Abstract: A cubic magnetic core storage memory system which results in increased packing density of the core elements and more economical construction. Memory cores are bonded flat to carrier planes. The carrier planes are then stacked, forming a three dimensional array which is wired with X, Y and sense/inhibit lines. A parallel group (word) of binary digits is geometrically defined by a vertical line drawn through memory cores on the common intersection between an X and a Y coordinate wire on the successive carrier planes of the three dimensional array.

Abstract: A female guidance and polarizing means for either the male or female parts of a separable electrical connector which carry mating eletrical contacts. The polarizing and guide means is mounted in predetermined positions on either the male or female connector parts. The removable bushing has a portion which is keyed to the male polarizing pin to permit the connector parts to be mated only when the correct parts are presented to each other. The removable female polarizing guide bushing is made of resilient plastic material having a keyway, a flange, a polygonal body section, and a plurality of fingers with shoulders for engagement with the connector parts. The bushing is inserted into a bore in the connector body. The bore comprises a series of three axially aligned apertures. The fingers snap into one of these apertures and the bushing is thereby retained from moving longitudinally in one direction. The flange fits into an aperture which has a diameter greater than that of the flange.

Abstract: An improved energy saving control apparatus particularly designed for providing energy saving control of individual room heating and cooling units in direct response to the active occupancy status of the room. Switching means selectively interrupt energization of the load element of a room heating/cooling unit in response to an interrupt control signal. An electronic energy saving control circuit responds to changes in the ambient air room temperature and overrides the heating/cooling unit thermostat to selectively generate the interrupt control signal for maintaining the ambient air room temperature within a broad predetermined and pre-settable energy saving temperature range whenever the room is not actively occupied. Occupancy status detector means, including a uniquely detectable and detachable member typically carried by the room occupant and cooperative detector means within the room provides a real time indication of the active occupancy status of the room.

Abstract: An apparatus for connecting blade type male contacts to external circuitry. Tuning fork type female contacts are press fitted into a printed circuit board and an insulative housing is snapped over the top of the contacts. The structure of the insulative housing provides a closed entryway for blade type male contacts to protect the tuning fork contact ends from damage during connection.
