Title: Improvements in and relating to domestic and central-heating boilers
IPC: F24H1/22
Filed: 1943-10-15
Abstract: 571,670. Hot-water boilers. WATTS, A. J. Oct. 15, 1943, No. 16993. [Class 64 (i)] A domestic or central-heating boiler comprises a bottom 2, side and back walls 4 and an upwardly and rearwardly-inclined top 3 surrounding a combustion chamber 1, the side and back walls and the top being formed as water spaces communicating one with another ; the bottom may also be hollow to constitute a water-space or, alternatively, covered with firebrick 2a. Solid fuel is supplied to the combustion chamber from a hopper 13 which is mounted on the boiler top and has a discharge 15, fitted with a shut-off member 36, adapted to register with an opening 16 in said boiler top, the opening being continued in the form of an adjustable pipe 17, 17a which terminates above a domed water-cooled fuel-supporting member 19 located on the bottom of the boiler above an apertured plate 20. This plate 20 has a pipe extension 28 to which combustion air is supplied to the boiler either from a thermostatically-controlled fan or blower 29 or from an opening 33, the latter being closed by a light flap valve 31 when the fan is in operation but opening under the action of the natural draught through the boiler when the fan is at rest, the air passing to the combustion chamber through slots 21 in the fuel-supporting member 19 and also through an air pipe 24 which extends from the latter and terminates in a horseshoe-shaped apertured pipe 25. In order to provide, if desired, a supply of gaseous fuel to the boiler, the air supply pipe 28 is fitted with a gas supply pipe 34, which pipe may also be used for supplying water or steam to the combustion chamber 1 when coke is being burnt. The combustion gases leave the chamber 1 through an aperture 7 and pass downwardly through a central vertical flue 39 and then upwardly through side flues to an outlet 43 leading to a chimney, the said flues 39 contacting the rear face of the rear boiler wall, and one of the side flues may be provided with an opening 45, normally closed by a cover-plate, over which a cooking oven may be secured.

Title: Improvements in or relating to electrical measuring apparatus
IPC: G01R5/14
Filed: 1930-06-02
Abstract: 359,992. Current and pressure meters. REICH, E., 16, V÷r÷smarthy-U, Budapest. June 2, 1930, No. 16995. [Class 37.] An ammeter is constructed to measure direct or alternating current flowing in a conductor without necessitating a break of the conductor or the attachment of the ends of the conductor to the instrument, one or more cores of magnetic material projecting from the casing of the instrument being adapted to be introduced into the magnetic field of the conductor carrying the current to be measured. A housing 1, Figs. 2 and 3, of insulating material contains the moving system, which comprises a soft iron segment 6 rigidly mounted on a shaft 8 carrying a pointer 7 and damping-vane 9. Projecting rearwardly from the casing 1 are two iron plates 3 which can be placed on each side of the conductor 4 carrying the current to be measured. The inner ends of these plates are bent into arcs forming polepieces 16 adjacent to the segment 6. Magnetic flux due to the current in the conductor 4 thus causes a deflection of the segment 6 against the control of a spring 11. A handle 13 is rotatably mounted on pins 14 so that when the instrument is out of use the handle can be folded over into the position shown in dotted lines. The plates 3 may be hinged so as to fold into the position shown in dotted lines. A sliding stop may be arranged on the plates 3 for positioning the instrument with relation to the conductor 4 and a scale corresponding to different positions may indicate the range. For measuring voltages or relatively small currents, an insulating casing 20, Fig. 9, is arranged on the iron plate 3 and contains pairs of coils 18, 21, and a resistance coil 22 connected to terminals 34 and the contacts of a push-button switch (not shown), so arranged that either of the pairs of coils 18, 21 may be connected in circuit for measuring different ranges of current values, or the coils 21 alone or in series with the resistance coil 22 may be connected across the mains for measuring different ranges of voltages. The casing 20 may be removable from the plates 3, and the coils may be permanently connected to the supply by flexible leads and brought into position on the instrument only when required.

Title: Improvements relating to baling presses
IPC: B65G53/60
Filed: 1956-06-04
Abstract: 793,087. Baling-presses. LINDEMANN, W. June 4, 1956 [Oct. 1, 1955], No. 17220/56. Class 94(1). A baling press for fibrous material includes a press box which is charged by material entrained in air passing through the box. In one embodiment air is drawn by suction through perforations 7 in the box 1, air and material entering through conduits 8. Initial compression of the material by the air may be improved by applying intermittent pressure air on the inlet side in addition to the suction. The charge is compressed by a ram 9, tied and removed through a side door (not shown). In another embodiment, two open-ended boxes 13, 14 rotate about an axis I between a ram 23, and air inlet and outlet connections 15, 19. A box remains between connections 15, 19 until filled and is then rotated to rest between the ram 23 and a chamber 24. Each box has a loose bottom 25 which rises with the ram during compression of the material into the chamber 24. The material is tied and removed through a side door in the chamber.

Filed: 1925-07-06
Abstract: 250,892. Sharp & Dohme, (Assignees of Dohme, A. R. L.). April 16, 1925, [Convention date]. Alkyl resorcinols, such as propyl, butyl, amyl, hexyl, heptyl, octyl, dodecyl, isobutyl, isoamyl, and isohexyl, are prepared by stirring and heating the corresponding acyl resorcinols with zinc amalgam and hydrochloric acid. the amount of zinc amalgam being not substantially in excess of 2.5 times the weight of ketone, and the temperature being preferably about 105‹ C. The acyl resorcinols may be prepared by the process described in Specification 250,893, the oil obtained by a single vacuum distillation of the condensation product being in most cases sufficiently pure. In an example, resorcinol is condensed with caproic acid in presence of zinc chloride at 135- 145‹ C., water added to the product and the oily layer washed and distilled in vacuo, the oily caproyl resorcinol being reduced at 105‹ C. with 2.5 times its weight of zinc amalgam and hydrochloric acid. The reduction product is washed with water, distilled in vacuo, and may be further purified by redistillation and crystallization from a mixture of toluene and petroleum ether. Specifications 219,922 and 224,913 are referred to.

Class 75(i) In a fuel combustion means for a gasturbine engine of the kind comprising a fuel injector assembly having a swirl chamber and surrounded by an annular element to define an annular duct for the passage of combustion air, the fuel injector assembly comprises a substantially conical external surface 30, Fig. 2, having a fuel atomizing orifice 27A at its apex, an internally conical shroud 29A separate from the annular element 33 and surrounding the surface 30 over part only of its axial length to define an annular passage 31 of conical form, and passage means, e.g. apertures 32 in the shroud 29A for tapping off part of the air flowing through the annular duct 34 into the annular passage 31 from which it emerges over part of the conical surface 30 extending beyond the shroud 29A for cooling and preventing the deposit of carbon on said surface. The orifice member 27 is secured to a swirl chamber part 26 by a nut 28, and a nut 29 integral with the shroud 29A holds the swirl chamber and orifice assembly against a body member 23 having a fuel supply passage 25. The nut 28 has a frusto-conical surface adjoining the frusto-conical surface 30 and of greater apical angle than the latter. The fuel injector is mounted in the divergent air entry duct 20 of a flame chamber 18 which contains the annular element 33 surrounding and shaped correspondingly with the shroud 29A to ensure a flow of cooling air over the latter. In an alternative construction the injector body 45, Fig. 3, contains a filter element 47 loaded by a spring 48 and bearing against a swirl plug 49. An orifice part 51 having a frusto-conical exterior surface 51A is clamped to the body 45 by a nut 52 having a frusto-conical surface 54A. A shroud is screwed on to the nut 52 and is formed with a frusto-conical part 55B.
