Patent number: 4925473Abstract: Control of speed and uniformity of the heating of the working zone of the preform in a glass drawing operation in which the softening heat is applied by forced convection (13), using a separate fluid heating zone to introduce temperature and velocity controlled fluid. The size of the working zone is further controlled by changing (18) the configuration of a movable exit sleeve. Uniformity and accuracy of temperature is enhanced by normalization (10) of the temperature of the preform close to a preselected value before the preform enters the furnace. A glass drawing apparatus embodies the preferred means to carry out the process, providing a two-chamber furnace having an air heating chamber (44) connected by air delivery channels (51) to a drawing chamber (43). The drawing chamber has preform inlet (41) and a drawn product outlet (56). Each of the latter preferably has an adjustable opening diameter. The inlet is provided with a pre-cooling collar (35).Type: GrantFiled: October 17, 1988Date of Patent: May 15, 1990Assignee: Incom, Inc.Inventors: Richard V. Jeskey, John R. Plocharczyk

Patent number: 4921285Abstract: A connecting rod gearing for windows, doors, etc. having two oppositely shiftable connecting rods under a cover rail. The rotational plane for the toothed rim of a pinion and the plane of motion of the engagement toothings which mesh therewith on two thrust links lie in the cross-sectional area of the housing usually occupied by the cover rail so that the crown (addendum) circle diameter of the pinion can correspond to the complete cross-sectional width of the cover rail. This large pinion diameter results in correspondingly large adjustment differences for the two oppositely shiftable thrust links for a given angle of rotation of the pinion.Type: GrantFiled: May 26, 1988Date of Patent: May 1, 1990Assignee: Siegenia-Frank KGInventor: Horst Loos

Patent number: 4821654Abstract: In order to rationalize the operation of foundries and to avoid environmental stresses, it is endeavored so to rework used molding sand accruing as black sand and to free it from binder residue, so that this sand can be used without restriction like new sand. To achieve this aim through thermo-mechanical regeneration the black sand is heated in predetermined, relative low height layer in a fluidized bed furnace to a temperature exceeding 500.degree. C., preferably 750.degree. C. Through the swirling motions of the heated black sand, preferably supported through strong vibrations of the supporting base, the thermal destruction of the enveloping binder particles and a mechanical liberation of the sand grains form their enveloping binder remains is achieved.

Patent number: 4699511Abstract: An index of refraction sensor utilizing a sensor face inclined at the nominal critical angle of an incident beam, refracts or reflects this incident radiation depending upon the wavelength of that radiation and the index of refraction external to it. The refraction sensor apparatus includes a broadband radiant energy source, a radiant energy guidance and collimating means, a prism sensing element interposed in the radiant energy guide, and a detector for continuously detecting the spectral intensities of the broadband radiant energy reflected by the prism sensing element.
