  • Patent number: 7148327
    Abstract: A process for the preparation of soluble proteins of high molecular weight with little or no damage to the structural integrity of the proteins. The process is economically and environmentally acceptable by virtue of the cost of reagents that are used, and the recycling of some of those reagents, and is suitable for the production of soluble proteins on a large scale. The process includes a first stage using oxidative sulfitolysis followed by a second stage using mild conditions to extract the soluble protein. In the case of wool as the protein source the process leads to the production of soluble keratin proteins fractionated into the classes S-sulfonated keratin intermediate filament proteins and S-sulfonated keratin high sulfur proteins.

  • Publication number: 20060117885
    Abstract: An actuator such as a vehicle hand brake actuator is disclosed. The actuator includes an electric motor (18) which drives an orbital gear box (20) which in turn has an output connected to a pulley (60) for applying a load to cables (62) to apply the brake. A pinion gear (24) is mounted on the output of the motor (18) and drives a pinion gear (27) which in turn meshes with a spur gear (30) connected to input shaft (36) an eccentric (42) for driving the gear box (20). The orbital gear box (20) has orbit gears (50, 52) which are fixed together and which have a different number of teeth to provide a gear ratio. The gear (52) meshes with an output gear (56) which in turn is fixed to the pulley (60).

  • Publication number: 20060112000
    Abstract: A stop quantity order (SQO) on a market-traded instrument for a computerized trading system. An order to buy [sell] instrument X is an SQO if, in addition to a limit price, and a stop price, it also specifies a stop quantity SQ. It is triggered by either of the following two conditions: The market's best offer [bid] price for the instrument is greater [less] than the stop price, or the market's best offer price equals the stop price and the quantity offered [bid] at the best offer [bid] price is less than or equal to the stop quantity. Once triggered, it is submitted to the market as a limit order at the limit price. General stop quantity Orders (GSQO) are similar to SQO's, but use two markets, one as a trigger instrument, and one as a trade instrument. An order to buy [sell] instrument X is a GSQO if it specifies a limit price, stop price, stop quantity SQ, a stop instrument Y, and a stop direction SD (bid or offer).

  • Patent number: 7028572
    Abstract: A pitch transfer gear transmission which enables drive to be transmitted from a gear of having one modulus (42) to a gear having another modulus (46) includes at least two gears (12,16) which have a different number of teeth and which are able to rotate relative to one another, so that the teeth of the two gears (12,16) can form a gear modulus of a first value at one part of the periphery of the gear, and a gear modulus of another value at another part of the periphery of the gear. Continuously variable transmissions are formed by providing an input or output gear (42,46) which has a modulus which varies along the length of the gear. Pitch transfer gear assembly (30) engages with the input or output gear (42,46), and is moveable by a mechanism (59) along the length of the gear changing modulus, so as to set the drive ratio of the transmission.

  • Patent number: 7029175
    Abstract: Certain embodiments of the present invention relate to a collision detection system. The collision detection system includes a position indicator for determining an actual position of a component connected to the collision detection system. The system also includes an error calculator for determining a position error between the actual position and a selected position. The system further includes a comparator for comparing the position error to a position error limit. The comparator generates a halt signal based on the position error and position error limit. The system also includes a motion controller for controlling motion of the component. The motion controller stops motion of the component based on the halt signal. The comparator generates a halt signal when the position error is equal to or greater than the position error limit.

  • Patent number: 6704030
    Abstract: A provisioning system includes an interactive display that provides graphical feedback to a craft worker, or user. The interactive display indicates to the user possible provisioning schemes and may also indicate actually provisioned paths. Graphical templates provide a visual indication of provisioning topologies and a variety of interactive display techniques, such as pull down menus, dialog boxes, color coding, icons, and affordances, for example, may be employed in conjunction with the graphical templates to provide visual cues regarding network provisioning to a user. A wizard may be employed to step a user through the provisioning process.

  • Patent number: 6615298
    Abstract: The invention is a method and system for providing a standard interface between a client and a plurality of peripheral devices. The interface is established through creating an interface object and/or a peripheral object in an object oriented development environment of a data processing system. The method and system includes both the object creation environment and the method of object utilization. In one embodiment, the client requests and stores an interface object from a server and establishes an interface object by storing object methods and object properties within the interface object by utilizing a programming interface. The user selects a peripheral device from a collection of devices; the client then request; the server to create a peripheral object corresponding to the selected peripheral device. The peripheral object is created and stored within the client. Communication between the client and the peripheral device is established by implementing the created object's methods and properties.

  • Patent number: 6587832
    Abstract: Method and system for obtaining and using observed market rates in estimating suitable market-based compensation for one or more jobs. Each observed market rate is assigned a job family and a combination of a job category and a job level of responsibility (C/L). Median market rates and average market rates are observed for different job families and are combined in a novel way to produce job family factors and C/L factors that, when multiplied together accurately reflect market rates for that job, even for a combination of job family and job C/L that is not represented in the data.
