Title: Ink jet printer
Inventor: IWASAKI KYUHACHIRO
IPC: B41J2/195
Filed: 1983-05-20
Abstract: In an ink jet printer, some of the ink droplets which have been ejected from a nozzle of an ink ejector head and have not been used for printing are caught in a collector and fed to an ink supply source via an ink circulation path for re-use. The ink is drawn off partially in order to remove it while fresh ink from the ink supply source is supplied proportionally to the removed quantity of ink in order thus always to maintain the viscosity of the ink at a correct value. To remove the ink, a solenoid-actuated three-way directional valve is opened periodically for a predetermined time, and ink droplets ejected from the nozzle are deflected and collected by a collector which is independent of the first collector. The quantity of ink removed is recorded by means of the pressure of ink which has been fed to the nozzle and/or by means of an ink temperature in the vicinity of the nozzle.

Patent DE-3333421-A1 (DE)
Title: Rotary piston machine
Inventor: OSTERBURG GUENTER
IPC: F02G5/00
Filed: 1983-09-16
Abstract: The aim of this invention is to lower the fuel consumption of internal combustion engines and at the same time reduce their impact on the environment. The object is to be achieved by means of a rotary piston machine with uniformly rotating piston rotors which employs the Joule cycle with heat recovery. Integrated into the rotary piston machine is a compression part and an expansion part. Since, during expansion, the expansion piston rotor is subjected to hot working gases only over half a revolution, the thermal loading is lower than that in a gas turbine. The possibility of using ceramic materials is provided by this advantage as regards cooling. The invention can also be used as a combined expansion/compression machine, a compressor, an expansion machine, a combined unit for many technical installations, e.g. heat pumps, a cooling and air-conditioning system or a supercharger for an internal combustion engine.

Title: Process and equipment for producing a synthesis gas consisting of hydrogen and carbon monoxide
Inventor: BARIN IHSAN PROF DR
IPC: C10J3/57
Filed: 1983-09-24
Abstract: The invention relates to a process and equipment for producing a synthesis gas consisting of hydrogen and carbon monoxide by gasification of carbonaceous materials, in particular coal, in an iron bath reactor. Synthesis gases which are produced by conventional processes must be subjected to extensive purification processes, for example a separation from sulphur dioxide, and, due to their unfavourable hydrogen/carbon monoxide molar ratio, cannot be further used directly. Utilising novel technical aspects and allowing in particular for economic points of view, however, the process according to the invention enables a synthesis gas to be produced which, by enrichment with additional hydrogen, for example from a high-temperature electrolysis, has a molar ratio of two mol of hydrogen to one mol of carbon monoxide and can therefore be used directly as a raw material for the methanol synthesis. <IMAGE>

Title: Sensor key with pressure point and contactless electrical signal transmission
Inventor: NAUJOKS ROLAND DIPL ING
IPC: H03K17/97
Filed: 1984-03-15
Abstract: It is known to use a ring of soft-magnetic amorphous material for electronic sensors, for example for keyboards. When the ring is deformed, its soft-magnetic characteristics change, which can be utilised for generating a voltage pulse. The elastic behaviour of the amorphous material allows the ring tape core (1) to be used at the same time as a spring for pressing up the key body (10). A special embodiment now allows a spring characteristic with a pressure point to be achieved by means of only one tape of amorphous material, which is wound to form a ring (5) and which has a protruding tape end (4), so that an unambiguous impulse transmission is made possible (Figure 2). <IMAGE>
