Title: Improved means for controlling the fuel supply of an engine
IPC: F02D29/00
Filed: 1957-03-28
Abstract: 805,459. Regulating. CUMMINS ENGINE CO., Inc. March 28, 1957 [April 23, 1956], No. 10160/57. Class 7(6) [Also in Group XXVI] In an engine assembly comprising an engine 21 driving mechanism 19 such as a hydraulic torque converter, the supply of fuel from an engine driven pump 24, Fig. 6, through a pipe 53 to a pipe 30 leading to the injectors is controlled by two valves 72, 92 in series, the valve 72 being controlled in response to an operating characteristic of the mechanism 19 and the valve 92 in response to an engine operating characteristic, and a by-pass conduit 154 supplies idling fuel directly from the pump 24 to the valve 92 without passing through the valve 72. As shown, the valve 72 is controlled by a governor 114 driven from the output shaft of the torque converter 19 and acts to reduce or cut off the fuel supply when the converter output shaft overspeeds, and the valve 92 is controlled by an engine driven governor 64. During normal load conditions a recess 85 in valve 72 connects the inlet orifices 74, Fig. 9, to the outlet orifices 77 from which fuel flows to the inlet orifices 100 of valve 92 a recess 96 in which permits the fuel to flow to outlet orifices 101 and thence to the injectors. If, on a sudden decrease in load, an overspeed of the converter output shaft occurs, valve 72 is moved to the right to close orifices 74, cutting off the main fuel supply and connecting the outlets 77 to an exhaust 81. When the engine speed drops to idling the valve 92 opens the idling by-pass 156 leading directly from the pump 24, whereby sufficient fuel is. supplied to keep the engine idling regardless of the action of valve 72. In Fig. 1, the casing 54 containing the valve 72 is combined with the casing 70 of valve 92 and the governor springs are controlled by levers 124 and 151. In a modification, the casing 54 is mounted on the converter 19. The invention is also applicable to engines driving an electric generator or a pump, the valve 72 being controlled respectively by the generator and pump outputs. Alternatively valve 72 may be controlled by the temperature of a mechanism driven by the engine.

Title: Improved method and apparatus for photo-electric sound reproduction
IPC: G11B7/00
Filed: 1935-04-02
Abstract: 441,437. Optical sound-reproducing apparatus. CRUDO, F., 245, Defensa, Buenos Aires. April 2, 1935, Nos. 10245 and 10246. Convention dates, April 14, 1934. [Class 40 (ii)] [See also Group XX] In photo-electric apparatus for repro ducing sound from a record which is in the form of a rectangular or like sheet having discontinuous soundtracks, and which is mounted on a rotary cylindrical carrier so that the ends of the sound-tracks are juxtaposed at the meeting edges of the record to form a substantially continuous track, means are provided for preventing any noticeable undesired effect when the junction of the edges of the record passes the light beam. Such means operate at each revolution of the cylinder, momentarily to intercept, partially or wholly and preferably in a gradual manner, the light falling on the photo-electric cell, or to intercept the operation of the photo-electric current. The means for intercepting the light may also serve to hold the record in position. Fig. 1 shows the manner in which the record sheet 1 is mounted on a rotary carrier 2, the edges of the record meeting at 3. Soundreproduction is effected in known manner by means of reflected light. One method of carrying out the invention consists in forming on each of the adjacent ends of the soundtracks suitable markings, which may be wedgeshaped as shown at 4 in Fig. 4, or may be of uniform width and graded intensity. In another method, an electromagneticallyoperated shutter 14, Fig. 8, is interposed between the exciter lamp 18 and the optical system 19 which transmits the light for reflection from the record 1 to the photo-electric cell 20. The shutter, which is wedge-shaped, is moved into the path of the beam each time the junction 3 reaches the point P where reproduction is effected. Movement of the shutter is caused at the proper instant in every revolution of the cylinder 2 by an electromagnet 9, energized by the closure of a switch 16 by a device (not shown) on the cylinder. The switch may, in an alternative arrangement, shortcircuit the secondary winding of the transformer to which the photo-electric cell is connected. Fig. 11 shows how the record 1, positioned between stops 33 on the cylinder 2, may have its meeting edges held down by a spring-controlled rod 30 which is pivoted at 32 on the cylinder. The rod 30 is suitably coloured, and masks the effect of the junction on the sound-reproduction. Various modifications of this arrangement are described and shown. Thus, instead of the plain rod 30, a screw-threaded rod, a helicoidal spring, one or a pair of toothed rods, or a translucent prismatic bar may be employed, so that a gradual scattering of the light at the junction is effected.

Propelling, steering, and manoeuvring by vibrating plates or fins.-A submarine of the type propelled and manoeuvred by a series of vibrating fins has the fin-actuating mechanism so arranged that the stroke of the fins and the plane of vibration may be varied. The fins f, Fig. 2, preferably eight in number, four at the bow and four at the stern, are vibrated by means of a pair of slotted levers c passing. through stuffing-boxes, as described in Specification 5399/91, and oscillated by cranks t rotated by an electric motor g acting through spur gearing h, i and bevel-gearing p, q. To enable the plane of vibration to be varied, the levers o and cranks t are mounted in a casing a, normally pressed against the sides of the vessels by hydraulic presses and adapted to be rotated by an electrically-driven worm engaging a worm-wheel u on the outside of the casing. By this means, the plane of vibration may be completely rotated, so that the bow fins may vibrate in opposition to the stern fins and thus hold the vessel poised. To vary the amplitude of the vibration, the cranks t and bevel-gearing p, q are mounted on a member e adapted to be moved axially in the casing a. The member e engages a square guide-pin d and, exterior'to the casing a, is provided with a series of ring-shaped teeth adapted to co-operate with an electricallydriven spur-wheel m for moving the member e.

Abstract: 325,734. Meyer, G. April 4th, 1929. Vaporizers, external.-Crude oil for use in a direct injection engine is heated by the cylinder cooling water. to which additional heat is supplied from the exhaust gases. Cooling water is conveyed through pipes 18 to a jacket 19 around an exhaust pipe 25 in which is located a coil 26 through which water is circulated from a branch passage 22 leading from one of the pipes 18. The coil 26 extends to the interior of a heat-insulated fuel feed pipe 11, water flowing through a pipe 31 to level-regulating and main tanks 2 and 1, through coils 34 and 36 respectively and finally via a pipe 37 to rejoin a main outflow pipe 41. Fuel heated in the pipe 11 is conveyed through a pipe 12 to an engine supply pump x. The water flowing through the heater may be regulated by a cock 38. The fuel pipe 11 is given a slight upward inclination towards the tank end to permit the escape of gas or air bubbles through the pipe 10 to the top of the tank 2. Light fuel for starting the engine is supplied from a main tank 3 through a level-regulating tank 4, the pipe leading from the tank 4 into the common feed pipe 11 being provided with a cock 99 to cut off or regulate the supply. At starting, a mixture containing 50 per cent of each oil is used. The tanks 2 and 4 are each fitted with a filter 15 and with a float-controlled valve 16 to regulate the supply from the main tanks 1 and 3, the smaller tanks being so arranged that the fuel level therein is always below the valve controlling the fuel inlet for the cylinders, to prevent fuel entering the engine when at rest.

Filed: 1975-03-14
Abstract: 1508012 Embossing tufted pile ARMSTRONG CORK CO 14 March 1975 [14 March 1974] 10803/75 Headings D1P and D1S A synthetic tufted carpet material has an embossed pattern effect created thereon by application to the tufted pile face surface yarns of a latent solvent embossing agent in solution in a predetermined concentration in the desired embossing pattern in a quantity thoroughly to wet the yarns in the pattern for at least 35% of the length of the portion projecting above the backing, and subsequently steaming to shrink the treated yarns and develop the embossed pattern effect. The surface yarns comprise a major proportion of synthetic semicrystalline, oriented, thermoplastics fibres such as nylon 6, nylon 66, acrylic or polyester fibres. The latent solvent solution is a solution e.g. in water of an embossing agent for the fibres e.g. zinc chloride or resorcinol for nylon fibres, phenol for polyester fibres or ethylene carbonate for acrylic fibres. The concentration at which the solution is applied is arranged to be such that the concentration on the pile yarns, just prior to steaming, is less than, but more than 40% of, the "destructive concentration" of the solution at which the fibre structure would be destroyed by the latent solvent upon subsequent steaming. The carpet may be dyed and/or printed before and/or simultaneously with the embossing treatment, preferably by design elements which are in registry with each other and with the embossing pattern. After steaming, the carpet is washed, cleaned and dried. The backing of the carpet is of a different material from the surface yarn e.g. a polypropylene, which is unaffected by the latent solvent solution.
