Abstract: A detector of ferromagnetic materials having a permanent magnet floating in a contaier and restrained under the influence of a soft ferrite mass spaced below it to rotatable movement about a vertical axis centrally of the container. The magnet has a normal at rest position from which it is rotatable when a ferromagnetic material moves through its magnetic field. The magnet carries a curved mirror onto the concaved face of which a light beam is focused, and which beam in an at rest normal position of the magnet is reflected by the mirror onto a zero point of an observer's readout scale. When the magnet is caused to rotate from its at rest position by a ferromagnetic material moving through its magnetic field, the light beam is caused to move away from the zero point; and when the ferromagnetic material has moved out of the magnetic field, the magnet and light beam return to their normal positions but with some oscillation before doing so.
Abstract: A rotary file unit provided with radially extending shelves and compartments for the storage of files, which unit may be used standing alone or housed within a cabinet having opposed access openings. A door unit is rotatable within the cabinet relative to the file unit to effect simultaneous opening or closing of both access openings. Divider elements are provided for dividing the spaces above the shelves into compartments of various widths; and backwall members are provided for varying the depths of the compartments.
Abstract: A unit comprising a base on which is mounted an atlas of maps each with an arrow thereon indicating the relation of the map area to north, and on which base is also mounted a compass having in a container a liquid on which floats a magnet bearing disk on the surface of which disk is a visible pointer pointing in the direction of the magnet's north pole and the earth's magnetic pole. A ball of non-permanent magnetic material centered on a cover of the container cooperates with the magnet in maintaining the floating disk centered in the container and spaced below the ball. In use, the unit is turnable by the traveler until the arrow on the map points in the same direction as the pointer on the disk, thereby apprising the traveler as to his position relative to his surroundings.
Abstract: A magnetic compass having a magnet bearing float in a liquid and which float is self-centering and rotatable relative to an element of soft magnetic material spaced below it so as to align a pointer on the float with the earth's north magnetic pole and with the north point of a compass readout dial.

Abstract: A rear gun sight unit including a head having a U-slot across which extends a screw provided with a notch for sighting a target, the screw being adjustable to carry the notch to the right or left of normal center for sighting under adverse wind conditions, the head being vertically adjustable relative to a supporting base to elevate the notch for sighting a distant target, and the slot having sidewalls and shoulders to the right and left of center adapted for quick sighting of the gun under various conditions of wind and distance at a momentarily movable target.
Abstract: Apparatus for applying a label to the back of each of a number of computer cartridges seated in a container, including a slotted label stripping plate hinged to the container pivotable to position a separate slot over each cartridge, a sheet of labels to be seated on the stripping plate with a separate label over each slot, a manipulative plate for pressing the seated cartridges against loose movement, and a pressure mask plate hinged to the container adapted to be pivoted to press the labels through the slots onto the backs of the cartridges.
Abstract: A carriage comprises a base mounted on rollers for movement of the carriage under manual guidance over a work surface, a platform supported above the base on coil springs held in place by bolts fixed to the base and extending up through the springs and the platform, a tool mount slidable along the platform parallel to an edge of the platform and adapted to have seated therein an electric polishing tool with its polishing wheel overhanging the edge of the platform above the work surface, and nuts selectively threadable on the bolts against the platform to compress or relax the springs so as to lower or raise the platform and the tool relative to the base and the work surface.
Abstract: The invention provides a doll the arms of which are movable caressingly over the body of a child when the doll is held to the chest of the child with its arms about the sides of the child and when manual pressure is applied over the back of the doll. A compressible resilient sealed air filled container is disposed in the doll's body and has resilient flexible tubes sealed at their free ends and extending into the doll's arms. Upon the container being compressed under manual pressure applied over the back of the doll, air is pressured into the tubes causing the arms to caressingly move over the sides of the child. The arms and container relax upon release of the pressure.
Abstract: Apparatus for filtering impurities from the air of a room and recirculating its including a cabinet in which a motorized blower unit functions to intake room air and blow its through a filter unit into an upper compartment or the cabinet from where it escapes through multiple vents in the cabinet to recirculate in the ambient atmosphere of the room.
Abstract: The armature of an automotive starter motor has a protective collar for its commutator. The collar has an annular disc body that is bonded to the rear wall of the commutator, and it has a projecting rim which overlays the marginal free ends of the bars of the commutator so as to restrain them from a tendency to peel or lift away under the strong forces developed as the armature is rotated in cranking a motor vehicle engine. The body of the collar also has a rearwardly extending hub provided with grease-filled cavities, whereby the hub serves as a lubricated thrust washer and spacer for the armature relative to the end frame of the starter's housing, as the armature rotates.
Abstract: An instrument for making a visual examination of a blood culture bottle for the presence of microorganisms, the instrument having an elongated base on which is mounted a platform defining a seat for the bottle to be examined, a light source rearwardly of the platform for illuminating the bottle, a combined viewing and magnifying lens forwardly of the platform for magnifying the bottle to a viewer, and a manipulative control knob drivingly connected with the platform for rotating the latter while the bottle thereon is being viewed, both the light source and lens being arranged for focusing downward upon the bottle and platform.
Abstract: A bottle cap is disclosed for use as a closure and as means for pressurizing a previously opened bottle containing a carbonated beverage. It has a body adapted to close over the mouth of the bottle; and has a resilient manually compressible and relaxable bulb mounted to the body. The bulb functions as a pump in conjunction with inlet and discharge valves in the body to pressurize the interior of the bottle and its contents with air. A pressure release valve in the body responds to development of a pressurized condition in the bottle above a predetermined value to release the excess pressure to atmosphere.
Abstract: A vented heading for the outer frame of an airtight double-hung sash window unit adapted to be seated in an opening of an exterior wall of an apartment. Vent holes in a head panel allow fresh air flow into the heading; and a baffle member at the back of the heading serves to direct the airflow downwardly at the rear of the unit into the apartment. Stale air from the apartment is enabled to move past the baffle member and escape through the heading and vent holes to the outside.
Abstract: A draftsman's stippling device, small enough to be manually held during use, includes a vibratable cantelever bar supported in a small housing and having a free end projecting to the outside on which end a stippling pen is mounted. A cam disk having lobes about its periphery is adapted to be rotated by means of a battery powered mini-motor and reduction gearing at high speed against the upper surface of the bar. The lobes on the spinning cam disk successively depress the bar against the opposing tension of a return spring, whereby the bar and pen rapidly vibrate as a unit to enable stippling of a drawing surface disposed below the pen.
