  • Patent number: 4295697
    Abstract: An electrial power distribution block is secured to the lower portion of the metal frame of each space-dividing panel. The distribution blocks in an assembly of panels are electrically connected together. Wherever access to electical power on either side of a panel is desired, a slide-in duplex receptacle is mounted on the distribution block on that side. The receptacles interlock with the blocks to provide built-in stress relief, without separate mechanical fasteners, against forces generated by plugging into or removing a plug from the receptacle. The terminals of the blocks are recessed and the receptacle terminals which connect with the block terminals are shielded in plastic sleeve portions of the receptacles. The conductors of both the blocks and the receptacles are molded in place.

  • Patent number: 4273400
    Abstract: The invention provides a one-piece protective cap, discretely formed of semi-rigid material, which encloses the major area of a CRT base. The cap, which maintains alignment of the connector pins of the tube, completely shields the vulnerable areas of the base from possible contamination, and thereby prevents the possible development of resultant leakage and arcing thereacross. The cap is retained on the base by the utilization of a plurality of spatially-related nubbins in the cap interacting with the sidewall of the base to provide a plurality of pressured retention areas.

  • Patent number: 4167126
    Abstract: A control system for use in controlling the operation of an overdrive transmission of a vehicle. The system includes a circuit containing a relay coil and a limit switch in series relationship with the governor switch of the transmission. The relay has two sets of double acting contacts, one set being provided to control current flow to the coil of a solenoid used to actuate the overdrive and the other set providing a grounding effect for the distributor side of the ignition coil of the vehicle. The limit switch is mounted so that it is actuated and deactuated by merely moving the gear shift lever of the vehicle. To this end, the gear shift lever has a bracket which engages a switch arm of the limit switch to move the switch arm as a function of the movement of the gear shift lever.
