Title: Measuring arrangement for detecting current or voltage values
Inventor: SIBLER WALTER DIPL ING
IPC: G01R19/252
Filed: 1983-06-22
Abstract: In this arrangement, a pulse sequence, the frequency of which is proportional to the current or voltage value to be measured, is generated in accordance with the charge balance method by means of an integration arrangement (I) followed by oscillation-generating means. So that values or changes of the values in the range of small currents or voltages can also be rapidly detected, the evaluating electronics (VCO), the output frequency of which is also proportional to the value to be detected, are driven by the output signal of the integration arrangement (I) via a differentiating chip (DB). The invention can be mainly used for measuring low currents in neutron flux measurement. <IMAGE>

Patent DE-3338217-A1 (DE)
Title: Locking tool for screw connections with polygonal engagement bodies of different size
Inventor: JOCHER REINER
IPC: B25B13/48
Filed: 1983-10-21
Abstract: The invention relates to a locking tool for screw connections with polygonal engagement bodies of different size, which are designed, for example, as a nut or a screw head. The locking tool contains two socket wrenches which lie one inside the other and can be manually rotated separately and of which the inner socket wrench can be moved axially to a limited extent, but by at least its slip-on length, relative to the outer socket wrench and can be clamped into an end position by a compression spring attached between the two. In this position, the outer socket wrench alone can be slipped onto its allocated polygonal engagement body of the screw connection, for example onto a hexagon nut, without the inner socket wrench touching the engagement body allocated to it, for example a screw head. The two engagement bodies can then be restrained against one another by one-hand operation of the locking tool, there being limited radial mobility of the engagement bodies relative to one another, which permits adjustability.

Patent DE-3417332-A1 (DE)
Title: Device for detecting leaks, in particular in pipelines and containers
Inventor: KOBERLING HERBERT DIPL ING
IPC: G01M3/16
Filed: 1984-05-10
Abstract: The invention permits the known detecting methods for monitoring and locating leaks also to be used where they have previously failed. For this purpose, the outer skin of an object to be observed is produced or supplemented as follows:   1.) The outer skin consists of two external, electrically conductive plastics webs with an inserted electrically conductive layer. In the case of a petrol tank, this electrically conductive layer also consists of plastic, but it is an electrically conductive layer which is filled with a conductivity improver for petrol in the case of, e.g., a special landfill composed of a water-saturated sand stratum. By contrast with the state without such a skin having been produced, in the event of a leak the electrical values are now so strongly varied that the known electrical measurement methods respond. 2.) The outer skin consists of an open-cell plastic layer which is leakproof on the outside. Appropriate sensors are introduced into this layer. By contrast with the earlier, free outflow, the medium is now forcibly guided to the sensor, accompanied by a reliable and increased effect. 3.) The outer skin itself forms a narrow container. It thus surrounds a gas tube and is filled with pressurised water. Instead of the noise of outflowing gas, which cannot be detected, it is now possible for the noise of water to be acoustically located as it enters the gas tube. s

Title: Radiant ceiling heating system
Inventor: SCHULTE HERBERT
IPC: F24D5/08
Filed: 1984-08-27
Abstract: In a radiant ceiling heating system according to the invention, one or more structural units (16, 17) with preferably in each case three parallel straight radiant tube sections (11, 13, 15 and 19, 20, 21) are arranged one behind another. The burner (10) suspended below the ceiling works directly into the central radiant tube (11) which has a slightly greater tube diameter than the two outer tubes (13, 15). Provided in each case at the end of a straight tube section (11, 19) is an elbow (12) which diverts the heating gases into a second straight tube section (20, 13) which is flowed through in the opposite direction and at the end of which a further elbow (14) deflects the heating gases into a third parallel tube section (15, 21) with a fan (25) arranged at its end, which conveys the heating gases through the pipe system by means of low pressure. As a result of the element design, such a radiant ceiling heating system can be extended at will by means of structural elements which can be mass produced, with in principle the same pipe arrangement. <IMAGE>

Patent DE-3432328-A1 (DE)
Title: Structure for varying the air boundary layers of a heat-transmission roller
IPC: D06B23/18
Filed: 1984-08-30
Abstract: The invention relates to a simple mechanical system, by means of which the composition of the boundary-layer atmosphere connected to the passage of a web around a heat-transmission roller is removed, reduced or varied. The aim of the invention is to eliminate the air layer between the web and the heat-transmission roller or to remove as much air as possible, so that more intimate contact is achieved between the web and the heat-transmission roller, or to vary the pressure and the composition of the atmosphere to the effect that a higher efficiency of the heat transmission from the roller to the web is achieved. For this, the mechanical structure can have a squeezing-off roller which is located between the heat-transmission roller and by which the air boundary layer adhering to the web is stripped off before the contact of the web with the heat-transmission roller. At the same time, a vacuum can also be applied at the squeezing-off roller. Furthermore, the object of the invention is to reduce the temperature of the air boundary layer by cooling the latter and by using fixed boundary-layer air removal rods and/or squeezing-off or stripping-off rollers. The squeezing-off roller is covered with a soft surface, preferably of rubber or a plastic, so that it comes into intimate contact with the heat-transmission roller and is driven as a result of this contact.
