Patent EP-0403982-A2 (EP)
Inventor: SAKAMOTO OSAMU
IPC: F02M69/10
Filed: 1990-06-15
Abstract: A two cycle crankcase compression internal combustion engine (11) including an air/fuel injector unit (29) for injecting fuel and air into the engine (11). Compressed air is delivered to the fuel/air injector unit (29) from an air compressor (36) and a heat exchanger (45) is provided in this line for cooling the air. The cooling is sufficient to cause condensation of any water vapor in the air and the condensate is drained from the system after the engine (11) is stopped through an electrically operated valve (49). This valve (49) also serves to reduce the pressure of the air in the system when the engine (11) is stopped so that fuel and air will not be discharged if the fuel/air injector unit (29) is removed when the engine (11) is shut down for servicing.

Abstract: An optical device is disclosed which provides wavelength multiplexing/demultiplexing utilizing a plurality of focusing Bragg reflectors (14,18,22,26). Each Bragg reflector includes a plurality of confocal (i.e., common foci) elliptical grating lines, with the exit/entrance ports of the input/output waveguides (12,16,20,24,28) located at the foci of the ellipse. By virtue of the elliptical design, the signal propagating outward from the exit port of the input waveguide (12) will be reflected by the appropriate Bragg reflector and focused into the entrance port of the appropriate output waveguide (16,20,24,28). When each Bragg reflector exhibits a different ellipticity, but shares one common focal point, optical multiplexing/demultiplexing may be achieved. Optical filtering may be achieved when all Bragg reflectors are designed to have common foci.

Abstract: A pneumoperitoneal needle (1) is described which comprises a hollow needle (2) for penetrating a body cavity and a hollow obturator (3) having a blunt tip (30) and through which a fluid may be transferred to and from the body cavity. The obturator (3) is mounted within the needle (2) and is linearly movable between a first position in which the blunt tip (30) of the obturator (3) extends beyond the tip (40) of the needle (2) and a second position in which the tip (40) of the needle (2) extends beyond the tip (30) of the obturator (3). There is also biassing means (7) which biasses the obturator (3) to the first position and the biassing means (7) is such that during penetration of the body cavity the resistance is sufficient to overcome the biassing means (7) and move the obturator (3) from the first position to the second position. After the body cavity has been penetrated the obturator (3) returns to the first position under the action of the biasing means (7). The obturator (3) is rotatable within the needle (2) and has through its wall at least two apertures (31, 32) adjacent to the tip (30) of the obturator (3) so that when the obturator (3) is in the first position fluid may pass through at least one of the apertures (31, 32) irrespective of the orientation of the obturator (3) relative to the needle (2). There is also a visual indicating means (5, 6) which indicates whether or not the obturator (3) is in the first position.

Abstract: An interconnect strip is provided for effecting electri­cal interconnection between pluralities of conductor pads disposed on circuit boards or the like in a high density configuration. The strip is fabricated from a polymer film carrier (10,30) having laminated thereon a metal foil with preselected spring properties. After lamination, lithographic techniques form a series of electrically isolated metallic beams (20) on the carrier. Additional chemical processing removes portions of the carrier at opposing sides of the strip to expose opposing ends of the beams which extend beyond the carrier parallel to one another in opposing directions out­wards from the carrier. By urging the pads towards respective beam ends of the strip disposed between the pads until mating engagement therewith, a plurality of electrical interconnec­tions are established through the beams. Flexural properties of the strip provide a low insertion force connection for a high density of conductors wherein the spring action of the strip assures favorable contact forces to the pads. The exposed film side of the strip may also be metalized and provided with beams or interconnected to beams on opposing side of the film by vias thereby providing a ground plane.

Title: Tertiary amine catalysts for polyurethanes
Inventor: CASEY JEREMIAH PATRICK

Filed: 1991-05-07
Abstract: The invention pertains to tertiary amines used as catalysts for the preparation of polyurethane foams prepared via the catalytic reaction of a polyisocyanate with a polyol in the presence of blowing agents, etc. The tertiary amine catalysts are prepared by reacting an olefinic nitrile with aliphatic polyol having at least secondary hydroxyl functionality in a ratio less than stoichiometric for providing cyanoalkylated polyol having residual hydroxyl functionality. The resulting cyanoalkylated polyol then is reacted with a secondary amine under conditions for effective reductive alkylation. 
     The tertiary amine catalysts, because of residual secondary hydroxyl functionality, provide for uniform dispersion within a polyurethane formulation; they provide for additional or extended pot life in polyurethane formulations at temperatures below reaction condition, and they are bound by reaction on cure.

Abstract: A method and means is described for writing data on a recording medium, such as a disk or tape, containing servo samples in such manner that the number of servo samples is increased with a minimal increase in overhead (non-data) regions. The tracks on the medium are divided into a plurality of maxi sections, each of which contains all fields with servo and associated overhead information and also a data field. At least one micro servo section containing only a portion of said information is located within each data field. 
     As each micro servo section passes by an associated recording head, writing and reading of data is temporarily interrupted, but resumed when the micro servo section moves beyond the head, in such manner as to require minimal resynchronisation of said data during reading. 
     Using a phase continuous clock, data is written in both portions of a data field to either side of each micro servo section in one pass of the disk or tape relative to the head. The micro servo sections contain no timing reference address mark and require no data encoder/decoder flush or synchronisation byte to resume reading in the portion of the data field following each micro servo section.
