Title: Burdens preparation
IPC: C22B1/14
Filed: 1969-02-11
Abstract: A process for the preparation of furnace burden from iron bearing ore comprises introducing the ore, with a portion of sodium carbonate, into a kiln 13 to preheat the ore mixture, feeding the preheated ore mixture to a furnace 17 to melt the ore, and quenching a stream of molten ore to form granules, wherein waste gases from the furnace are introduced to the kiln to effect the preheating of the kiln. Sodium carbonate is preferably added in a portion of 5% wt. of the ore mixture. The ore is preheated to 800 to 1000 C. and melted at at least 1300 C. preferably 1400 C. in the furnace. After being discharged from the furnace, the ore strikes a plumbago wedge 37 where the stream is scattered into an inclined duct 32.

Title: Switch having pivoted u-shaped resilient conductive blade
IPC: H01H23/12
Filed: 1975-02-07
Abstract: The switch has a pair of blades each of which is a piece of flat stock formed into a generally U shape with the shorter leg pivoted on the notched center terminal and normally contacting the N.C. terminal while the longer leg overlies the N.O. terminal. When the actuator (as distinct from the handle) is moved towards the N.O. terminal, the free end engages the terminal with considerable contact pressure while the actuator engages the upstanding tab forcing the blade to the left to wipe the blade on the terminal. The centering spring returns the actuator to normal. When the actuator is moved towards the N.C. terminal, the sloping tab is engaged and the blade wipes the N.C. terminal. In the foregoing the distinction between the actuator and the handle should be kept in mind - the handle moves opposite to the actuator. This switch can handle large DC current without using precious metals, thus achieving greatly improved performance at low cost.

Patent ES-477018-A1 (ES)
Title: Document sorter utilizing cascaded sorting steps
IPC: G06Q30/02
Filed: 1979-01-19
Abstract: An automatic document sorter particularly suitable for sorting retail store coupons employs a plurality of relatively coarse sorting processes in cascade. The sorting processes sequentially sort the documents according to predetermined properties of the document, including codes, such as bar codes or the like physical properties, such as size, thickness, color, reflectivity and opacity the characteristics of the inscriptions on the face of the document and any uniquely marked areas of the document face. Such a sorting hierarchy permits the documents to be sorted rapidly by reducing the precision required in each sorting step. The hierarchy also permits each document to be classified during each sorting step as falling into a particular class of documents in order to simplify subsequent sorting steps. If a property uniquely identifying the document is found during any one of the sorting steps, the processing is terminated at that point without completing the subsequent sorting steps.
