Abstract: An apparatus for feeding flat, rigid material through a cutter comprising a continuous drive conveyor belt with a non-skid face, having one or more Guide ‘V’ belts bonded to its reverse side parallel to the direction of movement, which ‘V’ belts communicate with corresponding ‘V’ grooves in the power rollers and the rollers of the feed bed, another continuous drive conveyor belt on the out-put side of the cutter, the movement of both conveyors being synchronized by a timing/drive belt which transfers the motor drive to the inside rollers of the out-put and the input sides, and having from above regularly spaced hold-down rollers along the span of both conveyors to keep the rate of movement of the flat material through the cutter consistent. This apparatus has its preferred application in the lumber industry for trimming defects and/or wanes from wood boards, so that the boards maintain consistent position in the horizontal plane while traveling through the cutters.

Abstract: An improved apparatus for feeding flat, rigid material through a cutter comprising a continuous drive conveyor belt with a non-skid face, having one or more Guide ‘V’ belts bonded to its reverse side parallel to the direction of movement, which ‘V’ belts communicate with corresponding ‘V’ grooves in the power rollers and the rollers of the feed bed, another continuous drive conveyor belt on the out-put side of the cutter, the movement of both conveyors being synchronized by a timing/drive belt which transfers the motor drive to the inside rollers of the out-put and the in-put sides, and having from above regularly spaced hold-down rollers along the span of both conveyors to keep the rate of movement of the flat material through the cutter consistent.

Abstract: A production line for manufacturing wooden I-beams wherein a pair of grooved flanges are conveyed along opposite left and right sides of a train of web members and converged so that the web longitudinal edges are inserted into the flange grooves is disclosed. The flanges are moved along left and right hand chutes of the assembly machine with plural vertical flange drive rolls engaging the wider flange faces for improved traction. These flange drive rolls and the chutes are mounted to the machine base with a lateral adjustment mechanism permitting center justified adjusting movement relative to the machine center line. The lateral adjustment mechanism utilizes a series of lead screws each formed with left and right handed threaded portions engageable with a threaded nut attached to each chute. A pair of web bottom rails are vertically adjustable in elevation with plural vertical column screws connected between the machine base and the support rails.

Abstract: In a production line for manufacturing wooden I-beams in a chords and webs assembly machine, a vacuum belt conveyor system is provided to sequentially feed bottom web members from beneath a web stack into a web run-up and drive system associated with the machine. The vacuum belt conveyor system features a vacuum supply box mounted between the web support rails through a series of vertical screw adjustment assemblies permitting adjustment of the inclination of the conveyor belt relative to the head drive pulley. A system of vacuum supply holes in the top plate of the vacuum box is utilized to apply a greater amount of vacuum to the leading end of the webs than the trailing end to minimize belt wear.

Abstract: A corrosion resistant electromagnetic interference shielding material for electronic enclosures is provided. The corrosion resistant composite material comprises a metallized, highly conductive porous polymeric material, laminated between two layers of corrosion resistant composite materials, incorporating ground lugs. The highly conductive material intercepts an electromagnetic interference signal and grounds the signal through the ground lugs provided in the outer composite shell. This invention is particularly useful where a lightweight, corrosion resistant electronic enclosure is required.

Abstract: The weight of a start cartridge in a cruise missile (10) of the type having a booster rocket (60) for initiating flight and a thrust producing gas turbine (12) for sustaining flight may be eliminated by placing the gas outlet (62) for the rocket engine (60) in ducting (64, 82) downstream of the gas turbine engine exhaust (20) so that operation of the rocket (60) to initiate flight of the missile (10), through eduction, draws sufficient air through the engine (12) to accelerate the same to starting speed.

Abstract: A patch electrode for use with defibrillators is provided. The patch electrode comprises a soft, flexible patch of polymeric material and bonded to it, a smaller patch of polymeric material that has been metal-plated. A lead wire is attached to the patch by a polymeric boot. A defibrillator system is also provided wherein two electrodes and lead wires are attached to a generator typically used for cardioventing and defibrillization. The invention is particularly useful for cardiac muscle stimulation but can also be used for muscle stimulation.

Abstract: An improved package for needled sutures comprising a plastic pack for one or more PTFE (optionally silk, cotton or other) sutures sealed within protective plastic envelopes wherein the suture is arranged within molded compartments of the pack, spaced apart by thin plastic spacers where multiple sutures are housed, and the needles firmly held across a U-shaped slot at the top of the holder by tabs or in curved slots so as to be easily accessible from either side of the pack when the protective envelopes are opened.

Abstract: An improved package for needled sutures comprising a 3-panel folded paper folder for PTFE (and optionally silk, cotton, and other) sutures wherein the suture is arranged in a sinusoidal configuration within the folder and the needle(s) held firmly in place across a U-shaped slot at the top of the folder which allows ready access from either side of the folder when the protective envelopes are opened.

Abstract: A device or mechanism which converts rotary motion into linear motion. The mechanism is well adapted for converting rotary movement of a pulley which is driven by a stepper motor responsive to signals from a computer into linear motion of a magnetic head. The magnetic head is mounted on guides for linear movement with respect to a record. A flexible metal band is wrapped around and attached to the driven pulley, the ends of the band extending tangent to the pulley and parallel to each other, the ends being secured to the block or carriage carrying the magnetic head. Angular movement of the pulley tends to unwrap one end portion of the band and to wrap the other portion thereby moving the block carrying the head linearly.

Abstract: A record drive and positioning assembly particularly adapted for disc records used for recording of digital information and for use in association with computers. The unit embodies a record driving spindle or hub and clutch. The record is insertable into the unit through a hinged door. Ejector mechanism is provided in association with a latch, the ejector being operative to eject the record unless it is inserted fully in a latching position. The mechanism provides for "feel" so that the operator will know when the record is fully inserted. During closing of the door, a pin will unlatch the ejector allowing the ejector to move the record sufficiently to cause it to accurately register with the driving hub and clutch. When the door is opened by being lifted, the ejector will eject the record from the unit.
