Title: Apparatus and method for extracting grease and smoke, and method of installing the same
Inventor: KUECHLER I
IPC: F24C15/20

Abstract: Abstract A greatly extended plenum chamber, comprising a plenum or exhaust chamber and a plenum extension connected thereto, is employed in combination with grease filters which operate by impinge-ment and by centrifugal action. Furthermore, a stream of air is directed against the upstream surfaces of the filters. The result of the combination is a surprisingly effective removal of grease and smoke from cooking fumes, with consequent minimization of grease coatings on the surfaces of the plenum chamber and of the exhaust blower connected thereto. When space does not permit vertical installation of a large extended plenum chamber, portions of such chamber may be inclined from the vertical and/or may be replaced by a plurality of smaller plenum extensions.             In an additional embodiment, the effect of a very large plenum extension is obtained by a single and much smaller plenum extension. This is achieved by (a) using a duct (to the exhaust blower) which has a diameter larger than the depth of the plenum extension, and (b) placing a relatively small air deflector below the connection between such duct and the plenum extension.             Other features of the apparatus and method include (a) a unitary construction which is substantially completed at the factory and is easily and unitarily installed at the job site by dropping it into a hole in the ceiling, and (b) an electrostatic precipitator which is sometimes employed where smog regulations are particularly stringent.

Abstract: A SUPERCONDUCTIVE SENSING CIRCUIT FOR   PROVIDING IMPROVED SIGNAL-TO-NOISE                  ABSTRACT OF THE INVENTION       A superconductive sensing circuit having improved signal-to-noise ratio is provided for use with logic circuits using logic switching devices.  The sensing circuit includes a first and second branch in parallel wherein the first branch includes a Josephson switching device.  The first branch also includes a first inductance and the second branch includes an inductance greater than or equal to the first inductance.         The Josephson device in the first branch of the sensing circuit is biased to switch into  its finite voltage state so that the gate current from the logic circuit is directed to the second sensing branch.  The Josephson device in the first branch automatically resets to  its    no voltage state so that subsequent input current is divided between the two branches inversely proportional to the inductances therein.          This subsequent current in the first branch of the sensing circuit is sensed and is indicative of the switching of one or more of the logic devices in the logic circuit.

The vehicle has front and rear quad wheel assemblies pivotally connected to a centrally disposed elongated bed frame so as to permit lateral rotation of these assemblies about the longitudinal axis of the frame.  A roll control means interconnects the quad wheel assemblies and the bed frame to proportionately control the relative angular movement.  The wheels of each quad wheel assembly are paired together by walking beam members, thus providing a suspension system having balanced load distribution between the wheels  over a wide range of terrain rough-ness conditions.  A differential drive system provides a balanced distribution of power to each wheel on both assemblies under all wheel drive conditions.  Preferably, each of these wheels is steer-able and the steering control means provides for oblique travel in conjunction with conventional steering.

Abstract: ABSTRACT OF THE DISCLOSURE           A programmable digital frequency synthesizer for providing an output signal at a selected frequency has a very low level of spurious signals in the output.  The synthesizer uses a programmable Walsh function generator having a predetermined basic period.  The generator is arranged to provide a Walsh function signal having a sequency such that the sequency divided by the basic period is equal to n times the selected frequency, n being an integer greater than one.  A scale-of-n frequency divider is connected to the Walsh function generator for counting down in response to the Walsh function signal, thereby providing a square wave at the selected frequency.  A low-pass filter is connected to the frequency divider for accepting the square wave and providing the output signal at the selected frequency by attenuating harmonics of the selected frequency.  The frequency divider serves a novel function, since it is used to "clean up" the frequency spectrum of the Walsh function signal by attenuating spurious sideband signals.  The spectrum can be cleaned up to any degree desired, since the attenuation of spurious sideband signals (as a voltage ratio) is approximately proportional to the count-down ratio n of the frequency divider.

Abstract: ABSTRACT OF THE DISCLOSURE           An interconnected web of disposable diapers containing a pair of continuous, stretched strands of elastic aligned generally parallel to the direction of web travel, is folded along its length from a substantially flat condition to produce a C-shaped, transverse cross-section by means of a conventional board and guide folder.  The C-folded web is maintained under tension during the longitudinal folding operation to keep the continuous elastic strands in a stretched condition, and the web it cut transverse to the direction of web travel without releasing the tension in either the individual diapers cut from the web or in the advancing web.  Means are provided for transversely folding the individual diapers cut from the web about their midpoints while maintaining the elastic strands associated therewith in a stretched condition and the diaper under positive control. Because the advancing web of interconnected diapers is maintained under positive control at all times, the individual diapers severed from the web are cut in register with respect to one another.  This is of critical importance in situations where the web of interconnected disposable diapers is com-prised of a plurality of discrete, interconnected diaper segments rather than a continuous web of disposable diaper material having a uniform cross-section throughout its length.
