Abstract: ABSTRACT    A data processing system having a flexible internal structure, protected from and effectively invisible to users, with multilevel control and stack mechanisms and capability of performing multiple, concurrent operations, and providing a flexible, simplified interface to users. The system is internally comprised of a plurality of separate. independent processors, each having a separate microinstruction control and at least one separate. independent port to a central communications and memory node.  The communications and memory node is an independent processor having separate. independent microinstruction control and comprised of a plurality of independently operating, microinstruction controlled processors capable of performing multiple, concurrent memory and communications operations.  Addressing mechanisms allow permanent. unique identification of information and an extremely large address space accessible and common to all such systems.  Addresses are independent of system physical configuration. Information is identified to bit granular level and to information type and format.  Protection mechanisms provide variable access rights associated with individual bodies of information.  User language instructions are transformed into dialect coded, uniform. intermediate level instructions to provide equal facility of execution for all user languages.  Operands are referred to by uniform format names which are transformed, by internal mechanisms transparent to users, into addresses.

Abstract: "ROCK WINDROWER" ABSTRACT OF THE DISCLOSURE          A windrower drum is journalled for rotation on the lower ends of and between a pair of arms each of which forms part of a transverse support member supported by the chassis.  An arm extends upwardly from the transverse sup-port and forms a crank arm with the aforementioned arms supporting the windrower drum.  A floating cylinder lug is pivoted intermediate the ends thereof to said chassis and a piston and cylinder assembly extends between the distal ends of said crank arm and said floating cylinder lug.  The weight of the drum and arms engages the drum with the ground with the depth of penetration being controlled by the effective length of the piston and cylinder assem-bly which acts as a rigid link when set.  The drum, support arms, floating cylinder lug and crank arm all act as one unit so that the drum can elevate if an obstruction is en-countered and returned by gravity to the preset position after passing the obstruction thereby eliminating any counterbalance springs and the like.  The drum can be locked in a transport position or can be locked for frame levelling purposes.

Abstract: TITLE OFF-AXIS ELECTRON GUN     INVENTORS Ronald M. Hutcheon ABSTRACT OF THE DISCLOSURE The purpose of the off-axis electron gun is to generate a beam of electrons and to deflect the beam onto the axis of a device which utilizes the beam.  The off-axis electron gun includes an arcuate wire electron emitting source, a non-intercepting azimuthally asymmetric elec-trode located at and around the electron source, and an anode plate with a beam exit hole.  The non-intercepting electrode has an arcuate slot subtending a predetermined angle at a predetermined radius from the beam axis.  The arcuate wire electron source is mounted within the slot in the electrode, but is electrically isolated from the electrode.  The elec-trode is asymmetric in shape such that when selected voltages are applied between the wire source, the non-intercepting electrode and the anode, an electric field is produced which directs the electrons towards the axis and simultaneously focusses the beam and deflects it onto the axis.

Abstract: REHEATING OF PREFORMS WITH RADIO FREQUENCY ENERGY           ABSTRACT OF THE DISCLOSURE         This relates to the discovery that when polymer preforms are reheated in the forming of polymer bottles by blow molding techniques, if the reheating is effected by the use of RF energy, there will be a heating of the interior wall portion of the preform to a higher tempera-ture than that of the exterior wall portion, with the result that, due to the requirement of greater stretching of the interior preform wall portion, a more effective stretching of the heated preform during the blow molding thereof occurs with a highly beneficial result including a more controlled stretching of the polymer and a material reduction of the recently discovered chain scission and laminating effect which exists in like bottles formed of like preforms using present commercial heating methods. The differential temperature gradient resulting from RF heating has particularly beneficial results when the polymer is PET.

Abstract: SPECIFICATION          "Improvements in or Relating to Apparatus for Signalling within a Borehole while Drilling"     ABSTRACT OF THE DISCLOSURE           A down-hole signal transmitter for a mud pulse telemetry system comprises a flow constrictor defining a throttle orifice for the mud flow, a throttling member displaceable to vary the throughflow cross-section of the throttle orifice, and a pump for displacing the throttling member against the mud flow in order to modulate the mud flow.  The displacement of the throttling member is con-trolled by a hydraulic amplifier, comprising a main pressure relief valve and a subsidiary control valve, and a solenoid to which the output signal of a measuring in-strument is supplied.  When the main valve is closed, the pump displaces a ram coupled to the throttling member upwardly. However, when the signal supplied to the solenoid is such as to magnetically attract an armature, the control valve is opened to conduct a small flow of oil between the pump input and the pump output, and this in turn causes the main valve to open thus conducting a much larger flow of oil from the pump input to the pump output and allowing the throttling member to be displaced downwardly by the pressure of the mud flow.  The power consumption required to modulate the mud flow with this arrangement is very low, and this is easily met by a down-hole electrical generator.
