Patent number: 5317884Abstract: A refrigerant precooler device, connecting into the Freon line of an existing air conditioning unit, and directing this freon through a finned cooling coil, and having a downdraft fan blowing air downward onto a supply of water in the bottom of the precooler device, and the fan blades being surrounded at a strategic location by a venturi shroud, which tends to disperse some of the air from the fan outward, and over the fins of the cooling coil, thereby causing an accelerated evaporation effect, with the added cooling of the Freon. A controlled supply of water in a reservoir at the bottom of the device is pumped upwards through a tubing device and into a pipe which is located onto the top of the cooling coil, and the pipe has a slot cut lengthwise of its bottom longitudinal dimension, and the pumped water drips out of the slot in the pipe, and drains downward over the fins of the cooling coil.Type: GrantFiled: October 26, 1992Date of Patent: June 7, 1994Inventor: Robert J.

Patent number: 5301469Abstract: A counterbalanced door assembly particularly suited for heavy-duty load bearing applications such as sidewalk access doors, and for precasting into concrete slabs, comprises a door, a frame surrounding the door, a hinge connecting the door to the frame for rotation about a first axis, a torque rod arm mounted to rotate about a second axis displaced from the first axis, and one or more torque rods. One end of the torque rod arm is connected to the torque rod to twist the torque rod as the torque rod arm rotates about the second axis thereby generating a counterbalance force. A force control mechanism, which may be a cam with a properly shaped cam surface or a link hinged at either end, receives the counterbalance force from the torque rod arm and applies it in a controlled direction over a controlled effective moment arm relative to the first axis to generate the desired counterbalance torque.Type: GrantFiled: January 8, 1992Date of Patent: April 12, 1994Assignee: The Bilco CompanyInventor: Robert J.

Patent number: 4970958Abstract: A control system for a magentic submarine mine adapted to be fired automaally upon the approach of a vessel and in which the possibility of premature detonation of the mine by a minesweeper is substantially reduced. For example, some of the magnetic mines being laid in a particular mine field may be set so that after several actuations by a minesweeper a few of the mines will be exploded, the remaining mine field requiring a larger number of signals before detonation. By varying the number of signals before a mine is detonated the particular mine field after being swept is still considered lethal because many of the mines are left in the armed condition and others awaiting to be armed by subsequent minesweeping or the passage of vessels, as the case may be.Type: GrantFiled: December 31, 1962Date of Patent: November 20, 1990Assignee: The United States of America as represented by the Secretary of the NavyInventors: Robert J. Lyon, Richard L. Lorenz, deceased

Patent number: 4720426Abstract: A multilayer film for coating an exterior of a scintillation detector bar includes a pressure sensitive adherent layer containing a percentage of a light-diffusing material therein for affixing to an external surface of the bar. A clear plastic layer separates the adherent layer from a specularly reflecting layer. A protective layer is disposed atop the specularly reflecting layer. The light-diffusing material and the specularly reflecting layer cooperate to retain light within the bar, direct light in random directions within the bar and block optical crosstalk between adjacent bars. A preform consisting of a single piece of film may be used for covering five sides of the bar.Type: GrantFiled: June 30, 1986Date of Patent: January 19, 1988Assignee: General Electric CompanyInventors: August O. Englert, Robert J. Lyons, Charles F. Marks

Patent number: 4145843Abstract: A cup-shaped support member for a lift-cylinder in a horizontal door structure, such as a hatchway, in which the lift-cylinder counter-balances the weight of the door. The base of the lift-cylinder is pressed against the bottom of the cup by its spring in the usual manner, and tilts about a flange on the foot as the door is swung open or closed. One or more clean-out holes are provided in the cup bottom, and an inturned lip is formed on the edge of the cup so that it overlaps the flange on the foot of the lift-cylinder. Foreign matter, such as dirt or ice, which heretofore has built-up under the foot of the lift-cylinder until the foot of the cylinder is lifted out of the cup, is forced through the clean-out holes in the support cup by engagement of the lip with the flange on the cylinder foot, preventing it from being lifted off the bottom of the cup while still allowing the cylinder to tilt freely.Type: GrantFiled: April 27, 1978Date of Patent: March 27, 1979Inventor: Robert J. Lyons

Patent number: 4135508Abstract: A metal stairway stringer with horizontal slots at each tread level, into which the treads are inserted laterally for supporting them at one end, the other ends of the treads being similarly supported in like manner by a second stringer. The slots for the treads each taper from adjacent the open end at the edge of the stringer toward the back, so that the treads must be wedged into position and are therefore held rigidly by the stringer.Type: GrantFiled: November 3, 1977Date of Patent: January 23, 1979Inventor: Robert J. Lyons

Patent number: 4104761Abstract: Mounting means for a door-check for a hatchway door hinged to swing between an elevated open position and a closed position and having torsion bars which serve not only as springs for counterbalancing the weight of the door, but also as the hinge pins for the door. Each torsion bar has a terminal portion which is bent backwardly into parallel relation with a straight portion, the terminal portion extending through the hinge and forming the hinge pin. The straight portion is secured at its other end to the hatchway frame and is twisted about the terminal portion by the hinge as the door is closed. The door-check member is mounted on the hatchway frame and is connected to a bracket mounted across the crook formed in the torsion bar where the terminal portion bends backward. The bracket therefore pivots about the hinge pin with the main portion of the torsion bar when the door is closed and provides a crank arm for actuating the door-check.Type: GrantFiled: July 13, 1977Date of Patent: August 8, 1978Inventor: Robert J.
