Title: Method and apparatus for cutting pins for producing chain links
IPC: B23D21/00
Filed: 1971-06-15
Abstract: The production of pins which subsequently are to be bent and welded to form chain links, in which each pin is cut off a rod by a pair of equal wedge-shaped blades which are simultaneously reciprocated in opposite directions to each other within a common central plane extending transverse to the axis of the rod, and which while cutting impress V-shaped notches into diametrically opposite sides of the rod so that the ends of each pin have an angular shape similar to a peaked roof. One preferred embodiment of the invention provides that, instead of forcing the two blades so deeply in the material that their cutting edges engage with each other and thus cut off each pin completely, the blades are impressed only for such a distance into the material that a thin connecting web-remains between the pin and the rod supply which web is then shorn off by moving the pin transversely relative to the rod.

Title: Sealing element for use in internal combustion engines
IPC: C22C27/04
Filed: 1973-10-31
Abstract: Sealing elements for use in internal combustion engines, such as piston rings for reciprocating pistons, seals for rotary pistons in engines of the type generally referred to as the Wankel engine, and similar structures in which a sealing element having a hard, wear-resistant bearing surface provides a seal between relatively movable slidable surfaces to prevent or substantially reduce flow therebetween of fluids such as combustion gases, oil films and the like. Such hard, wear and scuff-resistant facings, coatings and the like are preferably provided by the plasma jet application to the peripheral bearing surfaces of the sealing elements of alloy-forming compositions comprising effective proportions of a tungsten carbide-cobalt aggregate molybdenum and a nickel-chrome-boron-silicon alloy. For best results the plasma-applied final coating is substantially free from such detrimental components as nickel in its free state and aluminum oxide. If the nickel is present only in a combined form, as it is in nicrome (a nickel-chrome alloy containing about 60% Ni), the nickel has no detrimental effect.
Patent ES-427982-A1 (ES)
Title: Method of manufacturing an extruded metal component
IPC: B21C23/10
Filed: 1974-07-05
Abstract: The manufacture of an extruded metal component of the kind including a hollow substantially cylindrical body defining one or more axially extending splines at its external surface involves engaging a first punch with one end of a hollow, substantially cylindrical metal billet. The first punch is then used to perform an extrusion operation on the billet by causing the billet to undergo movement relative to a die cavity. The extrusion operation is arranged to cause material of the billet to flow so as to produce the required one or more axially extending splines and, during the extrusion operation, a load is applied to a second punch to urge the second punch against te other end of the billet. The load applied to the second punch is such that the second punch is moved relative to the die cavity by the material being extruded, but at the same time the material being extruded is shaped by the second punch so as to substantially fill the die cavity and thereby define the end of the component corresponding to the other end of the billet.

Patent ES-439516-A1 (ES)
Title: Apparatus and method for emplacing a conduit along an underground arcuate path
IPC: E21D9/08
Filed: 1975-07-17
Abstract: A method for emplacing a production casing such as a pipeline or other conduit beneath a surface obstacle such as a water course is disclosed. A drill is provided which has a trailing drill string. A pilot hole is drilled along an inverted arcuate path beneath a surface obstacle from one side to the other side of the obstacle so that the drill string occupies the pilot hole. A reamer is provided which has a relatively smaller leading end and a larger trailing end. The leading end of the reamer is attached to one of the ends of the drill string, and an end of the production casing is attached to the trailing end of the reamer. The production casing is thrust into the pilot hole at one side of the surface obstacle to project the reamer with the production casing following into the pilot hole. As the production casing is thrust into the pilot hole at one side of the obstacle, the drill string exits the pilot hole at the opposite side of the obstacle. The reamer is operated by rotating the production casing or other method simultaneously with thrusting the production casing into the pilot hole to scarify and dislodge the earth circumscribing the pilot hole. The pilot hole is enlarged to a diameter slightly greater than the production casing to provide an annulus between the production casing and the reamed hole. Drilling mud is injected through the drill string to exit at the reamer where it entrains the dislodged earth. The drilling mud containing the dislodged earth is allowed to flow into the annulus surrounding the production casing.
