Patent DE-3540973-A1 (DE)
Title: Simultaneously separating off SO2 and NOx from flue gases which are highly loaded with NOx and HCl
Inventor: HOELTER HEINZ DIPL ING
IPC: B01D53/60
Filed: 1985-11-19
Abstract: It is known, downstream of combustion boilers of fossil-fuelled power stations, to scrub out SO2 and NOx simultaneously from the flue gases by iron chelate solutions. In the case of flue gases having comparatively high HCl loads, it is known to provide acidic HCl scrubbing upstream of the actual simultaneous scrubber. A disadvantage in this case is that the chloride loads which occur in the acidic stage must be evaporated since they are not passed on to an outfall. However, the evaporation is relatively complex and additionally introduces a landfill problem. In order to avoid these disadvantages, according to the invention it is proposed that the flue gases are scrubbed with iron chelate complex salts, which occur in the scrubbing solution, and the scrubbing solution is passed via an electrolysis cell and a part of the iron chelate complex salt is reduced from iron III to iron II and simultaneously the alkali metal chlorides in the scrubbing solution are decomposed by appropriate control of the current strength, chlorine gas forming at the anode and, in the scrubbing circulation, alkali metal hydroxide (for example NaOH), which serves in the circulation for the absorption of SO2/NOx and HCl from the flue gas.

Title: Combined vertically operating windscreen wiper and windscreen heating system for motor vehicles of all types
Inventor: GRIESEL HEINRICH
IPC: B60S1/34
Filed: 1986-02-18
Abstract: Instead of the known windscreen wipers a windscreen wiper (1), which can be extended lengthwise, is moved up and down in the vertical direction - perpendicularly with respect to the longitudinal axis of the windscreen (3) - and hence wipes the entire surface of the windscreen (3) free of precipitation even if the width of the windscreen (3) increases continuously towards its lower frame part (trapezoid) and even if the windscreen (3) is curved at the sides. By attaching a transparent second window pane (17) from the inside to the windscreen (3) a gap is formed into which there is blown from below, via a distributor tube provided with nozzles and/or slots, heated blower or compressed air which produces by means of outlet openings, which are arranged at the top of the second window pane (17) and can be regulated, a build-up of heated air. This has the effect that the entire surface of the windscreen (3) remains free of ice and clear even at low outside temperatures while the heated air emerging from the gap (18) serves for heating the interior of the vehicle. By combining with the "Combined precipitation deflecting, washing and anti-dazzle system" (German Patent Application P 3501896.8 of 22.01.1985) the blower for the customary air-conditioning system is rendered superfluous. <IMAGE>

Title: Device with two centrifugal masses which are rotatable in relation to each other
Inventor: FRIEDMANN OSWALD
IPC: F16F15/131
Filed: 1986-04-01
Abstract: In the case of a device with a damping device which is provided between at least two centrifugal masses which are rotatable in relation to each other and which contains at least one slip coupling, for better adaptation of the damping capacity of the device to the respective application and consequently for optimising the damping characteristic of the device and extending the possible area of use, the slip coupling is designed in such a way that the moment which can be transferred by it is variable. By such a design of the slip coupling, it is possible to damp the vibration peaks occurring between the centrifugal masses, which are attributable to the degree of non-uniformity of the moment delivered by the internal-combustion engine.
Patent DE-3612957-A1 (DE)
Title: Rotational movement system for receiving and guiding sensors in the production of continuously advancing web material
Inventor: MAYER HELMUT DIPL ING
IPC: G01B5/00
Filed: 1986-04-17
Abstract: The production of web material of all kinds is automated nowadays. The desired values regarding uniform thickness, weight, moisture content, opacity, smoothness and ash are optimised. This results in greater economy and higher quality. Measurement is usually carried out by means of sensors ("transmitter" and "receiver") 1 and 2, Fig. 1, guided above and below the web. Various physical processes are used. Until now the sensors were moved in a translatory, direction-changing manner, in a traversing frame, with acceleration and delay. This system is complicated in construction and susceptible to faults. A more simple guidance is the continuously "rotational" guidance. Articulated arms 3 and 4 permit a closed, synchronous movement of the sensors 1 and 2. 3 and 4 are mounted at 5 and 6 in the variable-size frame which is pivotable about 18. <IMAGE>

Title: Mechanical pulse generator for a jigging machine
Inventor: STRAUSS WERNER
IPC: B03B5/24
Filed: 1986-07-04
Abstract: The parameter setting in a pulse generator for an air-pulsed jigging machine is performed with purely mechanical means. A double-slotted sleeve (2) around a rotor (1) in a casing (5) having two chambers determines the pulse duration and the pulse commencement relative to the rotor position. The times can be altered during operation. The pulse length and pulse shape can be influenced by the slot width and slot shape. Throttle elements (17) in the lines enable the air quantity to be limited, which can be necessary in particular if the pulse generator is used simultaneously for a plurality of pulse chambers. <IMAGE>

Title: Drive arrangement
Inventor: RENGER UDO DIPL ING
IPC: F16D3/10
Filed: 1986-12-06
Abstract: A description is given of a drive arrangement with a first, driving shaft and a second shaft (3) which can be driven via a gear mechanism in a defined angular position relative to the driving shaft, the gear mechanism having a driving gear (1) held in torsionally rigid fashion on the second shaft. In order to achieve as simple as possible an adjusting operation for the setting of the phase angle of the two shafts relative to one another, the driving gear is to be divided into a hub part (5) connected to the second shaft (3) and a rim part (6) which can be driven by the first shaft, these being connected to one another by frictional engagement in such a way that they transmit reliably the driving torque which occurs during operation but can rotate relative to one another, overcoming the frictional engagement, when a twisting torque which far exceeds the driving torque is applied. <IMAGE>
Patent DE-3642204-A1 (DE)
Title: Ink jet printer
Inventor: ABE NOBUMASA
IPC: B41J2/20
Filed: 1986-12-10
Abstract: In an ink jet printer, to produce dots on a recording medium ink droplets are ejected from nozzles of a print head located opposite the recording medium. In order to be able to use conventional wood-free paper, films, such as are used for overhead projectors, or other material as the recording medium without the droplets smearing on the recording medium, the invention provides a drying device which heats the recording medium in such a way that the heat still remains in the recording medium for a certain time even after the ejected ink droplets have impacted on the recording medium. The ink droplets on the recording medium which have swollen in a ball shape due to their surface tension are dried in this state and can subsequently no longer become smeared.

Patent DE-3701568-A1 (DE)
Title: Screw mechanism
Inventor: KORTHAUS BERND
IPC: F16H25/20
Filed: 1987-01-21
Abstract: A screw mechanism with a rotatable threaded spindle mounted in axially non-displaceable fashion has a threaded nut driven in the axial direction on the latter, within a nut housing, the nut being secured against rotation in an axial slot in the nut housing by means of a radially projecting extension. The nut housing supports a torque tube which passes through an outer housing at its end, coaxially accommodates the threaded spindle and has a working end in its outer, free region. On the outer circumferential side of the nut housing, a mechanism part can be moved axially between two axially spaced stops and connected firmly but releasably in a tension-proof manner to the latter. Firmly connected to the mechanism part and arranged ahead of the latter in the direction of extension of the torque tube are outer stops to which are assigned counter stops arranged ahead of them on the outer housing in the direction of extension of the torque tube. Secured on the mechanism part is an outward-projecting support with a working end in its outer, free region. A separate driving motion can be derived from the relative motion between the driving end on the torque tube side and the driving end on the support side.

Title: Bridging device for loading ramp - uses end switch mounted beneath extension of pivoted bridging surface
IPC: B65G69/28
Filed: 1987-08-04
Abstract: The bridging device uses an end switch (19) mounted underneath an extension (8) at one end of a pivoted bridging surface (1), which is extended to bring it into contact with the support edge of a load platform (22), allowing the bridging surface (1) to pivot downwards when the load platform (22) is below the plane of the ramp (3). When the extension (8) is displaced downwards, the switch element (20) of the end switch is moved past a counter-bearing (21), without contact with the latter. The relative movement of the extension when it fails to contact the load platform (22) causes the switch element (20) to be brought into the line of contact with the counter-bearing (21) for subsequent operation of the end switch (19), to return the bridging surface (1) to its zero setting. ADVANTAGE - Automatic zero return for either pivot direction.
