Title: Improvements in or relating to pyrophoric lighters
IPC: F23Q2/08
Filed: 1950-07-05
Abstract: 692,720. Pyrophoric lighters. MILLER, H. June 21, 1951 [July 5, 1950], No. 16796/50. Class 75(iii) In a pyrophoric lighter comprising a hollow sheet metal casing having a portion to receive an igniter unit and a portion to resiliently grip and releasably retain a fuel container unit therein ignition being effected by the opening movement of a pivoted cap piece through a ratchet drive of the friction wheel, the flint spring at its far end abuts against the casing unit and the igniter unit is slidable from an operative position to a position in which it projects from the casing spring-loaded means being provided to lock the unit in each position; the arrangement is thus such that the flint is not pressed by the spring against the friction wheel when the unit is in the projected position so that the flint can be replaced. A pressed sheet metal casing 1 formed with an open ended cylindrical portion 4 and a box-like portion 5 open at the top and closed at the bottom, resiliently grips a fuel container unit 2 in the portion 4 and carries an igniter unit 3 in the portion 5. The fuel container unit 2 has a lower casing 6 formed with an annular ridge 14 to hold the container within, and a number of ridges 14a to facilitate removal from, the portion 4. A wick 9 passes through a hole in a cap 12 fitted into the top of the casing 6 and into the container through a hole 8 in a U-shaped member 7 fitted into the casing 6. Cotton wool or the like is packed between the legs 11 of the member 7. The igniter unit 3 has a rectangular element 15 which fits into the portion 5. The cap piece 20 has lugs 23 formed thereon to abut tongues 24 formed on the igniter body when the cap is down and a tongue 21 to abut the upper end 22a of a flint tube 22 when the cap is down and a tongue 21 to to the up position and actuates the friction wheel 18 by a spring 30 bearing against the bottom 'of the casing 15 and acting on the lower end 28a of a connecting rod 28 attached to lugs 27 formed on the cap 20; the cap 20 is released by depressing the rear end thereof. The igniter unit.3 is either held in the operative or in the projected position in the portion 5 by a spring-loaded button. 35 entering one of the holes 37 formed in the wall of the portion 5. When the unit 3 is in the lowermost position the flint 32 is pressed against the wheel 18 by a spring 34 bearing against the wall 5b of portion 5. Upon depression of button 35 the unit 3 is moved upwards by a spring 33, compressed between the lower end 28a of the connection rod 28 and the wall 5b of the portion 5, and the spring 34 reaches the limit of its extension before the unit 3 reaches its uppermost position and therefore moves away from the flint 32 thus enabling a new flint to be inserted in the tube 22 through an aperture 31. A saddle 41 slidably mounted on the portion 4 enables slots 40 in the wind shield to be opened or closed.

Abstract: 1390075 Colour television PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 12 April 1972 [14 April 1971 20 July 1971 23 Aug 1971] 16838/72 Heading H4F A television receiver for a PAL or SECAM (Registered Trade Mark) signal includes a switch operated by a generator at half-line frequency in response to received line sync pulses, the generator not being phase-controlled to agree with the received signal, correct demodulation being achieved by the use of a second switch which is operated once to establish correct demodulation, or by the use of two oscillators, one for R-Y demodulation and the other for B-Y demodulation. In the PAL embodiment shown in Fig. 1, the output of half-line frequency switch 17 is fed to a phase comparator 14 which receives an input from burst gate 8 and controls oscillator 16 via a long time constant circuit 15. Oscillator 16 is controlled so that if switch 17 is in position 1-3 for a received signal with +(R-Y) modulation axis, oscillator 16 has an output of - (B-Y) phase and switch 23 is switched by a second phase comparator 25 to position 1-3 to provide a signal of + (B-Y) phase at 24. If switch 17 is in position 2-3 for a received signal with + (R-Y) modulation axis, oscillator 16 has an output of + (B-Y) pulse and switch 23 is switched by 25 to position 2-3. In alternative embodiments oscillator 16 may be operated at + (R-Y) phase and switches 17 and/or 23 may be in the chrominance signal path(s) to the demodulators 6, 7, (Figs. 7, 8, 10, 12, 14, not shown) or switches 17 and 23 may be connected in series (Figs. 4, 8, 9, not shown). Instead of using switches 17 and 23 two half-line frequency ganged switches 451, 480, Fig. 13, may be used, with a B-Y oscillator 425 and an R-Y oscillator 455. In a SECAM embodiment (Fig. 11, not shown) a line frequency switching pulse generator has two antiphase outputs, with an additional switch to select either of these outputs.

Title: Improved manufacture of methane
IPC: C07C1/04
Filed: 1920-06-22
Abstract: In the process described in the parent Specification, methane is prepared by passing a mixture of carbon monoxide and an excess of hydrogen through a series of contact furnaces, and, after each passage, eliminating the water vapour and adjusting the proportion of carbon monoxide in the gases so as not to exceed one-fifth of the hydrogen present.  According to the present invention, in the latter stages of this process, that is, after a high concentration of methane has been attained, carbon dioxide in an amount corresponding to about one-fourth of the hydrogen remaining is added instead of further additions of carbon monoxide; the water vapour is removed after each passage as before.  In an example, the first set of furnaces taking carbon monoxide and hydrogen is heated to 290 DEG C., and the furnaces through which the gases are passed subsequent to the addition of carbon dioxide are heated to 390 DEG  C.  Excess of carbon dioxide may be removed from the gases by absorption by lime &c., and the residue of hydrogen by heated cupric oxide.

Abstract: 650,096. Pliers. AIRCRAFT-MARINE PRODUCTS. Inc. June 27, 1947, Nos. 16991 and 16992. Convention dates, June 27, 1946 and Dec. 23, 1946. [Class 61(ii)] [Also in Groups XXII and XXXVII] A terminal connector blanked and bent up from sheet metal and comprising a connector portion 24, Fig. 2, joined to a ferrule portion 26 having tapered lateral ears 28, 30. 34 is crimped on to a cable by dies 46, 48. Fig. 7, after preforming the ferrule to a U-shape, said dies forming the jaws of a pliers hand tool or being mounted in a standard press. Die 46 comprises three plates 50, 52, 54 channelled at 56, 58, 82 respectively, Fig. 9, the channels terminating in rounded faces 60, 62, 80 which receive the ears 28, 34, 30 respectively when a connector with a cable inserted in the ferrule portion is placed in the rounded face 84 of die 48 and the dies are closed. The cable may be insulated or stripped. Fig. 14 shows the dies completelyclosed on a connector placed on an insulated stranded conductor, the die faces 60, 62 having curled the ears 28, 34 round and forced them through the cable insulation 42 into contact with the core 44, and the die face 80 having curled the ear 30 round the cable insulation thereby serving as a support. Die plate 54 may be shaped similarly to the plates 50, 52 so that the ear 30 also penetrates the insulation 42. Where the cable core is solid, the ears are wrapped thereabout. Fig. 21 shows a modification wherein the ferrule portion 103 comprises opposed ears 103b, 103c bent or rolled to form a cylinder. In this case the connector is crimped on to a stripped stranded conductor by dies 108, 110, the former having a rounded face 109 in which the base of the ferrule rests and the latter having a recess with flat side walls 111 terminating in rounded faces 112 which meet in an edge 113. When the dies are closed, the edge 113 forces the meeting edges of the ears down on to the strands of the conductor as shown in Fig. 19. The ears may have slanting edges so that when rolled up they meet in a diagonal joint, the die edge 113 also being skewed. Thus when the connector is crimped on to the wire, the edges of the ears are parallel to the strands, Fig. 27. Other alternative forms of connector are also described for use with the above dies (see Group XXXVI). Specification 613,013, [Group XXXVI], is referred to.
