Patent EP-0214741-A3 (EP)
IPC: B08B1/02
Filed: 1986-07-29
Abstract: Apparatus for treating sheet articles (4), to remove in an 
automatic and efficient manner from the surfaces (14, 24) of 
sheet articles (4), such as photographic films, deposits and 
other impurities marring the optical properties. The apparatus 
has two pairs of transfer rollers (10, 11 and 20, 21) in contact 
with the respective surfaces (14, 24) of the said sheet article (4) 
and cleaning rollers (12, 22) in contact with a respective pair of 
transfer rollers (10, 11 and 20, 21). The tackiness of the sur­
faces of the cleaning rollers (12, 22) is greater than the tack­
iness of the surfaces of the transfer rollers (10, 11, 20, 21) such 
that impurities are lifted from the surfaces of the article (4) and 
transferred to rolls of adhesive film wound round the cleaning 
rollers (12, 22). A release mechanism (28) is provided to re­
move the rollers (12, 22) for renewal of the film.

Title: Device for registering roadway condition data
IPC: G08B19/02
Filed: 1987-02-21
Abstract: This device has electrodes for measuring the electric surface conductivity. Since the conductance of a roadway pavement does not yet provide adequate information on the condition of the roadway, additional means are provided for detecting at least one of the additional criteria  a) the degree of coverage of the roadway by moisture or by ice,  b) the water level or the thickness of the ice,  c) the presence or concentration of salt. For the detection, a box is preferably provided which can be recessed in a roadway and in the exchangeable lid of which various electrodes are arranged at the top. <IMAGE>

Title: Method and apparatus for producing a curved image on a graphics display device
IPC: G06T11/00
Filed: 1987-04-10
Abstract: A method and apparatus of providing a visual representation of a curve image wherein curve image data is provided by a B-Spline equation computed with a forward difference technique using scaled integer variables. The method provides for the scaling of the initial base matrix computation of the geometry vector coefficients followed by the computation of the forward difference interval coefficients using integer arithmetic. The curve coordinate values for each interval are computed from the forward difference interval coefficient integers descaled by the scaling parameter. By employing integer arithmetic in a divide approximation technique, the use of floating point arithmetic is avoided. The apparatus for producing the visual representation of the curve image includes a computational section that provides for pipelined computations of the forward difference interval coefficients to provide high-speed curve coordinate value computation.

IPC: C08L67/00
Filed: 1987-02-03
Abstract: Compositions comprising polyester or polycarbonate 
having reacted therein a total of from about 1.0 to about 5,000 
parts by weight per million parts by weight of polyester of at 
least one UV absorbing compound of the formula 
  
wherein R is alkyl or the like, X is carbonyl or sulfonyl, R¹ is 
hydrogen or a substituent, and Y and Z are hydrogen or sub­
stituents such as cyano or alkoxycarbonyl, with the provision 
that at least one of R, R′, Y, and Z is, or forms part of, or 
contains one or more reactive groups capable of undergoing 
a condensation reaction under polyester forming conditions, 
such that the UV absorbing compound is reacted into the 
polymer. The compound has a maximum light absorbance 
within the range of from about 320 nm to about 380 nm, 
which is nonextractable from the polyester and stable under 
the polyester processing conditions, for imparting UV 
screening properties to the polymer. Many products such as 
fruit juices, sort drinks, wines, food products. cosmetics and 
shampoos are deleteriously affected by UV light when pack­
aged in clear plastic containers which pass significant port­
ions of the available light at any wavelength from app­
roximately 250 to 390 nm. By use of the present compounds 
polymeric containers can be manufactured which absorb 
these harmful wavelengths and therefore reduce or eliminate 
the UV light degradation of products packaged therein. A 
further advantage of the present polymeric compositions is 
that conventional polyester dyes and other additives such as 
pigments, fillers, brighteners and the like may be incorpora­
ted therein, and the UV screening properties of the methine 
compounds impart significant stabilization to both the poly­
ester and the dyes.

Title: Gate array oscillator with noise rejection
IPC: H03K3/0231
Filed: 1988-06-21
Abstract: An oscillator with noise rejection formed in a gate array in 
a semiconductor chip comprising first amplifier means (14, 16, 18), means 
for connecting an external feedback element (15) across the input 
and inverting output of the first amplifier means for 
generating and amplifying the a sine wave, and means (20, 22) 
connected to the inverting output of the first amplifier 
means for generating a square wave with the duty cycle 
thereof being proportional to the difference between the 
center of the voltage swing of the amplified sine wave and a 
reference voltage.  
     In a preferred embodiment, the first amplifier means and the 
generating means each include a current 
switch (16, 18; 20, 22). A voltage 
reference network (70, 72) is provided to set the reference voltage 
for the current switch in the generating means to the center 
of the voltage swing of the sine wave applied to that 
current switch. This results in a 50% duty cycle square 
wave for the output signal. A current source voltage 
reference is included for ensuring that each of the current 
switches and the voltage reference network drive 
approximately constant equal currents.
