Appl. No.:

11/600469

Inventors:

Jason Cheng - Brooklyn NY, US
Kok Ki Tam - Brooklyn NY, US

International Classification:

F24C 15/20

US Classification:

126299 D

Abstract:

A device and method for cleaning fans in range or stove hoods by spraying steam onto the fan impeller area on which soot and cooking fumes condense to clean the impeller and wash the accumulated condensates down a drain. By using steam above atmospheric pressure as the cleaning fluid, the device uses significantly less water that other devices that spray water or an aqueous solution to clean the fan blades.

International Classification:

F41C 23/16
F41A 5/26

Abstract:

A free float handguard for a firearm having a barrel includes a handguard body and a locking arrangement. The locking arrangement includes a barrel locker and a handguard locker. The barrel locker includes a first tubular locker adapted for coaxially coupling at a fixed end of the barrel, and a second tubular locker coaxially and rotatably coupled at the first tubular locker. The handguard locker has a rear portion coaxially coupled at the first tubular locker to prevent the handguard locker from being rotated therearound, and a front portion engaged with the second tubular locker to prevent the second tubular locker from being rotated around the first tubular locker, wherein a first end portion of the handguard body is coupled at the handguard locker for locking up the handguard body around the barrel in a free float manner.

Assignee:

NcSTAR, Inc. - City of Industry CA

International Classification:

F41C 27/00

Abstract:

A keymod mount, which is arranged for detachably coupling at a firearm having one or more keymod slots, includes a securing member and a locking member movably extended from the securing member. The securing member includes a mounting body having a top utility surface, and a coupling head downwardly extended from a bottom surface of the mounting body for slidably engaging with a narrow slot portion of the keymod slot to retain said mounting body on a top surface of the keymod slot. The locking member includes a locking body and a locking head downwardly extended from a bottom surface of the locking body for inserting into an enlarged slot portion of the keymod slot after the coupling head is engaged with the narrow slot portion thereof, so as to securely lock up the securing member on the firearm.

International Classification:

F41G 1/34

Abstract:

A sight device includes a mounting base for detachably mounting on the firearm, a sight unit upwardly extended from the mounting base, and a sight arrangement provided at the mounting base at a position underneath the sight unit, wherein the sight arrangement includes first and second modules. The first sight module includes a first light housing frontwardly extended from the mounting base and a first light unit supported in the first light housing for generating a light beam parallel to a bore axis of the firearm and close to the bore axis of the firearm to reduce an off-axis bore height. The second sight modules includes a second light housing frontwardly extended from the mounting base and spaced part from the first light housing, and a second light unit supported in the second light housing for illumination.

Abstract:

A scope includes a scope assembly and a head lighting arrangement. The scope assembly includes a tubular scope body having an objective end and an opposed sight end to define a scope axis, an objective lens and an eyepiece lens supported at the objective end and the sight end of the scope body respectively for generating a scope reticle, and an attachment base extended from a bottom side of the scope body for detachably mounting the scope body on the firearm to parallelly align the scope axis with a barrel axis of the firearm. The head lighting arrangement includes a plurality of illumination elements formed at a rim of the objective end of the scope body for generating navigation light at a direction aligned with the scope axis of the scope body.
