Abstract: TITLE:Heat-insulating fabric articles ABSTRACT     The invention describes heat-insulating fabric articles, for example a jacket, comprising an outer layer (17) preferably of synthetic material such as woven nylon, and a lining (19) joined together by a network of quilting seams (3) to form pockets.  Each pocket is filled with closed polystyrene beads (21) so that movement between the beads is possible but migration of the beads to other regions of the pocket is inhibited.  Such a garment is heat-insulative even when wet, and when dry promotes the formation of a static charge in the interstices between the beads.

Abstract: ABSTRACT OF THE DISCLOSURE Bubbles produced at an electrode in an electrolytic process are coalesced by providing a surface-limiting, electrically inert masking device of which at least a bottom portion is submerged in the electrolyte.  The masking device reduces the free surface of the electrolyte between the electrodes and this urges the gas bubbles together so that they coalesce, resulting in larger bubbles and less acid mist generation.

Abstract: A b s t r a c t Urea and formaldehyde are mixed in a mole ratio of about 1:2. The mixture is condensed for 30 minutes at a pH of 7.0 to 7.4 and a temperature between 80 and 85 °C. The con-densation is continued at a pH of 4.8 to 5.8 at the same temperature until the viscosity reaches values between 15 and 50 mPa,s. The mole ratio of urea to formaldehyde is ad-justed to a value of 1:1.80 to 1:1.90 by adding urea.  The condensation is continued under acidic conditions at the same temperature, until the viscosity reaches values of 35 to 80 mPa,s. At a pH of 5.8 to 6.5, the mole ratio of urea to formaldehyde is adjusted  to a value between 1.0:1.0 and 1.0:1.30 by adding urea. The temperature is allowed to drop freely. When the temperature has dropped to below 50 °C, the pH is adjusted to a value of 7.0 to 8Ø

Abstract: ABSTRACT OF THE DISCLOSURE   A welding gun of an arc welding machine is mounted for vertical reciprocal movement on a movable frame portion.  The movable frame portion is connected to a stationary frame portion by piston cylinder assemblies which upon actuation raise and lower the movable frame portion into and out of position for  locating the welding gun in position for welding together a pair of longitudinal sheet metal member edges positioned in a preselected relationship on the stationary frame portion.  A pair of clamp plates are carried by the movable frame portion.  When the movable frame portion is lowered, the clamp plates are positioned oppositely of the pair of sheet member edges respectively to move into and out of clamping engagement with the sheet member edges.  Once the sheet member edges are clamped in abutting relationship, the welding gun is advanced downwardly on the frame movable portion in a vertical linear path.  A welded seam is formed the full length of the abutting sheet member edges to form a welded joint at the abutting sheet member edges.  Upon completion of the welded seam, the movement of the welding gun is automatically reversed to return the welding gun to its initial raised position on the movable frame. Followed by release of the clamps against the welded sheet member edges, the movable frame portion is moved to a raised position on the stationary frame portion to permit removal of the welded sheet member edges from the stationary frame portion.   In this manner a selected number of sheet members can be welded together at their abutting longitudinal edges to form a duct section of a desired cross sectional configuration, for example polygonal or circular, in which all the welded seams are posi-tioned internally within the duct section.

Abstract: SOLID PHASE PROCESS FOR  SYNTHESIZING PEPTIDES      ABSTRACT OF THE DISCLOSURE       Thymosin .alpha.1 and other peptide amides are synthesized in the solid phase using methylbenzhydrylamine resin as the support and hydrogen bromide as the deprotecting and cleaving agents.  The N-terminal 14 amino acid partial sequence of thymosin .alpha.1, Ac-Ser-Asp-Ala-Ala-Val-Asp-Thr-Ser-Ser-Glu-Ile-Thr-Thr-Lys-OH is synthesized on benzyl ester resin. Using a mixture of hydrogen bromide, anisole and thioanisole as the cleavage and deprotection composition, the yields of the cleaved peptide and the selectivity of the deprotection is highly improved.  For example, yields of thymosin .alpha.1 have been increased by about 90% as compared to the use of hydrogen bromide alone.  By using hydrogen bromide rather than hydrogen fluoride, the synthesis can use conventional laboratory  glassware and the synthesis can be easily scaled up to commercial production.

Abstract: ABSTRACT OF THE DISCLOSURE           A circuit board having conductor tracks is optically tested for functional faults by use of a computer controlled testing apparatus including at least one camera.  The surface of the circuit board is scanned in a point-by-point manner by the camera to establish for each point scanned an image representative indicative of a conductor track area or a non-conductor track area.  The surface of the circuit board is divided into a predetermined plurality of windows of predetermined size, and the image representations are associated with respective windows.  For each window a determination is made of the sum of only the points of the window corresponding to a conductor track area or the sum of only the points of the window corresponding to a non-conductor track area.  This establishes an identification value descriptive of the particular window.  The identification values of the windows of the circuit board being tested are compared with predetermined values of corresponding respective windows of a reference master.

Abstract: ABSTRACT OF THE DISCLOSURE           Disclosed is a practical and efficient process for preparing 6-substituted 4-chromanones of the formula:       from phenolic acrylate ester compounds derivable from para-substituted phenolic or thiophenolic compounds and beta-unsubstituted acrylic acid compounds which are ester-ifiable therewith.  The process includes effecting rear-rangement of a phenolic or thiophenolic acrylate ester in the presence of a rearrangement effective amount of hydro-gen fluoride to the corresponding hydroxy - or mercapto (vinyl ketone) wherein the carbonyl carbon atom of the vinyl carboxy group is directly attached to the benzene ring ortho to the hydroxy or mercapto group.  Thereafter, the vinyl ketone is cyclized to the corresponding 6-substituted 4-chromanone in the presence of a cyclization-effective amount of hydrogen fluoride.  The 6-substituted 4-chromanones prepared by the process are useful as inter-mediates for preparing related pharmaceutical agents which are aldose reductase inhibitors used in the treat-ment of diabetic complications.
