Abstract: Abstract of the Disclosure Precooked sliced bacon is produced which is generally comparable in nature and quality to conventional precooked sliced bacon but which has a reduced nitrite content as compared to conventional precooked sliced bacon.  At the present time under Federal regulations, it is permissible to introduce up to approximately 200 ppm of nitrite (calculated as sodium nitrite) when curing bacon bellies.  By the present invention, this concentration of nitrite can be reduced to a range from about 5 ppm to about 120 ppm without producing unacceptable changes in the bacon provided that, after smoking, the bacon is sliced and then precooked thereby reducing its water content to a level which does not support growth of Clostridium botulinum.

Abstract: ABSTRACT OF THE DISCLOSURE             A compensating circuit has a frequency response curve into which can be introduced elevations or depressions of selected breadth at selected frequencies. The compensating circuit includes a plurality of tunable circuit stages associated with different frequency ranges. Each tunable circuit stage includes a resistor and a inductor connected in series with each other and to the rotor terminal of a differential capacitor having two stator terminals. The first stator terminals of the differential capacitors are con-nected to the first winding or windings of one or more differential transformers, while the second stator terminals of the differential capacitors are connected to the second winding or windings of the one or more differential transformers. The voltage induced across the one or more differential transformers is then employed to sup-plement the voltage which is being transmitted to the output re-sistor, of the compensating circuit by the input transformer of the compensating circuit.

Abstract: ABSTRACT OF THE DISCLOSURE           A fireplace is designed for installation in an enclosure such as a house.  It includes a firebox for confining the combus-tion region.  Of course, it has an exhaust outlet.  A heat-exchange system is in heat-transfer relationship with the firebox.  An air supply feeds air from outside the enclosure.  A circulation system conducts air through the heat-exhange system and in communi-cation with the enclosure.  A control arrangement governs the conveyance of air from the supply to both the firebox and the heat-exchange system.  A thermostat system within the enclosure operates the control means in response to temperature changes.          Outside air is utilized both to control the degree of combustion and in the operation of the circulation system that heats the enclosure.  A hollow grate system enhances efficiency.

Abstract: ABSTRACT OF THE DISCLOSURE:           A marine vessel is provided with a closed tank for gravity separation of immiscible mixtures of water and other fluid lighter than water, such as oil.  A manifold extends around the upper inner periphery of the tank and discharges upwardly into the tank through a multiplicity of ports, the tank preferably being completely filled with water and the other liquid.  Separated water is withdrawn from the bottom of the tank through a plurality of coalescing filters having large exposed coalescer screens.  Hoods over the coalescers direct flow thereto to ensure uniform distribution of water and oil globules over their surfaces and direct coalesced oil toward the upper region of the tank in a concentrated stream.  A pump withdraws the water from the tank and discharges it, for example, into the ambient water. Flow produced by the pump can be reversed for backwashing the coalescers.  A detector and water flow control in the tank senses the level of the interface between separated water and lighter liquid (oil) and when that interface reaches a predetermined lower level, flow of water out of the separator is cyclically reversed while lighter liquid is discharged from the top of the tank until the interface rises to a desired upper level.

Abstract: OVERLOAD PROTECTION APPARATUS FOR HOISTING MACHINE          Abstract of the Disclosure An overload protection apparatus for a hoisting machine such as a rope hoist or chain block employs a gear mechanism in the reduction gear train of the machine.  Such gear mechanism is composed of outer and inner gear units be-tween which torque is transmitted by means of springs there-between.  The springs are compressed upon transmission of an excessively large torque, i.e. in case of an overload.  This allows relative rotational movement between the outer and the inner gear units.  This relative rotational movement is then converted into an axial movement.  A detecting switch, upon detecting this axial movement, open an electric circuit to stop the lifting operation.
