  • Patent number: 8617020
    Abstract: A continuously variable transmission having a transmission input (60) and a transmission output (114) is described. The transmission has a variator (56). This is a device which transmits drive at steplessly variable ratio. It further comprises an epicyclic gear arrangement (58) incorporating a clutch arrangement (152). The epicyclic gear arrangement has three rotary members. One of these is coupled to a planet carrier (86) having at least one planet gear (94). Another of the rotary members is coupled to a main gear (90) meshing with the planet gear. The clutching arrangement serves to couple the remaining rotary member to either of first and second alternative gears (96, 98), both of which mesh with the planet gear and which rotate at different speeds. One of the aforesaid rotary members is coupled to the transmission input at a fixed drive ratio. One of them is coupled to the variator output. The last of the rotary members is coupled to the transmission output.

  • Publication number: 20130296096
    Abstract: The invention is concerned with a continuously variable transmission incorporating a variator of the type having at least two co-axial races (D1-D4) between which drive is transferred at a continuously variable variator ratio. The variator races are mounted for rotation about a variator shaft (15). The transmission has a layshaft (18) which is laterally separated from the variator shaft. It has two epicyclic gears. A splitter epicyclic (14) has an input member driven from the transmission input (10) and two output members arranged respectively to drive the layshaft and the variator shaft. A recirculater epicyclic has first and second input members for coupling respectively to the variator shaft and to the layshaft and a recirculater output member. An arrangement of clutches is provided for selectively engaging any of at least three regimes. In one regime the recirculater output member drives the transmission output. In another the layshaft drives the transmission output.

  • Publication number: 20130126238
    Abstract: An oil and gas well shaped charge perforator capable of providing an exothermic reaction after detonation is provided, comprising a housing (2), a high explosive (3), and a reactive liner (6) where the high explosive is positioned between the reactive liner and the housing. The reactive liner (6) is produced from a reactive composition which is capable of sustaining an exothermic reaction during the formation of the cutting jet. The composition is a pressed i.e. compacted particulate composition comprising at least two metals, wherein one of the metals is present as spherical particulate, and the other metal is present as a non-spherical particulate. There may also be at least one further metal, which is not capable of an exothermic reaction with the reactive composition, present in an amount greater than 10% w/w of the liner. To aid consolidation a binder may also be added.

  • Patent number: 8360309
    Abstract: Methods of reducing transaction time in a self-service terminal are described. The methods involve pre-stacking a defined amount of media, such as a commonly withdrawn amount of money, before the user has performed any service selection. During service selection, the user is given an option to withdraw the defined amount of money and if the user selects this option, the pre-stacked amount is dispensed. If the user selects an option to withdraw a different amount of money, a second dispenser in the self-service terminal may be used to stack and dispense this different amount.

  • Patent number: 8201728
    Abstract: A self-service terminal (SST), such as an ATM, comprises a processor, and two functionally similar devices, for example cash dispense units, and an input/output (IO) port. The processor receives status data from each of the similar devices and determines which set of status data to communicate to a remote host via the IO port dependent upon device status and health parameters contained within the status data.

  • Publication number: 20120142477
    Abstract: A multi-regime continuously variable ratio transmission has a transmission input shaft, a transmission output shaft, and a ratio varying unit having a rotating input and a rotating output, the rotational axes of the input and the output being coaxial. A shunt having first and second epicyclic gear sets is connected across the ratio varying unit. One gear set has an input driven by the input shaft and an input driven by one side of the ratio varying unit and the other gear set has an input from the first gear set and an input from one side of the ratio varying unit. The gear sets rotate about a common axis and are offset with respect to, and parallel to, the rotational axes of the input and output of the ratio varying unit. A clutch is operable to selectively connect the output of the second gear set to the output shaft.

  • Publication number: 20120130810
    Abstract: A method is provided for dynamically adding customized advertisements with media content on digital media storage devices. A user may provide identification data to an automated machine or salesperson selling the media content at a retail location. Based upon the identification of the user, advertisements may be selected to be added to the media content. The selection of advertisements may be based upon previous transaction data, the genre of the media content, or characteristics identified for the user. Users may also select to change the quantity of advertisements to view based upon fees paid by the user for the media content. The user may pay additional fees to view less advertisements and the user may pay fewer fees and have more advertisements included with the media content.

  • Publication number: 20100197447
    Abstract: The invention concerns an arrangement for control of a continuously variable transmission. The transmission includes a variator (10) having a movable torque transfer part (rollers 18) whose position corresponds to a variator drive ratio. A hydraulic actuator (28) is arranged to exert an adjustable force on the torque transfer part. The transmission further comprises a flow control arrangement which is arranged to receive as control inputs (a) the current position of the torque transfer part and (b) a demanded position for it. The demanded position may for example be determined by driver input. The flow control arrangement is adapted to supply through a supply outlet which communicates with the hydraulic actuator a flow of fluid which is modulated in accordance with an error between the two control inputs. The flow of fluid increases with increasing error.

  • Patent number: 4087677
    Abstract: In the transmitter portion a multiplexer multiplexes first digital data and first teletype signals to provide first digital data signals. The first digital data signals are converted into second digital data signals having a different form than the first digital data signals by a Viterbi coder. A PSK modulator responsive to the second digital data signals provides a first PSK signal for transmission. In the receiver portion a PSK demodulator receives a second PSK signal containing third digital data signals having multiplexed second digital data and second teletype signals with the third digital data signals being extracted from the second PSK signal. A Viterbi decoder converts the third digital data signals into fourth digital data signlas having a different digital form than the third digital data signals. A PSK demultiplexer is responsive to the fourth digital data signals to separate the second digital data and the second teletype signals for utilization.
