Abstract: A device for rotatably supporting a drum or reel of the type on which cable is wound. The vertical flanges of respective angle members are spaced apart to receive therebetween the circular end flange of the cable drum. The drum flange is supported on roller bearings mounted between the angle members. An arcuate cutout is formed in the vertical flange of one angle in order to accommodate the outer layer of cable when the drum is full or nearly full. The invention also provides a toggle type mechanism used to add an undamaged circular flange onto the damaged flange of a cable drum. The toggle mechanism extends from the undamaged flange and may be expanded after having been passed through the central opening of the damaged flange. Expansion of the connector rigidly holds the undamaged flange on the end of the drum, with a spacer disc acting to maintain the flanges apart from one another.

Abstract: A single crystal controlled oscillator provides clock pulses that are used to drive both the decoder shift register and the encoder shift register of an ATC transponder. An input pulse of the interrogation signal from a ground station is shifted down in the decoder shift register and is time correlated with a subsequent pulse of the input signal to verify the validity of the interrogation. A valid interrogation signal triggers gate logic circuitry which loads data into the encoder shift register. The clock pulses from the oscillator are processed to the appropriate frequency for driving the encoder shift register, which outputs serial data for transmission as a coded reply signal responsive to the interrogation signal. The decoder shift register and cooperating edge trigger coincidence gate circuitry suppress side lobe interrogation signal and inhibit operation of the transponder when same are present.

Abstract: A command bar gives pitch and roll commands to an aircraft pilot. The command bar is carried on a magnet assembly which is supported to pivot on a pair of perpendicular edges that correspond to the pitch and roll axes. A permanent bar magnet included in the assembly has its opposite ends received within bobbins on which coils are wound. The coils are arranged in a plurality of separate tiers located above and below the ends of the magnet. Fields are generated by the coils to selectively deflect the magnet in a manner to effect pitch and roll movement of the command bar.

Abstract: A monument marker is formed with a clear plastic outer laminate and an inner concrete core. The space between the outer laminate and the core is filled with urethane foam to accommodate expansion and contraction of the concrete core. The outer laminate is formed in either one or two pieces by casting or blow molding. After curing of the outer laminate, the concrete core is positioned centrally of the laminate shell in spaced relationship to the shell walls. The space between the core and the walls is then filled with an expandable liquid such as urethane foam. As the liquid expands it will completely fill the space in the shell and provide an area of rigid yet yieldable material capable of responding to contraction and expansion of the concrete. Indicia presenting a name or message may be secured inside the clear plastic laminate before filling with the expandable liquid. The expanded material is trimmed to present a smooth base and a sheet of plastic may be secured to seal the shell.

Abstract: An automatic data input/output system has combined card reading and recording device features which permit a pilot to totally utilize same as part of an aircraft navigation system. A small light weight drive system is incorporated within the device to move the magnetic card with respect to the read-write heads.The operational modes of the system include a MONITOR MODE, a RECORD MODE, an ENTER MODE, and an ERROR MODE. This permits a pilot to encode or record navigational data on a magnetic card or read the data from the card and automatically input same to a device for assisting in the navigation of the aircraft. The ERROR MODE provides a means for checking the data as read from the card to insure the accuracy of same before it can be used by the navigational device.

Abstract: A machine for successively forming open topped bags from a continuous roll of tubular, gusseted packaging material and for sealing the tops of the bags after they have been filled with objects. A pivotal heat sealing member is driven into engagement with the packaging material to seal the top of one bag, effect a series of perforations below the seal, seal the bottom of the next succeeding bag, and sever the packaging material between the two seals. A cutting member mounted on the rear side of the machine is simultaneously pivoted to cut substantially through the front web and the two folded gussets of the packaging material to form a three-sided opening in the top of the second bag. A roller then advances the sealed bottom portion of the second bag into a support tray with the open top portion in a convenient position for receiving objects. A single motor drives the working components of the machine.

Abstract: A self-tapping applicator head for chemical injection treatment of trees comprises a socket and a tapered integrally formed and exteriorly threaded shank portion. A centrally-defined hole or passageway extends substantially the length of the shank portion, connecting the tip of the shank with the socket. The tip portion of the shank has a plurality of output orifices defined therein and oriented transversely in communicating relationship with respect to the central passageway. The socket is provided with a centrally defined interiorly threaded hole, which has a diameter substantially greater than the diameter of the shank passageway, and which matingly receives the male fitting at one end of a separate, pressurized hose line. Pressurized chemicals delivered to the socket fitting are forced through the nozzle shank output orifices into the sapwood portion of the tree with the sealing effect of the tapered nozzle preventing leakage therearound.

Abstract: A machine for stripping the meat of precooked poultry legs from the connected leg and thigh bones. The legs are loaded on a horizontal auger conveyor and conveyed to a vertical chain conveyor which carries the legs longitudinally upwardly through a meat stripping mechanism. The stripping mechanism includes two horizontal discs rotating with their closely spaced peripheral stripping edges in opposition to engagingly strip the meat downwardly from the upwardly moving legs. A third horizontal disc rotating with its peripheral edge behind and sightly below the two opposed stripping edges assists in the stripping operation. The opposed stripping edges of the discs include cooperating recesses through which the knuckle joints and enlarged end joints of the legs freely pass. After being stripped, the bones are ejected from the chain conveyor by a rotating ejection rod.

Abstract: A slot diffuser is utilized to counteract large heat losses through a wall or window by producing a vertical blanket or curtain of air adjacent the wall or window. An elongate housing defines a plenum chamber delivering air to a uniquely constructed convergent-divergent diffuser slot. High velocity air exits from the diffuser slot and is rapidly intermixed with the induced cold air from the wall or window. The rapid mixing, resulting from the high discharge velocity, permits very hot air to be introduced into the room, yielding a high induction ratio so that a small volume of air counteracts a high rate of heat leakage. The specially shaped diffuser slot performs relatively noiselessly while permitting high velocity air to flow therethrough.

Abstract: A fishing lure comprises a molded plastic body in which a plurality of lead pellets are uniformly dispersed to weight the lure and give it a visibly distinct, speckled exterior appearance. The lure has a tail portion comprised of distinctly colored feathers which are received within a generally tubular orifice at the rear of the lure body.The method of manufacturing the lure comprises the steps of correctly aligning a hook in an appropriate mold, injecting a thermosetting PVC plastic into the cavity interiorly of the mold, adding lead pellets to the plastic before it hardens so that the pellets will become distributed therein, inserting a core pin at the rear of the lure, appropriately heating the lure to harden the plastic, removing the core pin after the plastic has hardened, thereby creating a tubular orifice at the rear of the lure, and inserting feathers into the orifice and gluing them to the lure, thereby providing a tail.

Abstract: A compact, electrically powered can opener with power pierce has a compound piercing lever comprised of a pivotally mounted hand lever and an interconnected, removable cutter mounting plate. The cutter mounting plate is removably and pivotally connected to the frame by a pin member latching combination. A first pin member extends rearwardly from the cutter mounting plate and is received in a suitable aperture in the can opener frame to pivotally attach the cutter mounting plate thereto. A cooperating latching combination, comprised of a latch arrangement located between the cutter mounting plate and the can opener frame and a slotted frame aperture which cooperates with a second, rearwardly extending cutter mounting plate pin, firmly maintains the cutter mounting plate in correct alignment with respect to the frame as the cutter mounting plate pivots, precluding axial separation therebetween throughout a major portion of the pivot arc.

The rollers are rotatably connected to framework and are conveniently arranged in two separate paths, one path for the left wheels and one path for the right wheels. Guide rollers are also connected to the framework but have an axis of rotation elevated with reference to the vehicle support rollers.

Abstract: An attachment for installation on the bucket of a front end loader includes a platform which alternately functions as a rigid extension of the bottom or top of the bucket. The platform is pivotally carried between the outer ends of a pair of parallel arms which are pivoted at their other ends to the opposite sides of the bucket. The platform seats firmly on the blade which extends from the bottom of the bucket and may be moved upwardly to a position wherein it may be secured on top of the bucket. A pair of stop plates control the pivoting of the platform as the arms are raised or lowered.

Abstract: A digital display doppler radar unit has a moving mode and a stationary mode. The incoming doppler signal, which in the moving mode, represents both speed of the radar platform and speed of an approaching target vehicle, is separated into two signal components by selective filtering. One component represents the sum of the ground speeds for the radar platform and approaching vehicles. A time base is generated by a crystal control means and the time base is utilized for correlating the received doppler signals, indicative of speed, with the time base. Each doppler signal component is converted to binary coded decimal (BCD) information and a digital counter counts the cycles of each reeived doppler signal and compares the count with an amount previously stored. Circuit means are provided to validate the received doppler signal, allowing their continual processing only after a preselected number of valid comparisons are made.

Abstract: A plague board comprises a solid polyurethane core enclosed by a high grade wood which forms all exterior surfaces thereof. A wooden frame is secured between the peripheries of a pair of spaced panels formed of flat sheets of veneer. The polyurethane core fills the interior of the frame between the veneer panels and is firmly bonded to the wooden frame and veneer. A method disclosed for constructing the plaque board and other like articles comprises inserting a measured amount of liquid polyurethane foam in the interior space between the attached frame and panels and pressing the opposite veneer panels inwardly as the polyurethane expands outwardly to solidify and become bonded to the frame and panels.
