Patent EP-0312101-A3 (EP)
IPC: A61M39/22
Filed: 1988-10-14
Abstract: An autotransfuser (10) that includes, in a single receptacle (15), a pair of chambers (20, 30) separated by a common wall (16). Each receptacle can alternately perform, a blood infusion or blood collection function. Each chamber includes at least three inlets/outlets, a blood inlet (24, 34), a blood outlet (25, 35) and an air inlet means (22, 32). In some embodiments of the invention the air inlet means serves alternately to couple either an air or a pressure source on the one hand or a vacuum source on the other hand to the corresponding chamber. In other embodiments of the invention, the air inlet means comprises a vacuum inlet and a separate air or pressure inlet. A disk like device (40) or valve manifold is arranged for rotatable movement adjacent the inlets/outlets. The disk like device includes four channels, one for each of air or pressure (47), vacuum (46), blood collection (48) and blood infusion (49). Each channel includes a port for coupling to external tubing and at least one channel end. The channel ends are located in the disk like device so that by rotating the disk like device to two distinct positions, one or the other of the functions can be performed by each chamber. A blood valve is also disclosed which has a float element (104) having a specific gravity which allows it to float in a pool of human blood and a significant closure force in excess of about ten to fifteen grams.

Patent EP-0360952-A3 (EP)
Title: Device for creation and control of indication signals
IPC: G05B19/045
Filed: 1989-02-02
Abstract: An indication-signal generator is used for controlling switching-on and -off routines for a device (G) connected to a power supply (SV). As a result, the device (G) is protected against voltage fluctuations and correctly taken into and out of operation. A switching-on/-off control (EA) starts a counter (Z) by means of which the indication signals stored in a storage element (SE) are read out. They are transferred to the device (G) via signalling lines (ML). A clock generator (TG) determines the duration of the individual counter steps as a timing element. One routine consists of a plurality of counter steps. The sequence of a routine is changed by changing the storage content. <IMAGE>
Patent EP-0334034-A3 (EP)
Title: Control method to prevent surge of a centrifugal compressor
IPC: F04D27/02
Filed: 1989-02-21
Abstract: In the case of known control methods, faults which give rise to intervention by the governor, for safety reasons operating at increased proportional boosting, result temporarily in reduced surge reliability of the compressor and in prolonged, periodic pressure fluctuations in the consumer mains post-connected to the compressor. The new control method is intended to avoid these disadvantages. 
<??>The new control method is characterised in that in the event of a discrepancy between the position (ya) of the venting valve (21) and the control variable (u) of the governor (5) exceeding a predeterminable limit, the control variable (u) of the governor (5) is readjusted to the respectively current position (ya) of the venting valve (21) by a readjusting circuit (9). In this way transient processes and hence related reductions in the pumping reliability and longer pressure fluctuations are avoided. 
<??>The new method is suitable in particular for the control of large turbocompressors, for example for blast furnace blast generation, air separation, fertilizer manufacture or fluidised bed generation for petrochemical processes.

Abstract: An absorbent article (110) comprising an outer layer (112), a 
liquid-permeable inner layer (114), an absorbent body (116) 
positioned between said inner (114) and outer (112) layers, 
and an array of adhesive arranged to secure one or more of 
said layers (112, 114) to said absorbent body (116) wherein 
said adhesive array is composed of a plurality of juxtaposed, 
substantially continuous, semi-cycloidal patterns (90) of 
adhesive exending substantially along a longitudinal dimension 
of said article (110).  
     Methods and an apparatus are described for depositing a 
pattern of material (11), such as hot-melt adhesive, onto a 
substrate (14), via a supplying mechanism (10) for forming a 
first and at least a second substantially continuous stream of

forming a plurality of gas streams. The gas streams have 
selected velocities and are arranged to entrain the material 
streams to impart a swirling motion to each of the material 
streams as it moves toward the substrate (14). A transport 
mechanism (15, 16) moves the substrate (14) relative to the 
supply mechanism along a selected machine direction (27). The 
material stream is controlled in a selected path toward the 
substrate (14) and deposits the material in adjacent semi-­
cycloidal patterns (90) on the substrate (14) while a selected 
cross-directional positioning of one or more of the deposited 
patterns is closely controlled.

Title: Apparatus for carrying out decoupling control of a t-die
IPC: B29C48/31
Filed: 1989-08-31
Abstract: In an apparatus for use in carrying out 
decoupling control of a T-die which has a pair of lip 
portions with a gap extended between the lip portions 
and with the lip portions divided into a plurality of 
zones individually driven by driving devices, 
respectively, a processing circuit individually controls 
the driving devices by the use of a predetermined 
decoupling control algorithm. The predetermined 
decoupling algorithm is given by a plurality of desired 
displacement vectors of the gap for the respective zones 
and a decoupling control matrix defined by inverse 
number of products of a command value/driving pressure 
converting matrix (Kp) and a driving pressure/ 
displacement converting matrix (Kα). Alternatively, the 
decoupling control matrix is repeatedly modified with 
time to decrease a difference between the desired gap 
displacement (Δy) and the measured gap displacement 
(Δy m ). Each command voltage value vector Δu of the 
command value/driving pressure converting matrix is 
compensated by the use of a figurative inherent error of 
the lip structure.

temperatures is allowed to flow in the above series circuit. 
Accordingly, a malfunction of the above npn transistor is 
prevented. Consequently, an integrated circuit operable 
even under high temperatures is achieved.
