Patent ES-417234-A1 (ES)
Title: Method of manufacturing sheet and float glass at high production rates
IPC: C03C3/04
Filed: 1973-07-24
Abstract: A method of increasing the rate of production (throughput) of }flat glass, particularly sheet glass manufactured by the Pittsburgh }Process, and float glass manufactured by the Float Process is disclosed. }The method involves altering the standard commercial sheet glass formulations }of the Pittsburgh Process and of the Float Process to give a lower }SiO2 and CaO containing glass which has a higher Na2O content. The new }glass composition melts and fines at lower temperatures and is a surprisingly }more soluble composition for the batch sand which makes the glass composition }faster melting. The new glass requires less salt cake for melting and }fining than conventional sheet and float glass and also retains a higher }percentage of SO3 during melting and refining in the glass than either }conventional sheet and float glass. These factors significantly reduce }the pollution hazards associated with gaseous and particulate sulfur }emissions. Further, since the glass is faster melting, it helps reduce }particulate emissions due to dusting. Further, the new glass has a lower }liquidus temperature, a wider working range, can be attenuated over a wider }temperature range, and is easier to cut. Flat glass articles of the }new composition can be both thermally and chemically tempered at faster }rates. These improved properties all contribute to high throughput }conditions. Although the new glass can be made at higher production }rates, commercially desirable properties, such as chemical durability, }are as good as commercially available sheet and float glass.

Title: Tunnel kiln for drying or firing tiles - has through platform supported by insulating structure forming vibratory conveyor (NL 15.7.80)
IPC: F27B9/24
Filed: 1979-01-11
Abstract: Elongated platform on which goods to be processed are moved forward, extends through a kiln for prodn. of glazed tiles. The platform is supported by a structure extending through an opening in the bottom of the kiln, which is narrower than the platform. Supporting structure, in its turn is held by links attached at their bottom end to a bearing plate on which a vibrator plate is fixed. Elastically deformable props or struts capable of limited motion support the bearing plate and are fixed to an anchorage plate. Used to replace the bogies of tunnel kilns for the prodn. of tiles of all kinds, by a vibrating surface, which results in a threefold advantage. Firstly, considerable economies of energy are made, secondly the ceramic goods of whatever shape can be fired on a perfectly flat surface at a forward speed which can be regulated according to programme and thirdly, equipment and maintenance costs are reduced. A kiln of the same breadth and length as normal, i.e. 2m. x 60m. offers great economies in bogies, moulds, handwork, storage room, etc. since pieces of any size can be laid on the platform without other support.

Patent ES-8101787-A1 (ES)
Title: Regulation circuit
IPC: H02M7/162
Filed: 1979-06-18
Abstract: A regulation circuit for providing timing gate signals to the dc power section of a power supply, the regulation circuit utilizing phase angle conduction of a programmable unijunction transistor. The conduction angle is determined by the occurrence of the cycles of the ac source voltage unless earlier conduction is determined by the sensed dc voltage. Early conduction occurs when the control voltage to the PUT is allowed to build up beyond a predetermined level when the sensed dc voltage is low. When the sensed dc voltage is high, an electronic switch closes to discharge a storage element to prevent control voltage build up and, hence, early conduction. When there is an ac source voltage outage, a diode connected to the control voltage output conducts to keep the control voltage to zero and hence closing of the electronic switch to prevent undue regulation of the power section output at such times and to permit storage capacitors therein to maintain a dc output until source voltage is reestablished. Soft start elements in the form of long time constant components ensure against the application of peaked voltages during initial start up and in the presence of power surges.
