Abstract: L'invention se rapporte à une méthode d'investigation géophysique en profondeur permettant l'utilisation d'un appareillage ne nécessitant pas d'installation de source très basse fréquence (T.B.F.) à proximité du forage.  un premier capteur transmet en surface un signal représentatif de la composante de champ magnétique de l'onde T.B.F. qui après amplification et filtrage est reçu à l'entrée d'un comparateur.  Un deuxième capteur, disposé dans le sondage, transmet de même un signal représentatif du champ magnétique à la profondeur z.  Les rapports d'amplitude des signaux et leur différence de phase sont fournis aux sorties du comparateur.  Ces valeurs permettent ainsi de déduire les variations des résistivités des terrains.  L'invention utilisée pour toute investigation géophysique en absence du tubage métallique permet notamment de déceler la présence de couches conductrices voisines non traversées par le forage.  L'invention se rapporte aussi à un appareil de mise en oeuvre de la méthode.

Abstract: ELECTRONIC PIANO CIRCUIT            Abstract of the Disclosure The embodiment of the invention disclosed herein is directed to an electronic musical instrument of the keyboard type used to electronically reproduce piano sounds.  The circuit has a velocity semitone circuit to vary the amplitude of the piano voice in response to the velocity of the downward movement of the key.  A master generator and dividers are provided in combination with gates for producing a fundamental square wave frequency and the second and fourth harmonics thereof, in re-sponse to the actuation of a given key on the keyboard.  One circuit arrangement includes gates for combining the fundamental frequency and the second and fourth harmonics in a predetermined time relation to produce the zero, attack, peak, and decay characteristics of a piano voice as actually produced by a piano string.  Amplitude limiting circuits are coupled to the foregoing circuit for controlling the amplitude of the harmonics in response to predetermined values so that mixing of the fundamental frequency and the second and fourth harmonics along predetermined points of the piano voice characteristics curve will more accurately reproduce electronically the sounds of a piano.  Another circuit arrangement provides a gate for rapid recovery of the piano circuit so that the keys can be actuated in rapid succession.

Abstract: ABSTRACT OF THE DISCLOSURE      The invention relates to a process for the manufacture of solid monammonium phosphate with good granulation properties suitable for use in compound fertiliser manufacture.  An improvement in product quality is obtained when between 20% and 80% of an aqueous slurry of ammonium phosphate, formed by the ammoniation of wet-process phosphoric acid, is mixed with a second acid prior to entry into a moisture disengagement unit.          This treatment precipitates some monammonium phosphate crystals which provide nuclei for further crystal growth.  After a short time delay to allow crystals to form, the remainder of the slurry is then added separately to the moisture disengagement unit.

Abstract: ABSTRACT.           This invention relates to improvements in or relating to vacuum belt filters.  It relates further to suction boxes for such filters and to a method of operation of the filters. More particularly, the invention relates to the supporting of the belt of the filter about the suction box so as to minimise drag of the belt and to minimise friction between the belt and the suction box and still seal the suction box.  This is accomplished by means of conduits that have deformable walls and are located along the edges of the suction boxes, fluid support cushions being formed in the conduits.  This is also accomplished by controlling the fluid support cushion according to the drag on the suction box, the suction pressure in the suction box and the rate of flow of fluid into the conduits to form the support cushion.

Abstract: AUGER CONTROL SYSTEM FOR A SCRAPER                      A B S T R A C T           A control system for the hydraulically powered auger of a self-loading auger scraper that has a hydraulic cushion hitch which is locked out when the scraper is loading.  A multi-position manually controlled pilot selector valve which is used to lock out the cushion hitch also initiates operation of the auger.  The control system includes a pilot operated, normally open auger control valve through which flow of a signal line for a normally open unloading relief valve goes to drain.  Moving the pilot selector valve from a first to a second position pressurizes the pilot line to close the auger control valve and thus isolate the signal line from drain, closing the unloading relief valve to isolate a pump for the auger motor from drain and cause it to power the motor.

Abstract: Abstract of the Disclosure A method for the recovery of oil from an oil-containing subterranean formation by waterflooding employing as an injection medium an aqueous solution of an anionic surfactant comprising a hydrocarbyl substituted succinimido aryl sulfonate and/or its succinamic acid derivative.  Such surfactants retain their detergency and do not precipitate in aqueous systems containing high concentrations of brine, e.g., over 20,000 ppm Ca++, over 10,000 ppm Mg++ and over 50,000 ppm Na+.  These sufactants are effective in mobilizing tertiary oil under highly saline environments and demonstrate low adsorptive losses.  When used as cosurfactants, These materials significantly improve the brine tolerance of more sensitive surfactants, such as petroleum sulfonates.  In accordance with one form of the invention, the solution of a minor amount of such surfactants with petroleum sulfonates increased the tolerance of the petroleum sulfonates four-fold with respect to sodium ions and seventy-fold with respect to calcium and magnesium ions.  According to a preferred form of the invention, the surfactants comprise the condensation products of a C10-C5, hydrocarbyl substituted succinic anhydride with either an aminobenzenedisulfonic acid or an amino naphtha-lene di- or tri-sulfonic acid.
