Abstract: A terminal and gauge assembly which provides connections for lines to or from individual fluid pressure circuits, such as the pneumatic circuits of a pneumatically operated control system includes a duct with a removable cover. The lines run longitudinally inside the duct. A bar located on the cover outside of the duct is formed with spaced chambers. The lines are terminated at couplings which extend into the chambers and serve to fasten the bar to the cover of the duct. Gauges or test points are mounted on the bar and connect to the chambers so that the pressure or other parameter associated with each circuit may be monitored.

Abstract: The efficiency of an environmental control system such as a heating, ventilating and air conditioning system is enhanced and energy is conserved by starting and stopping the heating or air conditioning modes of operation at variable times at the beginning and end of an occupancy period, which times are a function of an environmental condition, such as outside temperature in the case of heating and inside temperature in the case of air conditioning. To this end a control system is provided which generates an output for initiating and terminating the operation of the conditioner. Separate intervals during which the generation of the variable output for initiating the operation of the conditioner and for terminating the operation thereof are established as by means of an arrangement of cams driven by a timer motor which runs during these intervals.

Abstract: A chassis lock to secure a container body to a trailer chassis includes a bolt comprising upper and lower telescoping sections, the upper section having a head member received in a cavity in the container body and shaped so that rotating the head bolt locks the body to the chassis. The head member is rotated through the lower portion which is vertically displaceable and lockable in two rotatably different positions by a plate welded thereto that locks into a slot in the chassis in those two positions.
