Title: Electric arc welding
IPC: B23K9/09
Filed: 1965-08-05
Abstract: An arc welding supply system comprises a primary power supply to maintain an arc between the electrode and the workpiece and a secondary supply providing pulses of current to effect spray metal transfer. The pulses are derived from a D.C. source such as a half or full wave rectified supply which is gated by a synchronously driven commutator, having a plurality of tracks having differently spaced conductive areas to provide a selectable pulse frequency. A centrifugal switch rotatable with the commutator disconnects the secondary supply at other than the determined speed. The supplies may be derived from an alternator driven by a prime mover which also drives the commutator.

Title: A Continuous Process of Coating by Vapour Deposition.
IPC: B65G35/06
Filed: 1967-07-27
Abstract: In a continuous process of vapour depositing a coating on sheets such as glass or plastics, the sheets are conveyed through inter-connected vacuum chambers of varying pressure conditions where they are cleaned by a glow discharge prior to being coated from one or more evaporation sources. The coating materials may be metal such as Al or Cr, a metal oxide such as Si O 2 or a metal halide. In an example, sheets of glass are first coated with Cr and then with Si O 2 . The sheets may be heated to 200 -700 F. prior to coating and the evaporation source is preferably heated by electron beam. As shown in Figs. 1 and 2 the sheets are washed in detergent at 11, rinsed and air dried at 12 preferably with air ionized by an A.C. corona discharge. By means of a turntable 14, loader 16 and transfer section 17 pairs of sheets are held vertically in a carriage which grips the top edge of the sheets and conveyed successively through vacuum chambers 26, 28, 31, 34, 40 and 44 at respective pressures of (2 x 10-1 - 5 x 10-3), (1 x 10-1 - 1 x 10-3) for glow discharge (5 x 10-2 - 1 x 10-6) for preheating (1 x 10-4 - 1 Î 10-7) for coating (1 x 10-4 - 1 x 10-7) and (2 x 10-1 - 5 x 10-3) and controlled by valves 25, 27, 29, 32, 36, 45 and 47. The sheets are first dedusted in chamber 23 with ionized air, subjected to a glow discharge in chamber 28 using aluminium electrodes, optionally preheated in chamber 31 and coated in chamber 34 by being conveyed past three vertical rows of vapour sources 41, 42, 43 with four sources in each row. The conveyer in the coating chamber is in three sections, feed section 38 which slows down the sheets at the first coating zone to synchronize speed with that of the constant speed centre conveyer 37, and discharge section 39 which accelerates the sheets for transfer into chamber 40. The coated sheets are finally passed to chamber 44 which is vented to atmospheric pressure, cooled at 48 and conveyed along line 50 to the discharge and recharge point of the loading system.

Patent ES-355973-A1 (ES)
Title: Nuclear Fuel Elements
IPC: G21C3/04
Filed: 1968-07-10
Abstract: A fuel element for use in a reactor in which molten sodium coolant flows upwardly comprises cladding 12 containing fuel, e.g. plutonium and/or uranium oxide (not shown), this fuel element being grouped with other identical elements within a can 16 having wide coolant apertures 18. A fission product vent situated at the upper end of the cladding 12 comprises a ledge 22 penetrated by a tube 20 through which the fission gases pass. On the ledge 22 is easily melted material 24 such as lead or lead alloy whose melting point lies between the temperature of the sodium coolant at reactor shut-down and the temperature of the coolant when the reactor is operating. A tube 30 communicates with the reactor coolant through holes 36 in the cladding. When the fuel element is placed in the shut-down reactor the chambers 32, 28, 42 are filled with an inert gas the same as that provided for the gas cushion situated above the molten coolant. Thus the coolant enters the holes 36 to compress the gas but the arrangement is such that the coolant level 38 does not reach the top of the tube 30. When the pressure of the fission gases reaches a predetermined value during the reactor operation an inverted bell-member 26 is lifted by the gas pressure from the ledge 22 and the gases bubble through the easily melted material 24, depress the level of the coolant within the chamber 32 and escape through the holes 36. The chamber 42 and tube 44 prevent any of the material 24 which may accidentally enter the tube 20 from reaching a space 46 communicating with the fuel. When the reactor shuts down, the material 24 solidifies and forms a seal. Modifications of the ledge 22 and bellmember 26 are described with reference to Figs. 2-4 (not shown).

The carrier is maintained in engagement with the rollers 18 by a spring-biased roller 28. The transfer mechanism is specified for a machine for manufacturing bolts, nuts and similar articles.
Patent ES-360108-A1 (ES)
Title: Improvements in or relating to inorganic oxides
IPC: H01F1/11
Filed: 1968-10-26
Abstract: A dry, granular oxide including compound oxides containing atoms of more than one metal is made by dripping or spraying a stoichiometrically mixed solution of heat-decomposable metal salts on to a mechanically agitated upper surface of a heated bed of grains of such decomposition product, while the bed surface is maintained at a constant level sufficiently high to ensure complete submersion of the mixing elements in the granular material. The bed level is maintained by constantly withdrawing granular product and subjecting it to further heating, combined with mechanical agitation, to convert a desired proportion of mixed oxides to compound oxides. No carrier gas stream is used in the decomposition bed. Ferrites may be made by decomposition and calcination of metal nitrates. In an example, a manganese zinc ferrite having 60% spinel structure is made using a bed temperature of 250 10 C. and a calciner at 800 C. The particles leaving the bed are 50-150 microns in size. Nitric acid is recovered by leading oxides of nitrogen in 10 to absorption columns 11, 12 provided with O 2 inlet 14, water-cooling tube 15 and nitric acid collectors 16. Residual oxides of nitrogen are removed by reaction with an aqueous ZnO suspension in vessel 17 (see Specification 1,221,426). The resulting zinc nitrate is recycled to containers 1, 2 or 3.
Patent ES-362361-A1 (ES)
Title: Process and Device for the Treatment of Single or Multi-Layer Hoses.
IPC: B29C35/02
Filed: 1969-01-10
Abstract: A flexible hose T, which has been made by extruding an elastomer mixture, containing one or two reinforcing inlays of steel mesh, over a rod-shaped core, surrounding this with a textile mesh, and extruding a further elastomer layer over the textile mesh, is submitted to a consolidating and vulcanizing treatment by being passed, either in steps or continuously, through a heated chamber 1 containing a cylindrical membrane 2 which is hermetically sealed at its ends to the ends of the chamber whereby fluid pressure may act via the membrane on the hose. This is effected by supplying fluid from a chamber 12 via a pipe 4 to the space 6. Pressure is preferably produced by a piston 8 acting in a cylinder 8 one end of which provides the chamber 12, piston 8 being driven by a reversible air motor 9, 10. A stop valve 14 is provided in the pipe 4 which facilitates removal of air from the latter. Heating of the chamber 1 is accomplished by applying a low voltage and high current to the ends of the chamber wall so that heating is obtained owing to the resistance of the metal from which the chamber is made. A heating coil is arranged in the chamber 12 to heat the fluid, e.g. mineral oil, therein. One or more thermostats may be used to control the temperature of the chamber wall and of the fluid in chamber 12.

Patent ES-366458-A1 (ES)
Title: Copying machine
IPC: G03G15/28
Filed: 1969-04-25
Abstract: A copying machine has a scanning window 22 and an exposure window 64, the original 12 to the copied being reciprocated past the scanning window by rollers 8, 17 and 7, 18, such that the original moves in the forward direction in synchronism with copy paper moving past the window 64 and in the reverse direction at a speed greater than that in the forward direction. Rollers 9, 16 feed the original 12 into the machine past a photo-cell 13 which causes energization of a clutch (K-6) Fig.3 (not shown), which drives copy paper rollers 35, 36 Fig.1. The rollers 35, 36 feed the copy paper past a cutting device 37, 38 which cut a length of copy paper corresponding to the length of the original. Rollers 35, 36 are stopped when the trailing edge of the original passes the photo-cell 13. Light from exposure lamps within reflector 25 is reflected by the original along the dotted line 27 through lens 28 and window 64 to expose copy sheets eletrostatically charged bycorona devices on opposite sides of the sheets. A shutter 31 is actuated externally to time the exposure. A selector dial 107 is adjusted to the required number of copies before or during machine operation. If multiple copies are required the leading edge of an original is sensed by a photo-cell 15 to cause repeated reversal of the original at a speed greater than the forward speed under the control of a circuit Fig.3 (not shown), which energizes forward and reverse clutches (K-7) and (K-8) respectively and prevents copying during reversal of the original. Latent images formed on the cut sheets are developed by passage through a trough 47 Fig.1 benealth a drum 48. The supply of developer in the trough 47 is replenished by a pump, not shown, from a tank 57 which can be pulled out from the machine by a handle 58. Wipers 51 and 52 engage the drum 48 and a squeeze roller 52 to prevent offsetting of a previous image. The developed image is dried by a lamp 59 around which circulating air is passed by a blower 24.

Patent ES-380946-A1 (ES)
Title: Automatic remote meter reading over telephone line
IPC: H04M11/00
Filed: 1970-06-19
Abstract: Data, such as the identity and total of a public utility meter, is sent to a central processing station over a telephone network and at timed intervals, such as two or four weeks, by means of a telephone substation attachment which at each expiry of a timed interval dials the processing station and in response to an acknowledgement signal sends the data. The period between meter readings is timed by an electrochemical device which deposits silver from an electrolyte and the current through which stops when all the silver has been deposited on one electrode, reversal of the electrodes reversing the process of deposition to time a further interval. Such a timer 25 sets a latching circuit 33 which operates a relay 35 to sense the free/busy condition of the substation telephone line. If the line is busy the circuit waits. If or when the line is free it is looped by operation of a relay 48 and a period of 3 seconds is timed at 46 to presume receipt of dial tone before a motor driven multifrequency number sender 20, 21, 22 is operated to dial the number of the processing station. From the beginning of sending a timer 63 waits for an acknowledgement audio frequency signal from the processing station as detected over filter 72 and triggers 73, 74. Receipt of the acknowledgement in time resets the timer 63 and causes the meter 23 to send its identity and total. If the data sent by the meter is not satisfactory the processing station sends a repeat of the acknowledgement signal to reset timer 63 once more and obtain a repeat of the data. When satisfied the processing station sends an audiofrequency shutdown signal which over filter 81 and trigger 82 resets the latching circuit 33. If timer 63 times out before an acknowledgement signal is received, or when the call is blocked or misdirected, the telephone line is released by dropping relay 48 momentarily before reseizure and a further attempt to set up the connection. Such attempts are repeated until acknowledgement and shut-down signals are received. The attachment withdraws by releasing relay 48 if during its sending function a call is originated over the line by the associated substation. The attachment renews its attempt to send as soon as the substation frees the line. The attachment is locally powered but may be powered over the exchange line.
