Abstract: A smoke tube for a chimney, which is made of several sections (1) fitted sealingly into one another at their joints. Each section (1) is shaped at one end into a widening socket (2), into which the other end (3) of each section adjoining it above can be fitted with play. A nonwoven or woven fabric (5) of ceramic fibre is sealingly arranged between the inner wall (4) of the socket and the outer wall of the other end (3). The ceramic material (5) can be fixed to the inner wall (4) by adhesive bonding. By inserting the end (3), the previously thicker ceramic material is compressed, resulting in an adequate fixation and a flue-gas sealing of the junction. <IMAGE>

Abstract: In the method according to the invention, the direction of the subsequent scanning is first defined by means of information items which are contained in the object to be evaluated. The detector array used for data pick-up is then rotated in such a manner that its detector rows are perpendicular to this direction of scanning. This choice of scanning direction can be automatic or interactive. For the actual data pick-up, the object is moved in the scanning direction defined in strip-form over the stationary detector array. The signals generated by the detector array during this process are evaluated in a subsequent processor.

Abstract: An extrusion die assembly is provided for making honeycomb structures of ceramics, glass, and other extrudable materials. The assembly is provided with an apertured, flow controlling forming plate (44) placed against the input (upstream) surface of the extrusion die (12). The forming plate has a central opening (50) through which the batch material to the input face of the die passes. A series of angularly spaced, flow controlling openings (46) lies radially outwardly of the rim of this central opening. These forming plate openings are axially aligned with a shim reservoir (30) downstream of the discharge slots of the die. This arrangement permits both the flow volume and rate of the batch material being extruded to the skin forming portions of the die assembly to be at least partially independently controlled relative to the flow volume to the main, radially central portion of the extrudate. By this construction, the formation of air checks in the shim reservoir and the formation of rippled skin on the extrudate is inhibited.

Abstract: An electrophotographic copying machine which forms an electrostatic latent image on a photoconductive means by charging the image forming surface of the photoconductive means by a charger and scanning the charged image forming surface of the photoconductive means by an exposure unit, develops the electrostatic latent image by a developing unit, and transfers the developed image from the photoconductive means to a recording sheet by a transfer unit. The electrophotographic copying machine is provided with a holding means capable of holding an exposure unit of either of different systems. Thus, the electrophotographic copying machine can be constructed in a desired model by incorporating an exposure unit of a desired system without changing most of the component parts.

Abstract: A laminate of two metal sheets (9,10) and a layer of thermoplastic material is made by moving the two sheets (9,10) along respective paths so that they approach each other at a region of convergence and feeding extruded thermoplastic material into the region of covergence so that the material is squeezed between the converging sheets to form the layer adhering to said sheets. To improve bond strength, and reduce bonding time, an extruding nozzle for the thermoplastics material of slot shape is located relative to the region of convergence so that a body (7) of said thermoplastics material in flowable state is formed in the convergence region in contact with the sheets (9,10), the layer being continuously drawn from the body (7) and the body (7) being replenished by extrusion from the nozzle (5'). The body (7) is wider than said extrusion slot as seen in section in the width direction of the slot.

Abstract: A microwave heating system is disclosed which is especially useful for rapidly, uniformly and positively sterilizing biological media, such as broths and gels used as incubation or growth media for bacteria, which system includes a source of microwave radiation, a microwave chamber, a container or a plurality of containers in the chamber, and mixing means for mixing contents of the container or containers during heating thereof, which mixing means are at least partially external to the container and are capable of operating when the container is positively sealed to prevent contamination of the contents thereof. The mixing means is preferably a combination of an external magnet and a mixer which is at least in part of magnetic material (material responsive to a magnetic field) and is moved by changes in the magnetic field set up by the magnet, as the container and contained mixer are moved with respect to the magnet, as on an oscillating turntable. 
     Other means for mixing the material in the container are also within the invention, although they are not as satisfactory as the magnetic means described, and such other means include mechanical means, such as solenoid activated cores or extensions thereof for pushing vertically against a turntable and thereby moving it out of its normal horizontal plane, cam means for accomplishing the same purpose, means for causing the containers to swing, in pendulum-like motion, as they are rotated, and ultrasonic means. 
     Although the described system is ideal for sterilizing biological media, which may be in sealed containers and protected from contamination, and which may be positively sterilized, under pressure, as is often desirable, more efficient and faster microwave heatings are also obtainable for other operations, such as digestions, chemical reactions, dryings, analyses, and preparations of materials for analyses. 
     Also, the invention may be utilized for mixing without microwave heating.

Abstract: Partially recessed microlenses (31, 32;) are made in a substrate (10) by a technique including the steps of forming a hard-baked patterned layer (21, 22, 64) on a surface of the substrate, this patterned layer having at least one island portion (21, 22) surrounded by an auxiliary portion (64), and simultaneously etching this hard-baked patterned layer and the substrate to remove at least a portion of the thickness of the hard-baked layer. The island portions are located at areas overlying where microlenses are desired. The volume of the auxiliary portions of the hard-baked patterned layer is advantageously significantly greater than that of the island portions. 
     Fully recessed microlenses are made by adding a step in the above technique, namely, the step of forming another hard-baked patterned layer covering only the auxiliary portions (64) of the above-mentioned patterned layer prior to the etching.

Abstract: A method for heat processing a superconductor wire (11) which has a protective silver cladding (26) includes the steps of attaching the coated wire (12) to a spool (60) and then rotating the spool (60) to wind the wire (12) around the spool (60) in juxtaposed coils (70). As the wire (12) is being wound around the spool (60), the portions of the wire (11) which are not yet coiled are drawn through a container (34) which holds a paint (38) that contains a silver diffusion inhibiting material. The diffusion inhibiting material is consequently deposited onto the silver cladding (26) of the superconductor wire (11), and the coiled wire (12) is subsequently placed in a furnace (74). The wire (12) is heat processed in the furnace (74) as appropriate for the particular type of superconductor material. The diffusion inhibitor material prevents diffusion of silver during the heat processing between portions of the wire (12) which contact each other.
