Spray burner; oil supply; flame deflectors.- In liquid-fuel atomizing and burning apparatus a compressor chamber D is provided within which is means adapted to induce a flow of fuel and air thereto, to atomize said fuel, and to compress the mixture of atomized fuel and air before delivery to the burner C of the apparatus. The compressor D is driven by an electric motor A, the two having a common shaft 1, and comprises an eccentric cylinder 2, Fig. 7, having three or more longitudinal slots 6 within which are radially slidable laminated vanes 7, said slots 6 being parallel to the axis and running the full length of the rotator 2. Oil is fed to the compressor chamber by means of a rotary pump E. Fig. 8. which comprises an outer cylinder 27, attached to the casing of the compressor D, provided with an oil-supply chamber 36 and a rotor 29 mounted on a shaft 28 keyed to the shaft 1. The rotor 29 is smaller than the chamber in which it rotates and is provided with a socket 31 for the reception of a slidable plunger 30 and coil spring 32 which abuts the inner end of the plunger. Projecting within the cylinder casing 27 is an adjustable lug 41 which forms a cam surface in connection with the plunger 30, the lug 41 being provided with a spring band 42 to form a smooth cam surface. The socket 31 is provided with an aperture 35 adapted to communicate with the chamber 36 when the pump is in the position shown, and with an outlet 40 when the plunger contacts with the cam 41. In operation, as soon as the electric motor A is switched on, fuel oil from a supply tank passes through a tube 26 to the fuel-supply chamber 36, and is then forced by the plunger 30 of the rotary pump E through the outlet 40 and communicating tube to a sight feed cup connected to the inlet 25 of the atomizer. Just before the oil enters the atomizer D air through an inlet 44 is mixed therewith, and the mixture after being thoroughly atomized is ejected under a high pressure through the outlet 8 to a nozzle 46 projecting into the burner C. The nozzle is constructed so that the mixed' fuel will be ejected in a cone-shaped spray, the fuel being ignited by a pilot burner 51, while the burner itself is provided with an air-supply pipe 54, an oil drum 54<a>, and a rotatable deflector 85. The apparatus is said to be specially applicable for use in maintaining the temperature of a building within desired limits, a thermostat being provided for operating an electric switch for automatically starting and stopping the motor A. Apparatus for automatically supplying a priming fluid to the compressor chamber upon the initial movement of the motor &c. is also provided. Specification 221,769 is referred to.

Filed: 1948-03-15
Abstract: 651,483. Fuel injectors. FRENCH, L. O. March 15, 1948, No. 7755. Addition to 650,028. '[Class 7(iii)] [Also in Group XXVIII] In a fuel injection apparatus operated by compression in the engine cylinder as claimed in the parent Specification, an adjustable pressure-operated relief valve 76 is associated with the hydaulic checking chamber 57 to determine the timing of movement of the piston structure 23, 24 and hence the beginning of injection. The hydraulic checking fluid is supplied from a reservoir 73 through pipe 74, check valve 75 and passage 19, and, on the upstroke of the checking piston 24, is forced from chamber 57 through port 13 past the relief valve 76 and pipe 77 to the reservoir. The relief valve is loaded by a spring 78 which abuts a cap 79 adjustable by a lever 86 through a cam 83 and lever 81. The upstroke of the piston structure is limited by the edge of a central recess 45 on the piston 24 which masks the port 13 to cause an hydraulic lock in the chamber 57 and hence terminate injection. The upstroke is varied by rotating the piston 24 by means of a control sleeve 55 having an arm 54. The operating piston 23 is formed integral with or secured to the pump barrel 27 which reciprocates over a fixed plunger 61 and is loaded by a spring 22. The latter maintains the checking piston 24 in abutment with the barrel so that they move as a unit. Fuel supplied from a reservoir 69 by a low pressure pump 68 through a cooler 70 is circulated through the apparatus to ensure cooling and is returned through a pipe 72. Fuel enters the barrel through ports 62 and on the upstroke is forced past a check valve 33, discharge valve 34 and through passages 37, 38 in the shank of an abutment member 35 to the nozzle 31. The valve 34 is a resilient disc preferably laminated and its periphery is pressed against a sleeve member 30 by the abutment member 35.

Abstract: 841,061. Connecting upholstery springs. ETABLISSEMENTS B. FAURE. March 11, 1957 [March 15, 1956], No. 7992/57. Class 52(4) [Also in Groups XV and XXV] A clip adapted to bind together elements of elongated shape such as for spring cushions, seats and mattresses by being wrapped round the elements when they are juxtaposed, is constituted by a thin plate bent so that it has the form of a U-shaped channel, the two sides 2, 3 of which are inclined at a small angle to each other and have substantially plane inner and outer surfaces and the base portion of which has the form of a section of a cylinder, the sides of the channel being provided with annular projection 8, 9 and recesses 6, 7 so arranged that recesses of one clip will co-operate with projections of another like clip when one of the clips is engaged over the other, thus enabling a number of clips to be formed into a supple yet strong chain from which the clips are easily removable and which is suitable for feeding to an assembly machine. The recesses 6 and the projections 8 are simultaneously formed by punching the plate and the recesses 7 and the projections 9 are similarly formed. The projections 9 are smaller than the projections 8 and the recesses 7 are consequently smaller than the recesses 6 hence when the projections 9 are engaged with the recesses 6 a slight angular displacement of one clip relative to the other is possible. The side 2 of the clip is in the form of a tongue and the side 3 has a recess which receives the tongue when the clip is bent round the elements to be joined together as shown in Fig. 6.
