Patent NO-175798-B (NO)
Inventor: KROKSTAD ASBJOERN
IPC: G10K11/178
Filed: 1992-07-22
Abstract: PCT No. PCT/NO93/00114 Sec. 371 Date Mar. 21, 1995 Sec. 102(e) Date Mar. 21, 1995 PCT Filed Jul. 9, 1993 PCT Pub. No. WO94/02935 PCT Pub. Date Feb. 3, 1994A method for active noise reduction based on destructive interference of sound waves in order to reduce the energy in a sound field employs two omnidirectional microphones (M1, M2) provided in connection with a loudspeaker. The acoustic feedback of the microphones is eliminated by a closed loop consisting of the microphones and the loudspeaker. The loudspeaker used is an open loudspeaker with a dipole characteristic, thus causing one of the microphones to be more sensitive to the far field and thereby to the noise which has to be suppressed. The method is implemented by a device which comprises a digital signal processor (DSP) for processing the microphone signals and which transmits an output signal to the loudspeaker where the feedback component from the loudspeaker is substantially eliminated, while the output signal's phase and amplitude are adjusted in such a manner that an effective cancellation of the noise is obtained in an area around the loudspeaker's near field. The DSP can preferably be implemented in the form of software modules on an integrated circuit. With the method and the device an integrated reduction in noise level of almost 20 dB is achieved depending on how the filtering in the DSP is adapted. In practice a quiet zone can be obtained in the loudspeaker's near field with an attenuation band which extends from approximately 100-500 Hz.
Patent SE-311314-B (SE)
Inventor: LANE M
IPC: C04B28/14
Filed: 1965-03-26
Abstract: Cast gypsum articles are produced by a twostage process in which the calcined gypsum is first mechanically disposed in water at an intensity and for a time sufficient to increase the surface area of the unhydrated calcined gypsum in the slurry, and then an accelerator is added and the slurry is cast while the gypsum is still substantially unhydrated.  The amount of accelerator must be sufficient to produce a temperature rise set in not more than 15 min.; this is usually 0.1-1.25% by weight of the calcined gypsum. Suitable accelerators are potassium, aluminium, zinc or ammonium sulphates, or gypsum dihydrate, e.g. as land plaster or freshly ground cast gypsum block.  Preferably the calcined gypsum is dispersed to a surface area of at least 12,000 cm.2/g., and has a combined moisture content prior to casting less than 9% by weight.  A keratinaceous retarder, usually in an amount 0.0025-0.015% of the gypsum, may be present in the first dispersion stage; so also may reinforcing materials such as cellulose, synthetic plastic and glass fibres, binders such as flour or starch, and dispersing agents such as ammonium lignosulphonate. A lightweight cellular gypsum is formed by the incorporation of a premixed foam after the dispersion step, preferably in a period of less intense mixing in which the accelerator is also added.  Gypsum board may thus be produced with a density of 35-50 lbs./cu. ft.

Abstract: 1332370 X-ray spectrometer MEDINOVA A B 14 May 1971[21 May 1970] 15124/71 Heading G1A [Also in Division H5] An X-ray spectrometer for measuring more than one constituent in a sample comprises an X-ray tube supplied with a high voltage cyclically varying between two levels to provide emission at two different, alternating wavelengths and a filter system arranged to switch in filters in synchronism with the high voltage variation to define more accurately the separate wavelengths. The apparatus of Fig. 1 is suitable for the determination of bone salts and soft parts in a part of the body 5 which may be inserted in the measuring beam. The tube 2 is supplied with a high voltage comprising a pulsating component superposed on a substantially constant D. C. level via transformers and smoothing circuits etc. 1. The tube has a water cooled tungsten target which omits X-ray radiation at an energy proportional to the applied voltage. The emission from the tube is arranged to provide a measuring beam towards detector 6 and a reference beam for compensating for fluctuations in X-ray source intensity to detector 6a. In the path of both beams is the filter system comprising a rotary sector disc having two opposite sectors of thorium and two of samarium. The rotation of the disc is monitored by electrooptical arrangement 3 and is arranged to synchronize the thorium filter with the high voltage part and the samarium with the low constant part of the X-ray supply waveform. In operation, without the test body 5 in position, the positions of wedges 4a, 4b of simulated bone salts and soft tissue, respectively are adjusted to equalize the intensities of the two different alternate energies in the measuring beam, and also to equalize them with the intensity in the reference beam. Bone salts absorbers 7, 4e and soft tissue absorbers 7a, 4f are provided to aid thus calibration. On insertion of the test body, the output of detector 6 changes for both energies. The detector output corresponding to bone is channelled by gating circuits 8 to a first differencing circuit (with the corresponding reference channel signal) and that corresponding to soft tissue to a second differencing circuit, Fig.3 (not shown). The signals comprise pulses which are rendered all of equal amplitude, the pulse rates being representative of intensity (effectively the number of pulses detected during each half cycle). These digital differences are converted by D/A converters to supply motors 4c, 4d to drive the wedges 4a, 4b to balance the intensities once more. The necessary displacements of respective wedges represent the amounts of the respective constituents.

Title: Spectral shift reactor
Inventor: CARLSON WILLIAM RALPH
IPC: B23K26/14
Filed: 1981-12-03
Abstract: A spectral shift pressurized water reactor comprising apparatus (38) for inserting and withdrawing water displacer elements (40, 82) having differing neutron absorbing capabilities for selectively changing the watermoderator volume in the core (34) thereby changing the reactivity of the core. The displacer elements (40, 82) comprise substantially hollow cylindrical low neutron absorbing rods (40) and substantially hollow cylindrical- thick walled stainless rods (82). Since the stainless steel displacer rods have greater neutron absorbing capability, they can effect greater reactivity change per rod. However, by arranging fewer stainless steel displacer rods (82) in a cluster, the reactivity worth of the stainless steel displacer rod cluster can be less than a low neutron absorbing displacer rod cluster.

Abstract: A beacon is placed at a specific location, such as a bus stop and has a local communicator which transmits a code to a mobile telephone. The code identifies a predetermined item of information stored on a remote server, such as a bus timetable document. This information is retrieved by the mobile telephone using its network communicator. The mobile telephone then transmits a copy of the information to the beacon which stores it in its cache and also displays the document to its user. A PDA, which lacks a network communicator, is then able to retrieve the cached information directly from the beacon using only its local communicator. The PDA then displays the bus timetable document to its user.
