Title: Plug-in coupling for hose connections
Inventor: WOLF FRANZ JOSEF
IPC: F16L37/098
Filed: 1987-08-25
Abstract: The subject matter of the invention is a plug-in coupling for hose connections, having a coupling 1 and plug connector 2 which is joined to the hose 3 which is to be connected. The sleeve 4 for receiving the hose 3 merges into a tubular part 10 which is integrally formed on the rear side of a baseplate 8. Extending from the latter is a plug-connector pin 5 which projects into a coupling bush 6. The coupling bush 6 is encircled by a spring-sleeve portion 14 which is in latching engagement with a protrusion 15 on the coupling bush 6. The sealing between the coupling bush 6 and the plug-connector pin 5 is achieved with the aid of a ring 16 which consists of an elastomeric material and ensures sealing between the coupling bush 6 and the plug connector 7. The plug-in coupling according to the invention thus permits the fluid-tight connection between the hose 3 and a coupling bush 6 which is, for example, fitted on a unit. <IMAGE>

Title: Process and apparatus for the production of a pressed-bobbin assembly
Inventor: TUEBER JOSEF
IPC: D06B23/04
Filed: 1987-10-02
Abstract: Process for the production of a pressed-bobbin assembly consisting of a predetermined number of yarn bobbins placed coaxially one on top of the other, in the course of the treatment of the pressed-bobbin assemblies on spindles of a spindle carrier of a yarn-treatment appliance, especially of a dyeing appliance. The yarn bobbins of a pressed-bobbin assembly are pushed onto the upwardly extended piston rod of a cylinder/piston arrangement which is set up vertically, a support plate being arranged under the yarn bobbins and on the yarn bobbins. The support plate arranged on the yarn bobbins is connected to the piston rod. The compression of the yarn bobbins is brought about as a result of the retraction of the piston rod. The compression of the yarn bobbins is thereafter fixed by connecting the support plates by means of fixing elements. The pressed-bobbin assembly thus formed is detached from the piston rod together with the support plates and is pushed onto a spindle of the spindle carrier. <IMAGE>

Patent DE-3741775-A1 (DE)
Title: Control circuit for hot air appliances
Inventor: NUTZ KARL-DIETHER DIPL ING
IPC: A45D20/30
Filed: 1987-12-10
Abstract: A control circuit for hot air appliances has a control circuit for controlling the heat output and a control circuit for controlling the speed of a motor for controlling the air flow. The control circuit for controlling the heat output has a momentary-contact switch for increasing the heat output and a momentary-contact switch for reducing the heat output. An evaluation logic evaluates the changes in potential which are caused by actuating the momentary-contact switches and drives a counter which counts upward if the heat output is to be increased, and counts downward if the heat output is to be reduced. A digital-to-analog converter converts the reading of the counter into a current which depends on the counter reading. The current supplied from the digital-to-analog converter flows through a temperature-dependent resistor which generates a voltage dependent on the temperature of the hot air. A comparator compares the voltage dependent on the temperature of the hot air with a ramp reference voltage. Electric power is fed to the heater of the hot air appliance as a function of the output signal of the comparator by a full-wave logic which ensures that electric power is connected or disconnected during a zero crossing of the mains (line) voltage.

Title: Arrangement for producing a homogeneous, frequency-independent alternating magnetic field
Inventor: POTSCHKAT GUENTER
IPC: H01F7/20
Filed: 1988-01-28
Abstract: In order to produce a homogeneous, frequency-independent alternating magnetic field, two ring coils are used which lie on the same axis and whose separation is equal to the radius of the ring. The ring coils are electrically connected in series and are connected via leads to an A.C. voltage generator and a matched (reflection-free) terminating resistor. The leads have at all points the same wave impedance as the two ring coils. In order to make it possible to use generators and terminating resistors without conversion of the wave impedance, both ring coils, including their leads, are made from a coaxial cable.

Title: Container fitted with a closure
IPC: B65D47/10
Filed: 1988-04-05
Abstract: The fitting of removal apertures of containers, particularly made of sheet metal, with closures made of plastic is made less complex and easier if the edge region of the containers is pressed outwards in a tubular shape to form a container nozzle and its free end is shaped to point outwards and downwards so that the closure can be pressed into the opening of the container nozzle and can be clamped by an attachment ring which is pressed on, rests with its top side on the edge flange of the closure and, engaging with a tubular projection around the collar of the container nozzle, is supported against its lower edge regions after being pressed on by means of an undercut. In particular in the case of holding rings made of plastic, it has proved to be advantageous for these container nozzles, which have become deformed after disadvantageous deformation of the container, and their collar to be capable of adapting in a relatively stress-free state and thus still reliably to maintain the required sealing even after considerable deformation.

Title: Method for the location-resolved examination of superconducting materials by using magnetic (spin) resonance
Inventor: HAASE AXEL
IPC: G01R33/54
Filed: 1988-05-26
Abstract: In the present method for the location-resolved examination of superconducting materials, magnetic (spin) resonance data are picked up from the temperature bath surrounding the materials to be examined. By means of the superconduction in the material to be examined, the magnetic field lines are expelled out of the material (so-called Meissner effect), so that the magnetic field lines in the vicinity of the superconducting material become curved. Magnetic resonance data from the temperature bath surrounding the material, for example liquid nitrogen, are therefore altered in the vicinity of the superconducting material. By picking up location-resolved magnetic resonance data, therefore, the spatial distribution of superconduction in a material can be examined. The spatial structure can therefore be examined, particularly in materials which are spatially structured and consist of regions having superconducting and non-superconducting materials. The present method is suitable above all for the examination of high-temperature superconductors.

Title: Drive assembly of a motor vehicle with a connecting pipe between the engine-transmission unit and a remotely situated axle transmission
Inventor: BOLL WOLF DR ING
IPC: B60K17/00
Filed: 1988-07-05
Abstract: In order to isolate the vibrations occurring in the individual parts in a drive assembly of a motor vehicle, in which the engine-transmission unit and an axle transmission, situated remotely therefrom, are connected to one another by way of a connecting pipe surrounding the drive shaft, the connecting pipe is elastically supported in relation to the engine-transmission unit and/or the axle transmission. The elastic bearing is achieved by individual filler elements, each positively enclosed in the connecting area. In the event of a vehicle impact, the connecting pipe at the elastic tie points can plunge into the engine-transmission unit and/or the axle transmission, consuming deformation energy. The nature of the setting of the elastic filler elements helps to increase the deformation energy required for absorption of a part of the impact energy.
