Patent ES-8101019-A1 (ES)
Title: Process and apparatus for making red phosphorus.
IPC: C01B25/023
Filed: 1980-02-01
Abstract: The invention relates to a process for making red phosphorus by subjecting molten yellow phosphorus to a thermal conversion reaction in a closed reaction zone. To this end, a hollow shaft-provided and closed ball mill is preheated to a reaction temperature within the range 280 DEG to 590 DEG C. Yellow phosphorus is continuously introduced into the ball mill through the hollow shaft in quantities per unit time which permit the reaction temperature prevailing inside the ball mill to be maintained without supply of heat from the outside. More particularly, decreasing quantities of yellow phosphorus are introduced per unit time at increasing temperature and increasing quantities of yellow phosphorus are introduced per unit time at decreasing temperature within the limits specified. Red phosphorus is allowed to cool inside the ball mill, water is poured over it and the whole is subjected to wet-grinding. An aqueous suspension of red phosphorus is finally removed from the ball mill.

Title: Process for the manufacture of color developing material and product
IPC: B41M5/155
Filed: 1980-05-21
Abstract: Potassium hydroxide or another alkaline potassium compound is used to adjust the pH of an aqueous color developing clay coating composition in the manufacture of color developing material for use in pressure-sensitive or similar copying systems. This reduces the decline in reactivity with time of such material and increases initial print intensity compared with conventional material in which the corresponding sodium compound is used for pH adjustment. Especially good results are obtained where the material being coated is a paper of high acidity such as results from rosin/alum sizing.

Title: A power metal-forming press.
IPC: B30B1/28
Filed: 1981-05-27
Abstract: A power metal-forming press of the underdrive type having a pair of laterally spaced rocker shafts journaled in the base. A set of vertical pull rods are connected to arms at the ends of the shafts for reciprocating the press slide. Driving subassemblies are provided at the near side and far side of the press each including a main drive gear carrying an eccentric. A pitman pivotally engaging the eccentric has a short arm which is coupled via a connecting link to a rocker arm on one of the shafts. The pitman also has a long arm extending generally in the opposite direction, the end of the long arm being guided with respect to the frame along a generally longitudinal path. The long arm is so angled with respect to the connecting link under conditions of bottoming of the slide that upon rotation of the main drive gear the short arm traces a generally elliptical path having a major axis which bears an acute angle to the bottoming orientation of the connecting link. As a result the slide moves relatively slower as it approaches its bottoming position and relatively faster as it leaves its bottoming position.

Title: Direction changing path of a roller bearing for an endless linear motion
IPC: F16C29/06
Filed: 1983-12-30
Abstract: The invention provides a shape of a wall surface of a direction changing path of a roller bearing for an endless linear motion. The outer wall surfaces of the direction changing path are formed convex outward. This convex outward outer wall surface can be formed as a spherical band with its center of curvature lying on the axis of revolution of the direction changing path. Such outer wall shape allows a minimum play of the rollers of the roller bearing for an endless linear motion during the direction changing motion through the direction changing path. As a result, stick-slip motion as well as the resistance of the rollers during the direction changing motion are reduced. Accordingly, the total the resistance of the roller bearing for an endless linear motion is reduced, producing an improved roller bearing for an endless linear motion as a whole.
