Patent EP-0253265-A1 (EP)
Inventor: HEINLE GEORG DIPL-ING
IPC: H02M5/45
Filed: 1987-07-06
Abstract: For setting in operation a converter drive for an asynchronous machine with an intermediate-current link and phase-sequence quenching, the commutations in the inverter are synchronized with the commutations in the controlled rectifier and/or all commutating capacitors are discharged before the start-up and/or the direction of commutation is cyclically changed during the startup. This makes it possible to start up the converter also if the intermediate-link current has gaps, and the asynchronous machine is loaded only with hunting torques.

Abstract: Metal is deposited on a substrate by irradiating at least a portion of the substrate in the presence of a catalytic metal-containing compound with radiation sufficient to decompose the catalytic metal-containing compound and thereby deposit the catalytic metal on the substrate, and then contacting the catalytic metal with an electroless plating solution containing the metal to be deposited on the substrate. Products produced by the method are useful in the manufacture of electronic components including printed circuit boards, semiconductor devices and the like.

Abstract: An integral heat pipe for transferring heat away from electronic components (12) is disclosed. The heat pipe comprises at least one electronic component mounted to a substrate (14). A condenser cap (18) is fastened over the substrate to define a sealed pipe chamber (20) around the electronic component. The top of the condenser cap facing the component is a condenser surface (26) and is provided with a number of parallel fluted sections (28). Each fluted section has parallel vertical sidewalls (30) and a semi-circular top section (32). A multi-layered fiberous, porous, wick (36) is located between the condenser surface flutes and the top of the electrical component. The top of the component may be provided with a number of parallel grooves (15) exposed to the wick. The pipe chamber (20) is filled with a two-phase working fluid (33). The heat generated by the electrical component causes the liquid fraction of the working fluid adjacent the component to evaporate. The vapor travels to the fluted condensing surface (26). The latent heat of vaporization is removed from the vapor so it recondenses and returns to the bottom of the module to repeat the heat transfer cycle. The wick's capillary pumping action keeps the fluid distributed over the top surface of the electronic component. The grooved top surface of the electronic component exposed to the wick cause an inverted liquid meniscus to be formed over the component. This causes the liquid adjacent the top of the component to readily evaporate.

Abstract: The cuff is pressurised at a relatively high rate before the estimated maximum blood pressure value is almost attained. The rate is then reduced down to one required by that measurement so as to measure the maximum blood pressure value. To measure the minimum blood pressure value, the pressure is reduced quickly to a level a predetermined value above the estimated minimum blood pressure value immediately after completion of measurement of the maximum blood pressure value, and the pressure reducing speed is then reduced to actually measure the minimum blood pressure value.

Abstract: The invention provides a body liquid drainage device (9) particularly for urine, said device comprising a first liquid storage chamber (20) formed of a flexible plastics material and provided with an upper inlet (1) for body liquids, and a lower valved outlet (12) for body liquids. 
     A second liquid storage chamber (10) is operatively connected to the first liquid storage chamber (20) and is selectively fillable. Preferably said second chamber is moveable from a first position in which it is generally in parallel abutment with the first chamber thereby to overlie the same; to a second position in which it forms an extension of the first chamber. The device may be utilised in a lower capacity mode during daytime, and in a higher capacity second mode in non-ambulant times or during night-time. 
     This arrangement prevents invasive infections occurring because inter-connection between in-dwelling catheter and the drainage bags are infrequent.

Abstract: A process and system for supplying ink to an ink jet pen (10) wherein an off board ink supply (66,68,70,72) is provided remote from the pen, and ink is fed from this supply to the pen by capillary action created during an ink jet printing operation. The pen (10) includes a porous storage medium Fig. 3 which is initially filled with ink at a slightly negative head. However, this negative head increases during ink depletion from the storage medium and provides the capillary forces necessary to pull ink into the storage medium from the off board ink supply. The driving energy for this action is provided by current drive to a thin film printhead (38) of the pen, thus rendering the printhead multi-functional in purpose and simplifying the ink supply apparatus therefor. The use of an intermediate porous storage medium enables the ink supply system to accommodate large rates of changes in ink demand from the pen while still affording the user with a large ink capacity system in which disposable pens may be readily and easily replaced in a user­friendly operation.

Abstract: A distributed digital data 
processing system includes a 
plurality of nodes which com­
municate over a network. A 
node maintains one or more 
objects, each of which may be a 
file, that is, an addressable unit, 
in the system, such as a pro­
gram, database, text file, or the 
like, or a directory which may 
contain one or more files or 
other directories. One node 
maintains a naming service 
which associates each object in 
the system with one or more 
protocol towers. Each protocol 
tower identifies the object 
name and a series of entries 
each identifying a name for 
each of the protocol layers, 
along with the communications parameters and address information, to be used in communicating with the object. When 
a 
node requires access to an object maintained by another node, it first retrieves from the naming service the protocol 
towers 
for the object. The node also maintains a tower identifying the names of each of the protocols over which it can 
communi­
cate. The node then compares the protocol names in the retrieved protocol towers with the protocol names over which 
it 
can communicate. If the protocol names in a retrieved tower match the protocol names in the node's tower, the node 
uses 
the communications parameters and address information in future communications with the object. If the node is unable 
to identify a retrieved protocol tower which matches its supported tower or towers, it is unable to communicate 
with the 
object.

Abstract: The present invention relates to a process for the manufacture of a natural fish product from fish fillets and/or their parts without binders or the like, the protein myomeres of which are substantially undamaged. Fishcakes known from prior art have additives such as milk, thickeners and gelling agents and spices. However, the invention natural fish products, which do not contain binders or the like, yet still have a stable and aesthetic shape. Also they should be easy to handle during production, packaging and finally during consumption. This is solved according to the invention by a manufacturing process, characterised in that fresh and/or thawed fish fillets and/or fish parts, and optionally flavourings, are mixed individually with water in a free fall mixer at a temperature in the range from approximately -4 DEG C to +10 DEG C, and that subsequently the fish fillets and/or their parts are cooled back to approximately -4 DEG C (+/-4 DEG C), during passage through a nitrogen-filled freezing tunnel, and that the fish fillets and/or their parts are then transferred by a conveyor to a moulding chamber likewise cooled to a temperature of approximately -4 DEG C (+/-4 DEG C), where they are compressed in a mould at a pressure of 5 to 15 kg/cm<2>, particularly 10 kg/cm<2>.
