Title: Ceiling rotating support for holding medical apparatus, whose position can be fixed, and the connections of power-supply and gas-supply lines in the clinical field
Inventor: HAHMANN GUENTHER ING GRAD
IPC: F16M11/06
Filed: 1981-01-14
Abstract: The invention relates to a ceiling rotating support for holding medical apparatus whose position can be fixed by brakes and stops. It contains the connections for the power-supply and gas-supply lines. The ceiling rotating supports have to absorb large vertical and horizontal moments because of the weights of the medical apparatuses. Despite this, they are intended to be capable of being braked safely and rotated easily. For this purpose, between a rotatable bearing journal and a fixed bearing flange, they have a wire support which is prestressed up to a basic torque over a bearing ring by means of screw bolts and, in the bearing flange, have a hose brake which is supplied with compressed air via a connection and brakes the bearing journal. Stops on the bearing journal form rotation paths which are defined as far as stop journals which are arranged in the bearing flange such that they are also adjustable. The advantages of the ceiling rotating support are evident in the simple construction and reliable braking. The wire support and the hose brake are controlled components; the same applies to fitting.

Title: Method for producing a pressure differential in a fluid and system for implementing the method
Inventor: GROENECKE OTTO
IPC: F03G7/00
Filed: 1981-06-03
Abstract: The invention relates to a method for producing a pressure differential in a fluid, which acts on machines or engines, and a system for implementing the method. According to the method, two fluids of different concentration are each fed past one side of a semi-permeable dividing wall respectively, the fluid with the higher concentration being under a given hydrostatic pressure. By osmotic processes due to absorption of solvent from the fluid with the lower concentration, the fluid with the higher concentration is diluted with an increase in mass and the pressure then reduced to a predetermined level by expansion of the fluid with the initially higher concentration in a machine or engine. A system serving to implement this method comprises at least one reaction vessel (13), which is divided into two sectional chambers (5, 6) by means of a semi-permeable dividing wall (4). The fluid with the higher concentration flows through the one sectional chamber and the fluid with the lower concentration through the other sectional chamber. That sectional chamber (6) through which the fluid with the lower concentration flows is connected at its outlet (7) to power generating devices (8). In addition a duct (9) is provided for the fluid leaving the power generating device (8) and a discharge line (17) is provided for the fluid leaving the sectional chamber (5). <IMAGE>

Title: Optical waveguide
Inventor: BAEGER HOLM DIPL PHYS DR
IPC: F21V8/00
Filed: 1981-06-12
Abstract: The invention relates to an optical waveguide (1, 1') consisting of a transparent material into which light beams (6) can be introduced from a light source (3). A limiting surface (7) of the waveguide (1, 1') is caused to light up during this process, the light beams (6) which are introduced from the light source (3) being capable of being deflected at a reflection surface (2, 2') of the optical waveguide (1, 1') towards the limiting surface (7). The reflection surface (2, 2') has at least in the area which is more remote from the light source (3) a curvature starting from the light source (3) and proceeding according to an approximately quadratically increasing function. So that with an optical waveguide of this kind light beams (6) of identical intensity and identical direction are emitted at all the points of its limiting surface (7), the reflection surface (2, 2') is formed by a plurality of deflection faces (4) which extend in each case equidistantly from the light source (3) and are inclined at approximately the same angle (5) with respect to the light beams (6).   <IMAGE>

Title: Method and measuring device for measuring the degree of conversion to caramel of a flowable compound
IPC: G01N21/85
Filed: 1981-07-25
Abstract: The degree of conversion to caramel of a liquid during a caramel production process is monitored in that the radiation absorption is measured in a cell (10) through which some of the conversion liquid flows. The light of a light source (1) is supplied via an optical fibre (2) to an optical waveguide rod (6) which, together with another optical waveguide rod (11), forms a measuring gap through which the liquid flows. The end of the optical waveguide rod (11) is connected to a phototransistor (12) which responds to radiation in the near infrared range. The conversion liquid is more transparent to this radiation than to visible light. A reference cell (5) contains a reference liquid. The measurement quantity is determined by forming the difference between the output signals of the phototransistors (12 and 7) of the two cells (10 and 5). <IMAGE>
