Patent number: 4628615Abstract: The invention relates to a process and to an installation for the heat treatment of cylindrical bodies, in particular pipes, of ceramic material. During the treatment, the pipes are dried, heated and sintered, and subsequently cooled, in successively arranged chambers.During transportation through the drying zone, the heating zone and the cooling zone, as well as in heat treatment during sintering, the objects are turned about their own axis independently of the transportation rate, so that they are not only evenly heated, but a possible deformation is also prevented. This type of transportation and heating with possible heat exchange between the individual zones makes possible a rapid heating-up without detriment to the cylindrical bodies, and thus a short design length of the installation. Above all, the sintering zone, which must consist of high-value, ceramic material due to the high temperatures, can be kept very small.Type: GrantFiled: July 19, 1984Date of Patent: December 16, 1986Inventor: Gerardus M.

Patent number: 4472887Abstract: A large scale, industrial system and method for dehydrating fruits, nuts or other produce. The system includes two long air tunnels which are placed end-to-end. Each air tunnel has a conveyor which is used to transport the produce through the air tunnel. As the produce exits one air tunnel, it is dropped from one conveyor onto the other, thus permitting the produce to be turned over before it enters the second air tunnel. Each air tunnel is divided into a number of separate air chambers in which the heated, circulating air is confined so as to reduce heat loss, thus increasing the energy efficiency of the system, and also providing for separate control of the air temperature and humidity levels in each air chamber. Countercirculation of air between adjacent air chambers aids in confining the air through the separate air chambers, as well as the use of resilient flaps which are used to enclose the ends of each air chamber through which the conveyor enters and exits.Type: GrantFiled: December 14, 1982Date of Patent: September 25, 1984Assignee: Tagus RanchInventors: Aaron M. Avedian, Lonald H. Jensen

Patent number: 4467530Abstract: A method and apparatus for batch continuous laundry processing involves a system for continuously centrifugally extracting fluids from sequentially received batches of washed laundry. The discrete batches of laundry are continuously received by a conveying apparatus that automatically loads the batches into the discrete compartments defined within the segmented drum of the extractor. While the extractor is rotating, the conveying apparatus arranges a plurality of laundry batches to be quickly loaded into the extractor upon completion of the processing of the previous batches so that the conveying and processing is completely continuous and automatic. The conveying apparatus is vertically, laterally and longitudinally translatable to receive the batches from a washer at one level, to arrange the batches in two rows, and then to automatically feed them, for example two at a time, into the compartments of the segmented extractor.Type: GrantFiled: June 4, 1982Date of Patent: August 28, 1984Assignee: Ellis CorporationInventors: Robert H. Fesmire, Warren T. Hansen
