Title: Electrical machine, such as a flywheel starter generator
Inventor: HILTON JONATHAN JAMES ROBERT
IPC: B60K6/10
Filed: 2008-09-16
Abstract: An electrical machine, such as a flywheel starter generator (FSG) 2 or a flywheel alternator starter, comprises a motor 4 with a rotatable stator (outer rotor) 6, eg connected to an engine accessory drive belt pulley 14, a rotor 8, eg connected by a mechanical drive connection, eg epicyclic gearing 12, to a flywheel 10, and an energy storage medium such as a battery 16 or capacitor. When the machine is in a running mode, a current supplied to the motor 4 causes it to rotate, whereby the flywheel 10 is also caused rotate, thereby transferring mechanical energy from the mechanical drive connection to the flywheel. The running mode comprises regenerative braking and energy release states. The machine also has a starter mode in which the flywheel turns backwards against the starter torque; an idle mode in which the flywheel spins with low losses; a paused mode in which the flywheel gradually decelerates and restarting power comes partly from the flywheel and partly from the battery, and a stopped mode in which any energy remaining in the flywheel is converted into electrical charge and stored in the battery.

Title: Parity encoding/decoding
Inventor: KASAI KENTA
IPC: H03M13/00
Filed: 2009-07-02
Abstract: An encoder and decoder employ an encoding scheme corresponding to a parity check matrix which is derivable from a bipartite protograph formed of variable nodes and check nodes, with each variable node corresponding to a codeword symbol position. The protograph has groups of nodes, each group of nodes comprising both variable nodes and check nodes. Each of the check nodes in a group is of degree 2 and has connections to two variable nodes in the same group. The protograph also has check nodes of degree n, where n is the number of groups, and each of the plurality of check nodes has a connection to a variable node in each group such that the symbol positions in a codeword are interleaved between the groups of nodes. There can be two degree n check nodes and they can be connected to the same or different symbols in each group and there can be three groups. The coding rate can be adjusted by puncturing symbols within the coding scheme. A received data stream can be processed to generate packets of symbols, each being from a Galois field of dimension q, in the range 32 to 256.

Title: Improvements in transmission gear systems
IPC: F16H3/08
Filed: 1922-04-10
Abstract: 178,435. Penrod, W. F. April 15, 1921, [Convention date]. Variable-speed toothed gearing has helical teeth throughout and a double bevel self-compensation drive to a wheel R<1> which may be mounted on the differential of a vehicle. Bevel gears P', P<2> meshing with the wheel R<1> on opposite sides are secured to an intermediate shaft S<2> and to a countershaft S' respectively, and are connected by a constantly-meshing pair g<1>, g<2>. The power is equally distributed between the bevel gears by suitable means such as by allowing the shaft S<2> longitudinal play. A driving-shaft S<1> is in line with the shaft S<2>, and about their meeting ends is mounted a loose gear g<3> which may drive or be driven from a gear g<4> secured to a sleeve S<4> loose on the countershaft. A gear g<5> fast on the shaft S<1> meshes with a gear g<6> loose on the shaft S<3>. In each operative position, end thrusts are balanced by the helices of the working gears. A drive direct to the divided transmission is obtained by connecting the gear g<3> to both the shafts S', S<2> by clutches c<1>, c<2>. A higher speed is effected by driving the shaft S' through the single pair g<3>, g<4> as shown in Fig. 3, a clutch c<3> being used. A lower speed is effected by using the pair g<5>, g<6> alone with a clutch c'. The lowest speed is a double reduction obtained as shown in Fig. 2. In reversed driving, power passes from a gear g<7> through an idler g' to a gear g<8>, and through the reducing pair g<4>, g'. There are main roller bearings b<1>, b<2>, Fig. 1, and a thrust bearing e. The abutting ends of the shafts S<1>, S<2> carry fast upon them steel discs d separated by hard independent rollers d<2> constituting a thrust bearing so that the shafts move longitudinally together. The bearing is enclosed between washers d<1> and two parts in which the gear g<3> is made.

Title: Improvements in or relating to chain-type delivery devices for sheet printing machines
IPC: B41F23/06
Filed: 1951-05-02
Abstract: 720,090. Toothed gearing. MASCHINENFABRIK AUGSBURG-NURNBERG AKT.-GES. May 2. 1951 [May 19, 1950]. No. 10314/51. Class 80 (1). [Also in Group XVI]. A chain delivery for a sheet-printing machine is driven through an epicyclic gear having a sun wheel and an annulus as main members, one of which is driven and the other of which drives the chain wheel 51. Moreover, a disc 47 carrying the pins on which revolve the planet wheels 46 has a follower 53 rolling in a cam slot 54 in a wheel 40 which receives the drive initially and transmits it to one of the main members so that the planet carrier 47 is caused to oscillate (in rotation) and the chain speed is varied, e.g. in order that one of two gripper members on the chain passes a sheet to the delivery table when the. chain speed is less than the peripheral speed of the impression cylinder and a moment later, when the chain accelerates, the other gripper picks up a sheet from the cylinder. The gear wheel 40 is driven by means of its teeth, being supported loosely on its shaft, and in turn drives the sun wheel, mounted on a shaft 43 and bearing a gear 44, through a gear 42 integral with gear 40. The three planet wheels 46 engage both the teeth of a gear 45 on the sun wheel and an inner gear 57 on the annulus, loosely mounted on the hub between gears 44 and 45, so that the oscillatory rotation of the planet carrier 47, due to the eccentricity of the cam slot 54, successively retards and accelerates the annulus. An external gear 48 on the annulus drives a pinion 49 and thereby the chain wheel 51.

Title: Improvements in or relating to the production of endless coiled magnetic recording tapes provided with a guide groove
IPC: G11B5/004
Filed: 1955-04-07
Abstract: 776,489. Magnetic recording tapes. DANIEL, K., [trading as TEFI-APPARATEBAU, DR DANIEL KOMM-GES.]. April 7, 1955, No. 10358/55. Class 40 (2). A method of producing magnetic recording tapes, each in the form of a coiled endless tape, having a guide groove to guide the guide pin of a magnetic recording or reproducing head, consists in arranging as a moving driving belt an endless band having a cuttable layer, cutting a groove in the layer by means of a stylus, said groove encircling the band a plurality of times in a generally helical manner, severing the grooved band by cutting across the groove turns, the severed band thereby having a plurality of grooves running generally lengthwise thereof, providing an electrically conductive coating on the grooved side of the band, preferably by cathodic sputtering, producing a matrix band by electrolytic casting on the grooved side of the band, impressing the matrix band or a replica thereof on one or more hotworkable magnetic tapes of finite length by means of a calender using heat and pressure, winding the or each of the so-produced tapes into a coil, and welding the ends together with the impressed grooves in register to provide a generally helical guide groove in the resulting endless tape. If the tape to be produced is the same length as the endless band the groove is helically cut but if the length differs then the groove turns run parallel to the edges of the band, with stepwise displacements preferably at the same point on each revolution of the band, to run one groove turn into the next. A plurality of tapes may be produced by cutting a corresponding plurality of grooves in an endless band of width which is a multiple of the width of the tapes, then proceeding as above, and finally severing longitudinally the individual tapes before winding them into coils. The endless band may comprise a carrier layer and a superimposed cuttable layer of, e.g., wax or gelatine. The magnetic tape may be either a film-forming material throughout which is evenly distributed a magnetizable substance, e.g. iron dust, or a non-magnetic carrier having a superimposed magnetizable layer, and in the latter case the matrix band may be arranged to cut right through the layer to separate the ridges between adjacent groove turns.
