Abstract: PHS. 80.014 ABSTRACT:     An energy feed system for microwave ovens includes a rotatable slotted disc arranged within the oven cavity in front of a feeding aperture in a cavity wall.  The disc is essentially larger than the feeding aperture and is arranged at a small distance from the cavity wall so that a narrow space is formed between this wall and the disc, through which microwave energy can propagate radially outwardly.  The disc comprises a number of slots oriented transversally to their respec-tive radial position vectors and are dimensioned so as to serve as antenna elements for radiating energy into the interior of the oven cavity.  The disc is journalled eccentrically so as to perform simultaneously a rota-tional and a translational motion and the narrow space between the disc and the cavity wall is also utilized for guiding an air stream to impinge on vanes secured to the lower side of the disc so as to cause the disc to rotate in a predetermined direction.

Abstract: COMBINATION MICROWAVE GAS CONVECTION OVEN       Abstract A combination microwave gas convection oven having a tubular burner operating in an induced draft environment.  A blower system draws air from a combustion chamber forcing it into the heating cavity.  The slight pressure created in the combustion chamber draws in air from the heating cavity through perforations communicating therebetween completing the con-vection recirculation.  The negative pressure in the combustion chamber also causes secondary combustion air to be drawn up along the sides of the burner which is positioned adjacent to an aperture in the floor of the combustion chamber.  A plurality of top ports in the burner provides low port loading.  The structure provides good flame characteristics with low noise of combustion.

Abstract: TITLE:  FLUIDIC CAP SORTER     ABSTRACT OF THE DISCLOSURE    This invention provides a high speed cap sorter capable of producing an output of uniformly oriented caps from an input of a high speed flow of randomly oriented caps.  A fluidic jet cone sensor determines the orientation of each cap without contacting it, by means of minuscule air pressure changes.  The jet cone sensor creates a pressure signal corresponding to the orientation of the cap.  The signal is amplified to operate an air piston which allows caps having one orientation to pass directly through to an output chute, but ejects caps having another orientation into a second output chute.  One of the output chutes is curved to re-orient the caps carried therein, so that the outputs from both chutes are oriented in the same direction.

Abstract: - 15 -                Case No. 4307 ABSTRACT OF THE DISCLOSURE     A device which can determine either the velocity pressure or the velocity of a flowing gas or air stream and averages same over a predetermined period of time is disclosed.  The device utilizes a three-hole yaw probe or similar sensing means which is immersed in the stream to provide measurements of both static pressure differential and velocity pressure.  The device includes a null threshold detector (14) which permits the processing of velocity pres-sure measurements only when the static pressure differential is within a pre-set range thus insuring the proper alignment of the probe or other sensing means in the stream.  A square root extractor (20) and switching means (22) are also provided permitting the measurement and averaging of the square root of the velocity pressure measurement, i.e., velocity of the stream, by the device.  The velocity pres-sure measurements or the square root thereof are exhibited on a first digital display (28) permitting the operator to monitor the measurements as they are taken.  The measurements are subsequently averaged over a predetermined period of time by an arithmetic processor (18) and the resulting average is exhibited on a second digital display (30).

Abstract: Abstract An apparatus is provided for gathering monitored data from one or more selected wells of a number of wells and  reducing the monitored data in a real time manner to a useful form for analysis by one skilled in ground water evaluation.  The apparatus can also be used to control the discharge rate of well water to further assist in the analysis of the characteristics of the selected wells.  The apparatus is an integrated system which includes a computer, a number of inter-communicating modules, probes inserted in the wells for sensing water level, and a flow meter for use in measuring water flow rate.  A control module directly interfaces with the computer and controls the sending of control and data information to and from the computer.  A pump/flow module communicates with the control module and is used in controlling the discharge rate of water from a selected well operatively joined to a pump.  An A/D module also communicates with the control module and is used to convert data from a selected well  into digital  form for use by the computer.  Input modules interface between the probes and the A/D module to provide a compatible input to the A/D module.
