Abstract: Improved compositions for use during shaving of hair are disclosed as well as methods that employ such improved compositions for shaving. These improved compositions and methods may help to reduce irritation of skin during shaving, reduce irritation of skin after shaving, increase the lifetime of razors used for shaving and/or decrease the quantity of composition needed for each act of shaving.

Abstract: An improved buster point assembly is disclosed. The improved buster point assembly has an elongated shaft attached to a replaceable tip. The replaceable tip includes a working end and a connecting end, the connecting end has a chamber for receiving a distal end of the elongated shaft.

Abstract: A rotary drill bit for drilling a hole through a solid body is disclosed. The drill bit includes a collar and a penetrating member. At a proximal end, the collar is attachable to a drill shaft. At a distal end, the collar is attachable to the penetrating member. The penetrating member has a connecting end for attachment to the collar and a cutting end for engaging the solid body. A pilot drill is fixedly attached to the cutting end for initiating contact with the solid body.

Abstract: A drill bit shaft member for tapping a hole in a blast furnace is disclosed. The drill bit shaft member comprises an elongate rod, a first fluid pressure inlet, a second fluid pressure inlet, a chamber in fluid communication with the first fluid pressure inlet and the second fluid pressure inlet, and an outlet in fluid communication with the chamber. A liquid and a gas are combined in the drill bit shaft member to form a mist to provide cooling for the drill bit shaft member. By cooling the drill bit shaft member, certain components that would normally be destroyed may be re-used.

Abstract: A drill shaft assembly for a blast furnace taphole-opening system includes a drill shaft adapted for receipt of a drill bit at its forward end and for coupling with a hollow drill tool piece at its rearward end. The drill shaft has a solid cross-section along substantially its entire length and is provided, beginning at its rearward end, with an air channel which is in communication with a source of pressurized air for clearing dust from the taphole as it is being drilled. A coupling means is provided so that the drill shaft may be detachably attached to the drill tool piece shaft so that it is readily replaceable.

Abstract: An emission control system for controlling the emissions released from the pig iron and slag released from a blast furnace and through the troughs in a casthouse. The system comprises tap hole cover means for covering the first end of the main iron trough and for evacuating emissions from the pig iron and slag flowing through the first end of the main iron trough. The tap hole cover means in flow communication with scrubber means for cleaning emissions. Removable cover means for covering the second end of the main iron trough and for evacuating emissions from the pig iron and slag flowing through the second end of the main iron trough. The removable cover means in flow communication with scrubber means for cleaning emissions. Main iron runner cover means for covering the main iron runner to prevent the escape of emissions into the ambient air. Slag runner cover means for covering the slag runner to prevent the escape of emissions into the ambient air.

Abstract: A method and device for indicating alignment of a pair of headlights. A pair of elongated members are removably mounted by suction cups to the forward-looking faces of a pair of headlights. Each elongated member includes a sight-line scope which is used to visually observe a lateral aim mark on the elongated member mounted to the opposite headlight. The vertical aim of each headlight is adjusted until the bubble levels on the members are properly centered. The lateral aim of each headlight is adjusted until the lateral aim mark on one elongated member is properly centered relative to the sight-line scope provided on the opposite elongated member.
