Filed: 1990-09-27
Abstract: Abstract of the Disclosure A system for purification of refrigerant within a storage  container  includes  a  filter/dryer  for  removing contaminants' from refrigerant passing therethrough,  and a refrigerant pump connected to the storage container to circulate refrigerant in a closed path from the container through the filter/dryer and return the refrigerant to the container.  The system configuration is such that the refrigerant is in liquid phase in at least a portion of the closed path.  A pressure-differential valve has an inlet coupled to a purge port on the container for receiving air captured within the container.          Container air pressure at the valve inlet is fed to one side of a flexible diaphragm.  Circulating liquid refrigerant is passed in heat transfer contact with a sealed enclosure containing liquid refrigerant, so that the refrigerant within the enclosure is at saturation pressure and acts on the opposing side of the diaphragm in conjunction with a valve spring.  The diaphragm is coupled to a valve element that lifts from a valve seat to connect the valve inlet to an outlet, and thereby vent air from within the storage container, whenever container air pressure exceeds refrigerant saturation pressure by a threshold that is determined in part by the valve spring.

Title: Device in connection with an inhaler
Inventor: ANDERSSON JAN A R
IPC: A61M13/00
Filed: 1990-03-02
Abstract: The present invention refers to a device in connection with an in-haler intended for measuring and recording the course of inhalation of a patient. The device is intended for use in medication, e.g. in clinical tests, where there is a need of afterwards being able to control if the patient has taken medicine in a prescribed way. The device comprises an electronical unit provided in the inhaler for recording of the time for each dosage of the medicine of the inhaler. A detector (16, 32, 36) is provided in the inhaler in connection with a passage for the airflow of the inhalation, whereby the detector detects the airflow of the inhalation through the inhaler as well as the availability of the medecine at the inhalation, so that a combination of these two detected values decides if and how the performed inhalation should be recorded in the electronical unit (11, 33, 35).

Title: Means for cleaning doctor device for spreader
Inventor: SOLLINGER HANS-PETER
IPC: B05C11/04
Filed: 1990-12-06
Abstract: ABSTRACT           In order to clean the support region at the bottom end of a doctor element which is clamped to a support and is thereby held to the surface of spreadable material to be doctored, the leaf spring doctor element is removable from a stop on the support against which the leaf spring is clamped in operation by a plate pusher.  The support is shaped to have a groove extending along the width of the stop and the support for the doctor element.  A sidewall of the groove is defined in a ledge that is movable along the support and along the groove.  The sidewall supports oscillation pulse transmitters.  A liquid pulse transmitting medium in the groove transmits the oscillations across the groove to the area of the leaf spring support to be cleaned.  The oscillation pulse transmitters may be a series of transmitters extending along the sidewall along the groove or may comprise a long bar-shaped oscillator which is oscillated at its ends.  Bearing pedestals at spaced intervals corresponding to the oscillation nodes may support the bar-shaped oscillator.

Inventor: KALTURNYK BILL
IPC: G10H1/32
Filed: 1990-12-07
Abstract: ABSTRACT           In the use of some of the modern musical amplifiers, it is possible to blend the sounds from two separate channels.  This invention is a foot pedal equipped with a "panning potentiometer" to provide remote control, infinite degrees of mixing of the sounds, and the possibility of mixing sounds between two amplifiers.  The advantage of this invention, aside from giving all amplifiers the capability of channel mixing, is that from a remote position the user can acquire an infinite number of mixtures and be assured that the volume of sound will never exceed the preset limits.  The mix can be changed during performance and the necessity of making time consuming adjustments at the amplifier is eliminated.

Inventor: BERNER ERLING
IPC: F24F3/14
Filed: 1991-05-13
Abstract: An apparatus and method for dehumidifying air includes a duct with at least four ports, two at each end. The ports are regulated by valves that are biased in the closed position. A desiccant containing matrix is disposed within the duct. One or more fans are adapted to produce substantially axial air flow in two directions through the duct: a first direction during a regeneration phase of the dehumidifying cycle and a second direction during a process phase of the dehumidifying cycle. In the process direction, air from the enclosure enters one end of the duct, passes through the desiccant containing matrix where moisture is absorbed by the matrix and exits through the opposite end of the duct back to the enclosure. The air is thus at a lower relative humidity when it leaves the apparatus. Upon reversal of the air flow direction, the air is drawn into the duct from a source outside the enclosure, heated by a heater, passed through the desiccant containing matrix where moisture is absorbed from the matrix and exits through the opposite duct back into the source of air. The air is thus at a higher relative humidity when it is exhausted from the apparatus.

Title: Apparatus and method for cooling rotating blades in a gas turbine
Inventor: NORTH WILLIAM E
IPC: F02C7/18
Filed: 1991-09-03
Abstract: 56,074 ABSTRACT OF THE DISCLOSURE An apparatus and method are provided for cooling the rotating blades in the turbine section of a gas turbine.  Cooling of the leading edge is accomplished by forming a radial passageway in the leading edge portion of the blade airfoil.  Rows of holes along the leading edge of the blade airfoil allow cooling air to flow from the radial passageway to the surface of the leading edge, thereby cooling the leading edge portion of the airfoil.  The flow area of the radial passageway reduces as it extends radially outward so that the velocity of the cooling air flowing through the passageway is maintained.  A plenum formed in the root portion of the blade distributes cooling air to small diameter holes in the center and trailing edge portion of the airfoil.

Title: Process for the preparation of photographic color copies
Inventor: KRAFT WALTER
IPC: G03B27/73
Filed: 1991-09-06
Abstract: In a photographic copy process the copy master is scanned in intervals, by a source of measuring light. The measuring light is spectrally split, detected and converted into electrical measuring signals. The n spectral measuring signals are converted into n spectral density values, compared with neutral densities and n spectral density differences formed.      In a data compression the n spectral density differences are converted by an orthogonal transformation to m < n transformation coefficients. The transformation coefficients are analyzed in a color and density correction routine and deviations computed. From the deviations the copy light quantities and exposure corrections adjusted to the copy material are determined. The photographic copies are produced by the exposure values determined.
