IPC: H03M7/30
Filed: 1987-12-11
Abstract: A data compression method and apparatus 
particularly suitable for use in electrical power 
line fault data recorders. The system performs both 
gain compression and frequency compression. For gain 
compression, a predetermined number of samples are 
analyzed to determine a gain setting common to each 
sample in the set of samples. A reduced data string 
consisting of a gain code and data words having fewer 
bits than the input words are transmitted as a 
compressed data string. For frequency compression, a 
sample set representing the input signal is decimated 
until there remain only a sufficient number of data 
samples to satisfy the Nyquist criterion for the 
highest frequency component of interest. The 
frequency compressed output data string comprises a 
frequency code representing the highest frequency of 
interest followed by the set of decimated data 
samples.

Title: Method and circuit concerning the resolution of digital signals
IPC: H04N19/60
Filed: 1988-08-20
Abstract: In digital signals transformed into a frequency domain, inaccuracies occur in the structure of the reproduced video signals due to rounding errors in the calculation of the coefficients with a shortened number of digits. 
<??>The invention provides a remedy in that the range of numbers of the direct component is transferred into the range of numbers of the alternating components and thus a greater range of numbers is available for the alternating components for the common processing of the direct and alternating components. 
<??>The invention can be used in digital systems with block-by-block processing in which a rounding of the spectral coefficients is carried out due to a limited number of bits in the calculation.

Patent EP-0294023-A3 (EP)
IPC: D02J13/00
Filed: 1988-04-18
Abstract: The present specification discloses an oven 
foruse in the orientation and heat setting of 
synthetic yearns and filaments. One known oven 
comprises an elongate chamber (1) through which a 
filament to be processed is passed, hot gas being 
introduced intot he chamber (1) near to the region 
where the filament enters the chamber. The hot gas 
is introduced into the chamber (1) under pressure in 
the general direction of filament travel and thus 
heats the filament as it passes through the chamber 
(1). However there is a problem as the hot gas 
quickly reduces in temperature due to the heat 
absorption by the filament and also due to the expansion 
of the gas as it enters the chamber (1). Thus very 
little heating is found to take place after the 
filament has passed through the jets of hot gas on 
entry into the chamber (1).  
     The present invention provides an oven comprising 
an elongate chamber (1) with an inlet orifice (5) at 
one end and an outlet orifice (7) at the other end, 
via which a filament can pass through the chamber (1). 
Primary nozzles (15) for use in introducing hot gas 
into the chamber (1) are arranged, together with a gas 
outlet port (13), adjacent to the said one end (5) 
of the chamber (1). Preferably the outlet port (13) 
is nearer to the said one end (5) than the primary 
nozzles (15). Secondary nozzles (17) also for introd­
ucing hot gas into the chamber (1) are arranged 
adjacent to the other end (7) of the chamber. In use, 
hot gas is fed under pressure into the chamber (1) 
via the primary and secondary nozzles (15,17) against 
the direction of filament travel. Whilst the hot gas 
 
 
is fed under high pressure through the primary nozzles 
(15), the hot gas is fed at a relatively low pressure 
but high volume through the secondary nozzles (17). 
In this way the filament is heated all along its 
length in the chamber (1).

IPC: H04N9/83
Filed: 1988-06-22
Abstract: A video signal reproducing apparatus has a filter circuit (31) interposed in a transmission path for a reproduced luminance signal, and the characteristic of the filter circuit (31) desirably includes a band-eliminating characteristic and a comb-filter passband characteristic which can be selectively emphasized. When the reproduced luminance signal has a normal or relatively smaller frequency bandwidth or a relatively small line correlation component, or when the level of the reproduced carrier chrominance signal is high, the band-eliminating characteristic of the filter circuit is emphasized. The foregoing video signal reproducing apparatus is particularly suited for reproducing a color video signal that includes a wide band luminance signal, in which case the comb-filter passband characteristic of the filter circuit is selected or emphasized so as to reduce noise near the color subcarrier frequency, to avoid displacement of a reproduced picture of high definition in the vertical direction and also to avoid interference caused by the vertical non-correlation component of a color picture.

IPC: G01R27/26
Filed: 1988-08-08
Abstract: A device and method for distinguishing between 
different fluids on the basis of their dielectric 
properties. In a preferred embodiment, the device 
comprises two substantially parallel conductive surfaces 
which are positioned on opposite sides of a fluid conduit 
so as to form a substantially parallel plate capacitor. 
The first conductive surface is electrically connected 
through an inductor to a voltage source, and such first 
conductive surface is also electrically connected to the 
source electrode of a field-effect transistor. A 
resonator device is electrically connected between the 
second conductive surface and the gate electrode of the 
field-effect transistor. The gate electrode of the field-­
effect transistor is further electrically connected 
through a fixed resistance to ground, and the drain 
electrode of the field-effect transistor is electrically 
connected directly to ground.  
     The inductance of the inductor is selected such that 
the resonant frequency of the inductor and the capacitor 
is substantially the same as the operating frequency of 
the resonator device when a desired column of fluid is 
 
 
positioned between the two conductive surfaces. In this 
state, the output voltage of the detector device will 
oscillate. However, when a column of fluid having 
significantly different dielectric properties is 
positioned between the two conductive surfaces, the 
resonant frequency of the inductor and the capacitor will 
change, and the output voltage of the detector device 
will stop oscillating.

Title: Variable rate coder
IPC: H04B14/04
Filed: 1989-09-26
Abstract: A variable rate coder for transforming an input 
signal into a low bit rate digital signal, comprising: a 
plurality of coding units (111, 121, 131) each 
comprising an output quantizer having a different 
number of output bits, and each independently 
transforming the input signal into a compressed digital 
signal. A plurality of bit rate determining circuits 
(24, 3a) are provided to determine an output of one of 
the plurality of coding units (111, 121, 131) as an 
output of the coder by an individual determining method, 
in which method, quality of a signal which is 
regenerated from an output of each coding unit is 
compared with an individual predetermined quality 
evaluating standard, and then an output of a coding unit 
having a smallest number of output bits among outputs of 
coding units satisfying each standard, is determined as 
the output of the coder. One output among the plurality 
of the above determined outputs, which is determined by 
a most suitable determining method for the level of the 
input signal, is used to select the output of the coder 
(Fig. 1). Further, when the number of the output in each 
of the coding untis (111, 121, 131) can be variably set, 
the most suitable number of output bits for the output 
of the coder is calculated based on prediction gains of 
the coding units (111, 121, 131), a required signal-to-noise 
ratio of the coder, and an ADC signal-to-noise 
ratio at the analog to digital converter, and the number 
of the output in each of the coding units (111, 121, 
131) is set based on the above calculated value, before 
the above operation by the bit rate determining circuits 
(24, 3a).
