Patent ES-383945-A1 (ES)
Title: Manufacture of globular powder
IPC: C06B21/00
Filed: 1970-09-24
Abstract: A method of preparing globular propellant powder wherein presized lacquer particles are entrained in a liquor suspending medium and forced to flow through a long section of tubing until the propellant grains are dewatered and rounded into spherical shape. The spherically shaped powder globules are then passed into a flash evaporator having a pressure lower than that in the dewatering and shaping conduit so that a portion of the solvent within the globules volatilizes. The remaining solvent is removed by passing the slurry through a final hardener consisting of several chambers. Each of these chambers are individually heated to increase the temperature of the slurry of powder granules as it moves through the column. The temperature gradient between adjacent chambers in the latter stages may be increased.

Patent ES-8203717-A1 (ES)
Title: Erasing typewriter with automatic selection of automatic or manual erase mode.
IPC: B41J5/30
Filed: 1981-01-27
Abstract: In response to actuation of the erase key, the typewriter determines whether automatic erasing is possible i.e. whether the selected location of the memory contains an erasable character. If the selected memory location contains an erasable character, an AND gate (100), subjected to inputs identifying an erase key actuation and a character code from the memory decode, provides an output which causes the execution of an erase cycle. If the selected memory location does not contain an erasable character, the typewriter terminates the erase cycle with a backspace, and an AND gate (101) or an AND gate (102) causes the setting of a manual erase latch (112). Actuation of a character key as the next actuated key completes the manual erase, through AND gate (103). Actuation of a key other than a character key resets latch (112) through AND gates (104, 105, 106).
