Filed: 1979-09-11
Granted: 1981-11-10
Abstract: ROTARY POSITIVE DISPLACEMENT MACHINES                Abstract of the Disclosure The machines may function as a rotary compressor, vacuum pump, expansion engine, or the like.  Two interengaging rotors rotate within intersecting bores in a casing structure.          Two higher pressure ports are located one in each flat end wall of the casing.  One rotor opens and closes the two higher pres-sure ports so as to control the flow of air or gas through same.          The optimum number of teeth or lobes for each rotor is two.  The port controlling first rotor has lobes of small included angle so as to reduce the effect of a precompression loss.          The coacting second rotor has lobes of larger included angle so as to improve performance.

Abstract: RECOVERY OF HYDROGEN CHLORIDE IN CARBO-CHLORINATION    OF METAL OXIDES Abstract of the Disclosure In the conversion of a metal oxide to a metal chloride by reaction with chlorine and carbon monoxide wherein hydrogen chloride is produced as byproduct, the byproduct hydrogen chloride is contacted with a molten salt mixture containing the higher and lower valent chlorides of a multivalent metal and with oxygen to recover the hydrogen chloride by enriching the salt in the higher valent metal chloride. Essentially all of the chlorine values are recovered from the salt by direct contact with all or a portion of the carbon monoxide fresh feed to the metal chloride production, with such carbon monoxide stripping gaseous chlorine from the salt, as well as combining with the chlorine to produce phosgene. The carbon monoxide, chlorine and phosgene are employed in the metal chloride production.

Abstract: ABSTRACT OF THE DISCLOSURE       A method and apparatus for continuously forming a multi-ply corrugated container board from freshly laid web plies by simultaneously forming the separate plies from aqueous slurries of fibers on corresponding foraminous fabrics and dewatering each of them sufficiently to form a web ply capable of being handled in a papermaking machine as an integral web.  All of the webs are formed on a single papermaking machine, but separately.  The first web ply is laid on a traveling forming wire, such as a fourdrinier wire, and each subsequent web ply is formed in close proximity to the traveling forming wire and brought into bonding engagement seriatim with the top surface of the previously formed web ply carried on the traveling forming wire.  A typical  corrugated box board has three plies with the inner ply being corrugated.  In this invention, the intermediate web ply is doctored off either its forming roll or a pick-off roll and is allowed to contact the preceding layer in its characteristic fluted or corrugated configuration.  A spray of adhesive material is introduced onto the first ply before the corrugated ply is brought into contact and another adhesive spray is introduced onto the top surface of the corrugating medium to bond it to the top ply.     Each layer of the multi-ply corrugated board is thus formed and built into the composite product in the forming section of a single papermaking machine.  The completely formed corrugated combined board is then introduced into a suitable drying environment to finish the product.

Abstract: ABSTRACT OF THE DISCLOSURE.            To apply a measured quantity of air to the electrodes applied to a plate-like solid electrolyte body, which may be a chip on a carrier or may, itself, form the carrier, grooves, flutes, ducts, or depressions are formed in the carrier and/or a cover plate, the grooves terminating at an edge portion with access to the gas to be supplied, and having a size such that their clear height is preferably in the lower micron region, and a width, preferably under 1 mm, and particularly between 0.2 and 0.4 mm. The higher limits are applicable to apply, for example, air to a reference electrode, to apply ambient oxygen thereto; the lower limits are appropriate when operating the sensor as a polarographic sensor, in which the diffusion limited current, upon application of a bias voltage, is an analog measure of the oxygen concentration  in the gas, and the gas supply to the electrode must be suitably controlled to prevent saturation conditions.  The grooves may be formed, for example, by sandblasting or by applying insulating material in the form of posts, ridges, and the like, on the respective element, filling the space therebetween with a filler substance which, upon subsequent sintering, escapes, thus Leaving the voids forming the grooves, depressions, the like.

Abstract: ABSTRACT    This invention relates to an improved high temperature oil deodorization process for optimum bland taste and flavor maintenance.  The process comprises a selective temperature control quenching step of the hot, freshly deodorized oil.  This step comprises selectively utilizing a cooling means to quench hot, freshly deodorized oil down to a pumpable bland flavor-stable processing temperature (PBFSPT) within a selected time, preferably within a few seconds, so that the hot deodorized oil can dwell dormant in an energy efficient deodorization system. The oil can then be pumped through heat interchargers without bland oil flavor degradation or can be held at the PBFSP temperature for longer critical dormant times without flavor degradation.

Abstract: ABSTRACT OF THE DISCLOSURE           An apparatus in a receiver for data signals for correct-ly detecting a transmitted message with the aid of a local clock signal which is asynchronous in relation to the received data signal is described.  A condition hereby is that the addition or fall-away of sporadic binary characters in the message do not have any effect.  This condition is met in a redundant system, for example, in which the same message of a fixed number of bits is sent  repeatedly in sequence and the receiver accepts the message providing it detects the same message a given number of times during a given time.  According to the method, the incom-ing data signal (A) is first clocked with a phase-corrected clock signal (F) and thereafter once again with  the uncorrected clock signal (B).

Referring to anion separation, a sample including at least one highly ionized (strong ) weak anion and at least two poorly ionized (weak) cations (or vice versa) is directed with a developing reagent through an ion exchange separation column in which the weak anions, separated as a group from the strong ones, are directed to a suppressor ion exchange bed in which the developing reagent is converted to a weakly ionized form.  The strong acids are directed to an anion concentrator column which retains the anions but passes the remainder of the solution. Thereafter, the weak anions are dissolved in a developing reagent and separated on a chromatographic separation column.  The resolved anions are then directed to a detector. If the detector is of the type employing a conductivity cell, the solution is passed through a second suppressor column prior to the detector.
