Title: Process to extract nitrogen and oxygen from air by fractionated cryogenic distillation with lower energy requirement
Inventor: VOIT JUERGEN
IPC: F25J3/04
Filed: 1999-07-16
Abstract: Oxygen and nitrogen are produced by the fractionated cryogenic distillation of air in a rectification system consisting of a pressure column and a low-pressure column. Oxygen and nitrogen are produced by the fractionated cryogenic distillation of air in a rectification system consisting of a pressure column (9) and a low-pressure column (10). Process air (1, 5, 7) is surrendered to the pressure column (9). A liquid fraction (16) containing oxygen is drawn from the pressure column (9) and charged into the low-pressure column (10). Gaseous nitrogen (24) from the low-pressure column (10) is at least partly condensed by indirect take-up of heat a cooling fluid (19, 21). Nitrogen is generated as a pressurized gaseous product (12, 15, 35) from the pressure column. A second portion (200, 201) of the process air (1, 5, 7) is introduced into the low-pressure column (10).

Title: Melt spinning assembly has a filament cooling channel at each spinning station with an air flow generated by a single underpressure fan unit and an eddy tube to take the emerging air flows for a consistent flow at each station
Inventor: NITSCHKE ROLAND
IPC: D01D5/092
Filed: 1999-07-29
Abstract: The melt spinning assembly, with a number of spinning stations to spin filaments from molten polymers, has a cooling channel for each spinning station. An underpressure system generates a flow of coolant air through all the channels, with an equal flow in each.  The coolant air flows are generated by a single vacuum fan unit, and the air flows through the cooling channels are drawn out evenly by suction through a single eddy chamber. The separate extracted coolant air flows pass at a tangent into the eddy tube. An Independent claim is included for an assembly where the coolant flow channels (4) open into a flow smoothing unit (7) which ensures that an equal coolant air flow passes through each cooling channel (4) at each spinning station (2).

IPC: A61M5/32
Filed: 2000-06-21
Abstract: A syringe (10) for drawing blood from a patient, the syringe having a
barrel (12) with a restricted free end (12a) and a needle assembly (14) releasably secured
to the restricted free end. A plunger (16) is inserted into the barrel through an opposed
end (12b), and retraction of the plunger within the barrel, away from the restricted free
end, is effective to withdraw blood from the patient when a needle (14a) with a sharpened
free end of the needle assembly is appropriately inserted into the patient. The syringe 10
is also provided with an annular needle guard (18) that surrounds the barrel and is
slidable with respect thereto between a first position, in which the needle guard does not
surround the needle, and a second position, in which the needle guard does surround the
needle, to prevent the tip of the needle from injuring a person handling the syringe during
times when the syringe is not being used to withdraw blood from a patient. The needle
guard is made from a semi-rigid, transparent organic material, and has a diametrically
opposed pair of inwardly extending projections (18a) that engage a diametrically opposed
pair of outwardly facing recesses (14a) in the needle assembly when the needle guard is
in its first position to prevent it from inadvertently moving to its second position. Hand
squeezing of the needle guard along an axis extending perpendicularly to an axis between
the projections is effective to disengage the projections and recesses, whereupon relative
motion can occur between the barrel and the needle guard. This will occur, by gravity, if
the syringe is held in a substantially vertical position with the needle up, whereupon the
barrel will fall relative to the needle guard until the second position of the needle guard is
reached.

Abstract: To one port of a 2x2 optical coupler (3a) are connected an
attenuator (4a), an optical grating (5a) and an optical terminator (6a) in cascade. The
optical coupler causes an incident light beam to be branched into two
branched beams, and outputs one branched beam and a beam of a
specific wavelength from different respective ports. An optical loop-back
circuit is provided with two of such optical couplers and an optical fiber
for connecting them. One of the optical couplers is installed in an upward
optical fiber transmission path (2a) and the other in a downward optical fiber
transmission path (2b). From a main signal light and a monitoring signal
light, the optical loop-back circuit returns to a terminal station only the
monitoring signal light via the opposite optical fiber transmission path. As
a result, the terminal station can monitor the optical fiber transmission
path and so forth at the same time as receiving the main signal light.
