Abstract: ABSTRACT           Extended control word decode circuitry in-creases the number of simultaneous functions performed during execution of a control word in the central processing unit (CPU) of a computer system. A first field of a control word is decoded into 2n decodes for testing or specifying a first set of CPU conditions. A second field in the control word is decoded into 2m - X decodes for testing or specifying a second set of CPU conditions. The X decodes, which together with the 2n decodes of the first field test or specify multiples or pairs of a third set of CPU conditions and inhibit the 2n decodes from testing or specifying said first set of CPU conditions.

Abstract: ABSTRACT OF THE INVENTION           A rubber-reinforced polymer of a monovinylidene aromatic compound, e.g., styrene, having rubber of two different particle sizes distributed through the polymer matrix and exhibiting a desirable balance of gloss and toughness properties is continuously prepared using mass polymerization techniques.  Specifically, the rubber-reinforced polymer is prepared by polymerizing a solution of the rubber and monovinylidene aromatic compound in the presence of a graft promoting initiator, e.g., dibenzoyl peroxide, and at conditions sufficient to form a dispersion comprising a continuous phase of polymer having discrete, rubber particles of a particle size from 0.5 to 1.5 micron dispersed therethrough. Subsequently, additional amounts of rubber are added to the polymerization mixture and polymerization continued at conditions such that the newly added rubber is dispersed throughout the continuous polymer phase as discrete particles having a particle size from 4 to 10 microns.  The polymerization is completed and the rubber subsequently crosslinked.

Abstract: CONTROL FOR AN ELECTROSTATIC TREATER Abstract of the Invention An automatic voltage control system controls the voltage delivered to the primary winding (12) of a step-up transformer (10) and hence the power delivered to a dehydrator (40) so as to prevent the step-up transformer (10) from exceeding rated power when a current limit occurs.  The automatic voltage control system controls the voltage applied to the primary winding (12) so as to maximize the voltage applied to the grid elements (38) of the dehydrator (40).  Upon encountering a current limiting condition, the automatic voltage control system reduces to zero the voltage applied to the primary winding (12) and hence the power applied to grid elements (38) of the dehydrator (40) to dissipate the cause of the current limiting condition.  The voltage is reapplied to primary winding 12 at a voltage level below where the current limit occurred.  The voltage is then increased to maximize the voltage applied to the grid elements (38) of the dehydrator (40).  Upon encountering a voltage limit, the voltage is maintained at a constant level until either an arc or current limit are encountered whereupon the control cycle is repeated.

Abstract: IN SITU RECOVERY PROCESS FOR HEAVY OIL SANDS                   (D# 51,500 TexEx-43-F) ABSTRACT OF THE DISCLOSURE    Bitumen is recovered from a subterranean formation of heavy oil sands traversed by at least one injection well and at least one associated production well in fluid communication with each injection well.  Air in admixture with a heating fluid selected from the group consisting of low quality steam, hot water, or mixtures thereof, and an alkalinity agent are injected into the formation by way of each injection well.  The subterranean heavy oil sands are thereby raised to a temperature in the range of about 200 to 350°F.  A portion of the bitumen at reduced viscosity is oxidized without burning to produce additional petroleum acids which are neutralized to form emulsifying agents.          The condensed steam and/or hot water contacting the bitumen form with it a bitumen-water emulsion.  By pressure from the injected mixture of air and heating fluid, the resulting bitumen-water emulsion is then recovered from each production well.  Demulsification takes place at the surface and bitumen, hot water, and sand are separated.          Increased oil recovery efficiency may be obtained by pressure controlled cycles.

At the intersection, reduced weight segments (44, not shown) of the rods pass, respectively, over and under a centrally located septum (36).  The crossover segment of the line 26 passes between the septum and a cover (not shown) to provide the structure of a coaxial line between the cover and the septum.          Matching structures in the form of a miter at the end of each center conductor reduce reflection at the junction of the segment at the septum with the balance of the transmission line.  The foregoing segments are approximately one-quarter wavelength of the microwave frequency.

Abstract: ABSTRACT OF THE DISCLOSURE            Part of a wooden casing, in particular in the form of a case for a telephone apparatus, is manufactured as follows. A piece of timber is dried for the duration of a drying period inside an oven (2) until the timber is just above its cell collapse limit, and at the end of the drying period the temperature is adjusted in such a way as to cause the resin in the timber to flow out and seal the pith fibres of the wood with the intention of preventing the wood from re-absorbing moisture. From the timber (5) dried in this way is taken a blank which is to form the case. The blank is then worked into the final shape of the case. Any weak points is the casing are reinforced with a reinforcing material in the form of wood or some other material. The pores of the wood are then sealed with varnish.
