Filed: 1977-10-05
Abstract: The needle bar (1), which carries an insertion point (9), is bent at right angles in the manner of a camshaft around the writing instrument (7), an ink pen. The longitudinally movable drop-piece (3-6) has a tubular part (3), which rests on the needle bar (1), and a guide (4) for securing against free twistability. The axis of the compass joint (5) is arranged perpendicularly to the plane of drawing, so that the drop-tube (3) with the ink pen is adjustable about this axis relative to the needle bar (1), as a result of which the radius of the compass is determined. A braking spring for fixing the set compass radius is provided in the region of the compass joint (5). As a result, the ink pen (7) can be guided perpendicularly to the drawing surface irrespective of the radius selected. <IMAGE>

In a programmed control system for a stage lighting installation a lamp group 11 is fed from a supply 2 via a dimmer 3, comprising a transductor 31 provided with a control winding 32. The control winding is fed from a direct current supply 10,12, via a change-over relay 6, from a manually adjustable potentiometer 41 or a potentiometer 51 in a short-time memory 5, comprising a relay register 52, 56. The change-over is controlled by a sensing device 7, incorporating a potentiometer 71, is consecutively connected to the dimmers of a uniselector. During recording the lamp group is adjusted to the desired light intensity by the manual potentiometer 4 and the voltage across the control winding is sensed by the device 7 and the voltage tapped from the potentiometer 71 is brought to equality with the tapped voltage from the manual potentiometer 41 by step-wise adjustment of relays. The potentiometer 51 in the short-time memory is adjusted simultaneously and the equality setting of the relays is read at terminals 530-532 in binary rotation by a card punching device, not shown. During reproduction the punch card sets the appropriate relays in the short-time memory 5 and the control winding 32 is energized accordingly. The control of a lamp-group is taken over during reproduction by the operator bringing to the voltage across the potentiometer 41, indicated by a voltmeter 42, into equality with the voltage across the control winding 32, indicated by a voltmeter 54, and then changing-over the relay 6 by operating a switch 43. In a modification, Fig. 3, not shown, the manual system and short-time memory are duplicated permitting control from more than one position and and allowing the lamp groups to be controlled from one of the short-time memories while the other is being set by the punch card system.

Apparatus for detecting the presence of two overlapping documents in a feed path comprises a photo-cell 95 which receives light transmitted through the documents from a source 90, and an air jet 75, or other means such as a vacuum source or mechanical or electrical means, for separating any overlapping documents, thereby reducing the intensity of light reaching the photo-cell 95 and providing an output which may be used to stop the document feeding mechanism. The detector circuit and cell 95 are so arranged that two overlapped documents in flat superposed condition will not stop the feed mechanism, but will do so if the edge of the overlapping document is raised by the air jet 75. as shown in Fig. 2 (not shown), to cause the light beam to be attenuated. The documents are separated from the top of a stack 10 by a belt 12, between a forward moving belt 13 and a reversely moving belt 14, where overlapping documents are usually held back, and are then fed by rollers 20 past a reading station 30 to a stack 40. In Figs. 4 and 5 (not shown), documents are separated from the bottom of a stack 10 and the air jet 75 is arranged between the station 30 and the detecting cell 95, so that the leading edge of an overlapping document is lifted. The air jet 75 can be replaced by a source of vacuum, or by mechanical or electric means.

Abstract: 1,083,002. Selective signalling. MARCONI CO. Ltd. Aug. 3, 1965 [Oct. 23, 1964], No. 43393/64. Heading G4H. A pay-television system of the type in which each receiver transmits to a central office signals indicating the particular television programme being received, the signals being transmitted at a particular time within a cycle established by timing pulses transmitted by the central office, whereby from the time of reception of the programme indicating signals the central office can determine from which receiver they originated, is characterized in that to establish time cycles the central office transmits two trains of timing pulses a " field pulse " train, the pulses of which demarcate complete cycles, and a " line pulse " train of a relatively higher frequency (e.g. 32 times the field frequency) which demarcate a plurality of subcycles within a cycle, and in that each receiver includes two delay devices, the combination of which is unique to the particular receiver, whereby by using one delay to delay a field pulse a particular sub-cycle can be selected and by using the second to delay a line pulse a particular time within the selected sub-cycle can be selected, thus indicating to the receiver the time at which it should transmit its programme indicating signals. In the preferred embodiment each frame pulse is 640 ms. long and their period is 20,480 ms. which is divided into 1024 receiver periods, each of 20 ms. The line pulses are 20 ms. long and have a period of 640 ms. so that each sub-cycle contains 32 receiver periods. Field pulses are delayed by multiples of the field pulse duration, 640 ms. (i.e. by multiples of sub-cycles) and line pulses are delayed by multiples of the line pulse duration, 20 ms. (i.e. by multiples of receiver periods). The programme indicating signals each comprise a pulse of a carrier frequency, frequency modulated in accordance with the particular programme. Each group of 1024 receivers in the system uses a different carrier frequency. At the central office the received programme indicating signals are appropriately analysed to prepare an account for each customer. A visual display on cathode-ray tubes, one for each available programme is also produced, the field and line pulses determining 1024 positions on each tube face which positions are brightened if the corresponding receivers are actually receiving the programme to which the tube corresponds.
