Abstract: An anchor and stress plate assembly adapted to secure an insulation layer to the deck of a roof without penetrating the lower surface of the deck which is formed either of relatively soft or hard decking material. The anchor is provided with a flanged head and a shank whose leading section takes the form of an auger screw having a root which tapers toward the tip and a threading about the root whose crests are of approximately uniform diameter. When the anchor is turned into soft decking material, the tapered root of the auger screw then acts to pack this material into a dense mass in the region surrounding the screw to enhance the holding power of the anchor. In hard decking material, a hole must first be drilled therein to receive the auger screw whose root when the anchor is turned in fits within the hole and whose crests then cut a thread in the hole wall to securely retain the anchor.

Abstract: A barrier is constructed from a plurality of cell-like elements interconnected to form a rigid barrier under normal circumstances. The linkages between cells provides a friction-brake force which is exceeded upon application of a traumatic force such as a bomb blast. The linkages includes slots in each cell connecting adjacent cells with prestressed nuts and bolts to permit sliding relative movement between adjacent cells after a predetermined threshold force has been exceeded. A transverse reinforcing rod, having a series of plates along its length, passes through adjacent cells. The plates act as a viscous damper as they move through a filler material within the cells while the rod adds strength. The cells may be coated with a dry lubricant to control the static coefficient of friction. The ability of the cells to move protects the barrier from structural failure by dissipating the blast forces through the frictional work required to displace the cells.

Abstract: A pneumatic control system for the variable area turbine inlet of a turbocharger of an internal combustion engine. The variable turbine inlet is actuated by a pneumatic actuator having a first connection to compressor boost pressure and a second connection to turbine inlet pressure.

As a result, turbine pumping losses during high engine rpm low power conditions are minimized.

Abstract: A method and apparatus for implementing a thermodynamic cycle with preheating, involves expanding a gaseous working fluid to a medium pressure to transform its energy into usable form. The expanded gaseous working fluid is split into two different streams. One stream is further expanded to a spent low pressure level to produce further usable energy. This stream is then condensed. The other of the two streams is used to preheat the condensed stream and is mixed with the condensed stream at a point upstream of the point of preheating. This decreases the irreversibilities in the preheating process and enables greater efficiencies to be achieved.

Cooling of the flame tube is performed by full coverage impingement and effusion without disturbing the cooling film by entry and penetration of transverse air jets. Flame stabilization is achieved under all required operating conditions by the radial-fuel/axial-air atomization in conjunction with the baffle plates. Comprehensive combustion mixing and dilution is achieved by the uniformly distributed supply of up to 90% of the total air supplied to the combustor around and through the baffle plates.

Thermal coupling of the refrigerator to the cryopanels is by means of spring biased thermal contacts brought into position by movement of the refrigerator. The thermal contact elements are provided with sufficiently large thermal masses to handle the large thermal loads of system startup.
