Title: Ultrasonic air-in-line detector for detecting entrained air in a medication infusion system
Inventor: KOENIG PAUL A
IPC: G01N29/032
Filed: 1991-04-04
Abstract: An ultrasonic air-in-line detection system for use in detecting entrained air bubbles in the fluid line of a disposable cassette mounted on a main pump unit is disclosed which can accurately detect entrained air bubbles in any type of fluid, whether clear or opaque. The system uses multiple windowing and air volume number weighting to determine when a threshold count of entrained air in a predetermined number of windows of material pumped occurs, with the alarm being sounded only when this threshold count of air bubbles is present in the multiple window volume.   The system of the present invention thus will detect entrained air while avoiding so-called nuisance alarms.

IPC: B42F15/00
Filed: 1991-07-23
Abstract: ABSTRACT OF THE INVENTION       Hanging folder rods are flat strips having notches or hooks at their ends for riding on the rails of a file support frame.  Notch depth is extended by long tips at the ends of the strip.  By contouring the notches, extensions, and end corners of the strips, the strips can be manufactured as a nested series with little void space between them.  Strips nest, in one embodiment, with the top edge of one strip adjacent the bottom edge of another strip or, in another embodiment, with the bottom edges of two strips adjacent to each other. Manufacturing economy is effected by forming, for example, by stamping, the rods in the nested condition.

Title: Narrow band excimer laser
Inventor: WAKABAYSHI OSAMU
IPC: H01S3/08
Filed: 1990-05-18
Abstract: A narrow-band oscillation excimer laser employing a diffraction grating as a wavelength selecting element, which is particularly suited for a light source of a reduction type projection aligner.  The grating used in the narrow-band oscillation excimer laser of the invention is so disposed that the direction of grating lines is nearly perpendicular to the direction of laser discharge. When a beam expander is used to expand laser beam falling on the beam expander is so disposed that the direction of beam expansion is nearly perpendicular to that of discharge of the laser. Further, when an aperture is to be used in the optical resonator, the aperture is placed so that the longitudinal direction may be parallel to the direction of laser discharge. Moreover, the front mirror of the optical resonator is a cylindrical one, whose mechanical axis is in parallel with the direction of laser discharge. This makes it possible to provide a narrow-band oscillation excimer laser having very high efficiency and excellent durability.

Filed: 1992-05-19
Abstract: ABSTRACT OF THE DISCLOSURE:            A device is described relating to separating mixed sub-stances of differing flowabilities, in particular for the purpose of processing foodstuffs.  The processing takes place in a device by which an elastic presser belt is pressed onto the periphery of a hollow separating drum with a perforated wall, so that the substance to be processed consisting of the previously mentioned composi-tion and located between the presser belt and the hollow separating drum is separated into a phase of easily and a phase of less easily flowable components.  The present concept provides for the use of two presser belt systems, which are operative one in series with and down-stream of the other and influence a hollow separating drum, thus offering  the possibility of using presser belts of different softness as well as, in the case of offset arrangement of the presser belt systems, use of varying perforations in the respectively associated cir-cumferential areas.
