Abstract: MACHINE FOR CLEANING OUTER SURFACE OF PIPES        OF A MAINLINE         Abstract of the Disclosure The invention relates to machine for cleaning outer surface of large-diameter pipes from dirt and anticorrosive coating during repair of mainlines, in particular, oil and gas lines without interruption of supply of a product transported along the pipeline. The machine comprises a self-propelled carriage which is moved, during cleaning, over the surface of the pipe being cleaned axially thereof. The carriage frame supports a working member having a hollow casing accommodating an annular rotor coaxial with the pipe being cleaned, the rotor supporting cleaning tools. The casing and the rotor are made detachable each consisting of two half-rings, one half-ring of the casing being the top half-ring which is rigidly secured to the frame of the self-propelled carriage, and the other casing half-ring is the bottom half-ring. The bottom half-ring of the casing and one half-ring of the rotor are made detachable each consisting of two hinged parts of substantially the same length which are articulated with the ends thereof to the ends of respective half-rings for rotation relative to the half-rings on either side of the axis of the pipe being cleaned, whereby the distal ends of the hinged parts can be moved apart at the points of deta-chment for mounting and dismantling the machine on the pipe being cleaned. The top half-ring of the casing has a device for securing the rotor thereto after bringing together the mating planes of the hinged parts of the casing and rotor.      This construction of the machine reduces the time needed for its mounting and dismantling on an operating pipeline and cuts down labour-consuming operation thus improving the productivity of the machine as a whole.

Abstract: ABSTRACT OF THE DISCLOSURE     The present invention relates to a special copolymer solution consisting of acrylic resin containing 70 to 90 % by weight of copolymer solids and 10 to 30% by weight of solvent.        The invention also relates to a process for the manufacture of the copolymers which are present in the copolymer solution; additionally, the invention relates to the use of the copolymer solution for the manufacture of coating compositions for lac-quer systems of low solvent content which contain polyisocya-nates and which contain the copolymer manufactured according to the invention as a resin component which carries hydroxyl groups.        The outstanding advantage of the copolymer solutions manufactured according to the invention resides in the fact that it is possible for the hydroxyl groups of the copolymers to crosslink with polyisocyanates at room temperature and also at elevated temperatures and to produce lacquers of high solids content.        Compared with the known copolymers, the copolymers manufactured according to the invention display the following advantages in the combination with polyisocyanates:  better solvent-resistance, higher abrasion resistance and better resistance to weathering in the Florida climate. Moreover, the clear lacquers or pigmented lacquers do not exhibit crater formation or blistering.        The copolymers can be employed, together with polyiso-cyanates, for the production of coatings or coverings in the reactive lacquers, on substrates of the most diverse types, for example porous or non-porous substrates, such as textile non-wovens, leather of plastics. In every case high-gloss, pore-free, elastic and solvent-resistant coating having a very hard surface are obtained.

Abstract: Abstract of the Disclosure A specific and sensitive method for the determination of .alpha.-amylase activities in a sample is disclosed.  The method utilizes a partially modified starch substrate which contains blockages to the action of exo-carbohydrases but not to .alpha.-amylase, an endo-carbohydrase. Cleavage of the modified substrate by .alpha.-amylase leads to free nonreducing ends which can then be attacked by a suitable exo-carbohydrase serving as the coupling enzyme. The reaction sequence is as follows:  Blocked starch .alpha.-amylase  unblocked starch phosphoglucomutase inorganic phosphate  glucose-1-phosphate phosphoglucomutase glucose-6-phosphate glucose-6-phosphate dehydrogenase, NAD NADH.  The rate of increase of absorbance due to NADH formation can be measured to determine the level of .alpha.-amylase activity in a sample, particularly one of serum or urine origin.  The values obtained are useful in clinical diagnosis.

Abstract: METHOD AND APPARATUS FOR AUTOMATIC ULTRASONIC FLAW DETECTION          Abstract of the Disclosure Method and apparatus for automatic ultrasonic flaw detection of pipe welding zones wherein the width of the weld zone is divided into a plurality of subdivisions.  The ultrasonic energy received from each of the subdivisions is displayed by employing multichannel gate circuitry providing respective outputs in units of 10% of the height of the echoes in each subdivision on a cathode ray tube in synchronization with signals representative of the longitud-inal and lateral position of the probes along the pipe with respect to a reference point.  The height of the defective echoes in each gate are printed together with the positions of the probe.  The positions of the defects are diagrammed by a computer, thereby enabling high-speed data processing of the flaw detection information, a decrease in the time for precise flaw detection comparable to conventional manual flaw detection method and apparatus and easy determination of the flaw detection results.

Abstract: DIFFERENTIAL PRESSURE DRYING AND SOLVENT RECOVERY UNIT     Abstract of the Disclosure A web of solvent bearing material is passed through a series of spaced apart solvent stripping slots while at the same time gas streams are sucked through the slots to float the web in the slots and to strip solvent from the web.  In a preferred embodiment the gas stream is heated before it enters the slots and the web is heated between slots to enhance and increase the vaporization rate of the solvent and the gas streams and solvent vapors leaving the slots are conveyed to a fractional condenser which condenses the solvent, and if the solvent is a solvent other than water, separates the water which might be present from the solvent, and collects the solvent for re-use.  An improved drying apparatus is disclosed for maintaining a stable contin-uous partial vacuum upon the web passing through the apparatus while providing for both an upstream and a downstream flow of gas over said web.

A piston is slidably received in the working cylinder and has a piston rod that extends through the main body and across both of its ends.  The piston is resiliently pressed against the lower end of the main body in an inoperative position.  The operating handle of the tool is mounted about the main body and is also resiliently pushed toward an inoperative position which cor-responds to the inoperative position of the piston.  The lower end of the piston has a forming head device intended to be moved over the rivet slid over one of the mandrels to crimp it there-over.  The pressure fluid is fed lengthwise of the rod to move the piston and thus the forming head toward the rivet-holding mandrel.  Finally, an indicator mechanism is provided both on the piston rod and on the handle so that pressure fluid is fed as soon as the handle is moved from its inoperative position.
