Title: Bi:metallic steel barrel for continuous casting roller - having external layer of tempered martensite structure stainless steel and inner layer of low carbon manganese molybdenum- niobium steel
IPC: B22D19/16
Filed: 1980-10-01
Abstract: Bimetallic steel barrel for continuous casting roller has an external layer of stainless steel with a tempered martensite structure and an internal layer of a low carbon, manganese-molybdenum-niobium type steel (in which niobium can be replaced by vanadium or tantalum) or a 12 CSDV 7 type steel with a ferrite-rich two phase structure. Barrel is produced by subjecting a bimetallic steel tube to heat treatment at 1050 deg. C for 1 hr, cooling in still air and tempering at 600-650 deg. C for 2-4 hrs. Pref. the original tube is made by centrifugal casting. External layer retards the formation of cracks and the internal layer prevents crack propagation. External layer has a tensile strength of at least 70 daN/sq.mm, a yield strength of at least 50 daN/sq.mm and higher wear resistance than Cr-Mo steels. Internal layer has a tensile strength of greater than 50 daN/sq.mm., a yield strength of at least 40 daN/sq.mm and high ductility.
Patent ES-8204082-A1 (ES)
Title: Gear pump
IPC: F04C2/10
Filed: 1981-01-20
Abstract: A gear pump having an annular internal tooth gear and an external tooth gear eccentrically rotative therein is provided with a choke bore at the inlet side of the pump and a series of outlet pressure bores. The outlet bores are valved with individual check valves so as to pass pressure oil from the pressure pockets between the relatively moving gear teeth which pockets diminish in volume at the outlet side of the pump as the teeth move therepast and the pressure pockets discharge into the outlet bores. Where a pocket is insufficiently filled to effect the pressure needed for opening the first valves moved pass by the pressure pockets, the pressure increases with continued rotation as pocket volume decreases. The increase in pressure in the pockets with volume reduction ultimately opens an outlet bore valve to effect discharge to a common high pressure chamber. Thus, when pump speed is increased, a reduction in inlet suction fails to fully fill the pockets at the inlet zone and the valving arrangement prevents short circuit of flow or back feed from the high pressure common outlet chamber to partially filled pressure pockets at the inlet side causing a recirculation and energy loss. Such partially filled pockets will ultimately discharge as they are reduced in size to force out the oil therein at a valve opening pressure. Provision is made to prevent flow between adjoining pressure pockets.

Title: Escapement mechanism
IPC: B65G9/00
Filed: 1986-05-23
Abstract: An escapement mechanism for advancing a leading one of a row of gravity biased objects supported on a guide comprises a leading stop bracket and a trailing stop bracket pivotally mounted in fixed relation to one another and a piston and cylinder assembly, which pivots the two brackets. The brackets are angularly displaced relative to one another such that at one time, one stop bracket is in the path of the objects to back them up and the other stop is out of the path of said objects. The objects back up against the leading stop bracket and then the piston and cylinder assembly simultaneously pivots the trailing stop bracket into the path of the object immediately behind the leading object and pivots the leading stop bracket out of the path of the leading object to allow the leading object to advance by gravity beyond the escapement mechanism. At a later time, the piston and cylinder assembly simultaneously pivots the leading stop bracket back into the path of the remaining objects and swings the trailing stop bracket out of the path of the remaining objects so that the remaining objects back up against the leading stop bracket.
