Patent FI-891157-A (FI)
Inventor: DEN HOLLANDER WILLEM
IPC: H04N7/025
Filed: 1989-03-10
Abstract: A teletext decoder includes a background or buffer memory (45) operating as a first-in, first-out (FIFO) memory. The buffer memory (45) is used for storing a large number of teletext pages. A given video line that contains teletext information is identified as such by the detection of part of a clock run-in sequence followed by the framing code. The video line is then stored in the background memory (45). After a user page request occurs, the background memory (45) is read-out by a data processor (30) operating in a full channel mode of operation for obtaining the information of the requested page. As long as the read-out operation has not been terminated, incoming teletext data is stored in the background memory (45). This enables teletext data received prior to termination of the read-out operation to be read out and processed by the data processor.

Abstract: The present invention relates to a novel sizing composition in the form of an aqueous emulsion comprising a hydrophobic cellulose reactive sizing agent and a cationic polymer comprising a starch, the novel features of said composition being that the starch possesses a combination of (A) a branched, high molecular weight structure as reflected by an amylopectin content of at least 85% and (B) a degree of substitution of about 0.05 to 0.40. Such sizing compositions can be prepared by dissolving the aforementioned starch in water, adjusting the temperature to above the melting point of the sizing agent and adding the sizing agent to the solution so as to form a coarse emulsion , which is subsequently subjected to shear forces to reduce the particle size of the emulsion. The invention also relates to a method of preparing sized paper or paperboard by using the above-mentioned sizing composition. Also, the invention relates to the sized paper for paperboard prepared by said method. Such paper products show reduction in liquid absorbency as compared to products using conventional sizing agents, reduced consumption of optical highteners, and enhanced development of sizing.

Title: Improvements in the manufacture of alkali nitrates
IPC: C01D9/04
Filed: 1933-01-14
Abstract: In the production of sodium or potassium nitrate from the corresponding chlorides and nitric acid in the presence of lead oxychloride with regeneration by lime of the lead chloride precipitated in the reaction, the crude solution of nitrate obtained is treated with an alkali, or with an alkaline-earth such as lime to free it from dissolved lead and the lead oxychloride precipitated is filtered off.  The mother liquor remaining after crystallizing the alkali nitrate, after addition of the alkali chloride required for the next cycle and preferably also in presence of some lead oxychloride, is treated with sulphuric acid to eliminate calcium as sulphate.  Nitric acid and regenerated lead oxychloride are then added for the production of more alkali nitrate.  The whole or a part of the lead chloride precipitated in the reaction is dissolved in calcium chloride solution with or without calcium acetate and sulphuric acid equivalent to the amount of oxychloride present added, the calcium sulphate formed carrying down impurities which are filtered off.  All the lead chloride is then converted to oxychloride for re-use by means of lime.  Purification of lead chloride need not be affected at each cycle, particularly if an excess of chloride be maintained in circulation in the cycle.

Abstract: 1278231 Amplifiers PLESSEY CO Ltd 5 Jan 1971 [10 Jan 1970] 1307/70 Headings H3Q and H3W  In a control arrangement for maintaining a power amplifier, and more particularly, a travelling wave tube, at the point A, Fig. 1, of maximum power output, an amplitude modulator 18, Fig. 2 is provided, operating from a modulation generator 14, to add an incremental component, i.e. proportional to the slope g, Fig. 1, to the input drive to the amplifier 4. A fraction of the output power of the amplifier is branched off by means of a coupler 6 and rectified by a detector 8, which may have a square-law characteristic. The demodulated output from detector 8 is amplified by logarithmic amplifier 10 and applied to phase-sensitive detector 12, in which it is compared with the original modulating signal, derived over time delay or phase correction circuit 16. The output from phase-sensitive detector 12 is compared with a reference voltage, representative of the slope g, Fig. 1, at the desired working point, in resistive combining network 24. Any difference is amplified and smoothed by integrating amplifier 20, and used to control the drive to the amplifier, in input control element 22, which may comprise a PIN diode attenuator. The modulation signal may comprise a random or semi-random waveform, and the arrangement can also be used to control pulsed input signals: if the pulses are too short for the gain control loop to be effective within one pulse duration, the feedback and reference signals can be gated into the integrating amplifier in synchronism with the pulses so as to provide a control signal which is averaged over several pulses: preferably the modulation generator is then used to generate alternative positive and negative pulses so as to avoid synchronous gating out of the control modulation by the pulse timing.

IPC: C23G1/32
Filed: 1957-01-14
Abstract: Titanium or zirconium or alloys thereof are descaled after heat-treatment by being treated with a heated alkali metal pyrosulphate or an alkali metal borofluoride or a mixture thereof. In the example, a zirconium alloy containing Hf 2-3% and C up to 0.03% was annealed at 600 DEG C. for 30 minutes and descaled in (I) molten sodium pyrosulphate, and (II) molten sodium borofluoride.  The alloy was finally pickled in a bath containing 6HF/45HNO3.  Where the heat-treatment temperature is 650 DEG C. and above, the scaled metal is preferably hot-rolled prior to descaling.  Where the heat-treatment temperature is 900 DEG C. and above, the metal is preferably descaled in a mixture consisting, by weight, of 80% pyrosulphate and 20% boroufloride.  According to the Provisional Specification, descaling may also be effected in molten alkali metal fluoride or in hot concentrated sulphuric acid.  15% by weight of an oxidizing agent such as sodium nitrate may be added to the latter if the metal to be descaled has been annealed at 850 DEG C. and hot-rolled at this temperature.

Abstract: 1377842 Adjustable back rests O MAYER 12 Jan 1972 [15 Jan 1971] 1468/72 Heading A4J [ Also in Divisions E1-2] In a lockable joint suitable for use in adjustable seat backs, two arms 10, 12, pivotable about axis 14, are locked when spring urged member 18 attached to arm 10 engages a notch i.e. 30, 30a, 30b in a peripheral edge 20 of arm 12 and an unlocking lever 140, also pivotable about axis 4 has an eccentric cam 145 crossing the edge 20 to lift the member 18 to the unlocked position shown and retain it there. In the embodiment of Fig. 5 and Fig. 4 (not shown) the member 18 is retained in the unlocked position on a portion 150 which extends at right angles to the direction of movement of the member. A frictional connection between the lever 140 and the arm 12 causes the lever to move anti-clockwise with this arm when the joint is moved to the open position allowing member 18 to slide off portion 150 and lock in the next position 30a. However in any closing movement of the joint the lever 140 is prevented from moving by its abutment with arm 10 so that in this direction re-locking is prevented. Further embodiments which operate in this manner are given Figs. 10, 13-16 (not shown) and the device may be adapted to operate in the opposite manner i.e. to lock in every position as the joint is closed while moving freely when opened Figs. 6-9 and 12 (not shown). In Fig. 20 and Figs. 17-19 (not shown) the unlocking lever operates in a different manner to retain the member 18 in the unlocked position. At the point shown the unlocking lever 538 has just been moved anti-clockwise to the unlocked position, member 18 having moved up cam 542,' past maximum displacement point 545 to clear the notch 530a and to rest on cam 542', being prevented from re-locking by the engagement of the lever with stop 582. When the joint moves to the open position member 18 can slide down cam 542' to lock in notch 530. To unlock from this position the lever is moved clockwise - the cams reverse their functions and the member 18 slides up cam 542'to come to rest on cam 542," being held there by the engagement of face 584 with the stop 582. The joint will lock in all positions whether it is being opened or closed and any number of notches may be used provided that a double cam portion as shown is provided between every pair. The joints may also be used between ladder sections for camp beds and in collapsible perambulators.
