Abstract: An integrated insulator having a body adapted for placement in proximity to a module connector, and at least one fin extending from the body so as to extend through a connector slot on the module connector and reside in a gap between a pair of contacts when the integrated insulator is engaged with the module connector.

Abstract: A portable computer includes a processor, processor associated memory and control circuitry, and a memory disk drive assembly for storing software programs to form an integral computer unit. The integral computer unit has a CPU module, a display module, a user control module with a user control interface, module connectors, environmental protective barriers for blocking entry of EMI and moisture into the computer unit and a vibration isolator for energy absorbingly mounting the unit to the drive assembly. The display module includes a display device that is separately housed and removably interconnected with the CPU module. The modules are connected by hinges along at least one interconnecting edge of each module. The module connectors are disposed along at least one interconnecting edge of each of the modules to permit separation of the modules at non-hinged edges and pivotal movement about the hinged edges for improved accessibility.

Abstract: The present invention relates to front panel display construction for computers. The front panel includes a panel assembly secured to the computer having an opening formed therein so as to provide access to internal components of the computer. In addition, the front panel has a display member pivotably secured to the panel assembly which pivots between an open position and a closed position. In the open position the internal components of the computer are accessible to a user or operator and in the closed position, access to the internal components is inhibited.

Abstract: A movable support for indexing a recording head across the face of a recording tape in a deck in precision steps free of backlash and angular movement out of the normal plane of the tape and in which a pair of parallel, matched leaf springs carrying the recording head by their outer ends are anchored at their inner ends to a block adjustably secured to the frame of the tape deck such that the effective length of at least one of the leaf springs can be changed.

Abstract: Magnetically actuated impact equipment useful for high speed printers, punches or the like, is disclosed. Actuating magnets formed of materials characterized by wide hysteresis loops such as samarium-cobalt and mischmetal cobalt are disclosed. As disclosed, these magnets are oriented with like poles facing one another along opposite sides of gaps which run lengthwise of a print line. Magnetically actuated devices are shown with coils extending into the gaps with the plane of each coil being parallel to the print line. In one embodiment of the invention the magnets are arranged in upper and lower banks with coils on different movable devices extending upwardly and downwardly into gaps between the magnets in each bank. Another embodiment discloses coil-carrying devices which are mounted so as to be stepped along the gaps to various printing positions.

Abstract: There is disclosed a tape deck for receiving standardized tape cartridges for data interchange in which the cartridge is accurately positioned by the combination of the forward thrust of a pair of resiliently biased pivot plates working in the notches of the cartridges and the resilient upward thrust of a leaf spring, with the cartridge near the plane of the interface of the recording head with the tape, having precision reference bearing points engaging complementary positioning pins anchored in the deck. The pair of pivot plates are restrained to remain in phase by means of a cross-coupling linkage and means are provided for the automatic ejection of the cartridges.

Abstract: A harmonic insensitive phase sensitive demodulator which converts complex AC waveforms to a DC voltage proportional to the fundamental component at an arbitrary phase with respect to a reference voltage and eliminates, to any desired degree, the effects of harmonics of the reference frequency present in the complex AC waveforms.

Abstract: A tape deck for cartridge-encased record tapes in which the cartridge is precisely secured in a predetermined position in the tape deck in relation to its transducer and to the tape drive. The tape drive is interposed in the path of insertion of the cartridge to engage the tape-actuating mechanism in the cartridge when the cartridge is positioned in the deck. A drive motor is remotely disposed with respect to the cartridge and is coupled to the cartridge drive through a belt mechanism which allows displacement of the drive wheel through the agency of a flexural hinge support.
