Title: Improvements in or relating to electric current converter circuits consisting of semi-conductor rectifiers
IPC: H02M7/06
Filed: 1959-03-24
Abstract: 886,555. Rectifying. SIEMENS-SCHUCKERTWERKE A.G. March 24, 1959 [March 25, 1958], No. 10148/59. Class 38 (2). To protect silicon or germanium rectifiers 7 to 12 in a bridge circuit against overloading due to carrier storage when the potential is reversed, a condenser 15 is connected across the D.C. output leads, as close as possible to the connections between the output leads and the rectifiers, its capacitance being one order of magnitude greater than the total effective capacitance measured between two points such as P and Q when rectifier 8 has just stopped conducting. If the capacitance of the polyphase source is negligible this will be equal to approximately ten times the sum of the capacitance of one rectifier 8, when blocked, and the effective capacitance of two rectifiers in series, 7 and 9, when blocked, i.e. about fifteen times the capacitance of a single rectifier in the blocking condition. Each rectifier may be replaced by a series, parallel, or series-parallel combination of rectifiers. A resistor having a low self-inductance may be connected in series with the condenser. Specification 855,725 is referred to.

Title: Process for the production of chemically resistant urea-formaldehyde resins
IPC: C08L61/24
Filed: 1951-05-04
Abstract: Urea-formaldehyde resins are rendered chemically resistant by incorporation of up to 30 per cent. of resinous epoxides prepared by condensation of dihydric phenols with epichlorhydrin or dichlorhydrin in alkaline medium.  Catalysts for hardening the resinous epoxide e.g. amines such as dimethylaminoethanol, or bis 1,3-dimethylaminoisopropanol may also be added.  The urea formaldehyde resin may be alkylated e.g. with butanol.  In the example to 100 parts of a butanol solution of a urea-formaldehyde condensate are added 4 parts of a condensate from p.p1-dichlorodiphenyldimethyl methane and epichlorhydrin.  4 parts of a 1 per cent. benzene solution of bis-1.3-dimethylamino-iso-propanol are also added.  The result is a baking lacquer yielding films resistant to attack by acetic acid and caustic soda.

[Class 22] [Also in Groups VI and VIII] Surgical plaster bandages are made by coating a fabric or like backing with a mixture of anhydrous or semi-hydrate plaster, a waterswellable binder, and hot water, and subsequently drying, the temperature being maintained during these operations above that at which the plaster sets to any substantial extent, for example above 90‹ C. and preferably near 100‹ C. As shown a fabric web 18 passes through a slit 8, into a steam-jacketed vat 1 containing the plaster mixture 10, and is carried around a roller 12 in the mixture and a roller 13 co-operating with a scraping blade 14, and through a slit 15, into a drying chamber 2 having a hot-plate 16 and a suction pipe 17. The vat 1 has a stirrer 11 and may be entirely closed to prevent drying of the mixture 10 or may have a perforated pipe 9 for the supply of steam, moist hot air, or other, preferably moist, heating fluid. To make the mixture, water is introduced into the heated vat through a funnel 7, followed by the binder and thereafter by the plaster, added very slowly to prevent cooling. Suitable binders are water-soluble resinates, gum arabic, starch, gum tragacanth, gelatine, casein, dextrine, alkyl celluloses, and cellulose esters soluble in hot and cold water. A suitable composition comprises dextrine 23 parts, water 500 parts, plaster 900 parts. To increase flexibility in the bandages, a plastifier such as glycerine (for example 15 parts), ethylene glycol, or Marseilles soap may be added. To obtain a quicker setting bandage the temperature may be allowed to fall slightly during a part of the process to produce a partial pre-setting of the plaster.

Title: Improvements in or relating to improved alcohol reacted phenol-formaldehyde bonding resins and to bonded laminates of aluminium and cellulosic sheet material
IPC: C08G8/28
Filed: 1950-05-04
Abstract: In making a heat-hardenable bonding resin by condensing between 1.2 and 2.5 mols. of formaldehyde or a polymer thereof with a mol. of phenol or a mol. of a mixture of phenol with minor amounts of alkyl or aryl substituted monohydric phenols at a pH between 8 and 9.5 in the presence of a strong alkali, dehydrating the resulting resin and reacting the product with a saturated lower aliphatic monohydric alcohol containing 2 to 5 carbon atoms, the reaction of the alcohol with the dehydrated resin is continued until the reaction product has a gelation speed of 30 to 180 seconds, the gelation speed being the time in seconds required to yield a gelled mass when 1.5 grams of the reaction mixture is placed in a 3/8 inch by 3 inch glass tube and maintained at 121 DEG  C.  The dehydrated resin, e.g. after removal of 90 per cent of the water, may be refluxed with an equal weight of the alcohol, or the alcohol may be added in increments of 1 part per 10 parts of resin solids, and the mixture refluxed after each addition.  Alkalis specified are caustic soda, barium hydroxide, sodium sulphite, sodium carbonate and triethanolamine.  Alcohols specified are ethyl-, isopropyl-, isobutyl-, and n-amyl alcohols. For improved bonding strengths substituted phenols such as o-, m- and p-cresols, o- and p-tertiarybutyl phenols, the isomeric amyl and octyl phenols and o-, m- and p-phenyl phenols, are used in amount up to 40 per cent of the phenol mixture.  Dialkyl- and trialkyl-substituted monohydric phenols may also be included in the phenol mixtures in amount up to 5 per cent by weight.  The resins may be modified by incorporation of up to 15 per cent of polyvinyl acetate.  In one example, a dehydrated resin formed by refluxing formalin, phenol, o- and p-tertiary butyl phenols and tertiary dibutyl and tertiary tributyl phenols in the presence of sodium sulphite, was refluxed with alcohol, the alcohol being added in increments and the mixture refluxed after each addition. When the resin solution had attained the desired viscosity, an acetone solution of polyvinyl acetate was added and the resulting solution was diluted with aqueous alcohol.  Aluminium sheeting or foil may be coated with the resins or foils may be used in making wood laminates. Specifications 409,397 and 516,344 are referred to.
