Abstract: The present machine is intended for the printing of selected characters on labels borne by a continuous tape (13) passing over a print table (11) and driven by a chassis (22) imparted a reciprocating movement by the operating of a trigger. In order to prevent the strip of labels from being pulled towards the outside at the time of the pulling off of the label said machine has a hand brake (28, 30) located in front of the print table. This brake comprises a pivoting brake shoe (28) which is placed out of operation during the transport stroke of the continuous strip (13) by an interceptor (32) which is fastened to the transport chassis (22). This arrangement is established in order to permit a precise and effective braking action without requiring recourse to tolerances which are incompatible with mass production.

Abstract: In an electrolytic reduction cell for the production of molten metal, particularly aluminium, by electrolysis of a less dense salt a monolayer of ceramic shapes is located on the floor of the cell. Such shapes are formed of a ceramic material, wettable by molten aluminium, but not wettable by the cell electrolyte. The spacing between adjacent shapes and/or the apertures in individual shapes is selected such the interfacial surface forces prevent entry of electrolyte between the shapes. The shapes may be tiles, honeycombs, cylinders, tubes, balls etc. The product metal may be collected in a sump for periodic withdrawal from the cell or withdrawn continuously or at short intervals through a selective filter that permits passage of molten metal, but not of molten cell electrolyte, at low withdrawal rates.

Abstract: A method and apparatus for photon scanning tunneling microscopy for examining a sample in a sample area on a surface at a subwavelength resolution is disclosed. The method comprises generating a near-field of photons at a surface containing a sample area. The near-field has an area that is larger than the sample area, and the near-field has an exponentially increasing intensity in a direction perpendicular to and towards the surface. The near-field is sampled with a probe which receives photons from that near-field that tunnel from the surface to the probe. The received photons are detected and a detector produces an output signal that is proportional to the number of photons received by the probe. The sample area is scanned with the probe in at least one direction parallel to the surface. While scanning, the probe may be maintained either at a position of a constant near-field intensity or at a position of constant distance from the surface. A photon scanning tunneling microscope for using the method is also disclosed.

Abstract: A rotary kiln having a polygonal lining is disclosed for pyro-processing cement, lime, other minerals, as well as other materials. Specifically, utilizing a polygonal lining of a refractory or ceramic material having between 3 and 12 sides improves the heat efficiency or heat transfer between high-temperature gases and a burden of material to be processed by the kiln. Such an efficient utilization of the gas heat is due to various factors which cause a larger amount of the burden to be more quickly exposed to the high temperature gases. These various factors include increased tumbling, increased residence time, decreased degree of filling, and increased surface exposure.
