Title: Low noise refrigerator
Inventor: NAKANISHI KEIJI
IPC: G10K11/178
Filed: 1990-12-18
Abstract: In a refrigerator system wherein compressor noise is counteracted by interfering sound from a generator, the noise is detected by a vibration sensor on the compressor thus excluding the feedback effects experienced when a microphone is used. The refrigerator includes; a rotary compressor (120) for compressing a refrigerant; a machine chamber (110) for accommodating said rotary compressor, and having an opening (117) at one location, the machine chamber having a one-dimensional duct construction in which a cross-sectional dimension of the duct is small relative to the wavelength of the compressor noise to be reduced; a vibration pick-up (130) for detecting compressor vibrations in the tangential direction of the rotary compressor, the compressor vibrations being representative of said compressor noise and the vibration pick-up being located in the vicinity of said rotary compressor; a control circuit (140) for processing an output signal of the vibration pick-up; and a sound generator (150) for generating a control sound corresponding to said compressor noise, wherein the sound generator is driven by an output signal from said control circuit, and the generated sound reduces the audible noise from the rotary compressor. The pick-up may be mounted on a circumferential surface of the compressor or on an end plate thereof. <IMAGE>

Title: Beverage package with enlargeable headspace
Inventor: LYNCH FRANCIS JOSEPH
IPC: B65D85/73
Filed: 1992-06-30
Abstract: A beverage package and a method of packaging a beverage such as beer containing gas in solution has a container can 1 having a primary chamber 1A charged with beer 14 to form a small headspace 15. The can 1 is sealed and includes a submerged insert 8 forming a relief chamber 6 which is sealed by a closure 11. The insert 8 is responsive to heat applied during pasteurisation which causes the closure 11 to open the relief chamber so that the latter can accommodate beer derived from the primary chamber 1A to provide an enlarged headspace 15A. The small headspace 15 initially provided facilitates removal of air therefrom prior to sealing of the container while the enlarged headspace 15A is adequate to accommodate froth or foam developed by the intentional liberation of gas from solution in the beer. An insert part 7 forming a secondary chamber 5 may be provided for injecting gas or liquid into the beer to liberate gas therefrom for froth or foam development in the enlarged headspace. The relief chamber 6 may contain gas under pressure so that when opened to the primary chamber the release of such gas pressurises the enlarged headspace 15A. The insert part 7 may be located within the relief chamber 6. <IMAGE>

Title: Oscilloscope display enhancement technique
Inventor: LECKLIDER THOMAS H
IPC: G01R13/34
Filed: 1992-09-21
Abstract: When an oscilloscope display is time-base-compressed detail is lost in the displayed waveform. To overcome this the enhancement technique comprises modulating display pixel brightness in accordance with the number of data samples compressed onto each display pixel. Thus highly detailed segments of the compressed waveform are increased in brightness. An analog input waveform 50' is sampled to give data samples D1 - D10. Local MAX and MIN values are determined and a vertical bar 50'' is displayed with its brightness modulated according to the local density of data samples. The bar is brighter where local MAX and MIN ranges overlap (see fig 6). <IMAGE>

Title: Sonic measurement while drilling.
Inventor: SCHERBATSKOY SERGE A
IPC: G01V1/52
Filed: 1993-03-29
Abstract: A sonic logging arrangement using a measuring while drilling telemetry system in which a fluid pump (27, Fig. 2 not shown) circulates drilling fluid through a drill string and produces a high differential pressure between the inside 18a and the outside 23 of the string. A portion of the fluid is bypassed, via a valve 1, from the inside 18a to the outside 23 of the string, thereby producing acoustic pressure waves in the formations 30 surrounding the borehole. Transducers 6, 7 are provided for receiving these acoustic pressure waves from the formation 30 and produce a signal which is processed and telemetered to the surface using the measuring while drilling system. <IMAGE>

Title: Method for adjusting the altitude given by an altimeter on board an aircraft
Inventor: MARTIN LAURENT
IPC: G01C5/00
Filed: 1994-09-26
Abstract: An aircraft 1, Fig 1, overflying terrain with vertical relief 2 has an altimeter to give its height Za with respect to a reference (sea) level, means such as a radiosonde to measure height Ha above the terrain, and a stored digital 3D map of the terrain including relief heights Zs. The map is divided horizontally into grid areas 21, Fig. 3, and the aircraft trajectory 22 is divided into segments 23-29 based on the grid. For each segment, heights Ha are subtracted from altimeter height readings Za to give a sequence of calculated relief heights Zc. The standard deviation Ec of the latter is compared with a reference value Es for the grid area to get a difference DE; if DE falls below a threshold value SE, then Ec and Es are judged compatible and the mean altitude ZOc of the calculated relief heights Zc is subtracted from a mean reference altitude ZOs for the area to get a value DZ which is used to correct the altitude reading Za. <IMAGE>

Title: Insulation of component leads
Inventor: WING JEAN MAURICE
IPC: H05K1/02
Filed: 1995-03-30
Abstract: A member of conductive material, such as a heat sink (10), defines apertures (14) through which the pins of electronic components extend into a printed circuit board. The apertures (14) are insulated by a method including the insertion of a strip (32) of insulating material (such as a prepreg) and the heat sink (10) between a pair of platens so that insulating material is pressed into the apertures (14). The resultant heat sink is improved in that the production process is simplified and made more reliable, and the resultant insulation sleeves (33) are located more strongly against axial displacement as they are additionally secured to a face of the heat sink by the adhesion of the strip (32) which can also be reinforced by an internal filamentous substrate.
