Abstract: A "green" sheet manufacturing method and apparatus contemplates perforating the "green" sheet with through-holes as it is calendared, rolled or extruded by rollers. To this end, the rollers are each machined with punches of a length one-half the thickness of the "green" sheet and that mate with punches on the other. Any flash or diaphragm obtaining in the through-holes are removed by subsequently exposing the "green" sheet to new mechanisms providing fluid pressure or vibration, or spiking. The bosses or punches may be supplemented with enlargements and other bosses providing for pads and counterholes and grooves in the "green" sheet. The through-holes may be shaped to have a smaller diameter interiorly than at the outer edges to lock in place solder or other conductive media squeegeed into them. The locking action may be enhanced by slightly off-setting bosses or mating punches to produce through-holes whose top and bottom halves are slightly off-set.

Abstract: Stiff ink in a ink fountain of a high-speed printing press or the like is maintained at the viscosity necessary to wet a printing roller by vibrating a rod placed in the ink in the fountain. The rod is mounted on arms pinned to trunnions, one of which trunnions is fixed to an air turbine oscillator. The oscillator when activated, transmits vibrations to a trunnion to which it is fixed. The vibrations pass on to the associated arm and on to the rod to agitate the ink. The trunnions are mounted on vibration isolators on the cheeks of the ink fountain. The rod being mounted via the arms on the trunnions, is swingable in and out of the fountain for cleaning purposes as on ink changes.

Abstract: A rectangular vehicle license plate frame includes side columns which mount printed circuit boards internally. The printed circuit boards mount yellow dot transformers and an integrated chip and light a number of light emitting diodes mounted on the external surface of the columns proportionate to the strength of the signals received. The strength of the signals received is dependent on the output of the respective channels of the vehicle's stereo system to which the printed circuit boards are connected by appropriate wires. Connections to the vehicle's battery provide power for energizing the respective diodes. Thus the license plate frame displays an unlimited variation of patterns in which various numbers of LEDs are illuminated in accordance with the strength of the outputs of the stereo system in rhythmic-like fashion.

Abstract: A microwave oven moisture analyzer is provided with an analysis chamber using a V-shaped structure wherein the wings extend from a vertical back wall forwardly and outwardly to the side walls of the oven. The upper edges of the wings also rise as the wings extend, to where at their ends they engage the ceiling of the oven. A roof rests on the wings and slopes downwardly rearwardly. The back wall is shorter than the adjacent wing portions and hence an opening exists from the analysis chamber into the rest of the oven. Air flowing down over the roof creates a venturi effect at the opening to remove air from the analysis chamber. A four point arrangement supports a fiber-glass pad bearing a sample in spaced relation to the floor and the sides of the chamber and below the opening so that moisture evaporated does not have a place to condense before it is removed from the chamber.

Abstract: The lower portion of the outdrive of a stern drive motor or of an outboard motor for boats, is further protected from damage on striking submerged objects. Protection at low speed is gained by providing sharp or knife-like edge formed of rubber on the leading of the lower portion to gain the resiliency to cushion from damage at low speeds. Lower portions are typically pivotally mounted with respect to the rest of the motor to enable trim adjustment by a cylinder and piston arrangement. The cylinder and piston arrangement provides some cushion enabling damage-reducing backwards and upwards limited rocking on impact at low moderate speeds. Impact sensing mechanisms conventionally also release the pressure in the cylinder and piston arrangement at low and low-moderate speeds but are generally ineffective at moderate and high speeds to limit damage.

Abstract: A portable, compact, light weight, machine for gluing a flexible veneer strip in a groove of a work piece. The gluing machine includes an aluminum housing having a chamber in which an electrical heating tape obtains. The housing is mounted on a base of wood though separated therefrom by a commercially-available BACALITE heat insulating strip. The user is protected from the heated housing by side strips of BACALITE. A slot in the bottom of the housing mounts a readily interchangeable, high-heat transfer bar whose free edge has a surface complementary to that of the groove in which a veeneer is to be fixed. Special side bars are employed for grooves have greater internal dimensions than their openings. A controller also mounted on the base may be utilized to regulate the heating tape.

Abstract: A high speed microwave high temperature oven system mounts an enclosed furnace in its cavity and extends a temperature probe therein. A controller regulates the furnace temperature by periodically interrupting over a range, the operation of the magnetron as the furnace or actual temperature approaches the setpoint. It interrupts the operation of the magnetron for longer periods of time as the actual temperature nears the setpoint. If the actual temperature exceeds the setpoint, the operation of the magnetron is interrupted for even longer periods of time. The controller at a selected furnace temperature also activates an exhaust function to remove hot air, smoke and fumes from and draw clean air into the furnace. As the actual temperature lowers towards the setpoint, the controller shortens the period of magnetron operation interruption. When the furnace temperature cools to a safe temperature, the controller shuts off the exhaust function.

Abstract: A golf putter is formed with a hollow box open towards its striking face which is tautly covered with a layer or two of leather. The cavity in the box behind the leather is filled with a displaceable material such as sand or liquid. The leather indents on striking a golf ball to provide more "feel" and accuracy.

Abstract: A bird-feeder, which precludes gray squirrel access to seeds therein, mounts on a rectangular platform gnaw-resistant, hollow, 3/8" aluminum bars across the front and partially back along the sides and whose surfaces are spaced from adjacent bars 11/4". The upper ends of the bars are received in an open frame closed off by a plexiglass roof. A generally interior hopper extends across the back of the feeder to constitute its rear wall and to gravity feed seed onto the platform surface constituting the floor of the feeder. The hopper is pivoted to the platform for swinging movement outward to a loading position. Solid panels on the rear portions of the two sides present resistance also to wind action and seed scattering.

Abstract: A power-driven voicing tool simultaneously inserts into and withdraws from the felt of a piano hammer, needles to raise a nap thereon. A row of four needles is driven by two circularly moved cam surfaces on the ends of an assembly rotatable by a variable speed electric motor through a flexible drive cable. One cam surface lies outside the other and drives the external needles of the row of needles; the other drives the internal needles. The slopes of the two cam surfaces are different and one-hundred-and eighty degrees out-of-phase with each other and effect different movements in adjacent needles, one needle moving outward while the other moves inward. A process of inserting a needle while withdrawing an adjacent needle in the felt of the piano hammer, is practiced.

Abstract: Complex edges of workpieces are veneered by stretching a thin flexible veneer strip over the edges and moving the workpiece edge against a yieldably mounted heated bar having a complementary surface to seat the strip and bond it the workpiece edge. The yieldably mounted bar moves in a second direction as it is moved by the workpiece to fully seat the veneer strip before the adhesive previously applied to the edge is heat-set by the bar.

Abstract: A portable outdoor grill includes a round, smooth stake having a T-shaped upper end to facilitate insertion and removal from the ground. An E-shaped double-hook having at each end a hook making contact with the post at two separated points, mounts on its external side a sleeve that slidably receives a horizontal arm. One end of the arm is for mounting a cooking utensil over a source of heat, and the other end mounts a wooden handle. The cooking utensil may be a wire basket having a wire lid allowing cooking of the other side of the food on rotation of the basket; two lid levers embracing the arm preclude opening of the lid on rotation of the basket. The basket may be replaced a Y-shaped bar whose branches have arcuate shapes providing three-point support for a range of differently sized cookware.

Abstract: A sandwich panel has a core formed of a plastic sheet having columns of equally spaced points displaced from one side, and other columns of similarly spaced points displaced from the other side, the columns on the two sides being interleaved and the points in adjacent columns on the same side being staggered, with the points in the other-side columns being disposed in rows with the oncoming one side column. The displaced points on a side form somehat cone-like structures which intersect the cone-like structures formed by displaced points on the other side to form structures constituting tetrahedrons and octahedrons when assembled and cemented between the layers of a panel. An apparatus and method for forming the core from a heated plastic sheet, involve passing the sheet between two rollers having projections which displace the points to each side. Another apparatus and method involve forming core shapes over stationary projections. Complex and compound structures may be created.

Abstract: A standard attachment temporarily converts a drywall screw gun into a drywall router-bit cutter. Adapters unique to particular brands of screw guns may be employed to allow the standard attachment to be mounted on guns of the different brands. The attachment effects a twenty-times speed-up of the screw gun screwdriver RPMs to achieve required router-bit RPMs, while depressing a special function of the screw gun. Snap rings and snug slidable fittings are utilized to effect quick attachment/detachment. A belt clip on the attachment facilitates maintaining the attachment readily accessible. In an alternate attachment form, an external portion of the housing is substituted to allow the attachment to be mounted on guns of different brands. Different types of the attachment forms allow mounting on guns which may or may not have their depth control mechanism adjustable sleeves readily removed.

Abstract: Conventional golf tees and markers are modified to provide golf club face and club face groove cleaners. The heads of tees and markers are formed square rather than round to provide straight edges for scraping the faces of dirtied golf clubs and with the edges intersecting to form sharp corners for insertion in club face grooves to facilitate eviction of the dirt therein. The stems of tees may be made of wood and the heads thereof of a molded material to provide superior cleaning capability.

Abstract: A rail finder for railroad bridges is compactly and uniquely designed to minimize false signals and decrease replacement and maintenance costs. A weighted lever mounted on switch-box rotatable shaft that is perpendicularly disposed with respect to the rail, has an offset portion directly engageable by a horizontal plate mounted on the inner surface of a rail on a bridge. The plate holds the lever in a horizontal position in the down position of the bride. When the bridge raises, the weighted lever follows the plate and rotates the switch box shaft to where cams move switchable elements from a set of contacts. The contacts of the set are in circuit with green lights permitting train passage when the cams are out of contact with the switchable elements. The compact arrangements allow a pair of rail finders to be mounted side-by-side within the gauge and thus out of the path of loose or low third-rail shoes of electrically-powered trains.

Abstract: Apparatus for discharging sheets having skins on them and different patterns, characteristics, and properties. One or more rollers, belts, plates, or combinations thereof, having cavities and projections of desired patterns formed on their surfaces, pass through low pressure liquefied extrudable materials to be bathed thereby and pass by another surface(s). Heating or cooling is applied as appropriate to the roller(s), plate(s), belt(s), to form a skin on the extrudate and/or set same. A distributed low pressure, mixed orientation, low gas, liquefied extrudable material is generated using a vented barrel assembly and manifold mechanism. By using a dynamic moving die surface, bathed in a low pressure material chamber, rather than extrudable material forced through a fixed die opening as is normally done in extrusion processes, a product with low stress and one that exhibits isotropic properties results.

Abstract: A very lightweight sandwich panel is constructed using as the core layer a very thin plastic sheet that has been preformed with projections having broad bonding areas on their free ends for chemically cementing to one outer layer of the panel and with areas between the projections for bonding to the other outer layer. The projections may be made of different cross-sectional shapes, heights, spacings, tilts, profiles, etc., to produce different characteristics in the panel. Differences may even be made in a given sheet to produce a panel having different characteristics in various portions, including shape and function. These characteristics can be predetermined, and the panels may therefore be computer designed. Special panel applications such as airplane wings and thermal boards are comtemplated.
