Title: Improved means for filling two containers alternately
IPC: B67D7/16
Filed: 1926-09-29
Abstract: 287,589. Shell-Mex, Ltd., and Lawson, J. Sept. 29, 1926. Liquid meters.-In a two-chamber apparatus having a pressure-operated plug cock, the plug cock is moved initially by a rocking member connected to two pistons acted on alternately by the supply, and the motion is completed by a spring. In the form shown in Figs. 1-3, the rocking member 6 is a saddle piece mounted on an extension 8 of the plug cock 9, and the extension 8 carries a valve with heads 14, 15 alternately closing ports 10, 11 and thus controlling access of the supply to the cylinders 1, 2 of the pistons 3, 4. When the piston 3 is raised, the parts 6, 8, 9 move together until a spring 24 is moved past its dead-centre position; the spring then acts to move the parts 8, 9 further, so that the port 10 is closed, the port 11 is opened, and the cylinder 1 is put to exhaust through a port 31 and a groove 26 leading through a passage 30 to the supply reservoir. 'The grooves 26 may extend through a partition to a compartment 27 so that the cock is not subject to end pressure, the compartment serving also to accommodate the spring and its connections. Indicating mechanism may be operated through a lever actuated by shoulders 8<a>. In another form, the pistons are disposed as shown in Fig 8, and are connected to a sleeve 36 having a projection 36<b> adapted to engage one of a pair of projections 37, 38, Fig. 7. on a crank 23, Fig. 4, to which one end of the spring 24 is secured. The crank is connected by a projection 51 to the cock 9, and has another pair of projections 40, 41 serving to operate a valve 43 through a projection 42, the valve 43 governing the supply to or exhaust from the cylinders 1, 2. The exhaust chamber 49 is connected to the reservoir by a pipe 50, and may be connected to the air system of the apparatus by a passage 53, so that movement of the pistons is prevented until a chamber is empty. In order to balance the cock 9, it is provided with a recess 54 connected to the supply port 56 by a passage 55, and a chamber in its rear end connected to the passage 55 contains a piston 59 abutting against an adjustable screw 62; a spring 60 is also provided. Projections on the cock 9 may operate indicating mechanism, by acting on a cap 65 closing one end of a flexible metallic tube 66 enclosing a rod 68 connected to a lever, or the projections on the cock may be replaced by a cam 70, Fig 13, adapted to operate a sheath 71 having a part fitting over the cap 65. Specifications 287,268, [Class 106 (v), Measured quantities &c.], 297,764, [Class 135, Valves &c.], and 297,863, [Class 122 (v), Stuffing-boxes &c.], are referred to.

Abstract: 323,248. Godfrey, E. L. Aug. 22, 1928. Oil stoves.-In connection with a frame or enclosure for horticultural, incubation, propagation, or similar purposes, and external heating-apparatus therefor, provision is made for angular adjustment and location of the housing containing the heating apparatus in relation to the enclosure proper and for fixing it rigidly in its adjusted position. The housing c for the heat generator may be open at the bottom and may be provided with an oil reservoir a fitted with a burner f and mounted on trunnions d so that it may rest on level ground when the housing c and frame b are inclined transversely. The reservoir a is held in adjusted position by means of a slotted arm a<1> and a nut a<2>. A hopper-like part g conducts the fumes &c. from the burner f into a flue h passing through the upper front part of the frame or enclosure. The flue may be rotatable for adjusting the part g. It has an adjustable upturned outlet fitted with a cowl i. Perforations may be provided for the escape of condensed moisture. The flue may pass through several frames or enclosures arranged side by side, and may rise gradually towards the outlet. The frame may be shaped or tilted to correspond with the inclined flue. The housing c may be furnished with air inlets, with a removable top j, and with a side shutter k giving access to the burner &c. The burner f and two filler caps m may be mounted on a disc l which may be rotated to bring them into position for trimming the wick, filling the reservoir &c. To allow of tilting the frame b to catch the rays of the sun, the flue h passes through an opening in a detachable housing part n which is slotted to receive a stud p fixed on the frame, the parts being secured in position by a nut q. The part n is interchangeable with a part r carrying the shutter k, so that the housing may be applied to either end of the frame. A window may be provided in the shutter. The heating-apparatus may form a self-contained unit for application to existing frames. The flue h may lead into an outside conduit u, Fig. 9, from which projects a tube v leading into a perforated cylinder wand provided with a baffle x. A U-shaped cover y, open at top and bottom, may be placed over the cylinder w to prevent side draughts, and an open-fronted cylinder z may surround the cover y.

Abstract: 787,485. Furnace charging machines. SOC. D'EXPLOITATION DES ETABLISSEMENTS PAINDAVOINE FRERES. Aug. 22, 1955 [June 8, 1955], No. 24110/55. Class 51 (2). In a furnace charging machine of the type incorporating a charging arm mounted on a carriage adapted to move it in and out of the furnace, the arm 13 carrying a charging box 14 is mounted for vertical movement in a framework 1 suspended from the carriage 2 running on a gantry 3. The arm is pivoted in a front frame 17 and suspended from a rear frame 18 by pivoted links 21 and is rotated by conventional mechanism 15. Vertical movement of the frames 17 and 18 is through racks 11 and 12 attached thereto and respectively actuated by pinions 9 and 10 driven from a motor 7 through reduction gearing 8. The latter is shown in detail in Fig. 2, which shows the motor 7 driving a shaft 7<SP>1</SP> from which the drive for the front frame 17 is through a pinion 22, a gear-wheel 23, a pinion 26 associated with a free-wheel 23, a pinion 26 associated with a free-wheel 24 and a gear-wheel 27. When the arm 13 or the charging box 14 encounters an obstacle on the downward movement of the frame, the free-wheel 24 is brought into action, the pressure' at which this occurs being varied by a plate 25 adjustably pressed by springs against the wheel 24. The rear frame 18 is operated from the shaft 7<SP>1</SP> through an electromagnetic clutch 28, a pinion 32, a gear-wheel 33, a pinion 34, and a gearwheel 35, so that when the clutch is out the rear frame is still, the arm 13 then being capable of vertical oscillations about the pivot 20 by means of movements of the front frame 17. The control cabin 5, mechanism 6 for rotation of the framework 1 about a vertical axis and motor 7 with its associated gearing 8 are all mounted on the said framework 1 so that they are not subject to vertical movements. A counterweight 16 is attached to the upper end of the front rack 11.

Title: Process for the production of hydrazonium salts
IPC: C01B21/16
Filed: 1958-07-31
Abstract: <PICT:0839819/III/1> Hydrazonium salts are prepared by acid decomposition of aqueous solutions containing the reaction products of hydrazine hydrate and acetone, wherein distillation of the acetone liberated gradually by the action of the acid is effected in stages, each of which is preceded by a delay period interposed to allow for the liberation of an amount of acetone to be distilled off in the next succeeding distillation stage.  Aqueous hydrazine/acetone solution and an acid, e.g. sulphuric acid pass in stoichiometric proportions from storage vessels 1 and 2 respectively into mixing vessel 3 at the rate for the total mixture of 1 litre/hour. Hydrazonium salt solution freed from acetone in proportion of 5-10X the volume of the mixture is charged into vessel 3 from one of the final delay vessels 6 by pump 4.  The resulting aqueous mixture is charged continuously to the upper fractionating column 5 operated under such conditions that some acetone, possibly containing a little hydrazine, distils off and is collected in a receiver.  The aqueous solution, partially free from acetone, collects in an upper delay vessel 6 until sufficient quantity is present to pass through a second fractionating column 5 where further quantities of acetone formed during the delay period are removed by distillation.  The process may be repeated several times as indicated in the Figure, an aqueous solution of hydrazonium salt free from acetone collecting finally in sump 7.
