Filed: 1981-01-23
Abstract: A document to be copied is inserted into a recirculating document feeder of a moving document copier at an entry station (21) and is edge aligned against a reference surface (55). The feeder has a loop-shaped document path to recirculate a document once for each requested copy afterthe first. A turn-around guide (38) is pivoted into or out of the document path to direct the document into or out of the recirculating path. The reference surface (55) is interrupted in the vicinity of the guide. The guide is so disposed as to skew the leading edge of the document so that it is displaced slightly from the reference surface (55) to avoid document jams. The document is subsequently re-aligned against the reference surface (55) for rescanning to make another copy. A copy-request counter operates to pivot the guidetothe document-intercept position so long as more copies are needed. When all requested copies have been imaged, the document is allowed to proceed to an  l exit tray (4 0 ).

Abstract: A circuit which achieves an improved speed/power product when switching capacitive loads. A high capacitance first node (A) is connected directly to pull-down means (7, 8) and is connected to pull-up means (2) through the channel of a depletion transistor (1). The gate of the depletion transistor (11) is controlled by a signal produced by inverting the voltage at a second node (8) formed by the junction of the depletion transistor (1) and the pull-up means (2). An output signal is taken from the second node (B). The depletion transistor (1) thus acts to isolate the first node capacitance (Cp) during pull-up. This results in an improved speed/power product when switching logic levels on the high capacitance node (A).

Abstract: @ The working depth of an implement attached to the 3-point hitch of a tractor is normally controlled by a draft load error signal formed as the difference between a load set point signal and an actual load signal provided by a draft sensor. For lowering the implement into the ground and raising it a depth position lever (50) actuates a transducer (54) to provide a position set point signal A(3) which is compared with an actual position signal from another transducer to form a position error signal. A large position error takes precedence over a smaller load error. In order to provide the load set point signal without the need for a separate lever, a swith (58,60) is mounted on the lever (50) and, when depressed, causes the draft load set point signal to increase up to the desired value as the implement is lowered into the ground by pushing the lever (50) forwards.

Abstract: A thermal transfer colour printer is disclosed for printing colour images on individual sheets of paper. One sheet of paper (24) at a time is removed from a stack of paper stored in a cassette (22) and is transported by a reversible platen roller (74) in a first or forward direction at a first predetermined rate. While the sheet of paper (24) is gripped between the reversible platen roller (74) and one or other of pinch rollers (82, 84), slack is removed by a slack removing device (236). A multicoloured ink ribbon (108) with successively arranged colour segments is also transported in the first direction at the same predetermined rate. A thermal printhead (118) presses against the reversible platen roller (74) to press the ink ribbon (108) and sheet of paper (24) together as they move in the first direction. Energisation of the thermal elements (120) on the thermal printhead (118) by colour component signals corresponding to the current colour of the ink ribbon causes the particular current colour to be thermally and selectively transferred to the sheet of paper. The thermal printhead (118) then disengages from the platen roller (74) and the sheet of paper is transported in a set distance in a second direction opposite the first direction, and at a second predetermined rate, and the process of thermally transferring other colours to the sheet of paper is repeated. During the back and forth movement of the sheet of paper, the reversible platen roller (74) and the pinch rollers (82, 84) continuously grip the sheet of paper in order to control precisely the position of the sheet of paper and thereby avoid distortion. A complete colour image is formed on the sheet of paper (24) by superimposing the multiple colours of the ink ribbon (108) as the sheet of paper and the different colours of the ink ribbon repeatedly move past the selectively energised thermal elements (120) of the thermal printhead (118).

Abstract: The brush manufacturing machine (1) (Figure 1) has three-phase servo drive motors (8, 8a, 8b) for positioning workpiece holders (7), in which brush bodies (6) are clamped for processing. These motors result in a brush manufacturing machine which, in total, requires virtually no maintenance in respect of the drives, the drives also being insensitive to the development of dust which is unavoidable in brush manufacture. Due to the favourable weight per unit power of these three-phase servo drive motors, they can also readily be built on virtually directly next to the positioning devices, which allows a high required positioning speed due to their comparatively low weight. <IMAGE>
