Title: Implantable collection device
Inventor: PARTH REINHOLD
IPC: A61M1/00
Filed: 1987-06-26
Abstract: In the known collection devices body fluid is continuously collected in the collection vessel. After filling of the latter, the body fluid is allowed to flow back by opening a return tube, the vessel being permanently filled. The collection vessel remains permanently on the experimental animal. Tubing lines may become damaged. Fluid remains in the collection vessel and is subject to time- and temperature-dependent changes. Test results can be influenced. The implantable means for discharge of the fluid comprises a three-way valve (Figures 1 and 2) with an actuation element having two positions in one of which fluid is passed from the supply tube (7) via the collection tube (8) into the collection vessel (12). In the other position fluid from the supply tube (7) is passed into the return tube (9). The valve comprises a valve piston (10) axially actuable in the valve cylinder (6). The valve cylinder (6) is fastened on the flange part (11). The advantage of the device according to the invention is that there is minimum impediment of the experimental animal. The fluid collected remains in the collection vessel only during the filling phase, and measurable changes are prevented. <IMAGE>
Patent DE-3721414-A1 (DE)
Title: Detector for heat sources having acoustic evaluation
Inventor: BUIL JUERGEN HEINRICH
IPC: G01S3/785
Filed: 1987-06-29
Abstract: Fires, people or other heat sources in smoky rooms (spaces) could until now be detected and localised only by means of relatively expensive, cumbersome infrared cameras. The acoustically evaluating detector is cost-effective to manufacture, is easy, convenient and simple to use and requires no cooling. An infrared-sensitive pyroelectric sensor records the heat radiation emitted by people or fires in the 6.5-15  mu m wavelength band. After suitable amplification, conversion into sounds is carried out, which are made audible, for example, by means of a headset and whose frequencies change depending on the heat intensity. The sensitivity can be adjusted depending on the ambient temperature (the environmental temperature), so that it is always possible to detect the point in the room where the temperature is highest. The detector makes it possible for a fireman who is moving with heavy breathing protection into a smoky object to localise the source of the fire or to find people. It is likewise possible to localise fires behind claddings or in cable ducts (conduits) and to locate heat leakage on buildings in this way.

Title: Method and device for determining the ovulation period of humans or animals by means of electric detection of the deviation in body temperature
Inventor: UEBE RAINER DIPL ING
IPC: A61B10/00
Filed: 1988-01-28
Abstract: In a method for determining the ovulation period of humans or animals, the body temperature is measured in measurement periods, which preferably succeed one another daily during a menstrual cycle, by means of a temperature sensor and is converted into an electric signal which controls an electric display device. In order to detect the variation in body temperature reliably by means of a low-cost temperature sensor, a mean value of the body temperature, which is measured during successive measurement periods and converted into electric signals, is firstly formed using an electronic averager, and stored. Subsequently, this mean value is compared with newly detected data on body temperature in an electronic comparator device. The data, formed by the comparison, of individual temperature deviations are displayed using the display device. <IMAGE>

Title: Improved method for the energy-saving heating of buildings
Inventor: WOLKE ERHARD
IPC: F24D11/02
Filed: 1988-02-02
Abstract: The method according to main patent ... (Patent Application P 3801199.9) uses the thermal energy obtainable on or in the building for heating the building, in which method a heat pump is employed. A disadvantage of this method is that the solar energy occurring in the immediate vicinity of the building is not used. The improved method is characterised in that a heat-conveying fluid is passed through conduits in or under road and/or path surfaces, is heated there by absorbed solar energy and then supplied to the heat pump. The solar energy occurring in the vicinity of the building is thereby also made usable for heating the building. The improved method according to the invention is suitable in particular for heating detached buildings, such as one- or two-family houses.
Patent DE-3805367-A1 (DE)
Inventor: KARDINAL HANS-JOACHIM DIPL ING
IPC: B41J35/18
Filed: 1988-02-17
Abstract: Image recording processes are known in which a sheet of recording material to be printed in colour is delivered from a sheet magazine to a printing roller, printed there with an initial partial impression and subsequently, for the printing of further partial impressions, re-fed each time to the printing roller through a sheet circulation channel; in this system, the partial impressions are printed in the colour sequence yellow, magenta, cyan and, if necessary, black. To improve the colour reproduction, in the process according to the invention the sheet of recording material (5) delivered from the sheet magazine (4) is first printed with the colour black and, subsequently, after emerging each time from the sheet circulation channel (23) printed with the additional colours yellow, magenta and cyan. The result of this is that on printing the coloured partial impressions, because of the same sheet feed from the sheet circulation channel (23) each time, each of the position tolerances of the sheet of recording material (5) with respect to the recording head (7) is kept as small as possible. <IMAGE>

Title: Process for controlling the process of crystallisation from sucrose solutions
Inventor: PETZOLD DIETRICH DIPL ING
IPC: C07H3/04
Filed: 1988-02-23
Abstract: The process of crystallisation from sucrose solutions is controlled with the aid of certain values measured in the sucrose solution or crystal suspension, e.g. viscosity or consistency, density, conductivity, permittivity, boiling point elevation and the like. A technologically optimal process control is to be ensured by an expedient linkage of simultaneously measured physical variables while changing the process conditions. An uncontrolled supersaturation of the sugar solution or an unwanted slowing down of crystal growth is achieved by using as control variable for the addition of undersaturated sucrose solution to the evaporating crystalliser after the seeding the conductivity or permittivity measured at a viscosity of 150-250 mPa.s or at a density of 1370-1420 kg/m<3>, and subsequently the viscosity or density, until a viscosity of 200-500 mPa.s or a density of 1390-1480 kg/m<3> is reached. The process can be applied to the production of crystalline sugar from sucrose solutions.

Patent DE-3839916-A1 (DE)
Title: Wavelength-selective optical coupler
IPC: G02B6/125
Filed: 1988-11-26
Abstract: An optical coupler is to be specified which is designed using planar optical waveguide technology, has a high wavelength selectivity, and at the same time has a structural length which is as short as possible. Two planar waveguides (WL1, WL2), coupled to one another, are designed with respect to their cross-sectional dimensions and to their refractive indices in such a manner that the fundamental modes of the two optical waveguides (WL1, WL2) in the case of a predetermined wavelength have the same phase coefficients and in the case of all the other wavelengths have different phase coefficients. The two optical waveguides (WL1, WL2) unite in a partial region of the coupler to form a common optical waveguide (WL), and this common optical waveguide (WL) has such cross-sectional dimensions and such a length that two modes (eigenwaves, natural waves), propagating therein, of the coupler, into which waves a fundamental wave is split up which has been fed into one of the two waveguides in front of the common waveguide (WL), are subjected in the case of the predetermined wavelength to such a mutual shift in their phase coefficients that the modes are subjected after the common waveguide (WL) in one of the two waveguides (WL1, WL2) to a superposition in phase opposition and in the other waveguide to an equiphase superposition. An optical coupler of this kind is well suited, due to its short structural length, for monolithic integration (Fig. 1). <IMAGE>
