Abstract: There is provided a periodic definition on the same fragments of a linear signal of the transmitter and the receiver of parity and oddness of quantity of blocks 10 and 01, corresponding to characters 1 and 0 of initial signals. In case of oddness of quantity of blocks in the transmitter and the receiver a combination 10 is formed, in case of even quantity - a combination 01 is formed on two auxiliary clock intervals. On the first interval the information concerning parity and oddness of quantity of blocks 10 of useful signals is placed, on the second one, the parity and the oddness of quantity of blocks 01 is placed. On the basis of discovering the prohibited combinations in the receiver the location of the clock interval damaged by single errors is defined. The blocks placed on auxiliary intervals generated in transmitter and the receiver are compared among themselves and in case of an incongruity of the received results the command on creation of the block of a useful signal corresponding to the interval containing various characters is worked out. An error is corrected by substitution of the prohibited combination placed on an interval by the block which has been worked out as a result of the specified command. Items: 1 independent

Abstract: An electronic ballast circuit for fluorescent or other gaseous discharge lamps includes a resonant half-bridge inverter circuit.  The source voltage to the inverter is a full-wave rectified line voltage together with a DC carry-over voltage for supplying power in the inter-cusp period of the rectified line voltage.  A negative feedback circuit is responsive to lamp current to vary the inverter drive frequency and thereby regulate lamp current.  The frequency response of the feedback loop is high enough and the gain-versus-frequency response of the inverter is such that lamp current and voltage are regulated to reduce the crest factor of lamp current to compensate for variation in the amplitude of the voltage across the semiconductor switches.

Abstract: POLYHYDROXYL COMPOUNDS CONTAINING A SULFONIC ACID        ESTER GROUP          ABSTRACT OF THE DISCLOSURE    The invention relates to a process for the preparation of a polyhydroxyl compound which contains at least one sulphonic acid ester group prepared by (i) reacting a paraffin sulphochloride with an alcohol in the presence of a hydrogen chloride acceptor to form a solution of the polyhydroxyl compound in an organic phase, (ii) dissolving the organic phase in a suitable solvent, (iii) washing, dewatering and removing the solvent by distillation.  The polyhydroxyl compound thus formed is suitable for the preparation of polyurethane cast resins.

Title: Semelle antirecul polyvalente pour ski de fond
Inventor: LONGERAY REMI
IPC: A63C5/056
Filed: 1986-09-29
Granted: 1990-12-11
Abstract: DE DIVULGATION: Cette semelle est essentiellement constituée, dans la ou les zones auxquelles est rattachée la fonction antirecul, d'un matériau qui présente une hydrophobie élevée, une bonne résistance à l'abrasion et des propriétés de visco-élasticité très sensibles à la vitesse de déformation et à la directionde la sollicitation et telles qu'il se produise, durant la phase d'impulsion, un comportement permettant une certaine pénétration des cristaux de neige, alors que, durant la phase de glisse, ledit matériau présente une élasticité élevée permettant le dégagement rapide des cristaux de neige quelles que soient la température ou la nature de ces cristaux, la topographie de la surfacede la semelle étant, par ailleurs, caractérisée par la distribution des hauteursde profil de sorte qu'elle soit compatible avec la granulométrie des différents types de neige. Selon l'invention, ce matériau est choisi parmi les polyuréthanes obtenus par polycondensation de polyols présentant une chaîne hydrocarbonée possèdant de huit à vingt atomes de carbone entre groupements fonctionnels hydrophiles et de di-isocyanates. Ces di-isocyanates sont choisis de préférence parmi le méthanediphényl-di-isocyanate (MDI), le toluene-di-isocyanate (IDI) et l'héxaméthylène-di-isocyanate (HDI) employés seuls ou en mélange.

Title: Valve
Inventor: TURNER LARRY G
IPC: F16K25/00
Filed: 1986-10-15
Granted: 1991-09-10
Abstract: ABSTRACT OF THE DISCLOSURE A three-piece angle stop valve comprises a valve body, resilient control sleeve and handle, with no separate fastening or sealing elements required. Inlet line pressure resiliently biases the side walls of the control sleeve and a circumferential sealing flap formed thereon into sealing engagement with the valve bore to prevent leakage. The handle is secured to the valve body by resilient formations which snap into a circumferential groove on the valve body. The handle rotates the control sleeve by means of telescoping splines. Several circumferential and axial reinforcing ribs are formed on the interior of the control sleeve

Title: Process for increasing the degree of oil extraction
Inventor: ELLINGSEN OLAV
IPC: E21B43/00
Filed: 1986-12-02
Granted: 1991-03-05
Abstract: A process for increasing the degree of oil extraction.         Abstract A process for increasing the degree of extraction of oil or other volatile liquids in oil reservoirs on land or at sea, by making the formations in said reservoir vibrate as close to the natural frequency of said formations as possible, so that the binding forces between formations and oil are de-graded and oil  is, thus, more easily recovered from the form-ations. Furthermore, the pressure in said reservoir is main-tained by evaporating some oil and water in the reservoir, due to the fact that heating is achieved both as a consequence of said vibrations, and by the aid of electrical high frequency pulses causing the reservoir to perform like an electrode furnace.

Title: Loaded paper
Inventor: SINCLAIR PETER

Abstract: ABSTRACT                         LOADED PAPER            Aqueous suspensions of papermaking fibres and filler are each separately treated with an anionic or a cationic polymer, after which the filler (preferably) or the papermaking fibre is treated with a polymer of opposite charge to that used in the initial treatment.   The filler and papermaking suspensions are then mixed to form a papermaking stock, with dilution as necessary before, during or after the mixing operation.   This stock is then used to form a loaded paper web in conventional manner.          The initial treating polymer is preferably a papermaking retention aid or flocculant, e.g. a cationic polyacrylamide or an amine/amide/epichlorohydrin copolymer in the case of cationic materials or an anionic polyacrylamide in the case of anionic materials.   The further treating polymer is preferably an anionic or cationic starch, depending on the charge of the initial treating polymer.
