    • An exhaust duct orifice adjustment device for a gas-fired heater used to indirectly heat an oven communicating with a heat exchanger, wherein the exhaust duct includes a fixed annular orifice plate and a switch having a pressure sensor on opposed sides of the fixed orifice plate, turning off the burner if the pressure drop falls below a predetermined minimum. The orifice adjustment mechanism includes a moveable plate upstream of the fixed orifice plate having an opening communicating with the opening in the fixed orifice plate and an adjustment mechanism moving the orifice adjustment plate from a retracted position, wherein the opening through the fixed orifice plate is substantially unobstructed, to an extended position which restricts the opening through the fixed orifice plate, thereby adjusting the pressure drop.
    • 一种用于间接加热与热交换器连通的烤箱的燃气加热器的排气管孔调节装置,其中排气管道包括固定环形孔板和在固定孔板的相对侧上具有压力传感器的开关, 如果压降低于预定的最小值,则关闭燃烧器。 孔口调节机构包括在固定孔板上游的可移动板,其具有与固定孔板中的开口连通的开口和调节机构,该调节机构使孔板调节板从缩回位置移动,其中通过固定孔板的开口基本上 无阻塞地延伸到限制通过固定孔板的开口的延伸位置,从而调节压降。

    • A self-attaching fastener which may be formed by cold heading having a body including generally arcuate side faces and planar end faces, a central tubular pilot having a planar annular end face, a primary bearing surface surrounding the pilot and arcuate flanges extending from the side faces having planar surfaces spaced below the pilot end face, wherein one or both faces of the pilot and the flange portions facing the pilot are inclined. In one embodiment, the arcuate flange portions each comprise arcuate segments, preferably having inclined opposed surfaces, or the arcuate flanges may be continuous including an arcuate conical midportion and linear inclined side portions. Antirotation tabs may be integrally struck from either the pilot or the flanges.

    • A prefillable delivery device fro administering intradermal injections includes a prefillable container adapter to store a substance. The substrate is expelled through a needle cannula having a forward tip adapted to administer the intradermal injection. A limiter surrounds the needle cannula having a generally flat skin engaging surface extending in a plane generally perpendicular to the needle cannula. An insert is centrally located within the skin engaging surface and is piercable by the forward tip. A sleeve with a first end and a second end surrounds the prefillable container. The limiter is slidably inserted through the first end and the second end is affixed to a depressable pluger for expelling the substance form the container. The limiter is movable between a first position and a second position thereby exposing the forward tip an is selectively movable between a third position and a fourth position thereby concealing the forward tip.
    • 用于皮内注射的预填充递送装置包括用于储存物质的预填充容器适配器。 基底通过具有适于施用皮内注射的前端的针插管排出。 限制器围绕针管,其具有在大致垂直于针插管的平面中延伸的大致平坦的皮肤接合表面。 插入件位于皮肤接合表面内的中心位置,并且可由前端刺穿。 具有第一端和第二端的套筒围绕可预装容器。 限制器可滑动地插入第一端,并且第二端固定到可压下的抽吸器上,以从容器中排出物质。 限制器可在第一位置和第二位置之间移动,从而使前端尖端可以在第三位置和第四位置之间选择性地移动,从而隐藏前端。
