Abstract: RADIANT HEAT BROILER ASSEMBLY            ABSTRACT         Conventional broilers, particularly those used for fast food type cooking, utilize charcoal, gas or electric grills either with direct or indirect cooking characteristics. These are relatively expensive to operate, slow in start up, and can catch fire if too much heat is applied and fat is present.  The present invention utilizes a pair of opposed gas or electric infared or radiant heaters, situated substan-tially vertically with a rack therebetween within which food to be cooked can be inserted or withdrawn from between the two heaters.  Fat and the like drip downwardly into a drip pan situated below the heaters thus reducing any tendency for the food or fat to ignite regardless of the length of time the food is left in place.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to a boat and the structural part thereof.  The object of the invention is to make available in the boat (interior) accommodation spaces in greater abundance than is normal, without having to increase the outer dimensions of boats.  The structural part of the boat is provided with a cabin and open accommodation space like the sitting well, or cock-pit in sailboats.  The structural part comprises a roof part at one end thereof and at its other end a part which is adapted to be displaced in the longitudinal direction of the boat in order to change the ratio between roofed-over space and open space.  When the structural part is moved into either of its end positions it seals against the fixed part of the boat.

Abstract: Abstract A filter bag tensioning device for use in a bag house.   The tensioning device comprises a straight lever arm adapted to be pivotally mounted in the upper reaches of a bag house and carrying, on the end of the lever arm opposite that of filter bag attachment, a semi-fixed counterweight.  The semi-fixed counterweight is prevented from rotating as its end of the lever arm moves in an ascending direction from a horizontal position but is free to rotate as its end of the lever arm moves in a descending direction from horizontal, to therebycontinuously maintain a desired design tension on an attached filter bag.  In a preferred embodiment, the lever arm can also be rotated to a vertical positionand then moved longitudinally of its pivot to substantially lower the filter bagattachment point, thereby greatly facilitating attachment and replacement of filter bags and, in a further preferred aspect, to permit these operations to be performed by a workman having both hands free.  The tensioning device is preferably mounted so as to permit maximum pivoting of the lever arm during bag cleaning operations and, accordingly, maximum deflection of and minimum stress on a filter bag attached to the tensioning device.

Abstract: Abstract:       A cod jigger is described having fish-gripping hooks which are vertically movable within the jigger body.  These fish-gripping hooks are operatively linked with normally retracted impaling hooks within the jigger body.  When a fish is caught by a fish-gripping hook and is pulled upwardly by a fishing line attached to the jigger, the resulting downward force on the fish-gripping hook causes the fish-impaling hook to swing outwardly from within the body and downwardly to impale the fish from above and prevent it from escaping from the gripping hook.

Abstract: ABSTRACT OF THE DISCLOSURE         The disclosure relates to a technique for radio frequency heating of hydrocarbonaceous earth formations in which a high power radio frequency transmitter is impedance matched to a transmission line including a plurality of conductors at least partially embedded in the formation to be heated.  The impedance matching maybe effected by a "T" network having three variable reactances.  In accordance with the teachings of the present invention, continuous variations of impedance, of the type encountered during the heating of the formation, may be matched in unambiguously defined Smith chart regions by varying two of the three reactances to minimize reflected power from the transmission line.

Abstract: SPA SYSTEM        Abstract of the Disclosure A spa system particularly adapted for installation as part of a bathtub within the home.   The various jets are fed recirculated water from a pump by individual lines from a manifold  to  assure  equal  output  regardless of  its distance from the pump.  The jets are venturi-type jets of the type to aspirate and entrain air in the output stream. The jets are connected to an adjustable air inlet system designed to allow adjustment of the air being aspirated into the water stream as well as preventing undesired water splash or spray therefrom in the event of jet blockage.            Background of the Invention The present  invention  relates to  spa  systems and, more particulaly, to spa systems of the recirculating type wherein water is drawn from a tub and recirculated through jets  to create a turbulent environment typically having water bubbles entrained as a part thereof.      Spa systems  are known  in  the  art and have gained increased  popularity  over  the  past  few years. In  the typical spa system, water is drawn through a drain in the bottom of a tub into a pump and recirculated therefrom back into  the tub  through  a  series of jet openings disposed about its periphery.   It is also very popular to include entrained bubbles within the emerging water stream from the jets.   This is accomplished in two ways.   In one type of system, the water and air are fed to the nozzle in separate pressurized lines.  This, of course, requires the use of a so-called "jet pump" to provide the pressurized air.      In the other  type of  system,  the water  is passed through the jet under pressure and the jet is constructed with a venturi to create a low pressure area therein. conduit is provided communicating between the venturi throat and the atmosphere.  As a result, air is aspirated

The apriori waveforms are gener-ated by having a process construct matched filters for these waveforms.  A FRO received waveform is used to provide an apriori representation of a TO received waveform and vice-versa.
