Title: Method and apparatus for pouring molten metal
IPC: B22D11/11
Filed: 1978-09-12
Abstract: A metal stream is protected from atmospheric contamination during casting by shrouding it with an inert gas from a gas source at the pour nozzle. The gas is supplied to a low turbulence zone at the nozzle which has a width at least one third of the length of the poured metal stream. The gas source may be an annulas surrounding the nozzle and having its inwardly and downwardly facing surfaces of perforated metal sheet and the outermost surfaces may be disposable in order to tolerate metal splashing.

Patent ES-474394-A1 (ES)
Title: Bonded polycrystalline diamond body-silicon carbide or silicon nitride substrate composite
IPC: B22F7/08
Filed: 1978-10-20
Abstract: The composite comprises diamond crystals and a substrate of polycrystalline silicon carbide or silicon nitride bonded by silicon carbide and a carbide and/or silicide of a metal which forms a silicide with silicon. A mass of diamond crystals in contact with a mass of eutectiferous silicon-rich alloy and a silicon carbide or silicon nitride ceramic substrate are disposed in a container and placed within a pressure transmitting powder medium. Pressure is applied to the powder medium resulting in substantially isostatic pressure being applied to the container and its contents sufficient to dimensionally stabilize the container and its contents. The resulting shaped substantially isostatic system of powder-enveloped container is hot-pressed whereby fluid eutectiferous silicon-rich alloy is produced and infiltrated through the interstices between the diamond crystals and contacts the contacting face of the substrate sufficiently producing, upon cooling, an adherently bonded integral composite. In a modification, the use of a container is avoided by pressing a cavity in the pressure transmitting powder medium, placing the silicon-rich alloy, diamond crystals and silicon carbide or silicon nitride substrate in the cavity, covering the cavity with further powder medium, then applying isostatic pressure and hot pressing.

Patent ES-8206640-A1 (ES)
Title: Method for surface hardening cams.
IPC: H01J37/317
Filed: 1981-09-10
Abstract: Method and apparatus for simultaneously surface heat treating the wear surfaces of a multiplicity of cams (24-27) on a camshaft (4) by transferring to the cam surfaces the energy of a concentrated beam (14) of electrons. The electron beam (14) is directed for a predetermined time to a desired spot on the surface of the said cams (24-27) and is caused to move incrementally from one to the next of a predetermined matrix of spots (28-31) on the work surface as the camshaft (4) is being rotated. After the predetermined matrix pattern (28-31) has been repeated one or more times, the beam (14) is then directed sequentially from one cam (24) to the next (25) and the process repeated until all wear surfaces on the cams have been treated. The predetermined pattern (28-31) is projected over the desired surface of all the cams (24-27) a predetermined number of times so that the material to be heat treated at the intersection of the plane described by the beams's motion and all the cam surfaces being in effect, simultaneously heat treated is brought above the transformation temperature by close control of the electron beam (14) parameters. The beam power and dwell time of the beam at each point are programmed in accordance with the linear velocity of the particular cam surface being instantaneously treated in such a way that the instantaneous energy per increment of surface of each of the cams is made to follow a predetermined law of instantaneous energy input vs. angular position of the cam. Each heat element along the surface of the cam as it moves from under the beam is rapidly cooled by the underlying mass of cold material to effect a quench.

Patent ES-8402060-A1 (ES)
Title: Sealing assembly with a radial slip-ring.
IPC: B63H23/32
Filed: 1982-11-04
Abstract: An annular seal assembly disposed between a shaft surface and a surrounding housing, for example, a seal assembly for an aft-stern tube seal of a sea-going vessel, comprises a nonrotating annular seal element having a circumferentially segmented construction, the segments having overlapping ends. An inflatable annular member, concentrically disposed between the housing and the seal element, sealingly supports the seal element on the shaft surface at the same time providing some freedom for radial vibrating movements to accommodate shaft-eccentricities and radial vibrating movements of the shaft. The seal assembly includes means to admit a controlled pressurized fluid into the inflatable member. The pressurized fluid may be the outboard sea water or any water or air under pressure. The pressurized fluid is so controlled as to maintain a narrow clearance between the shaft surface and the segmented seal element for a lubricant, regardless of seal wear and variation in the pressure head of the fluid. The segmented seal construction offers better performance over conventional nonsegmented types.

Patent ES-8406766-A1 (ES)
Title: Infrared detector for spotting an intruder in an area.
IPC: G08B13/00
Filed: 1983-09-30
Abstract: For reducing the susceptibility to false alarms and for increasing the detection probability of a passive infrared detector, the actual signals obtained from a first sensor element are continuously compared in a correlator with reference or set signals stored in a read-only memory and/or with the actual signals obtained from a second sensor element monitoring the near region. The correlator delivers an output signal which corresponds to the correlation of both signals which are compared with one another. An alarm signal is triggered when the correlation exceeds a predetermined value, for instance 0.7, and the amplitude has reached a predetermined threshold. The infrared detector affords high security against giving of false alarms and a high detection probability, even in the presence of signals possessing a great amount of noise, but also delivers an alarm signal in the event the detector is attempted to be sabotaged, for instance by covering the inlet optical system.
