Title: Combustion of titanium tetrachloride with oxygen
IPC: C01G23/07
Filed: 1960-02-10
Abstract: <PICT:0913016/III/1> Pigmentary titanium dioxide is prepared by burning titanium tetrachloride with oxygen as an upwardly directed jet stream through a reaction zone containing incandescent coarse titanium dioxide particles, whereby the titanium dioxide is formed out of contact with fixed surfaces. As shown in the Figure, a vertical cylindrical refractory reaction vessel is provided with an inlet 7 for coarse titanium dioxide particles and an outlet 6 which serves to remove the pigmentary products together with over-flowing coarse tianium dioxide particles. The gaseous reactants are admitted through a tube 4, normally in admixture or the reactants may be admitted through concentric or juxtaposed orifices such that, as they react, they form one jet stream. Thus a mixture of p titanium tetrachloride and oxygen may be fed from a pipe 16 together with a controlled amount of oxygen and/or nitrogen from a vessel 16a. Some of the titanium dioxide replacement particles may be fed into a conduit 19 in admixture with the gaseous feed which may also contain inert gases, carbon dioxide, carbon monoxide, water vapour, hydrogen, hydrocarbons, ethers or esters as nucleating agents or as suppliers of supplementary heat aluminium chloride may be added as a rutile promoter. The titanium dioxide particles are generally between 10 and 65 mesh, coarser particles being removed and submitted to chlorination. According to Examples (1) a reactor was preheated to 800 DEG C. and coarse titanium dioxide was fed in and the reactor thereafter heated by the admission of carbon monoxide through an inlet 5 together with a nitrogen/oxygen mixture from pipe 4. When the temperature reached 1200 DEG C. a mixture of titanium tetrachloride and oxygen in a 1-1,1 mol. ratio and containing 2% of aluminium chloride was fed in through pipe 4 at 300 DEG C. The carbon monoxide-oxygen feed was adjusted to maintain the bed temperature at 1200 DEG C. titanium dioxide solids were fed in from the top at 250 DEG C. No titanium dioxide incrustations occurred. (3) Titanium dioxide was fed as atomized liquid spray through a pipe passing through cap 21 and terminating at a nozzle at 4a at 90 DEG C., whilst oxygen was fed from line 16 at 300 DEG C. Reference has been directed by the Comptroller to Specification 801,315.

Patent ES-296489-A1 (ES)
Title: Xerographic facsimile system
IPC: G03G15/32
Filed: 1964-02-15
Abstract: In a facsimile communication system both the transmitting and receiving stations are provided with oscillator means together with filter and detector means whereby supervisory and control tone signals may be exchanged between the stations for regulating their operations. The invention is described as applied to a system in which at the transmitting station a document to be transmitted is traversed by a conveyer belt past a cathode-ray tube flying- spot scanner which is scanned in the transverse direction only, and the video signals are generated by a photo-multiplier tube responsive to the reflected light. At the receiving station a facsimile of the document is produced by a xerographic recorder comprising a rotating photo-conductive drum which is given an initial surface charge by a corona discharge device and then selectively discharged by light from a transversely scanning cathode-ray tube, the beam intensity of which is modulated in accordance with the video signal from the transmitter. The resulting charge pattern is developed visually by toner material which, as the drum rotates, is subsequently transferred by a charge transfer process on to a paper web and fused thereon by passage of the web over a heated roller. The drum is thereafter cleaned and cleared of all charge by exposure to a corona discharge, contact with a web of cleaning material and finally illumination by a light source. To maintain the cathode-ray tubes at the two stations scanning in synchronism, scanning synchronizing signals in the form of bursts of sinusoidal signal are added to the transmitted video signal between each transverse scan. The signals control the receiver scanning by way of an automatic frequency control system which also furnishes gatecontrol signals to separate the video and synchronizing signals. The receiving station is provided with a number of switches responsive to the condition of components in the receiver. When the drum is in its proper operating position, the paper supply is not broken, the paper supply is ample and the web cleaner is of sufficient length, an input is provided to an AND gate. Other inputs are provided when the filament of the cathode-ray tube is sufficiently heated and the heated fuser roller is at its operating temperature. A further input to the gate is provided for a control signal sent fom the transmitter, so that when the control signal is received and when all the receiver components are in a condition for operation, an output is provided from the gate which causes the transmission of a control signal back to the transmitter to indicate that the receiver is ready for operation. A signal from the receiver may be used to initiate document feeding at the transmitter., Some receiver operations may be initiated upon reception of synchronizing signals. A signal from the transmitter may indicate that the end of a document has been reached and may cause operation of a paper cutter. The control signals may be multiplexed with the video signals or sent over separate channels.

Title: Manufacture of electric ignitors for detonators
IPC: F42B3/195
Filed: 1964-03-21
Abstract: A method of making electric igniters for detonators for blasting cartridges consists of metallically coating the faces (but not the edges) of a strip of dielectric material, winding a metal filament helically around the strip, depositing a second conductive layer over the first layer and those parts of the filament in contact with the first layer, cutting slots between the filament turns to form a " comb " which is then cut to produce individual igniters. A cardboard sheet, 0.5 mm. thick, is zinc coated by spraying, vacuum deposition or chemical reduction &c., a metallic filament 6, 0.03 mm. diameter, is helically wound round the strip and a second layer of zinc is deposited so as to embed the filament on to the first layer. Slots 8 are then cut out along the edges of the strip between the turns of the filament 6. Cuts are then made along the broken lines 11 to produce individual igniters. Alternative methods include using a strip of only half width and cutting slots along one edge only, or for longer igniters cutting along the lines 11 is excluded while cuts are made along and perpendicular to the median axis 10 passing through the centre of each slot 8.

Title: Fuel injection valves for internal combustion engines
IPC: F02M47/02
Filed: 1969-07-16
Abstract: An I.C. engine fuel injection valve comprises a valve needle 103, Fig. 3, guided at 34c in a housing 10a and co-operating with a valve seat 32a in the housing, the end of the valve needle remote from the seat being a greater diameter than the seat a forward fuel chamber 115 connected via ducts 114, 15 to a fuel line in which a constant pressure of 500 to 1000 atmospheres or more is maintained by a fuel pump and a spool valve 100 having a control edge 111 co-operating with a control edge 112 to allow fuel to enter a rear fuel chamber 116 from the duct 15. When a solenoid (not shown) is energized to cause a core 23 to attract the disc-like end 102 of the spool valve 100 and thereby lift the spool valve, the control edges 111, 112 block the flow of fuel from the duct 15 to the rear fuel chamber 116, and at the same time a conical end 106 of the spool valve is lifted from a seat 105 to allow fuel to flow from the rear fuel chamber via ducts 107, 108, 104 to the engine cylinder. The resultant fall in pressure above the upper end of the valve needle 103 allows the fuel pressure in the forward fuel chamber 115 to raise the valve needle from the seat 32a to permit fuel to flow via the ducts 15, 114 and the forward fuel chamber into the engine cylinder. The rapid movement of the valve needle 103 is cushioned by a stop ring 117. In another embodiment, Figs. 1 and 2 (not shown), the spool valve (26) slides within a bore (40) in the valve needle (35), the flow of fuel into the rear fuel chamber (54) being controlled by a control edge (48) on the spool valve co-operating with a control edge (46) formed within the valve needle. The stop ring (52) for cushioning the rapid upward movement of the valve needle (35) may be replaced by a stick of belleville washers (120), Fig. 4 (not shown).
Patent ES-381052-A1 (ES)
Title: Transition code recognition system
IPC: G06K7/12
Filed: 1970-06-23
Abstract: A transition code recognition system which includes a coded record medium (like a color-coded label) which may, if desired, be secured to an article. The record medium utilizes detectable indicia like color bands placed on the record medium in a reading order so that each color band is different from the preceding one. The color transitions from one color band to the next, when reading, are used to identify binary states "1" and "0," and the transitions obviate the need for a separate clocking arrangement. An optical probe scanner is used to read the record medium by "scribing" or gliding the probe scanner across the color bands, and the changing light signals resulting from the reading operation are routed to electronic circuitry for interpretation and processing.

Patent ES-415540-A1 (ES)
Title: Electrically modified float glass manufacturing methods
IPC: C03B18/02
Filed: 1973-06-04
Abstract: A metallic dispersion of predetermined intensity is developed in a glass surface by introducing a concentration of metal ions into the glass surface while the glass is at a temperature at which it can be modified, and contacting that surface with a molten metal body which is reducing with respect to the metal ions, the time of contact being determined to produce the metallic dispersion of predetermined intensity. The metal ions are introduced into the glass surface by establishing an anode electric flux density from a first molten metal body into the glass surface. Then the metal ions are reduced by establishing a cathodic electric flux density from the glass surface into the molten metal which is reducing with respect to the metal ions. It is critical that there be sufficient alkali-metal ions in the glass surface to provide the cathodic electric flux density from the glass surface without sufficient migration of the reducable metal ions from the glass.

Title: Apparatus for measuring in situ the permeability of a civil engineering working stratum
IPC: G01N15/08
Filed: 1973-06-28
Abstract: The permeability of a flat surface is measured, by pressing down on the surface a central chamber surrounded by an annular chamber. The chambers are open at their bottom, and in the annular chamber is disposed a flexible annular bladder. Air is pumped into the bladder to seal about the central chamber, and then liquid under a predetermined pressure is introduced into the central chamber. The pressure of the liquid is no greater than the pressure of the air in the annular chamber and so the liquid does not leak out laterally. The flow rate of liquid into the central chamber thus indicates the permeability of the subjacent material.
