IPC: B01J38/60
Filed: 1988-05-14
Abstract: In the selective catalytic removal of nitrogen oxides from flue gases of slag-tap-fired furnaces, in particular those having ash recycling, the problem occurred that the catalysts based on titanium oxide were rapidly deactivated by arsenic compounds. The catalysts thus damaged previously had to be replaced by new ones. On the other hand, there is the possibility of removing in advance the arsenic compounds from the flue gas by a titanium oxide-based sorbent provided upstream of the catalyst. It is thus desirable to find a process for the regeneration of arsenic-laden sorbents. Arsenic-laden sorbents can be regenerated by washing with an inorganic or organic acid. Regeneration of arsenic-laden sorbents.

Title: Stack-monitoring device
Inventor: WAGNER BURKHARD
IPC: B65H7/04
Filed: 1988-10-21
Abstract: The invention relates to a stack-monitoring device for use on sheet feeders working intermittently. The object of the invention is to provide a stack-monitoring device which guarantees that sheets are sucked off only when the stack top edge or the front edge of the sheet stream is located in a specific tolerance range optimum for separation. For this purpose, there is arranged at the end of the specific tolerance range of the sensing member (2) for the stack-transport control a transmitter (4) which is connected via a switching amplifier (5) to the "sheet-feed interruption" input of the air control (6) for the suction drum (3) of the sheet feeder. If the flat-stack top edge or the front edge of the sheet stream comes out of this region, the sheet feed is interrupted, without machine standstill times occurring. <IMAGE>

Title: Synchronous control for advancing and slide-bar cylinders in self-advancing support units
Inventor: DETTMERS MICHAEL
IPC: E21D23/26
Filed: 1989-01-25
Abstract: The invention relates to an apparatus for controlling the slide-bar cylinders of hydraulic self-advancing support units as a function of the allocated advancing cylinders with the use of a control-valve device for pressurising the said cylinders and with an activating valve (17) (preferably hydraulically operable) which is arranged in a connecting line (18) connecting the annular spaces (10, 14) of the two cylinders. Furthermore, the control apparatus has an overflow valve which is allocated to the connecting line and which discharges the pressure fluid expelled from the annular space (14) of the advancing cylinder (1) during the advancing operation when the slide-bar cylinder (2) is fully retracted. According to the invention, the valve device (21) forming the overflow valve is located in the piston (20) of the slide-bar cylinder (2), it being arranged in such a way that it opens by stem actuation the connection between the annular space (10) and the piston space (9) when the slide-bar cylinder is fully retracted. In this arrangement, the valve device (21) preferably has a closing valve which opens and closes in the opposite direction to the overflow valve and shuts off the outflow passage arranged in the piston (20) of the slide-bar cylinder when pressure fluid is admitted to the piston space (9) of the slide-bar cylinder. <IMAGE>

Title: Tachogenerator having a rotor position transmitter for a three-phase servomotor with rotation-speed regulation and electronic commutation
Inventor: KOERNER HERBERT DIPL ING
IPC: H02K29/14
Filed: 1989-04-01
Abstract: The invention relates to a tachogenerator with a rotor position transmitter for a three-phase servomotor having rotation-speed regulation and electronic commutation. The tachogenerator is formed by an annular stator core (2) and a permanent magnet (7) which is mounted therein on a rotating body (6). The rotor position transmitter consists of three Hall sensors (3), which are fitted at offset angles, and an impeller wheel (8) which is connected to the rotating body (6). According to the invention, a mounting body (1), which is fitted with the other components, has an annular flange (9) with elongated holes (12) so that the mounting body can be mounted at an optimised angular position with respect to a bearing plate of the three-phase servomotor. Furthermore, the stator core (2) can also be adjusted in the rotation direction via a detachable mounting into an optimum angular position with respect to the mounting body (1). In a further refinement of the invention, the impeller wheel (8) can also be mounted on the rotating body (6), in an optimum position with respect to said rotating body (6), via elongated hole connections. This results in it being possible to match all the parts of the tachogenerator and of the rotor position transmitter to one another irrespective of the geometry of the three-phase servomotor, for optimisation. <IMAGE>

Title: Dissolving high purity zinc in electrolyte - has atomised zinc in lower part of vessel meeting electrolyte fed from above through porous layer and then falling to vessel bottom
Inventor: SCHNETTLER ROLAND
IPC: C25D21/14
Filed: 1989-12-01
Abstract: Process for displaying high purity zinc in an electrolyte involves atomising liquid zinc in a chamber and  bringing it into contact with the electrolyte. The atomised zinc is burnt under a supply of oxygen. The processing unit comprises a tower-like chamber into which the electrolyte is fed from above through a feed pipe. Liquid zinc from a zinc melting station is fed into the lower region of the chamber through a nozzle assembly. A bath of electrolyte with the dissolved high purity zinc is maintained at the bottom of the chamber. The electrolyte is drawn off through an  outlet. The electrolyte fed from above flows through a fibrous layer and trickles onto the atomised zinc. The chamber is ventilated by an upper outlet whereby air and exhaust gas are pref. fed through a filter layer above the electrolyte feed pipe. An ignition device is positioned near the nozzle assembly. ADVANTAGE - A sufficiently high dissolving speed is attained with the introduction of an electrolyte of relatively high pH value.

Title: Braking pressure control motor vehicle - has regulating valve with regulating piston and valve closure assembly
Inventor: SCHONLAU JUERGEN
IPC: B60T11/34
Filed: 1990-02-03
Abstract: The braking pressure control for automotive vehicle comprises a regulating piston (5) and a valve closure (6) and which governs the connection between a pressure-fluid inlet (3) and a pressure-fluid outlet (4). The valve closure is coupled to a pressure-responsively displaceable control piston (20) which is normally free to move upwards under inlet pressure to keep the valve open but on vehicle deceleration exceeding a threshold an inertial weight (33) prevents displacement of the control piston (20) which in turn limits upward movement of the closure so that the valve is able to close and open in a cyclic manner and effect pressure modulation.
