Title: Jet writing
IPC: G06K15/10
Filed: 1975-07-04
Abstract: 1517012 Facsimile reproduction SIEMENS AG 4 July 1975 [19 July 1974] 28374/75 Heading H4F Jet writing apparauts comprises a jet-emitter to direct a beam of writing fluid of constant strength onto an image registering carrier, displacement means to relatively move the jet and carrier so that a line image (i.e. comprising parallel lines) is drawn on the carrier, and speed modulating means to control the speed of the relative movement so that the image line varies in intensity. The slower the movement across the carrier the denser the line plotted. The carrier, for example a sheet of paper running between rollers (2, 3, Fig. 1 not shown) may either be continuously moving or be stepwise shifted at the end of each line so that the line spacing is constant and of the order of a line width. As described a jet of ink moves transversely to the carrier and its speed is controlled by a circuit (e.g. Fig. 3 not shown) which produces a voltage corresponding to the level of charge on the screen (22) of a charge-storage c.r.t. In another embodiment (Figs. 4 and 5 not shown) the emitter is controlled by pulses causing the emitter to take a given number of equal length steps in each line, the time interval between successive steps being varied according to the density required so that a "dot" image is formed. The length of the steps of a line is chosen by preselecting the amplitude of the pulses and the intensity of the dot is determined by the duration of the pulse. The apparatus may be used to reproduce a stationary television picture or to record the energy spectrum of an EEG trace. An analogue image can be derived from digital information by addition of a D-A converter, and the jet may be caused to write in both directions (R-L and L-R) across the carrier.

IPC: H03K21/00
Filed: 1959-08-21
Abstract: 912,861. Electronic counting - apparatus. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. Aug. 3, 1960 [Aug. 21, 1959], No. 28585/59. Class 106 (1). A counting circuit comprises a plurality of bi-stable stages, the state of the count being determined by two of the stages being in a different state from the rest, the application of each successive input pulse causing one of the two " set " stages to be reset thereby setting the succeeding stage. As shown, a counting circuit comprises bi-stable stages A-E, input pulses to be counted on a line DR successively changing over a bi-stable circuit BC to produce counter driving pulses alternately on leads OL, EL. Initially, the circuit is reset by a pulse applied to a lead RS so that all the bistable circuits are in the " reset " condition. The first counting pulse changes over the circuit BC, the output on the lead OL setting a bi-stable circuit ST to cause the stages A, B to assume the " set " condition. On receipt of the next counting pulse, the circuit BC is reset to produce an output on the lead EL. A gate G1 which receives inputs from the lead EL and from the output LA of the stage A is opened to reset the stage B, the reset output of which is applied to cause the stage C to assume the " set " condition. The third pulse resets the stage A, thereby setting the stage B, the stage C remaining unaltered. Counting proceeds in this way, the eleventh input pulse causing the circuit to assume the state assumed after the first pulse. The bistable stages may comprise cross-coupled transistors.

A touch display includes means for displaying images, a plurality of touch-sensitive regions each of which consists of a single area sensitive to a change in impedance presented by touching by the human body, and placed adjacent to the area, a portion of the means for displaying visible images at which different images may be displayed at different times, and a plurality of electrical circuits each connected to an area. In Fig. 2, pairs of electrodes such as SE1, SE2 on the screen of a cathode-ray tube display DC are connected to respective bridge circuits (only one shown) so if the operator touches each electrode of a pair the capacitance of his body unbalances the respective bridge producing a signal from a respective transformer T2 which after compensation for stray phase shifts at P and amplification at A has its phase detected at PSD to indicate which electrode is involved to a computer K which may then change the display at DC. The units A and PSD may be time shared. A modification has only one electrode per bridge. Fig. 4 shows row and column wires connecting contacts SP00- SP33 bridgeable by skin resistance of the operator's finger on the display face to transformers to constitute bridge circuits selected ones of which are unbalanced in selected senses by the skin resistance to indicate finger position by producing a signal with one of two phases in one of transformers T8, T9 and in one of transformers T10, T11. Which transformers are involved is detected by shorting transformers T8-T11 in turn and detecting when the signals in wires RI, CI disappear. A modification has the row and column wires connected to logic circuitry to identify the contacts actuated, the row wires being also connected to a positive voltage source via resistors and the column wires being also earthed via resistors. Use in man-computer interaction for control of air traffic or industrial plant is described. Reference has been directed by the Comptroller to Specifications 1,046,757 and 1,097,094.
