A sectional garage door panel includes a skin part formed of a rolled metal sheet forming an outer wall and opposed top and bottom edges which may form a pinch resistant joint when adjacent panels are interconnected. Elongated prefabricated insulation parts are inserted in cavities formed by the top and bottom edges and a generally rectangular planar insulation part is insertable in a cavity formed between the top and bottom edges and between the first mentioned insulation parts. Channel shaped brackets are insertable in cavities formed by the top and bottom edges for reinforcing the skin part at a point of attachment of end stiles and hinge parts. A metal backer sheet forms an inner wall to protect the insulation parts. The brackets and one or more of the insulation parts may be secured to the skin part by an adhesive.

A sectional garage door is formed of rectangular door sections which include hollow extruded plastic rail members interconnected by hollow extruded plastic end and intermediate stile members to form a door section. The rail members and stile members may be fitted with internal tubular or channel shaped metal reinforcing members to minimize deflection of the door sections during use. The door sections may each include an externally fitted strut which is secured to a longitudinal side edge of a section and is connected directly to a reinforcing member disposed within one of the rail members without being forcibly connected to the rail member itself to allow for differential thermal expansion between the rail member and the reinforcing members. Rectangular panel inserts may be removably supported on each door section by removable retainer members and may include insulated panel inserts which may be added to the door sections before or after installation.

An upward acting sectional door is formed of rectangular door sections which are interconnected to each other by a continuous hinge comprising opposed partial arcuate hinge members formed on a lower rail of an upper section and an upper rail of an adjacent lower section and engaged with a third hinge member comprising an elongated tubular pin having a D-shaped cross section. The hinge pin is secured against rotation by retainer members at opposite ends of one of the door sections. The hinge permits lateral assembly and disassembly of one door section relative to the other. Additional load bearing hinge members are provided connected to the lateral side edges of adjacent door sections and are interconnected by support members disposed in the tubular hinge pin for transferring part or all of the forces between adjacent door sections thereby allowing the arcuate hinge members to function substantially as cooperating light and weatherseal members and to provide a substantially pinch proof door.

In a sequence-of-events system for a distributed process control system, unfiltered changes in process element status are initially stored at each remote site along with a time tag. Each remote site has an I/O manager board to which are connected a number of individual I/O boards. Each I/O board in turn has connected to it process signal inputs from a number of process elements (e. g. , 16), which can be in an "on" or "off" state. Each I/O board includes a change-of-state detector to which the process signal inputs are coupled. The change-of-state detector detects a change of state of any process input and generates an interrupt signal, which is coupled to a microprocessor also located on the I/O board. The microprocessor reads the status of all the process element inputs coupled to the scanner and also the output of a local clock on the I/O board. The microprocessor records in a sequence-of-events memory on the I/O manager board the status of all process signal inputs to the change-of-state detector at the time of a change in any input, along with the relative time at which the change occurred.

An industrial control system is disclosed in which various on/off or other binary functions of an industrial process are each controlled by a separate single board computer. Each single board computer is provided with a simplified system whereby the user can interconnect a logic system between input ports and output ports of the computer to control the setting of the binary data at the output ports in accordance with the selected logic system in response to the data applied to the input ports with the output ports being connected to control the on/off and binary functions in the system. The logic functions are implemented in each single board computer by use of an applications program and a patch panel program. In the applications program, the system responds to input data in a flag memory and sets output flags in the flag memory in accordance with each possible logic function that might be used in the system. In the patch panel portion of the program, the input flags are set and the data at the I/O ports are set in accordance with connection specified by the storing of specific addresses in a patch panel memory.

An industrial control system in accordance with the present invention is provided with a plurality of diverse controlled devices (e. g. , fans, pumps, valves, solenoids, relays, etc. ) for effecting overall system control. Each device has a unique set of logic control functions and/or command sequences and is connected, through an input/output interface, to a stored-program single board computer that provides device control and monitoring. The computers each include a central processor controlled by a composite or "master" program which is common to all the computers and which includes instruction sequences for all logic control functions and command sequences that exist within the system. A user alterable interconnection device (UAID) permits only those logic control function and/or command sequence portions of the master program that relate to a particular one of the controlled devices to operatively connect with the particular input/output ports associated with that controlled device. As the master program successively loops, only those logic control functions and/or command sequences that relate to the particular controlled device, as determined by the user alterable interconnection device, are operative to address the input-output ports associated with the controlled device and thereby effect device control and monitoring.

A vehicle restraining apparatus is disclosed which is adapted to be disposed adjacent a fixed structure, such as a loading dock, for securing a vehicle adjacent the fixed structure. In a typical application, the apparatus is disposed adjacent a loading dock for restraining trucks which are backed into a position adjacent the dock during loading and unloading operations. The apparatus includes an articulated structure adapted to be deployed in a vehicle-engaging position adjacent an upright surface of the dock for engaging an adjacent vehicle. The articulated structure includes upper and lower vertically aligned pivot arms, and an actuator is provided for pivoting the upper arm upwardly in a first pivotal direction about a pivot axis substantially perpendicular to the upright surface, and pivoting the lower arm, about a second pivot axis spaced from the first axis, in a second, opposite pivotal direction, the distal end portion of the upper arm being thereby brought into engagement with a structural portion of the vehicle. In a preferred embodiment, a keeper member is mounted on the distal end portion of the upper pivot arm, the keeper member being positioned to seat in front of a horizontally-extending structural member of a vehicle, for securing the vehicle. In a preferred embodiment, the pivot arms of the articulated structure are pivotable about respectively different pivot axes extending substantially horizontally, for maintaining the keeper member in a vertical orientation.
