Patent EP-0252377-A3 (EP)
IPC: G01V1/133
Filed: 1987-06-25
Abstract: A water gun seismic source for use in 
underwater environments has a sleeve valve (100) for 
opening a jet aperture (37, 101) to enable jets of 
pressurized water to be emitted for the generation of a 
seismic signal. The water is pressurized by a drive 
piston (3) which is reciprocated to a cocked position 
for pressurizing the water for the jets. A compressed 
air operated cocking mechanism (4, 7, 8, 76 or 110-199 
or 200-260) is coupled to the piston for cocking it. 
The cocking mechanism may utilize a cocking piston (7) 
slideable on a shaft (7) connected to the drive piston 
(3) which cocking piston is returned to a position where 
any load due to such cocking piston is decoupled from 
the shaft. The sleeve valve (100) may be biased to 
close the jet aperture ports (101) by compressed air and 
opened with high timing resolution when the pressurized 
water held back by the sleeve valve is applied to 
actuate it (via 40, 41, 50 & 43). Compressed air may be 
released in the vicinity of the jet aperture ports to be 
entrained with the jets and assist in forming the vapor 
cavities which collapse to produce the seismic signal. 
When compressed air is used to help nucleate the vapor 
cavities it may also be applied, instead of the 
pressurized water, to the seat of the sleeve valve to 
actuate the sleeve valve and open the jet aperture ports.

Title: Slag detector apparatus for molten steel process control
IPC: G01N33/20
Filed: 1988-08-29
Abstract: A slag detector apparatus (28) is capable of 
detecting a condition of 5% or less slag (L) entrainment in 
a molten metal stream (S) so that actions can then be taken 
to shut off further discharge of the molten metal (M) from 
the ladle 12 to the tundish (14) in a continuous casting 
line (10). The molten metal stream (S) has a fluctuating 
cross-sectional dimension and is composed of a continuous 
succession of recurring cyclical globules (G) of molten 
metal. The slag detector apparatus (28) employs a coil 
(32) having an axial length at least equal to the length 
(1) of each globule (G) of molten metal in the stream (S) 
thereof. The impedance of the stream (S) due to entrain­
ment of slag (L) therein is reflected in the terminal 
impedance of the coil (32). An impedance detector (40) is 
employed for periodic sampling and smoothing of the fluctu­
ations of the terminal impedance of the detector coil (32).

Abstract: A corrugated paperboard, manufactured with a layer of 
plastic film approximately 1-3 mil thickness, is laminated 
to the single face liner of single face board in the double-­
backer. The board has good moisture vapor transmission 
(MVT) properties for packaging food and chemical products. 
The film is supplied in roll form and reeved over a 
dewrinkling roll device to smooth it, then fed onto the 
single face liner as the single face corrugated is fed into 
the nip of the double-backer. The lamination of the film is 
made by the residual heat from the paper and pressure of the 
double-backer belt in the drying section of the corrugator 
without adding adhesives or other compounds. The film is a 
thermoplastic co-extruded polymeric film, e.g. high density 
polyethylene (HDPE), polypropylene, PET, having a heat seal 
layer thereon of a copolymer of olefin with Alpha-Beta 
monoethylenically unsaturated monomer, e.g., ethylene 
acrylic acid (EAA). The film surface of the manufactured 
board may be optionally treated with Corona discharge or 
high velocity flame treatment to oxidize the surface to 
enhance adhesive bonding in later prepared cartons made from 
the board. The process is applicable to single wall or 
multiwall corrugated paperboard in making a vapor barrier 
product having good MVTR.

Title: Forward looking windshear detection apparatus and method
IPC: G01P5/10
Filed: 1989-09-01
Abstract: An integrated, remote sensing and reactive 
detection system is provided for detecting and 
confirming the presence of hazardous microbursts, 
macrobursts, and windshears in the general flight 
path of an aircraft. An infrared remote sensing 
system is used to seek out, detect, and provide 
advanced alerts of thermal gradients ahead of an 
aircraft which correlate with windshear conditions. 
The measurement of atmospheric temperature is 
accomplished by a scanning, multi-spectral radiometer 
that sweeps an approximate 60 degrees path in front 
of the aircraft at about a 5 hertz rate. The 
radiometer employs two rows of detectors that are 
slightly offset resulting in two simultaneous 
measurements of temperature that are about 7 degrees 
apart in elevation angle. This dual information 
allows the continuous measurement of the atmospheric 
vertical temperature gradient, or lapse rate, for use 
in determining the atmospheric stability, and hence 
the probability of microburst occurrence as well as 
the continuous measurement of atmospheric azimuth 
temperature gradient for use in detecting the 
existence of a negative gradient that correlates with 
a microburst.

Title: Audio loading modulated side pincushion correction circuit
IPC: H04N3/23
Filed: 1990-02-15
Abstract: The power demand of a dynamic audio load 
(22) is monitored, for example, by sensing the voltage 
level of the power supplying the audio load (22). An audio 
load control signal (V al ) corresponding to the power demand 
is generated. The audio load control signal (V al ) is 
advantageously applied to a circuit (30) for producing a 
side pincushion correction current (i m ), for modulating the 
side pincushion correction current by the audio load 
demand. The audio load modulated side pincushion 
correction current (i m ) is used to modulate a horizontal 
deflection current (i Y ) in order to compensate for both 
side pincushion distortion and dynamic audio load induced 
raster width distortion. A filter network (R3,C5) may also 
be provided for removing high frequency signal components 
from the audio load control signal (V al ).
