Patent EP-0291568-A2 (EP)
Inventor: FERRARA GIUSEPPE
IPC: B29C73/10
Filed: 1987-09-28
Abstract: The method according to the invention allows the production of patch-rubbers intended to repair radial-ply and bias-­ply tires. 
     Said patch-rubbers, while showing the same strength as the nowadays known, are more flexible and do not affect the original mechanical features and performances of the regions of the tires having been repaired therewith. 
     The patch-rubbers obtained by implementing the method are also suitable to perform retreading operations on tires by means of both high pressure molding machines and autoclaves. 
     The method essentially consists in inclining, in respect of the longitudinal or symmetry axes of the patch-rubbers, alternatively in the clockwise and in the counterclockwise direction, the cords made of a fibre and embedded into each one ply of a plurality of superposed plies, and in superposing to said plies, having said cords made of a fibre embedded therein, a further ply of smaller area having rectilinear metallic or fibre cords embedded therein; said further ply being so positioned that, when the patch-rubber is applied to the tire to be repaired, said metallic or fibre cords either match the direction of the radial metallic cords forming the casing of radial-­ply tires in the sidewalls and in the tread respectively, or form a given angle with the direction of the biased metallic cords forming the casing of bias-ply tires.

Abstract: To reduce the noise signals of a video signal generated at the output (16) of a video head amplifier (3), the frequency response of a video replay head (1) preceding the video head amplifier is lifted by means of the parallel connection of a suitably dimensioned capacitor (10) by a resonant point in the area of the upper frequency limit of the frequency band reproducing the luminance of the video signal and the frequency response of the video head amplifier (3) is lowered in the same frequency band in such a manner that the resultant frequency response of the video replay head (1) and of the video head amplifier (3) is approximately linear up to this upper cut-off frequency and then drops steeply. For lowering the frequency response of the video head amplifier (3), a correspondingly dimensioned frequency-dependent feedback branch (17) from the output (16) of the video head amplifier to its signal input (18) is advantageously used. <IMAGE>

Abstract: A thin film, solid state device (10) includes a conductive thin film (20) formed on a substrate (14) with a resistive layer (22) overlying the conductive thin film and with electrical contacts (30,32) formed on the upper surface of the resistive layer. Electrical current flows between the electrical contacts through the resistive overlayer and the conductive thin film. The resistivity and dimensions of the resistive layer are such that, preferably, only a small fraction of any current flowing between the electrical contacts will flow solely within the resistive layer, yet the magnitude of the current will not be reduced below a desired signal level due to the presence of the resistive layer. The resistive layer is comprised of material which will not diffuse into the thin film conductive layer during device processing. TaN x  is the preferred material for the resistive layer. A compound or mixture of a metal and either nitrogen or oxygen, where the compound or mixture will not diffuse into the thin film conductive layer, is also a useful material for the resistive layer (Fig. 4).

Abstract: This invention relates to catalyst supports, such as are used in catalytic converters for vehicles, and in other applications, such as diesel particulate traps. The invention discloses a novel composition for a catalyst support, and a method of making it. The support in­cludes a base material, such as a stainless steel. If the base mate­rial is a metal, it can be rolled down to the thickness of a foil and then coated with a layer of aluminum. The coating is done by a vapor deposition technique, so that the aluminum coating is thin and sub­stantially uniform. The base material can be almost any substance capable of withstanding the high temperatures expected in the catalyt­ic converter or other application. Because the material is already of foil thickness when it is coated, it is not necessary to select a material which is capable of being rolled down after being coated with aluminum. Thus, the invention makes it possible to use a much wider variety of materials than have been used in the prior art.

Abstract: A pulsed-field walk-through metal detector contains circuitry to reduce several different types of external noise, or interference due to external stationary or moving metal, and signals due to small objects, such as jewelry. A self-test fixture monitors system performance. The detector has digitally controlled timing means (210) operating at an odd half-multiple of the power mains frequency. A gated integrator (25) is active for periods equal to a multiple of the TV retrace frequency. A switched-capacitor FIR filter (260) removes signals due to steady power line hum, and a subtractive means removes signals due to stationary metal, prior to averaging or lowpass filtering. A peak limited (263) controls transient noise bursts. A voting circuit (300) reduces the likelihood of false alarm triggering. A simple self-test circuit, consisting of a wire loop (120) and a switch (121), tests the entire signal path and has no moving parts.

Abstract: In the method for the automatic frequency control of semicon­ductor lasers, the signal emitted from the laser (1) is sent to an optical resonator (6) whose resonance frequency is modulated by a ramp signal, the signal outgoing from the resonator (6) is converted into an electrical signal, the derivative of such an electrical signal is calculated, the zero crossing of the derivative is detected, the ramp signal is sampled in correspondence with such a zero crossing, and the sample thus obtained is algebraically summed to a reference signal dependent on the nominal laser emission frequency, thus obtaining an error signal which is sent to devices (3) driving the laser (1). In case of a plurality of lasers (1a..1n) the signals of which are wave­length multiplexed, the ramp signal is sampled in correspondence with the derivative zero crossings corresponding with the emission frequen­cies of the individual lasers (1a..1n), and the samples thus obtained are compared with respective reference signals, obtaining a control signal for each laser. 
     A device for implementing the method is also supplied.
