Title: Process for treating flushing waters, in particular for eliminating environmentally harmful metal ions and apparatus for carrying out the process
Inventor: HOLZER WALTER
IPC: C25D21/22
Filed: 1983-12-21
Abstract: The invention relates to a process and an apparatus for treating flushing water to eliminate environmentally harmful metal ions and/or gaseous emissions. The invention consists in that a by-pass is present in the flushing circulation, for example of an etching unit, from which part-quantities of the circulating flushing agent are passed directly through ion exchanger resins. It is essential that the by-pass line, in which the ion exchanger is located, branches off from the pressure line of a circulation pump, which leads to spray jets fed by the flushing liquid, and opens downstream of the ion exchanger into the flushing medium vessel through the outlet. According to the invention it is provided that the feed of the water softener is arranged underneath the overflow of the intermediate vessel (syphon) in such a manner that the minimal flow through the ion exchanger is ensured as a result of the height difference. <IMAGE>

Patent DE-3405317-A1 (DE)
Title: Sugar-cane harvesting machine
Inventor: LEIGERS GUENTER
IPC: A01F29/06
Filed: 1984-02-15
Abstract: The present invention describes a chopper for a sugar-cane harvesting machine, in which the cutters of the upper chopper shaft are inclined in the direction of rotation and the cutters of the lower chopper shaft extend radially. During operation, the particularly lower cutter participating in the cut leads the particular upper cutter participating in the cut by a small amount. As a result of this measure, the chopped pieces are thrown onto a conveyor band in a wider arc than in choppers of known design, so that the risk that individual stalk fragments will fall between the almost horizontally set cutter disc and the conveyor band onto the ground is virtually prevented.

Abstract: In this apparatus, the control head (2) is linked with a swivel joint (4) to the front end of the driving pipe, which swivel joint is arranged in the outside-diameter area lying at the top or bottom in operation. Starting from there in both peripheral directions, a regulating unit (13) is in each case arranged at an arc angle of about 120 DEG . The two regulating units can be driven independently of one another in a reciprocating manner. The control head can be pivoted in various ways, while the adjusting device takes up little space. <IMAGE>

Abstract: The invention relates to an evaluating method for the pixel signals of an image transducer, in which digital signals corresponding to the colour and brightness values are provided for each discrete pixel. To achieve a real-time processing of the video image with respect to a change in signal amplitudes of adjacent pixels (Xm, Yn; Xm-1, Yn; Xm, Yn-1), a horizontal pixel comparison is carried out in the first half of a read-out clock period (period AT) and a vertical pixel comparison is carried out in the second half. To carry out the method, a random-access memory (RAM) controlled by a clock status control, a buffer register (ZR) and a subtracting chip (SU) are provided. The invention can be used mainly in automated surface checkers. <IMAGE>

IPC: H01H19/58
Filed: 1984-05-15
Abstract: A pulse transmitter having an electromechanical contact device, of which some are contact tracks 3, 4, 5 and the others are associated contact springs 6, 7, 8, has two pulse outputs. In order in this case to ensure that only one of the outputs at a time carries a signal, as a function of the adjustment direction of the contact device, only one of three contact tracks 3, 4, 5 is provided with interruptions 20 in the active region of the associated contact spring 6. The two other contact springs 7, 8 in contrast each have a switching device allocated to them, which switching device releases the current path to only one of the pulse outputs as a function of the adjustment direction. <IMAGE>

Title: Hydraulic working cylinder with integrated stroke-displacement measuring system, in particular for underground support and extracting systems and the like
Inventor: HESSEL HEINZ
IPC: E21D23/16
Filed: 1984-08-16
Abstract: The invention is directed towards a hydraulic working cylinder which is equipped with a built-in stroke-displacement measuring system. The latter consists of a sensor bar which is supported on the base of the working cylinder and engages in an axial bore of the piston rod. Arranged at the head of the sensor bar is a measuring head which is formed by a rotary potentiometer and a small rotor which sits on the drive shaft of the rotary potentiometer and, with a sliding block or the like, engages in a helical groove on the inner wall of the axial bore of the piston rod. In this way, the stroke movement of the piston of the working cylinder is converted into a rotary movement of the rotor and thus into a rotary movement of the rotary potentiometer.

Title: Process and apparatus for treating etching bath solutions containing HCl and ferrous chloride
Inventor: ANUSCHEWSKI HERBERT DR
IPC: C23F1/46
Filed: 1984-11-15
Abstract: A process for treating etching bath solutions containing hydrochloric acid and ferrous chloride is to be developed in such a way that it can be implemented economically without great expense on apparatus. For this purpose, it is provided that the solution is introduced into a vacuum chamber at elevated temperature and moved through this chamber by means of a conveyor screw, dried ferrous chloride being discharged by the screw. Preferably, this is then thermally decomposed at high temperature into iron and chlorine, and the chlorine released can be used for converting not yet decomposed ferrous chloride into ferric chloride. For carrying out the process, an apparatus is provided in which, in a vacuum chamber (3), a conveyor screw (1) is arranged which has, on its discharge end, preferably a second conveyor device, in the region of which a device for generating a high temperature is located. <IMAGE>

Title: Arrangement for the automatic irreversible disabling of a malfunctioning distance counter
Inventor: HAUTVAST HEINZ-JOSEF
IPC: G06M1/04
Filed: 1985-01-23
Abstract: For a printing-type distance counter (1) of the type of a wheel revolution counter, an arrangement is proposed by means of which it can not only be verified that an intervention has taken place but which prevents the distance counter (1) from being made operable again after the intervention. This is achieved by the fact that preferably the last gear stage in the drive connection of the distance counter (1) is constructed as a helical gear, that the driving shaft (50) of the helical gear is supported axially displaceably against the action of a compression spring (54) in such a manner that another gear element (47) arranged on it disengages from a further gear element (45) allocated to the gear element (47), during the axial displacement of the shaft (50) in the event of a blockage of the distance counter (1), and thus the drive of the distance counter (1) is interrupted. <IMAGE>

Patent DE-3524243-A1 (DE)
Title: Plant vessel in combination with an overvessel
Inventor: LESSEL HEINZ
IPC: A01G27/06
Filed: 1985-07-06
Abstract: The invention relates to a plant vessel 1 in combination with an overvessel 2, the water absorption of the flower earth taking place in known manner by pouring over the free surface of the plant vessel. Disadvantages are the formation of run-through channels through the flower earth, thermal shock as a result of a lack of identity of the temperatures of the watering water and of the flower earth, a lack of balance between water quantity and requirement, as well as silting up and hardening of the flower earth in particular in the central space.   These disadvantages are avoided by arrangement of a porous, salt-free and lime-free plant vessel 1 in a pore-sealed overvessel 2 made of ceramic or other material basis, merely the standing surfaces 3 and 4 directed towards one another of the two vessels corresponding and the overvessel 2 moreover being designed in such a manner that a circumferential gap 5 with a generally prismatic gap cross-section 6 is formed. The dimensioning of this gap is dependent upon the water requirement of the plant and the thickness of the wall of the plant vessel 1. The water diffuses in a very finely dispersed manner into the inner space 1.2 of the plant vessel 1, in which case essentially the mechanism of the quantising off of a transversely ventilated capillary could be useful. <IMAGE>
