Abstract: PATENT APPLICATION         of GEORGE A. ANTYPAS   for PREVENTION OF DECOMPOSITION OF           PHOSPHOROUS CONTAINING SUBSTRATES                        Abstract Loss of phosphorous from a phosphorous containing sub-strate is eliminated by maintaining a partial pressure of phosphorous in the vicinity of the substrate higher than the inherent partial pressure of phosphrous over the material of the substrate. The higher phosphorous partial pressure is obtained by positioning in the vicinity of the substrate a solution of an element such as tin or antimony containing phosphorous. The solvent metals are so chosen as to have higher solubility for phosphorous compared to the solution of phosphorous in the substrate material. The solution is exposed to the substrate in close juxtaposition but does not make physical contact with the substrate. The phosphorous vapor pressure above the solution will be proportional to the concentration of phosphorous in the solution.  Con-sequently, since the solution is selected to have a higher solubility for phosphorous compared to solutions consisting of substrate elements, the vapor pressure will be proportionally higher. Thus, the region above the exposed substrate will contain phosphorous at a vapor pressure higher than the inherent vapor pressure of the material of the substrate and phosphorous loss is eliminated.     2ner3279              - 1 -                  79-06

Abstract: ABSTRACT           Butyrolactone is produced by oxidizing an aldehyde-ether of the general formula:                                             (I) wherein R1 and R2 each, independently of the other, represent a Cl to C4 alkyl radical, and R3 and R4 each, independently of the other, represent a hydrogen atom or a Cl to C3 alkyl radical, or wherein R1 represents a Cl to C4 alkyl radical, R2 and R3 together with the carbon atoms to which they are attached form a 5-membered or 6-membered cycloaliphatic ring, and R4 represents a hydrogen atom or a Cl to C3 alkyl radical, to form an acid ether of the general formula:                                             (II) followed by deetherification, dehydration and cyclization.          Oxidation can be carried out with e.g. gaseous oxygen.          Deetherification can be accomplished by contact with an acid catalyst, whilst cyclization may occur spontaneously.  A cyclic process is described in which allyl alcohol is converted by reaction with a suitable olefin, e.g. iso-butylene, to an allyl ether of a tertiary alcohol, e.g. allyl t-butyl ether, which is then hydroformylated to form the compound of formula (I), whilst the olefin, e.g. iso-butylene, released on deetherification of the acid ether of formula (II), is recycled to the allyl ether formation step.

Abstract: McCARTHY & McCARTHY                       C A N A D A     ABSTRACT OF THE DISCLOSURE           A dual lumen cannula for use in haemodialysis by inserting the cannula into the subclavian vein of a patient to contemporaneously remove blood from the vein for treatment and to return treated blood to the vein downstream from the point of removal.  The cannula includes inner and outer lumens and blood is withdrawn through the space between the lumens.  Treated blood is returned to the inner lumen.  The outer lumen is shaped to have a curvature similar to that of the portion of the vein receiving the cannula and is sufficiently flexible to be straightened during insertion without damage or kinking.  The outer lumen has a tapered distal end portion which fits snugly about a part of the inner lumen and defines openings adjacent this end portion to withdraw blood from the vein.  Similarly the inner lumen defines openings in a portion outside the outer lumen for returning blood down-stream from the point of removal of the blood.  The inner lumen can be withdrawn between haemodialysis treatments leaving only the outer lumen in position and heparinized physiological saline solution can be injected into the outer lumen to prevent blood clotting.   If desired, the inner lumen may be left in place between treatments and both inner and outer lumens kept patent with heparinization.

Abstract: ABSTRACT OF THE DISCLOSURE     An improved guidance system for a drilling apparatus of the type used in mining operations.  The instrument package for the guidance system gathers information from roll, pitch, and a 3-position magnetometer along with a gamma counter, and converts the information to a multiplexed signal which is subsequently used to frequency modulate a pulse train.  The pulse train is then transmitted down a long cable to a receiving apparatus where the pulse train is processed by a microprocessor which demultiplexes the information, computes the roll, pitch, azimuth and gamma count and displays the computed results on appropriate visual indicators.  The operator can, from the displayed data, operate the drill in accordance with procedures already outlined in the prior art.  One of the difficulties with prior art devices has been the inability to transmit data in the presence of large background noise such as would be generated by current flowing through the area under investiga-tion covered by trolley currents, mining machine currents, etc.          The present invention overcomes the aforementioned difficulties by generating a unique pulse train which is frequency modulated, the noise, being generally one that would affect amplitude, can be clipped and eliminated.

Abstract: ABSTRACT OF THE DISCLOSURE:     A belt pressure filter comprises a gravity dewatering zone for dewatering a sludge to be dewatered as a function of the gravity and a forcible dewatering zone for forcibly dewatering the sludge by means of external pressure.  An endless filter belt is provided to travel from the gravity dewatering zone to the forcible dewatering zone.  The coagulated sludge is supplied onto the filter belt by means of the gravity dewatering zone.  Information representing the level of the sludge deposited is obtained as information concerning the dewaterbility of the coagulated sludge supplied onto the filter belt.  The traveling speed of the filter belt is operated or calculated based on the above described level information.  The optimum amount of dosage of a coagulating agent is determined based on the traveling speed of the filter belt as calculated.  As a result, the water content in a cake as dewatered is maintained low and constant, while an amount of coagulating agent most suited to the sludge characteristics at that time is dosed.

Abstract: ABSTRACT Welding apparatus and a method of producing a source of welding current. Use is made of an inverter supplied with direct current from a source to pulse a centre-tapped primary winding of a transformer at a frequency in excess of the audio range of frequencies, typically 10KHz to 20KHz. A secondary winding of the transformer has output terminals for electrical connection to an electrode and work to be welded. The operation of the inverter is controlled by means of a feedback signal derived from a winding inductively coupled to the transformer. The high operating frequency results in a significant reduction in the mass and dimensions of the welder compared to conventional elders which operate at mains frequencies.
