Patent ES-349075-A1 (ES)
Title: Method of faceting gem stones
IPC: B24B9/16
Filed: 1967-12-19
Abstract: A method of faceting a bruted gem stone held in a pot provided with a surrounding guide ring comprises forming a plurality of facets by polishing on a polishing surface and terminating the polishing of each facet when the ring contacts the polishing surface. A bruted stone is inserted into a cavity at the front end of a metal press pot a, Fig. 5, the pot wall around the cavity being axially slit to provide radially sprung fingers b, c, d which grip the stone around its girdle section. The pot is pre-inserted in the front end of a holder e, the front end having a pot holding cavity f surrounded by an inner metal sleeve g, an insulating sleeve h and an outer metal sleeve j. A tight fitting axially slidable metal guide ring k is provided. A first half facet 1a is then polished when portion m of the facet and portion n of the pot have been polished away, lip I of the ring k contacts the polishing wheel and polishing is then terminated. The process is repeated, until facets 1a to 16a on the stone and facets 1b to 16b on the pot have been formed. Polishing then commences e.g. along line B, Fig. 4, to produce a first main facet 17a, polishing being terminated upon contact with the polishing wheel of the peak A2 formed on the pot during polishing of the half facets. The process is repeated until all main facets 17a to 24a have been formed. The machine may have an electric control system including means for automatically lifting the chuck off the wheel when the outer ring (when polishing half facets) or pot (when polishing main facets) contacts the wheel, and means for indexing the chuck about its axis, through 22 degrees for half facets and 45 degrees for main facets, after which the chuck is lowered towards the wheel. Alternatively, the circuit may only indicate when the outer ring or pot contacts the wheel. Alternatively, faceting is effected by visual inspection.
Patent ES-359929-A1 (ES)
Title: Improvements in or relating to flat glass manufacturing apparatus
IPC: C03B18/14
Filed: 1968-11-06
Abstract: An apparatus for dispensing metal pellets, .e.g lead shot, individually into a supply duct 52 connected to a feed head 41. (Fig. 4), which feeds the material of the pellets when molten into a body of molten metal 36 in contact with flat glass, comprises a marshalling hopper 46-47 of width just greater than the diameter of the pellets and having an outlet channel 50 through which the pellets fall in single file, a supply duct 51 (Fig. 3) communicating with the channel 50, a detent 53 in the supply duct which holds back the pellets and an ejector 57 mounted relative to the supply duct where it is connected to the channel and operable by driving means to force one pellet at a time past the detent into the supply duct. The supply duct 51 is extended as a bore beyond the channel 50 and through one side of the hopper, the ejector 53 being mounted in this bore. The ejector is connected to a plate 58 externally of the hopper and to this plate is also connected a disturbance rod 63 extending through a bore 64 into the main body of the pellets. The plate 58 is connected to a spring-loaded piston and cylinder arrangement 60-62 which in the inoperative position with draws the ejector along its bore away from the detent. The cylinder 61 is operated by a signal from a solenoid 66 which is actuated by a control signal related to the lead content of the molten body 36. The supply duct 52 connects with a graphite lined steel feed pipe 40 leading to a graphite feed head 41. The feed head (Fig. 4) has a central bore portion 72, the lower end of which terminates in a downwardly extending portion 73 of lesser diameter from a shoulder 74. A plug 75 seats on shoulder 74 and has a central bore 76 communicating with portion 73, the upper face of the plug 75 being a funnel-shaped inlet 77. The feed head has a protruding nose 82 having an upwardly sloping lower surface into which is fitted a graphite spout 42. The spout communicates with a bore 85 extending upwardly through the nose to the upper surface 86 where it meets an upwardly inclined bore 87 extending from said upper surface 86 to a position near the bottom of portion 73. The bores 85, 87 meet and define a knife edge which in turn defines the level of molten metal to form a reservoir 89. Thus on actuation of the dispenser 45 a lead shot is forced down supply tubes 52, 40 into the feed head 41. It drops in the funnel 77 and if too big to fall down bore 76 into reservoir 89 remains there until it melts and gradually runs into the reservoir. This causes the level to rise and allows molten metal to pass through spout 42 into a recess 43 in the upper surface of an electrode 31 to which a main body 36 of molten material clings and is in contact with the developed ribbon of glass 32. Movement of pellets down supply duct 52 may be assisted by a flow of purging gas through the duct, which gas exhausts through apertures 95, and aperture 81 in the cap 80 of feed head 41 (Fig. 4).

Patent ES-370482-A1 (ES)
Title: Vf pushbutton signaling arrangement
IPC: H04L27/26
Filed: 1969-08-13
Abstract: This relates to "guard" arrangements for a VF receiver, especially for handling 2 x (1 out of 4) code signals from pushbutton subscriber sets. It is shown that if signals from a high-impedance source are applied to an infinite series of resonant circuits whose resonances are in geometrical progression, a guard voltage derived from the input to the infinite series can be opposed to the signal frequencies at the output and gives adequate guard against spurious signals such as speech, without the use of input band-stop filters or of resonant circuits having a precise Q value, as used in known guard circuits.
Patent ES-371575-A1 (ES)
Title: Fuel injection systems
IPC: F02M47/02
Filed: 1969-09-06
Abstract: In a fuel injection system for an I. C. engine, high pressure fuel from an accumulator 15, Fig. 1, supplied by a pump 16, is supplied to a conduit 14 when a valve 17, operable in synchronism with the engine, is opened. The high-pressure fuel moves a stepped metering shuttle 26 towards the small end of associated cylinder 27 against accumulator pressure communicated through conduit 18, the stroke of the shuttle being manually adjustable via an adjustment member 30a. The valve 17 is then closed, whereafter a timing valve 19, movable in synchronism with the engine via mechanical or electrical means, e.g. a solenoid, is moved into a position in which it communicates a low-pressure conduit 21 with the chamber above an injector valve 12. Thus the injector valve is opened by the pressure of the fuel in conduit 14 and allows the fuel to flow to an engine combustion chamber via orifices 11. Consequent return of the shuttle 26 communicates ports 28, 30 and relieves the pressure in conduit 14 via restrictor 29 and conduit 21, thereby causing the injector valve 12 to close. The timing valve eventually moves back to the position shown to communicate accumulator pressure with the chamber above the injector valve. The pressure in the conduit 21 is maintained at a fixed proportion of that in conduit 18 by a spill valve 23 associated with a drain port 24. The valve 12 may instead control the flow of fuel to a conduit leading to an injector (33) Fig. 2 (not shown). In Fig. 3 (not shown), the restrictor 29 is replaced by a valve (34) which is closed when the valve (17) is open, and the chamber above the injector valve is connected to a portion of conduit (18) isolated by a restrictor (35), which conduit portion is periodically communicated to an outlet via a solenoid-actuated valve (40) to create a flow in conduit (18) and thereby a lowering of the pressure in the conduit portion to cause the injector valve to open. In another embodiment, Fig. 4 (not shown), the injector valve (46) is held closed via a push rod by a piston (49) subjected to the pressure in conduit (18), but opens when the closing forces exerted on the injector valve are periodically reduced by a solenoid (51) mounted about the push rod.
