Abstract: ABSTRACT OF THE DISCLOSURE         An apparatus for separating or purifying gaseous material having more or less-adsorbable components includes a high pressure inlet chamber, a high pressure outlet chamber and a low pressure chamber.  Absorbent means retain an adsorbent capable of selectively adsorbing the more adsorbable component at a predetermined pressure level. There are also means for establishing a high pressure flow path for the gaseous material from the high pressure inlet chamber through the absorbent means to the high pressure outlet chamber.  The more adsorbable component is adsorbable by the adsorbent in the high pressure flow path.          Further means establish a low pressure desorption flow path from the adsorbent means to the low pressure chamber.  The two means for establishing flow paths are operable simultaneously to continuously separate or purify the gaseous material.  A process for separating or purifying gaseous material is also disclosed.  The gaseous material is pressurized to a pressure at which the more adsorbable component will be adsorbed by an adsorbent preferentially compared the less adsorbable component.  The pressurized gaseous material is caused to flow through and contact the absorbent to adsorb the more adsorbable component, thereby separating the more adsorbable component from the less adsorbable component.

Abstract: Abstract of the Disclosure A noise coded communications system which eliminates continuous wave (CW) interference while providing no loss or degradation of the desired signal includes the variable delay line and a linear adder coupled to the output of the front end section of a multiplexed noise coded receiver which further includes an active coherent detector comprised of a multiplier and an integrator.  The variable delay line provides a delay whose order of magnitude is substantially equal to the bit width of the multi-bit binary noise code utilized and is further varied until any CW interference signal received along with the noise coded signal is shifted in phase by 180° and inverted with respect to the input interference signal.  The inverted interference signal and the non-inverted input interference signal are summed together in the linear adder whereupon a cancellation of the interference signal occurs while providing no degradation in the desired signal.

Abstract: Abstract An improved process for producing a methane-enriched gas wherein a hydrogen-deficient carbonaceous material is treated with a hydrogen-containing pyrolysis gas at an elevated temperature and pressure to produce a product gas mixture including methane, carbon monoxide and hydrogen.  The improvement comprises passing the product gas mixture sequentially through a water-gas shift reaction zone and a gas separation zone to provide separate gas streams of methane and of a recycle gas comprising hydrogen, carbon monoxide and methane for recycle to the process.  A controlled amount of steam also is provided which when combined with the recycle gas provides a pyrolysis gas for treatment of additional hydrogen-deficient carbonaceous material.  The amount of steam used and the conditions within the water-gas shift reaction zone and gas separation zone are controlled to obtain a steady-state composition of pyrolysis gas which will comprise hydrogen as the principal constituent and a minor amount of carbon monoxide, steam and methane so that no external source of hydrogen is needed to supply the hydrogen requirements of the process.  In accordance with a particularly preferred embodiment, conditions are controlled such that there also is produced a significant quantity of benzene as a valuable coproduct.

Abstract: ABSTRACT OF THE INVENTION         A  thrust  bearing  assembly  is  provided which reduces initial axial loading on a shaft's thrust bearing in order to correspondingly reduce the required torque for rotational start-up.  The shaft's bearing runner is forced in a direction away from its associated thrust bearing during initial start-up procedures by a suitable means for imparting a force on the bearing runner in a direction away from the thrust bearing.  The force is provided by a piston and cylinder combination, in the preferred embodi-ment, which provides an axial force in a direction oppos-ing the initial  shaft  loading force.  An anti-friction guide bearing is used to transfer this force from the piston to the shaft and, in turn, to the bearing runner.

Abstract: CONTROL SYSTEM FOR WATER HEATER          WITH EXTERNAL HEAT SOURCE          ABSTRACT:      There is disclosed a control system for a water heater operatively associated with an external heat source.   The water heater includes a water storage tank and a tank heating unit.  The tank heating unit has a tank thermostat which closes when there is a demand for hot water in the tank, allowing a flow of current through the tank heating unit so as to turn it on. The tank thermostat opens when the demand has been satisfied, interrupting the current flow so as to turn off the tank heating unit.   The control system is responsive to an initial current surge through the tank heating unit for interrupting the current flow so as to maintain the tank heating unit off.   This initial current surge cleans the contacts of the tank thermostat by burning off any residue thereon.  The control system also turns on the external heat source.      The control  system is responsive to an exter-nal condition for turning off the external heat source, turning on the tank heating unit, and maintaining the external heat source off and the tank heating unit on until the tank thermostat opens.
