Abstract: An appts. for forming an image on a receiver sheet (P) comprises an image recording element (2), a unit (9) for forming a latent image on the recording element (2), a unit (4) for developing the latent image on the recording element (2) by means of a developer powder (T), a unit (5) for transferring the developed image to the receiver sheet (P), a unit (7) for cleaning the recording element by removing residual developer powder remaining on the recording element (2) after transfer of the developed image to the receiver sheet (P) by the transfer unit (5) and a housing (1) in which the units (9), (4), (5) and (7) are mounted. The housing (1) also contains a means (21,22,23,24) for catching the developer powder scattered by or falling from the developer unit (4), the transfer unit (5) and/or the cleaning unit (7), and a means for chemically treating the developer powder collected. USE/ADVANTAGE - The units for trapping the stray powder are pref. in the form of plastic or metal containers contg. a sponge or foam type material impregnated with a plasticiser cpd. which is capable of softening or melting the binder resin used in the toner, so that the trapped toner powder becomes adherent and sticks to the powder trap.

Patent DE-4012080-A1 (DE)
Inventor: MAREK JIRI DR ING DR
IPC: G01F1/684
Filed: 1990-04-14
Abstract: Proposed is process for manufacturing a sensor, in particular an air-mass sensor, at least one sensor element being formed from a wafer. The sensor element is separated from the wafer and attached to a substrate. At the same time as the structure of the sensor element is being formed by means of anisotropic etching, the outer edges of the sensor element are anisotropically etched so that the sensor element is only joined to the wafer from which it is produced by thin strips which are cut through in order to separate the sensor elements. At least one aperture is created in a second wafer by anisotropic etching, the dimensions of the aperture corresponding to those of the sensor element. In order to assemble the sensor, the sensor element is inserted in the aperture in the second wafer.

Patent DE-4027801-A1 (DE)
Inventor: HOCHREUTHER KARL
IPC: H01H9/24
Filed: 1990-09-01
Abstract: In multimeters having a plurality of input connections there is a danger of the measuring conductors being incorrectly connected in such a manner that the setting of the measurement range switch does not correspond to the input connections to which contact is made. In order to avoid damage which may be caused by making an incorrect contact to the input connections, an electrically and/or mechanically acting disabling device is coupled to the measurement range switch for permitting a disabling of particular input connections. The disabling is carried out in such a manner that contact can always only be made to that input connection for receiving a test signal through the measuring conductors, to which a measurable variable is assigned that corresponds to the measurable variable set with the measurement range switch.
