Title: Process and apparatus for seasoning wood
IPC: F26B3/34
Filed: 1976-06-05
Abstract: A process and apparatus for accelerated drying of green lumber employs high voltage dielectric heating at subatmospheric pressure to effect a rapid removal of moisture from the wood without splitting, checking, case hardening, honeycombing or similar damage to the wood structure. The invention combines the advantages of both dielectric and vacuum drying techniques without inefficient and destructive corona, arcing, or ionization effects which have heretofore prevented combining such techniques. When desired, the use of subatmospheric pressures in the drying process also permits injection of suitable chemicals for fireproofing or other specialized treatments of the wood allowing the combination of such treatments with the drying of the wood in a single process.

Patent ES-469159-A1 (ES)
Title: Photocomposing machine and method
IPC: B41B27/28
Filed: 1978-04-26
Abstract: The machine preferably has a character matrix comprising a rotating drum with character-bearing film strips wrapped around it. The machine has a light source comprising a plurality of flash lamps and fiber-optic light pipes. The light-pipes are arranged in a linear array aligned parallel to the direction of travel of the film strips on the drum. Photographic film is formed into a semi-cylindrical arc and remains stationary during composition of up to a full newspaper page of text before the film is moved to another exposure position. Both character spacing and line spacing are performed by a combination of selective timing of the operation of the flash lamps, a lens and reflector traveling parallel to the film in a beam of collimated light, and a swinging mirror mounted on the axis of the semi-cylinder formed by the film. Both timing slits and base-line reference marks are located on the film strips near each character. The base-line reference marks are detected and used to make automatic corrections of the character image locations to ensure excellent base-alignment of the characters on the film. Other corrections of the character image locations are stored in a memory and are made automatically during composition. Several steps are taken to ensure accurate character spacing. A separate, independent timing circuit is used to time the flashing of each character. Also, the timing is determined by reference only to the timing slit immediately next to the character to be flashed. Furthermore, timing delay is controlled by a clock pulse source whose frequency is controlled by the drum rotation so as to compensate for instantaneous variations in drum speed and/or position. Each film strip bears coded indicia indicating the illumination level required for each different type face on the strip. Automatic adjustments are made to compensate for the divergence of the collimated light towards the end of very long lines of type composition. Special means are provided to compensate for the extension of italics and slanted characters to one side or the other of the normal character area. Means also are provided for the insertion of "pi" characters and forming rules.

Title: Method and apparatus for treating an exhaust gas
IPC: B01D53/86
Filed: 1978-08-30
Abstract: A method for treating an exhaust gas containing nitrogen oxides, oxygen and soot, in which the nitrogen oxides are selectively reduced into nitrogen by adding ammonia to the exhaust gas as a reducing agent under existence of a catalyzer, is improved in that the nitrogen oxide is removed by introducing the exhaust gas into a denitration reactor in which a plurality of planar catalyzer packs or catalyzer packs having gas passage holes are arrayed in parallel to a gas flow and a linear velocity of the gas through the reactor is selected at 4-15 m/s. In one preferred mode of the method, soot having a relatively large particle diameter is preliminarily removed by a dust remover disposed upstream of the reactor, while most of the remaining soot is removed by a high performance dust collector disposed downstream of the reactor. Denitration reactor structures suitable for the improved method for treatment are also disclosed herein.

Abstract: An endless chain for an apparatus which carries a plurality of articles to be treated around one or more article-treating drums, the chain and articles being continuously in motion. The chain is formed of a plurality of serially connected links which are joined to each other by pivotal connections, the axes of the pivotal connections being parallel to each other and parallel to the axes of the drums around which the chain travels. Each link has at least one cavity therein which receives the product to be treated, the cavity being of such shape that the product can be introduced thereinto and removed therefrom in a direction perpendicular to the plane containing the axes of the pivotal connecting means for the respective link. The chain travels upon a fixed guide upon which it slides, such fixed guide guiding the links laterally, the chain travelling between parallel fixed guides which prevent the escape of the articles from the cavities except at points where at least one of such latter guides is interrupted. The chain carries driving means which mesh with one or more sprockets mounted to turn about axes fixed with respect to the chain. The sprockets may be affixed to the article-treating drums coaxially thereof.

Title: Procedure for the pre-treatment of aluminium materials, for the extraction of aluminium.
IPC: C22B/
Filed: 1979-01-31
Abstract: The procedure which is the object of this invention destroys the crystalline structure of clay materials principally kaolonite, illite, chlorite, montmorillonite, the instratified and other clay minerals through the application of mechanical energy to the minerals, which may be carried out using any efficient mill, such as a ring mill, ball, rod or Chilean mill and generally any mill which develops a high grade of work, with a significant shear force component. It is possible, by means of this invention, to make the aluminium of the clay minerals soluble with or without prior calcination in acidic conditions much lower than those of known processes with lower excesses and in shorter times.  This is achieved with millings ranging from some minutes to several hours depending on the effectiveness of the mill, which is demonstrated by the destruction of the crystalline structures revealed by the X-Ray charts.

Title: Pilot controlled repeater for analogue transmission system - automatically compensates for changes in analogue signal level
IPC: H04B3/12
Filed: 1979-04-11
Abstract: A repeater (1) amplifiers a range of analogue signals and a pilot signal. A filter (2) passes the pilot signal through an amplifier (3), and a rectifier (4), to one input of a differential amplifier (5). Feedback from the output of the differential amplifier is through a resistor (6) back to its second input. The feedback voltage (V1) is also a function of a fixed reference voltage (Vref). The circuit can automatically compensate for changes in the repeater input signal due to temperature changes in the cable. An alternative version has feedback from the comparator output to the pilot signal amplifier.
