This temperature is measured by a helically wound bi-metallic strip 44 contained in the hollow shaft 18 of the butterfly. The bi-metallic strip is connected at one end to the hollow shaft and carries the lever 47 at its other end. Fluid is fed to the bi-metallic strip through grooves (50) Fig. 5 (not shown) in the butterfly and ports (49) Fig. 3 (not shown) in the hollow shaft. In operation, pressurized fluid is fed from an inlet 31, Fig.2, through passages 32, 33 to a diaphragm arrangement 24 which moves the butterfly to the closed position. Simultaneously the lever 47 is positioned adjacent a prong 48 of a flapper 36 of the bleed valve so that an increase in temperature at the butterfly opens the bleed valve and reduces the actuator. A spring 30 opens the butterfly in accordance with the reduced pressure.

Patent GB-1138779-A (GB)
Title: Improvements in or relating to imaged masters
IPC: B41M5/025
Filed: 1967-08-23
Abstract: 1,138,779. Printing with colourless inks; developing; transfers. A. B. DICK CO. 23 Aug., 1967 [24 Aug., 1966], No. 38913/67. Heading B6C. [Also in Division G5] A spirit master system comprises first portions imaged with a visible spirit-soluble dyestuff and second portions imaged with a dyestuff soluble in the same spirit but substantially colourless until a further reactant is applied thereto. Particular examples relate to the production of multiple copy sheets from a single master wherein an instruction, question or statement is formed in the visible dye-stuff, and the colourless dyestuff is formed in an answer area so that a student may mark the area with the further reactant, the colour of the resulting mark indicating whether the answer was right or wrong (Figs. 4 and 5, not shown). Preferably the colourless component is applied in a coating composition to a support while the visible component is applied in a coating to a separate base; the coatings are then transferred image-wise by heat, pressure or radiation to a single or respective master sheets and the -master or masters are then spirit duplicated on to copy sheets on a rotary duplicator. The "spirit" is generally water or ethanol; the colourless dyestuff may be gallic or pyrogallic acid made visible with ferric chloride, or nickel acetate, copper acetate or copper chloride made visible with dithio-oxamide; the visible dyestuff may be crystal violet; the base of the transfer sheets may be paper, aluminium film or polyvinylidene chloride foil. The reactant which develops the colourless dyestuff is generally in a marking solution containing 0À5 to 5% by weight of the reactant, and 0À005 to 0À1% by weight of a further tinctorial agent which gives a mark made by the solution a distinctive coloration even when not contacted with the complementary dyestuff.

Abstract: 1,001,788. Gas-fuelled lighters. JACQUES KREISLER MANUFACTURING CORPORATION. Oct. 3, 1963 [Oct. 11, 1962], No. 38952/63. Heading F4F. A liquefied gas lighter comprises two regulating valves in series for regulating the flame. A valve housing 52 is welded into an opening in the top of a liquefied gas reservoir and gas is admitted to the housing through a port 60 therein. A dispersion plate 64 has a shank 66 extending into the port 60 and filtering material 68 is placed between the plate 64 and the bottom of the valve housing. The first gas regulator comprises a member 70 slidable in the valve housing and having a reduced portion 72 bearing against further filtering material 74 over the dispersion plate 64. Pressure is applied to the regulator 70 by a headed sleeve 80 threaded into the valve housing. An 0-ring 76 surrounds the reduced portion 72 of the regulator. The second regulator comprises a member 90 having a gas opening 96 which tends to close when the member 90 is squeezed by a pressure plate 98 actuated by an actuator 110 threaded into the headed sleeve 80 and carrying a member 112 having a hexagonal shaped periphery and extending through a rotatable element 116 supported in an opening in the top of the lighter.

Title: Electronic switching telephone system

Filed: 1962-10-19
Abstract: 963,319. Automatic exchange systems. STANDARD TELEPHONES & CABLES Ltd. Oct. 19, 1962 [Oct. 25, 1961], No. 39656/62. Addition to 953,895. Heading H4K. In an arrangement comprising a plurality of cascaded cross-point matrices, in which marking of an input to the first of the matrices initiates a search over all paths extending towards outlets of the last matrix, one of which is marked, arrangements are provided to restrict the search only to those paths which can effect connection to the desired outlet. As shown, an interstage line such as 55 cannot be searched unless it is enabled by potential applied over a gate such as 68. In the case of an incoming call, connection between a line such as 10 and a preallotted link #1 is effected over a primary matrix 50 and an intermediate matrix 51. When a link is allotted, closure of contact 63 marks the link and contact 69 marks all primary-intermediate lines such as 55, capable of effecting connection to the link. The marking voltage applied to the incoming line is a voltage steadily rising from 0 to +18 v. The link marking voltage is -18 v. as is also the potential applied to the lower plates of condensers 79. Marking of a line such as 55 lowers its potential from a small value to -18 v. When an incoming line is marked, all the crosspoints D (which may be PNPN diodes) connecting it to marked lines such as 55 start to break down. The first to do so immediately raises the calling line side potential so that the others cannot fire at this time. Moreover; the rise in potential of line 55 then causes an intermediate cross-point D6 to fire to complete the connection to a link #1. The current thus flowing through the diodes holding them conducting. The potential on the line 55 then changes to between 0 and -4 v. which should be sufficient to prevent diodes connected thereto from firing. However, to prevent unwanted connections to a busy line in marginal conditions, guard circuits 105 are provided in which the condenser resistance combinations CR are connected to the line via PNPN diodes GD. Point JV is at -10v, so that if D fires and the potential of 55 rises, diode GD fires and condenser C charges. When C is charged diode GD losses current and cuts off. This now enables condenser 79 to charge up and so cut off D, whereupon other diodes connected to line 10 are permitted to fire provided they give access to paths marked by the link. When the wanted number is registered in the link (say 30), the multiple 95 is marked by means not shown and also enabling potential is applied to lead 89. This is applied via gates 84, 73, 90 to mark all possible paths back to the link. A search is made as before through these paths until one is completed back to the link, whereupon the connection is completed.
