Abstract: 594,279. Open fireplaces. DUNN, W. E. July 18, 1945, No. 18385. [Class 126] [Also in Group XXIX] Means for operating an angularly movable damper of a domestic water heater, stove, &c. comprises a lever having a curved slot engaging a roller on an arm which is fixed to a spindle on the damper in such a way that the damper is caused to turn about the axis of the spindle when the lever is actuated. The mechanism is shown applied to a combined fireplace and water heater having front and rear combustion spaces 1 and 2 communicating at their upper ends with a common flue 3. The damper operating mechanism comprises a lever 10, the rear portion of which is disposed along one side of the water heater, to which it is pivoted at 11. The lever is cranked at its forward end and carries a rod 14 which projects through a vertical slot in the tiled surround, the extremity of the rod being fitted with an operating knob 15 arranged to move through an arc of large diameter so as to project as little as possible through the surround. The lever is formed with an enlarged portion in which is a curved camslot 19 of such a width as to engage a roller on the arm 16 which is fixed to the rod 5 carrying the damper 4. In operation, when the lever 10 is moved downwardly the cam-slot and roller co-act to turn the damper to uncover the upper end of the rear combustion space 2, the rear combustion space being closed by moving the lever in the reverse direction. The damper may be counter-balanced so as to be selfretaining in any position in which it is placed and a set-screw may also be provided to prevent the damper from completely closing the rear combustion space. Specifications 578,581 and 581,301 are referred to.

Filed: 1927-07-12
Abstract: 298,284. Imray, O. Y., (I. G. Farbenindustrie Akt.-Ges.). July 12, 1927. Anthraquinone vat dyes. - N: Bz<1>1-Benzanthrcnylpyrazolanthrones are obtained by the action of Bz1-halogenbenzanthrones on pyrazolanthrones; by alkali fusion they yield vat dyes ; different 'substances are produced according to the reaction temperature, those obtained at lower temperatures being regarded as analogous to dibenzanthrones, viz. N : Bz'l : 2 : 2<1>-benzanthronepyrazolanthrones. The dyestuffs so obtained may be halogenated or nitrated, and the nitro-compounds may be reduced to aminocompounds ; the dyes may also be oxidized, the oxidation products reduced to hydroxy-derivatives with bisulphites, and the latter alkylated. In examples, N : Bz<1>1-benzanthronylpyrazolanthrone is treated with alcoholic potash at 100‹ C. to give a blue, and at 160‹ C. to give a greenish grey to black vat dve. The former is chlorinated with chlorine gas or sulphuryl chloride in nitrobenzene to a dichlor-derivative, and with chlorine gas in' chlorsulphonic acid with an addition of iodine to a tetrachlor-derivative; brominated in glacial acetic acid or nitrobenzene, and the nitro-compound reduced with sodium sulphide; and oxidized with pyrolusite in sulphuric acid of 60‹ BÚ. or monohydrate at room temperature and at 50-60‹ C. respectively to two different oxidation products, which are reduced with sodium bisulphite in their sulphuric acid suspension and alkylated to give greenish-blue and grey olive dyes respectively. The product of alkali fusion of N : Bz<1>1-benzanthronylpyrazolanthrone at 160‹ C. is also nitrated in glacial acetic acid or nitrobenzene. Dyes are also prepared by fusion with alcoholic alkali at 100‹ C. of Bz<1>2-phenyl-N - : Bz<1>1-benzanthronylpyrazolanthrone, N : Bz'lbenzanthronyl-4-methylpyrazolanthrone, and 6<1>- nitro- or 6<1>-amino-N : Bz<1>1-benzanthronylpyrazolanthrone; the two last substances give the same reaction product. A dyestuff is also obtained by alkali fusion of N : N<1>-di-Bz1-benzanthronyl-1 : 9 : 5 : 10-dipyrazolanthrone with alcoholic alkali at 150 to 160‹ C. Specifications 1818/05, 254,742, 268,830, and 298,775 are referred to.

[Classes 69 (ii) and 135] In a radial-cylinder liquid-meter in which the distributing valve 5 is held on its seat bv the resultant of the pressure acting on the valve and on a compensating member 11, the latter acts through mechanism so that the valve seating pressure first decreases and subsequently increases as the difference between the inlet and outlet pressures of the meter increases. The meter is operated at the point of minimum seating pressure. In one form, Fig. 6, the resultant pressure on a compensating piston diaphragm &c. 11, is transmitted through a spring 34, lever 38 pivoted at 39, and crank-shaft 2 to the valve. As the pressure varies, a spindle 40 carried by the piston operates a bell-crank lever 42 to move the pivot 39 thereby varying the pressure on the valve. Fig. 9 shows a form in which two compensating pistons 11, 17 are employed. The pressure on piston 17 acts in opposition to a spring 14 whereby above a predetermined pressure the piston 17 rises and relieves the spring pressure on the valve. In a further form, the valve is held on its seat by a spring which is replaced by a compensating piston above a particular pressure.
