Abstract: ABSTRACT An oil-spill-combatting water craft is provided with at least one protruding boom but most suitably one on each side of the craft.  Each boom directs surface water and oil present in it into a conduit inside the craft, the inlet and the outlet of the conduit being located in the side of the craft. The purpose is to provide a simple, high-capacity arrangement in which the flow is, nevertheless, relatively calm even when the sea is rough.  With this in mind, the conduit has been implemented as a circulation conduit, the outlet of which is situated nearer the bow than the inlet and in which the water flows automatically owing to the water-raising and water-guiding effect of the boom. Separating means for water and oil is fitted inside the conduit, is a rotating arrangement which allows water to flow through and is, for example, made up of rows of bristles.  In front of the outlet of the conduit there is fitted a baffle which extends obliquely outwards and backwards.

Abstract: ABSTRACT OF THE DISCLOSURE     The invention disclosed in this application relates to leavener-containing dough compositions, methods of making such compositions and baked compositions prepared therefrom having a storge-stable soft and plastic crumb matrix.  The compositions comprise a flour-based dough bakeable to a chewy texture in admixture with a heat-activated leavening agent which releases effective amounts of a leavening gas when the dough reaches the activating temperature of the leavening agent during baking.  The activating temperature of the leavening agent is such that the leavener is releasing effective amounts of the leavening gas at a stage during the baking of the dough at which ingredients of the dough set-up to form the crumb matrix.

At each decrement, complexes are detected by investigating the signal slope, and peaks of the complexes are measured an compared.  During the complex detection process, the signal slope is measured periodically at a rapid rate, and unless the slope meets predetermined criteria, the input filters are clamped to a baseline, and the process is repeated.

Abstract: ABSTRACT            A wide band local communications system handling both circuit switched and packet switched communications has a number of units accessing a common unidirectional trans-mission line, which may be folded, on which circuit switched and packet switched communications are organized into hybrid frames comprising a region for each communication type.  Each unit is in communication with a number of communication stations or a control centre which carries out centralized functions.  The access units cooperate with one another and with a frame signal generator, either controlling or associated with each unit, to implement in a distributed manner an ordered collision free round robin protocol in both frame regions, based on physical unit location.

Abstract: Abstract of the Disclosure An arc spray gun has a generally frusto-conical head member of electrically insulating material, with the small end facing forwardly in the direction of spray.  Wire is fed through a pair of electrically conductive tubular wire guides containing pressure contact means that extend through the head member and converge to contact the wire ends for arc formation and melting of the metal.  A gas jet nozzle provides compressed gas for atomization and spraying of the molten metal.  A first gas cap is disposed coaxially on the head with rear and forward gas seals so as to define an annular gas chamber.  A secondary gas is supplied to the annular chamber, and the first gas cap has a pair of diametrically opposite orifices therein for directing the secondary gas from the chamber to modify the molten metal spray in a fan shape.  The orifice may have elongated cross sections to produce a rough coating surface if desired.  A second gas cap is adapted to replace the first gas cap in sealing relationship with only the rear gas seal so as to provide, as an option, an annular flow of the secondary gas about the wire ends.  A pair of hose assemblies supply the primary and secondary gases separately to the gun, as well as wire and arc current.  A distribution block on the gun separates the gas flow and metal wire from the hose assembly.

Abstract: (57) ABSTRACT OF THE DISCLOSURE       This publication describes an apparatus for wrapping different sizes of paper rolls (1) or rolls of like material into a wrapper by rotating the rolls (1).  The apparatus comprises a support frame (2) encompassing the roll (1), means for conveying the wrapper on the roll (1), and at least one flexible guide band (3) which is devised to press on the outer surface of the roll (1) and to comply with the rotating of the roll.  In the apparatus according to the invention, the guide band (3) is configured into an endless conveyor with an at least approximately U-shaped form, within which the roll (1) to be wrapped is inserted. The inner loop (4-5-6-7) of the conveyor is configured to pass over four such guide rollers (4...7), mounted on the two first lever are (8, 9) and the two second lever arms (10, 11), are capable of being transferred against the outer surface of the roll (1) to be wrapped.  Then, the guide band (3), which passes over the guide rollers (4...7), during the wrapping phase touches the surface of the roll (1) to be wrapped at each point within the three circumferential segments (4-5, 5-6, and 6-7) between the guide rollers (4...7) on the outer surface of the roll (1) to be wrapped.

Abstract: Abstract A rock drill having a tunnel profile control system comprises a boom assembly, a converting unit for convert-ing the position of one of various positioning points on an orthogonal coordinate system representative of the transverse section of a tunnel to be driven, into a respective value on a boom coordinate system.  A position-ing control positions the boom assembly according to a value from the converter unit, and an ultrasonic distance measuring instrument mounted on the boom assembly determines the distance between the positioning point and a point on the peripheral wall defining the tunnel.          An arithmetic unit utilizes the distance measured between the positioning point and the point on the peripheral wall defining the tunnel, the direction of travel of the ultrasonic waves, and the value of the positioning point, to calculate, in terms of the value in the orthogonal coordinate system, the value of a measuring point on the transverse section of the tunnel.  The arrangement achieves easy and exact measurement of the profile of the tunnel being driven.

Abstract: Abstract of Disclosure The present invention relates to a process for the preparation of aldehydes by the reaction of olefinic compounds with hydrogen and carbon monoxide in the presence of a catalyst system containing rhodium and aromatic phosphines.  The aromatic phosphines are soluble in organic media and represent salts of sulfonated or carboxylated triarylphosphines which are insoluble in water.  After hydroformylation, the reaction product is treated with a diluted aqueous solution of a base and the aqueous phase containing rhodium and aromatic phosphines is separated.  Thus, thermal loading of the catalyst, for example by the redistillation of the reaction product, is avoided.

Abstract: ABSTRACT OF THE DISCLOSURE        When blow molding elongated serpentine tubes or similar articles, loading of the mold cavity with the parison can present a problem.  The parison can stick against the wall of the mold cavity.  Moreover, a large diameter parison must be used, i.e. the parison must have a diameter equal to the total width dimension of the article, and consequently a large volume of flash is produced.  The flash must be trimmed and recycled.          In order to avoid these problems, inserts are placed in the mold to define portions of the mold cavity, particularly at corners.          Air under pressure is fed into passages in the outer surfaces of the inserts and discharged through small orifices in such inserts against the parison to guide and drive the latter fully into the mold cavity.  A vacuum can also be applied to the end of the cavity remote from the parison entry point for drawing the parison into the mold.
