Title: Protection of graphite surfaces from attack by aluminum monohalide
IPC: C22B21/00
Filed: 1962-08-03
Abstract: In a subhalide distillation process for the extraction of aluminium from aluminium containing material at least a part of the surface of graphite or other carbon material in the apparatus in which the process is carried out, is protected from attack by the gaseous monohalide by establishing a film of gaseous trihalide, or a gas which is inert in relation to the process, over said surface.

Patent ES-337544-A1 (ES)
Title: Slide fastener with woven support tape
IPC: B31D5/00
Filed: 1967-03-03
Abstract: A sliding clasp fastener comprises two stringer tapes each of which consists of or includes a sleeve 5 which partially surrounds a respective interlocking element 2 with integrally connected headed teeth 3, the sleeve having perforations initially of sufficient size for the passage of the headed teeth, the stringer tape having been shrunk transversely to reduce the circumference of the sleeve to less than that of the element, thus securing the element partially within the sleeve with the heads 4 of the teeth protruding beyond the perforations, there being means 6 within the element to prevent relative movement between the element and the sleeve. As described each stringer is produced by feeding the element into a loom through a guide 16, the sleeve being woven over the guide and warp threads being omitted during the weaving to provide the perforations. The guide has a bend in its length so that the heads of the teeth are spread apart as the element and the stringer tape pass the bend, the weft threads 23 being supported against the back of the guide 11 at the bend by a substantially triangular guide 24. Inside the guide is a wedge-like thickening which starts from the bend and which causes the teeth to protrude through the perforations in the sleeve. The teeth are engaged by a toothed roll 18 to move the elements in the guide and on the opposite side of the guide is a roll 19 which has a knurled surface to grip the sleeve 14. The roll 19 has a guide flange 22 to support the sleeve as it moves round the bend in the guide. Beyond the spreading device is a shrinking device (not shown) for shrinking the sleeve onto the elements. Although as shown the stringer tape includes a portion extending from the sleeve by which it is fixed to a garment this can be omitted if desired. A modification is described in which the element is covered by a strip of plastics material bent to U shape or two strips one on each side before the sleeve is woven over it. It is also stated that the stringer tape can be knitted, braided or plaited instead of being woven.

Title: Stabilization of television deflection circuits
IPC: H04N3/223
Filed: 1967-04-22
Abstract: The deflection circuits 12, 13 of a television receiver are stabilized against supply voltage variations by automatically varying the gains of the respective output tubes 16, 19 in accordance with the variations of the respective retrace pulse amplitudes, the vertical deflection circuit additionally being provided with a stabilized voltage derived from a divider network including a temperature-dependent and a voltage-dependent resistor. In the horizontal deflection circuit 12 a pulse amplitude signal is fed from output transformer 23 through a capacitor 30 to a voltage dependent resistor 29 which acts as a variable efficiency rectifier and, in conjunction with capacitor 30, develops a negative bias voltage across a capacitor 35 which is dependent upon the average amplitude of the retrace pulse. This variable bias is applied to a control grid of the tube 16 through members 31, 32, 33, 22 to automatically vary the gain and so stabilize the image width. The arrangement also stabilizes the rectified high voltage applied to the tube 10 via members 23, 24 by virtue of the aforementioned control of the tube 16.

Patent ES-365395-A1 (ES)
Title: Hollow carbon electrode
IPC: H05B7/085
Filed: 1969-03-28
Abstract: To prevent the escape of arc stabilizing, ionizing gas through the porous walls of a hollow carbon electrode, the bore is made gas impermeable. Various sealing procedures are described. The surface of the bore may be sealed by carbonizing materials in the absence of air, suitable impregnating materials being tar, pitch, synthetic resins or sugar solutions. The bore surface may be impregnated with waterglass and then heat treated so that the pores are filled with silica. Pyrolitic carbon may be deposited on the surface of the bore to render it gas-tight. Metallic coatings may be used to effect sealing, deposition being effected by electrolysis or by the decomposition of organic metallic compounds. Instead of coating the surface, a metal tube or gas impermeable carbon or graphite tube may be pressed into the surface of the bore. The sealing materials may also assist in stabilizing the arc, suitable ionizing additives being potassium fluoroborate potassium sulphate, tungsten carbide, or titanium carbide. Gunite can also be used as sealing process.

Patent ES-373979-A1 (ES)
Title: Shift register comparator having failsafe qualities
IPC: G06F7/02
Filed: 1969-11-27
Abstract: Serial pulse trains A, B in which words are encoded using a "comma-free" code with a predetermined minimum frequency of alternation between 0 and 1 bits are shifted into respective registers 12, 14 and corresponding pairs of bits are compared in stages 22a-22f, each of which comprises an upper and lower transmission path 26a, 25a for the output of an A.C. generator 16, each path including a pair of series-connected power switched A.C. amplifiers such as 27a, 28a controlled by the outputs of the associated register stages FF such that the upper or the lower path in each stage is only completed if the associated pair of bits correspond. The amplifiers 27a &e. Fig. 3 have an A.C. input to a base drive circuit 50, e.g. a transformer which performs a D.C. blocking function, has a fail-safe characteristic and is arranged to overcome the forward conduction threshold of transistor 44 only when the A.C. input level is not below the normal output level of generator 16. The output of the amplifier is taken from an attenuator 52, e.g. a transformer, which reduces the gain to unity so that the same threshold level is applied in each amplifier. Power switching of the amplifier is performed by circuit 36a. A positive 1 bit on input 59 e.g. from the Q output of FF11 turns on transistor 54 so that point 58 becomes positive and capacitor 60 is charged via diode 64 which clamps power output P to earth so that transistor 44 does not conduct. An earth level O bit on input 59 turns on transistor 56 so that point 58 is earthed and the output P goes negative to allow conduction of transistor 44. Capacitor 60 is chosen so that if a 0-1 transition does not occur within the maximum allowable interval, e.g. 5 bits, the charge on it falls to a level below which transistor 44 does not conduct. Fail-safe operation is ensured if generator 16 fails or if one of the register stages freezes in either state or if the minimum allowable 0-1 transition frequency is not maintained.
