Abstract: 1,229,135. Keyboard coding apparatus. NATIONAL CASH REGISTER CO. 1 Oct., 1969 [14 Jan., 1969], No. 48l92/69. Heading G4H. In a keyboard operated data input device depression of a selected key 12 causes a corresponding coded shutter 38 to selectively block the paths between a number of radiation sources 74 and a single sensor 80, the sources being sequentially scanned by pulses from a ring counter 90 which is continuously driven by an oscillator 92 and the resultant pulse train passed to a number of gates 96-102 which are sequentially enabled also by pulses from the counter 90. The gates are NAND gates so that pulses of different lengths appear at the gate outputs according to whether the path from the corresponding source to the sensor is or is not blocked. Each coded shutter 38 has a strobe portion (62), Fig. 3 (not shown), which blocks its corresponding radiation path after all the other blocking portions on the shutter have blocked theirs, and thereby produces a timing signal which is used to energize the scanner 120. The scanner 120 gates, shapes and positions a train of seven pulses from the oscillator 92 which enable the gates 112-117 in synchronism with the gates 96-101 and thus read out the coded signal into, e.g. a shift register (not shown). A control bit, generated by the coded shutter, and read out between the last data bit and the strobe bit blocks the scanner 120 and prevents the data word being read out more than once. The scanner 120 remains blocked until a "ready" signal is received from the shift register and until the depressed key is released. The radiation sources may be gallium arsenide mesa light emitting diodes and the sensor a silicon photo-electric cell.

In Fig.1, roll of an aircraft is effected by rotating a horned control wheel, indicated at 23, about an axis XX and pitch is effected by axial movement of the control wheel to rock a control column 11 through an arc AA. The control wheel is fixed relative to a cylindrical member 25 which is mounted on ball-bearings 27, 27<SP>1</SP> so that it is movable rotationally and axially relative to a cylindrical member 21 fixed relative to control column 11. The rotational movement is resisted by pre-loaded springs such as 49 and a signal dependent on the rotational force applied is produced by the movement of a differential transformer type pick-off 55. The axial movement is resisted by pre-loaded springs such as 39 and a signal dependent on the axial force applied is produced by the movement of a differential transformer type pick-off 57. When the aircraft automatic pilot is in operation the signals from the pick-offs are respectively applied to the roll and pitch channels to effect control. These signals may be proportional to the forces applied or may be made non-linear by utilizing several springs with different amounts of lost motion so that they become effective at different force levels.

Abstract: 1289378 Digital transmission systems SIEMENS AG 15 Sept 1970 [16 Sept 1969] 43959/70 Heading H4P Received signals are analysed for quality also amplitude and if both conditions are present (absent) for more than a determined time, receiving equipment is switched on (off). Parallel data transmitted by FSK is received at a terminal FL and passed normally through an amplifier VE, bandpass filters F1-F3 and amplifiers V1-V3 to demodulators and low pass filters D1-D3 which detect the transmission of frequencies fl-f4 of each group A-C. An analyser circuit AS analyses the quality of received data and determines the probability of a transmission fault, e.g. the code condition. If one frequency only is detected in each group a signal appears online 8 which is passed through a decoupling stage E to AND gate G together with voltages from amplifiers V1-V3, which if up to a determined level causes with an E input an output to be supplied through a delay ZG, e.g. an RC network to a bi-stable trigger K, e.g. a Schmitt trigger circuit which switches on the receiving equipment. In an improvement the spacing combination of the frequencies f1-f4 at the commencement of transmission may be monitored by arranging the circuit AS to apply a signal direct to gate G if, within the interval determined by the delay element, the spacing combination appears. In a further modification a fault signal on line 9 drives the outputs circuits of demodulators D1-D3 into a specific state so that parasitic voltages produce no output signals on lines 1-4 until commencement of transmission. Before transmission it is advantageous if the output lines carry the spacing combination so that this exists at the commencement of transmission. Telephonic reception may be applied via a hand set contact kl to a receiver FSP and a return " good " or " bad " acknowledge signal may be transmitted from RS through contact k2 in parallel with a low frequency speech transmitter amplifier PV.
