Title: Method for removing oxygen dissolved in water
Inventor: HEINZELMANN ULRICH DIPL CHEM
IPC: C02F1/20
Filed: 1988-02-15
Abstract: It is the object of the invention to indicate a method which essentially surpasses the known physical, chemical and electrochemical methods for oxygen removal. This object is achieved if the dissolved oxygen is reduced at the cathode surface of an electrolysis system (1, 1'...8, 8') fed with external power, simultaneously cations with polyvalent metals are generated at the anode (3, 3') of the electrolysis system in an oxidation state which is beneath the highest oxidation state and the undissolved reaction products formed are separated off through apparatuses (8, 8'). The advantages in comparison with the physical methods are a considerably less complex apparatus and an energy-saving with respect to the chemical arrangements, in the avoidance of a continuous addition of chemicals and the advantage with respect to the electrochemical processes is a very decisively improved removal of oxygen. The invention is principally used in systems having oxygen entry, for example in heating units. <IMAGE>

Filed: 1988-02-29
Abstract: The invention relates to a process and apparatus for processing elastomeric material in particular plastic, rubber and a mixture thereof in roller-head-apparatus in which the material to be processed is plasticized and homogenized in an extruder, extruded from an extrusion head provided on the extruder and then is led through an aperture formed between two rollers. It is the object of the present invention, with an especially simple extrusion head in a roller-head-apparatus to produce uniform and dimensionally exact sheets or foils of different thicknesses without changing structural parts. The invention achieves this in that material formed in plate form by parallel outlet surfaces of the extruder head is led through an aperture space formed between a concave cylindrical surface of a stationary forming tool and the circumferential surface of one of the rollers of the calender before the material enters the space between the two calender rollers.
Patent DE-3808338-A1 (DE)
Title: Stacking column
Inventor: WALKER ERWIN
IPC: B65G1/14
Filed: 1988-03-12
Abstract: A stacking column for stacking store articles has pawl levers which are rotatably mounted one above the other and can be swivelled from a resting position, via a ready position, into a working position and back again. When a store article is laid down, a pawl lever in the ready position passes into its working position and, at the same time, a pawl lever arranged above passes from its resting position into its ready position. For the purpose of locking the pawl levers located in the working position, a blocking bar is arranged, so as to be displaceable between an unlocking position and a locking position, on the stacking column. The blocking bar has locking elements which, in the locking position, engage on in each case one of the pawl levers and block the latter individually in the working position.

Title: Swivel joint for seats with an adjustable backrest, in particular motor-vehicle seats
Inventor: KLUETING BERND ING GRAD
IPC: B60N2/225
Filed: 1988-03-29
Abstract: The swivel joint, which comprises a fixed joint part assigned to the seat part and a pivotable joint part assigned to the backrest, has a swivelling spindle which connects the joint parts to each other and by means of an eccentric portion keeps the tooth profiles of a spur gear, which is mounted on the eccentric portion and is connected to one joint part, in engagement with tooth profiles of an internal gear of the other joint part, which internal gear is mounted on the central portions of the swivelling spindle. The tooth profiles of the teeth of the known swivel joints have the same profile angles on both sides which results in the self-locking of the system being equal in both directions of movement. This has the effect that the adjusting movement in the direction of movement supported by the backrest weight is more smooth-running than for the opposing pivoting movement of the backrest. The intention is to provide a swivel joint, the adjusting and locking device of which has a greater self-locking when the backrest is pivoted backwards than when the backrest is pivoted forwards. The swivel joint has, for this purpose, gears having teeth which on their one unidirectional sides of the tooth profiles have a larger profile angle than on their other unidirectional sides of the tooth profiles. By virtue of this measure, when an adjustment takes place in which the tooth profiles having a smaller profile angle slide one on top of another, a greater self-locking of the adjusting and locking device of the swivel joint is obtained than in...

Patent DE-3836190-A1 (DE)
Inventor: BISSINGER FRIDOLIN
IPC: B22D19/00
Filed: 1988-10-24
Abstract: A full-mould casting process for manufacturing castings with internal high-temperature thermal insulation (2) permits rational, defect-free mass production of castings with low wall thicknesses and narrow tolerances. As the heat insulation (2) is impermeable to gas, however, the steam in the foam mould (11) cannot pass across the wall of the pattern. Because of the insulating effect of the high-temperature thermal insulation (2), the steam can be directed over the perimeter of the pattern and removed by suction on the opposite side while retaining sufficient heat in the region of the steam outlet for complete foaming.
Patent DE-3839049-A1 (DE)
Title: Method and apparatus for thermal denaturation
Inventor: SCHUBERT WERNER DR MED
IPC: C12M1/12
Filed: 1988-11-18
Abstract: Chemical fixation methods such as formalin fixation are increasingly being replaced by physical methods for the denaturation of organic objects such as for excised samples. It is required for the stabilisation that no chemical substance is added to the body cell/a tissue, bacteria, for example, during the denaturation. However, it is also necessary, especially for sensitive histochemical tests, that as little as possible, or no, substance is lost from denatured organic material. A method for this is presented and examples of apparatuses are given. The stabilisation must take place under an elevated pressure of water vapour in a pressure container which can be designed in the shape of a bottle and utilising the property of microwaves to penetrate plastic or glass. Under these particular physical conditions it is possible for the water, which comprises about 80% of the total substance of body cells (cell water, which is also present in the cell nuclei), to be dielectrically heated by microwaves in the pressure vessel, which provides several advantages for histochemistry and simultaneously for morphological histological investigations with the aim of more accurate information and correct diagnosis.
