Class 20(3) The vertical slats of a venetian blind arranged to traverse the window horizontally are pivoted simultaneously about their respective vertical axes by individual mechanisms at one or both ends of each slat and operated from a common shaft 46 and comprises a hook 24, Figs. 4, 9, engaging the slat at one end has mounted upon it slidably but non-rotatably a worm gear 32, Fig. 9, supported as on a shaft 26 in a bore in a housing 38 with each extremity of the hook projecting therefrom, the drive shaft 46 projecting through a second bore in the housing communicating with the first bore and having slidably but non-rotatably mounted thereon, a worm 48 in gear with the worm gear 32 and the housing 38 is provided with supporting means, e.g. in the form of friction rollers 60 on each side of the housing for supporting it in channel guides 63, Fig. 8, at the top or the bottom of the window frame. These guides particularly in the bottom of the window frame have additional flanges 65 to hold the rollers down. The hook 24 may move relatively to the housing 38 by compressing spring 36 to hold the slat taut and compensate for slight variations in slat length. Rotation of the shaft 46 as by a chain and pulley mechanism rotates the worm gear 32 and hence the slat 24. The housing 38 is in two parts riveted together and is provided with a head 110 on a post 112 accommodated in a long slot 108 of a tie rod 104, Fig. 8, on one side and a short slot 106 of a tie rod on the opposite side, the tie rods being similarly coupled at their other ends to other housings 38. The outermost housing 38, as regards the traversed position of the blind has a traversing bracket 96, Fig. 4, mounted thereon and spaced therefrom along the shaft 46 which passes through a nylon bushing 98 in the bracket and a traversing cord 90, passes through a bore in the bracket, beads 92 on one of the cords acting as stops to the bracket to cause the latter to move with the cord. In the case of all the housings 38, the cord 90 passes through an eyelet 88, Fig. 9, on the housing. When the cord 90 is pulled to retract the slats from the traversed position shown in Fig. 8, into the nested position the left hand housing and traversing bracket (not shown) moves to the right and takes the ties with it sliding relatively to the right hand side housing until the two housings collide and move together to collide with the next and so on until the whole blind is retracted. On pulling the cord 90 in the opposite direction, the housings separate away in succession and move in relatively separated positions to the traversed position of the blind.

Title: Improvements in processes for the manufacture of iron
IPC: C21B5/00
Filed: 1921-07-14
Abstract: 191,764. Franchot, R., and McElroy, K. P. July 14, 1921. Extracting.-In a process for manufacturing iron of the type in which a portion of the hot reducing gases is diverted from the blast furnace at a level below the usual top outlet, which portion may be cooled and returned in part to a higber zone cf the furnace, the volume of gases diverted is so adjusted in relation to the gases ascending the shaft that either a substantial net deposition of carbon is obtained within the shaft or the volume ratio of CO to CO2 in the top exit gases is not greater than 60 to 40 or the temperature of the top exit gases is not greater than 250‹ C. By regulating the proportions of the ascending and diverted gases the temperature of the blast may be reduced, its volume increased to an amount exceeding 70 cubic feet per pound of carbon charged into the furnace, and the accumulation of salines in the hearth prevented, these being carried away by the diverted gases. The volume of gases diverted may be increased to lower the temperature and increase the ratio of CO2 in the top gases and decreased to raise the temperature and the CO2 ratio. Some of the heat obtained from the diverted gases may be used to heat the air blast, or for other purposes.

Title: Improvements in and relating to the synthesis of 1, 4-dichloro-2, 3-butanediol and butadiene dioxide
IPC: C07C31/42
Filed: 1955-07-04
Abstract: 1,4-Dichloro-2,3-butane diol is produced by a process comprising hydrolysing 1,4-dichloro-2,3-epoxybutane by heating it with water in the presence of an acidic hydrolysis catalyst.  The diol may then be dehydrochlorinated by reacting it with a finely-divided alkali hydroxide in a water-immiscible ether to produce butadiene dioxide. Preferably the 1,4-dichloro-2,3-epoxybutane is hydrolysed in the presence of water and a water-immiscible organic ether in which the 1,4 - dichloro - 2,3 - epoxybutane is substantially soluble, such as dioxane, tetrahydrofurane, dimethyl ether, ethyleneglycol dimethyl ether and diethylene glycol diethyl ether.  The hydrolysis step is preferably carried out at a temperature in the range 50 DEG  to 175 DEG  C. and the preferred hydrolysis catalyst is sulphuric acid. Suitable ethers for use in the dehydrochlorination step are, for example, diethyl ether, n-butyl ether, isopropyl ether and n-hexyl ether.  Preferably an anhydrous salt, e.g. sodium sulphate, magnesium sulphate, potassium carbonate or calcium sulphate, is added to the mixture in the dehydrochlorination step.  The 1.4-dichloro-2,3-epoxybutane used as starting material may be obtained by chlorinating butadiene and treating 1,4-dichloro-2-butene obtained with peracetic acid. In the examples, 1,4-dichloro-2,3-epoxybutane is added to a mixture of dioxane and concentrated sulphuric acid and the mixture is heated to give 1,4-dichloro-2,3-butanediol; the 1,4-dichloro-2,3-butanediol is added to diethyl ether and the mixture is treated with potassium or sodium hydroxide to give butadiene dioxide.

Abstract: 418,812. Valves. MOTTERSHALL, W. H., 141, Ranleigh Avenue, Toronto, Ontario, Canada. June 30, 1934, No. 19354. Convention date, March 20. [Class 135.] A ventilator valve attachment for admitting a constant air flow limits automatically the amount of air flow through a vent pipe in either direction when subjected to increased air pressures. An open-ended casing 2 is secured to the end of a vent pipe 1, and holds, by a cross piece 6 and spring clip 7, a spindle 5 on which is freely mounted a valve 9 of inverted cup-shape. Springs 12 and 13 limit the motion of the valve 9, the bushing 10 of which has an elongated orifice 11 through which the spindle passes, with the result that an upward current of air rotates the valve which assumes a balanced position. Excessive air movement up or down forces the valve to compress either the spring 12 or 13 and causes it to close the upper or lower end of the casing. The device is removed by disengaging the clip 7 and drawing down the spindle 5 and its attached parts.
