Patent CA-2062141-A1 (CA)
Inventor: RUEEGG WALTER
IPC: G01N15/06
Filed: 1992-03-02
Abstract: In a method and a device for measuring the concentration of particles present in a gas, in which a gas stream is guided past a UV light source, the particles are ionized and filtered out and the resulting ionic current is measured, the gas flow required is produced by thermal convection using an internal or external heat source. A suitable internal heat source in this context is, for example, the UV lamp (2) itself, which heats the gas via a radiation absorber (5).      The elimination of a mechanical pump reduces the space requirement, power consumption and susceptibility to faults of the measuring arrangement.

Title: Measuring catheter and method for measuring the degree of oxygen saturation of flow rate of blood
Inventor: IWASAKI HITOSHI
IPC: A61B5/00
Filed: 1991-05-17
Abstract: ABSTRACT         Disclosed is a measuring catheter having light-emitting and light-receiving optical fibers disposed within the catheter, the end faces of the light-emitting and light-receiving optical fibers being fixed to the outer sidewall of the catheter so that they are opposite to each other with a predetermined space therebetween.         The degree of oxygen saturation or flow rate of the circulating blood can be determined in real time by supplying both measuring light and reference light to the light-emitting optical fiber of this catheter and measuring the transmittances of the two types of light that are collected by the light-receiving optical fiber after having passed through the blood present in the gap between the end faces of both optical fibers.

Title: Optical amplification system
Inventor: NAKAMURA KAZUNORI
IPC: H04B10/293
Filed: 1992-05-19
Abstract: An optical amplification system capable of operating without being affected by the waveform of the incoming optical signal is provided for amplifying the optical signal in its optical waveguide by the effect of stimulated emission of a fluorescent substance induced by pumped light. According to a first aspect of the invention, an optical amplification system turns on its pumping source 8 when there is an optical signal s1 in the optical waveguide 5 whereas the pumping source 8 is kept off as long as no optical signal s1 is found in the optical waveguide 5 so that, when the pumping source 8 is turned on, pumped light from the pumping source 8 is fed to the optical waveguide 5 with a delay of time relative to the incoming optical signal s1. According to a second aspect of the invention, the inside of the optical wave-guide 5 is constantly kept under an excited condition so that, when no optical signal s1 is found in the optical waveguide 5, dummy light s3 is fed to the optical wave-guide 5, whereas no dummy light s3 is fed to the optical waveguide 5 once an optical signal s1 is introduced to the optical waveguide 5. With such an arrangement, since no optical amplification takes place at the rising edge of an incoming optical signal and hence the operation of optical amplification is not dependent on the waveform of the incoming optical signal, a safe and stable optical amplification system can be established.

Title: Induction of an antigen-specific t-lymphocyte response
Inventor: MELIEF CORNELIS J M
IPC: G01N33/68
Filed: 1992-05-26
Abstract: Induction of an antigen-specific T-lymphocyte response in a T-lymphocyte culture, e.g. a primary cytotoxic T-lymphocyte(CTL) response, by loading antigen-presenting vehicles which carry empty MHC molecules with an antigen-derived T-cell-immunogenic MHC-binding peptide, culturing T-lymphocytes in the presence of the peptide-loaded antigen-presenting vehicles under specific T-lymphocyte response-inducing conditions. Optionally, an antigen-specific T-lymphocyte is isolated from the resulting culture and cultured. The process can be used for preparing CTL which are specific for viral or other foreign antigens, or CTL which are specific for autologous peptides. The process can also be used for the identification of peptides that are capable of binding to MHC and inducing a T cell response.

Such shirred pants are readily and economically fabricated from four longitudinally extended quarters per pant leg, having an arcuate plane shape with a sideseam side of a standard length of the pants or an inseam side of a standard under-crotch length, as a short arc, and with a centerline side of a length ranging 110-160% of the standard length, as a long arc.  Front quarters and rear quarters are seamed together, respectively, at the centerline sides, to form front and rear halves of a pant leg which are then shirred along the entire length of the centerline to gather the long arc substantially to the standard length under a tensionless condition. With the thus shirred halves, the pants are made up according to a usual procedure.
