Abstract: RECYCLED FATTY ACID CRUDE PETROLEUM RECOVERY SYSTEM              Abstract of the Disclosure A  method of recovering crude oil  for  subsequent processing.   The  method  contemplates  the  step  of exposing   the   source  of  crude  oil  such   as   a subterranean  petroleum  reservoir  or a vessel  or  a container  of  tar  sands,  kerogen  or  the  like  to aliphatic or carboxylic acid,  preferably oleic  acid, to  produce  a solvated crude oil mixture  of  reduced viscosity,  This  mixture is saponified by reacting it with  a nucleophilic base,  preferably a hydroxide  of potassium  or  sodium,   under  pressure  whereby   to separate the solvated mixture into petroleum crude and an  acid soap which migrates to an aqueous phase.  The petroleum  crude  is separated from the aqueous  soap through   conventional   techniques.   Afterwards,   a desaponification  step  contemplates recovery  of  the aliphatic or carboxylic acid for subsequent  recycling in  the previously mentioned exposing step.  Reuse  is facilitated  by  desaponifying aqueous soap  within  a high  pressure containment vessel reacted with an acid suitable for donating a hydrated proton to the aqueous phase of the soap. This reconstituted acid is recycled for  injection into the  inputting  step.   Preferably carbonic  acid is generated for the desaponifying step by  injecting high pressure carbon dioxide within  the containment  vessel.   By-products  of  the   chemical reaction are separated and/or filtered as necessary to effectuate necessary purification sub-steps.

Abstract: ABSTRACT OF THE DISCLOSURE           A process for producing potassium phosphates by ion exchange using an Advanced Separation Device (ASD) is disclosed.  The process is carried out by supplying a phosphate salt solution, a washing solution and a potassium salt regeneration solution to respec-tive fixed feed ports in periodic fluid communication with a plurality of resin-filled chambers moving about a circular path.  Passage of the phosphate salt solu-tion through potassium loaded resin forms potassium phosphates and cation loaded resin by ion exchange. After washing out residual salts, the cation loaded resin is regenerated by adding a potassium salt which loads the resin with potassium and strips it of the cation in the form of a soluble cation salt.          By virtue of the ASD, potassium phosphate may be produced continuously and with greater efficiency than is possible with conventional ion exchange processes since the potassium salt and phosphate salt feed solutions may be fortified in an intra-stage fashion, i.e. during the course of the ion exchange or regeneration stages.  In similar fashion, the pH may be adjusted in an intra-stage fashion.

Abstract: ABSTRACT         Non-contacting sensor apparatus having two tank circuits from which an indication of the position of the moving part of the sensor is developed by measur-ing the relative resonance frequencies of the two tank circuits.  As the moving part of the sensor changes position, the relative resonance frequencies of the two tank circuits change.  The outputs of the two tank circuits are multiplexed and drive a pulse generator which develops a first series of pulses having a repe-tition rate which corresponds to the resonance frequen-cy of one of the tank circuits and a second series of pulses having a repetition rate which corresponds to the resonance frequency of the other tank circuit.  The relative times required to count the same number of pulses of each series of pulses provides an indication of the position of the moving part of the sensor.

Abstract: Abstract A closure for beverage cans including a key-shaped  sealing  tab  delineated  by  a  line  of weakening in the top panel and a lift tab overlying the  sealing  tab.   The  sealing  tab  includes  two parallel downwardly sloping grooves having vertical end walls.  A projection having a vertical wall is disposed between the grooves.  A raised, fulcrum rib is disposed adjacent the end walls of the grooves.          The lift tab includes a main portion and two down-wardly extending side arms interconnected by a pivot arm.  The side arms are disposed in the grooves.          The pivot arm is restrained for pivotal movement by the vertical wall of the projection, the end walls of the grooves  and the bottom wall of a  second projection formed in the lid.  When the lift tab is raised, it initially pivots about the axis of the pivot arm and then about the fulcrum rib.  During this latter movement, the arm portion of the lift tab applies a force to the sealing tab causing it to be partially severed and to be moved outwardly away from the pouring opening.

Abstract: ABSTRACT COMMUNICATIONS NETWORK     A network for carrying real-time (RTS) and data services comprises stations (12) on a ring (11).  Frames on the ring have a fixed boundary (15) between a real-time portion of the frame and a data portion.  A sequence of cycles is initiated by a priority station.  During a refresh cycle a bit map on the ring is marked by each station in turn to indicate which slots in the real-time portions are occupied.  Next the stations bid for slots needed for new calls.  During a third cycle information transfer for RTS calls takes place.  After these cycles, priority is passed to the next station.  The data portion may use a slotted ring or token ring data control protocol, and data transfer proceeds during RTS cycles.  In an alternative version the boundary (15') may be relocated periodically depending on the level of real-time traffic.

Abstract: ADJUSTABLE FILTER CIGARETTE            Abstract of the Disclosure A variable dilution cigarette, of the type having a filter with two relatively rotatable segments having slits in the plug wrapping and the tipping paper which rotate in and out of rotational registry to vary the dilution level, is provided which is insensitive to slight longitudinal misalignment of the slits.  An array of longitudinal depressions is formed in one segment of the filter plug centered on the slit in the plug wrapping and ending short of both ends of the filter segment containing the slit. The depressions act as a plenum allowing the longi-tudinal flow of air between the slit in the tipping paper and the slit in the plug wrapping in case of longitudinal misalignment arising during use, but do not allow circumferential air flow when the slits are intentionally deregistered by relative rotation of the filter segments.  Because the depressions do not reach the ends of the filter segment containing the slit, they do not allow any unwanted air into the filter.

Abstract: CONTROL SYSTEM FOR CONTROLLING   TRANSMISSION FLUID PRESSURE            ABSTRACT       When a pulse width modulated electrical signal  (on 12)  is employed to operate an electro-mechanical device (16),  such  as a solenoid valve, in a transmission to produce a controlled fluid pressure (in 19) whose level is proportional to the signal's duty cycle, proper operation at cold temperatures is ensured by varying the frequency of the pulse width modulated signal directly with the temperature of the transmission fluid.   By decreasing the operating frequency (Fig. 2) when the transmission fluid is cold (at which time the fluid may thicken and become heavy since its viscosity will increase), the solenoid valve will be actuated slowly enough to effect flow control through the valve and adequate regulation of the fluid pressure.
