Abstract: Abstract of the Disclosure Control system including radio receiver circuit for power-driven operator for garage doors and like comprising an operator control circuit having a regulated DC voltage source operating as a power supply for an electronic flip-flop device responsive to successivley applied input signals to establish circuits of opposite direction through a reversible electric motor; i.e., one actuation causes the motor to run in one direction and the next actuation causes it to run the opposite direction.  The operator is subject to actuation by both a hard-wired push-button and a radio receiver which is responsive to signals from a remote transmitter.  The power receiver; however, the receiver is packaged separately from the operator and power supply and is readily disconnected for independent maintenance and repair.

Part of the member is a bobbin with a coil mounted on it situated around the space.  The space extends the entire length of the member which is open at both ends.  Fixed contacts extend into the protective space and a contact actuator is mounted in the space so as to extend along the bobbin while having a free end in proximity to the fixed contacts for cooperation therewith.          Terminals are connected to the coil, to the actuator and to the fixed contacts.  These terminals are embedded in and extending outwardly from the structural member on opposite sides thereof in the longitudinal plane.

A second skewer rod end nut opposite the first end nut is formed with a substantially smooth outer surface that is continuously inclined with respect to the axle.  This surface configuration prevents removal of the locked hub assembly by turning the second end nut with a pliers or other tool.  The lever arm lock also pre-vents the hub from being jarred loose on impact with curbs, rocks, etc.  The end nut assemblies have extensions which abut the frame thereby preventing loosening thereof for unauthorized removal.

Abstract: SELF-REGISTERING METHOD OF FABRICATING FIELD EFFECT TRANSISTORS     Abstract of the Disclosure A method of fabricating a field effect transistor (FET) wherein a self-registered or misregistration tolerant electrical connection is provided between the gate electrode and a metallic interconnection line.      The method involves a unique structure which includes a thick deposited oxide insulation layer and an etch stopping layer over doped silicon source and drain regions, over polysilicon gate electrode regions, and over field isolation regions.  The etch stopping layer facilitates fabrication of a self-registering electrical connection between the gate electrode and a metallic interconnection line wherever desired.  The thick deposited oxide layer pro-vides reduced capacitive coupling between the insulated regions and the metallic interconnection line when compared to known self-registered gate contacting methods that employ only thermally grown oxide insulation.  The method also includes the provision for controlling the removal of insulation over the gate electrode wherever desired without seriously degrading the insulation over other parts of the structure.  The disclosed method further relates to fabricating an integrated circuit containing FETs having a self-registered electrical connection between the gate electrode and the metallic interconnection line, the gate electrode self-aligned with respect to the source and drain regions, and wherein FETs of the integrated circuit have: a channel region; a gate insulator; an electrically conductive gate electrode; source and drain regions; thick insulation over the source and drain and over the gate electrode except in the contact areas; field isolation or field shield regions between FETs of the integrated circuit; metallic-type high electrical conductivity interconnection line; and self-registering electrical connection between the gate and the interconnection line.

Abstract: ABSTRACT OF THE DISCLOSURE     An apparatus for facilitating the bending and forming of plastic pipe or other devices is provided which includes an elastomer boot capable of expansion and contraction between a first diameter and a second diameter.  The first diameter boot size permits boot insertion into the plastic pipe.  The boot preferably is a tubular structure having a closed first end.          An adapter is mounted along the second end of the boot, which seals the boot to fluid flow, except through the adapter.  The adapter has an axial opening extending through it, which pre-ferably is used to attach a coaxial conduit means to the boot.          After insertion in the pipe, the boot is expanded to its second diameter size, that size conforming to the internal diameter of the pipe.  Means for heating the pipe to bending or forming temperature through the boot also is provided.  After reaching bending temperature, the pipe is bent to the desired shape.          Thereafter, the pipe is cooled by circulating fluid through the boot by way of the conduit means.  The conduit means, in one embodiment, is operatively connected to a hot or cold fluid supply through suitable control means.  After the pipe cools and sets, the boot is returned to its first diameter size and removed.
