Patent EP-0237282-A3 (EP)
IPC: B41J2/20
Filed: 1987-03-05
Abstract: A viscoelastic and ink-immiscible fluid is used to form a 
membrane over the ink orifice of a drop-on-demand, press­
ure pulse ink jet head. The membrane lies in a plane 
perpendicular to the direction of emission of ink drops, and 
provides a barrier between the ink orifice and the external 
atmosphere. Evaporation of the ink, or entry of contaminants 
including air into the ink, is thus inhibited. The elimination of 
evaporative clogging then permits the use of a smaller 
orifice. Wetting of the exterior surface of the ink jet head by 
the flow of ink through the ink orifice is also inhibited, thus 
making possible the production of more uniform ink drops 
that will emerge in a constant direction. The elastic property 
of the membrane permits the passage of an ink drop 
therethrough, followed by the closing up of the membrane. 
The viscous property of the membrance permits it to absorb 
any energy of a pressure pulse that is not consumed in 
ejecting an ink drop, thus inhibiting the occurrence of 
pressure oscillations that could cause either variations in the 
speed of ejected ink drops or the apearance of satellite ink 
droplets.

Abstract: An air condition monitor unit for monitoring the 
temperature and/or relative humidity of the ambient air. It 
comprises an air temperature sensor (60 or 114) and/or a 
relative humidity sensor (62 or 112) and a plurality of 
memory means (78 or 104) capable of retaining set values 
of respective thresholds. These set values comprise the 
maximum and minimum acceptable values of air temperature 
and/or relative humidity. Warning means (72 or 124) are con­
nocted to the sensor (60, 62, 112 or 114) and the plurality 
of memory means (78 or 104) to provide a warning signal in the 
event that the actual value of the variable indicated by the 
sensor (60, 62, 112 or 114) passes a corresponding one of 
the retained values in the plurality of memory means (78 or 
104). Membrane switch means (44, 46) are connected to the 
plurality of memory means (78 or 104), operation of which 
switch means changes a set value retained in the plurality of 
memory means. Second membrane switch means (42) are 
connected to the first switch means (44, 46) and the plurality 
of memory means (78 or 104), successive operation of which 
second switch means changes the memory means for the time 
being addressed by the first switch means (44, 46) from one 
memory means to the next in a predetermined cycle.

Abstract: Acquisition of drug resistance of tumor cells in 
patients subjected to chemotherapeutic treatment is monitored by 
periodically withdrawing fresh tumor cells from the patient and 
determining the  in vitro  sensitivity of the withdrawn cells to 
the administered drug. This determination can also be used to 
diagnose relapse in a patient receiving chemotherapy. By making 
repeated withdrawals of tumor cells and repeated determinations 
of  in   vitro  sensitivity of the withdrawn cells to the 
administered drug and by comparing the sensitivities determined, 
chemotherapeutic protocols can be modified.
Patent EP-0275121-A3 (EP)
IPC: F02C7/143
Filed: 1988-01-15
Abstract: The cycle includes water-injection, steam-­
injection, recuperation (or regeneration) and waste-heat 
boiler heat recovery in an arrangement that provides 
high thermal efficiency, flexible operation in a 
cogeneration plant and favorable capital cost in 
relation to thermodynamic performance when compared to 
currently practiced cycles. In the present cycle, the 
sensible enthalpy of the exhaust gases between turbine 
exit and stack is used to simultaneously and in-parallel 
heat both air and water/steam. A smaller amount of 
water is boiled than in the known Cheng cycle, in which 
the exhaust heat is used only to heat water/steam. 
Thus, the latent heat exhausted at the stack in the 
present cycle is lower than that for the Cheng cycle 
resulting in higher efficiency.

Title: Procedure for the determination of the absorption of liquid of powdery solid matters
IPC: G01N11/14
Filed: 1988-08-18
Abstract: A process for measuring the liquid absorption capacity of a powder includes the step of spraying a liquid in the form of a spray cone at a constant throughput from at least one spraying device onto a powder being stirred in the mixing chamber of a mixer, the powder filing between 10 to 80% of the mixing chamber. The torque of the stirrer of the mixer is measured both before and during the spraying step, and from this measurement both a maximum level of the torque and the time difference between the beginning of the spraying step and the time when the maximum level is reached are determined. An amount of liquid absorption of the powder is then determined based upon the liquid mass which is sprayed during that time difference.
