Title: Potentiometric relaxation analysis using a selective electrode system
Inventor: KLEIN KARL-DITTMAR DR
IPC: C12Q1/00
Filed: 1994-06-16
Abstract: The concentration of a specific substance is determined in the potentiometric relaxation procedure of DE4100727, with single or twin electrodes. Interference from deposits on electrodes or their coatings, is prevented by enclosing a reaction space around them, with a semipermeable membrane, esp. for long term operations. This is filled with an auxiliary solution, pref. a filtrate of the solution under investigation, and as required, a selective biological component, e.g. an enzyme.  The diffusion-process or layering, and subsequent relaxation measurement, are kept short, by limiting the duration of the applied potential difference. Recovery time between successive relaxation measurements is made sufficiently long, that the equilibrium between the solution in the reaction space and the solution to be analysed, re-establishes itself.

Title: Vacuum-switch contact arrangement
Inventor: SLAMECKA ERNST PROF DR TECHN
IPC: H01H33/664
Filed: 1994-06-23
Abstract: Individual current paths 78, which are in the form of circular-ring cut-outs and, in consequence, produce an overall current path in the form of a circular ring, are produced in the load-bearing body wall by means of azimuthal gaps 8 (first gap) in the wall of a load-bearing body 3 which is designed as a general hollow body of rotation and has a gap profile at least approximately parallel to a contact and electrode disc 7 in combination with gaps 9 (second gap) which are in each case connected only to one of the gap ends in the direction of the contact and electrode disc and are generally inclined with respect to the switching element axis. An axial magnetic field which is distributed virtually uniformly over the electrode surface and acts in a correspondingly optimum manner can be produced in a particularly simple manner using such a current path without any azimuthal interruption in the effective axial magnetisation. <IMAGE>

Patent DE-4438936-A1 (DE)
Title: Ink jet printer
Inventor: MITANI MASAO
IPC: B41J2/14
Filed: 1994-10-31
Abstract: An ink jet printer has an ink channel which is filled with ink, a nozzle which moves the ink channel into fluid connection with the external atmosphere and a thermal resistor which is provided in the ink channel near to the nozzle. A voltage pulse is applied to the thermal resistor, in response to which the thermal resistor heats up rapidly so that some of the ink in the ink jet channel is rapidly vaporised by undercooled boiling which is caused by alternating bubble formation, in order to form a bubble, the expansion of the bubble causing an ink droplet to be ejected from the nozzle. In this thermal resistor boiling begins within 2  mu sec after the application of the voltage pulse has begun. The voltage pulse is applied to the thermal resistor for a period of 3  mu sec or less. The bubble which is produced by applying the voltage pulse to the thermal resistor disappears without the thermal resistor producing secondary bubbles. The bubble which is produced by the application of the voltage pulse to the thermal resistor disappears within 11 seconds after the application of the voltage pulse has begun. The energy required to produce the bubble is 4  mu J/50 x 50  mu m<2> or less.

Patent DE-4443812-A1 (DE)
Inventor: RANDOLL HELMUT DR DR RER NAT
IPC: G01K7/42
Filed: 1994-12-09
Abstract: In a process for forming a signal (Tan) for the suction air temperature of an internal combustion engine (100), the signal (TAn) for the suction air temperature is derived from a signal (TMot) for the temperature of the internal combustion engine (100) and from a signal (TU) for the ambient temperature. A correction factor (K) dependent on a signal (mL) for the quantity or mass of air sucked in by the internal combustion engine (100) and/or on a signal (v) for the vehicle speed is taken into account. In order to allow the suction air temperature to be simulated as precisely as possible even in non-stationary operation conditions, the signal (TAn) for the suction air temperature is filtered and different time constants (ZK) may be selected for the filter depending on whether the suction air temperature increases or decreases.
