Abstract: CONTROL SYSTEM FOR VARIABLE PRESSURE          ONCE-THROUGH BOILER                 ABSTRACT OF THE DISCLOSURE   A system for the operation of once-through boilers which utilizes variable throttle pressure over a very wide load opera-ting range is disclosed.  The system utilizes a valving arrange-ment permitting the turbine valve (22) to be opened to a prede-termined open position, typically 70 percent of its full open position, as soon as possible during the system loading process, maintaining the turbine valve (22) in this predetermined open position while the flow of steam from the boiler is being varied by a control valve (40) and the output pressure of the boiler is varying accordingly, and then allowing the turbine valve (22) to open further from the predetermined open position when the system reaches full design pressure so as to vary the flow of steam from the boiler while the output pressure thereof is main-tained substantially constant.  In this manner, the boiler is operated at a variable output pressure over a very wide load operating range.

Abstract: APPARATUS FOR TRANSMITTING INFORMATION VIA TELEPHONE LINES     Abstract of the Disclosure Voice-band modems are used to transmit information via a loaded telephone line when a telephone connected to the line is on-hook. When the telephone is off-hook, the integrity of the line is checked by transmitting a pilot tone from the subscriber end to the central office end of the line, where the pilot tone is monitored.  Filtering of pilot tones in the central office is avoided by using two different pilot tones for originating and answered calls.  An alarm condition at the subscriber produces a shifted pilot tone frequency.  Loss or a change in frequency of the monitored pilot tone causes a telephone call on the line to be temporarily interrupted for checking the line and alarm condition.  The central office and equipment can be switched to poll consecutively a plurality of telephone lines.

Abstract: ABSTRACT OF THE DISCLOSURE           For drying organic solid materials such as, for example, brown coals, these materials are, after preheating, treated with saturated steam under a pressure of 5 to 45 bar and at a temperature of 150 to 260°C.  Prior to the subse-quent upgrading step, the water content can further be re-duced by introducing superheated steam and/or a pressure relief, whereupon immediately subsequently an upgrading treatment, particularly a gasification under pressure, a briquetting or a coal liquification, is effected with the sensible or intrinsic heat from the drying stage.  Pre-ferably the dried organic solid materials are introduced into the upgrading stage while still being under a residual pressure of the drying stage.

Abstract: TITLE:   POWDER-ACTUATED TOOL WITH POWER ADJUSTMENT          AND ANGLE-FIRE CONTROL     INVENTOR:   Jean Ollivier DOCKET NO.:   R-1191 ABSTRACT OF THE DISCLOSURE      An improved indirect-acting powder-actuated fastening tool is provided wherein the power level may be continuously varied and wherein the tool may be discharged only if the muzzle is pressed against the work surface, with the tool substantially perpendicular thereto.  A barrel and a barrel breech are adjustably screwed together and telescopically carried by a slide assembly which, in turn, is telescopically carried by the tool receiver.  The slide assembly and the barrel are operably connected for corotation, whereby rotation of the slide assembly produces a joint axial displacement, of the barrel and the slide assembly, relative to the barrel breech, to vary the initial volume.  The axial relation between the slide assembly and the barrel is thus preserved during power level adjustment and this constant relationship is utilized to effect angle-fire control by means of a firing mechanism operable solely when the slidably mounted barrel and barrel breech are urged to the battery position against the bias of a spring.

Abstract: METHOD AND APPARATUS FOR COOLING OF LIQUID FOODSTUFFS CONTAINED IN FLEXIBLE PACKAGES ABSTRACT An apparatus and method are disclosed for cooling a liquid foodstuff contained in a bouyant flexible package. The apparatus comprises a tank, a cooling liquid in said tank and a percolating means for producing turbulence within the cooling liquid. Preferably there is also supplied a means for chil-ling the cooling liquid. The percolating means is preferably a compressed gas which is introduced into the tank through a dispersion means which comprises either a perforated surface or perforated pipe. A process for cooling a liquid foodstuff contained in a bouyant flexible package is also disclosed which comprises placing the flexible package containing the liquid foodstuff into a tank containing a cool-ing liquid, percolating compressed gas into the cooling liquid thereby inducing turbulence which will cause mixing of the foodstuff within the flex-ible package insuring uniform cooling of the con-tents thereof and removing the package from the tank after it has remained in contact with the cooling liquid for a period of time sufficient to uniformly cool the foodstuff contained therein to a tempera-ture below 40°F (4°C). The process allows hot-filled, flexible packages containing liquid food-stuffs to be cooled to 40°F (4°C) within a 2 hour period thereby avoiding unacceptable bacterial growth within the food product.

Abstract: ABSTRACT OF THE DISCLOSURE            In a sausage stuffing machine if the stuffed portion of a sausage casing bursts, for example in an area which is squeezed for forming a sausage end, the meat filling continues being discharged through a filling tube but is no longer capable of pulling off the gathered-up casing from the filling tube.          With the further run of the pump, the sausage meat is spilled.          By keeping the gathered-up casing, by means of an advance mechanisms compressed into a "block" and displacing it toward the mouth of the filling tube or toward a braking ring, proportionally to the stuffing of the casing, this advance can be transmitted through a motion transformer, to a pulse generator by which, with a constant advance, pulses are delivered at constant intervals.  The pulses are received by a counter which is connected to at least the drive of a feed pump for the sausage meat.  If the casing bursts, the pulse  generator stops and no pulses reach the counter.  The absence of pulses makes the counter cause an interruption of the power supply to the pump drive.

Abstract: IMPROVED AIR RELEASE IN SEISMIC SOURCE AIR GUN            ABSTRACT OF THE DISCLOSURE      A seismic energy source air gun has a body with an air chamber formed therein that opens 360 degrees around the periphery of the body.  A sleeve-type shuttle covers the opening in a pre-fire condition.  When the air gun is fired, the shuttle moves rapidly away from the opening providing a large area for compressed air held in the chamber to escape. This very quick release maximizes the acoustic output.  The movement of the shuttle is ultimately controlled by a solenoid which, when activated, causes the shuttle to move away from the 360 degree opening and when deactivated permits the shuttle to move back into the pre-fire position over the 360 degree opening.

Abstract: Title CONTROL FOR A VARIABLE CAPACITY TEMPERATURE CONDITIONING SYSTEM                                Inventor David M. Foye Abstract A control for a variable capacity reciprocating compressor water chiller system.  A microprocessor connected to monitor return and supply fluid temperature sensors in the system is programmed to vary the compressor capacity in response to the deviation of the re-turn and supply chilled water temperatures from desired values.  The control determines these desired values as a function of predetermined full load return, supply, and reference temperature setpoints, and as a function of the relative loading of the chiller system.  The control also functions to selectively offset the chilled water temperatures in one of three control modes.  If zone temperature sensors are con-nected to the control, the offset is a function of the deviation of the weighted average zone temperature from a setpoint.  The second control mode allows offset as a function of the outdoor ambient air temperature, and the third, as a function of a temporary setpoint.
