Filed:

Mar 2, 1994

Appl. No.:

8/205049

Inventors:

James C. Swain - Columbus OH
Larry E. Schluer - Sugar Grove OH
Donald L. Cooper - Columbus OH
Alan A. Alten - Baltimore OH

Assignee:

Gas Research Institute - Chicago IL

International Classification:

G01F 320

US Classification:

73268

Abstract:

A compact, 4-chamber gas meter comprising crankpost and valve drive mechanisms whereby each reciprocating valve moves from a stroke shifting point near center to a stroke endpoint and back to said stroke shifting point with each 180. degree. rotation of the crankpost and each stroke of each diaphragm occurs over said 180. degree. rotation of the crankpost.

International Classification:

F04B 4900

US Classification:

417223

Abstract:

A compressor assembly for pumping a recirculating refrigerant including input and output shafts rotatably supported within a housing and a pressure responsive clutch disposed therebetween for selectively translating torque from the input shaft to the output shaft to drive the compressor. An auxiliary clutch compressor is employed for generating an auxiliary refrigerant discharge pressure and a control valve is moveable between first and second positions to either route refrigerant discharge pressure away from the clutch or to bear upon the clutch so as to translate torque between the input and output shafts.

Abstract:

A composition for adhering to human nails includes a mixture of a cyanoacrylate compound and/or graphite fibers. Such composition can take the form of either an artificial nail extender or a nail coating. The composition for forming an artificial nail includes graphite fibers, a cyanoacrylate, and a hardening accelerator containing a mixture of trichlorotrifluoroethane and N,N-dimethyl-P-toluidine. The accelerator is adapted to be sprayed onto a base material containing the graphite fibers and cyanoacrylate in the form of a mist. Nail compositions containing graphite fibers have significantly increased strength yet remain flexible to allow for flexure of the nail. The cyanoacrylate compounds increase the chemical bonding of the compositions to a nail.

International Classification:

A61M 500

US Classification:

604195

Abstract:

A syringe for giving medical injections which has an internal mechanism for retracting the needle into the syringe after the injection has been given and locking the needle and plunger inside the barrel of the syringe to reduce the risk of accidental needle pricks. In one embodiment the needle is retracted by a tension spring into a compartment inside a hollow plunger and in the other embodiment the needle is propelled by a compressed spring into a compartment within the plunger. In both embodiments, the interior of the hollow plunger is hydraulically sealed off by a barrier from the fluid chamber of the syringe to prevent fluid from entering the interior of the hollow plunger.

International Classification:

B05B 308

US Classification:

239215

Abstract:

A portable pump spraying device includes a container for the liquid to be sprayed, a housing positioned above the container having a spraying chamber, a pumping unit to elevate the liquid to the spraying chamber, and a rotating disc in the spraying chamber to attenuate and impel the liquid by centrifugal force through an egress port in the housing. Interceptor baffles within the spraying chamber finely trim the liquid spray as it leaves the egress port and direct the excess liquid back to a reservoir for recirculation. The pumping unit includes a rod that is reciprocated by an eccentric on the rotating shaft on which the disc is mounted. The rod acts as a piston which on its suction stroke withdraws liquid from the container and on its compression stroke discharges the withdrawn liquid and forces it through a nozzle onto the disc in the spraying chamber. In one form of the invention, the volume of liquid being pumped by the pumping unit may be varied for varying the amount of liquid being sprayed without varying the speed of the pump drive motor and thus the speed of the disc driven thereby.
