Title: Improvements in magnetos
IPC: H02K21/42
Filed: 1919-10-03
Abstract: 151,162. Jackson, W. J. Mellersh-, (American Bosch Magneto Corporation). Oct. 3, 1919. Inductor machines.-In an ignition magneto of the type having a magnetic sleeve 5 rotating in the gap between the field-magnet and armature pole-pieces 2, 3, the trailing tips of the sleeve are arranged to leave the trailing tips of the fieldmagnet and armature pole-pieces at irregular angular intervals, and the interrupter is arranged to break the circuit of the primary generating winding 21 at substantially these irregular intervals. Magnetos, according to the invention, are adapted particularly for the ignition of multicylinder aeroplane engines, arranged in V-, fan, or circular formation. The drawings show a magneto for firing a 12-cylinder four-cycle engine having the cylinders arranged in two planes inclined at an angle of 45‹, the sleeve being driven at one and a half times the speed of the crank-shaft. The armature is displaced from its neutral position by an angle equal to half the difference between the adjacent irregular intervals. Figs. 2 and 3 show the trailing tips of the sleeve-members 5 leaving the trailing tips of the armature polepieces 3; at 67.5‹ later in the rotation, the trailing tips of the sleeve-members leave the trailing tips of the field-magnet pole-pieces 2, Fig. 5; at the end of a further angular interval of 112.5‹, the position of the parts is as shown in Fig. 6, and so on. At each of these ignition periods, the mechanical interrupter 27, Fig. 3, opens the circuit of the primary generating winding 21 and the high-tension voltage is directed in turn to the sparking-plugs 30 through the distributor 29.

Title: Modulating arrangements for carrier wave signalling systems
IPC: H03C1/50
Filed: 1935-08-30
Abstract: 448,595. Modulating systems. LORENZ AKT.-GES., C., 1, Lorenzweg, Tempelhof, Berlin. Aug. 30, 1935, No. 24228. Convention date, Sept. 6, 1934. [Class 40 (v)] Carrier current from a source S is modulated by applying it to the diagonals of two bridges B1, B2 each comprising oppositely-disposed resistances R and oppositely-disposed capacities C, the other diagonals of the bridges being coupled to push-pull valves U, and the modulation voltage being used to vary the bridge-arm resistances. As shown, the resistances R are pairs of diode valves V1, V2 with the anode of each connected to the cathode of the other, each pair being connected in series with a D.C. source D and with the modulating transformer M. The outputs from the bridges are fed to amplifiers U connected in push-pull relation. The modulation voltage varies the resistance of the valve-pairs V1, V2, and so shifts the phases of the output voltages in opposite directions, giving an amplitude variation when the two outputs are combined in the amplifiers U and aerial A. The quiescent value of the carrier is adjusted by varying the anode voltage of the diodes V1, V2 or by varying the capacities. The diode valves may be replaced by triodes with the modulating signal applied to their grids. The resistance variation in one arm of a bridge may differ in extent from that in the opposite arm ; or one resistance may remain constant.

Title: Improvements in or relating to the manufacture of gas from oil, by use of an oil spray injector
IPC: C10G9/00
Filed: 1947-09-08
Abstract: 636,628. Oil gas. DYSON, W. R.' Sept. 8, 1947, No. 24617. [Class 55 (ii)] Horizontal retorts, normally used for the high temperature carbonisation of coal. are converted for oil gas production by fitting an injector as shown in the Figure to the mouthpiece lid of the retort and, by means of the injector, spraying oil into the retort, which is externally heated in the usual manner, together with a quantity of air insufficient for the complete combustion of the oil and with steam. The oil is partially burnt in the retort, the remainder being vaporized and cracked to form permanent gas, which being diluted with combustion products may be mixed directly with coal gas for towns distribution. In the injector, which is made up from standard pipe fittings, steam enters through the inlet C and, flowing through a jet Cl, induces a flow of air through the air inlet A, a shutter E regulating this air flow. The air-steam mixture passes into a mixing chamber B2 to meet a jet of oil entering at B and flowing through orifice B1, an auxiliary supply of steam, through pipe C2, assisting the oil flow and keeping orifice B1 clear of obstructions. The oil is carried forward in the form of a spray and passes, with the steam and air, through an outlet pipe D which is threaded into a tapped hole in the mouthpiece lid of a horizontal retort. The temperature inside the retort is maintained at 700-800‹ C. Partial combustion of the oil occurs in the retort and the remaining oil is converted into oil gas which is withdrawn through the gas outlet pipe remote from the injector.

[Class 138 (i)] A carpet-sweeper comprises a brush roll which is driven by means of the floor wheels and is secured by supporting means capable of limited vertical movement, said means also supporting a dust pan for similar movement. Means may also be provided which permit limited upward movement of the dust pan independently of the brush roll. In the construction shown, the floor wheels 14 are provided with gear wheels 24 engaging fabric gear wheels 42 which are operatively connected to the ends of a brush roll 50. The roll has square-shaped ends 52 each engaging in a square opening in a cylindrical member 45, the ends 47 of which are bent inwardly to engage in sockets 40 formed in a hub 38. The wheel 42 is secured to the hub which is rotatably mounted on a bearing pin 28. The pin is secured to a hollow cylindrical member 27 within which is fitted a bearing member 76 for the bail 75 of the handle. The member 27 passes through a cut-away portion 37 of the casing 10. The bearing pin 28 passes through an opening in a plate 31 which is supported at each end by a spring 35. The springs act to hold the brush roll away from the surface of the carpet. The two plates 31 are connected by transverse bars 54 which support the dust pan 56. Springs 70 act to maintain the flanged edges 55 of the pan in contact with the bars 54. The sides of the pan are cut away to seat upon the ends of the brush roll. When the sweeper is in use, the brush is pressed into contact with the carpet by downward pressure on the handle, the pans also moving downwardly. Specification 454,565 is referred to.

The parts 2, 4 are held together by a cylindrical housing 1 having a shoulder 1a engaging a projection on the part 2 and a rim 1b bent over the part 4 which has a projection 31 in a recess 30 in the part 2. The parts 12, 14 are similarly held together by a housing 16 having threaded portions 21, 29. Holes 3, 5 and 13, 15, in the parts 2, 4 and 12, 14 respectively, allow free movement of the contacts to compensate for mal-alignment. The plug and socket are locked together by a nut 22 engaging the threads 21, the plug having a non- circular projection 32 entering a socket recess 33. The plug may be secured to a panel 24 by a nut 28, on the thread 29, compressing a sealing gasket 27 in a sealing ring 26 engaged by a shoulder 25 on the housing 16. In Fig. 2 (not shown) only one resilient packing is used. The thickness of the packing may be increased at the holes.
