Title: Device for the morphological detection/revelation of a primary increase in the gas content in organs/tissues
Inventor: SCHUBERT WERNER DR MED
IPC: G01N1/31
Filed: 1984-12-03
Abstract: According to physical laws, even gas bubbles located in tissue are enlarged by reducing the pressure and, additionally, by exposure to heat. Under a reduced pressure of 400 mbar and, at the same time, by heating to an upper limit of 82 DEG C in a reduced- pressure vessel which contains water, the enlargement in the volume of the gas bubbles is 3-fold, without taking account of the surrounding pressures due to the tissue which is forced apart. This ought to be utilised for assessing a primary increase in the gas content of an organ/tissue, in particular in decompression sickness, and thus also divers' paralysis or caisson disease, in the condition after autochthonous gas release, as well as to explain deaths, which are not uncommonly unclear, for other reasons, in which a latent gas or air embolism may be present. An apparatus suitable for this and for rapid and, nevertheless, non-damaging reduced-pressure fixation of organs and tissues is reported, with the possibility which now exists of establishing in hours an increased gas content in an organ or, which is likewise not unimportant, of ruling it out.
Patent DE-3446525-A1 (DE)
Title: Apparatus for coating, with a controllable coating thickness, lengths of material running over a support roller
Inventor: SOMMER HERBERT
IPC: B05C11/04
Filed: 1984-12-20
Abstract: The invention relates to an apparatus for coating a length of material (2) running over a support roller (1), by means of a slot nozzle. This slot nozzle has an adjustable pre-metering channel (6') as the input and has a likewise adjustable return channel (15). A metering chamber (7) which is in contact with the length of material (2) is situated between the two channels and is bounded in the direction in which the length runs by a metering lip (8) in the form of a doctor blade (11). The slot nozzle functions in such a fashion that the main stream of the coating medium, after passage through the pre-metering channel (6') and entry into the metering chamber (7), is deflected by means of the Coanda effect in the direction of the overflow channel (15). The coating medium is thereby conveyed through the return channel (15) in counter-flow with respect to the direction of motion of the length, so that a coating first takes place which closes the capillaries and pores of the length of material (2) and simultaneously the entry of air adhering to the length of material (2) is also avoided. A coating of the length of material (2) with little pressure then takes place in the metering chamber (7). A strike-through of the coating medium through the length of material (2) is avoided by this mode of coating, especially in thin papers. <IMAGE>

Title: Seal
Inventor: COURA HERBERT
IPC: F16J15/32
Filed: 1985-01-22
Abstract: The invention relates to a seal, in particular for fittings, which have to meet sanitary requirements, the seal being arranged within a housing cover and sealing off an axially movable rod which passes through the latter. The shaping of a seal of this kind ensures that the sealing surfaces exposed to the medium to be sealed off are easy to clean and that, when subjected to pressure by the medium within the annular gap between the rod and the housing cover, the seal is pressed uniformly against the components surrounding it. The seal 1 has, inter alia, an end face (1a, 1b) which falls away approximately symmetrically like a roof towards the rod (5) on one side and the housing cover (2) on the other side from a continuous circular apex line S, in the direction of the negative pressure gradient of the medium at the sealing location (Fig. 2). <IMAGE>

Title: Apparatus for separating potatoes and stones
Inventor: KOOP WINFRIED
IPC: B07B13/00
Filed: 1985-02-14
Abstract: The apparatus for separating potatoes and stones in potato harvesting works on the principle of dynamic dropping behaviour. The harvested mixture runs, on the rubber-finger band of known design, through one or more of the described activator stages, on which the mixture constituents are exposed in a controlled manner to specific dynamic influences. These increase the fractions of dropped stones selectively to 80 to 90%. In contrast to this, in conventional apparatuses without activators, at most 10% of the stones of the mixture material drop according to a mode which can be designated as spontaneous or static. So that as large a fraction as possible of the length of the rubber-finger band can be utilised as an activator stage, the mixture constituents are not deflected obliquely to the side from the band against the flow, as in conventional apparatuses, but in a space-saving way together with the flow by means of an appropriately arranged rotating brush roller. Potatoes resting on the rubber-finger tips are picked up by the rotating bristles to a greater extent than the stones which have dropped between the rubber fingers. Stones, thus accelerated away from the rubber-finger band, land in the vicinity of the end of the rubber-finger band, whereas the potatoes land at a greater distance from this. The two landing regions are delimited from one another by a separating edge. The types of articles are to be fed from their respective landing places to further processing cycles via conveyor bands or the like. A plurality of ... Original abstract incomplete.
