Abstract: Abstract of the Disclosure A single-ended recuperative radiant tube assembly for increasing the efficiency of a combus-tion furnace system by using less fuel input per heat output than conventional systems.  The single-ended recuperative radiant tube assembly has inner and outer recuperator tube assemblies positioned in a counterflow arrangement within a radiant tube assembly.  Hot exhaust gases emitted from a burner within the single-ended radiant tube assembly are directed through a flame tube to an annular exhaust chamber located between the outer recuperator tube and radiant tube assemblies.  Ambient air flowing towards the burner in an air chamber between the inner and outer recuperator tube assemblies is heated by the exhaust gases in the annular exhaust chamber.

Abstract: ABSTRACT OF THE DISCLOSURE         A   digital  pulse   compression  radar   system   with interrupted, phase  coded, high duty  ratio  transmissions  which allow contiguous range resolution cells to be established in cov-erage  space and  provide  adequate  airframe impulse  excitation recovery time to render high  duty ratio, phase coded, radar fea-sible for airborne applications.          Each pulse is subdivided into a predetermined number of subpulses or  bits,  which  are phase  coded  with  (in-phase  or out-of-phase) reference to a master oscillator.  In the preferred embodiment, the code  is built up from a  PRN code staggered over 2n-1 pulses, each containing m resolution elements, where n is an arbitrary number  designating the degree  of the code and where m is an  arbitrary  number or is  equal to  the number  of bits per pulse.  The correlation properties of the code are such that when all bits of  the returned  pulses representing  a word align with the delayed transmitted word, all bits add.  When the bits do not align precisely, the  bits generally  cancel each other.  Because of  this,  partial pulse  overlaps  do not  produce  a noticeable-effect and  ambiguity of  the range  is no longer  limited by the time separation of adjacent pulses.

Abstract: ABSTRACT OF THE DISCLOSURE         A self propelled forklift vehicle having a frame formed by two spaced parallel longitudinal frame members and a rear transverse frame member.  The fork carriage is movable forwardly and rearwardly on the longitudinal frame members, along the path of the machine, and carries a fork tower and forks.  The forks can be forced below the vehicle to raise the vehicle up beneath the rear of a trailer for trans-port.  The vehicle's rear wheels, which steer and drive the vehicle, are closely spaced and tiltable from side to side to allow for rough terrain, with the operator seat and motor on opposite sides thereof to balance each other.  A manually operated split pulley drive allows creeping of the vehicle at a closely controlled low speed.  The fork tines include erectable rollers to support part of the vehicle weight when the forks carry a forwardly extended load, to prevent tipping.  A front gate causes discharge of the contents of a pallet onto the ground when the fork carriage is retracted.  An automatic centering mechanism returns the rear driving wheels to either front driving or rear driving position as selected by the operator.

Abstract: ABSTRACT OF THE DISCLOSURE          The flow of hydraulic fluid to the pump of a pump jack and consequently the stroke of the polished rod is con-trolled by a pair of magnetic proximity limit switches mounted on the frame of the pump jack, and a magnet mounted on the polished rod.  Closing of one switch by the magnet actuates a relay, which connects a battery to a solenoid for opening a valve through which hydraulic fluid is fed to one side of a double acting control cylinder.  The control cylinder operates a pump, which feeds hydraulic fluid to one of a pair of oper-ating cylinders which move the walking beam, horsehead and polished rod.  Closing of the other switch reverses the flow of hydraulic fluid to the control cylinder which causes the pump to feed hydraulic fluid to the other operating cylinder while taking oil from the first operating cylinder.

Abstract: ABSTRACT OF THE DISCLOSURE    A metal-oxide-silicon (MOS) field effect transistor (FET) regenerative differential comparator circuit particularly suited for use in sigma-delta modulation apparatus.  The circuit includes two differential ampli-fier stages followed by a latching amplifier stage.  A regenerative latching section of two cross-connected latching FET's is connected to the latching amplifier stage.  Each of the latching FET's is connected in series with a separate switching FET.  A strobe pulse turns on the two switching FET's enabling the latching FET's. Depending on the relative polarity of the differential voltage produced by the latching amplifier stage, regenerative action drives one of the two latching FET's into heavy conduction thereby producing an appropriate digital output.  The first two differential amplifier stages remain enabled during the regenerative action permitting high speed operation.
