Patent NL-6610769-A (NL)
IPC: B29C48/08
Filed: 1966-07-29
Abstract: 1,129,136. Films. IMPERIAL CHEMCIAL INDUSTRIES Ltd. 5 July, 1966 [30 July, 1965; 24 Jan., 1966], Nos. 32703/65 and 3101/66. Heading B5B. In a process for quenching a molten thermoplastic film which has been freshly extruded on to a moving casting surface and wherein an electrostatic charge is deposited on the upper surface of the cast film from an electrode situated near the film surface, and maintained at a large electrostatic potential difference from the casting surface such that the film is caused to adhere thereto, means are applied to maintain the electrode substantially free from deposits arising from condensation of vapours of volatile matter in the thermoplastic material, or from the decomposition products of such volatile matter. When the electrode is a wire, such means may take the form of (a) a scraper plate having an orifice just sufficient to allow passage of the clean wire, (b), a bath containing a solvent for the deposit, or (c) a method of reducing the contaminant concentration in the vicinity of the electrode. In the case of (a) or (b) the scraper or bath may be passed periodically along the wire, or a continuous electrode wire may be used, which is continuously moved through the scraper or bath. In case (c) an air blower or vacuum device may be used to remove the volatiles from the electrode vicinity. Another method of performing the invention consists in unwinding a clean wire from a reel at one side of the die orifice and winding the slightly contaminated wire on a reel on the other side, at such a speed that the wire accummulates substantially no deposit. Suitable thermoplastics are polyolefine polymers and copolymers polyethyleneterephthalate, polyamides, PVC, polyoxymethylene or poly -3,3-bischloromethyl oxacyclobutane. Volatile materials are U-V and heat stabilizers, and antistatic agents, Polypropylene, containing 2-hydroxy-4-methoxy benzophenone is exemplified.

Title: Image rotation circuit for VDU - uses two memories and address generators to relocate data from pixels in original image
IPC: G06T3/60
Filed: 1983-07-15
Abstract: An original image displayed on the screen is made up of lit and unlit pixels, each of which has a horizontal and vertical position in the raster matrix. A control circuit scans the raster sequentially, generating a '1' for each lit pixel and a '0' for each unlit one. These data are stored in a first memory addressed by a generator consisting of row and line counters. The control circuit calculates the co-ordinates of the corresp. pixels in the rotated image, and controls a generator which addresses a second memory. As the data in the first memory are clocked into the second memory in serial form, the second address generator selects the appropriate new pixel address for every bit of data from the old image.

Title: Phase-locked loop for signals with rectangular waveforms
Inventor: NAUTA HENDRIKUS CORNELIS
IPC: H03L7/191
Filed: 1994-12-15
Abstract: Phase-locked loop (PLL) for signals with rectangular waveforms, comprising, in series, a phase detector, a control-signal-generator circuit with a loop filter, a controlled oscillator and an auxiliary circuit. The detector receives a reference signal at a reference frequency from a reference source as a first input signal. The detector receives second and third input signals from the auxiliary circuit. The reference signal and the second input signal are compared by means of a first exclusive OR function to supply a first combination signal. The second and third input signals are compared by means of a second exclusive OR function to supply a second combination signal. The second and third input signals are such that, when the loop is in the locked state, the frequency of the second input signal is equal to the reference frequency and the frequency of the second combination signal is equal to twice the reference frequency and the power factor of the second combination signal differs from the power factor of the reference signal. The difference between the two combination signals is supplied to the control-signal-generator circuit. In the event of a frequency difference between the first and second input signals of the detector, the control-signal-generator circuit controls the oscillator in order to adjust the frequency thereof to a first extreme frequency. If the loop is not then locked, the control-signal-generator circuit will control the oscillator from the first extreme frequency to a second extreme frequency beyond the required oscillator frequency. Once the second extreme oscillator frequency is reached, the control-signal-generator circuit controls the oscillator in order to change the oscillator frequency back to the first extreme frequency.
