Abstract: INVERTER CONTROL SYSTEM     Abstract of the Disclosure An inverter in a D.C. power transmission system is controlled by gate pulses which are synchronized with voltages of an A.C. system and whose interval is constant for respective arms of the inverter.  To prevent the inverter from causing a commutation failure upon occurrence of a fault in the A.C. system, a control voltage for the gate pulses is corrected by use of the magnitude of the unbalance of the phase difference between the voltages of the A.C. system.          The control voltage becomes greater, as the phase voltage or the line to line voltage falls from the rated voltage.          When the control voltage increases, the gate pulses are provided at a timing having a larger advanced control angle so as to maintain the extinction angle constant.

Abstract: ABSTRACT     Method for making a bicast article in which a solid metal preform is positioned in a mold and a molten metal is cast around portions of the preform which are exposed in the mold.  In accordance with the present invention, the exposed portion are coated prior to the casting step with a boron containing alloy which is compatible with the preform and with the metal to be cast about it, the boron containing alloy hav-ing a melting range below the melting range of either the pre-form or the cast metal.  The alloy also has a major ingredient which is the same as the major ingredient of at least one of the metals to be joined.  After solidification of the molten metal in the casting cavity, the resulting bicast article is heat treated at a temperature below the melting range of either the preform or the solidified metal to cause diffusion of boron into the preform and into the solidified metal thereby provid-ing an improved metallurgical bond.

Abstract: Abstract of the Disclosure The present invention provides a process for preparing branched chain, thermoplastic polymers having improved melt strength and die swell properties. This process comprises reacting at least one thermoplastic polymer capable of reaction with an epoxy functionality, with at least one epoxy branching agent containing at least two epoxy groups per molecule of epoxy branching agent in the molten state, in the presence of a catalytic amount of at least one catalyst. The catalyst may be selected from the group consisting of alkyl triphenyl phosphonium halide and alkenyl triphenyl phosponium halide wherein the alkyl groups contain from one to ten carbon atoms, the alkenyl groups contain from two to six carbon atoms, and the halide anion is selected from the group consisting of chloride and bromide.    The molten, thermoplastic, branched chain polymer reaction product has increased melt strength and intrinsic viscosity. When polyesters or polymers containing carboxylic acid functional groups are reacted with the epoxy branching agent, the improved polymers have a decreased number of carboxylic acid end groups. The increased melt strength polymers also have improved die swell characteristics and are useful in extrusion applications such as blow molding.

Abstract: ABSTRACT OF THE DISCLOSURE A load-supporting structure such as a table, seat, bench, shelf and the like, including at least one stationary member carrying a slidably adjustable surface which is adapted to support a load.  The adjustable load-supporting surface has channel means associated therewith in which the stationary member is slidably disposed.  A latching mechanism, pivotally carried by the load-supporting surface, is provided to frictionally engage the stationary member in the channel in order to hold the load-supporting surface in position on the stationary member.  The latching mechanism has a positive clamping mechanical advantage so that the frictional pressure exerted by the latching mechanism on the stationary member is directly proportional to the amount of weight placed on the adjustable load-supporting surface.  The latching mechanism is so constructed and arranged that upon the application of only a small amount of weight on the load-supporting surface, the frictional pressure of the latching mechanism on the stationary member is so great as to prevent disengagement of the latching mechanism and preclude movement of the adjustable load-supporting surface.

Abstract: ABSTRACT OF THE DISCLOSURE           A closure for a container of a wine or a wine-based product, of which at least a part intended to contact the product is a moulded structure of thermoplastic material having a foamed core within a liquid-impervious skin.  The structure contains sulphur dioxide and water enabling the sulphur dioxide to act as an oxygen scavenger.  Further, the present invention covers a method of forming a structure for providing at least part of a container closure for wine or a wine-based product.  The method comprises injecting through a nozzle and into a mould cavity a molten extrudate which comprises a thermoplastic material and first and second compounds which are at least partially thermally decomposed prior to passage through the nozzle so as respectively to produce sulphur dioxide and water.  The extrudate includes a foaming agent operative on the  reduction of pressure occurring when the extrudate enters the mould cavity to produce a foamed core for the structure, and causing the extrudate to cool and solidify within the mould cavity to produce a liquid-impervious skin surrounding the foamed core.

Abstract: TITLE            ELEVATING HAND TRUCK WITH POWERED TRANSPORTER                     INVENTORS                 Peter Kenneth Jeavons William Harold Hughes ABSTRACT OF THE DISCLOSURE      An elevating hand truck preserves the relative relation between load and main frame, yet allows relative migration of the wheels along the hand truck, under the influence of a prime mover, so that the hand truck can be used as an elevating hand truck for elevating loads from one elevation to another without the need to manhandle the load.  This is achieved by requiring the wheels of the hand truck to act as a moving fulcrum along but within the extent of the frame of the truck and to require the load to be fixedly engaged onto the truck frame.    With a transporter forming a 2 wheel dolly accessory, the transporter articulates with the relative positional location of the hand truck wheels so that in one position it is an inclined transporter for the truck, and its load, and in another position as a horizontal transporter therefore. In this latter position the truck and load display a reduced profile so as to allow conveyance under counters and other low barriers. The dolly accessory also folds away into the truck frame for storage when not in use.

Abstract: A B S T R A C T           Denitrosation of N-nitrosoamines is effected by reacting the nitrosoamine with a ketone or aldehyde in the presence of a strong acid, for example with acetone or acetaldehyde in the presence of hydrohcloric acid. The process has a number of advantages over the use of conventional denitrosat-ing agents such as sulfamic acid, e.g. in being less expensive and easier to operate, less exothermic and often in involving less toxic materials.  Further-more, less acid is required, thus less base for neutralising the product is required.

The crude reaction product can be purified by grinding with ice-water or ethanol and subsequent draining so as to eliminate by dissolution in such solvants the unreacted urea.    The corresponding N-methylol derivative is obtained by the reaction with formaldehyde.
