  • Publication number: 20070143335
    Abstract: The performing of actions on an object graph that contains multiple objects. The objects are categorized into partitions. Taking into account the partitions, a particular non-final action performed on the object graph may be undone without necessarily first undoing all of the one or more subsequent actions. Instead, if the subsequent actions involved objects of different partitions than the objects that were affected by the particular action desired to be undone, the particular action may be undone without undoing the subsequent actions.

  • Publication number: 20060260161
    Abstract: An illuminated, solar powered sign is provided which in one embodiment includes a memory storage device which can be accessed with an electronics device such as a flash card, laptop computer, PDA, cellphone or other similar apparatus. Alternatively the stored data can be transmitted wirelessly to an electronics device where information related to the sale of real estate or other commodities can be reviewed.

  • Patent number: 6588173
    Abstract: A machine for packaging multiple containers wherein a flexible carrier stock is fed across a jaw drum. A plurality of containers are also moved through the machine whereby the carrier is subsequently positioned over the plurality of containers so that flexible carrier stock engages with one of the containers to form a package. The machine is adjustable to accommodate a range of container heights and sizes, carrier configurations and/or package sizes. In addition, movement of the various components of the machine is coordinated using an encoder.

  • Patent number: 5500735
    Abstract: A method and apparatus for monitoring the fiber surface development of pulps due to the refining or beating of mechanical or chemical pulps; an optical cell, fabricated with light-transparent windows, permits an incident collimated beam of light to pass through pulp stock flowing through the cell. The beam is transmitted through a polarizing filter prior to entering the cell, and through a second, crossed, polarizing filter, on exiting from the cell. The exit beam converges onto a photodetector. A gradual variation in the mass of fibers of the pulp stock is established over a predetermined range and this produces a change in the intensity of the transmitted light. As the light intensity changes, it passes through a maximum value; this is accompanied by a similar change in the photodetector electrical output signal.
