Abstract: ABSTRACT          This is an inovation dealing with the structural enclosing of space by the use of prefabricated or preformed panels assembled in an edge to edge relationship to form enclosing surfaces of either flat or approx-imated curve (simple or compound) in such a manner as to provide a hollow box section or duct that extends and communicates along all edges of said panels on assembly.  A characteristic of this box sect-ion so formed is that one or more sides of the section so formed are removable without affecting the structural strength detrimentally. The advantages of this structural form are twofold, the ducts so formed are a contributant to structural strength due to their box section and because of their design (one or more removable plate sections) they provide the unique feature of allowing changes to be made in the services therein contained (electrical, plumbing, heating and air-conditioning) without costly structural modification or change.  A structure so constructed has increased adaptability to need, increased versatility and a marked reduction in maintenance costs generated by the normal servicing of utility or service systems due to the provided access to the entire distribution within the structure.   1.

Abstract: ABSTRACT OF THE DISCLOSURE                  A door operator mechanism includes a spring biased piston 5 having a non-return valve 6 in its end face slidably disposed in a hydraulic cylinder 3 and coupled to a door lever arm through a pinion shaft 11, a pinion gear 9, and a tooth rack 7 on the piston.  If the door is opened beyond a normal angle a rod member 16 disposed within the spring 4 engages and compresses a resilient member 15 disposed between one end of the cylinder and the spring.  The resilient member has a higher coefficient of resiliency than the spring and thus is not initially compressed thereby, and its restraining force increases sharply at high compression ratios, to thereby increasingly resist door overtravel.

Abstract: Abstract of the Disclosure A thermostatically controlled clutch assembly, e.g. for use in an automobile for coupling the cooling fan to its drive shaft, comprises a non-rotatable support shaft, an annular output member journalled for rotation about the support shaft, and an annular input member journalled for rotation about the support shaft and the output member.  An annular actuating cylinder and piston assembly is journalled for rotation about the support shaft and connected for rotation with the input member, clutch driving plates being connected for rotation with the actuating cylinder and piston assembly and clutch driven plates being connected for rotation with the output member. First passage means within the support shaft conduct pressurised fluid from an external source to the actuating cylinder and piston assembly, and second passage means within the support shaft conduct a supply of cooling and lubri-cating fluid from the external source to the clutch driving and driven plates. Both the actuating fluid and the cooling and lubricating fluid are commonly drained from the clutch assembly for return to the external source.  A control valve has a temperature sensing element arranged to open the valve to admit pressurised fluid to the first passage means at and above a predeter-mined temperature ambient to the sensing element to actuate the clutch and establish a driving connection between the input and output members, and to close the valve when the temperature ambient to the sensing element is below said predetermined temperature to deactuate the clutch.  In all cases, a supply of pressurised fluid is arranged to be continuously coupled to the second passage means for supplying the cooling and lubricating fluid.
