Abstract: 742,768. Ignition; fuel injection. TEXACO DEVELOPMENT CORPORATION. Oct. 29, 1953 [Nov. 6 1952], No. 29917/53. Classes 7(3) and 7(4) [Also in Group XXXVII] In an-engine having a shrouded inlet valve 20, Fig. 1, for causing air to swirl in the cylinders 10, a system for injecting fuel into asegment of the swirling air, a sparking plug 50 located adjacent the fuel nozzle 30; an ignition device comprising breaker contacts 60, 62, and an igni -  tion coil 70 and battery 74 for energizing the plug 50 when the contacts are opened, actuating means, coupled to a fuel-injection system such as a projection 68 on the fuel-pump plunger 36, are' arranged to open the contacts 60, 62 at a fixed time' after the initiation of fuel injection so that the first increment of the injected fuel is ignited as-soon as it mixes with the air to form a combustible mixture. FUEL INJECTION. The inlet poppet valve 20 has a semi-circular shroud 20A, which causes the incoming air to swirl around the cylinder axis at a rate of about six times the engine speed. The nozzle 30 which projects into the cylinder above the' piston T.D.C. position sprays fuel in a coneshaped form into the swirling air to impregnate a segment thereof at one side of a cylinder diameter to form a patch of combustible mixture; the spray is directed downstream and across the swirling air and the injection rate is correlated with the velocity and density of the air to impregnate the latter at a controllsd fuel-air weight ratio of 0.04-0.08. The nozzle is connected by a pipe 32 to a fuel pump 34 which is actuated by the plunger 36 from a cam 38 driven by the crankshaft, not shown; the pump 34 is supplied with fuel from a tank 42 by a transfer pump 44. IGNITION CONTROL. The sparking plug 50, which is located 45 degrees downstream from the injector 30; ignites the first increment of mixture on each cycle to establish a flame plant. The contact 60 is -adjustable for timing purposes; In a modification the contact 62 is operated by a diaphragm the underside of which is subjected to the pressure of fuel in the pipe 32. In a further modification, the pipe 32, Fig. 4, has a section 90 of reduced diameter around which is wound a strain-sensitive wire 92 that may be bonded thereto; the wire 92 forms a bridge circuit with resistors 93, 94 and 95 across two terminals of which is connected the battery 74 and ignition switch 72 whilst across the other two terminals is arranged an inductor 96 that serves as an electromagnet to operate the contact 62. When fuel flows along pipe 32 the bridge unbalances and causes energization of the inductor and hence actuation of the contact 62. Specification 596,846 is referred to.

Title: Improvements in or relating to bag closing and bag filling and closing machines
IPC: B65B51/07
Filed: 1933-10-30
Abstract: 415,279. Bag-sewing machines. BAGPAK, Inc., 220, East 42nd Street, New York, U.S.A.-(Assignees of Cundall, R. N., and Cundall, L. A.) Oct. 30, 1933, Nos. 30093, 30094, and 30095. Convention dates, Nov. 2, 1932, April 14, 1933, and Sept. 9, 1933. [Class 112.] Paper bags or sacks are filled with cement &c., closed and secured by stitching, an adhesive tape is applied to cover the stitches, and the string and tape is severed between the bags. The filling is carried out from an annular rotary hopper 1, Fig. 1, from which depend a number of extensions 4 with spouts 5. The filled bags are next transferred to a conveyer system which passes them through a sewing station C, a station D at which tape is applied, a pressure applying station E, and a severing device F. When the bag is ready for closing, the upper edge is seized by the inner runs of a pair of endless belts 150, Fig. 22, which carry it away towards the sewing mechanism 350. The belts form part of the main conveyer system, shown in plan, which presents the bag in turn to the sewing mechanism, the tape-applying mechanism, the pressure applying-mechanism and the severing device. The belts 150 pass round pulleys 151, 152, 213, 214, the two latter of which are made to rotate with pulleys carrying belts 217 passing round pulleys 218, 219. The opposed runs of the belts are maintained together by series of pulleys 235, 240, and one side of the system is biassed towards the other by springs 226. The speed of the belts is preferably greater than that of the grippers G, G<1>, so that the bag-mouth is maintained in a stretched condition. The bottom of the bag is supported on an endless belt 250, Figs. 1 and 25, the upper run of which is kept in position by rollers 251 in frames 252 adjustable by screws 253. The sewing head 350, Fig. 25, is on an arm 353 pivotally mounted on a horizontal shaft 354, in a bracket 351, in axial adjustment with the drive shaft 356 of the sewing head. The head is supported by a roller 357, Figs. 25 and 26, bearing on the lower and outer edge 360 of the arm 353. Extensions 361, 363 carry set screws 362, 364 for limiting the forward travel of the lower part of the head. As the bag mouth moves through the machine, the throat portion of the sewing machine moves forward with it as each stitch is being made, and returns for the next. In a modified arrangement, Fig. 30, the sewing-head is positively caused to oscillate. The arm 353 carrying the head has pivoted upon it an arm 418 having a roller engaging a groove in a cam 416. Adhesive tape is applied over the stitching, and the tape and stitching between the bags is severed.

Filed: 1970-06-23
Abstract: 1304256 Radar; aerials SIEMENS AG 23 June 1970 [24 June 1969] 30361/70 Headings H4A and H4D A radar system comprises a directional aerial array, the individual elements of which are fed via adjustable phase shift devices, whose maximum phase difference in the operating frequency band does not exceed 360 degrees, and means to transmit simultaneously from said array a plurality of separate radar signals having different carrier frequencies. As described, an array arrangement 10 comprises two planar directional arrays, in each of which 25 dipoles are arranged on a respective side of a box 18 having radiation opaque partition walls. The near-side array is illuminated by a cluster of four horn radiators 11 to 14 each of which is supplied with a radar signal of different frequency. Said radar signals are produced by separate transmitters S1 to S4, which are connected through T/R switches SE1 to SE4 to the horns. Echo signals received by the horns are coupled through the T/R switches to receivers E1 to E4. Each dipole 15 of the nearside array is connected through an adjustable phase shift device 16, which may be electrically controlled, to an associated dipole 17 of the far-side array. The values of phase shift provided by the devices 16 are arranged so that a curved wave front received from a horn by the nearside array is transmitted by the far-side array as a flat wave front, directed as required in azimuth and in elevation. The axes of the horns are relatively tilted and because of these, and of their different frequencies of operation, four beams are radiated in different directions from the far side array. The individual radar signals are preferably pulsed, and they may be of different powers. The signals may be noisemodulated, and analysis of the echo signals may utilize correlation detection techniques.

Abstract: 930,784. Disc and drum brakes. TELEFUNKEN G.m.b.H. Sept. 7, 1959 [Sept. 5, 1958], No. 30411/59. Class 103 (1). [Also in Groups XXIV and XXXVIII] In a braking device, for magnetic tape recorders, a graphite disc 1, freely mounted on a shaft 2, is forced by spring 11 into engagement with an annular felt pad 10, Fig. 2, carried by a steel disc 7 fixed to shaft 2 by a pin 9, the spring 11 being adjustable by nuts 12, 13. A brake shoe 3 on arm 4<SP>11</SP> of lever 4, is forced against disc 1 by an adjustable spring 6 with a force which is decreased or increased by frictional drag depending on the direction of rotation of disc 1, the arm 4<SP>1</SP> of lever 4 being pivoted at 5<SP>1</SP>. When discs 7 and 1 are rotated clockwise, the braking force on disc 1 is reduced and the frictional coupling between discs 7 and 1 overcomes the braking force applied to disc 1, the disc 7 and 1 continue to rotate together and the shaft 2 is braked by shoe 3 via discs 1 and 7. For counter-clockwise rotation, the braking force on disc 1 is increased and overcomes the frictional coupling causing relative rotation of discs 1 and 7, the shaft 2 then being braked by the pad 10 engaging disc 1. When applied to tape recorders, one device is mounted on the shaft of one spool and a second device, but with arms 4<SP>1</SP>, 4<SP>11</SP> reversed, on the shaft of a second spool. When the spools are rotating counterclockwise the first spool will be the supply spool and have the greater braking force.
