Abstract: A fitting mounted on the bottom of a cell in a cellular raceway. A hollow cylindrical member engages and is secured to the bottom of the cell in alignment with a bore in the bottom. A junction box is mounted on the lower end of the cylindrical member and has an opening aligned with the member. Intumescent wafers are inside of the cylindrical member and are formed to permit passage of conductors. Discs restrain the intumescent wafers from expanding into the cell and junction box. Electrical conductors can extend from the junction box to the cell.

The other being a small, precise, screw-thread adjustment which may be made when the support is in any one of the large adjusted positions.

Abstract: For a preset having a cover and an annular ring supporting the cover, structure to releasably hold the cover in closed position and to move the cover with respect to the ring as between closed and open positions, the structure including a deforming surface on the ring; a deformable head on the cover to engage the surface, the engagement causing the deformable head to deform and generate friction forces sufficient to hold the same against said surface means for holding the cover in closed position but permitting the deformable head to slide relative to the surface means to provide for the cover to be moved out of or into the closed position; an elongated lifting tab on the cover; and the lifting tab being pivotally mounted for movement between an inactive condition and an active condition, in the latter condition part of the tab extending inwardly of the cover and part of the tab extending outwardly of the cover to be grasped by the fingers for moving the cover from closed to open position.

Abstract: The invention contemplates an improved air flow sensor including a proximity switch which has a metal disk mounted with respect to the sensing face to be movable by air flow in the action zone of the magnetic field as between a position adjacent the sensing face to a position away from the face or visa versa whereby the switch oscillator is off and on respectively at the two extremes to provide an indication of the condition. The air flow sensor is shown herein in apparatus to calculate breathing rate, in object detection apparatus, and in vacuum lift apparatus.

Abstract: Each component includes one or more sets of pin and/or socket contacts each set being mounted on a contact block. The contact block has shield means surrounding the contacts and around each shield means in an outer housing. The shields and housing electrically and mechanically isolate the contacts.

Abstract: Method contemplates: providing a set of collapsed multi-cell, crossed panel separator partitions arranged in upright position along a horizontal axis; applying vacuum grip to pull out the lead partition and move along the axis to a transfer station; relieving the pull-out vacuum grip and while supporting the partition in the upright position moving the same away from the transfer station along a second horizontal axis normal to the first axis to an opening station; applying vacuum grip to opposite sides of at least a single panel and rotating the panel to open the partition; and while the gripping force for opening is on the panel, moving the partition along a vertical axis down to an insert station and then removing the gripping force to thereby deposit the partition on the medium for which it is to serve its separating function.

Abstract: Equipment for aluminum siding applicators which has support and datum surfaces to receive, support, and align an aluminum trim strip to be punched with datum dimples and a spring biased punch which can be moved relative to the aluminum trim strip to any position where a dimple is to be made.

Abstract: A light director has an elongated, hollow, opaque open-ended shield. The shield slips over the glass housing of a light bulb. A pair of small apertures on the side of the shield receive portions of the glass housing in a sliding engagement which provide for the shield to be oriented in several angular positions. A plurality of flat, spaced apart slats extend across one open end and function to cause the light to exit in generally parallel beams.

Abstract: Device for preventing bed clothing from exerting pressure on the feet. The device has a base portion to fit between the mattress and the box spring, a connector portion that extends vertically, and a support portion that extends horizontally over the mattress. These portions are formed from rods and pivots rotatably mounting the rods. This stucture allows the device to be folded flat for storage and to be folded to the desired shape for use on a bed.

Abstract: The unit has a flat base to be postioned over the cellular raceways with appropriate openings to the communication raceways (telephone/data) and to the power raceways together with a housing on the base having a central or main section (accessible from the floor for wiring), a pair of power sections respectively disposed on opposite sides of and open to the main section and open to the power raceway and providing passageways for conductors between the main section and power raceway together with a pair of communication sections open to the communication raceways and respectively disposed in the other opposite sides of and open to the main section and providing passageways for conductors between the main section and the communication raceways. In a modified version, the power sections are eliminated and the receptacles are mounted on a support inside the main section.

Abstract: A water saver unit to be immersed in an filled with the water of a water-flush toilet system, the unit comprising a hollow body having a pair of clearance holes disposed diametrically opposite one another; a slot formed in the body and connected to and extending between said clearance holes, the slot and clearance holes providing communication between the outside and inside of the body to permit the body to be filled with water. The body being formed of flexible material so that pressure applied adjacent each said clearance hole and respectively directed toward the center of the body caused the body to distort, which distortion cause the slot to increase in width and so that when said pressure is relieved, the body will return to the non-distorted condition wherein the width of the slot is the same as before said distortion; and a weight inside of said body and being in the form of an annular member, having a central clearance aperture and a slot extending from the aperture to the periphery of the member.

Abstract: In an integrated container packing system where a mass of randomly oriented containers enter the system and are manipulated so that a partition can be inserted between groups of containers and then each group with the partition are placed in a shipping medium ready to be sent to inventory, the method of inserting the partition by relatively moving the containers and the partition in a forward direction, controlling the relative motion so that in alternately occurring periods of time, the velocity of the relative motion during one period of time is zero and during the next period of time the velocity of the relative motion gradually increases from zero to a maximum and then gradually back to zero and during each time the relative motion velocity is at zero, inserting the partition between a group of containers.

Abstract: A trench duct power compartment for use over a cellular raceway is fabricated by forming a rectangular-shaped blank and then stamping out a center section to leave portions which are contoured to the shape of the crests of the cellular raceway and thereafter bending the cut-out blank to simultaneously form upright side walls, downwardly extending concrete blockers together with connecting bottom end sections while leaving the bottom midsection open. The contoured portions of the concrete blockers having the same profile as the crests of the cellular raceway and snugly engage therewith.
