Abstract: A stock size intended to be added as a solution to the pulp stock in connection with the manufacture of paper or board in order to improve the characteristics of the paper or board, e.g.), to reduce the absorption of liquids, to increase the dry strength and wet strength. The stock size contains a polymer, which is based on styrene maleic acid and stabilised with a polysaccharide, such as cationic starch. The stock size is advantageously prepared in a steam jet cooker. The stock size is suitably used as a stock size in the manufacturing of liquid packaging board.

Abstract: A method of continuous production of ice-solution suspension wherein the solution being continuously fed (7) to the processing zone (6) is overcooled: then, the turbulization (14) is performed in the overcooled solution; as a result, ice microcrystalls are formed in the solution; after that, the formed ice-solution suspension is removed (8) from the processing zone, in doing this, the said turbulization is chosen with such intensity that the formed ice microcrystalls mass transfer balance will be positive, considering their adhesion on the internal surfaces in processing zone. An installation (1) for continuous production of ice-solution suspension is also described.

Abstract: An intermediate for a mailer type business form is provided that is Z-folded to produce a mailer type business form with built-in reply envelope. The mailer type business form is adapted to be used either as a mailing label or as a one-piece mailer. The mailer is of compact size, for example, about 7 inches×4 inches so as to facilitate its use as a mailing label on relatively small packages. First and second panels of the mailer define a reply envelope when the mailer is Z-folded. The third panel of the mailer is adapted to include invoice and/or remittance advice and may include a line of weakness to define a stub that can be inserted in the reply envelope with a check. The intermediate is printed in a rotated format to provide two forms about fourteen inches and also has rewettable glue and additional cohesive to create a postal compatible reply envelope.

Abstract: An apparatus for monitoring one or more gas components in a fluid wherein either a) a sample gas obtained from the fluid is enriched in at least one target gas which is to be subjected to analysis; b) at least one target gas which is to be subjected to analysis is separated from a sample gas obtained from the fluid; or c) both.

Abstract: A dual- or multi-layer filter medium for air filtration, having at least one meltblown layer (2, 2a and 5) at least one meltblown layer (2 and 2a) is placed on the inlet side of the filter medium. The meltblown layer has a pore size larger than that of the next following layer or layers.

Abstract: When a mobile terminal in a mobile radio network has a user data connection established to a core network node, and receives a page message on a paging channel from a second core network node to which the terminal has no data connection established, the mobile terminal can send a page response message to the second core network node on the existing signaling channel between the mobile terminal and the radio access network associated with the established data connection to that core network node. The page response then triggers a multiplexing between the mobile terminal and radio access network, of the established connection with the first core network node and the desired call connection (precipitated by the page request) from the second core network node. This way, the mobile station can receive simultaneous calls from two different core network nodes over a common traffic and signaling connection.

Abstract: A very small sized and highly efficient RF ground breaker for use in magnetic resonance imaging (MRI) is constructed on a printed circuit board. A variable capacitor is used to tune the ground breaker to block the desired radio frequency signals from passing along the outside of a coaxial cable conductor. Preferably, the printed circuit board is double-sided with the ground breaker components being mounted on both sides and with RF conductors being mounted within recesses and serving to interconnect printed circuit traces from one side of the circuit board with those on the other side. In a double ground breaker version, undesirable coupling between proximate RF ground breaker components associated with separate channels are purposely intercoupled by capacitance designed to substantially cancel unwanted inter-channel coupling effects.

Abstract: A method of splicing optical fibres is described in which at least one of the fibers has a high numerical aperture (NA) and the two fibres have different mode spot sizes. The method comprises fusing the ends of the fibres together with their cores in alignment and heating the fused junction between the fibres so as to cause dopant to migrate out of the core. The heating step is carried out for a time sufficient to achieve a predetermined level of matching between propagation modes in the two fibres.

Abstract: Novel hydantoin derivative which is represented by the formula: ##STR1## (wherein X and Y represent a halogen atom, R.sup.1 represents a hydrogen atom, an alkyl group, a cycloalkyl group, an alkenyl group or an alkynyl group, R.sup.2 represents a hydrogen atom, an alkyl group, an alkenyl group or an alkynyl group, and R.sup.3 and R.sup.4 independently represent a hydrogen atom or a lower alkyl group), and a herbicide containing said derivative as effective ingredient.This hydantoin derivative exhibit excellent weed-killing activity for harmful weeds and low phytotoxicity for crop plants.

Abstract: A communication network comprises a number of slotted rings which interconnect nodes so that information is carried between nodes in the form of slot sized packets on each ring. Each node includes controller for controlling the maximum acces delay experienced by packets belonging to the synchronous services, and selector for allowing any synchronous connection to utilize the first available ring for transmission of packets.

Abstract: Transverse sub-chambers are defined beneath a train of kiln cars. Pressure equalization is permitted with respect to the firing chamber thereabove but very little air will actually pass therebetween because there is no other substantial air passageway leading into or out of the sub-chamber. Rather, heat exchange cooling apparatus is employed in each sub-chamber so as to set up convention air currents within the sub-chamber to cool the underside of the kiln car. The heat exchanger units in different sub-chambers are preferably individually controllable so as to provide a controllable degree of undercar cooling as a function of location along the tunnel kiln.
