Abstract: An aerodynamic structure which when included into the design of a supersonic aircraft provides the aircraft with a higher lift/drag ratio than has been obtainable previously in supersonic aircraft design. In a preferred embodiment, the aerodynamic structure has the general shape of a modified U-channel with each of the legs of the U-channel being configured in cross section as an isosceles triangle and extending from a cross plate. The vertical apices of each triangle face each other and are separated so that shock waves originating from the leading edges of the aerodynamic structures are cancelled by expansion waves being generated from the vertical apices. At supersonic speeds lift of the aircraft is created by a pressure field generated by a shock-expansion system acting on the cross plate of the U-channel.

Abstract: A real-time magnetic digital video disk recording system has been developed for applications in on-line digital imaging systems and off-line fast access image storage and retrieval buffers. The disk recorder uses new high density recording technology and Winchester computer drive technology in a unique peripheral configuration which is fully synchronized to video system timing, provides for flexible formatting, achieves fast random access to a large video image file, and eliminates the need for complex data controllers. The recorder includes two independent actuator and head assemblies for alternately recording successive video fields on separate tracks on separate zones A and B of a disk stack. Movement of one of the actuators and head assemblies is controlled and occurs within a field time to skip tracks containing media flaws to achieve real time digital video recording.

Abstract: The method for constructing a building begins by pouring slab floors from nine inches to twelve inches less than the inside width of the finished floors of a number of buildings in a project in one phase of the project work, and, thereafter trenching and pouring footings about the floors to leave a space between the slabs and the footings in a subsequent phase of the project work. The upper elevation of the footings is set to provide the desired pitch of each building roof. Precast walls are made of standard height and length and set on the footings, the lower sections of the walls, and footings both having hooked rebars adapted to be interconnected together with the mesh reinforcing of each slab floor within the nine to twelve inch "poor strip" space provided. A pour strip or closure strip of concrete is poured over the rebars and continues the slab floor to the wall surface and downwardly to the footing.

Abstract: A girdle assembly for stud mounted rocker arms particularly adapted for use in racing engines wherein it is desired to unify the valve stud structure to prevent stud fatigue failure and adverse harmonics. The valve adjustment mechanism is provided by barrel nuts and locking studs. The barrel nut is externally threaded to accept a lower spherical seating nut on which the girdle rests in counter-bored spherical recesses which mates with the seating nuts. The bar is locked in place and the girdle assembly secured as a unitary structure by bearing washers and lock nuts engaging the upper surface of the bar and urging it into rigid contact with the seating nuts. After assembly and tightening, the girdle assembly need not be loosened or disassembled for valve adjustment, but, the latter can be carried out by adjusting the barrel nuts right through the girdle assembly while the latter is fully tightened.

It is uniquely designed to bring people together in a cozy arrangement, be it lovers, twins or friends, and can range in size from infants to adults.

Abstract: A dual loudness meter and method for simultaneously indicating the apparent loudness of composite audio program material representing peak material or of persistent material employing a first detector means responsive to peak signals for instantaneously indicating the same as a singly actuated LED indicator in an array thereof displayed in accordance with the peak strength of the signal, a second detector for detecting the persistence of the signal and displaying the same as a bar graph on said LED display, the materials being colinearlly displayed and having dual upper extreme warning/operating indicator means separated by about 12 to 14 dB so that the meter is read as requiring adjustment of the associated recording or broadcast facilities to avoid having either of said programming indicator displays reading consistently in either warning/operating zone. Specific circuits and time constants of response and decay are given as appropriate to the simultaneous reading, dual meter system disclosed.

Abstract: A multiple chamber fly trap contains approximately concentric screens defining a region within the inner screen into which the flies enter for the bait, an annular second region between the screens into which the flies enter to escape to the light, and a third region below the second region into which the flies drop after exhaustion. A plurality of openings between the consecutive regions allow passage of the flies from the first to the second to the third and into a removable collector which is preferably a disposable bag.
