Moreover the apparatus is less expensive than the known removal apparatus.

Abstract: A plunger, having an oblong body with a front end and a rear end and a lancet having a pointed end section projecting axially from said body at the front end, is insertable in a cylinder having an oblong hollow body with a front end, a rear end and an axial hole. The cylinder is at least elastically distendible in the radial direction adjacent its rear end. The plunger is of such a length and the lancet is so arranged that the pointed end section of the lancet protrudes a predetermined distance out of the cylinder at the front end when the plunger is fully inserted in the cylinder thereby defining an operative puncturing position. The plunger and cylinder have a first engaging stop arranged after partial insertion of the plunger, to temporarily prevent continued insertion at a predetermined initial position.

Abstract: A counterflow separator is provided having a feed pipe for bulk material opening into the top of a chamber housing. A discharge conduit radial extends from the top of the housing and an inlet conduit for classifying air extends radially into the housing at its lower portion. The housing is provided with a wall section below the orifice of the feed pipe, which section expands conically outwardly into a collecting hopper. The conical wall section permits the design of a braking stretch longer than its own length, thus reducing the requirement for classifying air, without causing a deterioration in the classifying quality.

Abstract: A transport conduit for bulk material is formed of a rigid outer tube and an elastic inner tube of substantially smaller diameter. The inner tube is hermetically sealed at each of its ends to the conduit section so as to form a closed annular chamber between the inner elastic tube and the rigid outer tube. Communicating through the wall of both the outer and inner elastic tubes are relief and check valves sealed with respect to the elastic inner tube so as to maintain the integrity of the annular chambers. The valves are connected to a secondary gas supply from which air under pressure is directed into the conduit to assist in the transport of the bulk material. The annular chambers are serially connected by bridging tubes passing from one section to the adjacent section, thereby interconnecting each of the annular chambers in an outer parallel conduit to permit atmospheric air to move serially through them from one end of the transport conveyor to the other.

Abstract: A plunger having an oblong body with a front end and a rear end and a lancet having a cutting edge projecting axially from said body at the front end is insertable in a cylinder having an oblong hollow body with a front end, a rear end and an axial hole. The plunger of such a length and the lancet is so arranged that it protrudes a predetermined distance out of the cylinder at the front end when the plunger is inserted thereby defining an operative cutting position. The plunger and cylinder have first engaging stop means arranged after partial insertion of the plunger, to temporarily prevent continued insertion at a predetermined initial position. The arresting function of the stop means is overcome by applying pressure on the plunger thereby pushing it the remaining distance into the cylinder from the initial position to the operative position.

Abstract: In a method of manufacturing silica-free, interconnected porous ceramics, use is made of ceramic material powder which exhibits an expansion phenomenon due to reaction when fired; the ceramic material powder is mixed with binder; the mixture is molded; thereafter the molded mixture is fired and, during the firing process, held for a predetermined period of time at a predetermined temperature which is not lower than a temperature at which maximum expansion occurs in the expansion phenomenon but lower than a temperature at which the firing of the molded mixture is completed; and the firing process is stopped after a lapse of the predetermined period of time.
