Abstract: ABSTRACT OF THE INVENTION          High  solids,   solvent-based   resin  composition comprises  novel  chain-extendable,  crosslinkable  urethane modified  polyhydroxy  oligomers,  crosslinking  agent  and, preferably,   catalyst(s).    The   composition   cures   at elevated temperature to provide a coating on a substrate, such as steel,  which  is  highly  resistant  to corrosion, humidity  and  solvents  and provides corrosion protection for  the  substrate.   The  novel  oligomers  can  be  the reaction  product  of  a  polyol  with  a  half-blocked diisocyanate, wherein said polyol comprises three or more hydroxy,  and the half-blocked diisocyanate comprises  the reaction   product   of   an   organic   diisocyanate   with approximately  one  molar  equivalent  of  a  monofunctional blocking agent.

Title: Pivotal paint roller
Inventor: SAMOW KURT ADDERLEY STREET NOR

Abstract: ABSTRACT    In a paint roller tool it is known that two parts, a frame usually made of 8 m/m steel rod, and a handle, are rigidly attached to each other.  The frame, of varying configurations, forms at the top a long-itudinal axis on which a cylindrical device, that holds the paint bearing sleeve, rotates.  This frame ends in a vertical shaft that is securely anchored into the handle, which at its lower end has a threaded opening to accommodate an extension handle.  The purpose of the rigid attachment of the frame to the handle is to prevent any uncontrollable movement of the frame during the operation of this tool.      In this invention the paint roller tool is fitted with a moveable frame that is set into the vertical mortise of the handle.  The shaft of the frame is attached to the handle by means of a tightenable axis running through the handle and the pivotal joint of the frame shaft.          The axis is tightened with sufficient torque at the outside of the handle to allow the setting and retention of any relative position of the frame during the operation of this tool.

Abstract: ABSTRACT            In the shucking and eviscerating  of scallops,  the yield is increased by treating the scallops prior to the heat treatment, with a sodium or potassium hydroxide solution, as this results in a more effective loosening of the contents of the scallops from  their shells and a complete separation of the valves by the subsequent heat treatment and, furthermore, in  a change in the character of the viscera, so that these can more easily be removed from the edible portion without substantial waste of the latter.

Title: Circuitry for allocating access to a demand-shared  bus

Abstract: CIRCUITRY FOR ALLOCATING ACCESS     TO A DEMAND-SHARED BUS            Abstract Circuitry is disclosed for allocating requests for demand-shared bus access among a plurality of service requesting ports.  During bus contention time, each requesting port synchronously and sequentially applies the digits of its assigned unique priority code to the bus beginning with the most significant digit.  After the application of all digits, only the requesting port having the highest code remains in contention and it seizes the bus.  Increased flexibility in port preference is provided by the use of a plurality of status flip-flops in each port for generating port parameter bits.  The generated parameter bits are applied to the bus as the most significant bits of a dynamic port priority code during contention time.  However, the selective application of a mask signal to a mask conductor during contention time causes each requesting port to ignore any parameter bits on the bus as long as the mask signal remains.  This returns control of the port preference to any unmasked parameter bits and to the assigned port priority codes.

Abstract: ABSTRACT          A method is provided for treating modified ZSM-5 type zeolite catalysts with a vapor phase organophosphorus reagent such as trimethylphosphite or dimethylmethylphosphonate in order to improve the para-selective properties of such catalysts for the conversion of aromatic materials.  The modified zeolites so treated are those which contain a minor proportion of a difficultly reducible oxide such as magnesium oxide, calcium oxide and/or phosphorus oxide.  Such catalyst compositions can be used in alkylation, transalkylation or disproportionation processes to provide alkylated aromatic product mixtures having exceptionally high concentrations of the para-dialkylbenzene isomer.

Abstract: ABSTRACT         There is described a track lifting and aligning clamping device for a railroad track.  The clamping device is mounted transversely beneath a longitudinally extending main frame of a track working machine and includes a transversely extending track aligning sub-frame which carries rail engaging wheels to support the sub-frame on the rails of a track.          Railhead contacting members are provided on either end of the sub-frame to contact the inside of each rail head and one of the contacting members is biased outwardly of the sub-frame to accommodate changes in rail head spacing.  Mounted on vertically extended guide rods at the ends of the sub-frames are rail lifting hook guide members which are arranged for vertical sliding movement on guide-rods on the sub-frame and carry, within the guide member a guide-rail  which extend transversely of the track and on which a rail hook is slidingly mounted for movement transversely of the track.  Hydraulic piston and cylinder means are connected between the top of the rail hooks and the sub-frame and act to slide the rail hooks in and out towards the outsides of the rails, transversely of the track.          Track aligning jacks are connected between the sub-frame and the main frame to move the sub-frame from side to side to cause the rail head contacting members to push against the rail heads to move the track to the left or right to align it and track lifting jacks are connected between the main frame and the guide members and act to lift the guide members with their hooks so that the hooks engage beneath the outsides of the heads of the rails or beneath the rails to lift the track to a desired height.
