Patent EP-0327731-A3 (EP)
Title: Plug-resistant arch-vent for a tire mold
IPC: B29K21/00
Filed: 1988-12-29
Abstract: A split tire mold having a tread ring in which provision is made for venting air circumferentially across the inner surface of the tread ring so that the air escapes from the parting line of the mold halves, dispenses with widely used, conventional, radially protruding vent stubs. The air is vented through "butterfly-shaped" or "double-wedge-shaped" arch-vents which provide passage for trapped air above each tread block of the tread as it is moved against the inner surface of the tread ring. The shape of the arch-vent passages and the angulation of the wedges is critical to the effectiveness of the arch-vent which forms an arch-vent bridge of cured rubber in a cured tire. The configuration of the bridge allows a cured tire to be easily removed from the mold cavity without leaving a broken-off piece of the rubber bridge to plug the arch-vents. This arch-vent design leaves unobtrusive flat-sided, narrow wedge-shaped pieces of rubber as the arch-vent stubs, tapered in two directions. The arch-vent stubs, when viewed in the radial direction towards the center of the tire, are so unobtrusive as to be cosmetically acceptable in a finished tire. The upper surface of the arch-vent is close to the inner surface of the tread ring and essentially horizontal, while the lower surface of each arch-vent is inclined at an angle in the range from 30 DEG -50 DEG  to the horizontal plane, but in opposite directions. An angle in this range provides surprising strength in the base area of the arch-vent stub so that, upon stripping the tire from the mold, the arch-vent bridge of cured rubber breaks cleanly and reliably at the narrowest and weakest point in the bridge.

Abstract: A method of measuring the yarn density of a woven 
fabric or the stitch density of a knitted fabric by record­
ing a video image of the woven or knitted fabric to be 
examined by means of a video camera, converting the video 
image by an analog-to-digital converter into digital video 
information, storing the digital video information in a 
digital image memory and converting said information by a 
central processing unit into the yarn density or stitch 
density. The digital video information is converted by a 
digital band filter (14) with central circle frequency (ω₀) 
into a yarn or stitch density, and that the digital band 
filter (14) is arranged in such a manner that it operates 
according to the formula:   
 
Y k = A n .X k-n +A n-1 .X k-n+1 .... ­
+ A₀X k -B₁.Y k-1 -B₂Y k-2 ...-B. n Y k     
 
wherein:  
Y k  represents a series of points of the digital information 
characteristic at interspace T before the digital filtering; 
Y k  represents the said series of points k of the filtered 
digital information characteristic via digital filtering at 
the same interspace T; the coefficients A and B are a func­
tion of the quality Q, the central circle frequency ω₀ and 
the interspace T.

Title: Plasma thin film deposition process control
IPC: C23C16/50
Filed: 1988-07-13
Abstract: In a process of depositing a thin film onto a surface of a substrate with the use of a plasma, wherein the plasma optical emission is monitored, analyzed, and the results used to automatically control the nature of the plasma in order to control the characteristics of the deposited thin film. One aspect of the emission that is detected is the intensity of each of two emission lines of different wavelength bands from the same plasma species, the intensities being ratioed and the ratio compared to a predetermined value known to provide a resulting film with uniform and repeatable characteristics. This ratio is also related to the average electron temperature of the plasma, which can be calculated from it. Additionally, the intensity of another emission line from another of the plasma species may be measured and ratioed to one of the foregoing line intensities if additional control is desired.

Title: Demodulator with composite transversal equalizer and eye detection clock synchronizer
IPC: H04L27/01
Filed: 1989-11-09
Abstract: In a digital demodulator, a recovered baseband signal is sampled in 
response to a clock pulse supplied from a VCO and converted to a digital 
signal representing one of multilevels of the sampled signal. Real-axis and 
imaginary-axis transversal equalizers are provided. Each equalizer has a 
tapped delay line for receiving the digital signal, a plurality of tap weight 
multipliers connected respectively to taps of the tapped delay line, and an 
adder. The adder of the real-axis transversal equalizer sums all outputs of 
the tap weight multipliers except for the output of one which is connected 
to a tap adjacent to the center tap for producing a partially equalized 
signal, while the adder of the other equalizer sums all outputs of the tap 
weight multipliers for producing a fully equalized signal. Both of the 
equalized signals are summed by an adder and applied to a phase control 
circuit which derives from it a VCO control signal so that it corresponds to 
a tap-weight control signal applied to the multiplier whose output is 
excluded from being summed by the adder of the real-axis transversal 
equalizer. The output of the adder is summed with the excluded multiplier 
output and supplied to a tap weight controller which controls the 
multipliers of both transversal equalizers.
