Title: Improvements in fire extinguishing apparatus
IPC: A62C13/70
Filed: 1929-07-09
Abstract: 315,317. Pyrene Manufacutring Co., (Assignees of MacGregor, P. G.). July 11, 1928, [Convention date]. Direct gas-pressure apparatus, non-automatic. -In a fire-extinguisher of the kind in which liquid is ejected from a container by compressed gas from a normally sealed capsule, the cage which supports the capsule is partly formed by rods which are movable so as to control a valve which normally excludes the liquid from the discharge pipe. As shown, the container 10 is held, for example on an aeroplane, by a bracket 11 consisting of a divided ring 14 and a bracket 16 formed with an aperture to receive a threaded boss 18 on the container. The cover 20 of the container has an opening receiving a ring 21 which carries arms 22 to support the capsule 40. The arms 22 carry a yoke 23 formed with a passage-way 26 and with arms 24 which guide rods 25 forming part of the capsule cage. A dip tube 26<1> and a discharge pipe are connected to the respective ends of the passage-way 26. The dip tube carries at its lower end a tubular member 28 formed with a valve seat and a depending skirt 29. A valve head 30 guided within the skirt is carried by the rods 25 and is forced into closed position by a spring 33. Screwed into the ring 21 is a fitting 42 formed with a cam chamber 43. Slidable within the fitting is a plunger 45 having its head 46 engaged by a cam 57 operated by a shaft 56 with a readilyremovable hand-wheel 60. The plunger carries a pin 50 for piercing the gas capsule and a member 48 engaging the upper ends of the rods 25. When the cam is operated by the hand-wheel, or from a distant point by a lever 70 and a wire, the capsule is opened, and the valve 30 is depressed by the rods 25, permitting entry of the liquid to the dip tube. In a modification, Fig. 11, a cam member 74 is rotated by a vertical shaft 79 and is formed with two cam slots 75 which engage a pin 78<1> on the plunger 78 carrying the piercer 50 and member 48. The plunger is held from rotation by slots in the fitting 72.

Title: Insulated conductor construction for use in electrical circuits
IPC: H01B13/10
Filed: 1944-10-31
Abstract: 583,455. Moulding electric conductor coverings. ABBOTT, C. W. Oct. 31, 1944, No. 21266. [Class 87 (ii)] [Also in Group XXXVI] Electric conductors are encased in strips of flexible non-vulcanizable insulating thermoplastic material, heat and pressure being applied to those portions of the strips which are brought into engagement with each other lengthwise of the conductor, so that these portions are bonded together while the material which encases the conductor is not bonded to it. Spaced parallel conductors 36, Fig. 1, may be moved axially through guides 52 and cooling means 101, while strips 28, 29 of the thermoplastic material are moved through heated presser means, such as co-acting pairs of rotary discs 26b, 27b, Fig. 9a, not necessarily equally spaced, supported on drums 26, 27. The drums are preferably hollow, the interior being supplied with a heating medium, such as steam or heated oil, through valve-controlled conduits, and thermostatically operated means may be used to govern the rate of flow of the heating medium through the drums. The drums may be vertically adjustable toward or away from one another so that the faces 26c, 27c of the discs can be spaced apart by a distance approximately half the sum of the thicknesses of the strips 28, 29. The strips may be preheated by the heat from the drums and passed through fluting devices 34, 35 so that the strips are corrugated to fit over the conductors 36. The thermoplastic material is preferably heated by the drums to a temperature slightly below its melting point, so that the portions pressed into engagement with each other by the discs 26b, 27b become bonded together, while the remaining portions do not adhere to the conductors. The multiple conductor structure may then be passed through heated slitters 93, or if left in band-like form to be slit later by a knife, the faces 26c, 27c of the discs may be grooved 26g, 27g, Fig. 17, so that lines of weakness are left, along which the insulation can be slit. The discs 26b may be slotted, as at 26p, Fig. 26, while the discs 27b have projections 27p so that a series of holes is punched to facilitate separation of the conductors. The strip 28 may be left substantially flat while the strip 29 is pressed about the conductors, and, if desired, the resultant structure may be slit into pairs, each pair being folded longitudinally and the ends 28k, Fig. 24, united into a junction 28m by being passed between rollers 105 and a heated element 103. Instead of being passed through one pairof drums, the conductors may be passed through two pairs, one pair being hot to make the material sufficiently plastic, and the other cold to compress the strips and bond them together between the conductors.

[Also in Group XXII] A blade assembly for an axial-flow compressor, turbine or blower comprises an individual supporting ring for each row of blades and spacer rings secured in axial aligmnent between adjacent blade supporting rings and formed with annular projections partially overlapping the blade support rings. Each blade supporting ring is formed with a plurality of circumferentiallyspaced slots across the peripheral face thereof, each slot being of such a depth as to extend into the portion of the ring underlying the annular projections of the adjacent spacer rings, the blades having root portions filling the slots so that the blades are retained in position radially by the projections. The invention is shown applied to an axial-flow compressor comprising a stator casing 16 and a rotor 18. The stator comprises a pair of end rings 12, 14 between which are disposed blade-carrying rings 20 and intermediate spacer rings 22, the assembly being held together by longitudinally-extending tie-bolts 37. The rotor likewise consists of a pair of end members 56, blade-carrying rings 40 and spacer rings 50, the assembly being held together by tie-bolts 58. Stub shafts 66 secured within the members 56 are rotatably supported in the stator end rings 12, 14 by means of bearings 68. A driving pulley 74 is secured on one of the stub shafts. Air enters through inlets 76 to the annular passage 78 and is delivered from the annular passage 80 through the outlet 82. The rotor bladecarrying rings 40 are of T-section, as shown in Figs. 5 and 6, having annular grooves 42 on their outer surfaces. They are also formed with circumferentially-spaced blade receiving slots 44 the depth of which is greater than that of the annular grooves 42. Blades in the form of curved plates 46 are mounted in the slots 44 the leading and trailing edges of the blades then being machined away so that the root end of each blade is of T-shape with the projections of the T disposed in the slot 44 inwardly of the annular grooves 42. The spacer rings 50 are also of T-section, the projections of the T engaging in the annular grooves 42 whereby the blades are held securely in position. Packing rings 54 are disposed between the bladecarrying and spacer rings. The stator blades 30 are formed and mounted in a similar manner. The radial width of the working fluid annulus is uniform from inlet to outlet and the number of blades in each circumferential row is the same, but the angular setting and curvature of the blades in each row varies from the inlet end to the outlet end. The curved plates constituting the blades are all of the same curvature, the plates being deformed to the correct curvature when entered in the curved slots 44.

Abstract: 666,686. Screw conveyers. BAUGHAN, H. P. Jan. 31, 1948. [Aug. 7. 1947] No. 21490/47. Class 78 (i). An axially reciprocating mechanism, for conveying solid material along a channel C, comprises a propelling screw or helix F and means G for positively moving said screw or helix axially along the channel in one direction substantially without rotation in order to feed a charge of the material and for rotating the member whilst positively moving it in the other direction, the direction of rotation being such as to "unscrew" the member from the charge. Figs. 1, 2. Coal is fed from hopper A to fire grate D along conduit C by spiral F which, together with pusher E, is fixed on its shaft, which shaft is journalled in bearing J and is fixed to driving shaft G formed with a groove of the same pitch as the spiral F. In groove K slides the projection N of inner clutch member R, the outer clutch member M of which is secured to fixed frame B and rollers L roll between the two clutch members. When the driving shaft G and screw F axially are advanced the inner clutch member is caused to rotate clockwise but no rotation of the shaft and screw occurs. When the said shaft and screw are axially retracted are the rollers L and inner clutch member K are jammed and the shaft and screw are caused by the projection N working in the groove to rotate clockwise. An additional one-way clutch may be included consisting of an inner member R secured to the shaft, an outer member S having a projection T working in a straight groove in groove P, and rollers between. These are arranged to prevent rotation of the screw when it advances and to permit rotation of the screw when it retracts. The screw shaft may be integral with the driving shaft G, the ram E may be omitted; the screw need have no shaft, and its pitch may be different from that of the groove G so as to move the fuel on the backward stroke.
