US Patent:

44423799, Apr 10, 1984

Filed:

Jul 30, 1982

Appl. No.:

6/403900

Inventors:

Robert G. Frey - Strongsville OH
Charles I. McVey - Shaker Heights OH

Assignee:

General Electric Company - Schenectady NY

International Classification:

H05B 4116
H01J 6156

US Classification:

315 47

Abstract:

An improved high pressure sodium vapor lamp is described having resistance heater means contained within a tubular light-transmitting ceramic envelope that further contains a reservoir of sodium-mercury amalgam in excess of the quantity vaporized during lamp operation in order to increase the quantity of amalgam being vaporized during lamp operation and thereby help maintain the desired lamp color temperature. In a preferred embodiment, said resistance heater means comprises a refractory metal coil wound around the tungsten shank of one thermionic electrode and electrically insulated therefrom with said thermionic electrode including a tubular metal inlead serving as the amalgam reservoir.

Appl. No.:

8/249339

Inventors:

Robert A. Frey - Westlake OH

Assignee:

HMI Industries, Inc. - Cleveland OH

International Classification:

B01D 4602

US Classification:

55309

Abstract:

A vacuum cleaner filter bag having multiple, nested inner bags and an outer bag for sequentially filtering a discharge from a vacuum cleaner, wherein each of the inner bags is adapted to cease filtering the discharge therethrough when the bag has become clogged with particulate matter. Each inner bag is designed to rupture, when clogged, in a manner to allow the discharge to bypass that bag and directly enter the next bag.

Appl. No.:

8/224693

Inventors:

Robert A. Frey - Westlake OH

Assignee:

HMI Industries Inc. - Cleveland OH

International Classification:

A47L 536

US Classification:

153272

Abstract:

A vacuum cleaner is provided comprising a canister including a chamber with an air inlet, an electric motor and a fan driven by the motor. The fan creates a vacuum in the chamber drawing air in a path from an air inlet through a filter located in the chamber, and out an air outlet. The vacuum cleaner includes a platform base, the base being detachable from the canister by a VELCRO fastening system.

Assignee:

HMI Industries, Inc. - Cleveland OH

International Classification:

B03C 3155

US Classification:

96 69

Abstract:

A vacuum cleaner having a reduced velocity chamber with a high velocity air inlet, an electric motor, a rotary mechanism driven by the motor for creating a vacuum in the chamber, an outlet for exhausting air from the chamber, which air flows in a selected path from the air inlet, through the chamber and out the air exhaust outlet and a disposable porous sheet filter layer in the chamber for removing solids particles from the air. The vacuum cleaner also has a fiber filter between the filter layer and the motor where the fiber filter has an electrically charged non-woven material for removing very fine air particles in the chamber, intersecting the air path and generally coterminous with the disposable filter layer.

International Classification:

H05B 4116

US Classification:

315 47

Abstract:

An improved high pressure sodium vapor lamp is described having resistance heater means contained within a tubular light-transmitting ceramic envelope that further contains a reservoir of sodium-mercury amalgam in excess of the quantity vaporized during lamp operation in order to heat the ceramic envelope before lamp starting and thereby reduce the starting voltage requirements. In the preferred embodiment, said resistance heater means comprises a refractory metal coil wound around the tungsten shank of one thermionic electrode and electrically insulated therefrom and which is supplied with lower current than is subsequently applied to said electrodes for the lamp operation.

Inventors:

Robert A. Frey - Westlake OH

Assignee:

HMI Industries, Inc. - Cleveland OH

International Classification:

B01D 4600

US Classification:

55368

Abstract:

Vacuum cleaner canisters and vacuum cleaner filter bags are provided with weir members disposed in the path of particle laden air flowing through the vacuum cleaner. The particle laden air flows across the top and/or side edges of the weir members creating a pressure drop thereacross and an area of low pressure on the downstream sides of the weir members whereby particles in the airstream are influenced to drop out of the airstream and into the low pressure areas.
