Title: Method and apparatus for determining parameters of gaseous substances
Inventor: UNEUS LEIF
IPC: G01N21/25
Filed: 1987-02-05
Granted: 1991-04-30
Abstract: ABSTRACT      A method for determining parameters, especial-ly pressure, temperature, concentration, number of particles and particle size distribution, of gaseous substances present in combustion processes and other high temperature processes, comprises transmitting spectrally broad-band light through an object (2) of measurement, spectrally dividing the light trans-mitted through said object, and recording the spectral distribution of the light in the studied wavelength range a large number of times. Each recording occurs sequentially in that the spectrally divided light is swept relative to a one-channel detector and for such a short time that the total light intensity of the entire wavelength range is constant during each recording. After that, the mean value of said recorded spectral distributions is generated, and the required parameters are calculated on the basis of said mean value spectral distribution, the appearance of said mean value spectral distribution, as well as spectra calculated or recorded for known conditions, being utilised for said calculation.     An apparatus comprises means for carrying out the method.     Fig. 1

Title: Digital phase locked loop stabilization circuitry
Inventor: DEMMER WALTER H
IPC: H04N11/04
Filed: 1987-03-27
Granted: 1992-07-28
Abstract: RCA 82,993 Abstract of the Disclosure A digital television receiver includes a first phase locked loop which develops a sampling clock signal that is locked to the horizontal line synchronizing signals components of a composite video signal.  A second digital phase locked loop is clocked by the sampling clock signal and develops a digital signal that is phase locked to the color burst signal.  This signal is used as a regenerated color subcarrier signal to synchronously demodulate the chrominance components of the composite video signal into and Q color difference signals.  To compensate for frequency instabilities in the regenerated subcarrier signal caused by frequency instabilities in the line-locked clock signal, a third digital phase locked loop develops an oscillatory signal which is phase locked to a reference signal generated by a crystal controlled oscillator. Control signals from the third phase locked loop are applied to circuitry which develops control signal that is independent of the crystal frequency.  This control signal is applied to the second phase locked loop to substantially compensate for frequency instabilities related to the clock signal. Since the control signal applied to the second phase locked loop is independent of the frequency of the control, there is no need for manual adjustment of the crystal oscillator.

Abstract: ABSTRACT OF THE DISCLOSURE         Paint spray guns are cleaned in respective cleaning tanks.  In each of the cleaning tanks, a cleaning fluid is ejected to the nozzle end of the paint spray gun by a plurality of cleaning guns disposed in the cleaning tank.  The paint spray guns and the cleaning tanks are relatively movable so that the cleaning tanks are retracted away when the paint spray guns spray a paint coat over a desired object such as a vehicle body.  Each of the cleaning tanks includes two flexible cover members having holes for inserting the paint spray gun therethrough.  The cover members and the inserted paint spray gun close a cleaning chamber defined in the cleaning tank to prevent the cleaning fluid from leaking out.  Each cleaning tank comprises a base plate and a casing detachably mounted on the base plate and defining the cleaning chamber.  Nozzles or an annular pipe is mounted on and outside of each cleaning tank for ejecting air under pressure to the paint spray gun which has been displaced out of the cleaning tank, thereby to dry any remaining cleaning solution on the paint spray gun.  Pipes for supplying paint to the paint spray guns are also cleaned by air under pressure and a solvent which are introduced into the pipes to produce air bubbles for removing paint deposits from within the pipes.

Title: Process and apparatus for testing the airtightness of a hollow body
Inventor: LEHMANN MARTIN
IPC: G01F17/00
Filed: 1987-11-10
Granted: 1995-05-16
Abstract: The invention relates to a process and apparatus for testing the airtightness of a closed container.  The closed container is placed in a test chamber and a pre-chamber is brought to a desired pressure and then connected with the test chamber.  The pressure in the test chamber is stored at a certain point in time on the input side of a differ-ential pressure sensor and then the course of the test chamber pressure is compared with the reference pressure thus formed.  Any pressure compensation, which occurs if leaks are present in the hollow body, is recorded as an indication of such leakage.  The process allows the air tightness of closed containers to be tested in a simple, reliable and non-destructive manner.

Abstract: ABSTRACT    An internal, self-locking hub assembly for a compact, audio, tape cassette is described including a locking member with two movable portions and a spring.  The tape cassette includes receptacles formed in a raised annular ring thereof.          The spring normally forces the two movable portions radially inward in a direction parallel to the plane of the hub, wherein the two movable portions engage the receptacles in the raised annular ring, and lock the hub against rotation.  on the other hand, when the tape cassette is placed into a tape player/ recorder, the spindle thereof enters the center of the hub, abuts and moves the two movable portions radially outward against the force of the spring thereby unlocking the two movable portions from the receptacles and permitting normal rotation of the hub.  A related method includes the steps of: forming the locking member to include two movable portions, a spring and a locating member; picking up the locking member; forming a hub to include a mounting member corresponding to the locating member; advancing the locking member to the hub; inserting the locking member into the hub such that the locating member is fixedly received by the mounting member; mounting the hub into a cassette base; forming a cassette cover to include the receptacles; and positioning the cassette cover on the base, such that the receptacles receive the two movable portions.

Abstract: Abstract of the Disclosure Pivot Assembly A pivot assembly provides limited pivotal motion between a relatively stationary member and a relatively moveable member which is supported on the stationary member.  The stationary member is secured to a vehicle frame and the moveable member forms a portion of an endless track supporting frame.  The pivot assembly includes a plurality of elastomeric bearings between the stationary and moveable members and a loading member to compress and preload the bearings.  Conventional pivot assemblies utilize metal sleeve, roller or ball bearings to provide relative pivotal motion between stationary and cooperative moveable members.  Such metal bearings require constant lubrication, and seals to contain the lubrication, and produce objectionable noise and vibration.  The subject pivot assembly requires no lubrication or seals and generates low levels of noise and vibration by isolating the stationary and moveable members with the elastomeric bearings.  The dual tapered, elastomeric preloaded bearings restrain and capture the relatively moveable member axially and radially without a thrust bearing.
