Title: Decarburization of metal
IPC: C21C7/10
Filed: 1970-12-29
Abstract: 1335397 Decarburizing metals; alloys ALLEGHENY LUDLUM INDUSTRIES INC 29 Dec 1970 [5 Jan 1970] 61573/70 Heading C7D Molten metal is decarburized in a closed vessel in a process comprising introducing gaseous oxidizing material into the vessel and establishing a predetermined ambient pressure within the vessel so that oxidation of some metallic values is minimized. The composition and flow rate of the input gases and the composition of the off gases are measured. The expected flow rate of off gases is determined on the assumption that only carbon is oxidized. The expected pressure within the vessel is determined from the relationship between the extractive capacity of the pumping system and the vessel pressure. The actual pressure within the vessel is measured and the composition and flow of input gases are adjusted to maintain the actual vessel pressure at least as great as the expected pressure. The gaseous input may be oxygen together with nitrogen or argon. The process may be applied to the decarburization of alloy steels e.g. those containing chromium.
Patent GB-665755-A (GB)
IPC: H04J3/16
Abstract: 665,755. Electron beam apparatus. GLOESS, P. F. M., and LIBOIS, L. J. March 21, 1949 [March 27, 1948], No. 7678/49. Class 39 (i). [Also in Group XL (c)] The signals in a multiplex pulse communication system (see Group XL (c)) are, in some embodiments, produced by a cathode-ray tube. The beam of a cathode-ray tube 54, Fig. 12, is traversed vertically by a saw-tooth wave applied to deflector plates 56, 57, and produced across condenser 59 by the charging valve 60 and discharge valve 61. The signal transformers 78 ... 81 are connected to individual horizontal deflection plates 71 ... 74. respectively. The beam. which is of elongated cross-section, is thus caused to overlap a target electrode 75 by an extent dependent upon the signal during its passage past the deflecting plates 71 ... 74, and the current in rsistance 76 is thus similarly varied. The charging rate of condenser 59 is controlled by applying the potential across resistance 76 to the grid of the charging valve 60. This causes the sweeping rate of the beam to vary and hence the times at which it crosses the extensions 63 ... 66 of the output electrode 67. The modulated output pulses are due to the beam striking these extensions. The portion of the beam which is not intercepted by the electrode 75 falls on the earthed electrode 77 and the beam is suppressed during the return stroke of the saw-tooth wave. In another embodiment, Fig. 14, the channel signals control the amount of secondary emission from the dynodes 86 ... 89 when they intercept the beam of the cathode-ray tube. The common collector 91 for the secondary emission produces a variable potential on the grid of the charging valve 60, so that the beam passes through the gaps between the dynodes 86 ... 89 at times varying with the signals. The resulting pulses from the collecting electrode 92 behind the dynodes form the modulated output pulses.

Patent GB-2072962-A (GB)
Title: Triac triggering circuit
IPC: H03K17/13
Filed: 1980-03-24
Abstract: A triac triggering circuit comprising a triac (T1) and triggering- pulse generating means connected to the triggering input (TI1) of the triac (T1) to generate triggering pulses synchronised with the alternating voltage applied across the triac (T1) when the circuit is in use. With logic output (LO1) at a positive voltage (1) diode (D1) prevents this being applied to switching transistor (TR1). At the beginning of a positive half cycle current passing via R1a switches on (TR1) to trigger the triac (T1). When it is triggered current ceases through (R1a) and (TR1) is switched off. When the negative half cycle occurs (TR2) is switched on and this causes (TR1) to be switched on momentarily again until, on triggering of the triac (T1), both (TR1) and (TR2) are switched off. When logic output (LO1) is switched to zero voltage (0) the triac (T1) cannot be switched since the base of (TR1) is held close to zero volts. Instead of using transistors other active elements such as operational amplifiers or logic gates could be used. <IMAGE>

Title: A roller blind
IPC: E06B9/60
Filed: 1979-01-22
Abstract: There is disclosed a roller blind with a spring loaded end fitting in which opposite ends of a coil spring 30 are carried by a part 13, fixed in one end of a hollow blind roller 10, and a part 34 which is mounted for axial sliding movement on a tube 18 fixed in a part 11 fixed with respect to a mounting bracket 22. The part 34 has internal longitudinal grooves 36 in which, in the normal longitudinal position of part 34, are received ribs 18a on the tube 18, the ribs 18a being confined to a short section of the tube. As the blind is tensioned and the spring 30 thus wound up, the number of turns in the coil spring 20 increases so that it extends longitudinally, and, before over-tensioning has proceeded sufficiently to damage the spring, the part 34 is pushed longitudinally beyond the ribs 18a allowing the part 34 to rotate on the tube 18 and thus relieve the tension in the spring. The part 34 thus forms, with the ribs 18a, a positive engagement clutch which is disengaged, when the spring is overwound but before the spring has become sufficiently overwound to suffer permanent damage. <IMAGE>

Title: Tobacco smoke filter and its production
IPC: D04H3/07
Filed: 1980-11-21
Abstract: A method and apparatus are disclosed for producing self-sustaining, dimensionally stable axially elongated fibrous bodies of suitable cross-sectional size and shape for use as cigarette filters from a heat-bondable continuous filamentary tow of substantially continuous thermoplastic fibers, wherein transport and shaping of the tow during its processing into a bonded fibrous rod are effected pneumatically. The pneumatic system is designed so as to require the utilization of gas under pressure in sufficiently low amounts to enable eliminating of at least a major portion, and preferably substantially all, of the transport gas in a manner so as not to interfere with the bonding operation. The system further enables variation of the orientation of the continuous fibers within the fibrous rod so that the pressure drop exhibited by the filter elements finally produced may be selectively controlled. The resulting filter elements, in comparison with the prior art continuous fiber filter elements of comparable pressure drop characteristics, require substantially less material and exhibit higher filtration efficiency. In a preferred embodiment the filters (Fig 2) have a resistance to flow higher in the longitudinal direction than the transverse direction enabling a relatively high ratio of ventilation air to smoke when used in an air-diluted filtered cigarette. <IMAGE>
