Abstract: ABSTRACT           An ultrasonic flowmeter which measures the velocity of a gas medium flowing within a conduit utilizing the time of flight principal with phase measurement approach.  A pair of ultrasonic transducers are oppositely located around the conduit at a predetermined angle to the direction of the flow. Each transducer alternates between acting as a transmitter of ultrasonic frequencies and a detector of ultrasonic frequen-cies, thus as one transducer is transmitting, the other is receiving.  In each instance, a measurement is made of the time of flight of the ultrasonic signal between the transmitter transducer and the receiver transducer and a microcomputer calculates the velocity of the gas by a known mathematical relationship utilizing the difference between the time of flight of the ultraonic signals traveling upstream and those traveling downstream.  The precise time of flight is measured by determining the phase shift or difference in phase angle between the signal at the transmitter transducer and the signal detected by the receiver transducer.  To prevent ambiguity arising when the phase angle difference exceeds 360°, the microcomputer periodically determines, by taking into account the differing gases and density thereof being measured, a zero flow phase by calculating an averaged value phase angle meas-ured in the ultrasonic signals in both the upstream and down-stream directions.  When that zero-flow phase approaches a pre-determined limit, i.e. 90° or 270°, the microcomputer alters the phase reference to take that approaching limit into account, thus shifting the phase reference to a new point at the 90° or 270° angle, the effective overall phase shift can thus exceed 360°, but the microcomputer will still accurately reflect that difference in phase angle and thus, the time of flight of the ultrasonic signals.

Abstract: ABSTRACT OF THE DISCLOSURE           Apparatus is provided for cooking or gelatinizing a material in an atomized state, so that there is obtained an easily dryable, uniform and finely-sized product.  The material which is to be cooked is injected through an atomization aperture in a nozzle assembly to form a relatively finely-sized spray.          A heating medium is also injected through an aperture in the nozzle assembly into the spray of atomized material so as to heat the material to a temperature effective to cook or gelatinize the material.  An enclosed chamber surrounds the atomization and heating medium injection apertures, and defines a vent aperture positioned to enable the heated spray of material to exit the chamber.  The arrangement is such that the elapsed time between passage of the spray of material through the chamber, i.e., from the atomization aperture and through the vent aperture, defines the cooking or gelatinization time of the material.  The apparatus disclosed is particularly useful in preparing a novel uniformly gelatinized starch product, but also has utility in connection with cooking protein or other suitable materials.

Abstract: ABSTRACT      An apparatus for severing the meat adhering on bones from these bones, in particular for poultry parts such as carcasses of chickens or turkeys, has a press comprising a press cavity into which the mass of meat and hones is intro-duced between a press piston and a counter-piston, The wall of the press cavity is, at least within the area of the counter-piston, formed of a perforated filter, The counter--piston has a closing section for a discharge opening for discharging the pressed bones from the press cavity and said closing section has a greater diameter than is the diameter of the press cavity and said counter-piston having a filter section equally formed of a perforated filter and having a smaller diameter than is the diameter of the press cavity. In closing position of the counter-piston, the filter section of the counter piston having over the length of its perforated filter the same external diameter is located at a distance from the wall, formed of a perforated filter, of the press cavity, so that an annular space is formed.          The meat having been brought to a pasty condition under the action of the press pressure passes through the holes of the perforated filter forming the wall of the press cavity and through the holes of the perforated filter forming the filter section of the counter-piston, whereas the bones are retained. These bones are discharged during a movement of the counter-piston directed away from the press piston via the thus released discharge opening.
