Abstract: A method of fabricating very fine metal screens for use in a transparent or translucent panel through which visible light is transmittable but which acts as a barrier against transmissions of pulsed electromagnetic radiation which may be harmful to humans or disruptive to electronic gear. The screens are fabricated by printing a pattern photographically upon a first surface of a metal foil covered on both sides by a positive, photo sensitive etchant mask and removing exposed areas of the mask with a developer. The masked foil is then chemically blanked by application of an etchant to the first side only of the foil. The specimen is rotated 90 degrees on a frequent basis to prevent selective etching, especially in areas adjacent the periphery of the screen.

Abstract: The invention relates to a magnetic tumbler lock comprising an inner cylinder adapted to turn in an external housing, said inner cylinder having a keyhole for receiving a key, locking means including at least one magnetic tumbler, which is adapted to rotate about a rotary axis extending substantially transversely of the longitudinal axis of the inner cylinder, and a key which is provided with a magnet for co-operating with the magnetic tumbler causing the magnetic tumbler to rotate into an unlocked position when the key is inserted into the lock.

Abstract: An apparatus is disclosed for a two-stage crushing of empty cans along their longitudinal axes to collapse them to minimum bulk. The apparatus has a stanchion fixed to a base and long and short lever arms pivotally mounted on the stanchion. A pivotal linkage interconnects the long lever arm with the short lever arm. First and second crush heads are pivotally mounted between the base and the long and short lever arms with a pantograph type linkage to control the attitude of the crush heads.In the first stage of crushing, the can is placed between the first of the crush heads and the base, and the long lever arm is moved toward the base to partially crush the can axially. In the second stage, the partially collapsed can is placed between the base and the second crush head. The long lever arm is moved toward the base thereby moving the short lever arm toward the base and the can is thereby completely axially crushed.

Abstract: A method of preparing the upper end of a concrete column containing elongated reinforcing elements for connection to a cast-in-place beam supported by the column. The method comprises the steps of determining the elevation at which the column is to engage the beam, severing the column a distance above said elevation, axially core drilling the column to said elevation, scoring the outside of the column at the elevation by use of an abrasive saw, crushing the shell of the column about the area previously core-drilled to fracture the concrete and free the elongated reinforcing elements, and finally bending the elongated reinforcing elements into a position in which they tie into the cast-in-place beam structure to be supported by the column.

Abstract: A tool stand comprising a series of end interfitting and fastening rectangular conduits. Each rectangular conduit has an axially disposed protruding block at one end thereof and an axially disposed recessed block at the opposite end thereto, the recessed block of one conduit being for engagement with the protruding block of a second conduit and with a threaded fastener being inserted in an axially disposed hole in the conduits to provide a fastening engagement of the conduits. Additional conduits are identically equipped for engagement in a sturdy conduit series.

Abstract: A core drill stand for orienting and holding a core drilling apparatus for sampling concrete pilings, comprising an elongated column having a support collar fixed at right angles to the elongated column for engagement with the top of a concrete piling, gripping standoffs between the column and piling, a tightening collar to tighten the apparatus to the piling and a movable carriage means supported by the column, the carriage means being adjustable to fit closely about the column and having a pinion drive means engaging a rack on the column for moving the carriage along the column. The carriage is adapted to receive a pneumatic drilling device, other tools or additional columns. Columns are equipped with interfitting end hardware so that a plurality of columns may be joined endwise.

Abstract: A vibratory ribbon speaker according to this invention as disclosed comprises a series of permanent magnets secured on opposite faces of a pair of soft iron bars mounted in edge-opposed, spaced-apart relation providing an air return flux path and a working air gap in which is suspended an elongated wavy or corrugated non-magnetic ribbon, several feet in length, flexibly and resiliently supported in said air gap at numerous spaced-apart stations along the ribbon length.

Abstract: A self-propelled hydraulic power supply vehicle and tool mounting platform having an hydraulic fluid reservoir integral with and forming the structural frame of the vehicle, hydraulically actuated driving and steering apparatus for moving the vehicle across a support surface while performing a cutting operation on the support surface, and castor wheels facilitating vehicle mobility which are rotated into operative position raising the vehicle so that the wheels normally supporting the vehicle are raised out of contact with the surface for mobility when the device is not cutting the support surface.

Abstract: A saucer shaped flying toy has imbedded therein a chirp producing whistle device which operates when the toy is thrown and spun in either direction. The whistle has a raised portion with an elongated sharp-edged opening. The raised portion extends into the airstream passing over the toy to provide turbulent air flow past the whistle opening.

Abstract: A one-piece gutter hanger bracket has a nail guide portion located in its mid-section. The nail guide positions the head of a nail angularly upward with respect to the main body of the hanger bracket so that the nail head is easily accessible to a driving tool. A nail driven through the nail guide provides additional support to the mid-section of the bracket.

Abstract: A method of bonding a cover glass to a semiconductor substrate having conductors thereon. The cover glass and the semiconductor substrate are placed in a relatively high voltage field and heated to induce ion drift in the glass and improved conductivity in the substrate. Additional localized heating softens the cover glass in the vicinity of the conductors permitting the cover glass to flow around the conductors and to be drawn into contact and bonded with the substrate.

Abstract: A composition and process for the removal of phenolic resin composites from aluminum and its alloys which results in a minimum of corrosion to said metals. The process uses a solvent solution of nitric acid, a hexavalent chromium and incidental water in the proportions of about 0.01-0.12 moles of hexavalent chromium and 1-1.7 moles of H.sub.2 O per mole HNO.sub.3.

Abstract: Protective paper adhesively bonded to stainless steel surfaces is removed by applying an aqueous solvent mixture containing a ketone or similar solvent, alcohol, toluene, and a wetting agent, all of which are maintained in a single phase. The relative composition of the solvent components is maintained on the area of solvent application by covering with a suitable airtight cover. The single-phase solvent mixture penetrates the paper and adhesive, and the vapor pressure of the solvent mixture causes the paper and adhesive to blister and loosen. The paper is peeled off after sufficient time elapses. Any remaining adhesive can be removed with a second solvent containing a ketone and toluene.

Abstract: An animal feeding system employs an openwork manger suspended in such manner as to cause a feeding animal to raise its head in grasping hay between opening of the manger and upon pulling tending to tear hay flakes and bunches apart. Means is provided to discourage animal penetration to beneath the manger thus precluding fouling of that area and possible animal bunching in restricted space.
