Title: Fibre hopper feed - has process computer to give constant material weight and volume to be fed to carding
Inventor: GOCHARD CHRISTIAN
IPC: D01G23/04
Filed: 1989-04-26
Abstract: The hopper feed and scales assembly, to deliver fibre material to a carding appts., has an input for the adjustment or nominal values for the required spread mass (D) and nominal weight at the feed table step. The actual weight of the material on the feed table is measured for the reading to be passed to a process computer together with the speed measurement of the web for control of the extracted web from the hopper feed with scales, and the amount of material taken between two preset time points. The data is also displayed. ADVANTAGE - The system continually weighs the material with simplified reactive control to give a virtually constant material mass taken off according to predetermined adjustment and nominal values.

Title: Cooling device for drawn light-conducting fibre - has internal body which can be opened into two halves surrounded by outer coolant body
Inventor: LEPPERT HANS-DETLEF DR
IPC: F28F3/12
Filed: 1989-06-19
Abstract: Apparatus for cooling a drawn light-conducting fibre (5) comprises a hollow body which can be opened up by rotating two halves (11,12) about hinge (13).

Retention of the insert during injection is by holding pins which may be removed during the injection stage.
Patent DE-3932428-A1 (DE)
Inventor: KOSTER NORBERT H L DR ING
IPC: A61B5/00
Filed: 1989-09-28
Abstract: The invention relates to a device for accurately measuring the distribution of local, physical values at a site which is normally inaccessible (for example in living tissue) and for wireless transmission of the measurements and of an identification sign for the transponder transmitting the measurements to an evaluation unit positioned outside the measurement site. By coordinating the measurement to the site of the transponder, the distribution of the physical values to be measured can be determined. Thus, it is possible, for example, to determine the temperature distribution in a tissue fragment, the bending load at different positions of bones, or the body temperature of various laboratory animals in a cage. Since the energy supply is wireless and is effected by means of an electromagnetic field, the service life of the transponders is not limited by exhaustable energy sources. <IMAGE>

Patent DE-4003113-A1 (DE)
Inventor: BENECKE WOLFGANG DR ING
IPC: H02K37/00
Filed: 1990-02-02
Abstract: The invention concerns motors in which the torque is produced not by magnetic fields but by dielectric forces. Fields of application are microelectronics and micromechanics. The rotors consist of several dielectrics (2a, 2b) arranged in sectors or disks or which partly or completely surround each other. These motors can be miniaturized to a few  mu m in size. They are characterized by slow to medium rotational speeds, short start-up phases (ms range and less), extremely low current consumption, simple construction and high running constancy and require virtually no maintenance. The rotation characteristic curve (rotation as a function of field frequency) can be freely chosen within wide limits by variation of the rotor dielectrics (2a, 2b).
