Abstract: A rocker-type electrical switch of the kind known as a "quiet switch" includes a manually depressible rocker having two opposed contact surfaces at a small angle to each other from which rocker depends a rocker arm terminating in a rocker cam. A slider positioned intermediately of the rocker and the rocker cam is moved back and forth by side-to-side movements of the rocker arm and opens and closes one or more pairs of contacts. Rocker movement is controlled by a rocker cam leaf spring engaging the rocker cam which spring has a cammed profile traversed by the rocker cam to slow the switch, lock the rocker and provide other desirable effects. The rocker cam spring is housed in a spring chamber longer than itself, allowing the rocker cam spring to float.

Abstract: A display strap in the form of a flat belt of flexible material into which a number of tongues are cut each individually deflectable out of the plane of the strap about an unsevered end used as a hinge. The tongue has a cross-member at its free end and a portion of reduced width adjacent the cross-member. Two part slots are provided adjacent the hinge to receive the cross-member and then permit the tongue to be displaced into locking engagement between the cross-member and the rear surface of the strap. The looped tongue is employed to support elongate articles formed into multi-turn hanks.An alternative locking slot arrangement employs a tapered width locking slot which requires the tongue to be rotated to enter the locking slot making accidental opening of the loop very difficult.

Abstract: A lighting fixture composed of a lampholder which can receive an electrical lamp and supply to it AC power and a body member into which the lampholder can be placed for support and protection. A locking member in the form of a flat, resilient metallic band with end portions bent at an acute angle provides a one-way clutch which permits the lampholder to be placed into the body member but prevents its withdrawal. Channels in the interior wall of the body receive the band ends to prevent rotation of the lampholder. The channels are employed in pairs and a single pair or two pairs at right angles to each other are employed.

Abstract: A solid state motor speed control is described that is capable of controlling a motor so that it operates quietly, eliminating annoying buzzing noises that would otherwise be generated by the motor's windings. The invention provides for motor speed control with infinitely variable speed control settings. Rather than use triacs that generate RFI noise and cause motor windings to buzz due to their inherent avalanche switching, the invention utilizes power FETs or IGBTs to provide the switching function to control power delivery to the motor load . The power switches are controlled by an oscillator that generates a pulse train with a duty cycle controllable by the user. A filter shapes this signal into a trapezoidal control signal that drives the gate input of the power FET or IGBT switch. A kick start circuit turns the motor on initially for two to three seconds to overcome the inertia of the motor and its load.

Abstract: An adapter for lamps and other electrical devices to be installed in standard lampsockets which prevents unauthorized removal of such lamps or other electrical devices. A screwshell means is placed upon a body member such that relative rotation between them is possible. A tool or key placed in aligned slots or keyways prevents relative rotation so that the adapter can be installed or removed from a lampsocket. The tool or key is then removed permitting relative rotation again, whereby the lamp or other electrical device cannot be removed from the lampsocket. Use of the tool or key fixes the two components with respect to one another and the adapter can be removed.

Abstract: A ground fault protection circuit for plural loads connected across a power source with plural branches which can be used where the loads are unbalanced. Each branch includes a ground fault circuit interrupter device that has a common line for the electronics of the GFCI separate from the neutral line from the power source to the load where the common lines for the electronics for the ground circuit interrupter devices in each branch are connected to a common point. The ground fault protection circuit employs plural ground fault circuit interrupter devices and eliminates nuisance tripping. The common line for the electronics for a GFCI is routed through the core of the current sensing transformer of the GFCI. The separate neutral line for the electronics, connecting the common lines for the electronics for plural GFCI devices and routing the common lines for the GFCI electronics through the core of the transformer of each GFCI, eliminate improper GFCI operation due to unbalanced loading.

Abstract: To prevent the contacts of an electrical switch bouncing when the switch is operated, with the attendant arcing and contact erosion, spring mass mechanisms are added adjacent the spring arms and contacts to engage such spring arms and contacts and transfer the vibrational energy to such spring mass mechanisms and permit the spring arms and contacts to operate without any contact bounce. An energy absorber can be used alternatively to absorb the vibrational energy. A combination of spring mass mechanism for one spring arm/contact assembly and an absorber for the second spring arm/contact assembly can be employed.

Abstract: A lamp housing to support and power a compact dual or quad-tube fluorescent lamp. A body portion with a central cavity receives the lamp base and selectively retains same using a trapped metal clip; contacts mounted in separated cavities receive the lamp leads at a first end and at the second end the bared end of an electrical conductor inserted into a one way type clutch contact lever to apply AC power to the lampleads. The contact lever can be bifurcated to independently engage more than a single conductor. The lamphousing can be mounted to a panel using fasteners extending through apertures in mounting pads of the base, or by using flexible mounting tabs to grip the underside of a mounting panel or a combination of the flexible mounting tabs and flexible arms to permit the lampholder to be mounted on panels of different thicknesses.

Abstract: A cable bundling strap anchor made by forming a number of tongues along an elongate band or bracket of flat, resilient metal or plastic by removing material in a form of a cutout such that the sides and one end of the cutout form a tongue attaching member. An open bundling strap is placed around the tongue from the tongue free end. Thereafter, a cable bundle is placed over the anchor and the strap is closed about the bundle. The stiffness of the cable bundle and the inability to move the bundle away from the plane of the band prevents removal of the strap from the anchor.

Abstract: An electrical rocker type wall switch capable of single, duplex and triplex configurations incorporates one or more slightly concave manually depressible rockers. These rockers have a relatively short range of motion from their respective on to off positions. The edges of the rocker lie substantially flush with the switch cover when in either of their on or off positions. Switching is actuated by an actuating arm attached to the rocker moving a contact on the end of a movable brush arm in and out of electrical contact with a fixed contact on the end of a contact arm attached to a fixed terminal. One or more brush arms extend from a fixed brush backplate and are formed so as to be resilient.

Abstract: A differential transformer includes a magnetic core within which difference signal detection inaccuracies resulting from non-homogeneity within the core are corrected by compensation. A phase wire extends proximate the magnetic core for transporting a first current in a first direction. A neutral wire extends proximate the magnetic core center for transporting a second current in a second direction which is substantially opposite the first direction. A shunt wire is electrically connected to one of: the phase wire and the neutral wire depending on whether the transformer is undersensitive or oversensitive. The shunt wire shunts a portion of the current flowing in one of the phase and neutral wires such that first and second signals are generated in the transformer as a result of said first and second currents that are substantially equal.
