Abstract: ABSTRACT OF THE DISCLOSURE       Apparatus for forming a component of shoulder straps for ladies garments, including a tape with a two-slot buckle sewn onto one end.  A feature of the apparatus is a pivotable buckle holding and transfer device arranged to receive horizontal buckles at  a   delivery point and pivotable through about a right angle to move the buckles from the delivery point to a threading position adjacent the operative part of a sewing machine in which latter position the buckles are disposed vertically.  Threading means are provided for advancing a free end of tape past the operative part of the sewing machine and through one slot in the vertically held buckle, and bending means are provided for bending the free end of tape towards the other slot in the buckle.  Blade means are provided for pushing the free end of tape through the other slot in the buckle and into a position adjacent the main part of tape extending from the buckle, so that adjacent parts of the tape are suitably positioned for sewing together around the central part of the buckle.

Abstract: ABSTRACT      The invention relates to a barge for continuously laying a pipeline on the sea bed from a reel which is mounted for rotation about a horizontal axis.  The pipe as it unspools from the reel is aligned, straightened and tensioned by pipe-treating tools.          The invention resides in mounting the reel near the fore of the lay-barge, and mounting the pipe-treating tools on a work plat-form.  The work platform has its bottom end pivotably coupled to the stern of the lay-barge and its top end extending toward the reel at an acute angle with the deck of the lay-barge.  The pivoted platform can be rotated by lift means mounted under the platform for controlling the discharge angle of the pipe into the water.

Abstract: Abstract of the Disclosure METHOD OF PRODUCTING WATER-SOLUBLE UREA-FORMALDEHYDE     RESINS MODIFIED WITH ALIPHATIC POLYAMINES      A method of producing water-soluble urea-formaldehyde resins modified with aliphatic polyamines, residing in that 1 mole of urea, 1.5-3.0 moles of formaldehyde, and branched aliphatic polyamines with a molecular weight of 200-440, containing 10-16 wt.% of tertiary nitrogen, are interacted at 80-100°C and pH of an alkaline medium 7.2-9.5 attained by a proper amount polyamines.  Aromatic or aliphatic sulphonic of the general formula R-SO3H, where R is aryl or alkyl, are introduced into the obtained mixture until pH of an acid me-dium 4.8-6.0 is attained.  Then an alkaline agent is added up to pH 7.2-9.5. As a result an oligomer is formed which is interacted with polyoxyethylene ether of isoctylphenol with 7-11 oxyethylene units at 100-105°C.  The ethers are taken in an amount 0.2-2.0 wt. parts per 100 wt. parts of the initial urea.      The proposed method of producing  urea-formaldehyde resins modified with aliphatic polyamines ensures the production of resins which, being used in paper industry, completely replace colophony in manufacturing offset paper.  They increase the sur-face strength of the paper and decrease dusting and picking.      The method is simple in technology and can be performed both as a continuous and batch process.

Abstract: ABSTRACT OF THE DISCLOSURE      A rolled steel product emerging from a hot rolling mill is cooled by means of a fluid so as to produce martensitic and/or bainitic quenching of the surface layer of all or part of the product.  The non-quenched portion remains at a temperature sufficient to cause tempering of the martensite and/or bainite in the surface layer to take place during subsequent air cooling.          According to the invention, the maximum temperature of the tempered surface of the product after quenching is 600 to 730°C.  The method is of utility in treating concrete-reinforcing rod, wire rod, steel sheet, and steel sections.

The catalytically-active composite is made by combining a solution of a water-soluble, catalytically-promoting metal component with a finely divided, high area, refractory oxide which is sufficiently dry to absorb essentially all of said solution.  The catalytically-promoting metal component of the resulting composite is converted to water-insoluble form while the composite is essentially devoid of unabsorbed solution.  The composite is comminuted in the presence of an aqueous medium which is preferably acidic.

Abstract: DENSITOMETER PROBE SHIELD AND WELL                ABSTRACT OF THE DISCLOSURE A vibration densitometer having a probe with a thin vibrating vane, and a feedback loop for vibration of the vane at a resonance varying with the density of a fluid in which the vane is immersed. With conventional lineari-zation, the densitometer output can indicate fluid density, operate a process control system or otherwise. A probe shield and well have solved a perplex-ing problem. In the past, the densitometer would take a calibration shift if the probe were placed in different gases or in the hollow interiors or pipelinesof different sizes or geometries or the probe was placed in the same container or pipeline with different orientations. The shield and well have solved the calibration shift problem in all of these cases. It is also an advantage of the shield and well that they improve densitometer accuracy over broad density -and flow rate ranges and decrease temperature instability and long start-up times. Perplexing phase shifts caused Inaccuracies. The well and shield have also solved another serious problem where oscillation failed. In other words, before the shield was used, a densitometer "lost lock." Unusual restricted shield perforations and ports improve operation and accuracy by limiting pitot (ram pressure), turbulence and other undesirable flow effects when the densito-meter probe and shield is immersed in either compressible or "incompressible" fluids, e.g. gases and liquids, respectively. The shield enables operation under conditions of high amplitude flow noise where operation therein is not possible without the shield.

Abstract: Abstract of the Disclosure An optical sensing head is provided for immersion in a solution carrying suspended solids and includes a chamber exposed to the solution and defining a sample path which extends through the solution.  A spray mechanism is provided which forcefully removes light attenuating deposits which may accumulate on the surfaces of the chamber structure forming the sample path.  A light beam is directed along an optical path (which includes as a portion thereof the sample path), and a light sensor is disposed at the other end of the optical path providing a signal indicative of the in-tensity of the received light.  Plumbing is provided through which the exposed chamber may be flooded with clear water to thereby provide a low level suspended solids concentration for use as a reference.  A light ab-sorbing member is provided which is selectively posi-tioned across the optical path to provide a high level suspended solids concentration reference when so posi-tioned.  A controller receives the light sensor signal and operates to control the spray mechanism, the flooding function, and the positioning of the light absorbing member in a predetermined sequence.  The sensing head and its control system provide a suspended solids measure-ment with a predetermined scale factor over a pre-determined range and further provide a correction when the optical path or controller circuit characteristics change.  When the control is unable to properly provide the correction, an error indication is provided so that the suspended solids concentration readings will be known to be inaccurate.
