Patent ES-476404-A1 (ES)
Title: Fluid cooling of glass molds
IPC: C03B11/12
Filed: 1978-12-27
Abstract: The cooling of glass forming molds is accomplished by providing a plurality of radially spaced passages either in the mold itself or in a mold holder in good heat transfer relationship to a mold insert. The passages extend vertically and may either be completely through the mold or may extend substantially to the lower end of the mold. These passages are radially insulated by the compaction of a particulate material such as 316-L Stainless Steel Compacting Powder, with the compressed material being carefully packed within the passage and in surrounding relationship to a coaxially positioned metal tube. The metal tube provides access for the circulation of a liquid coolant. The thickness of the particular material, its degree of compression and its composition and the relative position thereof with respect to cavities of the glass forming mold, will determine the heat flow characteristics of the mold and/or mold holder. Proper selection of the parameters involved results in the desired temperature at the molding surface of the mold.

Title: Process and apparatus for making cubic boron nitride from powdered hexagonal boron nitride.
IPC: C01B21/064
Filed: 1980-06-10
Abstract: Cubic boron nitride has been made from powdered hexagonal boron nitride by a process which comprises vacuum firing of the HBN and conversion by high pressure-high temperature processing at 55-80 kilobars and 1600 DEG C. to the reconversion temperature. The high pressure reaction cell has a special design which prevents the entrance of impurities into the sample. This cell, referring to FIG. 2, comprises, for example, a carbon tube (8) enclosing concentric titanium sleeve (9). Within the cylinder defined by the tube and sleeve are: the HBN sample (4), carbon filler (3), shielding tantalum foil discs (2) and carbon end plugs (10). The vacuum firing is done at pressures of 10-5-10-10 mm Hg, 1400 DEG -1900 DEG C., for 5 minutes-4 hours, and is believed to form a thin, free-boron coating on the HBN particles. The process works on both pyrolytic (turbostratic) and graphitic hexagonal boron nitride. Grinding grits formed by milling cubic boron nitride chunks recovered from the high pressure-high temperature process have resulted in higher grinding ratios than commercially available CBN.

Title: Production of powdered metal articles
IPC: B22F7/06
Filed: 1981-05-06
Abstract: A method of forming an article e.g. a bearing assembly A by bonding together two or more members formed from powdered metal, comprises forming a first member 10 having the desired configuration from an iron base powdered metal containing a sufficient amount of copper to cause the member to expand upon sintering, forming a second member 12 into a configuration such that it is adapted to engage in an interference fit with at least part of the first member, the second member being formed from an iron base powdered metal containing a sufficient amount of nickel to cause the member to shrink upon sintering, fitting the second member to the first member to form an interference fit therewith and such that on sintering the first member expands against the second member which, in turn, shrinks against the first member, and heating the assembly of the first and second member at a sintering temperature which is sufficient to cause the members to become metallurgically bonded together. Preferred compositions for the copper and nickel bearing powders are, respectively, by weight, Fe 93-96% Cu 3-6% C 0.5-1% and Fe 95-97.5% Ni 2-4% C 0.5-1%.
Patent ES-8205304-A1 (ES)
Title: Fluid injectors.
IPC: F23D11/28
Filed: 1981-07-15
Abstract: A fluid injector 1 for an oil fuel burner suitable for firing the fuel of a boiler includes an injection device 2 which can be inserted into the wall of the boiler to an operating position at which oil discharge can be safely permitted and withdrawn from that operating position for inspection and servicing. A flow control valve 3 of the fluid injector 1 is adapted for connection to an oil fuel and delivery circuit and is mounted in a fixed position relative to the boiler wall. The fluid injector 1 also includes a fluid coupling device 11 between the injection device 2 and the flow control valve 3. The fluid coupling device includes male and female terminals 19 and 20, respectively, which are fast with the injection device 2 and the flow control valve 3, respectively. The male and female terminals 19 and 20 are disconnected as the injection device 2 is withdrawn whilst the change-over valve remains mounted to the boiler wall and connected to the oil fuel and return circuit, at which time the female terminal 20 isolates that circuit from the withdrawn injection device 2 and seals flow from the circuit within itself. When the injection device 2 is inserted to its operating position, the male terminal 19 interconnects with the female terminal 20 to communicate the oil fuel and delivery circuit with the injection device 2 through the flow control valve 3. The flow control valve 3 may provide a direct flow path through itself when the injection device 2 is withdrawn to allow oil to circulate continuously in the oil fuel and delivery circuit at that time.
Patent ES-8307507-A1 (ES)
Title: Needle assembly with vein entry indicator.
IPC: A61M5/178
Filed: 1982-02-24
Abstract: A needle assembly (10) preferably suitable for single sample blood collection and for determining vein entry when collecting a blood sample from a patient includes a housing (12) with an interior chamber (40) having a blood inlet needle (14) on one side of the housing (12) and a blood outlet needle (15) on the other. The outlet needle (15) extends into the chamber interior (40), is open at its distal end (45) and includes a side hole (48) therethrough. A vent plug (26) covers the side hole (48) by surrounding the outlet needle (15) inside the chamber (40), while a blood soluble sealant plug (27) covers the open end (45) of the outlet needle (15). This arrangement delays liquid from flowing into the holes (45, 48) while allowing gas to flow through the vent plug (26) into the side hole (48) for escape from the assembly (10) whereby the prevented liquid may then be viewed by a user through a transparent portion (42) of the housing (12). The sealant plug (27) is removable from the open end (45) by dissolving it into the blood inside the chamber (40) so that liquid is allowed to flow into the outlet needle (15) for collection.

Title: Bridge scraper for direct material feeding
IPC: B65G43/08
Filed: 1982-12-14
Abstract: The invention relates to a bridge scraper for raking material from a storage heap onto a belt conveyor by means of a scraper chain mounted on a bridge which also carries a carriage which feeds material from the heap to the scraper chain.
