Granted: 1981-10-27
Abstract: ABSTRACT      In a process and apparatus for the continuous burning of a fuel, the fuel is run into a combus-tion space where it is burnt after being ignited, making use of oxygen-containing gas run into the space. The relation of gas to fuel is changed de-pendent on the adjustment, of a desired oxygen content in the flue gas current. For making certain of an unchanging combustion power, the fuel inlet rate is controlled to be directly dependent on the adjustment of the oxygen content in the flue gas while keeping up an unchanging rate of input of oxygen-containing gas into the combustion space.

Abstract: ABSTRACT A moving element is held without contacts in a relatively stable holding position, out of which it is released by the application of an external force.  The relatively stable holding position is obtained by superimposing a potential field of magnet edges by a further potential field based on a mechanical bias of the moving element or a magnet in such a manner that the curve of the total potential has a trough corresponding to the holding position.  By applying an external force, the moving element is moved to a peak position of the total potential curve, whence it is subject to accelerating forces.      A typical embodiment, characterized by rare earth magnets, is particularly suitable for printers for initially accelerating moving coil operated print hammers.

Abstract: ABSTRACT OF THE DISCLOSURE          The manually actuatable electric switch has a fusible element which melts on subjection to a predetermined temperature to discontinue the flow of electric current through the switch.  The structure is incapable of operation on melting of the fusible element without replacement of the element, thereby preventing, accidental reactivation of the switch prior to termination of the unusual thermal conditions causative of the melting of the element.  A manually operable plunger normally used to open and close the switch is mechanically connected to the stem of the switch through the fusible element.  Melting of the element severs the mechanical connection between the plunger and the switch.

Abstract: CONTACTLESS TURNING GUIDE HAVING AIR SLOTS LONGITUDINALLY ALONG RUNNING WEB EDGES                 Abstract of the Disclosure A guide for contactless support of a running web as the latter changes directions.  The guide is formed as a drum-like member having an arcuately curved surface which can be variable as to the length of its arc depending on the degree of turn or change of direction desired for the running web.  A pair of circumferentially spaced air nozzles extend along the length of the drum-like member and transversely across the web and pressurized air is fed through the nozzles so as to form a pneumatic cushion between the web and the arcuate surface of the drum-like member to thereby float the web in its turning direction over the drum-like member and without contact therewith.  The invention includes a pair of air nozzles, one extending along each side edge of the running web and located out-side the width of the web and which not only retard or eliminate leakage of air from the supporting air cushion out from under the longitudinal edges of the web, but also act on the web to eliminate side drift or lateral tracking instability of the web.

Abstract: 15. DUAL WAVELENGTH OPTICAL ANNEALING OF MATERIALS         Abstract A new mode of radiant heating is disclosed wherein two different wavelength pulses (FIG. 7, 42, 43) are used to melt portions of a solid body (41). The first pulse may be of relatively weak intensity, but is strongly absorbed by the solid. The second pulse, which is not strongly absorbed by the body when in the solid phase, is strongly absorbed by the body when in the molten phase.  Exposure to the first pulse results in an initial melting of the body, which then becomes highly absorptive to radiation at the wavelength of the second pulse. Readily available radiant energy sources, e.g., lasers, which generate radiations generally not highly absorbed by the body in the solid phase may thus be efficiently utilized.

Abstract: ABSTRACT A device is described for stocking flat workpieces, particularly blanks for foldable boxes.  The workpieces are fed through the apparatus as a series of side-by-side streams.  A stream braking and separating mechanism separates a leading section of each stream and brakes the remainder of each stream.  This is followed by a reject mechanism for remaining flawed work-pieces.  After passing the reject mechanism, the workpieces in each stream are stacked, and the stacks are fed to an orientation and transfer device which stands the stacks on edge and feeds them intermittently to a batching device where multiple-stack batches of workpieces are formed.
