Abstract: Abstract of Disclosure An apparatus for repeatably forming shaped dough bodies having a filling.  A generally cylindrical filling forming mechanism, in communication with a pressurized source of filling material, is contained within and is surrounded by a generally cylindrical dough forming mechanism in communication with a pressurized source of dough.  The filling forming mechanism includes an inner chamber which receives the filling material, means defining a filling material transporting channel extending around the circumference of the filling forming mechanism which channel can be selectively opened to permit the filling material to flow out of it, and a generally cylindrical shell member which is mounted to obstruct the filling material transporting channel and which includes a plurality of shaped filling forming orifices in its periphery.  The dough forming mechanism has dough forming orifices in its periphery which are aligned with corresponding filling forming orifices in the shell member of the filling forming mechanism.  Means are provided for opening and closing the filling material transporting channel and dough forming orifices in timed relationship to produce the shaped, filled bodies.

Abstract: ABSTRACT OF THE DISCLOSURE            The invention is concerned with a method of fluidised bed processing of phosphogypsum into sulphur dioxide and calcium oxide, which comprises (a) preliminary drying humid phosphogypsum; (b) mixing the preliminary dried phosphogypsum with 0.01 to 6% by weight of granulation-binding additives, in aqueous solution, and optionally with 1 to 15% by weight of carbon-containing materials and with 2 to 25% by weight of sulphur-containing raw materials, the weight percentages being based on the weight of the phosphogysum, the binding additi-ves being selected from the group consisting of carbamide, carboxymethyl cellulose, ammonium bitrate, calcium nitrate, polyethylene oxide and the distillation fluids from soda production; (c) granulating the mixture; (d) subjecting the granules to a thermal treatment at 100-700°C for 10-90 minutes;           (e) screening the thermally treated granukes to isolate a fraction having 1-3 mm size range; and (f) subjecting the iso-lated fraction to a thermal dissociation in fluidised bed, in the presence of propane-butane gas mixture as a reducer.           The method of the invention enables one to carry out the ther-mal dissociation of the phosphogysum granules at temperatures as high as 1300°C, without the occurrence of any sintering of the charge.  The possibility of working at such high tempera-tures allows to significantly increase the degree and the rate of dissociation of the phosphogypsum into sulphur dioxide and calcium oxide.

Abstract: ABSTRACT OF THE DISCLOSURE                A security locking device for dead-bolt door locks which is distinguished by a shroud that encompasses and grips the dead-bolt actuator at the inside of the door, and is rotatably mounted in a base secured to the inner face of the door, with a handle portion on the shroud exposed to enable the shroud - and hence the dead-bolt actuator - to be manually turned.  A spring biased security bolt slidably mounted in the base engages a cylindrical side surface of the shroud and snaps into a keeper recess in that surface when the shroud is turned to the position at which the dead-bolt is in its projected door-locking position.           A manually rotatable cylinder with an eccentric lug at its inner end to engage one or the other of a pair of opposing shoulders on the security bolt is mounted in the base and operable from inside the door to enable retraction of the security bolt and to select-ively hold the security bolt in either its projected operative position or its retracted inoperative position.  A similar security bolt control is provided at the outside of the door, but in this case it is in the form of a key controlled lock cylinder which, in its locked position, holds the security bolt in its projected oper-ative position to prevent unauthorized opening of the door, even from the inside, and when turned from its locked position, retracts the security bolt to free the adjacent exterior dead-bolt actuator for the rotation needed to retract the dead-bolt.

Abstract: ABSTRACT OF THE DISCLOSURE          METHOD FOR INTERPRETATION OF SEISMIC RECORDS TO YIELD INDICATIONS OF GASEOUS HYDROCARBONS The present invention indicates that gas-containing strata of an earth formation have low Poisson's ratios and that the acoustic contrast with the overburden rock has a surprising effect as a function of the angle of incidence on a seismic wave associated with an array of sources and detectors:  viz., a significant -- and progressive -- change in P-wave reflection coefficient as a function of the angle of incidence occurs.          Thus, differentiating between high-intensity amplitude anomalies of nongas- and gas-containing media is simplified:  progressive change in amplitude intensity of resulting traces generated by the field array as a function of offset between each source-detector pair, is associated with the last-mentioned medium only.

Abstract: SPRAYING APPARATUS                 Abstract of the Disclosure A spraying apparatus utilizes pressurized gas to spray liquid contained in a large replaceable or refillable cartridge.          The cartridge is positioned within a casing which provides a pressure chamber, and a source of pressurized gas is attached to the casing to pressurize the chamber.  The top of the cartridge communicates with the chamber so that the liquid is also pressur-ized.  A tube extends from above the level of the liquid in the cartridge to the bottom of the cartridge and is attached to a valve.  An opening is provided in the tube adjacent to the bottom of the cartridge, and the diameter of the tube is reduced above the opening to restrict the flow of gas through the tube and to create a pressure differential in the tube.  When the valve is open, pressurized gas flows through the tube, and, since the pres-sure of the gas inside the tube at the opening is less than the pressure of the fluid, liquid flows through the opening mixes with the gas within the tube, and flows through the valve.
