Abstract: ABSTRACT OF THE DISCLOSURE      The specification discloses a method of producing electrically insulating, highly flexible, solderable coatings on electrical conductors of fibre material.  The fibres or conductors are coated with a catalyst and with a solution of masked isocyanates and polyester resins which contain additives and/or auxiliary materials known in the lacquer art, and optionally compounds containing amino groups, by heating to a working temperature above 140°C. The invention is characterized in that the masked isocyanates are those which are masked with compounds with reactive hydrogen in the molecule selected from the group:  (a)  .beta.-dicarbonyl compounds which are capable of end formation; (b)  acid amides with 1 or 2 amide hydrogen atoms; (c)  hydroxyl amines and their reaction products with carbonyl compounds; (d)  imines with an imine hydrogen atom; and (e)  lactams with melting or sublimation points below about 25°C.  Moreover, the solvents are araliphatic and/or aliphatic ketones or alcohols with 1 to 10 carbon atoms and a boiling  point of at most 250°C, wherein the alcohols optionally contain ether oxygen atoms or keto groups or are esterified.  The use of such coatings substantially eliminates undesirable smells and coatings having desirable properties are formed.

Abstract: MODULAR DIE SET FOR BLOW MOLDING CONTAINERS           ABSTRACT OF THE DISCLOSURE          A modular die system is disclosed for use in blow molding an extruded plastic parison to form container members of essentially similar design but differing dimensionally.  Through use of composite die sets having modular elements, containers of different capacities can be molded without requiring complete die sets for each individual container size.  That is, die elements, used in molding a container member of one size may also serve in molding container members of a different size.  This capability is achieved through break-down of the usual integral, cavity-defining die halves of a split die set into a plurality of die elements so selected that each of them controls but two of the three dimensions of the die cavity.          Provision is made for substituting different die elements in the composite die sets and for securing these together on the platens of a blow molding press.  The system simplifies tooling inventory and cost, especially in the manufacture of larger containers having a base or tray and hinged cover or lid, where the tray and lid are of congruent form but differ in their "hardware" configurations to provide non-identical but complementary hinge and latch formations, handle provisions, and the like.

Abstract: ABSTRACT OF THE DISCLOSURE         A method and apparatus for locating improperly pos-itioned or bent rolls among a set of rolls which define a con-fined path of travel for a workpiece, particularly useful for checking a straight or curved roll-rack of a continuous-casting machine.  The apparatus may be propelled through the path de-fined by the rolls by any suitable mechanism.  For example, as applied to the roll-rack, the apparatus may be attached to the upper end of a starter bar and propelled with the bar through the rack, or the apparatus may be suspended from a hoist and pulled through the rack.  The apparatus includes a housing and means within the housing for measuring the gap between work-engaging faces of the rolls and/or, when used with a curved roll-rack, means for measuring the angular relation of adjacent bottom rolls.  The latter measurement is used in determining whether the work-engaging faces lie on arcs of the intended radii.  Bent rolls are located by observing different measure-ments when the apparatus is moved in opposite directions through the path of travel.

The cover also has an opening therethrough for allow-ing liquid sample to be inserted or withdrawn from a sample cup when such sample cup is in registry with the opening.

Abstract: A B S T R A C T          A method for measuring crack propagation in samples as a function of the number of load cycles is proposed where-in changes in the frequency response of a mechanical im-pedance of a sample which is to be tested is registered.          At a pulsation frequency, which corresponds to the resonant frequency of the sample, there is a rise in the resonance of the mechanical impedance, defined as the quotient of the speed of movement of the sample and the applied puls-ating force. Since, when a crack growth in the sample, its elastic constant decreases along with the cross-section-al area, the frequency response of the sample shifts towards lower frequences. To carry out the process of the invention it is suggested that the phase of the above mentioned im-pedance or an impedance which is dependent on it should be detected, or else to register the impedance magnitude whilst keeping the force acting on the sample or the speed of movement constant, or else to register the force or speed of movement as a function of the number of load cycles and standardised with respect to the appropriate values of momentary load or speed of movement.

Abstract: ABSTRACT         A process for oxidizing organic substrates such as ketones and ethylenically unsaturated compounds.  The substrate is contacted with aqueous hydrogen peroxide in a solution or in a two-phase liquid system, in the presence of a polymeric catalyst containing chemically bonded arsenic.  This process can lead to lactones or hydroxy acids from cyclic ketones or to esters or mixtures of alcohol and carboxylic acid from open chain ketones.          Unsaturated compounds afford epoxides and/or diols.  Preparations of certain polymers substituted by arsenic groups, particularly from polystyrene, poly(vinylpyridine) and copolymers thereof, useful as catalysts in such oxidation process, are described.  For example, polystyrene is brominated, bromine therein is replaced by lithium and the resulting lithiated polymer is converted into a polymer containing an arsenic group, such as arsono, -As(O)(O(I)2, as substituent group, by reaction with arsine triethoxide followed by oxidation and hydrolysis by aqueous hydrogen peroxide.  The aromatic polymers, polyphenylene and polymers and copolymers of vinylpyridine, can be used similarly as the catalyst.

Abstract: ABSTRACT          LOSS COMPENSATION REGULATION FOR AN INVERTER POWER SUPPLY           An inverter power supply circuit that compensates for variations in the power supply's output voltage, which variations are due to variations in output loading, is disclosed.  The input side of the circuit's DC-DC Converter-Inverter-Converter coupling transformer incorporates a compensation network having an impedance that is equivalent to the power supply's output impedance. Variations in the output loading cause corresponding proportional changes in the currents passing through the load and the compensating network.  The changing current in the compensating network on the input side of the coupling transformer generates a cor-responding changing voltage that is coupled, as a positive feedback, to the chopping transistor of the power supply to provide compensation for the variation in loading on the output side of the coupling transformer.

Abstract: ABSTRACT     A block is formed from uncured grains of refractory material.  The block is sintered to fully cure the block which, as sintered, has pores extending inwardly from the surface of the block.  The fully cured block is soaked in a first liquid to impregnate the block with the first liquid which, upon heating, forms into a material which at least partially fills the pores, and the filling material is compatible with the original refractory material of the block.          The block is then soaked in a second liquid containing very fine particles of refractory material which are deposited in the partially filled pores.  Upon heating, the very fine particles are reacted with a compound at least part of which originates with the first liquid to form a reaction product which further fills the pores.  These procedures enhance the resistance of the block to slag penetration.
