Abstract: A cord guide unit 2 for a roll-up blind 4 having a top rail 6 in the form of an extruded section. The guide unit 2 is moulded from a plastics material and is dimensioned to frictionally fit within an end 20 of the top rail extruded section 6. The guide unit 2 includes side walls 23, 24 which are joined by two intermediate sections which provide upper surfaces joined to end surfaces by curved surface portions for guiding the travel of a cord for operating the blind through 90.degree.. An aperture 52 is provided between the two intermediate sections for the passage of a loop of the cord. An end flange 22, which provides a closure for the end 20 of rail 6, is spaced from one of the intermediate sections thereby providing another aperture 54 within which is mounted a pivotal cord wedging element 56. A draw section of the cord passes through aperture 54 and can be selectively wedged against an end surface of the adjacent intermediate section by wedging element 56 to hold the blind in a rolled-up position.

Abstract: A cash counting machine including a bill feed mechanism that transfers bills individually from an input hopper to an output tray including a microprocessor control system. The machine operates in two modes, including a batch mode in which it transfers a selected number of bills, as selected by an operator, to the output tray, and a count mode in which it transfers all of the bills to the output tray and keeps a running count of the number of bills, as well as the total value of money if the operator has entered a denomination value. The microprocessor also determines whether the bills are of the proper size. In an alternate embodiment, for use with currencies in which the different denominations have different sizes, the microprocessor determines the size of the bills and their respective denominations.
